    The first year of my tenure as Editor in Chief has concluded, so I think it's appropriate to reflect on what has transpired over the past six issues in light of what I originally envisioned. Several points from my first EIC message synopsize what I had in mind. View full abstract»

  • Hurricane forecasting: reducing future losses

    Hurricanes are born of the sea, and they die over land. It's at that brief moment when they cross between the two that they do the most damage. The worst part of a hurricane's fury is over in hours, and its remnants subside in days. But a hurricane's other impacts - its human losses and economic costs - begin long before it ever reaches land, and linger long after it's gone. Predicting the number ... View full abstract»

    As with the examples provided in the September/October 2005 issue, these articles describe cutting-edge research in scientific grid computing. Although it's also possible to use grid computing to address small-scale scientific computing needs, our aim in assembling both these issues has been to focus on large-scale work--indeed, work that can’t be done in any other way, for want of computatio...

    Within a decade after John von Neumann and colleagues conducted the first experimental weather forecast on the ENIAC computer in the late 1940s, numerical models of the atmosphere become the foundation of modern-day weather forecasting and one of the driving application areas in computer science. This article describes research that is enabling a major shift toward dynamically adaptive responses t... View full abstract»

    This article describes the configuration, monitoring, management, and use of compute clusters in an environment in which users access resources via grid middleware tools rather than direct logins. The work described here shows that setting up and managing clusters within grid environments is feasible without large investments in support or user training. View full abstract»

    Looks at the UltraLight project which treats the network interconnecting globally distributed data sets as a dynamic, configurable, and closely monitored resource to construct a next-generation system that can meet the high-energy physics community's data-processing, distribution, access, and analysis needs.

  • An efficient numerical spectral method for solving the Schrodinger equation

    Spectral expansions of a smooth function converge rapidly and are suited for accurate solutions of differential or integral equations. Based on such expansions, the authors have developed a numerical algorithm for solving the Schrodinger equation. View full abstract»

  • Binary and multivariate stochastic models of consensus formation

    We consider stochastic dynamic models studied via computer simulation. We review some basic results for the voter model which is probably the simplest model of collective behavior. Specifically, we focus on the dynamical effect of who interacts with whom - that is, the consequences of different interaction networks. We also consider R. Axelrod's (1997) model for the dissemination of culture. View full abstract»

  • Fast solvers and Sylvester equations: both sides now

    Cited by:  Papers (2)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (472 KB) | HTML iconHTML

    We're using the structure of a problem with n2 unknowns to reduce the amount of computation from O(n6) (using the Cholesky decomposition) to O(n4) (exploiting sparsity) and then to O(n3) (using the Sylvester structure), a substantial savings when n is large. But knowing just a bit more about the problem's structure allows further reduction, down to O(n... View full abstract»

    Just being able to program in Python is powerful, but the real payoff is in its extension to other compiled assets. The article introduces several Python variants and examines a powerful new addition to Python itself. However, the products described also have some limitations. Until we standardize windowing systems, compiler controls, languages, and build tools even further, portability problems w... View full abstract»

  • The fast Fourier transform for experimentalists, part IV: autoregressive spectral analysis

    We consider two additional kinds of spectrum estimates: autoregressive (AR) estimates and the maximum entropy (ME) method. In the first approach, we assume that an AR process generates the time series, which means we can compute the PSD of the time series from estimates of the AR parameters. The second approach is a special case of the first, but it uses a different method for estimating the AR pa... View full abstract»

    According to the 16 August 2005 Wall Street Journal, federal bean-counters are increasingly forcing universities to pay back mishandled research money. Interestingly, the paper cites a study by HealthPartners Research Foundation and the University of Minnesota that found more than 50 percent of established grant-getting scientists used grant money designated for one project on another project, oft...
