This paper introduces a non-isolated high step-up DC–DC converter with reduced voltage stress on semiconductors. The proposed structure is based on two boosting techniques: a switched capacitor (SC) cell and a quadratic cell (QC). The proposed converter uses the advantages of SC and QC simultaneously to increase the voltage gain. Consequently, the converter has a much higher voltage gain compared to similar structures. High voltage gain, low voltage stress across semiconductors, no limitation of duty cycle, continuity of its input current, and the existence of a common ground between input and output ports are the most substantial features of the proposed converter and make it suitable for renewable energy applications. Among the compared high-step-up DC–DC converters, the suggested topology provides higher voltage gains at lower duty cycles. The power density of the proposed converter is improved. So, the volume of the suggested converter is reduced. Moreover, to prove the superiority of the proposed converter, the operation principles, steady-state analysis, and comparison with other similar high step-up DC–DC converters are presented. Voltage gain and voltage stress across semiconductors are compared and analyzed. Finally, the experimental results are displayed to prove the effectiveness of the proposed converter. © 2025 John Wiley & Sons Ltd.

The deterioration of transmission lines has a profound effect on the reliability and safety of the power grid. Accurate estimation of their age is critical for effective maintenance and investment planning. This paper proposes a method that combines the percentage statistical health index (%SHI) with failure probability curve-fitting (FPCF) to estimate the ages of overhead transmission lines. %SHI assesses equipment condition through scoring and weighting, while FPCF correlates SHI with the probability of failure. Evaluation of 924 towers situated in various terrains across Thailand reveals discrepancies between estimated and actual ages, influenced by environmental factors. To enhance reliability, proactive maintenance strategies such as regular inspections and advanced monitoring are recommended.

Modern systems assume a high degree of automation of technological processes. This is accomplished by dividing into smaller specifications. One such problem is the need to build a regulator. Classical regulation systems are well studied and actively used, but their effectiveness is greatly reduced by increasing the possible states of the object. In such cases, set of fuzzy logic can come to the rescue. The article examines its features. © 2022 IEEE.

Mapping to $k$ -input lookup tables ( $k$ -LUTs) is a critical process in field-programmable gate array (FPGA) synthesis. However, the structure of the subject graph can introduce structural bias, which refers to the dependency of mapping results on the inherent graph structure, often leading to suboptimal results. To address this, we present ELMap, an area-driven LUT mapping framework. It incorporates structural choice during the collapsing phase. This enables dynamic decomposition, maximizing local-to-global optimization transfer. To ensure seamless integration between the optimization and mapping processes, ELMap leverages exact $k$ -LUT synthesis to generate area-optimal sub-LUT networks. Experiments on the EPFL benchmark suite demonstrate that ELMap significantly outperforms state-of-the-art methods. Specifically, in 6-LUT mapping, ELMap reduces the average LUT area by 8.5% and improves the area-depth-product (ADP) by 5.8%. In 4-LUT remapping, it reduces the average LUT area by 17.6% and improves the ADP by 2.4%.

Starting from the period of the Covid-19 pandemic, when the presence of students in the university laboratories was very limited, the research work on remote laboratories significantly increased. The most affected aspect of students’ study experience at that time were the laboratory experiments intended to be conducted on-premises, in the university laboratories. The UbiLAB framework was envisioned as a digital space for implementing and conducting laboratory work and experiments that are rarely completely transferred into the digital world. Here we have identified two most difficult challenges: achieving a nearly realistic substitute for learning experiences in the actual physical laboratories, and a nearly realistic substitute for the social element of collaborative learning and “making friends” in the process. The innovative cloud-based UbiLAB framework addresses both challenges, digitizing various and diverse actual laboratory experiments through a simple and widely available platform, while enhancing the reality of students’ experience in the process.

This paper discusses the advantages of orchestrating distribution energy resources (DERs) within the distribution network and integrating third generation (Gen3) blockchain technology among a diverse range of customers. The implementation of peer-to-peer (P2P) energy trading aims to optimize local energy utilization, reduce energy costs for participants, and provide insights into profit margins for aggregators and the distribution system operator (DSO). The study focuses on three types of DERs, namely electric vehicles (EVs), photovoltaic (PV) systems, and battery energy storage systems (BESSs), to facilitate transparent and secure P2P energy trading. The results underscore the importance of Gen3 blockchain technology in expediting and enhancing energy trading processes, thereby benefiting a wide range of participants.

Bilevel optimization with traffic equilibrium constraints plays an important role in transportation planning and management problems such as traffic control, transport network design, and congestion pricing. In this paper, we consider a double-loop gradient-based algorithm to solve such bilevel problems and provide a non-asymptotic convergence guarantee of O(K−1) + O(λD) where K, D are respectively the number of upper- and lower-level iterations, and 0 © 2023, CC BY.
