Collaborative Virtual Environment(CVE), which is the high performance combination of Computer Supported Cooperative Work(CSCW) and Virtual Reality(VR), makes it possible to support people working collaboratively in a visual way. Based on the conception of CVE, this paper presents an architecture on Internet for cooperative design supported by Web Services, and discusses the related key implementation...
In applications of personalized recommendation, user similarity of common clustering algorithms only considers user relationship without considering relationship between users and items, the similarity above reduces the accuracy of clustering, making it difficult to find similar users, and the same with item similarity. This paper improves the distance function of data clustering algorithm by Hamming...
In order to improve the efficiency of web service composition based on traditional heuristic algorithm, this paper focuses on the web service composition method by merging genetic algorithm(GA) and ant colony algorithm(ACA). Firstly, this paper transforms web service composition into finding a QoS global optimal path, then obtains the initial pheromone distribution of ACA by running GA, finally works...
For the issues of the existing method in the selection of web service blindness and customer service evaluation incredible, this paper presents a web service selection method based on credible user recommended and QoS. Firstly, searching for recommended user from the credible user group, distinguish the current user into the new user or old user, then adopt different recommended algorithm to form...
Nowadays, most people rely on traditional data mining techniques to address business affairs. But data mining is proposed for the large amount of data, lack of effective methods to process the data that is little or incomplete, or is overall complex but has a strong regularity at a certain time or space. Grey system theory is the new method to research less data, poor information and uncertainty problem...
Process control is the important and difficult part of CPU management education in operating system. In this paper, we discuss a teaching methodology which is based on “theory and practice, basic and promotion” according to the characteristics of the teaching contents. The teaching contents can be transformed from abstraction and simplicity into concreteness and integration by this methodology. The...
This paper proposes a vehicle-oriented forecasting rules algorithm based on the Data mining Multi-dimensional association theory, according to the task scheduling experiences, which made the system to forecast the data flows and to raise the ability of the dynamic priority algorithm, to the data jammed situation where data flows is huge and transfer networks are not planned properly. Experimental...
Google Map is widely used as a platform for a number of applications because of providing the public satellite maps all over the world, but it is hard for user to add vivid interactive applications on website based on Google Map (GM). The reason is that GM can not provide many features of API while allows the application to mix its content with it before. In order to interact with GM instantly and...
As a large information services system based on RFID (Radio Frequency Identification) technology, VDSI (Vehicle Digital Standard Info-source) system needs to deal with a huge number of data everyday. As a result, the query speed is one of the most important facts in the design process. The paper introduces a means that optimize the database by means of indices, which can indirectly improve the efficiency...
The information source has been a bottleneck problem which troubles the vehicle digitalization process for a long time. With the rapid growth and wide range of adoption of Radio Frequency Identification (RFID for short) technology provide a new viable solution for the problem. However, with the adoption of RFID technology, the information security problems must be solved. This paper discussed the...
For the time being, one of the most important problems of vehicle digital standard info-source is that the capacity of the memory is small but the number of the information that need to be stored in it is large. The paper first introduces the background of vehicle digital standard info-source, and then the paper analyzes its functions related with the vehicles and designs a memory resource scheme...
In this paper, the advantages and disadvantages of the gray variance directional image segmentation methods were analyzed. On the base of gray normalization, a new approach to segment the fingerprint images was proposed using the normal distribution model of the fingerprint image graypsilas character. This approach makes use of the gray characters of the local and global images. Meanwhile, it has...
