To enhance the management of vegetable products quality and safety of Hebei Province, through practical research of vegetable enterprises, based on Web the authors design a quality and safety traceability system of vegetable products to enhance the monitoring of each participant in the production process. Combining the information and technology of the(More)
One of the difficulties with standard route maps is accessing to multi-scale routing information. The user needs to display maps in both a large scale to see details and a small scale to see an overview, but this requires tedious interaction such as zooming in and out. We propose to use a hierarchical structure for a route map, called a "Route Tree", to(More)
Text captions are important means to provide sound information in videos when the sound is not accessible. However, conventional text captions are far less expressive for non-verbal sounds since they are designed to visualize speech sound. To address this problem, we propose a method for automatically transforming non-verbal video sounds to animated sound(More)
A multiple spherical arrays structure is proposed to provide an alternative design to the traditional single spherical array for the spherical harmonic decomposition, to obtain better localization performance. The new structure consists of several identical spheres in a given area, and the microphones are placed uniformly on each sphere. The spherical(More)
Carbon nanotube (CNT) field-effect transistors (CNFETs), as one of the promising candidate emerging technologies, have distinctive device-level characteristics compared to conventional CMOS technology. Logical effort approach, which is an efficient approach for fast delay estimation in CMOS technology, however, is not universally applicable for CNFET-based(More)
This study experimentally investigates and numerically simulates the influence of the cathode electrode open ratio (ratio of oxygen-opening area to the total electrode surface area) on the performance of Li-O2 batteries at various discharge current densities. At the current density of 0.1 mA/cm2, the maximum discharge capacity is achieved at 25% open ratio(More)
A novel algorithm based on spherical harmonic analysis using multiple spherical arrays is proposed to localize wideband acoustic sources. In the novel spherical harmonic algorithm, the received microphone signals are firstly used to do the spherical Fourier transform. Then, the MUSIC algorithm is applied to the spherical components to obtain the(More)
