Software Defined Networking (SDN) is a new networking paradigm which provides better decoupling between control plane and data plane. The separation not only allows OpenFlow (OF) switches in the data plane simply to forward data, but also enables the centralized programmable controller to control the behavior of entire network. SDN makes it possible to manage the network more flexible and simple....
In this paper, we report three applications of Graphics Processing Unit (GPU) based algorithms for high performance computation of mathematical models with the Fron Tier++ code. In the first set of simulations, the system of one-dimensional gas dynamics equations is solved by the Weighed Essentially Non-Oscillatory (WENO) scheme, we achieved 7-20 times speedup for different mesh sizes on one GPU device...
In speech enhancement based on wavelet package, a new concept of time-frequency thresholding and the corresponding algorithm are presented. Based on the masking properties of human auditory system to wavelet denoising, the threshold is modulated to vary with the time-frequency characteristic of the speech's pre-estimate, but not merely the time-variant information as has been adopted in former researches...
