Abstract: To one company, it takes 8 major economic indicators as evaluation indexes. Firstly, it uses correlation method to determine the weight and uses the double-point method to sort the 8-years comprehensive economic enterprises. Then through the analysis of the correlation matrix, it identifies the main factors. Finally, the ranking and principal component analysis results are compared and analyzed.

Abstract: In this paper, a class of higher-order neutral delay difference equations is investigated. Some sufficient condition of the asymptotic behavior and existence of positive solutions for the equations are obtained. At last, we give their applications to some more general equations.

Abstract: This paper is to discuss the competition and cooperation of portal and search engine mainly by building stability model. We can use Lotka-Volterra mutualism model to describe and build cooperation model of portal and search engine, and we can use Lotka-Volterra predator – prey model with Logistic items to describe and build competition model of portal and search engine.

Abstract: This paper will focus on the control method of the brake test- bench, we have used physics, theoretical mechanics, numerical methods method and use Matlab software, Excel software to calculated data and drawing. Eventually we establish a mathematical model to control electric current. . The model will help us testing the merits of the brake, and assist us in the design process.

Abstract: Using technology, cooperation among peoples, lawyers are very special, it is rare. We believe that these two professionals working closely together in the field of ODR are essential. The co-operation we have in mind exists in drafting legal principles and technical requirements to develop and eventually implement an online negotiation environment. The online environment should different from other online negotiation environments in that the legal principles and technical requirements, on which the environment will be based, are developed in close cooperation and therefore fully adjusted to each other.
