Video reconstruction quality largely depends on the ability of employed sparse domain to adequately represent the underlying video in Distributed Compressed Video Sensing (DCVS). In this paper, we propose a novel dynamic global-Principal Component Analysis (PCA) sparse representation algorithm for video based on the sparse-land model and nonlocal similarity. First, grouping by matching is realized...
A new hybrid active power filter, composed of passive power filters and active power filter, is proposed for harmonic suppression and high capacity reactive power compensation. A kind of configuration of the hybrid power filter has been presented and its basic principle is addressed, furthermore, the design of passive power filters and the analysis of harmonic current injected by active power filter...

This paper discusses the development of a wireless sensor network based target tracking platform. The platform involves ultrasound sensors for target detection and extended Kalman filter (EKF) for tracking a single target. The embedded application is implemented by TinyOS/nesC, and Lab view is used to develop the GUI. In order to optimize the energy consumption and to prolong the lifetime of the network,...
As China is developing smart grid with great strength, more and more digital substations will be built, therefore, it is time for thinking of the accuracy of metering devices. But the digital input electric energy meter is different on signal transmission with traditional meter, requiring a new calibration method. By sampling analog power standard output, we bring in a special power standard according...
