This paper introduces a novel approach for a system-wide performance evaluation of Zigbee networks, in the context of large-scale lighting applications. It allows a comprehensive assessment of Zigbee networks through quantitative measurement of three key performance indicators: Reliability, Robustness, and Responsiveness. It proposes a systematic framework that injects different traffic scenarios into the network to get performance scores for each node in the network for every scenario. These scores are then passed through weighted scoring algorithms to obtain a network-level score for each performance indicator. Weighting factors are computed through the Analytic Hierarchy Process (AHP) that prioritizes multiple criteria based on merit. The framework has been deployed and tested in real-life lighting systems, considering two luminaire network topologies: open-space and corridor layouts. The results show the use of the framework for overall acceptance testing as well as identifying low-performing nodes. Thus, this paper presents a distinctive methodology and a testbed to qualitatively monitor the performance of any Zigbee network deployed for lighting solutions based on user needs. © 2024 IEEE.

The concept of hybrid switch (HyS) by paralleling low-switching-Ioss silicon carbide (SiC) MOSFETs and low-cost silicon (Si) IGBTs offers an improved performance and cost tradeoff in motor control unit (MCU) for electric vehicles (EVs). In this paper, the loss and thermal models are developed for the proposed HyS. Based on that, a multi-objective method is proposed to select the optimal ratio for the HyS. Reliability of Hybrid Switch for EV s under active short circuit (ASC) operating condition is verified by Simulation. Furthermore, both EV model is developed to evaluate the performance/cost of HyS with endurance mileage under China light-duty vehicle test cycle (CLTC) profile. Several challenges of developing HyS are also discussed. It is found that the combination of 1 SiC MOSFET and 3 IGBTs and DIODEs is the low-cost scheme with optimized junction temperatures, while the scheme with 2 SiC MOSFETs and 2 IGBT and DIODEs is the one with the highest efficiency. The HyS with the high-efficiency ratio has a 4.7% increase in endurance mileage compared with IGBT. © 2024 IEEE.

The swift evolution of technology demands a highly efficient system with seamless integration of components. Evolution of system on Chip (SOC) has modified making use of different components within a single chip. Therefore, it becomes very crucial to manage these components. The Advanced Microcontroller Bus Architecture (AMBA) bus architecture, a standard SOC interconnection, enhance Intellectual Property (IP) core reusability and streamlines data transmission. Advanced High-Performance Bus (AHB) is part of AMBA family used for High-speed data transfer communication protocol manages with high bandwidth components like processor or memory. Advanced Peripheral Bus (APB) is specifically used for connecting with low bandwidth components like keyboard and mouse. Thus, the importance of AHB2APB bridge becomes very vital. It is the backbone of all data transfer that takes place within a SOC.

Artificial intelligence technologies provide a newapproach for the real-time transient stability assessment (TSA)of large-scale power systems. In this paper, we propose a datadriven transient stability assessment model (DTSA) that combinesdifferent AI algorithms. A pre-AI based on the time-delay neuralnetwork is designed to locate the dominant buses for installingthe phase measurement units (PMUs) and reducing the datadimension. A post-AI is designed based on the bidirectionallong-short-term memory network to generate an accurate TSAwith sparse PUM sampling. An online self-check function of theonline TSA’s validity when the power system changes is furtheradded by comparing the results of the pre-AI and the *** IEEE 39-bus system and the 300-bus AC/DC hybrid systemestablished by referring to China’s existing power system areadopted to verify the proposed method. Results indicate that theproposed method can effectively reduce the computation costswith ensured TSA accuracy as well as provide feedback forits applicability. The DTSA provides new insights for properlyintegrating varied AI algorithms to solve practical problems inmodern power systems.

The demand for renewable energy has led to a rapid increase in the production and installation of solar photovoltaic (PV) systems worldwide. However, during transportation, installation, and exposure to adverse weather conditions, PV panels are prone to defects that reduce their lifespan and efficiency. Visual and I-V curve test inspection methods are commonly used to maintain the smooth operation of PV systems, but they are limited by the inability to detect most flaws, the need for expertise, and long inspection times. Hence, there is a need for cost-effective and efficient inspection methods to identify defects in solar panels. The objective of this paper is to analyze and compare the benefits and effectiveness of two solar PV inspection methods, namely thermal infrared (IR) imaging and electroluminescence (EL) imaging. Indoor and outdoor IR images are captured using a FLIR Pro thermal camera and EL images are captured using a low-cost converted Panasonic GF3 camera. The results of our study demonstrate that while each method has its advantages, EL imaging is the most effective method for detecting a wide variety of solar cell defects. Thermal IR imaging is useful for detecting defects that affect the temperature of the panel but may not detect minute defects such as microcracks. The simplicity and low-cost nature of the developed EL setup make it a viable option for small and large PV systems, contributing to the advancement of the solar PV inspection field. © 2023 IEEE.

This work presents an adaptive tracking guidance method for robotic fishes. The scheme enables robots to suppress external interference and eliminate motion jitter. An adaptive integral surge line-of-sight guidance rule is designed to eliminate dynamics interference and sideslip issues. Limited-time yaw and surge speed observers are reported to fit disturbance variables in the model. The approximation values can compensate for the system's control input and improve the robots' tracking ***, this work develops a terminal sliding mode controller and third-order differential processor to determine the rotational torque and reduce the robots' run jitter. Then, Lyapunov's theory proves the uniform ultimate boundedness of the proposed method. Simulation and physical experiments confirm that the technology improves the tracking error convergence speed and stability of robotic fishes.

Vibration or ripple reduction is a common topic in motion control, electrical systems, and motor drives. Although wave model-based vibration suppression is novel, the control structures must be systematized. Thus, this study addresses the comparative analysis of control structures derived from the wave model. The primary contribution is to discuss the similarities and differences between an integral-proportional controller and a proportional controller with a disturbance observer through analyses of their transfer function and experimental verification. © 2024 The Institute of electrical Engineers of Japan.

A novel endfire antenna utilizing spoof surface plasmon polaritons (SSPP) and a traveling-wave feeding mechanism is introduced. The proposed endfire antenna operates in the millimeter-wave (mmW) band. The placement of a Vivaldi antenna at the front end of the SSPP endfire antenna allows for the efficient transmission of surface waves and the generation of an end-fire beam. The electromagnetic waves are coupled from the travelingwave feeding mechanism to the slot located between the Vivaldi antenna and the SSPP endfire antenna. Furthermore, we conducted a comparison between the effects of a standing-wave feeding mechanism and a traveling-wave feeding mechanism on the transmission performance and radiation pattern of the designed endfire antennas. The numerical analysis demonstrates that employing a traveling-wave feeding mechanism leads to a reduction of 63% in impedance bandwidth, while concurrently increasing the gain by 0.42dB. The ultimate configured antenna aperture measures 0.21λ0 × 0.02λ0, showcasing its low-profile attributes. © 2024 IEEE.
