In this paper, the 3-D Markov analytical model for cognitive radio networks of [1] are replaced by out proposed new 2-D Markov analytical model with considerable low complexity to evaluate the performance of Ad-Hoc Cognitive Radio Networks, and the theory mistakes of [1] are corrected. Compared with the existing 3-D Markov analytical model for cognitive radio networks, our approach has achieved the...
Aging simulation is one of the hot issues in the field of realistic rendering. This paper presents a method to simulate the aging phenomena of 3D models with the combination of curvature analysis and color transition. For a given 3D model, we analyze the curvature of each vertex, so as to determine its global geometrical features. And then on the assumption that different areas reflect diversely in...
Used clinically since Penfield and Jasper's pioneering work in the 1950's, electrocorticography (ECoG) has recently been investigated as a promising technology for brain-computer interfacing. Many researchers have attempted to analyze the properties of ECoG recordings, including prediction of optimal electrode spacing and the improved resolution expected with smaller electrodes. This work applies...
Simulation analysis data proliferate in the process of product collaborative simulation, therefore, capability to access and manage the simulation analysis data is critical for the collaborative simulation. In order to achieving the integrality, coherence and traceability of simulation data, this paper proposed a management model of multi-dimensional simulation data of complicated product, which describes...
As one of the candidates of the next generation non-volatile memory(NVM), phase change memory(PCM) has been paid more attention. However, there are still many open issues such as numerical simulation to study. Phase transition is a temperature based process, which can be simulated by temperature profile generated by the device simulator coupled with the phase transition model. In this work, a phase...
