摘要：
The users' need for a mass of synchronization requests cause the appearance of more and more choke point at the end of the server. At present, the usual solution is to apply load balanced technology. This paper analyzes and explores the load balanced technology of VOD cluster server, and puts forward a self-adjusted genetic algorithm. The experimental results are perfect.

摘要：
In this paper, a genetic algorithm is proposed to design WNNs for nonlinear system identification. The model structure of a high dimensional system is decomposed into some submodels of low dimensions. By introducing a connection switch to each link between a wavelet and an input node, the decomposition is done automatically during the evolutionary process. GA is used to train the wavelet parameters and the connection switches. In this way, both the structure and wavelet parameters of WNNs can be optimized simultaneously. The proposed WNNs can handle nonlinear identification problems in high dimensions.

摘要：
Recent studies show much energy can be saved and the capacity of wireless sensor networks (WSNs) can be significantly increased when route nodes can have variable transmission ranges. However, this will result some problems difficult to be dealt with. It is well known that in WSNs, energy can be saved by setting the redundancy nodes in sleeping mode along the multi-hop routes. In this paper, we consider the energy efficient route schemes in a linear network with the sensors uniformly distributed and the candidate route nodes randomly deployed. To find an optimal energy efficient route, a dynamic programming algorithm (DPA) is presented to select the optimal route nodes and their transmission ranges. Simulation results show the efficiency of the algorithm.

摘要：
To meet the personalized needs of customers in E-commerce, a personalized recommendation service system based on E-supermarket (PRSSES) was proposed in the paper.. The structure of system and key technologies of realizing user interest module, personalized recommendation algorithm module am introduced in the paper. After the test use of the recommendation system by some community users, we found that the system could transform recessive demand to obvious demand. Thus, we thought it might be a practical solution to make more visitors become customers, to improve the loyalty degree of customer, and to strengthen cross sale ability of websites.

摘要：
It is unsuitable to use traditional identity-based authentication on the Web where entities are not foreknown to each other. Trust relationship must be established between strangers before authentication. To achieve trust authentication, the resource-constrained trust negotiation is addressed, and traditional authentication key exchange protocol is extended. Owing to avoiding the heavy computational demands the public key cryptography operations bring about, the authentication protocol is well-suited for security authentication on the Web.

摘要：
SNMP is nowadays the key enabling technology, which is adopted widely in the management of datacom products, such as switches, routers etc. Web-based management, which is one of the trends in network management field in recent years, has been seen rapid development. The author design a network management embedded agent frame integrating both of embedded web and SNMP technology. It combines preponderance of traditional mode and convenience of web.
摘要：
Objective: To discuss the effects of two-way traffic on TCP/AQM (active queue management) performance and solution. Methods We analyze how the two-way traffic affects the TCP/AQM performance. Results: We propose a policy that configures the acknowledgments (ACKs)-priority scheduling (AP) combined with active queue management (AQM) scheme in both forwards and reverse direction of route queue. Conclusion: By using this policy, the ACKs compression and the queue oscillation can be eliminated. Simulations indicate that the algorithm remarkably increases the performance of TCP/AQM under two-way traffic both symmetric and asymmetric links.
摘要：
The problem of tracking the distance between two convex polyhedra is finding applications in many areas of robotics, including intersection detection, collision detection, and path planning. An algorithm for computing the minimum distance between two convex polyhedra is presented. The algorithm applied to polyhedral objects that can be represented as convex hulls of its vertex value in three-dimensional space. Nonlinear programming techniques are then employed to compute the minimum distance between two convex polyhedra, and according to the minimum distance between two convex polyhedra, and according to the minimum distance, it can conclude whether or not the objects has collided at some time. The simulation results demonstrate the performance of this new method.
摘要：
Data fields in a form contain invaluable information so that field data extraction is important in form processing. Most conventional data extraction methods depend on the line frames. However there are many types of forms such as table-form and non table-from that are without line frames and popularly used in our daily lives as well. A new field locating method using priori knowledge is proposed. It is based on two-level regulated hit or miss transform features of form background. The feasibility of the method is proved theoretically. Experiments and application show that it is several dozen times faster than ordinary regulated hit or miss transform and the correct rate is satisfied with real applications.

摘要：
In this paper, we propose a routing protocol based on Multi-path Data Aggregation (MDA) for sensor network. First, we introduce the techniques, such as data aggregation and so on, then describe the implementation process of this protocol, and finally estimate its performance by our emulator. The simulation results show that because of this protocol, the nodes energy is reduced and the lifetime of network is extended.

摘要：
In order to improve the throughput, response speed and scalability of VOID server efficiently, many VOD server have thrown away single servers and turn into VOD server clusters which centrally accepts all the coming requests and evenly dispatches them to the servers in the cluster. Weighted Round-robin, Weighted Least Connections algorithms which commonly used in VOID cluster show low efficiencies, because they either do not consider the difference in performance between servers or do not consider the contents of coming different requests. In this paper analyzes and explores the load balancing technology of VOD cluster server, and puts forward a self-adjusted genetic algorithm. The experimental results are perfect.
