The decomposition process for the extraction of harmonics components from compressed power quality data was required under the frame of Shannon sample theory, but it increased the complexity of data procedure. A compressed sampling matching pursuit (CoSaMP) method was presented to detect harmonics from compressive sensing (CS)-based compressed power data sequence avoiding decompression pretreatment...
A power quality data compression method combining compressive sampling with adaptive matching pursuit reconstruction based on compressed sampling theorem is presented to solve the massive power quality data collection, compression and storage problems. First, the original power quality data was sampled and compressed simultaneously by random matrix projection method based on compressed sampling theorem...
In the past decade, the Internet has witnessed an incredible growth in its pervasive use. People are enjoying unprecedented convenience brought by the Internet boom. However, an increasing amount of unwanted traffic, such as spam and malware, severely burdens both users and Internet service providers (ISPs), which arouses wide public concern. A Global Trust Management (GTM) system was proposed and...
Aluminum nitride (AlN) films were deposited on FTO substrates by RF sputting using self-prepared AlN target. The structure and optical properties of AlN films were studied by XRD, SEM and UV/VIS spectrum.
