As power electronics technology continues to advance, the prevalence of switching quantity interface circuits has grown in diverse domains, encompassing industrial production and everyday civilian applications. An analysis of operational data from these circuits, along with an assessment of their overall health, proves instrumental in the timely detection and resolution of operational anomalies. This holds paramount significance in upholding the reliability of these interface circuits. Nevertheless, tracking the degradation trajectory of the core components during their operational lifespan poses a challenge. Typically, only two states, normal and abnormal, are readily discernible, making direct health assessment elusive. To address this issue, this study introduces a health assessment methodology for the fundamental components of switch quantity interface circuits based on active excitation testing. Through the application of active excitation, the performance decay profile of the optical coupler is ascertained, solving the problem of capturing the degradation process within these circuits. This approach facilitates the stable and precise characterization of the health status of switching quantity interface circuits. The health assessment method presented in this paper is characterized by modest computational resource demands and a reduced reliance on expert knowledge. It is adept at quantitatively delineating the health status of switch-quantity interface circuits with precision, thereby offering guidance for the maintenance and replacement of pivotal electronic components within these circuits. In doing so, it contributes to the assurance of operational dependability and an extension of the service life of switch quantity interface circuits.

Almost every part of the economy relies on the transportation industry. The road transportation sector is one of the numerous types of transport sectors. As a vehicle's continual use causes damage, inefficiency, and faults in numerous parts, etc. Timely maintenance prevents or fixes these issues. Aiming at the requirements of vehicle health monitoring, this article studies and designs the cloud computing collaborative vehicle health monitoring network system and proposes the allocation of data transmission paths with an ant colony algorithm as the core. On this basis, it studies the construction of autonomous vehicle health status detection systems based on cloud and fog collaborative computing and gives the system level composition and system framework scheme. In the system, data is collected by sensor equipment and then transmitted, stored, and comprehensively processed. The obtained data provides a technical basis for automobile health detection. Through the construction of a simulation environment, it shows that the algorithm can adjust to the dynamic features of cloud system networks in the environment of road strength construction. The ant colony optimization (ACO) algorithm is a type of probabilistic algorithm that determines the best route through a graph. As compared with the shortest path first (SPF) algorithm and the brute force (BF) storm algorithm in terms of average throughput and response time, it is more suitable for cloud and fog collaborative network transmission environments.

In this paper, the probabilistic-constrained tracking control issue is investigated for a class of time-varying nonlinear stochastic systems with sensor saturation and limited bandwidth in a unified framework in this paper. The saturation of sensors is quantified by a sector-bounded-based function satisfying certain conditions. To gain more efficient utilization of communication channels, a Round-Robin (RR) protocol is utilized to orchestrate the transmission order of measurements. The main purposes of this study aim to design an observer-based tracking controller to achieve the following goals: (1) the related performance indicators of the estimation error is less than given bound at each time step;and (2) the violation probability of the tracking error confined in a certain region is supposed to be higher than a prescribed value and the region is minimized at each instant. In order to reach these purposes, a set of recursive linear matrix inequalities (RLMIs) are developed to estimate the state and design the tracking controller at the same time. Finally, a simulation is exploited to illustrate the availability and flexibility of the proposed scheme. © 2021 Chinese Automation and computing Society in the UK-CACSUK.

The availability of number of open-source hacking tools over the internet and many hacking tools in-built with the Kali Linux operating system led to easy understanding and performing hacking by individuals. Even though, hacking the Wi-Fi passwords is considered a tedious task with open-source tools, they can be hacked easily with phishing. Phishing involves tricking the users with malicious emails and obtaining sensitive information from them. This paper describes the different wireless security protocols and tools for hacking wireless networks. A python script is developed which can be sent as phishing to get all the SSID's and passwords to which the system has been connected. The script has been executed and the results are presented. © 2021 IEEE.

Facial recognition technology is based on a person's facial features. It is often the core of applications such as biometrics, access control, and forensics. However, due to environmental factors such as dust accumulation on the camera lens or equipment failure, the accuracy of the system is often questioned; especially when it comes to noise and partial occlusions in the test images. This paper proposes a new approach for automatic face recognition using histogram oriented gradient features of facial images with auto-associative memory in the form of a “Multi-Connection Hopfield Neural Network”. The method described here efficiently stores and retrieves facial patterns in noisy or partially occluded environments. In testing, this proposed approach achieved a recognition rate of 98.5% on the ORL dataset, outperforming these other state-of-the-art methods. Furthermore, this method maintains 95.0% accuracy even with 50% random noise and exhibits superior performance and robustness under partial occlusion and variable lighting conditions.

international Future Energy Electronics conference (IFEEC)

作者： Shizuna Oshima Hirotaka Koizumi Dept. of Electrical Engineering Tokyo University of Science Tokyo Japan

This paper proposes a new voltage equalizer based on a load-independent class E2 parallel resonant DC-DC converter. This circuit has a characteristic of equalizing the voltages between two battery modules without any control. It also maintains Zero-Voltage Switching (ZVS) throughout the entire equalization operation. Therefore, high-frequency operation can be realized, which enables immediate operation of equalization and downsizing of the circuit. Furthermore, since both modules are isolated by capacitors, the circuit is lighter and less expensive than transformer-isolated circuits. This paper describes the bidirectional operation of the load-independent class E2 parallel resonant DC-DC converter and its principle using equivalent circuit transformations. In addition, simulations and experiments have been conducted for voltage equalization between two modules consisting of 10 cells. As a result, voltage equalization without additional control and ZVS over the entire operation have been confirmed.

In the traditional droop control, the VSG algorithm and the voltage compensation link are added to make the inverter have the large inertia characteristic of the synchronous generator (SG). The output voltage of each parallel inverter is the same, and the active and reactive power are distributed according to the rated capacity ratio. Through the design of the voltage current control loop, the equivalent output impedance of the inverter is inductive, so as to meet the droop control requirements. It is proved that the parallel inverter has good dynamic and static characteristics. Matlab/Simulink simulation and experiment verify the feasibility of the proposed control strategy. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2021.

The problem of two-state reliability redundancy allocation (RAP) is studied. The subsystem is k-out-of-n: G system. Each subsystem is not allowed to mix components (that is, each subsystem chooses one type of component from several kinds of heterogeneous components and only one type of component). Each component in each class has a fixed weight and price, and the k value of each subsystem is fixed. The problem is to determine the type and quantity of the selected components (redundancy) so that the reliability of the system can be maximized under the constraints of the total price and weight given by the system. A new encoding method of solution is constructed, and symmetrical bit transformation technology is used to generate a new solution. On this basis, a new discrete particle swarm optimization (PSO) algorithm is constructed, which uses fixed compression coefficient, dynamic inertia weight and composite iteration technology (i.e. for particles that do not meet the constraints of the system, the second iteration formula is used to generate new velocity and position values). The new algorithm is used to solve the FYFFE problem and the generalized FYFFE problem (33), and the optimal solutions are obtained, which are consistent with the results obtained by the dynamic programming method and substitution constraint method respectively. The new PSO algorithm is easy to understand in theory, easy to implement in programming, and can effectively solve the RAP problem studied. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Today, with more and more devices in the industrial control system (ICS), the risk becomes higher and brings more attack surfaces. The need for reliable anomaly detection systems is increasing. Traditional SCADA-based detection systems deployed are difficult to assess large-scale control systems accurately, and novel AI-based technologies struggle to ensure timely response. In this paper, we propose an edge computing assisted delay-aware anomaly detection (ECADA) scheme for ICS, which considers both the accuracy and timeliness, and ensures that abnormal conditions can be accurately detected and handled in a short time. First, we model the components in ICS as three layers, taking network resources, delay, and reliability into consideration. Second, we convert the anomaly detection procedure into a decision making problem. By dividing the warning capabilities into various levels, the flexibility of the anomaly detection system is enhanced. Third, we cast a mixed-integer linear programming (MILP) problem to find the efficient anomaly detection mechanism, so that it can be dynamically scheduled to achieve the tradeoff between reliability and timeliness. We use an real-world industrial system dataset for experimental evaluation. By comparing with various traditional anomaly detection methods, it is proved that ECADA can always ensure reliable response of anomaly detection system in various network environments.

The use of biometric data, such as various anatomical and behavioural attributes in automatic identification and authentication systems for access control, surveillance, computer security, and law enforcement are increasing. Several nations are already or will soon begin to use biometric technology. In this paper, there is a in detail analysis of innovative biometric systems and also the research study of how the computational techniques used intelligent data system in order to analyse biometric system, The efficacy of biometric technologies will depend on how well they work. Biometric system evaluation examines how well biometric systems adapt to particular characteristics. Planning and carrying out biometric tests are frequently handled by an impartial third party. A measure of confidence in the validity of the claim might be one of the options the algorithm offers. Applications that validate a user's address or confirm their identity at the point of sale are examples of verification applications.
