We investigated whether patients receiving RTx who live farther from their attending nephrologist are more likely to die than those who live closer. A random sample of 167 patients who undergone RTx between 1996 and 2004 was examined. We calculated the distance between each patient's residence and the practice location of their attending nephrologist. We(More)
In this work, artificial neural networks (ANNs) technique was used in the prediction of abrasive wear rate of Cu–Al 2 O 3 nanocomposite materials. The abrasive wear rates obtained from series of wear tests were used in the formation of the data sets of the ANN. The inputs to the network are load, sliding speed, and alumina volume fraction.

Over the last several years, the customer-driven wireless market has pushed the developers of RF hardware towards more functionality in less volume, operation at ever higher RF frequencies, and greater circuit and functional integration. Additionally, the pressure to reduce costs has forced designers to look at less expensive manufacturing, assembly, and(More)
