    A group at the Swiss Federal Institute of Technology are studying nature's ability to create living systems that can produce energy, process information, self-replicate, self-repair, function with defects, adapt to their surroundings and improve the species over time through evolution. The group is looking at these natural processes in order to translate their underlying principles into the langua... View full abstract»

    Determining a material's macroscopic properties given its microscopic structure is of fundamental importance to materials science. The authors describe two public-domain programs that jointly predict macroscopic behavior: OOF (Object-Oriented Finite elements) and ppm2oof (Portable Pixel Map to OOF format translator). The programs start from an image of the microstructure and end with results from ... View full abstract»

    Mathematicians require proofs, mathematical physicists are content to know that a result is exact, and physicists require only a numerical approximation adequate for their purposes. This caricature is becoming increasingly inaccurate as computers become capable of refining approximations to the extent that we can make exact conjectures. Once you have a conjecture that you believe is exact, providi... View full abstract»

    Will peer-to-peer computing be the next killer Internet application? Like most over-hyped concepts, P2P is loosely defined and covers a set of rather disparate ideas. Perhaps the only common theme is a client-oriented view of the world; you might think of P2P as “Power to the People”. The servers are subservient to the clients, which do most of the work. P2P has several important techn... View full abstract»

    The authors describe a relatively simple problem that all investors face: managing a portfolio of financial securities over time to optimize a particular objective function. They show how complex such a problem can become when real-world constraints are incorporated into its formulation. More specifically, the authors present the basic dynamic portfolio optimization problem and then consider three... View full abstract»

    There are many simulation tools designed for specific applications. Users need to plug in application-specific parameters or models; the simulation tool will carry out simulation, graphics rendering, and animation. The article provides an extensive list of simulation tools. Simulating physics behaviors in real time presents challenging problems for scientists and graphics researchers. Such behavio...

    The article focuses on the use of computers for analysing and simulating turbulent flow. Turbulence theory has a well-earned reputation for being difficult, but, paradoxically, it is so difficult that it is actually accessible. Precisely because it is difficult to make progress analytically, an increasingly important part of turbulence theory is computational. The peculiarities of real turbulence ... View full abstract»

    The authors present their 2nd February 2001 Department of Defense report, with minor edits, analyzing US government export control strategies for high-performance computing. Due to advances in clustering technology, export controls on high-performance computer systems are found to be no longer effective. The authors recommend a shift away from hardware controls to protections on critical defense a... View full abstract»

    In the area of field theory scientific computing, having a basic library that would let us introduce state-of-the-art software engineering concepts to our projects would save us all much time and effort. The article describes TETlib, an object oriented library, implemented in C++ to do just that. The authors introduce the library design and their programming philosophy View full abstract»

    Almost all interesting mathematical algorithmic questions relate to NP-hard questions. Such computation is prone to explode exponentially. The authors anticipate the greatest benefit will come from mathematical platforms that allow for computer-assisted insight generation, not from solutions of grand-challenge problems View full abstract»

    Scientists and engineers often use Poisson's probability distribution to characterize the statistics of rare events whose average number is small. Using it correctly is crucial if we are to validate claims of discovery of new phenomena, such as a new fundamental particle (few candidate collision events among millions), a remote galaxy (few photons in the telescope among the billions emitted), or b...

    Computational methods are part of the problem solving skills that professionals working in quantitative fields need. Advanced text-books provide the mathematical foundation for one specific approach, however, they miss the overview and examples that are generally necessary to choose the right method and implement a practical solution. Internet technology can be of great value in this context. Thus... View full abstract»
