Retrogression-reaging and hot forming of AA7075
The retrogression-reaging (RRA) and hot forming behavior of AA7075 were studied. AA7075 is a high-strength alloy used in applications where weight is of particular importance, such as in automobiles. Like many of the high-strength aluminum alloys, AA7075 requires elevated temperature forming to …

Stationary Exercise Bicycle Instrumentation and Verification of OpenSim Pelvic Residual Loads in Seated Cycling
… with the OpenSim residual reduction algorithm (RRA) tool excluding seat and handlebar loads. The RRA pelvic residual was then compared to an experimentally determined handlebar and seat equivalent (HBSE) calculated from respective load cell data. Graphical comparisons of the RRA and HBSE results …

Investigating self-assembly of linked oligomeric PPV-based materials
… study of regio-regular (RR) and regio-random (RRa) alkoxy-linked pentamer poly(2-methoxy-5-(2’-ethylhexyloxy)-p-phenylenevinylene) (MEH-PPV) illustrates the limited effect of regioregularity of the side chains on self-assembly. Through synthetic structure, it is possible to design highly …

Adaptive radio resource management schemes for the downlink of the OFDMA-based wireless communication systems
… is to design adaptive radio resource allocation (RRA) algorithms that distribute the scarce resources more fairly among network users while efficiently using the resources to maximize system throughput. Four scheduling algorithms have been formulated and analysed based on fairness, throughputs and …
