In this paper we have applied radial basis function neural networks for equalization of wireless channel in the presence of additive noise. We have been tested the adaptive filter algorithms of simple Kalman filter, extended Kalman filter, rbfn Kalman filter, rbfn extended Kalman filter, fuzzy Kalman filter and fuzzy extended Kalman filter which might be considered applicable for wireless chann...

A microfluidic passive pumping method relying on surface tension properties is investigated and a physical model is developed. When a small inlet drop is placed on the entrance of a microfluidic channel it creates more pressure than a large output drop at the channel exit, causing fluid flow. The behavior of the input drop occurs in two characteristic phases. An analytical solution is proposed ...

Mobility nature of the mobile nodes has the most obvious problem, call drop. A handoff methodology should ensure drop rate reduction for the proper functioning of the network. Call drop may occur mainly because of the loss of signal strength when the mobile node moves away from the coverage of the base station and bandwidth starvation because of the congestion. Congestion can be handled by redu...

This study explores hydrodynamic instability and pressure drop in a water-cooled two-phase micro-channel heat sink containing 21 parallel 231 713 lm micro-channels. Two types of two-phase hydrodynamic instability were identified: severe pressure drop oscillation and mild parallel channel instability. It is shown the severe pressure drop oscillation, which can trigger pre-mature critical heat fl...

A channel filter has been designed for Digital Down converter (DDC),that meets the standard of WiMAX in wireless communication. WiMAX is a technology emerging in the wireless communication system, in order to enhance the broadband wireless internet access. Digital Up Converter (DUC) and Digital Down Converter (DDC) are integral part of WiMAX system, that results in efficient low cost WiMAX syst...
