IMPLEMENTATION OF A PASSIVE RC LOW-PASS FILTER FOR EMBEDDED IOT SYSTEMS WITH OPEN-SOURCE SIMULATION SUPPORT
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...

SIMULATION OF ULTRAFAST FREE ELECTRON DYNAMICS AND TIME-DEPENDENT REFLECTIVITY IN SKIN-LIKE TISSUE MEDIA UNDER SHORTPULSE LASER EXCITATION
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...
