Abstract: We describe the conclusions of a technology and communities survey supported by concurrent and follow-on proof-of-concept prototyping to evaluate feasibility of defining a durable, versatile, reliable, visible software interface to support strategic modularization of test software development. The objective is that test sets and support software with diverse origins, ages, and abilities can be reliably integrated into test configurations that assemble and tear down and reassemble with scalable complexity in order to conduct both parametric tests and monitored trial runs. The resulting approach is based on integration of three recognized technologies that are currently gaining acceptance within the test industry and when combined provide a simple, open and scalable test orchestration architecture that addresses the objectives of the Automation Hooks task. The technologies are automated discovery using multicast DNS Zero Configuration Networking (zeroconf), commanding and data retrieval using resource-oriented Restful Web Services, and XML data transfer formats based on Automatic Test Markup Language (ATML). This open-source standards-based approach provides direct integration with existing commercial off-the-shelf (COTS) analysis software tools.

Abstract: The line-of-sight (LOS) stabilization control is required to isolate LOS from the movement and vibration of carrier and ensure pointing and tracking for target in electro-optical tracking system. In this paper, a fractional-order PI (FOPI) controller is applied in the design of stabilization loop of LOS stabilization system based on the analysis of the fractional calculus theory. This controller exhibits excellent performance even in presence of nonlinearity and uncertainty. Details of this controller along with the performance comparisons between FOPI and conventional integer-order PI (IOPI) are presented. Simulation results indicate that the FOPI controller can improve the carrier disturbance rejection performance of LOS stabilization system.

Abstract: A whole image of a reconnaissance well with acoustic time, acoustic amplitude and video can be obtained by an image logging apparatus. The results (feature dip/strike and azimuth, joint density analysis, synthetic cores, feature stereograms, rose diagrams, deviation plots of borehole) of image logging are displayed in the form of well explained figures, intuitionistic, vivid and easy to be analyzed. Image well logging technique has played an important role in oil and gas exploration, but its application in construction engineering is still in its initial testing phase. The hardware constitution and the basic principle of RG image logging apparatus system are simply introduced, and its application effects in transmission cable tunnel project are also displayed in this paper

Abstract: Traditional text classification algorithms have vital impact on information filtering. However, their performances were confined to a large extent in terms of the massive data set. This paper proposes an approach using MapReduce-based Rocchio relevance feedback algorithm, which improved the traditional Rocchio algorithm in the MapReduce paradigm, to resolve the problem of massive information filtering. The experiments on Hadoop cluster showed an effective improvement in performance by using the new method.

Abstract: In order to realize instant and accurate safety monitoring and early warning of key segments of coal mines, the development, structure and characteristics of "Internet of Things" (IOT) were discussed, which indicated that EPC Global and Ubiquitous ID (UID) systems are the most prevalent two models and Both contain “acquisition, transmission, processing and feedback of information”. After that, the physical model of safety expert system (SES) was established based on IOT, and the information acquisition segment was also introduced, which functioned as the core in the whole system. SES was thus utilized in coal mines which include different monitoring and control systems such as underground personnel monitoring system and automatic control system of main fan, and also an application example was discussed. The results show that the SES will be of great importance in safety monitoring and alerting of coal mines and worth promotion.

Abstract: To simulate arbitrary three dimensional models, this technology of triangular polyhedron 3D human-computer interaction modeling was proposed. Achieving the technology has following three steps. Firstly, the coordinates of 3D nodes were projected onto the plane by the method of 3D geometric transformation. Then, this information which was made up of triangles and sides and nodes was picked up by 3D picking methods. Finally, the technique of rubber membrane was used to modify the nodes of triangles, and the 3D modification was achieved by means of anti-transformation. Moreover, the method of global and local mesh encryption was also designed to modify 3D topology structure, which was aimed at better simulate complex 3D models. This technology combined geophysical forwarding compute and formed the method of data-interaction simulation, which provided a means of visualization for geophysical data interpretation.

Abstract: This paper aims at the solution to problems of large amounts of data storage, low efficiency calculate and poor user experience which actually exists in GIS application on mobile devices. In order to solve these issues we use GIS technologies including spatial data organization, map browser, and spatial index. We focused on the research of how to effectively utilize system resources and rational and efficient out organize the spatial data. What’s more, we improved the R-tree indexing algorithm to establish a rapid spatial index structure and used hierarchical classification techniques to optimize the efficiency of the real-time visualization of spatial data for mobile devices.

Abstract: The scenario analysis method is used widespread in environmental management fields. Massive scenarios used in the applications lead to huge computing workloads and time-consuming. A parallel computing algorithm based on the Message Passing Interface (MPI) standard was proposed to enhance the computing performance of scenario generating and calculating. By taking a river restoration planning problem as a case study, the proposed algorithm was applied in a decision support system and tested on a multi-core workstation. Experimental results show that when performed on a quad-core workstation, the algorithm reduced the execution time to a quarter of the former, with a stable speedup factor of 3.8 at different amounts of scenarios. It is indicated that the proposed algorithm is practical in environmental decision-making procedure, with special reference to the general scenario analysis method and other similar applications in the fields of energy and environment.

Abstract: In DSCM,mean of a seriously polluted target image’s subdomain usually has a significant random fluctuation, this reduces the accuracy of subpixel registration. This paper proposed a algorithm to inhibit the fluctuation by replacing the mean of target subdomain with the mean of a superset domain. Experimental data shows that in some places this process can significantly improve the accuracy of correlation measure function’s interpolation.
