Silicon carbide nanowires have been synthesized at 1400 °C by carbothermic reduction of silica with bamboo carbon under normal atmosphere pressure without metallic catalyst. X-ray diffraction, scanning electron microscopy, energy-dispersive spectroscopy, transmission electron microscopy and Fourier transformed infrared spectroscopy were used to characterize(More)
The traditional way to composite texts and images over a video clip for presentation encounters such problems as time consuming, instructor skill scarcity, video retrieval difficulty, and video quality loss, especially, in internet high-compressed video materials. To solve these problems we develop a real-time remix platform for video-based presentation(More)
Feature extraction of event-related potentials (ERP) plays an important part in both basic and clinical researches for cerebral neurophysiology. ICA is a method for separating blind signals based on signal statistic characteristics. In this paper, the fundamental principle, the discrimination condition and the practical algorithm of Independent Component(More)
