This paper focuses on the multifaceted exploration of energy transition strategies in Kosovo, with a particular emphasis on the potential for repurposing degraded lands for renewable energy generation. As a developing nation grappling with increasing electricity demand and environmental concerns, Kosovo seeks to reconcile economic growth with ecolo...

Marine ecosystems are complex and dynamic environments. Monitoring these ecosystems is essential for understanding and identifying potential threats and conservation needs. Different sensory devices such as wireless sensor networks (WSNs) are used to monitor these environments. WSN have been in industrial use for the last two decades. However, ener...

The growing demand for energy, driven by rapid economic development, necessitates higher electricity consumption. However, conventional energy systems relying on fossil fuels present environmental challenges, prompting a shift towards renewable energy sources. In Kosovo, coal-fired power plants dominate electricity production, highlighting the need...

This study analyzed the student dropout rate at the Faculty of Electrical and Computer Engineering (FECE) of the University of Pristina, Kosovo, from 2001 to 2015.

The use of SPWM and SV-PWM Voltage Source Inverters are the common type of Variable Frequency Drive (VFD) for 3-phase induction motors in the industry. Even though the SPWM technique has an easier implementation, the SV-PWM has easier digital realization and better utilization of the DC link. Every 3-Phase PWM-Inverter that uses these two modulatio...
