Abstract: At present ,People usually uses visual report design components to simplify the report design, But this means reducing the reusability of software development and working efficiency .Aiming To raise the efficiency and reuseability of software developing ,This paper introduces a new parameterzed Report Builder idea, and also gives the concrete design and implementation for this report generator based on .NET component technology . In this paper, the basic design idea, primary data structure, format calculation and printing algorithm for the report generator are also discussed in detail. And an applied instance of the generator is also given in this paper.

Abstract: Proposed a new index structure, named MG2R*, can efficiently store and retrieve the past, present and future positions of network-constrained moving objects. It is a two-tier structure. The upper is a MultiGrid-R*-Tree (MGRT for short) that is used to index the road network. The lower is a group of independent R*-Tree. Each R*-Tree is relative to a route in the road network, can index the spatiotemporal trajectory of the moving objects in the road. Moreover, moving objects query is implemented based on this index structure. It compared to other index structures for road-network-based moving objects, such as MON-Tree, the experimental results shown that the MG2R* can effectively improve the query performance of the spatio-temporal trajectory of network-constrained moving objects.

Abstract: Based on Web of mine equipment maintenance management system,mainly to solve the mining equipment safety inspection,repair and test equipment,the existing problems of mine machinery and equipment maintenance is lack of effective management means information. Based on the introduction of mine equipment maintenance management system using database technology, network technology and the Web,this paper expounds the mine equipment maintenance management system structure,function,design,functions.

Abstract: In wireless multi-hop networks, the quality of service provided by the system heavily depends on the cooperation between nodes. However, nodes are reluctant to cooperate with each other to save their limited resources. This tendency will put a limit on the application of the current wireless multi-hop networks. Therefore, game theory, which can analyze the strategic interactions among autonomous decision makers, becomes an ideal candidate to solve the above problem. In this paper, we first introduce the basic concept of game theory. Then, the game-theory-based routing algorithms for wireless multi-hop networks are investigated in detail and their characteristics are compared. Finally, we give the future research directions and concluding remarks.

Abstract: The agricultural information on the internet become more and more, it is very difficult to search accurate related information from such different information, in order to improve the efficiency of information retrieval on the internet, the intelligent searching technology of agricultural information based on ontology is proposed. The paper firstly introduces research on the agricultural ontology and information retrieval, and takes agriculture domain knowledge as research object, analyzes the characters of agricultural domain knowledge and semantics retrieval, then uses the agricultural ontology to make the structure of agriculture ontology knowledge, and constructs the related agricultural knowledge ontology and knowledge base, implementing the intelligent searching of the agricultural information. The results indicate that the application of agricultural ontology technology in the agricultural information retrieval not only achieves the intelligent retrieval of agricultural information, but also greatly improves the accuracy and reliability of agricultural information retrieval.

Abstract: In order to provide intellectual support for the construction of model resource of tree growth management, the paper carried out research on ontology and knowledge base technology, and the tree growth management resource information and ontology knowledge base were regarded as research target, which applied the ontology knowledge organization, then used semantic languages and resource model to study tree growth management resource knowledge base, discussed the acquisition, reasoning and other methods of tree growth management resource information. The practice has proved that resource information model of tree growth management based on ontology can acquire more parameters of tree growth management resource than traditional methods, which can provide sharing platform of resource information for tree growth management and contribute to construct the resource information model of tree growth management.

Abstract: an improved method is proposed to skip the look-ahead period in this paper. The improved method uses the autocorrelation algorithm to calculate the Linear Prediction (LP) coefficients and then the LP coefficients are employed to extrapolate new samples for replacing the look-ahead samples. To evaluate the quality of this method, perceptual evaluation of speech quality (PESQ) and the A/B listening test method are designed for the objective evaluation and subjective evaluation. The reconstructed quality of the modified method is near to the original AMR codec, at the same time, the delay of the improved method is lower 5ms than the original method.

Abstract: In order to build a more user-friendly, intelligent IoT where interactions between Human-to-Human, Object-to-Object, and Human-to-Object coexists, real-world objects are assigned a social network identity on current SNS. Under this scenario, the contexts of the real-world objects become more complicated since it contains both social attributes and physical attributes. This paper proposed a context-aware middleware for infers the contexts of real-world objects in SNS. The deduced context of the object is generated from the physical contexts, which retrieved from WoT infrastructure and social network context from SNS, which results in the quality of the context more dependent to the real state of the object. Then, services or behavior will be triggered by the middleware after the reasoning process. Implementation on the MagicHome project will illustrate the feasibility and reasonability of middleware in a smart home scenario.

Abstract: Nowadays, smart phones and tablets have been getting more and more popular. Many applications in various mobile platforms can provide location based service to users but seldom take personalized information into consideration which is usually important for some kinds of applications. In order to solve the popular problem of searching a available classroom on campus to do individual study and provide students with personalized services, in this paper, we design and implementation of a context-aware based available classroom searching system-CACS, which can not only use the users location information but also takes personal preferences into consideration to make this type of applications more convenient and personalized. In this paper, the system model is constructed and some key issues and methods such as weigh based classroom evaluation algorithm are proposed. The prototype system shows that this system can benefit users with good experiences.
