Wireless relay has been proposed as the solution to extend the coverage of a single base station. In this paper, capacity degradation due to multi-hop relay has been analyzed in a WiMAX relay system. It has been shown that ...

Cathodoluminescence has recently been used successfully in detecting and determining the spatial location of the amorphous phase in plasma sprayed calcium phosphate coatings. The aim of this study is to determine whether ...

Centrifugal slurry plumps experience accelerated erosion. Research to understand and to control has been inconclusive. This investigation is being conducted to qualitatively examine the patterns of accelerated erosion in ...

Centrifugal Compressors, which offer good flow stability, compact size and high stage pressure ratio, have been widely used in helicopter engines and sometime served as high pressure stage in small turbojet engines. In ...

This study contains the results of experimental tests performed at the University of Queensland in order to evaluate the ability ofCFRP wraps in strengthening an exterior beam-column connection subjected to cyclic loads. ...

This paper presents the results of cardiovascular changes that occur during a novel rehabilitation strategy called activity based therapy (ABT). Blood volume pulse (BVP) signals were measured during functional electrical ...

Ultra-WideBand (UWB) has been recently presented as a promising radio technology due to the large bandwidth available. This feature enables point to point high data rates at short range as well as high temporal resolution ...

This paper proposes an optimal training design for an amplify-and-forward (AF) relay system in which the source, relay and destination are all equipped with multiple antennas. Examined is the scenario when spatial correlation ...
