Abstract: In this paper, we employ iterative analysis method of applied-information technology to obtain both the existence and the stability of first order functional differential equations with impulses for periodic boundary value problem. Some new results are obtained.

Abstract: A continue method based on relaxation is applied to solve the unit commitment problem (UCP). At first, the primal UCP is reformulated as a simple mixed integer quadratic programming (MIQP), and then the MIQP is solved by interior point method (IPM) and commercial software CPLEX. The first continues problem, UCP without integer constraints, can be solved by IPM to get the no integer solution. The second continues problem, an equivalent continues problem of UCP, can be solved starting from the solution obtained in first problem.

Abstract: This paper implements Tiger compiler on Hacs language. This compiler is likely to perform many or all of the following operations: lexical analysis, preprocessing, parsing, semantic analysis, and code optimization, target code generation. These are discussed in this paper in detail. As a new design language compiler, Hacs has the prominent advantages of high portability, maintainability and so on .It is easy to achieve.

Abstract: In order to avoid the flaw including rigid regulations of architecture, strong coupling among modules, removal of fault and advanced technology embedding hard in 3D graphics render engine, a customizable architecture for 3D graphics render engine platform was proposed. The architecture introduced some simulation models which were design standard, expansibility, assembly relation of simulation component resource, development of typical modules and component design. Application developer could customize simulation assembly component flexibly and compose own 3D graphics render engine generally.

Abstract: This paper develops a novel approach for the lightweight design of a car body frame. In this approach, the cross-sectional dimensions of a car body frame are treated as design variables. First, sampling points are created based on Latin Hypercube Sampling (LHS), and then Design of Experiment (DOE) is conducted. After that, an analysis is done to obtain those design variables affect the results most. Finally, Sequential Quadratic Programming (SQP) is utilized to solve the optimization problem while the amount of design variables is reduced according to the former analysis. The advantage of this method is that it reduces the burden of optimization algorithms and offers a practical way for the lightweight design of a car body frame.

Abstract: The characteristics of AJAX technology can read and write data without refreshing the page, so as to relieve the burden of server and speed up the response and shorten the waiting time for customers. The SSH framework is the organic integration of Struts, Spring and Hibernate three technologies. The e-commerce system has good hierarchical coding design thought of MVC system on the Struts2 framework. The paper presents application of AJAX and SSH framework in development of electronic commerce system.

Abstract: Ontology technology is the foundation of the semantic Web, and provides support for the definition of domain ontology to the clothing e-commerce direct knowledge base, so as to realize the electronic commerce platform based on domain knowledge. In this paper, the design of the clothing network marketing e-commerce platform is an integrated product sales, product management, marketing and sales information entrance, marketing, customer relationship management and other functional modules operating platform. The paper presents application of ontology technology in building knowledge base of e-commerce system in direct selling clothing network. Experimental results show that the proposed application technology has high efficiency.

Abstract: Nowadays, so many people are talking about the user experience of the website (UE or UX) and interface design called UI and so on, so let’s analysis the interactive pages by eye thermodynamic diagram and eye tracking based on Eye Tracking Technology.

Abstract: data stream management system is used to manage and query coming large, continuous, fast and flexible data stream. The system is based on the flow of data extraction, transformation, combination, which is the main content and task query execution. This paper mainly discusses the design and implementation of query execution module and query execution is composed of two parts which include query operations, query execution and scheduling.

Abstract: As an important branch of modern information retrieval technology, full-text search is not only an important tool for dealing with unstructured data, but also one of the mainstream technology of search engines .This paper starts from studying the working principles and process of search engine model in deep and discuss Lucene's architecture with previously knowledge. The main emphasis is placed on the problem of some basic algorithms of Chinese word segmentation and Relevance Ranking. Finally, we set up a system based on Lucene of full-text retrieval by applying these technologies.
