Abstract: This paper introduces a kind of comprehensive test system, according to the characteristics of video tracker, with one ARM chip as the control core, adopts the module design to integrate information and unify management through the 1553 B bus, realize the reset, start, communications, software debugging, unit testing, and other functions of pretreatment board, management board and algorithm board, performance indicators meet the all the test requirements of video tracker after validated.

Abstract: While radio frequency identification (RFID) is evolving as a major technology enabler for identifying and tracking goods and assets around the world, its security issues are also increasingly exposed. A Hash-based RFID mutual authentication protocol was put forward. The key was joined into the hash algorithm, and chaos sequences were used to update the key. The protocol enhances the security of the RFID system with low cost. Experiments show that the chaos system has the character of initial value sensitivity, which can be used to distribute and update the secret key. Safety analysis show that the mutual authentication protocol can solve security issues including eavesdropping, illegal access, masquerade, spoofing attack, position tracking.

Abstract: Because RFID does not require line of sight communication, low-cost and efficient operation with these outstanding advantages RFID are being widely used, followed by privacy and security vulnerabilities and other issues. Afterdescribe and analysis the facing security issues and the existing security protocols on the stage, proposed a low-cost RFID security authentication protocol based on hash function, this protocol use hash function and random numbers to ensure the safe and efficient control access between the tags and readers,and from the perspective of quantitative estimates the cost of tag. After setting up the idealized protocol model,by using the BAN logic formal analysis this protocol , and prove the security of protocol theoretically .

Abstract: When chip microcomputer and DSP sample much data in some certain environment, it is not possible to transfer the data with high efficient when using the old communication method because they call the top-level function. In this paper, a new communication method with VB and USB is proposed. It calls DLL function to configure and read/write from the hardware directly. With software improved, the method becomes better, the transfer speed can be 11.2Mbps, which is more fast than public 8.1Mbps, so the transfer efficient is improved by 38.3% with this new method.

Abstract: With the development of digital medical technology and Internet-related technology, the hospital's diagnosis and treatment become more and more inseparable from the work of modern digital imaging findings. The traditional way of medical image management services cannot meet the requirements of the new health care, so application of digital image management has become a top priority. With international and domestic regional medical information integration and sharing of system construction, imaging data center will serve as the core component of regional medical clinical information sharing system.

Abstract: In order to effectively increase the incursion features detection accuracy with high-degree camouflage in the network, this paper proposes a high-degree camouflaged incursion features detection algorithm based on BP neural network. This paper utilizes distributed components to collect and analyze the incursion data features with high-degree camouflage, and designs an incursion features detection proxy module based on BP neural network. This paper takes the protocol platform developed by some company in Zhengzhou city as an example to detect the incursion of malicious information and presents the detailed diagnose methods and procedures in which the accuracy can reach up to 93.7%.

Abstract: This paper designs a Vessel Remote Video Monitoring System based on internet protocol. The system uses positioning and network transmission technology to transmit real-time images of ships offshore to the server, to set up the client and visual monitoring ends. Ships monitoring personnel enter WEB monitoring platform with different permissions, to monitor and process ships image data through the network view, scheduling, monitoring terminals and other system modules. It also adds density ratio-based automatic alarm module to realize the intelligent early warning of offshore Ships density. Experiments show that the system has a better result to achieve vessel images' intelligent remote monitoring and early warning.

Abstract: The existing emergency virtual drilling simulation system is built on a set or more sets of static database. Case is extracted from the database or randomly generated from the database according to the condition system.It is basicly static data. The happening and development of the emergency is of great uncertainty, and it is constantly changing with the change of the environment and the rescue process. This article builds a set of dynamic database in the original virtual exercise simulation system, in order to join accident flexibly in the event processing node, and simulate dynamic environment conditions at that time in a timely manner. Data processing model that is by the combination of dynamic and static model can simulate disaster occurrence and development more realisticly and accurately.

Abstract: Traditional English classroom teaching can't meet the needs of the modern information society, the development of English learning resources website is extension and expansion of traditional English teaching. Database design is the basis and prerequisite for the website construction, this paper studies the Oracle database management system under the support of database design. First of all, based on the need analysis to design concept structure, and through the E-R model to express the design results; Finally, the characters, Numbers, time, large object and other five kinds of data type selection Then, on the basis of the clear logical structure design principles to design logical structure; In this paper, the research content, for the development of English learning resources website provides a feasible solution, has the vital significance to the English teaching reform, improve the quality of English teaching.
