Abstract: In Multi-Agent system, the communication among the Agents is the basic problem. The Agent communication language design, especially for large database operation, has been the important part for improving the Multi-Agent system performance. Based on the Multi-Agent large scale database operation, this paper extends the KQML's Primitive for Agents communication. The extended KQML's Primitive can improve the Agent communication performance and the database query performance.

Abstract: Based on the concept of digital citiy, futher explained the concept of society economy environment (SEE); Combining GIS and network technology, this paper proposes the framework of the city SEE information inquiry system. And based on the spatial analysis functions in the spatial query and the amount of operator functions of GIS, describes the functions of the system.

Abstract: This article mainly aims at the problem of the video text font size, achieved a algorithm of multi-scale corner text detection, and combined with the characteristic of word usually has the same color, even more precise positions the text area with color clustering way.This algorithm not only detect the game scene, video ads and video news kind of information in words, but also be used for the natural scene of the text of the detection positioning.Finally, test a public data sets, and the test results show that the proposed method can detect and positioning video the text in the complex information.

Abstract: A maximum-meet user’s individual needs integration model was presented in this paper, which integrated information integration thinking, Web3.0 with open platform. The model embedded Service-Oriented Architecture (SOA) framework realized the information integration. Then combined the OpenID ,OAuth, and role-based access control (RBAC) achieved single sign-on and authorization system; finally, based on Maps API Mashup applications realized the interaction between the LAN Web information and maps. The model has the advantage of friendly interface, strong replicability, and high security.

Abstract: This paper dissertates the application of Virtual Reality Technology in the training process. Virtual training system has more advantages than traditional training system. The design of virtual training system based on PTC DIVISION Mockup software, position tracker and 3-D mouse is proposed. The system is divided into two parts: directing part and operating part. The directing part is mainly implemented by Functional Simulation structure in DIVISION Mockup. The operating part is realized by virtue of the third-party plug-ins, which connects peripherals with the virtual reality system. This system is applied to the training process of hydraulic pump cart’s assembly and disassembly. More immersive training effect is obtained in this system. The goal of reducing training costs and improving the efficiency of training can be achieved in the virtual training system.

Abstract: Support Vector Machines (SVMs) is a new technique for data mining. It has wide applications in various fields and is a research hot pot of the machine learning field, but, being applied to handling large-scale problems, SVMs needs longer t raining time and larger memory. It’s an effective way to solve large scale data processing in text classification with multiple classifier systems composed by multiple support vector machine classifiers. Based on the analysis of traditional parallel algorithms, this paper proposes an improved algorithm based on multiple SVMs. The experimental results indicate that the new algorithm works well in precision and recall rate in the condition that the speeds of classification increase remarkably. Compared with traditional algorithms, the classified accuracy is lower but is within the range for acceptance.

Abstract: The warehouse is the major place for storing the goods in the logistics operations. And the operation flow of warehouse has a direct impact on the logistics efficiency and benefit. Otherwise, logistics simulation technologies have been widely used in the field of logistics. It verified the validity and rationality of the logistics planning in a certain extent. This article use Flexsim as the simulation’s tool, and take X Company as the research object. And we used Flexsim to establish the simulation model of X company’s warehouse. According to simulation results, we analyze the bottleneck problem in the warehouse operation. Then put forward some suggestions for improvement and optimization.

Abstract: For XML documents, existing keyword retrieval methods encode each node with Dewey encoding, comparing Dewey encodings part by part is necessary in LCA computation. When the depth of XML is large, lots of LCA computations will affect the performance of keyword search. In this paper we propose a novel labeling method called Level-TRaverse (LTR) encoding, combine with the definition of the result set based on Exclusive Lowest Common Ancestor (ELCA),design a query Bottom-Up Level Algorithm(BULA).The experiments demonstrate this method improves the efficiency and the veracity of XML keyword retrieval.

Abstract: The interface design of software used on Home Appliances targeted at satisfying passenger's physiology and psychological needs when operating the machine to the maximum extent is a complicated synthetic topic which embracing ergonomics, visual communication design, user experience design, behavior psychology, cultural studies of the consumer, optics and Chromatics and so on. So, it is very difficult for us to find a unified criterion which can be used to estimate the interface design of the software used on Home Appliances. In order to improve science and objectivity of the evaluation process, this paper established the evaluation index system centered on the user experience firstly. Then identified the weight of each index used AHP. Furthermore, constructed the evaluation analytical model used the Gray Disaster theory. This method effectively overcomes the subjectivity and arbitrariness in the evaluation process. Finally, the prototype system of the software has been developed to verify the validity of the method.

Abstract: In this paper, a virtual machine migration policy for large scale virtual desktop service is proposed. Usually a virtual desktop service is composed of several physical machines, each of which is running several virtual machines. Sometimes virtual machine should be relocated to other physical machine when load balance over the system lost. In this situation, a management server must answer two questions: who should be relocated and where is the destination host The proposed migration policy in this paper is three kinds. We suggest the best policy from the viewpoint of user and system. By experiments, we show that our policy reduce user connect time and increase the number of concurrent virtual machines.
