Aiming at the problems of conventional underground engineering feedback analysis methods, such as being limited in local optimization and computing data being very complex, the paper introduced difference evolution arithmetic and visualization toolkit, and combined three dimensional numerical simulation and orthogonal design, developing the intelligent feedback analysis system based on Visual c#. The system theory, software frame and develop method are introduced, the system could be used to calculate and evaluate the state of tunnel surrounding rock based on in-situ monitoring data. The system is applied in an actual tunnel engineering, the analysis results are satisfied, which states it is feasible and has good potential application.

data mining is a fast-growing field of study in Computer Science and Information Systems. Many schools have developed data mining course for undergraduate students. The course content has been well defined and streamlined because of the availability of outstanding data mining textbooks. However, the focus on theoretical contents of data mining makes it hard for undergraduate students to digest, and thus, compromises the overall learning outcome. To create an effective and dynamic learning environment, we introduce a practice-oriented approach. This paper describes how we integrate the hands-on component into the course work to enhance the learning of the core data mining topics including data preprocessing, association mining, classification, cluster analysis, text mining, and visualization. The open-source data mining tool, RapidMiner, is introduced to assist students to explore and digest various data mining processes and algorithms. Overall, the hands-on experience provides students a better insight into data mining functions.

VisPartDEM is a novel grid visualization tool for large particle systems simulated by the discrete element method. Architecture of VisPartDEM is designed for grid infrastructure build by gLite middleware. XML interface for remote data is developed to provide grid users with the interactive dataset selection by using GUI. Parallel visualization engine of VisPartDEM runs on working nodes of a computing element while the compressed video stream is efficiently transferred through the network and displayed on the client by Remote Viewer, which offers high interactivity level. Performance analysis of VisPartDEM is made on BalticGrid testbed based on multi-core architecture.

Traditional bone atlas modelling is carried out using linear methods such as PCA. Such linear models use a mean shape and principal modes to represent the atlas. A new shape, which is a high dimensional data vector, is then described using this mean and a weighted combination of the principal modes. The use of alternate methods for modelling statistical atlases have not been explored very much. Recently, there has been a lot of new work in the areas of multilinear modelling and nonlinear modelling. They present new ways of modelling high dimensional data. In this work, we compare and contrast several linear, multilinear and nonlinear methods for bone atlas modelling.

1- or 2-directional MRI blood flow mapping sequences are an integral part of standard MR protocols for diagnosis and therapy control in heart diseases. Recent progress in rapid MRI has made it possible to acquire volumetric, 3-directional cine images in reasonable scan time. In addition to flow and velocity measurements relative to arbitrarily oriented image planes, the analysis of 3-dimensional trajectories enables the visualization of flow patterns, local features of flow trajectories or possible paths into specific regions. The anatomical and functional information allows for advanced hemodynamic analysis in different application areas like stroke risk assessment, congenital and acquired heart disease, aneurysms or abdominal collaterals and cranial blood flow. The complexity of the 4D MRI flow datasets and the flow related image analysis tasks makes the development of fast comprehensive data exploration software for advanced flow analysis a challenging task. Most existing tools address only individual aspects of the analysis pipeline such as pre-processing, quantification or visualization, or are difficult to use for clinicians. The goal of the presented work is to provide a software solution that supports the whole image analysis pipeline and enables data exploration with fast intuitive interaction and visualization methods. The implemented methods facilitate the segmentation and inspection of different vascular systems. Arbitrary 2- or 3-dimensional regions for quantitative analysis and particle tracing can be defined interactively. Synchronized views of animated 3D path lines, 2D velocity or flow overlays and flow curves offer a detailed insight into local hemodynamics. The application of the analysis pipeline is shown for 6 cases from clinical practice, illustrating the usefulness for different clinical questions. Initial user tests show that the software is intuitive to learn and even inexperienced users achieve good results within reasonable processing time
