Abstract: A video conference system based on SIP is introduced in this paper. It elaborates the structure and design of the system's functionality. The meeting control center of core part of this system is introduced in detail, and the specific implementation methods and control flow is mentioned. The system uses a hierarchical design idea. It is an extension of a strong multi-party video conferencing system solution which utilizes more mature network technology and encryption technology to ensure t real-time and safety of the system.

Abstract: The development of e-commerce in the Pearl River Delta Region has benefited from its sound environment. It is one of the important measures to develop e-commerce forward a new industrial road, which can promote IT-based industrialization, change the mode of economic development and improve the quality and efficiency of the national economy. This paper presents the current situation of e-commerce development in the Pearl River Delta region, analyzes its development advantages and tendency, and concludes with some existed problems and the further development countermeasures of the Pearl River Delta Region e-commerce.

Abstract: In this paper we provide a determined key distribution protocol using orthogonal product states in which people can share a predetermined string as the key. The fundamental principles of quantum mechanics guarantee that the protocol is unconditionally secure. There are no entangled states or complex quantum operations needed in our protocol. So it’s easy to carry out in practice and robust against possible noise and attacks.

Abstract: A hardware-in-the-loop (HIL) simulation platform in use of windows operation system was successfully established based on general industrial PC combined with an external timer. The following HIL simulation process of missile control system indicated that the novel platform could not only satisfied the real-time requirement of HIL simulation, but also is low-cost and universal, which could provide a convenient new choice in the similar applications.

Abstract: In order to save mobile phone memory and improve the rate of loading resource, which could improve the user experience about the application, this paper put forward a kind of asynchronous loading mechanism which was optimized by combining SoftReference and LRU algorithm. Further more, it realized an application using asynchronous loading resources to verify the mechanism on the android platform. This mechanism offers a strong support both in theory and technology to improve the function of smart phone.

Abstract: To realize the management and reuse of the knowledge of straightness verification, the ontology theory is applied in the knowledge base system of straightness verification. The system is divided into three layers: domain layer, inference layer and application layer. The ontology of the straightness verification is established for formal description of the conceptions of straightness verification and the relationship among these conceptions. Related axioms, rules of straightness measurement are given out according to related standard documents. Finally, an application platform is provided for the digitized realization of the straightness verification.

Abstract: By analyzing and extending 802.1X protocol, this paper proposes a scheme of secure terminal access on the internet of things. The scheme consists of three components: an authentication client, a switch supported 802.1X protocol and a radius authentication server. This paper proposes the work flow after explaining these components respectively. The test results show that the scheme satisfies the functional requirements of terminal security access on the internet of things.

Abstract: The groundwater is a kind of necessary and precious resources. Because of continually increasing demand of water resources in various industries and position decentralization of water wells, management of water wells become more and more complicated and important. The conception of “Smart Water” is raised according to “Smart Planet” for the first time. The paper put forward a kind of monitoring and management system based on the architecture of internet of things. The system includes sensor layer, transport layer and application layer. The paper put forward the key technologies of sensors, wireless networking, application platform etc. At last the paper introduces some application of the system in monitoring, calculation, controlling and management.

Abstract: This paper in mainly introduce the data quality, from the data schema to instance. According to the data schema and instance analysis, find out the problem of data quality, and as to the problem, use the relation method solving it. The aim is to improve the data quality

Abstract: Abstract : The power of large and interactive surface of Multi-touch Table lies not in the technology as an end but more the means of enable multiple users to efficiently process visually oriented data. This technology offers different orientations for multiple users which also give advantage such as more than one user to input commands directly to the display surface, either via a pen-based device or directly with their fingers. The aptitude to interact directly with one’s manipulation of data provides opportunities for developing richer, more natural of hands-on and further the neutrality of human-computer interaction metaphors. Touch-enabled surfaces are becoming used in various setting such as in education, military and business. It is situated in a variety of work and public places to accommodate sharing information and enriching the interaction on the interface. Adding to this point is that the technology offers a large interactional surface and makes it simpler to support collaborative work. This paper reports on preliminary results from this ongoing research on military decision making, including the significance of multi-touch table application in diversity of domains, namely military and education and last but not least is the fundamental characteristics of Multi-touch Table user-interface functionalities that needed in the development of Multi-touch Table content.
