This study investigates the long-term aging effects and structural degradation mechanisms of photovoltaic (PV) modules integrated into smart city furniture, with a particular focus on panels of 10 W, 25 W, and 40 W nomin...

Abstract In this work a broadband Magnetoelectric (ME) dipole antenna for the Global Navigation Satellite System (GNSS) applied to nanosatellites is proposed. The antenna consists of a reflective cavity with open walls c...

Electric Discharge Machining (EDM) is a non-traditional machining process that utilizes electric sparks between an electrode and a workpiece submerged in a dielectric fluid to ablate a material. It is commonly used in di...

Power Circuit Breaker (PMT) is an electrical device used to connect or disconnect the flow of electricity at medium to high voltage. The purpose of this research is to evaluate the operational feasibility condition of th...

This study compares seven quantum algorithms—Variational Quantum Eigensolver (VQE), Variational Quantum Deflation (VQD), Quantum Approximate Optimization Algorithm (QAOA), Quantum Amplitude Estimation (QAE), Quant...

Abstract Transition metal dichalcogenide (TMD) solar cells are promising candidates for high-specific-power photovoltaics due to their strong light-matter interactions, such as their high absorption coefficients. The per...

Introduction. Nowadays, the most widely used wind energy conversion system in wind farms is based on a doubly fed induction generator (DFIG); it has a large speed range and can function in multiple modes. Problem. Harmon...

This paper describes an easy and time-saving strategy for the fabrication of heterogeneous nanotubular arrays of TiO2-CdS (TCHNTAs) on transparent conductive glass (FTO) and their photoelectrochemical properties. The use...

The effectiveness of piezoelectric footwear depends on accurately identifying the areas of the shoe that experience the greatest pressure during walking or running. These high-pressure zones are ideal for placing piezoel...

This study presents a structured, integrated methodology that combines Lean Six Sigma and TRIZ to support the transition of a wave energy converter from a laboratory proof-of-concept to an industrializable system. It add...

The electrical resistivity method is the main non-destructive method for measuring compaction and moisture migration of the unsaturated soils. The van der Pauw method is a well established technique for measuring the res...

This paper proposes an innovative model-free deep reinforcement learning-based controller (RL-C) for a grid-connected 5-level packed-U-cell (PUC5) multilevel inverter (MLI). The controller is designed to deliver a high-q...

Abstract Hydrogen generation from renewable energy sources allows balancing the intermittent nature of solar and wind power. The chemical energy stored in hydrogen can be efficiently converted back to electricity using f...

Abstract Superconducting Fault Current Limiter (SFCL) modules with distinct arrangements have been investigated, seeking design and performance enhancements. In this context, this work aims to propose a design for resist...

Introduction. Three-phase pulse width modulation (PWM) rectifiers are widely used in modern power conversion systems due to their high efficiency, controllability, and ability to provide high-quality energy conversion. T...
