    To solve critical biosphere-level problems such as global warming, decreased biodiversity, and natural resource depletion, scientists must integrate data from many researchers. This, in turn, requires better data infrastructure and informatics tools than are currently available. The Canopy Database Project brings together computer scientists and ecologists to develop informatics tools for forest c... View full abstract»

    Many graphics and visualization applications require fast rendering and animation of finely detailed objects constructed of what I call atomic primitives. A primitive is a basic graphics shape - such as a line or triangle - that is scan-converted into a frame buffer. An atomic primitive is a very small primitive. I introduce new approaches in graphics pipeline hardware design that can speed up the... View full abstract»

    Inverse problems are among the most challenging computations in science and engineering because they involve determining the parameters of a system that is only observed indirectly. For example, we might have a spectrum and want to determine the species that produced it as well as their relative proportions, or we may have sonar measurements of a containment tank and want to know whether it has an...

    The author considers recursion: functions, subroutines, and even whole computer languages defined in terms of themselves. Recursion is a direct and elegant way to translate certain mathematical relations into programs, and it's a great technique for discovering efficient algorithms. Given its utility, it is seldom used. Correctly used, recursion is so valuable you should use it whenever it makes p... View full abstract»

    Database collections were quite minimal in surface spectroscopies in 1990, when the American Vacuum Society (now named AVS, The Science and Technology Society) began to develop a spectral database, called Surface Science Spectra (or SSS); http://sss.avs.org. (Surface spectroscopies include X-ray photoelectron spectroscopy, Auger electron spectroscopy, ultraviolet photoelectron spectroscopy, second... View full abstract»

  • A new look at expression templates for matrix computation

    We reinterpret the expression templates for matrix computation put forward by other authors in light of functional programming ideas. Existing expression template libraries frequently focus on componentwise operations such as addition at the expense of matrix multiplication. The ideas presented are implemented in a C++ library called LLANO (Lazy Linear Algebraic Numerical Objects). View full abstract»

    Storing and organizing scientific and engineering information is a natural application for databases. But database designs and systems have conventionally been driven by the business-application market, especially by large businesses. The authors introduce a hybrid open source/proprietary approach to creating a dynamic Web site for modest laboratory or academic use. Although they cannot claim our ... View full abstract»

    We consider a project that's ongoing at our Pervasive Technology Lab at Indiana University. The HPJava (high-performance Java) project aims to support scientific and parallel computing in a modern, object-oriented, Internet-friendly environment - the Java platform. HPJava leverages popular high-performance Fortran (HPF) language and library features such as "scientific" multidimensional array synt... View full abstract»

  • Modeling a magnetic Moon

    Using an innovative computer model, Dave Stegman and his coauthors might have solved a decades-old mystery about the Moon's geology. A giant plume of hot rock, they say, might have burst out from the lunar core four billion years ago, kicking off a series of events that endowed the moon with a temporary magnetic field. Stegman's model is prompting scientists to re-examine studies of magnetic lunar... View full abstract»

    Describes the Scientific Annotation Middleware, a set of components and services that support the creation and use of annotation metadata describing data objects and the semantic relationships among them. It captures aspects of data processing history and the research process and federates the results into a coherent human- and machine-interpretable research record. View full abstract»

    Electrostatic problems are those that deal with the effects of electric charges at rest. For modern electron and microelectromechanical systems (MEMS), an accurate electrostatic analysis is both essential and indispensable. We know that if we use the conventional boundary element method for electrostatic problems that have singularity due to degenerate boundaries, the coincidence of the boundaries...
