Abstract: This paper introduces a new technology using a new mathematics model to solve the blending problem of two or more kinds of minerals, which grades are very different even in orders of magnitude, and creates a blending system which can produce an optimal program of blending automatically using a feedback process based on Surpac, a mining software, and achieves a real time truck dispatching system finally. All of above can improve quality and quantity of the minerals blending stably, that has been proved in practice. According 2001s record, this system had the Cu grade amplitude down from 10.54% to 3.72% and the Mo grade amplitude from 6.49% to 3.11%.

Abstract: Data replication is adopted to improve data access performance in cloud computing environment. When different sites hold the same data resource, there are significant benefits while selecting the best one. In this paper, we propose a new replica selection algorithm based on prediction. Analyzing the factors infecting replica selection, The grey system theory is utilized to help predicting the data response time on the basis the GM(1,1) grey dynamic model; Meanwhile the Markov chain is applied to achieve state transition probability matrix to predict the reliability of replicas in the form of probability by the system state classification. The simulation results show that in our replica selection model, the prediction is valid, helpful to selection decision, and is able to achieve load balance between nodes holding replicas.

Abstract: Cloud-based digital library has achieved an efficient storage of massive digital resource, reduced the cost of management and maintenance, improved the sharing of information resources between digital libraries, and provided a convenient and rapid service for the users. Cloud storage architecture has the features of high reliability, high performance, high expansibility, etc. In order to ensure the security of information resources and the continuity of information service in Cloud-based digital library, the paper constructs disaster recovery system model of cloud-based digital library to ensure data security and business continuity. The model has dynamic scheduling, standard access interface, dynamic memory management and other functions.

Abstract: Currently in the application level of Internet of Things (IoT), relevant data format standards are very complicated and every relational subject goes his own way. To solve this problem, this paper, from the view of XML and G/S model, started with the relationship among Internet, Semantic Web and IoT and then put forward the way of building the IoT data format standardization system. The IoT data format standardization should be based on XML for syntax and on G/S model. Data Exchange Standards System of the IoT should adopt XML as its grammar format. Finally, the system (base on MSML) with a specific application is illustrated.

Abstract: WebGIS is one of the key technologies in the process of Digital City informational, networking, intelligent and visualization. This paper mainly introduced the concept of WebGIS and digital urban planning at first and then in detail interpreted the design, structure and functions of the model system of digital urban planning system based on WebGIS, and carried on a preliminary test, finally discussed the application prospect of WebGIS in the urban planning area.

Abstract: In order to improve the efficiency of designing monitor system software and modeling with UML, the UML application of software system modeling was researched in theory and practice. The whole process is divided into four steps, which are the global analysis, the local analysis, the global design, and the local design, and the GUI of the system is described at last. A distributed highway monitoring system is analyzed and designed by UML.

Abstract: This paper analyzes Web clustering firstly, then proposes to describes the object using binary property for users clustering in Web clustering. Makes the time property Binaryzation using Zipf's Law, then clusters the object using ROCK Algorithm. Experiments can prove that the work for clustering is well.

Abstract: The polymorphism is the one of the main features of the object oriented program. The compiler determines the uniqueness of polymorphism by dynamic binding. In a static source code, there will be one function calling point corresponding to several called functions. As the consequence, there will be many redundant function calling paths. It is the key to improve the efficiency of the path coverage test based function call graph with control logic determining the uniqueness of polymorphism. This paper analyzes the feature of the polymorphism in C++ and proposes an algorithm to determine the uniqueness of polymorphism statically in C++. The algorithm can find the unique called function from the several called functions without running the program. The result shows that the algorithm can obtain the unique called function correctly and eliminate the redundant paths. It improves the testing efficiency and reduces the testing cost.

Abstract: Website architecture model is introduced in this paper as a whole, it mainly illuminates design process of three layer architecture model, states characteristics and advantages of layer architecture, demonstrates main points and difficulties of every layer design in detail. The model of website design can be reused by applicating object-oriented concept to website design.

Abstract: Because features of Chinese short text are different from long text, current text classification technology of long text classification are not suit of short text classification. This paper summarizes features, various methods and Application for Chinese short text classification, and pointes out their advantages, disadvantages and applicability scope. Establishing Open data set and unified framework standard are two main Problems and further research directions.
