Abstract: This paper reports on an expert advisor for forex trading based on Back Propagation Neural Network (BPNN) in MetaTrader4 platform. A single hidden layer feedforward network was established for foreign exchange rate prediction. Trading rules based on the prediction results was designed and realized. Finally, we optimized the parameters according to the profitability performed on EUR/USD, GBP/USD currency pairs separately. The optimized results are able to achieve good results in the training series. In the test series, the strategies are consistently profitable for at least the first twenty days. It is concluded that the BPNN based model do have the ability to make profits from the experimental currency pairs for the period investigated.

Abstract: Ontology combined with the development of computer technology in all fields initiated the research of construction and application for so-called domain ontology. This article starts with the issues of current computer technology in the oil exploration and development domain, provides a construction method of oil exploration and development domain ontology based on a multi-level business process,and divides the oil exploration and development domain into multistage business activity levels,and takes hydrocarbon prospect characterization as example and discusses a construction method for corresponding micro-ontology.

Abstract: Retracted paper: Many steganographers would agree that, had it not been for vacuum tubes, the study of forward-error correction might never have occurred. After years of structured research into online algorithms, we prove the investigation of write-back caches. We describe an extensible tool for architecting replication, which we call Solve.

Abstract: According to the unceasing development of geotechnical survey technology and the demand of land resources survey management, Geographic Information System technology is proposed to establish spatial database to provide survey information for land resources surveyors and designers. At the same time, on the basis of geotechnique survey current status and integrated system, discuss the application analysis of Geographic Information System on geotechnique survey.

Abstract: The small or medium-sized airports are generally lack of airport surface movement detection equipment due to the insufficient financial budget in early and latter investigation of airports constructions or facilities. The paper studied airfield surveillance in the small or medium-sized airports by image processing technology and also discuss diverse surveillance sources in large airport and RWSL one of most key components in A-SMGCS. The analysis include: physical installation of video sensors, range of surveillance coverage, the flowchart of processing, the algorithm for detecting and tracking the moving objects which is suitable for environment of airfield in airport, the projection method between video image coordinate and airfield plan coordinate and the evaluation index of image processing technology.

Abstract: In allusion to the colored image matching characteristic in the system of robot view navigation, SSDA (the sequential similarity detection algorithm) is improved and adaptive genetic algorithm is brought in; meanwhile, level-divided search strategy connective with rough and exact matching. The improved algorithm can enhance the image matching speed with no matching accuracy reduced, so that real-time requirements of robot view navigation can be met and robot view navigation will be of preferable robustness.

Abstract: The Three-dimensional engineering geology data warehouse is constructed by Power Desinger16.1, with the theme as the rock and mass availability in urban underground space, and with the source data as the borehole data of engineering Investigation. Use the Model-driven Architecture method, reverse engineer the Access data base, extract existed data model, combine research theme to construct the Star data structure model. And check the SQL script in SQL Server2005, to ensure normal operation. 0 Forewords The traditional transaction-oriented designed engineering geology data base has the function to storage original data from work, to draw of geological section and to provide simple check and analysis, but without the decision support function in view of a subject. The purpose of construction a 3D engineering geological data warehouse is to build a decision support system in view of availability of rock and soil mass in urban underground space. Based on the data extraction, data integration, data cleaning and data transformation, the 3D engineering geological data warehouse could achieve the integrated management of massive geological data and to provide reliable data source for the rock and soil mass utilization system in urban underground space. The main feature of 3D engineering geological data base is subject-oriented, integrated, time-varying, relatively stable, and is magnanimous collection of engineering geological spatial data and attribute data. According to the design pattern of traditional data base, the construction of 3D engineering geological data warehouse can be divided into three stages: concept design model, logic design model and physical design model. But the 3D engineering geological data warehouse exist iterative in the construction process. Currently, there are many CASE tools to help developers quickly achieving the data base design, such as Rational Rose by Rational company, Erwin and Bpwin by CA company, Power Designer by Sybase company, Office Visio by Microsoft company, and Oracle Designer by Oracle company. The paper uses the Powerdesigner16.1 to achieve the logical data model (LDM) and physical data model (PDM).

Abstract: The system for well-logging data designed for data files unified management, can offer a function based on data query and download, also can offer instant replays for data curves. This system contains some functions following that format converting, uploading, query, download and preview for well-logging data curves. All system is designed by software Delphi GDI+.

Abstract: The paper introduces the development status of smart home platform based-on Android system and advantages of Smart home security system first.As to the families internal application environment,a low-cost,easy to expand,smart home security system for home applications based on the Android platform is designed through the analysis and research of smart home security system.It Shows the basic module structures of the software according to the design scheme,and each module performs the specific implementation.

Abstract: Data acquisition and record system plays an important role in signal processing. For the wideband signal acquisition and processing application, such as 3G/4G Base Stations, Wideband Microwave Backhaul, Military Communications, and RADAR, the need for high speed and smart software-defined radio (SDR) test platform is growing. In this paper, we implement a high compact form factor data acquisition and storage system used for the wideband signal application development. In order to implement high compact, low power and high speed real-time data storage, we use a PCIe-based switch architecture and leverage the Flash array as the storage part. The system supports RF sampling directly and offers a 16TB solid state storage module which could be read and write at the sustained speed of 12.8GB/s.
