Abstract: Existing research on efficiency optimization for wireless power transfer (WPT) systems is limited by complicated models and low control accuracy. In this article, a data-driven efficiency ...

Abstract: Reconfigurable intelligent surface (RIS) technology has emerged as a promising energy efficient solution to enhance the transmission performance so as to enable sustainable future wireless ...

Abstract: Reliable and energy-efficient wireless transmission is very important for the future success of Internet of Thing (IoT). Due to the sporadic nature of IoT transmissions, the energy ...

Abstract: Bilevel optimization involves a hierarchical structure where one problem is nested within another, leading to complex interdependencies between levels. We propose a single-loop, tuning-free ...

Algebra is a core part of mathematics that develops critical thinking and problem‑solving skills. Among its many topics, inequalities stand out as both essential and challenging for students. Whether ...

Abstract: Given the ubiquity of power electronic converter (PEC) systems, they often represent the weakest link in terms of reliability within modern power and energy systems in different applications ...

Abstract: Due to the inherent complexity of modern polymer extrusion lines caused by nonlinear, dynamic behavior with numerous influential factors, disturbances lead to higher scrap rates and ...

Abstract: Efficient end-of-life products disassembly is crucial in the remanufacturing process. However, hazardous and repetitive disassembly tasks raise labor costs and decrease safety and efficiency ...

This week’s NBA Power Rankings will lean heavily into talk about the NBA trade deadline on Thursday (Feb. 5, 3 PM ET), but there’s more going on than just rumors. (39-11, last week No. 1) The team ...

Abstract: The rapid growth of artificial intelligence (AI) has led to increased reliance on power-intensive Graphics Processing Units (GPUs), which are essential for training and deploying large-scale ...

Abstract: High-frequency signals were widely studied in the last decade to identify grid and channel conditions in power lines. Power Line Modems (PLMs) operating on the grid’s physical layer are ...

Abstract: This paper presents a Bayesian optimization-based framework for incorporating small-signal stability constraints into the optimal power flow (OPF) problem. First, a mathematical optimization ...
