Due to the diversity of defocus blurred images, causing the unsatisfied effect of sharpness enhancement of the defocused and blurred image. On this basis, the paper has proposed an enhancement algorithm of defocused and blurred image base on non-local constraints. The estimated results similar to the original image was acquired, the actual defocus blur optical transfer function was calculated and the low inverter over-amplifying the noise was avoided through the improvement of inverse filtering by the Wiener filter. Based on the symmetry of a defocused and blurred circular, the diffusion curve of straight marginal function was filtered and restored to eliminate the noise in the image. On this basis, the non-local self-similarity and total variational regularity of the defocused and blurred image were complemented, and the sharpness of the defocused and blurred image was finally enhanced by using the non-local model to restore the marginal and detailed texture information of the defocused and blurred image. The results of the simulation have shown that the proposed method could not only increase the computational efficiency, but also obtain satisfactory sharpness enhancement of the defocused and blurred image, and a better retain effect of the marginal information.

Advanced numerical simulations, that include modal and frequency response function finite element analysis, frequency domain and time domain finite element method – boundary element method analysis, are performed to study the vibro-acoustic behaviour of crash and splash musical cymbals. The results of the modal analysis agree well with experimental measurements found in literature. The frequency domain and time domain coupled finite – boundary element method simulations, despite their high computational resources and time demands, are used for the crucial comparison of the velocity spectrograms on the cymbal to the radiated sound pressure spectrograms in the air. The computational analysis results show that the splash cymbal is characterized by a faster decay and a higher frequency content compared to the crash cymbal. The advanced multiphysics vibro-acoustic simulations that correlate the displacements and velocities of the vibrated structure with the radiated sound pressure results demonstrate the future capability to synthesize the sounds of cymbal music instruments.

This paper presents a novel access to develop a class-F power amplifier with high power-added efficiency (PAE). The main goal of the proposed PA is to obtain high PAE. The proposed HCC consists a design of output matching circuit (OMN) and input matching combined with a symmetric low-pass filter (LPF) reported. To accomplish a high-efficiency performance, a low-voltage pHEMT in the circuit was executed to supply the required dc-supply voltage. It yielded nth harmonic suppression and high-power added efficiency (PAE). The simulation was carried out using harmonic balance analysis. The power amplifier proposed in this study was fabricated at fundamental frequency of 1 GHz with PAE of 80% and DE of 86% under 12.3dBm input power and very low drain voltage of 2 V. This class-F PA manufactured with such features can be utilized for power amplification in wireless transmitter communication systems.

Volumes of research have been written about problem solving, which is one of the most important components of the human cognition that affects our lives for ages. In this work soft sets are used as means for obtaining a qualitative assessment of problem solving skills and of Case-Based Reasoning systems’ performance. The concept of soft set is a generalization of Zadeh’s fuzzy sets introduced by Molodstov in 1999 as a new mathematical tool for dealing with the existing in real world uncertainty in a parametric manner.

OP-AMPs find applications in different domains of electronics engineering including communications. There have been several OP-AMP configurations realized in the last decades for different target applications. But with the evolution of communication standards, to meet the demand for high data rate over the years, the requirement for a high frequency and high BW OP-AMP is gaining attention. This makes the design challenge much higher. This paper presents a two-stage CMOS amplifier that uses a frequency compensation method to facilitate higher BW. Different parameters like Gain, Gain bandwidth product (GBWP), Phase Margin, and Total Power dissipation are considered in this design. A step-by-step procedure for an efficient amplifier design is followed using frequency compensation. We have achieved a gain-bandwidth product (GBWP) of 110 MHz that is capable of driving large capacitive loads. It also achieves 77.7 dB gain and phase margin of 60° with the minimal noise of 2.27 μ^V/√ Hz and the slew rate of 20.12 V/ms

In view of the COVID-19 pandemic, the exponential increase in the COVID-19 patients is leading to the enormous demand on the healthcare systems across the world. The allocation of resources towards the detection of the people affected by the virus plays a key role in curbing the pandemic and slowing down the spread of the virus to a greater extent. While traditional procedures are utilized to discover COVID-19 individuals, testing each individual with a limited number of testing kits is a massive undertaking. Most healthcare systems include X-ray equipment, and most of them being digitized, can be utilized as a way of screening for COVID-19 patients. This paper proposes AI model that can analyze and predict a possible COVID-19 patient, which can be used to prioritize the people for further testing. Further we propose the automation of this process where the models can be deployed in a remote server or an edge computing device where the X-ray images can be screened by the deep learning model to give predictions with very less turnaround time.

For bearings-only tracking (BOT), there are mainly two problems of nonlinear filtering and poor range observability. In the paper, a new distributed multisensor pseudolinear Kalman filter (PLKF) algorithm is proposed. The sensors use an instrumental vector PLKF (IV-PLKF) to process the measurements of the target independently, which can tackle the bias arising from the correlation between the measurement vector and pseudolinear noise by the bias compensation PLKF (BC-PLKF). The IV-PLKF embeds the recursive instrumental vector estimation method into the BC-PLKF, uses it to construct the instrumental vector, and applies the method of selective angle measurement to modify the local target state estimation and covariance. In the fusion center, the target state can be estimated by using the multisensor optimal information fusion criterion. Then the Cramer-Rao lower bound (CRLB) of multisensor BOT is derived. Simulation results show the effectiveness of the algorithm.

In this paper, a high-speed optical subtractor has been designed and simulated. This circuit is based on a photonic crystal structure with silicon rods embracing a circular cross-section in the air platform. This structure was performed based on the photonic band gap. The best performance of this subtractor is in the highly-usable telecommunication wavelength of 1550, laying in the range of the photonic band gap of this structure. To design the circuit, two inputs with optical sources and two outputs have been used for difference and borrow bit. The features of this logic half subtractor encompassed simple structure, small dimensions, and appropriate level of the outputs 1 and 0.

Yu and Cao proposed “Cryptography based on delayed chaotic neural networks” in 2006. However, in 2009, Yang et al. pointed out the Yu-Cao scheme can not against chosen plaintext attack. Liu et al. studies exclusiveor logical operation very well, and provided Boolean algebra proofs in 2012. Ye et al. used Liu et al.’s method to reinterpret and analyze Yu-Cao scheme in 2018. In this paper the authors would like to give a formal verification by Galois field expression on the exclusive-or operation problem again. As this result, it makes more effective insecure to Yu-Cao algorithm.
