Conditional access system (CAS) is a key technical component in digital TV broadcasting through which TV operators manage the appropriate rights of different subscribers in order to protect their commercial benefits. The normal digital TV receiver can only receive and decode the pay TV programs scrambled by one specific CAS. In this paper, the authors(More)
The propagation of oceanic mesoscale signals in the South China Sea (SCS) is mapped from satellite altimetric observations and an eddy-resolving global ocean model by using the maximum cross-correlation (MCC) method. Significant mesoscale signals propagate along two major bands of high variability. The northern band is located west of the Luzon Strait,(More)
Following the theory of linear piezoelectricity, we analyzed propagation of guided waves in layered piezoelectric structure. The pattern is a piezoelectric plate sandwiched between two piezoelectric half spaces. The waves propagate near intermediate plate. From this, we get precise dispersion relation which can be changed into to piezoelectric surface(More)
The objective of this study was to evaluate the electrophysiologic characteristics of Crista terminalis (CT) and their implication in the pathogenesis of atrial tachycardia in rabbits. For this purpose, 27 New Zealand rabbits were used. Using standard glass microelectrode technique, cellular action potentials (APs) of CT and pectinate muscle (PM) were(More)
Basing on the analysis of the studying situation of current routing protocol , this thesis presents a SD-Anycast protocol algorithm, and the routing principle and measure parameter of the protocol is given. By designing packet header, routing maintaining and node dealing modules, it implements this protocol in NS2. Lastly, some quantificational experiments(More)
