Abstract

Quantum computing (QC) imitates particle behavior at the sub-atomic level. Quantum gates are based on quantum mechanical phenomena such as superposition and entanglement. The obstacle to the realization of reversible computing is the huge number of operations in terms of quantum gates. Therefore, novel designs of reversible computing blocks with a minimum number of elementary operations with high fidelity are necessary. Therefore, a novel design of multiplexer is proposed in this article, which is composed of only 1-CNOT and 1-Toffoli gates. Moreover, the reduced decomposition of the multiplexer and its identity rule-based optimization for the spin-torque-based n-qubit architecture is discussed. To validate the design, the QISKIT implementation of the novel design in terms of amplitude, probability, and Q-sphere representation is carried out. The results are encouraging to realize the reversible computing involving quantum multiplexer as one of the building blocks.

Abstract

The quantum computing (QC) is emerging as one of the possibilities to replace the conventional computing to meet the complex computing challenges. Quantum gates are based on the quantum mechanical phenomena such as superposition and entanglement. Moreover, there are several ways to realize the reversible full adder representing one of the building blocks of the reversible computing. One of the ways to realize the reversible full adder is by using the controlled V and V+ gates. Spintronics is one of the quantum technologies to realize the reversible computing physically. Therefore, there is need of spin-torque based modelling of controlled V and V+ gates for the quantum computing applications in the reversible computing domain. In this paper, the controlled V and V+ gates are modelled for the spin-torque based qubit architecture through the optimization at elementary single-qubit rotation and two-qubit entanglement level. Therefore, the key innovation or unique contribution is to realize the controlled V and V+ gates by using the minimum number of the elementary operations (single- and two-qubits). Moreover, a quantum full adder (QFA) composed of controlled V and V+ gates, is optimized and realized with the spin-torque models of the controlled V and V+ gates to achieve fault tolerant fidelity. Therefore, the novelty is that the optimization of the controlled V and V+ gates for the reversible full adders is carried out by using the identity rules.

Abstract

Quantum computing (QC) provides an efficient platform to solve complex problems such as number factoring and searching. The quantum Fourier transform (QFT) is an integral part of quantum algorithms for integer number factoring, phase estimation, discrete algorithms, interchange of position and momentum states, quantum key distribution protocol, multiparty quantum telecommunication, and quantum arithmetic. The theoretical and experimental implementations of QFT on various platforms have been proposed by researchers. Spin-torque-based qubit(s) manipulation is one of the encouraging solid-state device technologies. However, to date, QFT is not realized by spin-torque-based QC architecture. In this article, the spin-torque-based architecture has been modeled with the help of optimized decomposition of quantum circuits for the QFT. Moreover, an optimal-depth Clifford + T gates set-based quantum circuit is utilized to implement the QFT. The performance analysis in terms of fidelity (>99%), magnitude, and phase difference of respective density matrices for different forms of three-qubit QFT provides a novel way of its physical realization to address the complex problems.

Abstract

The semiconductor industry is facing a twofold challenge at sub-nanometer level; first, the high power dissipation in irreversible computing architectures due to information loss and second, inability to handle large data due to sequential information processing. These issues create obstacles in producing the presumed low-power complex computing outcomes. The heat dissipation can be reduced by utilizing the complementary metal-oxide-semiconductor-based reversible computing architectures. However, these architectures fail to enhance the performance owing to inability to process large data. Quantum computing (QC) can circumvent these problems due to its fundamental ineffaceable characteristics of quantum mechanics-based reversible computing and parallelism. Spin-torque-based physical realization is the most suitable platform for reversible computing due to the electron spin analogous to the qubit. However, optimal quantum circuits are required to physically realize the complex Boolean logic due to spin-qubit decoherence and reduce the number of transistor switching activities for the spin generation and injection required for the spin-qubit rotation. Therefore, in this paper, optimal quantum circuit decompositions are presented with the help of developed elementary quantum library {R y (θ) , R z (θ) , √SWAP for the spin-torque-based QC architecture. The reversible Boolean logic performance is analyzed and compared for the conventional, reduced, and optimal decompositions on the first- and second-order transmission coefficient matrix-based spin-torque QC architecture. The results encourage to set a path toward QC-based reconfigurable complex computing systems in near future.

Abstract

Spin-torque-based quantum computing (QC) architecture is emerging as one of the novel technologies to meet scalability challenge due to its intra architecture spin qubit state manipulation. The existing model for spin-torque-based QC does not include the ratio of reflection barrier height to exchange interaction to the transmission coefficients. Therefore, in this paper, a modified matrix is proposed to analyze the effect of ratio of reflection barrier height to exchange interaction on electron-qubit interaction, deviation of axis of rotation for single-qubit rotation, and average error probability for two-qubit rotation in a spin-torque-based n-qubit reconfigurable architecture. In addition, the conventional and reduced quantum gates are compared for existing and modified matrices. The quantum gates performance is analyzed in terms of number of electrons required per gate for the electron-qubit interaction, gate fidelity, number of elementary quantum operations per gate, and gate execution time. Reconfigurability is accomplished through barrier height modulation to reduce the architecture hardware. Moreover, a novel nanomagnet-based spin reservoir is incorporated in the architecture for the nonlocal spin injection to facilitate only spin-based operations. High fidelity (~99%) of quantum gates is attained for the fault-tolerant QC.

Abstract

The science of using the electron's spin in electronic devices is popularly known as spintronics. Researchers have been exploring spintronics to achieve nonvolatility, low dynamic power, zero standby power, and high device density. Several novel materials and phenomena have recently been discovered in this field, including the monumental spin-transfer torque (STT) effect. Since then, aggressive research activities have been conducted in both academia and industry in the field of STT-based devices, circuits, and memories. The accomplishments in this field can be revamped to a nonvolatile computing architecture for the future. The purpose of this article is to review the status and prospects of STT-based devices and their circuit implications along with future challenges. Starting with the basic concepts and device physics, advanced applications of STT are discussed. The outlook for cutting-edge technology is provided in terms of novel magnetoresistive devices embodied in the form of magnetic tunnel junctions (MTJs) controlled by the giant spin Hall effect (GSHE ) and an electric field. Moreover, the concepts of all-spin logic (ASL) and MTJ-based logic are discussed. Their circuit implications and associated challenges are also reviewed.

Abstract

The compounds with silver chalcopyrites usually possess excellent electronic properties including functional hole conductivity and robust hybridization (p-d), which further give the direction to scrutinize these compounds to explore their unique behaviour for optoelectronic applications. We used density functional theory (DFT) to investigate the ground state, optical, and phonon properties then implemented SCAPS-1d software to analyse photovoltaic (PV) parameters of AgRhM2 (M = S, Se, Te) compounds. The computed band structures depict semiconducting nature with an indirect band gap within the range of 1.85–0.77 eV. Metal chalcogen overleaping is observed near the valence band maximum (VBM) owing to the robust 3d and 2p hybridization. Calculated phonon dispersion curves (PDC) indicate the dynamical stability of scrutinized AgRhM2 (M = S, Se, Te) compounds. Raman spectra of AgRhM2 (M = S, Se, Te) demonstrate two Eg and A1g modes originating from the perpendicular and the parallel vibrations respectively of the Rh-M atoms. We have calculated the optical constants of the nominee silver based rhodium chalcopyrites, which are lacking particularly in the center of optoelectronic applications. Further, the solar cell parameters such as Voc, Jsc, η (%), and FF, of AgRhM2 have been calculated at various temperature operating conditions.

Abstract

The novel 2D materials (germanene/graphene heterostructure) based pressure sensor has been proposed at nanoscale via theoretical analysis by means of computing the electrical parameters such as energy band gap and electrical conductivity of germanene under the effect of applied tensile stress. The calculation of electrical parameters have been executed utilizing electron-phonon interactions. Germanene is considered on to the substrate of graphene considering compatibility between their mechanical properties. It has been observed that the bandgap exhibits negative magnitudes that leads conducting nature of germanene/graphene composite. The sensitivity of the proposed sensor is found (2.63 – 9) 10-6 KPa-1 for the stress range of 100 KPa to 200 KPa. Moreover, it has also been observed that the proposed sensor has the optimum stress regime up to 9 GPa. The results of the present work pave new directions to design the nanoscale pressure sensor.

Abstract

This article focuses on a polarization measurement method based on Mueller calculus for determining the polarization properties of metal substrates. As the Mueller matrix of a medium provides all its polarization-altering properties, the presented method enables to predict the effect of any optically absorbing media on the polarization state of light beam. For the measurement, a polarized beam of light is reflected off the substrate under study and the change in state of polarization is measured in terms of Stokes parameters. Simple formulae have been derived to deduce the values of matrix elements from the measured Stokes parameters. The presented method facilitates determination of the optical properties of any absorbing medium even though the optical constants are unidentified. It has been validated by the estimation of Mueller matrix elements of a few metal reflectors (Cu, Al and SS304) using Fresnel’s equations and comparing the theoretical values with the experimentally determined values. It has been verified further by measuring the complex refractive index of a sample (brass: Cu–Zn alloy) using the principle angle method and comparing the results with that obtained by newly developed method. For the materials under study, the average absolute error in the measurement of matrix elements is found to be <0.01 and the standard deviation is <0.02. The main advantage of the method is that the polarization properties of any optically absorbing medium can be determined using a simple optical setup at any desired wavelength.

Abstract

The bandgap tuning of two-dimensional (2D) materials is a vital step for their potential applications in the realm of nanoelectronics, optoelectronics, and spintronics. In this context, the bandgap of cobalt (Co)-adsorbed nanoribbons of novel 2D materials (for instance, graphene (GNR), h-BN (BNNR), silicene (SiNR), germanene (GeNR), stanene (SnNR), and phosphorene (PNR)) is investigated under the efect of a transverse magnetic feld via an acoustical deformation potential (ADP) scattering mechanism. Bandgaps ranging from 1.10 eV to 1.42 eV were obtained for Co-adsorbed 2D nanoribbons, which display semiconducting behaviour. In addition to that, investigating the impact of temperature on the bandgap revealed an anomalous temperature dependence of the bandgap. The outcomes of the present work would be advantageous for developing transition metal (TM)-adsorbed-nanoribbon-based nanoelectronic and spintronic devices, wherein controlling their bandgap by employing a magnetic feld is a useful tool for advancing nanoribbon-based technology.

Abstract

Preparing student’s digital marksheet using images of student answer-books is a potential application in academic institutions. Segmenting assigned marks automatically from answer-book images is extremely challenging, and it also demands pre-processing before the recognition stage. In addition, recognizing handwritten digits is crucial due to diferent writing styles. Existing research admits the superior performance of deep learning-based models in handwritten digit recognition (HDR) applications for popular datasets. However, their implication on real-time data for an experimental setup needs much attention. This paper presents an experimental setup that uses student answer-book images to record students’ marks digitally. We proposed a lightweight convolutional neural network (CNN) model for HDR. We also introduced a contour-based segmentation process for automatically extracting student details from answer-book images. The obtained results show the state-of-the-art performance of our proposed CNN model for real-time images. Further, introducing additional pre-processing before recognition signifcantly enhances the accuracy of the HDR experimental setup.

Abstract

The ADITYA upgrade (ADITYA-U), a medium-sized (R0 = 75 cm, a = 25 cm) conventional tokamak facility in India, has been consistently producing experiments findings by using circular and shaped-plasmas. Recognizing the plasma parameters aligning closely with the design parameters of circular limited plasmas, ADITYA-U shifted its focus toward exploring the operational regime for experimentation on saw-tooth and MHD phenomena. Moreover, ADITYA-U has made consistent advancements toward conducting preliminary plasma shaping experiments through the activation of top and bottom divertor coils utilizing hydrogen as well as deuterium fuels. Confinement is improved by a factor of ∼1.5 in D2 plasmas when compared to H2 plasmas of ADITYA-U. Further, ADITYA-U operations emphasize preventing disruptions and runaway electrons (REs) to ensure safe operations for future fusion devices. Significant suppression of REs has been achieved in ADITYA-U with the application of pulsed localized vertical magnetic field (LVF) perturbation, thereby establishing the technique’s independence from the tokamak device. The successful RE mitigation requires a critical threshold of LVF pulse magnitude, which is approximately 1% of the toroidal magnetic field, and a minimum duration of ∼5 ms. Apart from this, several novel findings have been achieved in the ADITYA-U experiments, including the modification of sawtooth duration through gas-puff, the emergence of MHD-induced geodesic acoustic mode-like oscillations, the propagation of fast heat pulses induced by MHD activity, the control of RE dynamics through Gas-puffs, the propagation of pinch-driven cold-pulses, the transport and core accumulations of argon impurities, the mass dependency of plasma toroidal rotation and the detection of ‘RICE’ scaling, as well as the characterization of edge plasma using wall conditioning methods, such as glow discharge cleaning using a combination of Ar-H2 mixture, localized wall cleaning by electron cyclotron resonant plasma, and the development of machine learning-based disruption predictions, will be discussed in this paper.

Abstract

This article presents a comprehensive investigation into the structural, magnetic, and dielectric properties of Ba1− xCoxFe12O19 (x = 0.00, 0.10, 0.20, 0.30, 0.40 and 0.50) prepared at 1100 °C using the heat treatment method. The FTIR analysis revealed the formation of the ferrite phase. XRD analysis provided valuable crystallographic parameters and confirmed the formation of M-type hexaferrites along with a BaFe2O4 phase. TGA investigations elucidated the thermal stability after 600 °C. VSM measurements unveiled the variation in magnetic saturation with cobalt substitutions from 24.390 to 41.629 Am2 kg− 1; coercivity from 1508 to 3577 Oe. Formed samples are magnetically hard in nature. The dielectric measurements indicate that the conduction observed at low frequencies can be attributed to the presence of grain boundaries, while the conduction observed at higher frequencies is mostly influenced by the grains themselves. All samples have a frequency-dependent increase in AC conductivity. These findings contribute to the understanding of its potential applications in the automotive industry, sensors, biomedical applications and related fields.

Abstract

A series of Sr2Cu2PrxFe28-xO46 (x = 0.00 to x = 0.32 with a step of 0.08) hexagonal ferrite was synthesized by the heat treatment method, and heated at 1300 ◦C for 6 h. These samples were characterized using FTIR, XRD, FESEM, VSM, and low-frequency (20 Hz–2 MHz) dielectric measurements. FTIR investigation confirms the ferrite phase formation in all the samples. XRD investigation reveals that all samples possess the X-type as a major phase with a minor M-phase. FESEM images show smaller grain size ranges between 25.27 μm and 51.25 μm. EDX elemental analysis confirms the existence of constituent elements in synthesized materials. VSM analysis shows that prepared ferrites possess a soft magnetic nature, the saturation magnetization of heated samples was found in the range of 35.99 Am2/kg to 49.44 Am2/kg, and coercivity was observed in the range of 10.372 kA/m to 37.443 kA/m. Relaxation peaks have been observed in the loss tangent profile for x = 0.00, 0.08. The Nyquist plot for samples S1 and S2 represents the low-loss universal capacitance circuit, while samples S3 to S5 represent the parallel conductance-capacitance circuit.

Abstract

SrFe12O19 (M-type hexaferrite) and NiFe2O4 (spinel) nano ferrite powders were synthesized in the presence of Calotropis gigantea (crown) flowers extract separately. SrFe12O19/NiFe2O4 nanocomposites were prepared in the presence of crown flowers extract and the effect of different weight ratios (M:S – 9:1, 8:2, 7:3, 6:4, 5:5) on structural, microstructural, magnetic, electrical transport, and dielectric properties were studied. The average crystallite size of nanocomposites was found from 25 nm to 44 nm. In addition, it was observed that the crystallite size of the M-phase decreased when the spinel phase increased. XRD analysis depicts the presence of both M and S phases in composites. The M-H loops analysis of SrFe12O19/NiFe2O4 composites indicates that the coercivity (3181–326 Oe), and saturation magnetization (57.5 Am2/kg. - 40 Am2/kg.) decreased when the spinel phase amount increased. Nanocomposites with weight ratios 9:1, 8:2, 7:3, 6:4 belong to a hard ferrite, while 5:5 shows soft magnetic nature. However, prepared composites possess a multi-domain structure. The weak exchange coupling interactions were found in composites 9:1 and 8:2, whereas the partial exchange coupling interactions were observed in composites 7:3, 6:4, and perfect exchange coupling interaction was noticed in 5:5.

Abstract

Plasma equilibrium in ADITYA/ADITYA-U is provided by two pairs of vertical field coils (BV1 & BV2) placed outside the vessel. A peak loop voltage of ∼20V is required for successful breakdown and start-up in ADITYA, which leads to a higher IP ramp-rate ∼6 - 8 MA/Sec during the first ∼7ms of discharge. To hold the plasma column in equilibrium, the vertical field should also be ramped-up at the same rate. Series connections of vertical field (BV) coils do not provide the required ramp rate due to the high L/R time-constant of the coils and 12 pulse converter firing. Therefore, additional arrangements are made to achieve it. The addition of a precharged capacitor of 500 μF/3 kV with VF converter based power supply allows successful start-up but causes concern about a slight dip that is observed in the plasma current. To obtain proper stabilization, two techniques are used. One is the paralleling of BV coils, and second is using the combination of another capacitor bank of 19.5mF/1.2 kV and IGBT based power supply have improved the plasma performance and raised the IP ∼ 150 kA with dIP/dt ∼ 3.0 - 3.5MA/s in ADITYA. In this paper, the effect of the equilibrium field in accordance with plasma performance is discussed in detail.

Abstract

Since the 2018 IAEA-FEC conference, in addition to expanding the parameter horizons of the ADITYA-U machine, emphasis has been given to dedicated experiments on inductively driven particle injection (IPI) for disruption studies, runaway electron (RE) dynamics and mitigation, plasma rotation reversal, radiative-improved modes using Ne and Ar injection, modulation of magneto–hydrodynamicmodes, edge turbulence using periodic gas puffs and electrode biasing (E-B). Plasma parameters close to the design parameters of circular plasmas with H2 and D2 as fuel have been realized, and the shaped plasma operation has also been initiated. Consistent plasma discharges having IP ∼ 100–210 kA, t ∼ 300–400 ms, ne ∼ 3–6 × 1019 m−3, core Te ∼ 300–500 eV were achieved with a maximum BT of ∼1.5 T. The enhanced plasma parameters are the outcome of repeated cycles of baking (135 ◦C), followed by extensive wall conditioning, which includes pulsed glow discharge cleaning in H, He and Ar–H mixture, and lithiumization. A higher confinement time has been observed in D2 compared to H2 plasmas. Furthermore, shaped plasmas are attempted for the first time in ADITYA-U. A first of its kind inductively driven particle injection for disruption mitigation studies has been developed and operated. The injection of solid particles into the plasma core leads to a fast current quench. Two pulses of electron cyclotron resonance wave at 42 GHz are launched in a single discharge: one pulse is used for pre-ionization and the second for heating. In a novel approach, a positively biased electrode is used to confine REs after discharge termination. E-B is also used for controlling the rotation of drift-tearing modes by changing the plasma rotation. Cold pulse propagation and signatures of detachment are observed during the injection of short gas puffs. A correlation between the plasma toroidal rotation and the total radiated power has been observed with neon gas injection-induced improved confinement modes

XRD analysis shows the development of the M-phase, along with PbM and hematite. The microstructural analysis reveals the stacking clusters of hexagonally shaped platelets. TEM image and SAED pattern of x = 0.3 composition shows polycrystalline nature and formed particles observed to fused with neighbouring particles. M − H loops of all samples reveal hard magnetic behaviour and possess multi-domain structure. The maximum saturation magnetization of 55.427 A m2/kg is observed in x = 0.10 composition and coercivity of prepared hexaferrites was found to vary from 0.058 T to 0.390 T. The cobalt substitution has a strong influence on the dielectric properties of prepared hexaferrites. The value of ac conductivity increases with cobalt substitution from x = 0.00 to x = 0.10, and followed by a reduction from x = 0.10 to x = 0.40. The same trend is observed for the dielectric constant. The low value of loss tangent for all compositions shows apt scope for lossless application.

Abstract

Diversity and combining is one of the robust techniques to mitigate multi-path fading in RF links and turbulence-induced scintillation in FSO links. This article evaluates the effect of different diversity and combining techniques on outage and BER performance of decode and forward RF-FSO link. We have utilized diversity and combining techniques over source to relay RF link and/or relay to destination FSO link. The selection combining, transmit antenna selection, maximal ratio combining, and maximum ratio transmission schemes are considered. The Monte-Carlo simulation results of outage probability and bit error rate are compared by considering different parameters affecting link quality like the strength of atmospheric turbulence, pointing error, FSO link detection scheme, RF link fading strength, diversity order, etc. It is found that configurations like SIMO-SISO, MISO-SISO, SISO-SIMO, and SISO-MISO, where diversity is applied in either source to relay link or relay to destination link, are improving the overall link performance provided that diversity is applied at the link experiencing stronger fading compared to another link. The link configurations SIMO-MISO or MISO-SIMO also improve the link performance and it can achieve BER of 10−5 at less than 15 dB SNR in favourable link conditions.

Abstract

In this work, we have carried out a performance analysis of the Decode and Forward (DF), dual-hop hybrid Radio Frequency-Free Space Optical Communication (RF-(RF/FSO)) link. The Source to Relay (S R) link is considered as an RF link, and Relay to Destination (R D) link is a parallel RF and FSO link. The selection combining technique is employed at the destination. The RF links are modeled by Nakagami-m distribution, and the FSO link is modeled by and Malaga channel model with pointing errors. For the FSO link, both Intensity Modulation/Direct Detection (IM/DD) and Heterodyne detection schemes are considered. The closed form expressions of Probability Distribution Function (PDF), Cumulative Distribution Function (CDF), and Moment Generating Function (MGF) of end-to-end SNR are derived in form of Meijer’s G function. Utilizing the above results, The expressions for outage probability, bit error rate (BER), and ergodic capacity have been obtained. The numerical results are compared for different strengths of fading of RF links, the strength of atmospheric turbulence, the severity of pointing errors, and detection techniques. The numerical results closely match with Monte-Carlo simulations which validate the analytical work. The RF-(RF/FSO) link’s performance is found to be better than the equivalent RF-FSO link. The link (S R or R D ) experiencing the stronger fading dominates the overall link performance.

Abstract

Free space optical communication (FSO) is featured as a solution to the massive demand for large bandwidth and last-mile connectivity. However, the link performance degrades due to atmospheric turbulence. Like RF wireless communi-cation link, the diversity and combining techniques were found effective in FSO link too. This paper compares BER performance of various diversity and combining techniques. We have simulated maximum ratio transmission (MRT) and transmit aperture selection (TAS) technique as transmit diversity scheme. For the receive diversity techniques, we have used selection combining (SC), maximal ratio combining (MRC), and equal gain combining (EGC). We have also considered MIMO configuration and wavelength diversity. These all techniques are compared for various diversity orders and different strengths of atmospheric turbulence. We found that maximum ratio combining and maximum ratio transmission schemes have the best BER performance among all diversity techniques. However, the MRT technique requires additional resources to make CSI information available at the transmitter.

Abstract

Nowadays, FSO is the best choice for last-mile communication due to its high data rate and low complexity. There are many challenges in FSO, like atmospheric turbulence, scintillation, background noise, beam divergence loss, etc. However, to overcome these, we have several mitigation techniques like modulation and coding, diversity, adaptive optics, aperture averaging, and hybrid RF/FSO. The FSO link needs to be compared for different modulation and diversity schemes to check its effectiveness against atmospheric turbulence. This article compares the BER performance of different modulation schemes like BPSK, DBPSK, QPSK, 8-QAM, 8-PSK, binary and quaternary Optical Space Shift Keying (OSSK) in different strengths of atmospheric turbulence considering the Gamma-Gamma channel model. We have also compared diversity and combining schemes like Maximum Ratio Combining (MRC) and Equal Gain Combining (EGC) to overcome the effect of atmospheric turbulence in weak, strong, and moderate turbulence.

Abstract

Atmospheric turbulence is considered as major threat to Free Space Optical (FSO) communication as it causes irradiance and phase fluctuations of the transmitted signal which degrade the performance of FSO system. Wavelength diversity is one of the techniques to mitigate these effects. In this paper, the wavelength diversity technique is applied to FSO system to improve the performance under different turbulence conditions which are modeled using Exponentiated Weibull (EW) channel. In this technique, the data was communicated through 1.55 µm, 1.31 µm, and 0.85 µm carrier wavelengths. Optimal Combining (OC) scheme has been considered to receive the signals at receiver. Mathematical equation for average BER is derived for wavelength diversity based FSO system. Results are obtained for the different link length under different turbulence conditions. The obtained average BER results for different turbulence conditions characterized by EW channel is compared with the published result of average BER for different turbulence which is presented by classical channel model. A comparative BER analysis shows that maximum advantage of wavelength diversity technique is obtained when different turbulence conditions are modeled by EW channel.

Abstract

In many real time scenarios, it becomes necessary to compare complex networks. Graph distances measure the degree of similarity between any two networks. We conjecture that construction of the edge weight matrix of any network should consider the underlying physics of the problem. In addition to that, the selection of eigenvectors chosen for analysis also play an important role in comparing any two networks. In this paper, we explore the most naturally formed networks in various real time applications, such as tracking the transitions of brain states and real time seizure onset detection, and propose a graph distance measure based on the spectral characteristics of the edge weight matrix. We have conducted several experiments to show the efficacy of the proposed graph distance measure. It has an application in comparing any two brain networks while studying brain dynamics. Our results clearly show that the proposed graph distance outperforms the existing graph distances.

Abstract

The visual scrutinization process for detecting epileptic seizures (ictal patterns) is time-consuming and prone to manual errors, which can have serious consequences, including drug abuse and life-threatening situations. To address these challenges, expert systems for automated detection of ictal patterns have been developed, yet feature engineering remains problematic due to variability within and between subjects. Single-objective optimization approaches yield less reliable results. This study proposes a novel expert system using the non-dominated sorting genetic algorithm (NSGA)-II to detect ictal patterns in brain signals. Employing an evolutionary multi-objective optimization (EMO) approach, the classifier minimizes both the number of features and the error rate simultaneously. Input features include statistical features derived from phase space transformations, singular values, and energy values of time–frequency domain wavelet packet transform coefficients. Through evolutionary transfer optimization (ETO), the optimal feature set is determined from training datasets and passed through a generalized regression neural network (GRNN) model for pattern detection of testing datasets. The results demonstrate high accuracy with minimal computation time (<0.5 s), and EMO reduces the feature set matrix by more than half, suggesting reliability for clinical applications. In conclusion, the proposed model offers promising advancements in automating ictal pattern recognition in EEG data, with potential implications for improving epilepsy diagnosis and treatment. Further research is warranted to validate its performance across diverse datasets and investigate potential limitations.

Abstract

How humans recognise faces and objects effortlessly, has become a great point of interest. To understand the underlying process, one of the approaches is to study the facial features, in particular ordinal contrast relations around the eye region, which plays a crucial role in face recognition and perception. Recently the graph-theoretic approaches to electroencephalogram (EEG) analysis are found to be effective in understating the underlying process of human brain while performing various tasks. We have explored this approach in face recognition and perception to know the importance of contrast features around the eye region. We studied functional brain networks, formed using EEG responses, corresponding to four types of visual stimuli with varying contrast relationships: Positive faces, chimeric faces (photo-negated faces, preserving the polarity of contrast relationships around eyes), photo-negated faces and only eyes. We observed the variations in brain networks of each type of stimuli by finding the distribution of graph distances across brain networks of all subjects. Moreover, our statistical analysis shows that positive and chimeric faces are equally easy to recognise in contrast to difficult recognition of negative faces and only eyes.

Abstract

Real-time seizure onset detection has been an active area of research in the study of epilepsy. Electroencephalography (EEG) measurements are widely used in seizure detection due to their high temporal resolution, cost-effective, and noninvasive nature. Various approaches based on machine learning are used for epileptic seizure detection, but these approaches do not explicitly reveal the underlying dynamics, require larger datasets for training, and are computationally demanding. Although high-frequency oscillations (HFOs) are the new biomarkers of epilepsy, they cannot be used with the existing data acquisition systems as they require high sampling rates and high cutoff frequency of the used filters. In this article, we present a novel approach for real-time seizure detection using high spatial frequencies. Since eigenvalues of the graph Laplacian represent spatial frequencies, we conjecture that higher eigenvalues and eigenvectors will contain the detailed information of seizure and non-seizure brain states. Hence, we have formed sub-band characteristic response vector (sub-band CRV) using weighted sum of eigenvectors corresponding to higher spatial frequencies and analyzed it over time. We have used a publicly available dataset to demonstrate the efficacy of the proposed approach. We observed that the proposed approach performs satisfactorily well in real-time automated seizure detection without requiring any kind of prior training. Moreover, our approach is not only accurate in seizure detection but also is independent of sampling rates, hence can be implemented easily in clinical realm for developing an automated seizure detection tool with the existing data acquisition systems operating at low sampling rates.

Abstract

Objective: Classification of the neural activity of the brain is a well known problem in the field of brain computer interface. Machine learning based approaches for classification of brain activities do not reveal the underlying dynamics of the human brain. Methods: Since eigen decomposition has been found useful in a variety of applications, we conjecture that change of brain states would manifest in terms of changes in the invariant spaces spanned by eigen vectors as well as amount of variance along them. Based on this, our first approach is to track the brain state transitions by analysing invariant space variations over time. Whereas, our second approach analyses sub-band characteristic response vector formed using eigen values along with the eigen vectors to capture the dynamics. Result: We have taken two real time EEG datasets to demonstrate the efficacy of proposed approaches. It has been observed that in case of unimodal experiment, invariant spaces explicitly show the transitions of brain states. Whereas sub-band characteristic response vector approach gives better performance in the case of cross-modal conditions. Conclusions: Evolution of invariant spaces along with the eigen values may help in understanding and tracking the brain state transitions. Significance: The proposed approaches can track the activity transitions in real time. They do not require any training dataset.

Abstract

Sparse learning algorithms for system identification differ from their non-sparse counterparts in their improved ability in quickly identifying the zero coefficients in a sparse system. This improvement has been achieved using the principle of zero attraction, whereby the near zero coefficients of the model are forced to zero. In order to further improve the zero attraction capability of sparse adaptive algorithms, an attempt has been made to design a polynomial sparse adaptive algorithm. The enhanced modelling ability of the proposed scheme is evident from the simulation results. The proposed method has also been successfully applied in modelling an acoustic feedback path in a behind the ear digital hearing aid.

Abstract

The primary goal of this study is to enhance the performance of MoS2-based heterostructure solar cells by mitigating the critical influence of lattice mismatch across different surfaces. To surmount this challenge, we have used first-principles computations to calculate and analyse the electrical and structural characteristics to determine the optimal suitability of ZnSe and Zn3P2 as electron and hole transport layers, respectively, which may exhibit minimal lattice mismatch with the MoS2 absorber layer. Band gap analyses have indicated that the nature of the bands influences the proposed configuration; specifically, the electron transport layer (ETL) and absorber are characterised as indirect, whereas the hole transport layer (HTL) is identified as direct within the band structure. Moreover, structural analysis has revealed that ZnSe and Zn3P2 demonstrate remarkably low mismatches of approximately 1.8 % and 14.74 %, respectively, when interfaced with the MoS2 absorber layer, marking the lowest reported data to date, to the best of our knowledge. Accordingly, the configuration Al/FTO/ZnSe/MoS2/Zn3P2/Ni has been strategically designed to alleviate lattice mismatch issues and enhance overall device efficiency. Further, to optimize the device configuration, we have employed the SCAPS-1D tool. Through meticulous simulations using SCAPS-1D, we optimized various parameters, including layer thicknesses, carrier concentrations, bulk defect densities of each layer, interface defects, operating temperature, and parasitic resistance. Notably, our simulations indicate that a MoS2 layer with a thickness of 1 µm and a doping concentration of 1 x 1016 cm−3 yields outstanding results, including a champion efficiency (η) of 32.55 %, open-circuit voltage (Voc) of 1.03 V, short-circuit current (Jsc) of 37.75 mA/cm2, and a fill factor of 83.03 %. These findings were compared with previously reported theoretical and experimental data and found to exhibit superior efficiency in this study, showcasing the potential of our proposed heterostructure design to advance the field of solar cell technology.

Abstract

This study investigates the dimer lines-dependent electrical and mechanical properties of armchair nanoribbons (ANRs) derived from graphene and post-graphene 2D materials. We have developed a general equation based on the number of dimers, rooted in a Pandya-Jha formulation, that uses the tight-binding approximation in conjunction with electron-phonon interaction theory to predict and control important parameters such as bandgap, elastic modulus, surface mass density, and phonon velocity. The observed inverse relationship between dimer lines and bandgap and elastic modulus offers a significant design principle for ANRs, allowing for the precise optimization of these materials for devices requiring electronic functionality and mechanical robustness. The strong correlation between our theoretical predictions, which have been validated against established computational methods (LDA, GW, DFT), and the observed experimental findings demonstrates the practical significance of this dimer-line-based approach. This work establishes a significant framework for accelerating the advancement of ANR-based flexible sensors, NEMS devices, and energy-efficient transistors, thereby enhancing the theoretical foundations and computational facilities available for the emerging field of 2D nanomaterial-based electronics.

Abstract

The impedance spectroscopic (IS) and electrical equivalent circuit analysis of the popular combination indium tin oxide/n-CdS/p-Si heterojunction solar cell is being carried out for the very first time in this analytical study using solar cell capacitance simulator (SCAPS)-1d and the IS module. In this analysis, it is aimed to uncover the device's inherent characteristics for the purpose of future advancements and improvements. Various characteristics and features, as well as the basis for future device improvements, are uncovered through rigorous analysis of the following variables: forward/reverse bias voltage, frequency, illumination intensities (dark and light mode), wavelength-dependent capacitance–voltage, conductance-voltage, capacitance–frequency, and capacitance–temperature. Additionally, spectral response (SR) charts that rely on wavelength are created in addition to Nyquist and Bode plots. The acquired impedance data is much enhanced by these displays. Through IS analysis, a potent method for investigating the dynamics of electrical and ionic charges inside cells is revealed. An improved comprehension of the internal voltage and doping profile in the layers is achieved through additional Mott–Schottky analysis. Bode graphs that rely on frequency provide a better way to comprehend the device's dielectric characteristics. The SR curve can be better understood with the help of these graphs.

Abstract

A silicon heterojunction (SHJ) solar cell with the attractive and widely used atomic layer deposited (ALD)-ZnO/n-CdS/p-Si configuration is examined in this work to learn more about its electrical properties. Using EIS and SCAPS-1D, a comprehensive model of the device is created and then simulated. Theoretical aspects of the cell are examined through the use of similar electrical circuit models, focusing on the transmittance spectrum made possible by the ALD-ZnO layer's low reflectance and high visible transmittance. In this study, the C–V tool is used to study the trap states in the silicon absorber layer under different lighting conditions and wavelengths. The doping concentration and built-in potential are determined using the Mott–Schottky technique. In addition, the cell's properties are investigated by measuring its G–V, G–F, C–T, and C–F in different real-world scenarios. As a means of visualizing the electrochemical impedance data, Nyquist plots—sometimes called Cole–Cole plots—are utilized. By utilizing absolute impedance and phase shifts, Bode plots are employed to examine the system's frequency response. Last, the results of the SHJ cell's spectral response measurements are given, which confirm the results of the Nyquist plots.

Abstract

A transversely applied magnetic field can alter the energy bandgap and other corresponding electrical parameters of a PN-device at the nanoscale. The present theoretical analysis demonstrates that the applied magnetic field controls the bandgap and resistivity of a phosphorene nanoribbon (PNR)-based PN-device. This allows the device to function as a magnetic field sensor as well. For this purpose, the electron–acoustic phonon scattering mechanism is used to estimate phonon-mediated electronic resistivity, which is a parameter directly linked to the bandgap. The armchair configuration of nanoribbons is subjected to energy bandgap and resistivity calculations owing to their semiconducting nature. It is found that in the absence of a magnetic field, the device exhibits a semiconducting nature, but when a magnetic field is supplied, the device acquires a conducting (metallic) state. This semiconductor-to-metal transition is attributable to the change in resistivity of the PN-device under a transversely applied magnetic field, which ultimately results in a change in bandgap. The outcome of the work is pivotal for (i) various nanoelectronic applications that demand semiconductor–metal transition and (ii) designing a magnetic field sensor via bandgap regulation of PNR-based PN-devices.

Abstract

The electronic transport properties of two-dimensional materials are strongly influenced by the charge carrier mobility and the energy bandgap. Furthermore, the carrier-phonon interaction governs the electrical response of any electrical device at a specific temperature. In light of this, the electron mobility and energy bandgap of fluorine (F) doped armchair Boron Nitride nanoribbons (a-BNNRs) are computed theoretically and analysed further. The acoustical deformation potential (ADP) scattering mechanism is taken into account to determine the mobility of the system. The calculations are carried out in presence of an applied electric field as well as different doping concentrations across a specified temperature range (200–300 K). The computed value of electron mobility for F-BNNR is of the order 104 cm2 V−1 s−1. Such higher magnitude of electron mobility suggests the semiconducting nature of BNNRs. Moreover, the variation of electron mobility as a function of temperature and doping concentration demonstrates a significant reduction in the acoustical phonon-limited electron mobility of fluorine-doped boron nitride nanoribbons. To estimate the energy bandgap, a set of equations are determined from the Fermi velocity expression using the nearly free electron (NFE) model. The computed energy bandgap is found to diminish with the increasing size of the nanoribbon. This behaviour of F-doped a-BNNRs envisages its applications in Visible-IR optical sensors.

Abstract

The novel 2D materials (germanene/graphene heterostructure) based pressure sensor has been proposed at nanoscale via theoretical analysis by means of computing the electrical parameters such as energy band gap and electrical conductivity of germanene under the effect of applied tensile stress. The calculation of electrical parameters have been executed utilizing electron-phonon interactions. Germanene is considered on to the substrate of graphene considering compatibility between their mechanical properties. It has been observed that the bandgap exhibits negative magnitudes that leads conducting nature of germanene/graphene composite. The sensitivity of the proposed sensor is found (2.63–9) × 10−6 kPa−1 for the stress range of 100 kPa to 200 kPa. Moreover, it has also been observed that the proposed sensor has the optimum stress regime up to 9 GPa. The results of the present work pave new directions to design the nanoscale pressure sensor.

Abstract

The bandgap tuning of two-dimensional (2D) materials is a vital step for their potential applications in the realm of nanoelectronics, optoelectronics, and spintronics. In this context, the bandgap of cobalt (Co)-adsorbed nanoribbons of novel 2D materials (for instance, graphene (GNR), h-BN (BNNR), silicene (SiNR), germanene (GeNR), stanene (SnNR), and phosphorene (PNR)) is investigated under the effect of a transverse magnetic field via an acoustical deformation potential (ADP) scattering mechanism. Bandgaps ranging from 1.10 eV to 1.42 eV were obtained for Co-adsorbed 2D nanoribbons, which display semiconducting behaviour. In addition to that, investigating the impact of temperature on the bandgap revealed an anomalous temperature dependence of the bandgap. The outcomes of the present work would be advantageous for developing transition metal (TM)-adsorbed-nanoribbon-based nanoelectronic and spintronic devices, wherein controlling their bandgap by employing a magnetic field is a useful tool for advancing nanoribbon-based technology.

Abstract

Carrier scattering rates and transport properties such as electron effective mass and resistivity are calculated for Mn doped armchair graphene (AG) via polar acoustical phonon (piezoelectric) scattering under high electric field and different doping concentrations. It is observed that the electron effective mass reduces with respect to AG on manganese doping. However, in contradiction to this reduction, the electron effective mass increases with the doping concentration. The scattering rate offered by polar acoustical phonons to the electrons is dominant at lower temperatures and significantly reduces with the increase in temperature. The polar acoustical phonon contributed resistivity increases with the rise in electric field at low temperatures.

Abstract

The energy band gap of graphene, h-boron nitride, stanene, silicene, germanene, and phosphorene nanoribbons is investigated theoretically with two approaches. In the first approach, a set of equations to calculate the energy band gap of nanoribbons is deduced using the expression of Fermi velocity. The size dependency of the energy band gap so obtained confirms previous expressions. The second approach, however, determines resistivity by directly connecting quantity to the energy band gap using an electron-acoustical phonon scattering mechanism. For the calculation of the energy band gap and resistivity, the armchair configuration of nanoribbons is considered. It is observed that the transverse magnetic field influences the energy band gap and resistivity. The magnitude of the band gap is negative up to a certain value of the field and turns positive at a sufficiently higher field. The negative band gap can be interpreted as metallic behavior of the materials. The results of the work are useful in the determination of the energy band gap of nanoribbons for their nanoelectronic and optoelectronic applications as well as tuning the band gap using the applied magnetic field.

Abstract

In this paper, multiferroic binary compounds BaTiO3 (BTO) and YFeO3 (YFO) were synthesized by the solid-state reaction method with varying concentration of x from 0 to 1.0 in the step size of 0.25. The prepared binary compounds have undergone the various characterizations like XRD, FTIR, Dielectric spectroscopy, and P–E loop analysis. The XRD of the compounds shows the single-phase structure symmetry varying from orthorhombic to tetragonal as the concentration of BTO increased. The bending and stretching vibration of the bond is confrmed by the FTIR. Dielectric results show the NTCR and non-Debye type relaxation in multiferroic compounds. The temperature-dependent dielectric properties revealed that the phase transition takes place in all the prepared compounds which confirms the ferroelectric nature of the compounds which makes promising application in the field of sensors. The P–E loop results show ferroelectric and leaky behavior of the compounds which have a significant potential in energy storage devices. The paramagnetic behavior of the composites at room temperature (RT) is confirmed by theoretical analysis of the polycrystalline samples.

Abstract

In present article, the polycrystalline composites, BaxY(1-x)TixFe(1-x)O3 (BYTFx), were synthesized through the solid-state reaction method with different concentrations of x. The prepared composites were characterized by XRD, FTIR, SEM and UV–Visible spectroscopy. The crystallographic studies of doping effect of BaTiO3 (BTO) in YFeO3 (YFO) are studied through detailed analysis of XRD data. Scherer and W–H plot analyses have been carried out to estimate the crystallite size and amount of the strain present in the composites. The results of XRD show that unit cell is contracting, and the structural symmetry is varying from orthorhombic to tetragonal in nature on doping of BTO. The surface morphology of the compounds is studied through SEM micrographs. The bond formation and distortions induced by doping are probed through FTIR analysis. The force constant and bond length are estimated through detailed analysis of FTIR data. The obtained results promise us for better dielectric properties of compounds. Band gap of prepared compound is estimated through UV–Vis data analysis. The obtained wide band gap nature as semiconductors makes them suitable as photorefractive materials.

Abstract

The structural and Impedance studies of ferroelectric BiFeO3 (BFO) and paraelectric SrTiO3 (STO) perovskite compounds are reported here. The XRD is performed to confirm the phase formation of prepared samples. The XRD patterns have shown that these materials crystallize and the overall structure remains unaltered with increment in concentration of BiFeO3. Dielectric analysis (Impedance spectroscopy) of the prepared materials shows a normal dielectric behavior like other ceramic compounds and the dielectric constant as well as the dielectric loss of the sample is encouraging for the intermediate composite 0.5BFO+ 0.5STO for end industrial application.

Abstract

In this work, polycrystalline fine powders of xBaTiO3 - (1-x) BiFeO3 (abbreviated in this article as xBTBF, where x = 0, 0.25, 0.5, 0.75 & 1.0; amount of concentration) has been synthesized by Solid State Reaction route (SSR) using extra pure carbonates and oxides. From the XRD analysis BTO and BFO exhibits pure phase structure without any kind of secondary phase while the structure of intermediate compounds has sustained the matrix of BTO and the unit cell of BFO is gradually merged in to BTO. Furthermore, the SEM results show that grains and grain boundaries are clearly visible with few amounts of defects. FTIR spectroscopy is used for estimation of bonds present in the samples. The broad nature of the absorption peak has been explained successfully in the view of distortions which are not evident through XRD. Depending on wave number various physical quantity like effective mass, bond length, frequency of vibration has been determined for Ti-O and Fe-O bonds. The obtained values of bond length have assured the formation of bond between Ti-O and Fe-O. The possibility of enhancement in electrical properties is also discussed in the light of obtained results.

Abstract

The samples of SrTiO3 (STO) doped YFeO3 (YFO) were prepared by solid-state reactions. The crystallographic structural analysis of the prepared samples has been studied. The phases of STO with cubic perovskite symmetry and YFO with tetragonal symmetry were formed. The intermediate samples have sustained the structural symmetry of YFO compound with expansion in the unit cell dimension. The effect of addition of STO on electric performance of YFO material has been investigated in this article. The complex permittivity usually becomes very high due to electrode polarization and carrier transport. Complex impedance, modulus studies indicated the presence of grains and grain boundary contribution, non-Debye type of relaxation of the doped ceramic samples.

Abstract

Protection of data integrity and person identity has been an active research area for many years. Among the techniques investigated, developing multi-modal recognition systems using audio and face signals for people authentication holds a promising future due to its ease of use. A challenge in developing such a multi-modal recognition system is to improve its reliability for a practical application. In this paper, an efficient audio-visual bimodal recognition system which uses Deep Convolution Neural Networks (CNNs) as a primary model architecture. First, two separate Deep CNN models are trained with the help of audio and facial features, respectively. The outputs of these CNN models are then combined/fused to predict the identity of the subject. Implementation details with regard to data fusion are discussed in a great length in the paper. Through experimental verification, the proposed bimodal fusion approach is superior in accuracy performance when compared with any single modal recognition systems and with published results using the same data-set.

Abstract

OFDM (Orthogonal Frequency Division Multiplexing) technique is a multicarrier modulation technique in which data bits are transmitted in parallel over multiple subcarriers. Its main advantage to other techniques lies in its robustness against multipath fading and ISI (Inter Symbol Interference). It has widely gained acceptance and is the integral part of modern high speed systems like Wi-Fi (802.11a), LTE (Long Term evolution), DMT (Discrete Multi-tone Technique) systems, DVB (Digital Video Broadcast) systems. OFDM physical layer is also used for SDR (Software Defined Radio) based applications. In this paper a fast prototype design from concept to implementation of an OFDM system is carried out using Keysight Technologies Tool 'SYSTEMVUE'. The implementation of final design was done in 40 nm CMOS Xilinx Virtex VI XC6VLX760 FPGA. The results obtained were analyzed on LA (Logic Analyzer) and were verified with the simulation results. Using SystemVue's model based FPGA flow rapid prototyping and high gain in design time can be achieved.

Passive source localization using single hydrophone has received considerable attention in the last decade particularly in marine biological studies. If proven successful, it should find tremendous applications, both in military and civilian. Underwater vehicles such as gliders, AUVs, ROVs, torpedoes, mines, etc. seldom have more than one sensor fitted on them for carrying out reconnaissance/threat neutralization operations. Therefore, this paper investigates the usage of a method based on multipath time delays to estimate the slant range between the source and receiver. Time delays estimated theoretically were used to establish the usefulness/limitations of this method. Surface ship's radiated noise signature was subjected to cepstral analysis to estimate time delays between the direct path and the surface reflected path. The time delays thus obtained were used for estimating the slant range between the source and receiver. The comparison between the measured and the estimated time delays was found to be satisfactory.

Abstract

The wideband transceivers like the software defined radio require designing wideband RF hardware covering octave bands. The local oscillator of the mixer should be a wideband frequency synthesizer. Building on the theory of oscillations in the voltage controlled oscillator, the paper reviews the concept of negative resistance in the transistor circuit with some base inductance. It also provides simulation of this concept. To apply the theory and simulation, the actual VCO hardware was designed and fabricated for the range covering 1200 to 2400 MHz. These VCOs were used in the design of wideband PLL frequency synthesizer. The results including very good phase noise performance are presented. This approach can be used to design wideband synthesizers in other RF range.

Abstract

The demand for mobile communication systems with global coverage, interfacing with various standards and protocols, high data rates and improved link quality for a variety of applications has dramatically increased in recent years. The Software-Defined Radio (SDR) is the recent proposal to achieve these. In SDR, new concepts and methods, which can optimally exploit the limited resources, are necessary. One very important requirement of SDR is designing wideband RF hardware covering octave bands. For example, the local oscillator of the mixer should be a wideband voltage controlled oscillator (VCO). The paper presents theoretical concepts for designing VCOs. It also provides simulation of the design. Using this conceptual design and simulation, the actual VCO hardware was designed and fabricated, and the results including very good phase noise performance are presented.

Abstract

The demand for mobile communication systems with global coverage, interfacing with various standards and protocols, high data rates and improved link quality for a variety of applications has dramatically increased in recent years. The Software-Defined Radio (SDR) is the recent proposal to achieve these. In SDR, new concepts and methods, which can optimally exploit the limited resources, are necessary. Multiple antenna system is one of those, which resort to transmit strategies, referred to as Space-Time Codes (STCs). It gives high quality error performance by incorporating spatial and temporal redundancy. The paper discusses the space-time block codes and highlights the trade-off between the number of transmitter and receiver antennas and the bit error rate. We simulate MIMO systems using M-ary Phase Shift Keying (PSK) and compare the results with Single Input Single Output (SISO) systems. This analysis can be helpful in choosing the desired modulation scheme depending upon the Bit error rate (BER) and Signal to noise ratio (SNR) requirements of the service.

Abstract

The Indian test facility (INTF) is a negative hydrogen ion-based 100-kV, 60-A, 5-Hz modulated NBI system having 3-s ON/20-s OFF duty cycle. Prime objective of the facility is to characterize ITER diagnostic neutral beam (DNB) with full specifications, prior to shipment and installation in ITER. The automated and safe operation of the system will require a reliable and rugged instrumentation and control system which provide control, data acquisition (DAQ), safety, and interlock functions, referred as INTF-DACS. The INTF-DACS has been designed based on the ITER CODAC architecture and ITER- plant control design handbook (PCDH) guidelines with the aim of developing the technical understanding of CODAC framework to be utilized for development of plant system instrumentation and control for DNB. Presently, the development work has been initiated for both the control system and DAQ system of INTF DACS. The INTF DAQ system has to perform functions related to acquiring, monitoring, timing synchronization, and archiving of the signals. It also has to interface with the control system of INTF to ensure proper operations. The DAQ system is designed for acquiring over 700 signals for 14 plant systems. The development of this whole system is done in NI LabVIEW using NI real-time PXIe. The PXIe platform with RTOS performs acquisition of signals at sampling rate of up to 10 KS/s. One of the main challenges is to develop the DAQ system to support multichannel triggered-based acquisition and monitoring for pulse durations up to 3600 s. The host layer is a distributed processing system consisting of two hosts and database system. To ensure timing synchronization, a dedicated timing network is included based on IEEE 1588 protocol with help of PXI timing cards. This helps in providing a timing reference to other future systems. For archiving data, MySQL-based data server is integrated for storing data for each experimental shot continuously which can be utilized later for query based data retrieval. In this paper, the development strategy and test results are discussed in order to develop the DAQ system for INTF including the development of interfaces with other components of DACS and experiences obtained, which can be utilized to develop similar DAQ systems of large scale. The novel methods developed for monitoring signals and file size reduction are also discussed.

Abstract

The deep learning has recently pushed the boundaries of computational understanding of the various complex problems which were earlier thought to be unsolved or even not conceived. The challenge arises when implementing such deep neural networks on the limited resource devices. To make them deployable on the embedded/mobile devices with power and compute capability constraint, a lot of techniques has been proposed by the researchers in the academia as well as industry to compress these networks. A transfer-learning-based approach can be used to distil the knowledge gained by higher complexity network and pass it on to the lower complexity network, with minimal or no change to the hyperparameters of the network and without losing the prediction accuracy. This kind of framework is well suited for vision-based application expecting real-world performance from the overall system. As a use case, the pet detection on the Kaggle dataset has been conducted for proving the approach feasibility.

Abstract

Deep neural networks have shown significant success across various applications. To solve the complex problems, the increasing depth and complexity pose the challenges of large computation and storage requirements when deploying such networks on embedded devices with limited storage and power. Many techniques have been developed by researchers to compress the deep neural networks to make them deployable on portable devices by reducing the storage requirements. This paper describes the implementation of deep neural network with teacher student model. A comparatively smaller student model learns the information passed from the larger teacher model without losing the accuracy and its learning/inference rate is also improved. So this kind of framework is suitable for embedded applications deployment where real-time performance is required.

Abstract

This paper proposes a Time-to-Digital Converter (TDC) as an on-chip temperature sensor. An all-digital TDC, with 12-bit coarse and 5-bit fine output bits, has been implemented in 0.18 μm CMOS with a time-resolution of 92.71 ps, time range upto 12.151 μs and power consumption of 353.8 μW. The temperature dependence of the clock period, of ring oscillator in the TDC, has been carried out to develop an analytical model. The proposed analytical model is used to estimate the temperature directly from the digital counts obtained from the TDC. The time to digital conversion achieves a temperature resolution <0.01 C and temperature range C, sampled at 125 KHz frequency. The results of the temperature sensor are first validated with temperature independent inputs to the TDC. Further, a Proportional To Absolute Temperature (PTAT) current reference circuit for time inputs is integrated with the TDC. The PTAT current reference circuit has a 12.21 ppm/C drift in time input with the temperature. The proposed TDC based temperature sensor with current reference circuit -restricts the error within −0.4 C - 1.24 C and compares favourably with the reported literature.

Abstract

In this paper, a power management unit (PMU) with battery backup and output load regulation using switched capacitor converters using 0.18 μm Complimentary Metal Oxide Semiconductor technology is presented. Low power consumption is obtained by employing subthreshold design methods. The main building blocks of the PMU are a voltage regulator, a voltage monitor, a battery backup and switched capacitor (SC) converters. The voltage regulator has an output voltage VOUT at 0.95 V and 0.968 V at input voltages of 0.98 V and 1.33 V, respectively. Perpetual operation at the load side is confirmed by implementing a battery backup module, which provides the battery voltage to the load circuit when the output voltage of the energy harvesting (EH) source is insufficient. The presented PMU consumes 46 nW at 0.98 V and 3.919 μW with SC converters at 1.33 V. Different voltages can be tapped from the PMU from the 3:2, 2:1, 3:1, 4:1 and 5:1 down converters that provide output voltages of 0.67 V, 0.5 V, 0.33 V, 0.25 V and 0.2 V to the load, respectively. The maximum current that can be delivered by the PMU is 1 mA at an input voltage of 1.33 V and is adequate for many low power applications.

Abstract

A power management unit (PMU) with battery extender and output load regulation is presented using 0.18μm CMOS technology. For designing few sub-circuits of the PMU, subthreshold region of MOSFET is utilized, which significantly contributes to achieve low power operation. The proposed PMU consists of a voltage regulator, a voltage monitor, a battery backup module and two DC-DC Switched Capacitor (SC) Converters. The regulator output voltage VOUT is regulated at 0.95 V and 0.968 V at input voltages of 0.98 V and 1.33 V respectively. To ensure continuous operation at the load circuit, a battery extender module is implemented in case of unavailability of EH source. The power consumption of the PMU at input voltages of 0.98 V and 1.33 V is 46nW and 1.567 μW respectively. Near threshold operation is ensured at the load side by further regulating the voltage at the output to 0.67 V and 0.5 V using 3:2 and 2:1 SC Converters respectively. The current consumption of the 3:2 and 2:1 SC Converters is 748 nA and 751 nA respectively. The proposed PMU can deliver output current up to 1 mA at 1.33 V of input voltage and is suitable for numerous applications where low power operation is essential as it consumes a small amount of power.

Abstract

This paper investigates a multiple-input multiple-output dual-hop underwater visible light communication (UWVLC) system with decode and forward (DF) relay, considering turbulence-induced fading and path loss. Our research aims to analyze the performance of this system under weak oceanic turbulence, featuring M laser sources at the transmitter and N detectors at the destination. We model the UWVLC channel using a log-normal distribution and employ one laser diode and one photodetector at the relay. By selecting the optimal laser source and photodetector based on maximum instantaneous signal-to-noise ratio (SNR), we derive the cumulative distribution function (CDF) of the end-to-end SNR. Utilizing this CDF expression, we provide closed-form expressions for outage probability and average symbol error probability (ASEP) using Gauss–Hermite quadrature techniques for the rectangular quadrature amplitude modulation scheme. We analyze ASEP for different constellation points with M sources and N photodetectors and present simulation results demonstrating ASEP versus average SNR, as well as outage probability versus average SNR, showcasing close agreement with analytical predictions. Moreover, we offer insights for system designers by presenting a trade-off between constellation points and the number of lasers, along with the number of photodetectors, to optimize system performance.

Abstract

In this paper, we consider a vertical Underwater Wireless Visible Light Communication (UWVLC) system, where the source is located at the surface of the sea. The distance between both the source and the destination is divided in certain intervals or layers. We assume turbulence in the underwater channel and the intensity of the turbulence, referred in term of scintillation index, varies between consecutive layers. Further, the turbulence based fading channel is modelled by log-normal distribution and the statistics of the channel vary from one layer to another. Thus, we assume cascaded channel with independent but non-identically distributed log-normal distributions. The variance of the channel in each layer is a function of scintillation index of the layer. We assume 32-cross quadrature amplitude modulation (XQAM) scheme and derive closed form expression of Average Symbol Error Probability (ASEP). We analyze the ASEP performance of the system for different layers with different intensities of turbulence. As the number of layers or depth increases, the performance degrades. We also present simulation results of ASEP and compare them with their analytical counterparts. A close matching between both validates our analytical approach. Furthermore, we present the performance with 32-rectangular quadrature amplitude modulation (RQAM) scheme with 16 × 2 and 8 × 4 constellations. We observe that the XQAM outperforms the RQAM.

Abstract

In underwater conditions, visible light communication (VLC) can provide a high data rate of up to Mbps for real-time communication systems. Turbulence-induced fading due to salt and temperature variations in seawater, as well as progressive course loss with distance due to absorption and scattering, are the most common impairments in underwater VLC (UWVLC). We examined the performance of the vertical UWVLC link considering the effect of chlorophyll. First, there is attenuation. It is suggested that a model based on chlorophyll attention exists. It can be seen that the chlorophyll fluctuation has a significant impact on the attenuation profile, which reaches its peak when the chlorophyll attention is highest. We also reduced the path loss caused by chlorophyll at a wavelength of 530 nm. A more thorough examination was also carried out to compare the performance of the links when laser and LED resources are used.

Abstract

Visible light communication (VLC) has the ability to provide a high data rate up to Mbps in underwater environments for real-time communication systems. In underwater VLC (UWVLC), two major impairments are the turbulence-induced fading due to variation of salt and temperature of seawater and incremental path loss with distance due to absorption and scattering. We consider these two impairments and derive the closed form expressions for average symbol error probability (ASEP), asymptotic relative diversity order, and ergodic capacity for UWVLC dual-hop cooperative communication system. We consider multiple receiver branches with selection combining to combat the effect of fading. The impact of temperature on the fading parameters and system performance is highlighted. We conduct a comparative analysis of ASEP for four-pulse amplitude modulation and four-square quadrature amplitude modulation schemes and draw useful insights. We prove the accuracy of the derived analytical expression using

Abstract

Machine learning (ML) is a sub-branch of artificial intelligence (AI) that employs statistical, optimization, and fuzzy techniques to learn from past data and detect patterns from large, noisy, and complex datasets. Oral cancer treatment for a patient with mouth or throat cancer is crucial. Oral cancer treatment analyses the development of cancer cells in the tissues of the mouth or throat post-operation. In post-operation care, the mouth opening of the patient depends on the surgery performed. Further, how often should the patient perform the exercise with a jaw stretcher machine and consult the doctor? In this paper, we employed different machine learning algorithms to predict the treatment plan for the patient. We introduced the one-way ANOVA test to identify the optimal feature set. Our proposed approach applies different ML algorithms with ten-fold cross-validations to suggest a post-operation treatment plan for a patient. The experimental results show the highest accuracy with the polynomial regression and the hybrid approach.

Abstract

In multimedia devices such as mobile phones, surveillance cameras, and web cameras, image sensors have limited spatial resolution. As a result, the image captured from these devices misses high-frequency content and exhibits visual artifacts. Image super-resolution (SR) algorithms can minimize these artifacts by reconstructing missing high-frequency textures. Image SR algorithm estimates a high resolution (HR) image from a given low-resolution (LR) image. Given a single LR image, reconstructing an HR image makes SR be an extremely ill-posed problem. Over the past decade, dictionary learning-based methods have shown promising results in SR reconstruction. These methods extract numerous patches from external images for training dictionaries via sparse representation. However, these methods do not involve any patch selection mechanism that enhances the learning process. This paper proposes a dictionary learning-based SR algorithm that extracts selective patches from an input LR image based on the iScore criterion. Results show that patch selection criteria keep only 36% of all extracted patches for training while improving the peak signal-to-noise ratio (PSNR). Furthermore, we have proposed a method to initialize dictionaries to achieve better convergence that enhances PSNR.

Abstract

Single Image Super-Resolution (SISR) through sparse representation has received much attention in the past decade due to significant development in sparse coding algorithms. However, recovering high-frequency textures is a major bottleneck of existing SISR algorithms. Considering this, dictionary learning approaches are to be utilized to extract high-frequency textures which improve SISR performance significantly. In this paper, we have proposed the SISR algorithm through sparse representation which involves learning of Low Resolution (LR) and High Resolution (HR) dictionaries simultaneously from the training set. The idea of training coupled dictionaries preserves correlation between HR and LR patches to enhance the Super-resolved image. To demonstrate the effectiveness of the proposed algorithm, a visual comparison is made with popular SISR algorithms and also quantified through quality metrics. The proposed algorithm outperforms compared to existing SISR algorithms qualitatively and quantitatively as shown in experimental results. Furthermore, the performance of our algorithm is remarkable for a smaller training set which involves lesser computational complexity. Therefore, the proposed approach is proven to be superior based upon visual comparisons and quality metrics and have noticeable results at reduced computational complexity.

Abstract

Image Super-Resolution (SR) is an ill-posed problem with an objective of constructing High Resolution (HR) image from given Low Resolution (LR) image. The existing popular SR approaches include deep neural networks which require large dataset for training and also they are computationally expensive. In this paper, a novel algorithm to achieve SR which utilizes examples taken from LR itself for training have been proposed. The proposed algorithm fastens the training process via selectively fetched examples (patches) from given LR image. For the training purpose, Simultaneous Codeword Optimization (SIMCO) based dictionary learning algorithm is used along-with Least Absolute Shrinkage and Selection Operator (LASSO) for sparse representation. The trained dictionary is further utilized for constructing an HR image. Experimental results show that the proposed algorithm outperforms in terms of computational complexity and quantitative measures also with respect to deep learning algorithms.

Abstract

Image fusion methods are required when images from the same or different sensors are available. In several applications, photographs from a colour camera are often fused with thermal infrared (medium-wave or long-wave) images. This paper focuses on those applications (typically security and surveillance) wherein the fused images are used by a human operator who will, in turn, make critical decisions. This paper presents two frameworks for fusing colour and infrared images, one in the red-green-blue (RGB) colour space and the other in lightness-chroma-hue (LCH) colour space. We compare qualitatively and quantitatively the performance of five existing fusion methods that work best in this scenario. The study is carried out across two datasets. Quantitatively, four existing metrics are used to analyse the performance. In addition, this paper proposes a performance metric that appeals to human perception and measures how well colour, edge, and contrast information are transferred to the fused image.

Abstract

The rapidly increasing requirements from context-aware gadgets, like smartphones and intelligent wearable devices, along with applications such as audio archiving, have given a fillip to the research in the field of Acoustic Scene Classification (ASC). The Detection and Classification of Acoustic Scenes and Events (DCASE) challenges have seen systems addressing the problem of ASC from different directions. Some of them could achieve better results than the Mel Frequency Cepstral Coefficients – Gaussian Mixture Model (MFCC-GMM) baseline system. However, a collective decision from all participating systems was found to surpass the accuracy obtained by each system. The simultaneous use of various approaches can exploit the discriminating information in a better way for audio collected from different environments covering audible-frequency range in varying degrees. In this work, we show that the frame-level statistics of some well-known spectral features when fed to Support Vector Machine (SVM) classifier individually, are able to outperform the baseline system of DCASE challenges. Furthermore, we analyzed different methods of combining these features, and also of combining information from two channels when the data is in binaural format. The proposed approach resulted in around 17% and 9% relative improvement in accuracy with respect to the baseline system on the development and evaluation dataset, respectively, from DCASE 2016 ASC task.

Abstract

M-type, Ba0.4Pb0.6Fe12-xCoxO19 (x = 0.00, 0.10, 0.20, 0.30, 0.40) hexaferrites, synthesized using citrate gel auto combustion method, and heated at 950 °C, 4 h for lossless applications. XRD analysis shows the development of the M-phase, along with PbM and hematite. The microstructural analysis reveals the stacking clusters of hexagonally shaped platelets. TEM image and SAED pattern of x = 0.3 composition shows polycrystalline nature and formed particles observed to fused with neighbouring particles. M − H loops of all samples reveal hard magnetic behaviour and possess multi-domain structure. The maximum saturation magnetization of 55.427 A m2/kg is observed in x = 0.10 composition and coercivity of prepared hexaferrites was found to vary from 0.058 T to 0.390 T. The cobalt substitution has a strong influence on the dielectric properties of prepared hexaferrites. The value of ac conductivity increases with cobalt substitution from x = 0.00 to x = 0.10, and followed by a reduction from x = 0.10 to x = 0.40. The same trend is observed for the dielectric constant. The low value of loss tangent for all compositions shows apt scope for lossless application.

Abstract

Cooperative non-orthogonal multiple access (C-NOMA) is one of the promising techniques which improves the connectivity and transmission rates between nodes. In this paper, we consider using C-NOMA in a system model with a source S and two sets of users, MR and MD . Every user in MD has a direct link (DL) to S , while for users in MR , there is no DL. We employ two C-NOMA schemes - Half-Duplex NOMA (HD-NOMA) and Improved-Virtual-Full-duplex NOMA (I-VFD-NOMA) - which serve users in MR with cooperation from users in MD . We consider two scenarios, A and B, where in A, the inter-user channels are assumed unknown, while in B, they are assumed known. Based on |MR| and |MD| , we employ combination/one of the two schemes to provide connectivity to users in MR . In order to do so, under scenarios A and B, we propose user pairing schemes to pair users within MD and also pair users between MR and MD . Considering average sum rate (ASR) for users as the metric, we perform Monte-Carlo simulations to evaluate the proposed schemes. Although HD-NOMA and I-VFD-NOMA are key enablers for the system model under study, both suffer from imperfect successive interference cancellation (I-SIC). Additionally, I-VFD-NOMA suffers from residual inter-user interference (R-IUI). Hence, through simulations, we study the impact of I-SIC and R-IUI on ASR as well.

In this paper, we introduce an improved performance of well-known lossy data compression techniques, namely Huffman and Arithmetic coding, using a customized scheme that involves threshold selection and conditional pixel probability mapping. The scheme shows efficiency in terms of compressibility with minimal information and similarity loss in the process. In addition to this, flexibility is exhibited by the proposed scheme to select required compression using a threshold. The outcomes of the research are evaluated and compared based on a variety of parameters such as compression ratio, MSE, SSIM, and PSNR. The proposed approach is capable of effectively handling information-varying images of different quality levels.

Abstract

Studied a virtual full-duplex (VFD) non-orthogonal-multiple-access (NOMA) system in which a source S transmits one message each to users R 1 and R 2 , and two messages to a destination D, in three time slots. In conventional VFD-NOMA, S follows a fixed sequence of transmission (SoT) for the messages of users and destination, leading to a higher outage probability (OP) at R 2 and D, and a higher overall system OP (O-OP). To this end, a novel transmission scheme is proposed which significantly decreases the OP at R 2 and D, and the O-OP. All the wireless links undergo Nakagami- m fading, and S only knows the instantaneous channel state information (CSI) of S-R 1 and S-R 2 links. It is assumed that users suffer from imperfect successive interference cancellation (I-SIC) and residual inter-user interference (R-IUI).

Abstract

Device to Device communication has been considered as a popular issue for small cell networks. In this paper, a Sum Rate Priority Iterative Auction scheme is proposed to improve the spectral efficiency of mobile peer-to-peer communication for downlink cellular network. For spectral efficiency, first allocation of spectrum to various cellular and d2d devices is done by Reverse-iterative combinatorial auction mechanism, in which the cellular devices laced with spectral bandwidth bid for d2d devices iteratively. Optimization of spectrum is done by plotting sum-rate over SINR, number of cellular devices and number of d2d users. In addition, we compare the results obtained in Reverse Iterative combinatorial Auction (R-ICA) method with Sum Rate Priority Iterative Auction method by plotting the obtained spectral efficiency against the number of D2D users.

Abstract

In this paper, detailed design of Chess Clock using a Finite State Machine (FSM) is presented. The chess clock design is realized through both Field-Programmable Gate Array (FPGA) and Application-Specific Integrated Circuit (ASIC) flows. This work outlines the complete design process from system conception in Verilog HDL to the final GDS II layout. The FPGA implementation was carried out using Xilinx ISE tool while the ASIC flow was achieved with Cadence design tools, culminating in the generation of a GDS-II file. Through rigorous simulation, synthesis, and optimization, we demonstrated the functionality and efficiency of the Chess Clock FSM. Along with the FPGA and GDSII (layout) implementation, the performance parameters of both are compared in this paper.

Abstract

Considering the scaling limitations of current Complementary Metal Oxide Semiconductor (CMOS) technology, Quantum-dot-Cellular Automata (QCA) is emerging as one of the alternatives. QCA being at the molecular scale, defects are more likely to occur in it. Therefore, substantial development of QCA-oriented defects, its corresponding fault models and test generation is required. In this paper, a test generation algorithm for a QCA combinational circuit is proposed. The FAN (A Fanout Oriented) test generation algorithm is extended for QCA. The proposed Automatic Test Pattern Generator (ATPG) for QCA targets Single Stuck at Fault (SSF) set produced by novel Multiple Missing Cells (MMC) defects. The proposed ATPG is based on the QCA-oriented test generation properties and guided by proposed testability measures.

Abstract

Complementary Metal Oxide Semiconductor (CMOS) technology has been ruling the semiconductor since last five decades. Scaling of CMOS is well proven. CMOS technology may face the scaling problems if it goes beyond the limit. Therefore, there has to be alternate technology to the CMOS technology to achieve designs with low power and less delay. Carbon Nanotube Field Effect Transistor (CNTFET) technology is useful for the implementation of low power and less delay designs. Memory is an integral part of any design. In this paper, CNTFET based SRAM is implemented and compared with CMOS technology. Both are implemented in Cadence Virtuoso using 45 nm technology node. The CNFET cell libraries provided by Stanford University are incorporated in Cadence Virtuoso. This paper presents the complete process of integrating CNFET libraries in Cadence Virtuoso. Further, CMOS and CNFET based SRAM using 45 nm technology are implemented. The performance parameter power and delay of both the technologies are compared.

Abstract

The biggest hurdle in today’s processors is heat dissipation. Complementary Metal Oxide Semiconductor (CMOS) is used currently. In CMOS, irreversible computational occurs which leads to heat and energy dissipation. One of the solutions is to use reversible logic. In this paper, a single-bit comparator design is proposed. The device-level implementation of a reversible comparator using Quantum dot Cellular Automata (QCA) is proposed. The design is made using reversible Fredkin and Feynman gates. These are implemented using QCA. Further, the 1-bit magnitude comparator comprised of Feynman and Fredkin gates is designed. In this paper, the device-level reversible logic implementation and energy calculations are claimed although the performance parameters are not that optimized.

Quantum-dot cellular automata (QCA) is an emerging computational paradigm which can overcome scaling limitations of the existing complementary metal oxide semiconductor (CMOS) technology. The existence of defects cannot be ignored, considering the fabrication of QCA devices at the molecular level where it could alter the functionality. Therefore, defects in QCA devices need to be analyzed. So far, the simulation-based displacement defect analysis has been presented in the literature, which results in an increased demand in the corresponding mathematical model. In this paper, the displacement defect analysis of the QCA main primitive, majority voter (MV), is presented and carried out both in simulation and mathematics, where the kink energy based mathematical model is applied. The results demonstrate that this model can also be valid for the displacement defect in QCA MV.

Abstract

Present silicon technology, Complementary Metal Oxide Semiconductor (CMOS) will face the scaling limitations in near future. The alternate to this technology is Quantum-dot Cellular Automata (QCA) which can overcome the limitations of CMOS technology. Synthesis is the important and compulsory process in design flow. Well-developed open source and commercial synthesis tools are available for CMOS technology. There is need to develop the synthesis tool for emerging QCA nanotechnology. Therefore, in this paper, synthesis algorithm for QCA nanotechnology is proposed. The algorithm is based on pre optimization of logic and developed in Python language. The proposed synthesis algorithm uses Quine-McCluskey technique for optimization and handles up to n-variable functions. It is tested on Microelectronic Centre for North Carolina (MCNC) benchmark circuits and thirteen standard functions.

Abstract

Quantum-dot cellular automata (QCA) are based on the nanoscale and used as an alternative for Complementary Metal Oxide (CMOS) semiconductor technology. The main feature that attracts researchers in the VLSI domain of QCA is the ultra-dense structures with less power consumption and fewer transistors count. This paper presents a low energy dissipation 1-bit magnitude comparator using modified MV32 gates with minimum area. The simulation results of the proposed design have a value of 2.05 meV as total energy dissipation and 0.198 meV as average energy dissipation per cycle. Being at the nanoscale, the possibility of defects must be explored and analyzed. Therefore, the single missing cell analysis for the MV32 gate is carried out and presented in this paper. The hardware description language model is developed to analyze the faults caused by the single missing cell defects in the MV32 gate. At last, the proposed comparator is analyzed under the single missing cell defect to prove its fault tolerance.

In the last four decades, Complementary Metal Oxide Semiconductor (CMOS) technology has achieved circuits and system with features like low power, high device density and high speed. But, heat dissipation issue affects the speed and performance in the computing. Reversible logic based circuits can overcome the problem of heat dissipation and improve the efficiency circuit and system. One of the viable implementations of reversible logic is Quantum-dot Cellular Automata (QCA) nanotechnology. Due to nano scale, occurrence of defect are present in QCA. Therefore, defect must be analyzed in QCA based circuits. In this paper, combinational circuit, adder and substractor based on reversible logic is proposed. The proposed circuit is implemented using QCA devices Majority Voter (MV) and inverter. Further, the fault caused by multiple missing cells defect are analyzed.

Being at molecular scale, defects are more likely to occur in QCA devices. Therefore, the substantial development of QCA-oriented defects, its corresponding fault models and test generation is required. This paper addresses the fault model caused by multiple missing cells defect and test generation for these faults for QCA circuits. We have shown that the single missing cell considerations are not enough. Correspondingly, in this paper, testing properties for the detection of fault caused by multiple missing cell defects in QCA devices mainly Majority Voter (MV) are proposed. Even though there are many advanced ATPGs available for CMOS technology, to demonstrate very special MV-based properties with reference to the test pattern generation process and to open the path for advanced combinational and sequential ATPGs specific to MV-based QCA circuits, the extension of basic Automatic Test Pattern Generator is proposed here. The proposed test generation algorithm is guided by the extended Sandia Controllability Observability Analysis Program (SCOAP) testability measures especially for QCA logic primitives.

Abstract

Quantum-dot-Cellular Automata (QCA) is coming up as the viable technology which may replace existing CMOS technology. In this context, Electronic Design Automation (EDA) tools for design and fabrication like simulation, synthesis, testing etc. are essential. After design entry and behavioral simulation, the synthesis tool is used to convert the behavioral level description into gate level description. The synthesized circuit can be later on used for functional and timing verification, test development and further layout level synthesis. Even though, few QCA synthesis methods are available in the literature, there is lack of simple QCA synthesis method which uses commonly available CMOS based EDA tools as far as possible and hence, less costly. Therefore, in this paper, a simple but novel synthesis method for combinational QCA circuit "QSynthesizer" is proposed. The authors do neither claim an optimized method of synthesis nor a very high level of research in the field of QCA synthesis tool development. Still, this paper definitely contains a frugal innovation for synthesizing QCA circuit in absence of rarely available, low cost QCA synthesizers. The proposed synthesis method comprises logic reduction algorithm implemented in C++, Perl scripts and widely used synthesis tools like Leonardo Spectrum for digital design. The results on Microelectronics Centre of North Carolina (MCNC) benchmark circuits using proposed QSynthesizer show the effectiveness of the proposed method

Abstract

Deep learning has revolutionized communication systems by introducing innovative approaches to address channel impairments through end-to-end models. Autoencoders, a type of deep learning architecture, are adept at learning compact data representations. However, conventional autoencoders in endto- end models can suffer from overfitting, which limits their effectiveness in noisy communication environments. To address this issue, we propose a Sparse Autoencoder-based (SAE) model that enforces sparsity and promotes the extraction of robust features. Despite its effectiveness, the SAE model may still lack the ability to focus on the most relevant features of the input data. To overcome this limitation, we further introduce an Attention Mechanism-based Sparse Autoencoder (ASA) model. This model integrates the feature extraction capabilities of a sparse autoencoder with an attention mechanism that selectively highlights informative features of the signal. Through simulations, we demonstrate that both proposed models significantly improve M-PSK and M-QAM communication system performance. When trained at 7 dB, both proposed models exhibit significant performance improvements at higher testing average SNRs. Our results show that the SAE model outperforms the conventional Maximum Likelihood Detection (MLD) model and baseline autoencoder systems but suffers from error floor issues. The SAE model suffers from an error floor at average SNRs beyond 16 dB for BPSK and 14 dB for higher-order modulation schemes. As the value of M increases, the performance gap between the MLD and the proposed SAE model narrows. The ASA model, however, effectively mitigates the error floor observed in the SAE model for all values of M and across all modulation schemes. This research highlights the benefits of integrating an attention mechanism with SAE, resulting in enhanced robustness and reliability in communication systems characterized by improved accuracy and reduced error rates.

Abstract

The endmember extraction is a challenging problem in spectral unmixing (SU) of a mixed pixel in hyperspectral imagery. There are plenty of attempts to solve the endmember extraction problem. Still, the pure pixel assumption-based algorithms have probably been used most in solving the endmember extraction of SU due to the light computational burden. These pure pixel assumption-based algorithms usually follow one of the criteria: (1) Maximum simplex volume or (2) Extreme projection on a subspace. We propose a novel integrated framework that uses both the criteria mentioned above and the proposed one is referred to as the Convexity-based Pure Index (CPI) algorithm. The CPI generates a fixed number of convex sets based on the number of available bands in the hyperspectral image. The algorithm defines the purity score based on the availability of pixels in the convex sets for the two-band data. The CPI has been compared with contemporary algorithms such as Automatic Target Generation Process (ATGP), Vertex Component Analysis (VCA), Pixel Purity Index (PPI), Successive Volume MAXimization (SVMAX), Alternating Volume MAXimization (AVMAX), TRIple-P: P-norm based Pure Pixel identification (TRIP), Successive Decoupled Volume Max-Min (SDVMM), Negative ABundance-Oriented (NABO), and Entropy-based Convex Set Optimization (ECSO). The metrics, Spectral Angle Distance (SAD) and Spectral Information Divergence (SID) used in the comparison were improved up to 5.9% and 9% , respectively. The CPI outperforms prevailing algorithms on real benchmark data and new AVIRIS-NG data. The robustness of the CPI is also tested for various noisy synthetic data. The efficacy of the proposed algorithm is also tested by using qualitative analysis by visualizing the spectra comparison, and abundance maps for all real data.

Abstract

This paper investigates a multiple-input multiple-output dual-hop underwater visible light communication (UWVLC) system with decode and forward (DF) relay, considering turbulence-induced fading and path loss. Our research aims to analyze the performance of this system under weak oceanic turbulence, featuring M laser sources at the transmitter and N detectors at the destination. We model the UWVLC channel using a log-normal distribution and employ one laser diode and one photodetector at the relay. By selecting the optimal laser source and photodetector based on maximum instantaneous signal-to-noise ratio (SNR), we derive the cumulative distribution function (CDF) of the end-to-end SNR. Utilizing this CDF expression, we provide closed-form expressions for outage probability and average symbol error probability (ASEP) using Gauss–Hermite quadrature techniques for the rectangular quadrature amplitude modulation scheme. We analyze ASEP for different constellation points with M sources and N photodetectors and present simulation results demonstrating ASEP versus average SNR, as well as outage probability versus average SNR, showcasing close agreement with analytical predictions. Moreover, we offer insights for system designers by presenting a trade-off between constellation points and the number of la

Abstract

In this paper, we consider cooperative horizontal and vertical underwater visible light communication (UWVLC) systems employing best relay selection. In the vertical UWVLC system, the source is placed at the sea surface and the destination is placed at a depth of 60 m. The link between the source and the destination is modeled as concatenated layers considering inhomogeneous environmental conditions. The underwater parameters change with depth, causing a variable refractive index, which leads to non-uniform optical turbulence. The horizontal communication link is analyzed for two different levels of turbulence at 10 m and 50 m depths. Turbulence is modeled using a log-normal distribution, whose statistical parameters depend on the temperature and salinity at different depths. We have also taken into account the path losses caused by absorption and scattering, and carried out a comprehensive performance comparison between the horizontal and the vertical UWVLC systems. Insights show that compared to horizontal links, vertical links need an extra relay in order to achieve the same level of matching performance. Moreover, it is shown that the horizontal system’s outage performance improves with depth.

Abstract

Hyperspectral imaging plays a significant role in crop classification and aims to separate various crop pixels from the imagery. It aids the government in deciding agricultural policies. However, high spectral dimensions in hyperspectral data require high computing power and time. This paper presents a new band selection method based on spectral information divergence and correlation (SIDCorrL), which selects optimum bands to classify the crops. The SIDCorrL requires only single ground-truth pixels having the least spectral information divergence value to select the bands. This method requires not only minimum ground truth data but also gives reduced computational complexity. We have evaluated the proposed method on three hyperspectral datasets, AVIRIS-NG, Indian Pines and Salinas. We have used overall accuracy and kappa coefficient as performance parameters from the support vector machine and k-nearest neighbours classifiers. The experimental findings reveal that the proposed band selection method achieves maximum overall accuracy of about 84.79% for Indian Pines and 93.08% for Salinas dataset. The proposed methodology exhibits an improvement in overall accuracy when the number of selected bands ranges from 35 to 50 when compared with the other competitive band selection approaches.

Abstract

This paper proposes a cooperative spectrum sensing (CSS) scheme based on the modified correlation detection (MCD) in an additive Laplacian noise environment. In MCD, the received signal at the cognitive terminal correlates with the primary user (PU) signal. The received signal is then raised to an arbitrary exponent P where 0 < P ≤ 2. At all the values of P except P = 1, the MCD operates as a non-linear detection scheme. For the special case of MCD at P =1, the considered detection scheme follows linear behaviour and it is known as Matched Filter (MF) detection scheme. Using MCD and MF at the cognitive terminal, hard decisions are forwarded to the centralized controlling centre known as fusion centre (FC). Then, they are combined according to standard fusion rules of cooperative spectrum sensing (CSS) scheme such as the ‘OR’ rule, the ‘AND’ rule and the ‘majority rule’, respectively denoted as CSS:OR, CSS:AND and CSS:majority. Finally, the FC decides the presence of the PU. Here, the analytical expressions are obtained for estimating the detection probability and false alarm probability and present the same in form of receiver operating characteristics. The proposed analytical results are corroborated by a close match between simulation results and analytical findings. The proposed results are then compared with the existing detection scheme called soft-limiting PCA (SL-PCA). The proposed research study finally concludes that for a broad range of average signal-to-noise ratio (SNR) indicated by γ, i.e., −20 ≤ γ ≤ 10 dB, the detection performance of CSS:OR fusion scheme outperforms the performance of other CSS:majority and CSS:AND fusion schemes. In addition to this, this study also concludes that the performance of CSS:OR and CSS:majority fusion schemes based on MCD and MF detectors outperform the same based on SL-PCA detection scheme. Conventional schemes refer to the detection schemes in non-cooperative scenario where only one CR exists. As a result, the CSS:majority rule outperforms the conventional detection schemes MCD and MF beyond γ = −12 dB and γ = −11 dB, respectively.

Abstract

Spatial Modulation (SM) is a technology that incorporates digital modulation and coding with multiple antennas to achieve high data rates along with improved energy efficiency. Quadrature spatial modulation (QSM), which extends the transmitted signals to in-phase and quadrature domains, has recently been proposed to improve spectral efficiency (SE) for SM. In this paper, we have considered a combination of Generalized QSM (GQSM) and Quasi Orthogonal Space Time Block Codes (QOSTBC). We propose a new detection scheme for the GQSM and use three different prevailing detection schemes for QOSTBC. We present Bit Error Rate (BER) versus average SNR performance for the combined system using M-QAM constellations with quasi-static spatially uncorrelated Rayleigh fading channels and computational complexity in terms of numbers of addition/multiplication and search time. We have compared the considered system with prevailing GQSM system and shown that the prevailing system, as per active antenna permutation (AAP) in GQSM, offers number of transmitted bits ranging from 2 to 9 whereas the proposed system offers number of transmitted bits ranging from 6 to 16 in the same bandwidth. Thus, there is a visible gain in SE. Furthermore, we have compared the BER performance of the considered system with the performance of maximum likelihood detector (MLD) and spatial modulation (SM). In the considered system, the QOSTBC improves the diversity gain. Hence, we have shown that the considered Scheme 3 substantially outperforms the SM. Further, the considered system with Scheme 3 has nearly similar BER performance with the maximum likelihood detector (MLD), which has higher computational complexity.

In underwater VLC (UWVLC), two major impairments are the turbulence-induced fading due to variation of salt and temperature of seawater and incremental path loss with distance due to absorption and scattering. We consider these two impairments and derive the closed form expressions for average symbol error probability (ASEP), asymptotic relative diversity order, and ergodic capacity for UWVLC dual-hop cooperative communication system. We consider multiple receiver branches with selection combining to combat the effect of fading. The impact of temperature on the fading parameters and system performance is highlighted.We conduct a comparative analysis of ASEP for four-pulse amplitude modulation and four-square quadrature amplitude modulation schemes and draw useful insights. We prove the accuracy of the derived analytical expression using Monte Carlo simulations.

Abstract

Due to the low spatial resolution of the sensor, multiple scattering and intimate mixing at the ground, the majority of the pixels in the hyperspectral image are of mixed type. In this case, spectral unmixing is used to decompose this mixing effect. From the literature, it is clear that non-linear unmixing is more accurate and robust compared to linear unmixing. In this paper, we take a Mangalore dataset captured using Airborne Visible/ Infrared Imaging Spectrometer-Next Generation (AVIRIS-NG) camera to compare various non-linear unmixing. The paper presents and extensive comparison of various endmember extraction algorithms and abundance estimation algorithms. The performance of algorithms was assessed using two quality metrics (Spectral Angle Mapper and Reconstruction Error). Three types of experiments were carried out; endmember extraction accuracy assessment, testing of abundance estimation efficacy and comparison of linear and non-linear models. The simulation results conclude that Energy-based Convex Set (ECS) and Polynomial PostNonlinear Model (PPNM) give accurate results on the considered study site for endmember extraction and abundance estimation respectively.
