AST-0313031KrolikThe investigators intend to create the next generation of scientific visualization systems, with particular application to the results of magneto-hydrodynamic simulations of black hole accretion. Complex simulations of this sort require an application which is more flexible and much more easily manipulated by users who are not computer specialists than any existing technique. The new system will emphasize speed and ease of use, and tying system development to a specific scientific problem will ensure that it is realistically designed and well tested. The PIs already have a prototype system, but it requires significant enhancement to become a working tool for scientific analysis, particularly in the areas of interactive data set combination, hierarchical visualization of vector fields, and graphics-hardware-compatible compression and decompression.Using this interactive system will deepen our understanding of accretion, by showing characteristic timescales and thus which process is dominating the dynamics, by defining the topology of the magnetic field lines, and by enabling investigation of quasi-periodic oscillations. It will also explore the generation of stresses in accretion flows, how energy release is controlled, and where energy is dissipated.The research will provide a solid basis for user-guided visualization in many other scientific fields, through public availability of the developed system. It will train graduate students in both sophisticated data analysis and computer systems development, and it will expose undergraduates to sophisticated problems.

AST-0313031KrolikThe研究者打算创建下一代的科学可视化系统，并特别适用于黑洞积聚的磁烟动动力学模拟的结果。 此类复杂的模拟需要一个更灵活的应用程序，而不是计算机专家的用户比任何现有技术更容易操纵。 新系统将强调速度和易用性，将系统开发与特定的科学问题联系起来将确保其经过现实设计和经过良好的测试。 PI已经具有原型系统，但是它需要显着增强才能成为科学分析的工作工具，尤其是在交互式数据集组合，对矢量领域的层次可视化以及图形 - 硬件兼容的压缩和减压的领域，通过乘坐特征性的乘坐范围，可以使我们对磁场的理解加深我们对磁性的理解，从而使该过程的磁性更深入，并且可以使该互动系统深入启动。实现了准周期振荡的研究。 它还将探索积聚流中的应力产生，能源释放的控制方式以及能量消散的位置。该研究将通过公开的开发系统的公众可用性为许多其他科学领域的用户指导可视化提供良好的基础。 它将培训研究生进行复杂的数据分析和计算机系统开发，并将使本科生面临复杂的问题。
