CFD Analysis and Optimization of Fin-Enhanced Cooling Systems for Enhanced PV Performance
Abstract: This study examines how the performance of photovoltaic (PV) panels can be improved by means of passive cooling techniques through fin configurations. Computational Fluid Dynamics (CFD) simulation, validated with experimental data, was used to analyse the thermal behaviour of PV modules integrated with different fin shapes, namely rectangular, trapezoidal, and triangular geometries. It was found that trapezoidal fins yield better thermal performance, lowering the panel temperature by more than that …

New trends in Radio Frequency design and making things smaller
Abstract: Recent improvements in wireless communication, the Internet of Things (IoT), and 5G/6G networks have made people want small, powerful radio frequency (RF) equipment. With an emphasis on how developments in materials engineering, circuit architecture, and packaging technologies are redefining RF system integration, this article offers a thorough evaluation of current developments in RF downsizing. System-on-Chip (SoC), System-in-Package (SiP), and Antenna-in-Package (AiP) ideas, which allow tightly integrated RF front-ends with enhanced …

Estimation of Dulling Rate and Bit Tooth Wear Using Drilling Parameters and Rock Abrasiveness
Abstract: Optimisation of the drilling operations is becoming increasingly important as it can significantly reduce the oil well development cost. One of the major objectives in oil well drilling is to increase the penetration rate by selecting the optimum drilling bit based on offset wells data, and adjust the drilling factors to keep the bit in good condition during the operation. At the same time it is important to predict the …
