Abstract: The 6 degree of freedom glide motion equations of the unmanned underwater vehicle (UUV) was built. Than the scene simulation system of AUV was designed based on the Creator and the Vega Prime. The results show that the simulation system simulates well the 6 degree of freedom glide motion of the UUV, and some key technology of the UUV scene simulation system was solved.

Abstract: This paper chooses equal-rectangles dynamic-layout algorithm as die-steel intelligent-layout algorithm, combines with drawing algorithm and .NET visual component to convert three-dimensional entity into two-dimensional model by coordinate rotational projection. We realized intelligent-layout and simulated the process of die-steel cutting in three-dimensional perspective effect. This system offered autonomous-layout mode and intelligent-layout mode. The former simulated the cutting according to producer’s experience. The latter simulated the cutting on the basis of producer’s requirement by intelligent layout algorithm. The application of this system enhances the market competitiveness by increasing the die steel utilization rate and decreasing the enterprise production cost.

Abstract: In a 1-out-n oblivious transfer model, the sender sends n messages to the receiver. But the receiver can only get 1 message from the n messages, and the sender does not know which message the receiver has gotten. In this paper, we proposed a multiple-use 1-out-n oblivious transfer protocol based on threshold idea. It is more efficient than Naor-Pinkas protocol[1] and Tzeng protocol[2].

Abstract: The military conceptual model (MCM) provides an unambiguous and credible reference for the development of the combat simulation system. According to the characteristics and regularities of the tactical decision-making (TDM) process, this process is divided into five abstract stages, which analyze the modeling method of the simulated military conceptual model in detail. This method reduces the common attributes and action of the TDM entity to that of a super one, which avoids the appearance of a multi-inheritable complex construction. Then the super TDM entity is analyzed so as to obtain a description of its properties and action. By summing up the functions of the TDM simulation entity, it can point out that this modeling method has very strong feasibility.

Abstract: Aiming at the knowledge representation problem in emergency logistics, this paper presents an ontology-based modeling framework for emergency distribution decision. The suggested ontology model includes the meta-ontology, the domain ontology and the upper relationship, and it can be extended to meet the various requirements in emergency logistics application. As an illustrative example, an instance of Location Routing Problem (LRP) is defined using proposed ontology model, and a rule-based reasoning experiment is developed with Jena. The result of experiment demonstrates the effectiveness of the ontology modeling framework, which can be used as an important complement to traditional optimization methods for emergency distribution decision.

Abstract: Security is an important index in the design of information integrated system. Combined with the development of an information integrated system, the security design of database system and network of the Web-based information integrated system are researched. The safety management methods and implementation measures are presented, which have certain reference value in the actual execution process.

Abstract: According to the shortcoming of the color petri net, we have proposed a new method named multi-grade color petri net in order to satify the need of analyzing the hardware design. We for the first time use this method to analyze hardware design. This model can accurately reflect the complex environments of the system and avoid the difficulty occurring often in founding accurate mathematics model by using classical research approach.

Abstract: A new model is proposed based on logic Petri nets for web service clusters. The service parameters of a cluster are unified and logical expressions are introduced to represent the indeterminacy of service clusters. A service cluster can be used as an integrated unit and parameter matching can be decided based on semantic similarity and logical inference in a service cluster. Some algorithms of web service discovery and composition are given based on logic Petri nets, and the redundant services are removed from service compositions by a backward method. The availability and efficiency of the proposed approach are illustrated by the experiments with large repositories of different sizes.

Abstract: In the scene of disaster rescue, there are usually many potential hazards. How to guarantee the safety of the Rescue Personnel and the rescue efficiency is a problem that deserves our concern. From the perspective of rescue security, this paper explores a new program that adopts ZigBee technology in disaster rescue. By making use of ZigBee technology's features of high-reliability and low-complexity, it can make the gas acquisition module, image acquisition module and human detection module to form a wireless sensing probe network and then realize the environmental monitoring of disaster site and disaster victims searching and rescuing. In this way, it can overcome its previous shortcomings, such as poor real-time detection network, difficulty in wiring, etc. and thus to achieve the purpose of efficient early warning and rescue.

Abstract: With the increasing mass data processing and requirement on interactive concurrency, parallel computing became the popular issue as one main method for improving service capability. The content and research objective of parallel computing were introduced, and the parallel computing based on divide-and-conquer for solving rectangle packing problem was designed with two processors, and achieved. The efficiency and quick solution of parallel computing were verified through the comparison with serial algorithm as well as analysis.
