There is no flexible and dynamic service comp.sition method for comp.sing the comp.ex service from the simple basic services in pervasive comp.ting. A dynamic service comp.sition method based on semantic interface matching is introduced. It gives system framework for the elementary service description schema based on semantic, the comp.sition service description schema, the arithmetic for creating the inst.nces of comp.sition service, and the control method for service. This method also verifies the framework by inst.nce implementation. It is very useful for effectively using the system resource and reducing the comp.exity designing and implementing the services by comp.sing the comp.ex services from the elementary service.

The acyclic property of database data structure is an important property of the database theory and application. How to make an acyclic decomp.sition of the database schema is a relatively comp.ex problem, and more comp.ex is the α-acyclic decomp.sition problem when there exist inside conflicts in FD set F. Discussed in this paper is that when there exist generalized left-hand side conflicts or generalized right-hand side conflicts in FD set F which has inside conflicts, the relationship between the generalized left-hand side or generalized right-hand side conflicts and the symmetrical left-hand side attribute set, and the existing condition and property of the symmetrical left-hand side attribute set. The corresponding concepts, theorems and proof are also given. On this basis, a decision algorithm of the existence of generalized left-hand side or generalized right-hand side conflicts is presented. The correctness verification and algorithm analysis of the above mentioned algorithm are presented too.

In consideration of specialization, discrete demands and comp.exity of the applications in railway geographic information system, a spatial analysis service framework based on MVC pattern is provided. This model is comp.sed of three tiers: data tier, application tier and presentation tier. The spatial analysis comp.nents exist as independent parts to provide spatial data analysis service in a multitude of forms. The model frame takes the technology of distributed comp.nents as the means for its realization. Multi-form applications on the railway are divided into user views, spatial models and controllers. On the basis of that frame, the application in car tracing is realized based on the comp.ehensive safety monitoring information on Shanghai-Nanjing line.

Face Detection is of great practical significance. In the process of face detection, people tend to concentrate on the core area with outstanding characteristics such as the eyes, the nose and the mouth, but ignore the fact that the color of the cheek and the forehead is fairly smooth in comp.rison. This paper brings forward the concept of the Smoothing of Skin Color. By this concept and together with HSV color model, we can successfully segment the face image. The experimentation shows the method that this paper adopted could conveniently, rapidly and effectively segment the faces from any rotation angle, in any light conditions and under any color background.

This paper has studied service architecture of multi-source remote sensing (RS) data's distributed service system based on SVM. First, this paper has set up a solid index mechanism of Pyramid, Block, Layer, Epoch according to the properties of RS data and analyzed the organization and storage of multi-source RS data on background. Secondly, this paper has designed parallel processes aiming at the background server's service functions. Moreover, these processes have been tested and analyzed for the improvement of parallel comp.ter cluster performance as background server based on SVM. Also, this performance improvement of the parallel PCs background server has been demonstrated.

Time independent invocation is very important for large-scale distributed applications, mobile applications and enterprise application integration. Though the callback asynchronous mechanism and polling asynchronous mechanism are supported by the current distributed object-oriented middleware, time independent invocation mechanism is not supported by now. To solve this problem, this paper presents a new asynchronous messaging model RAAM (Router Agent based Asynchronous Model). RAAM is based on the research results of the asynchronous model in Starbus platform, which is developed by the School of comp.ter sci.nce, National University of Defense Technology. RAAM model supports asynchronous messaging, time independent invocation and quality of service. We verify RAAM model on top of asynchronous subsystem of distributed object-oriented middleware platform Starbus. Finally, the comp.rison with other systems is given at the end of this paper.

A new 20 color none uniform quantization algorithm based on HSV space was proposed with the purpose of reducing the dimension of feature space and syncretizing the transcendental knowledge into the classification machine constructed by SVM. comp.ring with the traditional color quantization algorithms, the comp.exity of time and space decrease and the retrieval accuracy is improved. The transcendental information can be syncretized into the nucleus function of SVM to improve the effect of classification. Experiments show that the new algorithm proposed can be successfully used in retrieving the image from good-sized image database and extracting semantic information from image automatically.

A new multi-step curve search method for unconstrained minimization problems is proposed. The convergence of the algorithm is proved under some mild conditions. The linear convergence rate is also investigated when the objective function is uniformly convex. This method uses previous multi-step iterative information and curve search rule to generate new iterative points. Using more previous iterative information and curve search rule can make the new method converge more stably than traditional descent methods and be suitable to solve large scale problems.

In this paper, we present a novel integrated bio cell processor to handle individual embryo cells. Its functions are comp.sed of transporting, isolation, orientation, and immobilization of cells. These functions are essential for biomanipulation of single cells, and have been typically carried out by a proficient operator. The purpose of this study is the automation of these functions for effective cell manipulation using a MEMS based bio cell processor. This device is realized with relatively simple design and fabrication process. To transport cells, microfluidic channel is employed. The isolation of a cell is performed by actuation of polypyrrole(PPy) valves. The orientation control of cells is accomp.ished by dielectrophoresis(DEP). By the suction from the micro-hole, the target embryo cell is immobilized. Experimental results show that this device can substitute the essential but very tiresome and repeatable embryo cell manipulation and contribute significantly to the improvement of speed and success rate of operation by facilitating the cell manipulation. The cell viability test for the device is studied through the distribution of mitochondria in mouse(B6CBA)embryo cells and cultivation of cells for 86h after cell was manipulated by DEP.

Using the given minimum support and minimum confidence, a large set of association rules with linguistic terms can be discovered and therefore it is difficult for the users to obtain the most interesting ones. An algorithm for mining typical association rules with linguistic terms is presented. In this algorithm, the mined association rules with linguistic terms are grouped by the same consequent, and the association rules with linguistic terms in each sub-group are clustered by the dissimilarity between the rules. The association rules with respect to the medoids are selected as the typical association rules with linguistic terms. These typical association rules with linguistic terms are the most representative rules in the set of association rules with linguistic terms.
