The integration of solar energy into modern power grids supports sustainability and energy efficiency but also introduces power quality (PQ) challenges such as harmonic distortion, voltage sag, swell, and fluctuations. I...

Due to the lack of access to grid electricity, milk preservation is a significant challenge in pastoral and rural areas of most African countries, despite the large volume of milk produced. Integrating milk pasteurizatio...

In off grid photovoltaic systems, the DC voltage from PV or batteries must be converted into a sinusoidal AC voltage that matches the AC voltage at home. The problem is that inverters available on the market are expensiv...

In a reciprocal medium, transmission of electromagnetic (EM) waves is symmetric along opposite directions which restrict design and implementation of various systems in optics and photonics. Asymmetric transmission (AT) ...

This study evaluates the cost implications of green building practices in low-rise residential housing by analyzing three sample houses in Kayseri, Türkiye. It compares traditional construction systems with green altern...

This study examines the role of artificial intelligence in improving the efficiency of photovoltaic (PV) systems through maximum power point tracking (MPPT) under dynamic operating conditions. A simulation-based model wa...
