After a research on railway project cases, we find that in some China companies, project cost control is such weak, even though the railway project has a huge number of investments with a short construction period. So to solve this problem, this paper constructs WBS standard templates and dictionaries of Four-Electrical (Communication, Electricity, Electrification, Signal) railway projects, based...
The problem of chaos rapid judging in traffic flow was studied using neural networks with particle swarm optimization (PSO). Based on analyzing the demand of intelligent transportation system and the problems of the existing methods of chaos identifying, the intelligent method of chaos rapid judging in traffic flow was proposed. The principle and the structure of the system are briefly introduced...
In order to do automatic evaluation for summarization much more accurately and efficiently, this paper analyzed the present evaluation methods of automatic summarization concretely, and pointed out the shortcoming of these evaluation methods. Based on the method of vector space model, it presents an evaluation method of automatic summarization calculating the similarity of text based on HowNet. It...
Traditional methods of optical flow estimation are poor in uneven brightness variation environment .This thesis solves this problem by generalized dynamic image model (GDIM). And according to the combination of the rich color information in color images and generalized dynamic image model, a model of color image sequence optical flow computation is presented in this paper. And the model presented...
