The problem of speech denoising using wavelet packet decomposition algorithm is considered. For denoising, certain wavelet packet coefficients (frequency) are set to zero and the others are thresholded. We make a comparation of wavelet-packet coefficients algorithm and amended wavelet-packet frequency algorithm in the application of speech denoising. The amended wavelet-packet frequency algorithm is proposed and implemented that can further improve the performance of the denoising system. © 2011 IEEE.

In this paper, we prompt a new multi-dimensional logistics method based on the Internet of Things (IOT). Internet of Things is a good enabling technology for logistics and supply chains which implements seamless, real-time tracking and monitoring goods at the level of items. In this paper, we propose a solution, which adopts RFID/GPS/3G/GIS technologies to implement real-time surveillance of logistics in transit. Based on the proposed solution, we chose the tabacco logistics as an example and developed an actual monitoring system for Logistics & Distribution Center of China, which successfully implements real-time vehicle tracking and cigarette packages monitoring. The outcome indicates that this solution minimizes missing goods and effectively reduces wrong delivery. © Bu et al.

In power quality monitoring system, there are unavoidably existing various kinds of noises in collected data, presence of noise may result in increased false classification rate, denoising is an extremely important work for detection and classification of power quality disturbances. In order to improve the denoising result of power quality signal, an denoising method for power quality signal using Savitzky-Golay is proposed. Numerical results show that the proposed method can eliminate the influence of noise components and implement transient power quality disturbance detection and localization, thus providing good foundations for transient power quality disturbance monitoring under noise environment. © (2013) Trans Tech Publications, Switzerland.

Uncertain statistics is a methodology for collecting and interpreting the expert's experimental data by uncertainty theory. In order to estimate uncertainty distributions, an optimization model based on analytic hierarchy process (AHP) and interpolation method is proposed in this paper. In addition, the principle of least squares method is presented to estimate uncertainty distributions with known functional form. Finally, the effectiveness of this method is illustrated by an example. © 2014 Yongchao Hou.

P+a-SiC/ I nc-Si/N+a-Si structure solar cells is simulated by AMPS-1D program package to characterize the new thin film solar cell. In order to analyze the characteristics of the device, the thickness of layer are considered. The results show that the thickness of layer and the value of layer have a great effect on the conversion efficiency. Our results suggest a high performance P a-SiC/ I nc-Si/N a-Si structure solar cells with high efficiency of 14.411% and fill factor of 0.738. The simulation result is potentially valuable in exploring gradual bandgap P+a-SiC/I nc-Si/N+a-Si structure solar cells with high performance. © (2013) Trans Tech Publications, Switzerland.
