Abstract: Dangerous Goods Logistics deals with the special kinds of objects, i.e. the hazardous article, which tend to be corrosive, spontaneous combustion, flammable, toxic, explosive and likely to cause some hurts and damage during the process of storage, transporting, handling and delivering and need to be treated extremely careful to ensure the special protection. It has to be implemented not only safely, but also to meet the needs of customers at the lowest cost. RFID (Radio Frequency Identification) is considered to be an advanced technology which offers the dangerous goods logistics a secure, scientific and effective means of management.

Abstract: Through designing the evaluation index system, the fuzzy comprehensive evaluation model of the college classroom teaching quality is constructed based on the theory of fuzzy mathematics in this paper. The empirical results show that the model is an effective assessment to evaluate the quality of college classroom teaching and has good scientificity and practicality.

Abstract: The in-class interaction system (clicker) has been used in the physics class recently in China. It dramatically changes the normal lectures in large classes and enhances the class interaction. In this paper the improvements of this system on the traditional physics teaching are summarized. We illustrate how to integrate this system to the physics class to design teaching process. Some suggestions about teaching effectively and assessment of this system are also given.

Abstract: Since powerful supervision on the mobile value-added services lacks nowadays, the mobile market goes in to a tendency of being rather chaotic. This research will analyze the behavior of both the service providers and mobile operators, with game theory model to be established. Moreover, the Nash Equilibrium will also be considered which shows that the costs and extent of the mobile operators supervision besides the penalty for the service providers being caught will definitely influence the probability for service providers to violate the rules. On the other hand, the proportion of illegal gains shared by mobile operators and the penalty degree for service providers may be the main factors that affect the mobile operators supervision choices. At last suggestions are made on the service providers strategic choices.

Abstract: This paper presents a system architecture through a new type of strategy for web-page tamper-resistant. The new strategy emphasizes the following points: by using of file filter technology timely find out and block the malicious tampering so that the illegal malicious tampering is prevented; the tamper-resistant module and digital watermark module are distributed in two different servers and the servers are separated by a firewall to strengthen the overall security of the system; to ensure the security of the tamper-resistant process, it is necessary to deployment a single chip machine to protect the tamper-resistant process.

Abstract: Geographic Information System is widely used in different fields and it has different backgrounds and models these are introduced briefly in this article. Based on the analysis of development background, application and the related trends of development both at home and abroad for pipe network system, some problems are indicated, such as, building the pipe network geographic information system needs to grasp the key technology, including component technology, object-oriented design, databases and pipe network modeling technology, according to the data characteristics of gas pipe network and using MS Windows 2000 (Advance) Server or UNIX as operating system. The overall design plan of Daqing gas company pipe network information system based on the way of Web is put forward and selecting Windows 2000 Professional as client computing operating system for running the ArcInfo 9.x application program and using other geographic information system software to build the geographic information development platform that gives priority to the ArcGIS of ESRI company. The management method of geographic information system is mainly database, elaborating the implementation of all systematic functions and the management process of data and corresponding software and the development of user interface, the access to the database are finished as well. Design of user-interface is practical and convenient, which has the characteristics of easy and flexible operation situation and high visibility. Therefore, it indicates the application of geographic information system technique is to lay a solid foundation for the standardization of enterprises, in the meantime, it can effectively promote the urban construction and economic development.

Abstract: With research and development of the telemedicine and the electronic patient information, the remote wireless health monitoring system is facing the challenge of patient privacy protection. This paper proposes an effective patient privacy protection protocol, which protect the privacy of patient information with the encryption algorithm based on identity-based cryptography (IBC) and digital signature during the process of sending, receiving and accessing the patient information, and resist the path monitoring attack of identifying the contact between patients and doctors with the network stream analysis.

Abstract: As a new industry in China, cold-chain logistics has some characteristics including high timeliness and short shelf-life. It is considered to be available to improve the efficiency of operation and management of cold chain logistic by the sensible usage of advanced RFID technology. The paper studies the necessity and feasibility of the applications of RFID based on the discussion of process of cold chain logistics, which covers manufacturing, stocking, transportation, delivering, and marketing of the cold products, in order to guarantee the quality of the cold chain and publics safety.

Abstract: In recent years, the strong evolution in automation, the significant advantage has been taken by ceramic industries. All production phases have been addressed through various technical innovations, with the exception of the final stage of the manufacturing process. Mostly, manufacturers have to apply artificial quality inspection at the final stage. It is labor intensive, slow and subjective. This paper proposed an approach of automatic quality inspection for ceramic product, system schematic and method are proposed, and it can easily implement in hardware system. Experiments in lab have been done to test the method.

Abstract: t is necessary to establish a remote wireless monitoring system for the heading face of coal mine because of the risk of gas outburst and water inrush. This paper introduced a remote wireless monitoring system for heading face of coal mine based on wireless mesh network. The key technology is that the wireless backhaul link of this wireless communication system must remain high bandwidth and low latency after multi-hop in order to support video transmission because the laneway of coal mine is narrow and long. We used the technology of multi-interface multi-channel to design a 2-interface 3-channel backbone network for this wireless communication system. Each node of this backbone network is equipped with two interfaces, and three orthogonal channels of channel 1,6,11 provided by 802.11b/g are used. Compared to single interface single channel chain network, the 2-interface 3-channel wireless mesh backbone network has high throughput and low end to end delay while using appropriate channel allocation algorithm to make the channels of adjacent links non-interfered.
