This paper describes a modified SPICE-compatible VDMOS transistor model that includes NBT and self-heating effects. A complete circuit diagram of the transistor is given, which includes the electrical part of the circuit that models the NBT effect and the equivalent thermal part of the circuit that models the self-heating effect. The parameters of the model were determined based on the technical documentation and the fitting method based on the performed experiments. Fresh transistors and NBT-stressed transistors, with and without a heatsink in the load-driving circuit, were considered. The results of experiments and simulations correspond to each other with a maximum deviation of up to 10%. The proposed model can be used in the design and analysis of transistor reliability parameters.

At many times we observed disturbances of traffic flow on highways. This may be caused by traffic accidents, bad weather conditions, road maintenance or rush hours. The Road Traffic Management takes many rules and regulation, to make road sections more robust to disturbances and improve the recovery from disturbances in traffic flow (traffic resilience). To study the effect and impact of these rules and regulations assessment models of traffic resilience was needed. In this paper, we designed and tested such an assessment model. The model is inspired by the well-known Resilience Triangle. The assessment of traffic resilience was based on measurements of the speed of traffic flow on highways. Neural Networks were used to model and smooth recorded speed data. The Traffic Resilience model has been tested on real life data. © 2023 Owner/Author.

Advancing memory circuitry has heightened the performance criteria for memory in diverse chip applications. Decoders, serving as peripheral circuits to memory devices, have be a prominent area of academic interest. The new NAND/NOR gate circuits are proposed using pass-transistor logic (PTL) and transmission gate logic (TGL). The two hybrid-logic design schemes of high-performance and low-power (HPLP) and HPLP inverting (HPLPI) utilizing PTL and TGL gate in combination with static CMOS logic for decoders are proposed, while achieving fewer transistors, faster speed, lower power dissipation as compared to conventional circuits. Experiments are conducted in TSMC 7nm FinFET process for hybrid-logic decoders. The simulation results indicate that, in comparison to conventional decoders, the proposed hybrid-logic 3-8 decoder demonstrates improvements, with the HPLP design reducing delay by over 19% and power by over 71%, and the HPLPI design reducing delay by over 17% and power by over 48%. © 2024 IEEE.

This research presents an automatic system for the detection of stop line violations. Stop line violation is defined as a condition in which a vehicle does not appropriately stop behind a stop line. This research uses the Histogram of Oriented Gradients (HOG) as feature extractor and Support Vector Machine (SVM) as classifier. We tested our system using a self-made dataset, containing images taken from a traffic CCTV camera. This dataset consists of three sub-datasets for different conditions: photos taken in the morning, afternoon, and evening. Our experiments show that the proposed system achieves accuracy rates of approximately 94.2%, 98.1%, and 95.9%, respectively, for the morning, afternoon, and evening sub-datasets (using HOG cell size of 16x16, linear kernel SVM and k-fold validation with $k$ =10). Therefore, the average accuracy rate is 96.07%. The system is also shown not to be severely affected when the photos are taken during a rainy condition, yielding an average accuracy of 95.3%. Finally, when the system is tested using new data (i.e., those not involved in the k-fold validation experiments) an average accuracy of 98.7% can be achieved. These results show that the proposed system performs well and that the combination of HOG and SVM shows good potential for application in automatic detection of stop line violations. © 2022 IEEE.

Physical-layer security (PLS) is a new paradigm for secure communication without requiring secret key exchange and management. Moreover, PLS with frequency diverse subarray (FDSA) can better control information leakage in the angle-range domain, which mitigates the security weakness of the phased array caused by its lack of range resolution. In this paper, we propose a three-dimensional (3D) directional modulation (DM) using randomized radiation with FDSA for enhanced PLS, employing a planar array. In addition, nonuniform frequency offsets (FOs) are considered as FO configurations (FOCs) for FDSA to concentrate on the mainlobe and suppress the undesired sidelobes in 3D space, where logarithmically increasing FOC (L-FOC), Hamming window-based FOC (H-FOC), and piecewise trigonometric FOC (P-FOC) are introduced. Characterizing the process of selecting the random subsets for randomized radiation, we provide the exact analysis of the secrecy rate of the proposed scheme. Moreover, FOs applied to FDSA and the number of random subsets are optimized with a genetic algorithm (GA)-based optimization strategy. We evaluate the proposed schemes in terms of secrecy rate and vulnerable volume, where the simulation results verify our analysis and show that nonuniform FOCs are a more favorable choice for FDSA compared to uniform FOC (U-FOC). © 1972-2012 IEEE.

In the era of precision agriculture, effective and efficient monitoring of rice paddy fields is vital for optimizing crop yield and ensuring environmental sustainability. This study presents a novel approach utilizing a grid-structured Wireless Sensor Network (WSN) to monitor key environmental parameters such as soil moisture, temperature, and methane gas concentration. The novelty of this research lies in the detailed implementation of a grid-based sensor system that provides comprehensive coverage, enhanced data precision, and integration with artificial intelligence (AI) for predictive analysis. This system not only enables realtime monitoring but also generates actionable insights through a color-coded alert system that signals abnormal conditions such as excessive heat or harmful gas levels. The study demonstrates significant improvements in resource efficiency, including water management and reduced chemical usage, resulting in higher crop yields. The results highlight the potential for grid-based WSN systems to drive sustainable agriculture, offering precise interventions based on real-time environmental data. © 2024 IEEE.

Urban centers are grappling with increasing traffic congestion, which hampers mobility and reduces the effectiveness of emergency responses. Current traffic management systems struggle to dynamically prioritize emergency vehicles during peak congestion, highlighting the need for an advanced solution that improves both everyday traffic flow and emergency response efficiency. Traditional traffic light systems typically follow either fixed schedules ("Fixed"approach) or make real-time adjustments without achieving long-term efficiency ("Greedy"approach), often failing to effectively balance regular traffic dynamics with emergency needs. We propose the "Avg Log "method, an adaptive Q-learning strategy that enhances conventional traffic management systems by incorporating an emergency-aware module. This module uses real-time data to prioritize emergency vehicles and adjust traffic signals accordingly. Additionally, our approach employs a multi-objective optimization algorithm to strengthen communication infrastructure, optimizing latency, throughput, and reliability. Through simulations in a multi-intersection urban setting, we compared the performance of our method against the standard "Greedy"and "Fixed"approaches. Key metrics assessed included average waiting times, system throughput, and the efficiency of emergency vehicle passage. The "Avg Log"method outperformed traditional methods, showing superior long-term adaptability and learning. It demonstrated lower average waiting times and effectively managed emergency situations, significantly reducing delays for emergency vehicles compared to both control methods. This method provides an efficient balance between overall traffic flow and emergency prioritization, suggesting a scalable solution for complex urban environments. © 2025 IEEE.

Improving technology in the field of education will greatly help teachers and students in various ways, one of which is attendance. An attendance system generally leaks security and verification which may lead to fraud activity. In this paper, the authors design an attendance system that utilizes multiple verifications using card tapping and face recognition which is also accompanied by an anti-video spoofing system. The designed system is implemented as a web application with various algorithms such as Convolutional Neural Network (CNN), and Deep Metric Learning (DML) along with the application of the PN532 sensor and the use of ESP8266 for tapping the card. Our experiments show that the proposed system performs well, achieving up to 87.50% system accuracy. © 2022 IEEE.
