The main objective of this study is to investigate the electrical properties of Sn–3.0Ag–0.5Cu solder joint with the incorporation of carbon nanotube instead of solder bulk. Sn–3.0Ag–0.5Cu solder paste with the i...

Abstract Current research on the fabrication of rolled composite plates primarily focuses on processing and bonding mechanisms. Compared with hot-rolling technology, the electrically assisted rolling process has demonstr...

Hydrogel of single-walled carbon nanotubes and polyaniline has been used for thermopower engineering applications due to desirable thermal, electrical, and mechanical properties as well as tunable degradability. In this ...

Abstract Precise control of electrical properties in conductive micro-structures is essential for the performance and reliability of micro-electro-mechanical systems (MEMS). However, the nature of anisotropic physical va...

The main objectives of the study are to develop a generalized thermo-electromechanical model of a solid-state heat engine based on a Ni-Ti-Cu shape memory alloy for converting low-grade thermal energy (30-100 °C) into e...

Manual cocoa bean inspection is subjective and prone to error, significantly impacting chocolate production. This study presents an automated, high-throughput cocoa bean grading system leveraging YOLOv10, YOLOv11, and Vi...

Abstract As a new composite welding heat source introduced in recent years, the cross-coupling arc uses a non-consumable electrode arc (plasma arc) and a consumable electrode arc (inter-wire arc) in cross-coupling, in wh...

Abstract Fiber Bragg gratings (FBGs) offer new possibilities to monitor accurately the rotor temperature. Dozens of sensors can be mounted in series in a single fiber and used to measure the temperature in several points...

This paper presents the design and experimental validation of a two-dimensional (2-D) circularly cylindrical phased array antenna with integrated wide-angle beam-switching capability for multibeam radiation in the Ku-ban...

Currently, numerous vocational colleges have incorporated practical training courses focused on automated production lines. However, due to spatial constraints and insufficient availability of physical equipment, the imp...

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...

Introduction. Stator flow-oriented control is currently the most widely used system in industry or in previous research for improving the quality of mechanical power generated by permanent magnet synchronous motors (PMSM...

We present a magnetically actuated vocal fold–phantom phonation system capable of reproducing longitudinal tension modulation to mimic cricothyroid (CT) and thyroarytenoid (TA) muscle activation. We first formulat...

This systematic review of 79 CubeSat antenna studies reveals a progressive “workflow attrition cascade” (68% $\rightarrow 70$ % $\rightarrow 87$ % $\rightarrow 92$ %) wherein electromagnetic design sophisti...

Abstract Coaxial aircells are designed and fabricated to measure the electromagnetic properties of ferrite materials in the frequency range from 1 MHz to 3.6 GHz. These S-parameters are actually measured connecting the a...

Introduction. Self-excited induction generators (SEIGs) play a vital role in renewable energy systems, particularly in remote regions. However, their performance is highly sensitive to excitation capacitance, rotor speed...

In the present study, the transmission error (TE) behaviour of an identical involute spur gear pair dynamically coupled with an attached subsystem is investigated through numerical modelling. The surrounding mechanical s...

Abstract A first-principles study of the structural, electronic, magnetic, mechanical, and optical properties of the double perovskite Ca₂GaAsO₆ is presented using density functional theory with the Perdew-Burke-Ernz...
