Importance Sampling is an unbiased sampling method used to sample random variables form different densities than originally defined. The importance sampling densities should be constructed to pick up ‘important’ random variables to improve the estimation of a interesting statistics. In this article,...

The domestic consumer price index is rising continuously, logistics is considered one of the factors is the impact of the high price index. The analysis of each industry logistics costs constitute the highest proportion of most transportation costs. However, the transport industry tariffs are generally...

For the shortcomings of integrity, fixity and closed of traditional courseware, for the purpose of improve the reuse, versatility and openness of courseware, this paper use Flash ActionScript 3.0 technology, develop a set of generic courseware integrableware system, and base on the system construct a...

According to the characteristics of Spatial Periodicity of fibers, wool and cashmere can be identified automatically by digital image processing technology. Fiber images were collected by Image acquisition devices and saved in computer. Then, fiber information like diameter, surface scale height and...
