This paper analyzes a spectrum access scheme based on region division for Device-to-Device (D2D) communication underlaying cellular networks with outage constraint for cellular communication. The D2D pairs will access the spectrum by sharing the cellular uplink (UL) frequency resources in the networks. By utilizing stochastic geometry, D2D accessing the frequency spectrum can be modeled as the probability...
In this paper, we present two new 3D panning methods. One method guarantees that time-average sound intensity and sound pressure of a virtual sound source at the receiving point are the same as time-averaged sound intensity and sound pressure of five loudspeakers at the receiving point. Another method maintains the direction of particle velocity and sound pressure. These methods can realize using...
Subband based blind source separation (BSS) has a great potential in solving the complicated convolutive mixing problems. However, its performance is largely affected by the permutation ambiguity problem during the synthesis stage. Researchers have suggested methods to correct the permutation by using the correlation information between adjacent frequencies/subbands. In this paper, we propose an improved...
Self-healing is the main cause to capacitance loss of metalized film capacitors, and it might finally lead to the failure of a capacitor. Teardown analysis shown that capacitance loss decreased gradually from the outer layers to inner layers in a capacitor, and it is said that the elastic films add compressive radial force to every wound wrap, the pressure brought up by the radial force has an significant...
