    Knee osteotomy is a kind of orthopedic surgery to realign the lower limb by opening or cutting a bone wedge from the leg. It is a better alternative than other types of knee-replacement surgeries, especially for young people. However, knee osteotomy requires understanding the imbalance of stresses at the knee joint, analyzing an abnormal gait cycle, and cutting the bone wedge precisely. Therefore,... View full abstract»

    A colleague of the authors recently asked for a way to sample from a Poisson distribution to simulate the way metallic flakes cluster in paint. The flakes aren't distributed uniformly at random throughout the paint binder but form clusters around center points. The number of flakes around a center is distributed like the Poisson distribution. The article presents three ways to sample from the Pois... View full abstract»

    The authors present a geographic clustering technique which unambiguously locates, characterizes, and visualizes ecoregions and their borders. When coded with similarity colors, it can produce planar map views with sharpness contours that are visually rich in ecological information and represent integrated visualizations of complex and massive environmental data sets View full abstract»

    The Web has become a repository for a wide range of easily accessed information-from lecture notes to articles to recipes-all on hand for a large, varied audience. However, the ease of publishing (or posting) your information should match the ease of retrieval (download times notwithstanding). The author discusses software that converts documents created with Tex or LaTex into HTML files with mini... View full abstract»

    The authors present a visualization methodology which provides users with a way to alter perspectives and interpret visualization so that they can quickly identify trends, outliers, and possible clusters while tuning for a particular context. The technology developed for text mining is called Trust, or Text Representation Using Subspace Transformation. Trust provides an analysis environment that c... View full abstract»

  • How templates enable high-performance scientific computing in C++

    Publication Year: 1999, Page(s):66 - 72
    Cited by:  Papers (5)

    The C++ programming language has a powerful template facility that enables the development of flexible software without incurring a large abstraction penalty. Templates let programmers tell the compiler how to create classes and functions parametrized in terms of other types and constants. Programmers often use templates to implement type-safe generic containers that hold elements of a particular ... View full abstract»

    The authors' cosmological applications illustrate problems and solutions in storing, handling, visualizing, virtually navigating, and remote serving data produced by large scale adaptive mesh refinement simulations. The authors describe their cosmological AMR algorithm and how they applied it to star, galaxy, and galaxy cluster formation. Basically, the algorithm allows them to place very high res...

  • Hysteresis, avalanches, and noise

    Publication Year: 1999, Page(s):73 - 81

    In our studies of hysteresis and avalanches in the zero-temperature random-field Ising model, a simple model of magnetism, we often have had to do very large simulations. Previous simulations were usually limited to relatively small systems (up to 9002 and 1283), although there have been exceptions. In our simulations, we have found that larger systems (up to a billion spins)... View full abstract»

    Sound can help us explore and analyze complex data sets in scientific computing. The authors describe a digital instrument for additive sound synthesis (Diass) and a program to visualize sounds in a virtual reality environment (M4Cave). Both are part of a comprehensive music composition environment that includes additional software for computer-assisted composition and automatic music notation View full abstract»
