Abstract It is very difficult to evaluate the shape of the buried objects using Ground Penetrating Radar (GPR). In this study, 180 GPR B scan images were classified by using different classification algorithms. GPR-B scan images of objects with different shapes in various depths were obtained by using GprMax simulation program. Noise in these images […]

This paper focuses on improving harmonic performance of the multilevel inverter and quality of output voltage waveform compared to conventional two-level inverter. It uses two carrier wave and three reference waves which are generated fromSVPWM technique. […]
Abstract Non-minimum phase systems are difficult to control with conventional methods because of their inherent characteristics of undershoot. The complexity in control of such systems increases when time delay is added. These systems will exhibit undershoot in time-response and oscillations in the high frequency region in magnitude frequency response. This paper focuses on design of […]
