Mining is a complicated operation. There are many fields involved in mining ranging from exploration, engineering operations to environmental aspects. With the advancement of information technologies and mining industry operating techniques, the success of a mining operation is largely dependent on a group's ability to collect, manage, integrate, utilize available data sets and information, and draw the right conclusions. With the establishment of the world's first mine site virtual reality (VR) studio at Goldcorp's Red Lake Mine, the comprehensive data integration and immersive 3D datavisualization have been completed at the mine. The advantages of this type of data processing have been well demonstrated and the initial benefits are significant. This paper presents the mine data integration and comprehensive datavisualization at the Red Lake Mine by using a powerful, state-of-the-art technology - virtual reality. It reveals that the VR studio is not only a tool for visualizing mine information to help geologists/engineers view and understand mine engineering data, but it is also a powerful tool for mine data integration, modeling and analysis of disparate but available information. These allow professionals from different departments or disciplines to discuss, coordinate and optimize their plans and designs. VR allows mine operations to instantly see the financial impact of their decisions on mine safety, environment, direction of exploration drillholes, ore grade and excavation rates, mine plans, ground control methods, stress and seismicity, physical placement of stopes, ramps and other structures, as well as infrastructure, and engineering and human resources scheduling. The strategies for data integration and the datavisualization VR operating framework are discussed in this paper. Examples are also given to show the power resulting from data integration and the power of VR on engineering applications.

Interactive data Language (IDL) is an array-oriented dataanalysis and visualization application, which is widely used in research, commerce, and education. It is meaningful to make user IDL applications collaborative between computers over networks, using a common message broker as the underlying communication system. In order to achieve the global collaboration, we have brought together in the research a Grid-based Collaboration paradigm, a Shared Event model, different implementing structures, methodologies and technologies. We have succeeded in our prototype codes, and we are currently working on a real life IDL application package to make it collaborative. At the same time, we are trying to find better structures and methods for the collaboration in general user IDL applications.

Extension data mining is a new method that is based on the extension analysis method of Extenics. Extenics is a new disciplinary and a new branch of arfiticial intelligence. data mining techniques have their origins in methods from statistics, pattern recognition, databases, artificial intelligence, high performance and parallel computing and visualization. This paper presents how to deal with multiple data formats and unify data representation based on extenics. Keyword: matter-element, databases, extension data mining, association rules.

A visualization and steering application, GAVis, has been developed to aid in understanding the behavior of and guiding the convergence of genetic algorithms running in parallel over long time periods. When classification techniques such as Support Vector Machines (SVMs) paired with complete leave-one-out validation are used as a fitness function for identification of markers inomic data, the time to complete one generation can exceed an hour on modern high-performance computing clusters. Separate solution populations on "islands" can help maintain a more diverse solution space and conveniently map to compute nodes on a cluster. Adjustments can be made at runtime to speed the convergence of genetic algorithms by stimulating lagging island populations with migrations of high-performing individuals or by selectively increasing mutation rates.

Knowledge base system is one of the most future branches for artificial intelligence facing with practical application. But the reasoning process of system is invisible, not visual and users cannot intervene the reasoning process, therefore for users the system is only a black box. This condition causes many users to take a suspicious attitude to the conclusions analyzing and drawing from the system, that means even though the system has the explanation function, but it is still not far enough. If we adopt graph or image technique to display this reasoning procedure interactively and dynamically which can make this procedure be visual, users can intervene the reasoning procedure which can greatly reduce users' gain giving, and at the same time it can provide a given method for integrity check to knowledge of the knowledge base. Therefore, we can say that reasoning visualization of knowledge base system has a further meaning than general visualization. In this paper the visual problem of reasoning process for knowledge base system on the basis of the formalized analysis for ICON system, Icon operation, syntax and semanteme of the statement is presented, a reasoning model of knowledge base system that has a visual characteristics is established, the model is used to do an integrity check in practical expert system and knowledge base, better effect is got.

Community health research is practiced with disparate independently used tools that by themselves do not allow for the type of comprehensive and thorough analysis needed for effective public health evaluation. The Spatial OLAP visualization and analysis Tool (SOVAT) is a new type of research application for community health assessments. SOVAT integrates into one system many of the necessary characteristics needed to make comprehensive community health decisions. By combining On-Line Analytical Processing (OLAP) with Geospatial Information System (GIS) capabilities, our system can handle large amounts of data, perform geospatial and statistical calculations, and then display this information in both a numerical and spatial view within the same interface. It is anticipated that this unique system will provide researchers with the ability to perform more comprehensive assessments while enabling for more informed public health decisions.

Sort-last parallel rendering is an efficient technique to visualize huge datasets on COTS clusters. The dataset is subdivided and distributed across the cluster nodes. For every frame, each node renders a full resolution image of its data using its local GPU, and the images are composited together using a parallel image compositing algorithm. In this paper, we present a performance evaluation of standard sort-last parallel rendering methods and of the different improvements proposed in the literature. This evaluation is based on a detailed analysis of the different hardware and software components. We present a new implementation of sort-last rendering that fully overlaps CPU(s), GPU and network usage all along the algorithm. We present experiments on a 3 years old 32-node PC cluster and on a 1.5 years old 5-node PC cluster, both with Gigabit interconnect, showing volume rendering at respectively 13 and 31 frames per second and polygon rendering at respectively 8 and 17 frames per second on a 1024 x 768 render area, and we show that our implementation outperforms or equals many other implementations and specialized visualization clusters.
