Voice activity detection based on statistical models and machine learning approaches
The voice activity detectors (VADs) based on statistical models have shown impressive performances especially when fairly precise statistical models are employed. Moreover, the accuracy of the VAD utilizing statistical models can be significantly improved when machine-learning techniques are adopted to provide prior knowledge for speech characteristics. In the first part of this paper, we introduce […]
An improved low power wireless sensor network based on ZigBee for agricultural applications
This paper presents a low power ZigBee sensor network characterized by bidirectional communication and control of inter-node data pack reception designed for use in agricultural fields. The network consists of end devices with sensors, routers that propagate the network over larger distances, and a coordinator that communicates with the computer, which in turns illustrates the […]
Electrodeposition of Compositionally Modulated Nanowires for Racetrack Memory Applications
Racetrack memory, a memory device based on the current driven domain wall motion in a magnetic nanowire, has been recently proposed by Stuart Parkin and his group. In this proposed device, the information was stored as magnetic domain walls or domains in a wire. Nanosecond-long current pulses are applied to one end of the wire […]
