Based on correlation of the stock price fluctuation of the information services stock network in Shanghai A-share and Shenzhen A-share, this paper established a stock network according to the given weight of the company's relative value. Then it proposes a comprehensive directed weighted evolving network model that integrated fitness-based preferential attachment, node deletion, link establishment...
Proposed the method of slot cartridge hole blasting to improve the efficiency of gas drainage. First, by the mean of numerical calculation, we conducted the two-dimensional simulation study on the X-shape-slotted charge blasting in the coal. It was found that along the direction of the slot the perforative main crack formed, while in the other direction a dense network of secondary cracks formed,...
Lots of researches were focus on aerodynamic characters of the head, top and tail of vehicle in the past, but researches on bottom of vehicle were quite rare. This has been changed in these days. Optimization of aerodynamics via shape of vehicle was limited by modern automotive styling. So the focus has been moved to bottom of vehicle. In current work, the aerodynamic influence of ground clearance...
Two kinds of experimental dies containing class "A" surface feature of auto body outer panel are designed and manufactured in order to emerge the surface wrinkle of auto body panel. By doing stamping experiment in the dies, the wrinkling phenomenon is observed. At the same time, numerical simulation based on an independently developed commercial CAE software KMAS/UFT of sheet metal forming...
The channel outputs are sampled on nonuniform sampling sets, and an analysis of the decorrelation based on nonuniform sampling (NUS) is investigated. It is demonstrated that MUSIC algorithm with NUS of various array elements may be capable of selecting the signal of interesting including the coherent group. NUS in the time domain is equivalent to alter the relative distance between sensors and leads...
