An emotion based spatial design technology can change some factors with which a user may affect emotion, and enable a user to design a desired space. In composing an actual space, the production period may be reduced and the quality of produced contents may also be ensured. An emotion based digital spatial design can either help a user design an emotional space by utilizing a basically constituted...
According to the research of the theories, concepts and methodology of Web and DSS, this paper presents a new design method of DSS based on XML technology. The paper describes the developing process of the DSS of logistics distributing center based on XML. The problems have been solved that how data is transferred and exchanged between the DSS of logistics distributing center, logistics ERP and users...
OPC, the data integration middleware in the industrial control field, defined an industry standard for exchanging data between field devices, control systems and other applications. XML, as a W3C standard, was open and platform independent and gave another way to describe and exchange structure data between applications. The combination of OPC and XML, provides vertical integration from floor layer...
A distributed real-time production supervisory designing conception based on OPC and Web technique is presented. The OPC technique and its application in the DCS of cement enterprise are introduced, the seamless connection between the application and plant, and the Web distribution of production data are realized.
This paper presents the implementation of an automation laboratory with virtual, remote, real-time and simulated experiments for a workstation (body feed-positioning station, part of a Flexible Manufacturing System FMS-200) and the benefits of the application of Virtual Reality, Telematics and 3D simulation in Control Engineering education. Beyond the theoretical training based on the Internet, practical...
In this paper, a simulation system for turn-milling center is designed by VRML and Java/JavaScript based on Distributed Virtual Reality (DVR). The system overcomes the disadvantages of traditional expensive CAD/CAM software and reduces the volume of the machine document which is convenient for transmission through the Web. The system includes movement demonstration and machining simulation by inputting...
Real-time streaming over the Internet has become an important way of delivering video data to the user, but packets may be lost because of the unreliable channel. In some real-time video applications such as video conference and video surveillance systems, time delay and Quality of Service are both very important. This makes the use of error resilience and flow control techniques necessary. In this...
Distributed denial-of-service (DDoS) attacks are a major threat to availability of Internet services and resources. We present an adaptive control mechanism that utilizes the Shewhart's control charts based-on network connection to aid in handling DDoS attacks. This mechanism is designed to prevent incoming traffic from exceeding a given threshold, while allowing as much incoming, legitimate traffic...
In order to solve security problems in web-based information systems in the large-scale distributed environment, we design a comprehensive security policy. We realize the single entry mechanism of multi-system access by using the single-sign-on, create identity authentication mechanism of high-reliability and security based on China's second-generation ID card. We also propose the cross-domain setup...
With the development and widely used of Internet and information technology, the Web has become one of the most important means to obtain information for people. According to the Web document classification and the theory of artificial neural network, a Web classification mining method based on fuzzy neural network (FNN) is presented in this paper. We construct the structure of fuzzy neural network...
