Review on Electrical Motor and Pump Assemblies in Ventricular Assist Devices & Total Artificial Hearts

Abstract Pump and motor assembly plays a vital role in the design of the Ventricular Assist Devices (VAD) & Total Artificial Hearts (TAH). Heart’s pulsatile blood flow was first mimicked by pulsatile flow devices. However, due to the compact sizing of the continuous flow devices, have shown significant decrease in the mortality rate. Pulsatile and […]

Performance Analysis of Channel Capacities in Different Diversity Techniques

Abstract In broadcast communications, a diversity scheme refers to a technique for enhancing the reliability of a message signal by utilizing at least two correspondence channels with various attributes. In this paper we consider all four possible scenarios: Multiple-input and multiple output (MIMO), multiple-input and single-output (MISO), single input and multi-output (SIMO), and single-input and […]

Adaptive Neuro-Fuzzy Based UPQC in A Distributed Power System for Enhancement of Power Quality

Abstract The power quality problems during distribution of power are mainly occurs due to transient distortions in the line voltage like harmonics, flicker, sags and swells. These power quality issues can cause damage of equipment, losses in power transfer or even can lead system towards instability. To alleviate these complications, ANFIS based UPQC is to […]

Robust Study and Evaluate the BER Performance of Multiuser Massive MIMO Systems

Abstract The need for higher data rates led researchers to propose another technique called a multiuser massive MIMO system that offers a larger bandwidth compared to the present wireless communication systems. In addition, significant improvement in communications quality of service (QOS), energy and spectral efficiencies and in the reduction of the cost is expected in […]

A Hybrid Pattern Recognition System for Detecting Buried Object in GPR Images

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 […]
