Subthreshold Signal Enhancement in a Space-Dependent Damped Van der Pol-Duffing Oscillator via Vibrational Resonance

Usama Bello Ibrahim*, Hamza Mustapha, Mannir Ahmad, Adamu Abubakar Sa’idu

This paper presents a numerical study of a subthreshold signal enhancement in a Van der Pol-Duffing oscillator, via the phenomenon of vibrational resonance. The oscillator describes a particle motion in a bistable periodic potential, influenced by space-dependent damping and excited by an external bichromatic excitation. Temporal and spectral analyses approaches were employed to analyze the system...

Development of Optimized Maximum PowerPoint Tracking Scheme for A Partially Shaded Photovoltaic System

M. Aderinola*, A.S. Abubakar, A. B. Kunya

Solar energy harnessed through photovoltaic (PV) technology plays a pivotal role in generating electrical energy. Maximizing the power output of solar modules requires optimal solar radiation. However challenges arise due to obstacles such as stationary objects, building, tree leaves and winds, which can result in the presence of multiple points of maximum power on the PV curve. This problem neces...
