Rural planning is an important step in the urbanization construction and urban system perfection. Data integration of rural planning is the base of constructing a data center and application platform all over the country. A 7-layer framework of data integration of rural planning is designed in the paper on the base of analyzing the features of data of rural planning, such as distributed, of different frequency, from multiple sources and multi-semantic, referencing to the SIG 7 layers architecture and adopting the idea of service based of OGSA. Also the service mechanism and mixed deployment mode of data integration are studied in the paper in detail. The architecture has a characteristic of "general management, local autonomy", so it has the heterogeneous data integrated with great efficiency and high extensibility.

In order to make it simple to evaluate the vulnerability of explosives, the mechanical properties of the explosive loading source needs to be measured. By taking PVD films as sensitive elements, the design of the sensors, which can test the impact force, has been accomplished. The test system of impact force based on PXI has been constructed by means of charge integrators. In the end, the system got tested by 82 mm loading devices. And the pressure curve of the loaded 82 flat nose bullets were got as well. A method of impact force test is provided for the measurement of mechanical properties of loading source.

In this paper, based on the rudimentary knowledge of the nonlinear integrable couplings, we establish a scheme for constructing nonlinear integrable Hamiltonian couplings of soliton hierarchy. Variational identities over the corresponding loop algebras are used to offer Hamiltonian structures for the resulting continuous couplings. As an application, we use this method to obtain a nonlinear integrable couplings and Hamiltonian structure of the GJ hierarchy by using Tu scheme and the quadratic-form identity.

This study considered the urban congestion in the view based on the relationship between residential location, commute and urban transportation. Jobs and housing location perform the trend as geographical imbalanced with the increasing in commuting distance and time, and as a result, it has been considered as the main reason to the congestion, and planners take jobs-housing balance as an effective solution to the transportation problems. Even though, there is little evidence shows that jobs-housing balance makes significant effect, for the factors affecting where to live and work are complex. The study indicated that despite the residential location choices and commuting time and distance are closed linked, the effective solutions for urban transportation problems such as congestion should take comprehensive considerations including main factors in both short-term and long-term to improve the regional accessibility.

Reactors are widely used in chemical industry, pharmaceutical industry and many other industries. Advanced reactors aided with computer software can fully control the reaction process and record the whole reaction parameters. Compared with conventional software design, reactor control software design has its own specialty. In this paper. we introduce a design and implementation of the control and monitoring system for a multi-pot reactor. Also, we focus our attention on exploring the development of industrial software, discussing some typical problems encountered and providing corresponding solutions.

Grid infrastructure is a large set of nodes geographically distributed and connected by a communication. In this context, fault tolerance is a necessity imposed by the distribution as any node can fail at any moment and the average time between failures highly decreases. To improve the robustness of supercomputing applications in the presence of failures, many techniques have been developed to provide resistance to these faults of the system. Fault tolerance is intended to allow the system to provide service as specified in spite of occurrences of faults. To meet this need, several techniques have been proposed in the literature. We will study the protocols based on rollback recovery classified into two categories: checkpoint-based rollback recovery protocols and message logging protocols. However, the performance of a protocol depends on the characteristics of the system, network and applications running. Faced with the constraints of large-scale environments, many of algorithms of the literature showed inadequate. Given an application environment and a system, it is not easy to identify the recovery protocol that is most appropriate for a cluster or hierarchical environment, like grid computing. Hence there is a need to implement these protocols in a hierarchical fashion to compare their performance in grid computing. In this paper, we propose hierarchical version of these protocols. We have implemented and compare their performance in clusters and grid computing using the Omnet++ simulator.

In the face of new needs of the current network storage, the traditional DAS, NAS and advanced SAN network storage technology are analyzed, and the technical differences between the three technologies are compared. The redundant technology and main performance indicator system are analyzed by using system reliability theory, and thus derive that the RAID acting as the key and core storage node of the storage management systems still has some unideal situations. After an in-depth study of the optimization strategy, the data reconstruction and other key technologies of "RAID 50, small write" in the RAID design, this article provides an ideal realization algorithm, and designs a high-performance disk array system program using the two-processor and CACHE with a large capacity. Thus, the network mass storage based on SAN is achieved.

Semi-supervised data stream ensemble classifiers algorithm based on cluster assumption was proposed. Although traditional semi-supervised classification algorithm can solve incomplete label data sets classification problem, but it is an unsolved problem that how to use it in data stream environment and how to improve semi-supervised classification algorithm accuracy by using data stream characters. According to analyzing generalization of semi-supervised classifier based on cluster assumption, it indicates that increasing labeled data during training moment can improve semi-supervised classifier accuracy. Making use of this conclusion, a semi-supervised data stream ensemble classifiers algorithm based on cluster assumption was proposed.

This paper analyzes the higher vocational colleges' cooperative education model in China, which are divided into three basic types: model using service to seek cooperation. model relying on industry, model developing by the government's promoting. Four basic conclusions are reached in this paper. First, relying on the development of the industry to promote co-education is the basis: Second. achieving the approval by using the service and promoting development with the cooperation are the premise;Third, the industry and social economic development's needs are the starting point for personnel training and the purpose of cooperative education;Forth. Local government's attention and support are the ensurement of the sustainable development of cooperative education.
