Abstract: According to the special requirement of protective relaying setting in coal mine power system, the research and development of a visualized protective relaying setting software is described in this paper. Firstly, software architectural and its functional module is defined to meet special needs, then a novel setting method based on ‘triggered by setting condition’ and action simulation method based on setting value are proposed. Object-oriented and visualized programming means ensure its users can easily and directly carry out the setting calculation of protective relaying and simulate the protective action. The application and the achievements of good effects at last ensure its rationality.

Abstract: With the advent of the era of big data, data visualization display faces great challenges. Big data, especially in industries such as telecommunications, finance, almost to the point of "data is the business itself". At this time, in order to let more people understand, use and analyze the data better, we proposed the method to display the big data in the field of finance and the notion of the Zoom financial data visualization (ZFDV). By providing a consistent set of the preliminary design of ZFDV and the interaction of ZFDV techniques, ZFDV makes it possible for users to browse through very large data sets. These techniques use the structure of the displayed data to guide the human-interaction and provide a way to improve interactive navigation in the financial.

Abstract: Real estates are the material basis of the survival and development of a city, and are important parts of urban development. We use 3ds Max as a tool to create 3D models of buildings and Supermap Deskpro.NET as a platform to make an effective combination of 3d models, real estate graphic data and real estate attribute data. Three-dimensional display of surveying and mapping information and three-dimensional visualization management of house property information are realized.

Abstract: As an important living place for human beings, city is regarded as a main place for the birth, spread and development of human civilization. This paper, based on the principle of system development and combining with the need of building “Digital City”, makes an overall design of the “Digital City” 3D visualization system. Firstly, a 3D ground objects model, i.e. .x files, is made through inputting the ground objects of the experimental area into 3DSMAX, then, the .x files are converted to .xpc files in order to achieve a better displaying effect in producing a 3D landscape. Secondly, the author makes corresponding pre-processing to the aerial photos, satellite images, topographic data, digital elevation models and a variety of vector geographic data, and then superimposes and loads these data into Terra Builder module of Skyline software, which generates 3D topography landscape, that is, .MPT files and forms the terrain database required in Terra Explorer Pro software. Next, a 3D landscape is preliminarily established by inputting the 3D terrain model and the 3D ground objects model, i.e. .MPT files and .xpl files, in Terra Explorer Pro, and by editing a real and accurate 3D geographic model and a real Digital City 3D landscape model, that is, FLY files, are respectively formed. Finally, on the basis of the 3D landscape model, the system is developed by using Visual Basic + TerraDeveloper and the basic operation of 3D, spatial analysis, visible analysis and other basic functions are preliminarily achieved

Abstract: With the development of calculation ability and data processing ability of computer,so process complex data has become possible,with computer graphics methods, in a easily observe graphic way to represent data requirements has became popular day by day. The article describes some fields which attract users' attention,such as scientific processing, landscape simulation,visualization research technique in medical diagnosis.

Abstract: With the rise of the network,everyday the video websites update plenty of video datas.Faced with a lot of video datas,if you only rely on the human to analyze the video datas in order to dig out the information hidden in the video room,it will take a lot of time and is difficult to achieve the desired result. This paper develops a data mining and visualization system,which visualized shows the relationship between the video datas through a network graph of nodes.Based on visualized showing the relationship between the video datas,the system provides the tool to analyze the video datas and dig out the information hidden in the video room.

Abstract: A study was carried out on the influence of different back pressures on internal flow of diesel injector nozzles. For this study, a flow visualization experimental system equipped with a pressurized chamber was setup. Experimental results show that, with the injection pressure remain constant and increase back pressure leading to the cavitation area diminished gradually and even disappeared. With a same pressure difference, higher back pressure test condition promoted the outlet mean velocity and inhibited the occurrence of cavitation inception, which demanded a larger pressure difference to make it happen. Moreover, it also resulted in a relatively large flow losses to the single phase flow compared to the cavitating flow.

Abstract: Build a mathematical model by using the voltage loop of UCC28019 to get open loop transfer function. And use MATLAB to obtain variable range of voltage loop parameter when system is stable, in the mean time, use system time domain performance as objective function to optimize the parameter, based on system stability. The user can get better parameters on the three-dimensional image clearly and directly, for there is no complex formula and theoretical derivation in process of optimizing. Hardware circuit experiments verify the effectiveness of the proposed method.

Abstract: With the rapid development of the power industry, there has been more and more large thermal power unit which is more than or equal to 600MW , steam turbine equipment gradually tend to be high parameter, large capacity, complicated, the overhaul maintenance to steam turbine is the main content of the power plant production activities, it directly affects the reliability of the coal-fired power plant production safety. Aimed at the complexity of thermal steam turbine overhaul, by the use of advanced interactive devices on the visual, do an auditory perception of the virtual environment for something, which is helpful to improve practical operation skills. This paper examines the necessity and superiority of this system applied in education and training. Taking 3-D dynamic simulation system of building as an example, this paper discussed how to utilize the SolidWorks2012 and VRP - SDK to build a virtual training system, realized the combination with virtual reality and education training ,also greatly promoted science and technology progress，equipment of the steam turbine overhaul industry.

Abstract: Analyzing similarities and differences between biomolecular networks comparison through website intuitively could be a convenient and effective way for researchers. Although several network comparison visualization tools have been developed, none of them can be integrated into websites. In this paper, a web-based tool kit named dynamically adaptive Visualization of Biomolecular Network Comparison (Bio-NCV) is designed and developed. The proposed tool is based on Cytyoscape.js – a popular open-source library for analyzing and visualizing networks. Bio-NCV integrates arjor.js which including the Barnes-Hut algorithm and the Traer Physics library for processing in order to express the dynamically adaptive initialization. In addition, in order to maintain consistency, the counterparts in other networks will change while the nodes and edges in one of the compared networks change. Furthermore, Bio-NCV can deal with both directed and undirected graphs.
