    If you write Web pages, especially instructional ones, you will probably at some point want to embed a movie in a page, perhaps to demonstrate or show an in-class experiment in near real time. This journey from hypertext to hypermedia can be quite bumpy; there are many problems to deal with. The article discusses how to hide the bumps from both yourself and your reader.

    The goal of virtual reality is to fully or partially immerse a human in a visually coupled environment. By tracking the position and orientation of the user with sensors designed for this purpose and by coupling these measurements with a high-performance computer graphics system, we can generate a computer-synthesized view of a virtual environment that responds to the user's movements. Thus, the u... View full abstract»

    For almost 50 years, researchers have attempted to understand the geodynamo, a mechanism that maintains the Earth's geomagnetic field. The authors discuss their results using the Glatzmaier-Roberts model to create numerical simulations of the geodynamo (G.A. Glatzmaier and P.H. Roberts, 1995) View full abstract»

    High-speed and large-volume computational capabilities have affected many branches of scientific research. Interferometric synthetic aperture radar (InSAR) and its spatially dense, accurate deformation measurements have advanced studies of the Earth's crust. The most important contributions are related to seismic and volcanic processes and the mapping of glacier and ice-sheet motions in the enviro... View full abstract»

  • Cellular-automata models applied to natural hazards

    Publication Year: 2000, Page(s):42 - 51
    Cited by:  Papers (30)

    The concept of self-organized criticality evolved from studies of three simple cellular automata models: the forest-fire, slider-block, and sandpile models. Each model is associated with natural hazards which have frequency-size statistics that are well approximated by power law distributions. These distributions have important implications for probabilistic hazard assessments View full abstract»

    Seismologists, and more recently computational and condensed-matter physicists, have made extensive use of computer modeling to investigate the physics of earthquakes. The authors describe a simple cellular automaton model that explores the possible relationship between Gutenberg-Richter scaling law and critical phenomena. The presence of scale invariance coupled with the ubiquity of this law in d... View full abstract»

    Current computing practice requires great effort to produce an application with a reliable, distributed, heterogeneous, adaptive, dynamic, real time, parallel or secure execution. One exception is a bag-of-tasks application. Examples of such applications include the simulation of independent trials, the processing of independent media frames, and the evaluation of independent candidate solutions. ... View full abstract»

    Discusses a particular application of computational physics: the calculation of thermodynamic properties by computer simulation methods. More specifically, we focus on one of the most difficult tasks in this context: the estimation of free energies in problems such as the study of phase transformations in solids and liquids, the influence of lattice defects on the mechanical properties of technolo...

  • Plate tectonics and convection in the Earth's mantle: toward a numerical simulation

    Publication Year: 2000, Page(s):22 - 33
    Cited by:  Papers (7)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2140 KB)

    Numerical models of mantle convection are starting to reproduce many of the essential features of continental drift and plate tectonics. The authors show how such methods can integrate a wide variety of geophysical and geological observations. The goal is to combine the Stokes and energy equations with a realistic rheology, thereby letting us understand the complex dynamic coupling that occurs in ... View full abstract»

    Wavelet shrinkage denoising provides a novel method of reducing noise in signals. The author demonstrates 1D and 2D examples, tests the performance of various ideal and practical Fourier- and wavelet-based denoising procedures, and makes recommendations for practitioners. It is is concluded that it is unlikely that one particular wavelet shrinkage denoising procedure will be suitable, no less opti... View full abstract»

    The rapid growth of Internet based businesses that is occurring while mature business cannibalize each other through mergers suggests the power of the individual with a good idea. The question is how to transfer this knowledge to business. Universities, which are the sources of much new knowledge, can aid in this process. To demythify entrepreneurships, universities are rolling out programs to hel... View full abstract»
