in this work, homogeneous thermochemical co-precipitation method was used to fabricate w-25wt%cu nanocomposite. synthesized nanocomposite powder was calcined and reduced. a hydrogen atmosphere sintering at 1200oc for 105 consolidated the product up to a density close to 98% theoretical density. wear experiment were carried out using a pin-ondisc set up at three normal loads of 5, 10 and 15 n an...

In a system offering on-demand real-time streaming of media files, data striping across an array of disks can improve load balancing, allowing higher disk utilization and increased system throughput. However, it can also cause complete service disruption in the case of a disk failure. Reliability can be improved by adding data redundancy and reserving extra disk bandwidth during normal operatio...

The minimizing to reactive power of control winding of the dual stator-winding induction generator is key optimization of the novel generator system. It is determined by parameters of machine, load, rotating speed and speed range and exciting capacitors paralleled with the output terminal of power winding. In this paper, Based on analysis on working principle of conventional three-phase inducti...

Due to the failure-prone and vulnerable structure of WSN nodes, understanding typical activity patterns nodes helps identify faulty malicious node activities, differentiate normal behaviors from abnormal behaviors. In this study, for we observe effects network load on energy consumption, packet throughput, latency parameters. We run simulations networks with a variable number sinks. found that ...
