In this study, we explore the design, simulation, and deployment of a passive RC low-pass filter, specifically targeting its integration within Internet of Things (IoT) applications. We employed a symbolic computing environment to theoretically model the filter's frequency response, analytically deriving the transfer function and numerically valida...

In this study, we investigate the ultrafast dynamics of free electrons in skin-like tissue media, stimulated by laser pulses with durations between 50 fs and 100 fs. Our analysis is based on a rate-equation approach for the evolution of free electron density  under different laser pulse durations. The simulated electron densities are then used...

 The study investigates the laser-induced breakdown (LIB) in gases, essential for plasma creation and rapid increase of free electron populations, highlighting its significance in scientific and technological areas like energy deposition and radiative emissions. It explores electron dynamics during LIB, emphasizing the need for precise free el...

 This research focuses on the dynamics of electron behavior during the laserinduced breakdown (LIB) in skin tissues, pivotal for plasma generation in biomedical contexts. Through a numerical analysis centered on high-intensity Nd:YAG laser pulses within the 500–1000 nm wavelength range and a 10 ns pulse duration, we explore the balance ...

 The COVID-19 pandemic is a global health issue and has a major impact on education in different ways. Soon after the Republic of Serbia had confirmed the first case of the novel coronavirus pandemic in March 2020, all educational institutions were enforced to rapidly convert all their courses to emergency remote teaching and learning as a mit...
