    The importance of running statistically based process, device and circuit simulations is becoming critical to IC design for manufacturing techniques. Thus arises the need for software-based packages that couple statistical techniques to conventional simulators. Monte Carlo techniques have been implemented in various such packages, but the nature of Monte Carlo designs often lead to time-consuming ... View full abstract»

    Modern computer systems often are designed around a bus architecture. This, of course eliminates the need for complete point-to-point interconnection of all the devices attached to the bus. The major hurdle to this system is in resolving the conflicts that arise when more than one device wants to use the bus to communicate at a time. The job of resolving such conflicts is left to bus arbitration c... View full abstract»

    Rain attenuation is the most dominant cause of signal degradation in satellite links operating at Ka-band. This is a particularly serious issue for ground terminal stations located in a sub-tropical region such as state of Florida. Presently, most rain compensation algorithms are based on the use of a fixed, large fade margin to combat occasional deep fades. However, the use of a fixed margin, esp... View full abstract»

  • Modeling three-dimensional acoustic waves in the ocean

    Publication Year: 1994, Page(s):455 - 459
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (212 KB)

    Conventional three-dimensional ocean acoustic modeling ignores Earth flattening, while this effect, as has been shown by Munk et. al. (J. Phys. Oceanogr, 18, 1988, 1876-1898), can not be ignored for long-range transmissions. To take into account the Earth flattening, a new three-dimensional wave equation is derived, in the paper, in terms of a new coordinate system: the ellipsoidal coordinates (ge... View full abstract»
