Abstract

Many employees in the company have not optimally mastered Excel formulas and functions, which hinders work efficiency and data-driven decision-making. This training is designed with an interactive approach, including both theoretical sessions and hands-on practice. Participants are provided with material on basic formulas, logical functions, and data analysis using Excel. Evaluations are conducted through quizzes and practical assignments to measure participants' understanding. After attending the training, 85% of participants showed an improvement in their ability to use Excel formulas and functions, based on the evaluation results before and after the training. Participants also reported increased confidence in completing tasks that require data analysis. This training successfully enhanced employees' skills in using Excel, positively impacting productivity and work quality. Recommendations for further training and regular monitoring are necessary to ensure these skills continue to develop.

Abstract

The extensive adoption and rapid expansion of mobile gadgets have positioned wireless power transfer (WPT) as a critical domain of scientific inquiry. A compelling feature of WPT lies in its ability to offer a versatile and economical charging solution, eliminating the necessity for a direct physical link to power outlets—a particularly beneficial trait when manual connection is impractical for the user. Historically, battery replenishment for such hardware has relied on wired systems, necessitating a tethered attachment to electricity via physical cabling. In contrast, WPT facilitates the transmission of energy through the air over brief spans, utilizing either magnetic fields generated by inductive coil coupling or electric fields arising from capacitive electrode interaction, which are subsequently captured by an antenna for functional use. This paper provides a comprehensive analysis of current WPT methodologies, their functional mechanisms, practical implementations, and prospective research trajectories within this nascent field. Despite existing limitations, WPT represents a transformative advancement poised to fundamentally reshape the operational framework of mobile networks, the Internet of Things (IoT), and associated future technological ecosystems.
