Abstract: with the rapid development of information technology, put forward higher request to the enterprise management, enterprise resources constitutes the core content of modern enterprise information management, and logistics plays a more and more important role in the enterprise competition. In this paper, in order to reduce the inventory cost and improve enterprise market reaction ability, for the purpose of warehouse management based on supply chain, according to enterprise warehouse management problem, on the basis of using RFID technology, through detailed analysis of the actual demand of enterprise, it is based on B/S architecture for the design and development of a logistics storage system management system.

Abstract: Along with the computer technology, network transmission technology and the rapid development of digital signal processing technology, the application of real-time multimedia services based on IP packet networks more and more, including VoIP is a typical multimedia communication based on IP packet network business, has become the hot topics in the study of the current technology. As a network researchers, to research and development of VoIP technology is of great significance. In this paper, the VoIP key technologies were studied, especially the SIP agreement, then put forward and designed a kind of network communication system for smart phones based on VoIP.

Abstract: The fault-tolerant ability of an object-based storage system is an important factor that affects the reliability and usability of the entire system. Existing fault-tolerant methods either increase procurement cost, or impede performance. In this paper, we propose an I/O fault-tolerant method based on an application-level agent, which can perform fault-tolerance swiftly and efficiently at runtime by constructing the fault-tolerant agent’s execution engine. We consider a “disk full” exception as an example to further detail the implementation of this method. Experimental results confirm the method’s effectiveness.

Abstract: 60GHz wireless communication is a promising technology for multi-gigabit communication in future home networks. It brings possibility of achieving in-door high-definition multimedia applications with high-speed and low-delay experience. However, to maintain the network connectivity with 60GHz links, which are susceptible to propagation and penetration losses, is a major challenge. The quality and robustness of 60GHz links can be effectively improved by employing relay nodes or cooperative nodes in the network. In this paper, taking into consideration the directional transmission character of 60GHz system, we conduct performance analysis and simulations for the 60GHz cooperative communication system. Two cooperative forwarding approaches are analyzed and compared, and the optimal position of the cooperative relay node is proposed.

Abstract: The computer virtual reality technology is a new technology in recent years. It has been widely applied to various fields, and plays an important role in Sports. Analysis of the characteristics of virtual reality technology, its technical advantages, which are combined with the sports training, to improve the technical level of athletes in college students and the quality of training, make contribution for the athletics sports reserve talent reserve in China.

Abstract: How to quickly and effectively from the multiple candidate member of selecting optimal or approximate optimal components, so as to improve the success rate of component composition is a key problem. The basic idea of this article is based on tabu search algorithm; we design a tabu search algorithm, and prove the effectiveness of the proposed method.

Abstract: This paper mainly make a theoretical research and exploration on software quality assurance quality assurance improvement based on CMM process, with the educational software quality assurance model as an example. It elucidates the relationship between educational software process improvement and quality assurance, and explicits the importance of educational software development process improvement to the quality of educational software. Additionally, it discussed the establishment of educational software development model on the basis of the waterfall model of traditional software development, and construction of process quality management models and platforms based on CMM educational software process improvement.

Abstract: Accurate estimation of array’s phase center is of great importance in navigation, tracking and other aircraft and aerospace systems. In this paper first the effect of reference point on the phase pattern of a uniform linear array is studied and the phase center of the array is estimated. Then the effect of beamsteering on the location of phase center in phased arrays is theoretically analyzed, finally numerical simulations are carried out and the results are in good agreement with the theoretical analysis.

Abstract: The simulation shows a PPT presentation based on LabVIEW software of NI in this paper. The main VI program can be embed by sub-VI that dynamic simulate the process of PPT presentation, and use ActiveX technology to generate a real PPT document in LabVIEW.The simulation demo program save into the Microsoft PPT documents for easy archiving and other using presentations. The simulation results show PPT presentations be more vivid, making speech clearer.

Abstract: The Supervision System is one of the important components of the Construction Engineering Information Management. This paper proposed the system’s design with the Struts2 and MVC framework based on the android mobile platform. First of all, it gives the E-R model and data design in the system. Then, it gives the overall architecture of the system in which the android client uses MVC framework while the Server-Client uses Struts2 framework that is responsible for the separation of MVC and the jump of the business layer. Besides, for the communication protocol between the Client and the Server, it adopts the HTTP service and Socket service, and uses JSON as a data interchange format. In the end, the UI design of each module in the system is given.
