When taking pictures in extremely dark light, the image taken is usually very dark and noisy due to the small amount of light entering, and there is clear distortion of color. Since the method of using multi-frame or long-exposure has limitations, we use the single-frame denoising method based on residual dense network (RDN), which uses residual dense block (RDB) to makes full use of local features. Our method has achieved better results than state-of-the-art methods. In addition, we have applied the trained model without fine-tuning on photos captured by different cameras and have obtained similar end-to-end enhancements.

The conductivity of the TFT-LCD circuit can be determined by counting and locating anisotropic conductive film (ACF) particles in the circuit, which is a critical step for the detection of conductivity in the TFT-LCD manufacturing process. In order to solve the aggregation and overlap problems of ACF particles, in this paper, we propose a U-shaped multi-scale convolution network(U-MultiNet). The U-Net network structure is designed adaptively, which reduces the parameter amount of the network. The multi-scale convolution blocks are introduced for extracting the multiscale spatial features. In addition, the particles detection is transformed into a segmentation task, which helps to solve the aggregation and overlap problems of particles. The experimental results show that the method achieves high precision and recall rate, which is far superior to the previous methods.

A new thyristor-based delay element for physical unclonable function (PUF) design is proposed in this paper. Thyristor-based delay element as PUF cell shows strong sensitivity to process variation and is little sensitive to supply voltage and temperature variations, which could effectively improve the uniqueness and stability of PUF design. Simulated results show that thyristor-based delay element has 12.5964 largest standard deviation of delay time over process variation, and 0.4766/1.0631 lowest standard deviation of delay time with respect to temperature variation from -$50^{circ }mathrm {C}$ to $100^{circ }mathrm {C}$, and supply voltage variation from 1.5V to 2.1V, compared with other delay elements.

With CMOS transistors’ scaling showing signs of saturation, an exploration of new working principles suitable for emerging microelectronic devices accelerates. The electron spin is attractive for new device applications as a complement and a possible replacement of the electron charge currently employed by CMOS. The electron spin displays the two well-defined projections on an axis and is thus suitable for digital applications. In magnetic tunnel junctions (MTJs) the free magnetic layer possesses two orientations relative to the fixed layer: parallel and antiparallel. As the parallel and antiparallel magnetization configurations are characterized by different resistances, the thereby stored information can be read. MTJs enable a spin-based type of non-volatile magnetoresistive memory. MTJs are fabricated with a CMOS-friendly process and are quite CMOS compatible. The relative magnetization configuration can be written by means of a spin-transfer torque (STT) or a spin-orbit torque (SOT) acting on the free layer. The torques are caused by spin-polarized electrical currents and not by a magnetic field. Electrically addressable non-volatile magnetoresistive memories are attractive for stand-alone and embedded applications. The state-of-the art concepts of STT and SOT memory, in particular the required modeling approaches, are reviewed, with a particular focus on a fast external magnetic field free switching in advanced SOT-MRAM.

The rapid detection and identification of products based on computer vision has important applications in the fields of unmanned retail and goods sorting. At present, the recognition rate of traditional product identification methods is not high, and the deep learning recognition method requires large-scale training and cannot meet real-time requirements. This paper proposes a product identification algorithm that combines traditional HOG detection with the SIFT feature-based bag of words model for the needs of product identification. Compared with the traditional product identification method for feature matching, the algorithm has the advantages of higher recognition rate and shorter time. The test results show that the real-time recognition rate can reach 98%. At the same time, the algorithm has the advantages of light weight and easy portability, and can be applied to many occasions such as unmanned retail or express picking.

This paper presents a compact model of mutual inductance between two planar inductors on the same plane, which is essential to design and optimize multiple output isolated power supply or multi-channel digital isolators. The proposed model considers the influence of shapes, geometric parameters and relative lateral distances of the inductors, and it is derived by solving Neumann’s integral. Different planar inductors are simulated by 3-D electromagnetic(EM) software and fabricated on a printed circuit board (PCB) or silicon wafer. The proposed model shows good agreement with simulation and measurement results.

Premature ventricular contraction (PVC) is a widespread condition of arrhythmia that can be life-threatening at any time. Fast and accurate use of computers to diagnose PVC is critical for both doctors and patients. In this paper, we propose a new method for PVC detection based on abnormal eigenvalues and decision tree. We choose composite areas, amplitudes and intervals as feature parameters to identify heartbeat types. The method was tested in the published MITBIH arrhythmia database with accuracy, sensitivity and specificity of 99.6%, 97.3% and 99.5%, respectively. The effectiveness of the proposed method is proved by comparison with other methods.

Alarms are the symptom of faults and indicate an abnormal of the communication networks. The Bayesian network is one of the most powerful and popular fault analysis tools. In this paper, we present the alarm prognosis method based on Bayesian inference in order to estimate the health state and trend of the network given by an alarm take as evidence enters the network. The approach reduces human intervention and enhances the availability of the work effectively. Finally, experimental results verify the validity of the approach.

One of the basic applications of television is to give entertainment via cable. Cable companies provide their customers the channels that are broadcasted locally or internationally. Digital Cable TV is fast growing nowadays, but not all companies are ready to adapt to this technology. Analog transmission of cable is still available, however, it is prone to illicit tapping. This study was conducted to detect illicit connections on CATV (Cable Television) lines particularly on analog transmission of signal. The system was conducted on a laboratory scale setup. There was a miniature type CATV distribution line wherein there was a connection from the device to the line. If the system detects illicit connection, then it notifies the user via mobile application. The functionality test was performed to evaluate and validate if the system conforms to its desired tasks. The functions of the system under the evaluation test were a) detection of illicit connection, b) sending of data via Bluetooth and c) receiving of data of the mobile phone. Analysis of the data revealed that the system operated with its desired functions. The results of this study indicate that the developed system was reliable on its functions particularly on detecting illicit connections.
