    The theft of US military information from Internet the research computer network built around the Defense Advanced Research Projects Agency's ARPAnet for academic use, is cited as an example of the computer break-ins that are focusing attention on computer security. The nature and extent of the threat are explored, and steps to combat it are described. Among them are encryption, smart cards, and f... View full abstract»

    An explanation is given of logic synthesis, a design methodology whereby the designer begins by describing a design's behavior in high-level code, and capturing its intended functionality rather than its implementation. Once the functionality has been thoroughly verified through simulation, the designer reformulates the design in terms of large structural blocks. The resulting description is calle...

    An emerging solid-state battery that could be fabricated much thinner than 100 mu m and that uses a solid polymer electrolyte as the ionically conducting medium instead of a liquid electrolyte is described. Such batteries combine high energy density with mechanical ruggedness for applications ranging from smart cards to space. The major problem in developing using solid-state batteries has been id...

    The generation of electrostatic discharge (ESD) and the ways in which it causes failure are explained. Three ways of solving ESD problems are described and evaluated. They are: preventing ESD altogether; preventing the coupling of ESD noise into circuits or devices; and increasing the inherent noise immunity of devices and circuits. Firmware and software solutions to ESD upsets are also considered... View full abstract»

    Most urban utilities in the northeast and midAtlantic regions lack sufficient generation to meet their peak loads, and in the summer rely on daily imports in the hundreds of megaWatts from other utilities with power to sell. Since extensive transmission networks mean more reactive power losses, utilities are increasingly turning to capacitor banks, which can be installed close to inductive loads, ... View full abstract»
