Industrial Wireless sensor networks (IWSNs) are emerging as a promising technique for industrial applications. With limited energy resources, prolonging the lifetime of IWSNs is a fundamental problem for industrial applications. At the same time, Software- Defined Networking (SDN) and Network Function Virtualization (NFV) are future network techniques which make the underlying networks and node functions...
For chip multiprocessor systems (CMPs), the interference on shared resources such as on-chip caches typically leads to unbalanced progress among threads. Because of the inherent synchronization primitives, such as barriers and locks, cores running fast threads have to waste precious cycles to wait for cores with slow progress, which leads to performance and energy inefficiency. For the purpose of...
Modern high performance Chip Multiprocessor (CMP) systems rely on large on-chip cache hierarchy. As technology scales down, the leakage power of present SRAM based cache gradually dominates the on-chip power consumption, which can severely jeopardize system performance. The emerging nonvolatile Spin Transfer Torque RAM (STT-RAM) is a promising candidate for large on-chip cache because of the ultra...
This paper briefly describes the principle of frequency conversion of inverter, highlighted application of inverter in the coal mine hoist, air compressor, fan. Frequency control devices with advanced control performance, higher energy efficiency, not only improve the control performance of the electrical equipment of coal, but also greatly save the energy. Conducive to the achievement of the coal...
