    A novel framework leverages physical properties for mining in data-scarce domains. It interleaves bottom-up data mining with top-down data collection, leading to effective and explainable sampling strategies. This article describes focused sampling strategies for mining scientific data. Our approach is based on the spatial aggregation language, which supports construction of data interpretation an...

    High-resolution rainfall forecasting has important benefits, such as enabling flood prediction, yet little progress has been made toward developing an effective strategy. The hybrid approach presented here combines weather physics, statistics, and artificial neural networks. The strategy is able to draw on all available information, account for and use aspects of the domain physics that are better... View full abstract»

    Over the last decade or so, there has been much discussion of and progress in computational science. The US High Performance Computing and Communications Initiative and the National Science Foundation (NSF) grand challenge programs largely focused on this trend. Now the NSF has a new cyber infrastructure report continuing the same emphasis on distributed systems. The author looks at the impact of ... View full abstract»

    Most of the work in scientific computing today is done in parallel algorithms, often via message-passing architectures such as the message-passing interface (MPI). A newly emerging language called Ruby, which maintains a strict adherence to object oriented principles and a clean, intuitive syntax. The author created MPI Ruby, a complete binding of MPI to Ruby. In this article, he introduces Ruby a... View full abstract»

    Astronomy data sets have led to interesting problems in mining scientific data. These problems will likely become more challenging as the astronomy community brings several surveys online as part of the National Virtual Observatory, giving rise to the possibility of mining data across many different surveys. In this article, we discuss the work we performed while using the catalog from the FIRST (... View full abstract»

    While the potential for a global neuroscience network is vast, the technological and cultural obstacles to establishing the network are also daunting. As the science of brain mapping developed, it was hamstrung by insufficient processing power and data transmission capabilities to allow widespread sharing of brain imagery and related data. The Human Brain Project, initiated in 1993 by the National... View full abstract»

    One effective way of exploring large scientific data sets is a process called feature mining. The two approaches described here locate specific features through algorithms that are geared to those features underlying physics. Our intent with both approaches is to exploit the physics of the problem at hand to develop highly discriminating, application-dependent feature detection algorithms and then... View full abstract»

    We have developed a visualization tool for monitoring and displaying resin flow during the fabrication of composite laminates. The tool integrates network-based data acquisition, fast finite element based reconstruction (smoothing) and contouring algorithms, and scientific visualization. It helps users better understand the design process and will be at the center of our intelligent design and con... View full abstract»

    At Mercer University, we have developed an online interactive chaotic pendulum. This pendulum is unique in that it is not a computer simulation but an actual device that can be remotely controlled through the Internet. Our objective is threefold. We are attempting to provide an educational resource for chaos, demonstrate a new technology, and experiment with a new method of laboratory education. A... View full abstract»

    Can computational grids make as great an impact in the 21st century as electrical grids did in the 20th? A comparison of the two technologies could provide clues about how to make computational grids pervasive, dependable, and convenient. In this article, we describe how computational grids developed, their layered structure, and their emerging operational model, which we envisage as providing sea... View full abstract»

    For Part II see ibid. vol.3 no.6 (2001). In previous parts we used linear least squares to fit polynomials of various degree to the annual global temperature anomalies for 1856 to 1999. Polynomials are much beloved by mathematicians but are of limited value for modeling measured data. Natural processes often display linear trends, and occasionally a constant acceleration process exhibits quadratic... View full abstract»

    A data web can simplify the processes of cleaning, transforming, and exploring data in a data mining application. DataSpace is one such mechanism that lets scientists view, retrieve, and apply simple transformations to remote and distributed data. DataSpace is an example of a data web, that is, a web-based infrastructure for working with data View full abstract»
