    The title of this article refers to Rudolph Flesch's famous 1955 book, "Why Johnny Can't Read", which called attention to a nationwide decline in reading ability. Here, the author wants to talk about another situation in which an important ability is lacking: the ability to create significant, portable scientific software. The author discusses some of the reasons this problem exists and suggests s... View full abstract»

    This paper describes new audio capabilities that are not just technologies; it also reflects an understanding of how to use audio to support information tasks. The following assertions underlie these new capabilities: meaningful non-speech sounds can function like words; sound design is a critical factor in the effective use of sound; sonification is an option for conveying information; sound can ...

    Many projects in engineering and science require data classification based on different heuristics. designers, for example, classify automobile engine performance as acceptable or unacceptable based on a combination of efficiency, emissions, noise levels, and other criteria. Researchers routinely classify documents as "relevant to the current project" or "irrelevant". Genome decoding divides chrom... View full abstract»

    MC-Sym is an intelligent computer system that builds 3D ribonucleic acid structures from low-resolution data by combining symbolic and numerical computations. Specifically, the symbolic step generates all-atom sketches of 3D structures that nonlinear optimization methods can refine in a second step. View full abstract»

    A commercial, object-oriented database engine with custom tools for data-mining the multiterabyte Sloan Digital Sky Survey archive did not meet its performance objectives. We describe the problems, technical issues, and process of migrating this large data set project, to relational database technology. View full abstract»

    For original paper see "Integrating Computing and Information on Grids", ibid., p. 94-96 (2003). We covered the important role that the Grid is expected to have in information systems, focusing primarily on sensor and database grids. we contrasted this with the major original Grid focus of metacomputing, or the Grid's linking together distributed computers. Whatever type of Grid you have, metadata... View full abstract»

  • Visualization in atomistic and spin simulations

    Certain basic demands from visualization code are common to all atomistic or spin systems; some are also relevant to more general visualization needs. Many commercial and homegrown visualization codes could meet these demands, but obviously the specific code used is less important than the fact that a visualization is made. The author describes in detail one specific public-domain code that meets ... View full abstract»

    Congestion in the USA's air transportation system is a major national problem - worse yet, it is likely to increase (perhaps to the point of crisis) in the next few years. This is a very complex problem, yet, with the aid of appropriate software tools, it is feasible to involve undergraduate students in sophisticated research projects that could help illuminate this complex system's workings.

    New methods of processing DNA microarray data use the self-organizing map, principal components analysis, and 3D data plotting to discover gene patterns, reduce gene data dimensions, and visualize the final results interactively in 3D space. The system described here integrates these new approaches in gene data processing, allowing further study and gene mystery decoding. View full abstract»

  • Dimension reduction and spatiotemporal regression: applications to neuroimaging

    One method for characterizing spatiotemporal variation in brain activity levels is based on the use of statistical dimension reduction. This reduction finds temporal components in data that best preserve the spatiotemporal regression structure. The method does this by suppressing more prominent waveforms that do not vary in a spatially predictable pattern. View full abstract»
