Abstract

The UCLA Loneliness Scale Version 3 (UCLA LS-V3) is the most widely utilized measure globally, with various iterations tailored to different cultural contexts. While initially conceived as unidimensional, the scale has been subject to both unidimensional and multidimensional interpretations. However, research on loneliness among Indian university students remains limited. This study investigates the psychometric properties of the UCLA LS-V3 in this population, revealing five distinct dimensions through exploratory factor analysis (EFA) and confirming construct validity through confirmatory factor analysis (CFA). The findings affirm the scale's suitability for assessing loneliness among Indian university students, contributing to the growing body of literature.

Abstract

Wireless power transfer (WPT) is emerging as a transformative solution to overcome the limitations of conventional plug-in charging for electric vehicles (EVs). This study aims to design and implement an efficient and reliable wireless charging system using inductive coupling with low requirements on the primary circuit. The proposed system integrates an Arduino-controlled high-frequency converter along with sensors and relays to optimize power flow, ensure safety, and reduce energy wastage. The methodology involves experimental rearrangement of transformers and frequency elements to achieve maximum efficiency while maintaining compact circuit design. Results demonstrate that the system can achieve efficient energy transfer suitable for short charging intervals, particularly beneficial for shuttle buses at stations and rental taxis at parking hubs. The findings highlight that wireless charging not only reduces total charging time but also supports cost-effective battery sizing, enabling improved vehicle turnaround and operational efficiency. In conclusion, this work contributes a weather-resistant, safe, and economically viable charging approach that sets new standards for EV infrastructure. Its implications lie in redefining charging stations along predetermined routes and stops, ultimately advancing sustainable and user-friendly electric transportation.
