    A computer has three logical systems. The central processing unit (CPU) that processes data according to instructions. The memory and storage system that stores instructions and data (it can be a volatile temporary memory or a permanent storage system like hard disks). Lastly, the input/output system that is responsible for communication between the computer and external entities. The memory and s... View full abstract»

  • Nanofabrication using Coulomb crystals

    Publication Year: 2000, Page(s):10 - 15

    We describe a selective area transfer of a Coulomb crystal. This is the first step towards a hybrid nanofabrication scheme employing both self-assembly and lithography. We have coined a term for this process; we call it "nanoxerography" since that is more or less how a Xerox photocopier machine works. Such techniques can ultimately lead to the marriage of self-assembly with nanolithography View full abstract»

  • A valuable tool: symbolic computation

    Publication Year: 2000, Page(s):34 - 35
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (92 KB)

    The use of symbolic computation is proposed here as an effective tool for studying electric circuits. Using well established methods to write electric circuit equations, a student can generate a set of equations involving only state variables. With the help of symbolic computation, these equations can be rewritten in a normal form. They then can be solved for any input-output pair. Furthermore, th... View full abstract»

    Discusses how bacteriorhodopsin is a revolutionary material in the battle to bring computing down to the molecular level. Amazing advances can be made by using this protein in three-dimensional optical memory. A five cubic centimeter volume of bacteriorhodopsin studded polymer could theoretically store 512 gigabytes of information. Whereas a 36 cubic centimeter DIMM (dual in-line memory module) cu...

  • Fine-tuning optimistic simulation

    Publication Year: 2000, Page(s):30 - 33

    The chief characteristic that differs markedly between parallel simulation techniques is how they manage process interaction. The linear control models for online configuration of the simulation presented in this article are different from traditional control theory. The reason is because data sampling and parameter adjustment are intrusive; these operations contend for processor cycles that can b... View full abstract»

    Multilayer silicon solar cells are very promising structures for high efficiency photovoltaic conversion. The author discusses the basic principles of solar cell operation and how to maximise the output power and current. However, one problem is the series resistance resulting from the thinness of the layers and the lateral contacts. Sophisticated computations can be undertaken to simulate and opt...

    OFDM is a powerful modulation technique that increases bandwidth efficiency and simplifies the removal of distortion, due to a multipath channel. Advances in fast Fourier transform technology enable OFDM to be efficiently implemented in hardware, even for a large number of subbands. OFDM is currently being used for a number of different applications. This increased popularity will lead to exciting... View full abstract»

  • Can deregulated power bring happiness

    Publication Year: 2000, Page(s):39 - 40

    The question is no longer, “Should the electric power industry be deregulated?” Instead, the questions now are: “how soon? to what extent? and, how do we get there from here?” The longer-term benefits promised are lower prices, more customer choice and innovation. But what about the short-term impacts on everyone en-route? The author discusses both the short and long-term i... View full abstract»
