  • Table shortcuts [Laplace transform]

    Publication Year: 1999, Page(s):36 - 37
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (296 KB)

    A useful, but seldom used, Laplace transform pair is revisited. Despite the usefulness of this pair, it has generally been omitted from textbooks that introduce the one-sided Laplace transform. Its generality helps one see the roles of damping factor, natural frequency, and a zero in shaping the transient response of a second order system View full abstract»

  • Parallel computing for less

    High speed networks and improved microprocessor performances are making workstations an appealing prospect for parallel computing. With just commodity hardware and software, networked workstations can offer parallel processing at a relatively low cost. Parallel computing can be implemented in two ways. The networked workstations can be set up as a processor bank with dedicated processors providing... View full abstract»

    Many people use the Web everyday in their jobs. Excluding those whose jobs are to design, implement and maintain a Web infrastructure, most are looking for information. The Web provides an excellent medium for this information exchange and data retrieval. But, the entire World Wide Web (WWW) cannot serve the microscopic tailored needs of an individual's work project. What's more, a large corporati... View full abstract»

  • The peculiar patterns of first digits

    Publication Year: 1999, Page(s):24 - 27

    Despite seeing numbers all the time only occasionally would one say that a list of numbers seems odd. For this to occur, the numbers are typically highly rounded or implausible (too much of a coincidence). However digit pattern analysis, using a computer, can produce valuable findings not revealed at a mere glance. The most widely cited paper on digit frequencies was published by Frank Benford in ...

  • Serial digital video boards

    Publication Year: 1999, Page(s):20 - 23

    An important video format for television broadcast and editing professionals is the 4:2:2 component digital video. This format is available in two forms-parallel and serial. However, the parallel form is on its way out. (The cables are quite bulky and awkward to deal with.) As a result, the serial form is becoming more and more the video format of choice. But, due to the high frequency of this ser... View full abstract»

  • Silicon-germanium

    Publication Year: 1999, Page(s):17 - 19
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (344 KB)

    The strong points of compound and single element semiconductors are united in a new type of transistor, silicon-germanium heterojunction bipolar transistor (Si-Ge HBT). The device is the offshoot of bandgap engineering and the manufacturing economics of silicon. Silicon-germanium is a new material used in making microchips for less expensive, high-performance communications tools. Low energy consu... View full abstract»

  • The blackjack tutor chip

    Develops an application specific chip to advise a blackjack player on the next best move. The chip indicates when the player has blackjack, whether the player should stay or draw, when the player has “busted” and when the player has given a bad value for the dealer's up card. This chip will not likely make a player rich, but it should minimize a player's losses View full abstract»

  • Quantum computation

    Publication Year: 1999, Page(s):4 - 8
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (600 KB)

    Quantum computation is the design of computers in the regime of quantum mechanical phenomena. For those in engineering, the structure of quantum mechanics is most easily grasped as an extension of classical probabilistic processes. To describe the behavior of a classical probabilistic system, we need to define a physical system and specify the probabilities of each state. For example, a coin that ... View full abstract»

  • Wiring like mother nature [antenna design]

    Publication Year: 1999, Page(s):9 - 12

    Today, most antenna designs are simulated numerically rather than analyzed theoretically. A computer program approximates the structure and calculates its properties. Even though very complex designs can be simulated, structures are usually kept simple to allow for easy understanding and analysis. Symmetry is often present. Nearly all the designs “make sense” when one looks at them or ... View full abstract»
