    The process for simulating a circuit is very similar to testing a hardware prototype circuit with signal generators and logic analyzers. To simulate a circuit, you first specify a set of stimulus signals for the inputs of the circuit. The simulator then propagates these signals through the device models to determine the circuit outputs at each point in time. After a set time, the simulator display... View full abstract»

    The Earth is a tremendously complicated series of atmospheric, oceanic, geologic, and biological processes all working together. Science is striving to create the ultimate closed ecosystem by replicating these dynamic forces on a microcosmic level. From this research, science will gain tremendous knowledge about how to lower costs and add aesthetic appeal for long-term space flight. Also, these mi... View full abstract»

    Error control coding (ECC) is a signal processing technique that protects digital information against transmission and storage errors. Codes that combat randomly distributed errors are called random-error correcting codes. Codes that cope with errors that are clustered together are known as burst-error correcting codes. When data is presented as a stream of binary numbers, bit-oriented codes may b... View full abstract»

    Modern circuit analysis programs (CAP) such as PSPICE and MICROCAP offer efficient and accurate alternatives to more traditional “paper and pencil techniques”. Nevertheless, the ability to quickly analyze circuit behavior without the aid of a computer is an important skill that provides valuable insights into circuit performance. The “paper and pencil” technique presented i... View full abstract»

    The author steps through a simple collision avoidance system designed to automatically warn the driver when the car is in danger of hitting another car (or other object) in front of it. The urgency of the system's warning will depend on the car's speed, its distance to the next car, and the speed of the next car. The design of a fuzzy system can be described in four steps: determination of fuzzy i... View full abstract»

    A pressing area of concern is the future competitiveness of the electronics industry. Design For Environment (DFE) is a method by which environmental considerations and constraints can be integrated into existing process and product design practices. It involves considering the environmental impact of all materials and processes that are involved in the entire life-cycle of the product. The life-c... View full abstract»

    Parallel processing is the harnessing of multiple processors to work on the same problem. The aim is to speed up the computational process, ideally by the number of processors used. Parallel processing is increasingly emerging as the key to very-high-speed computation. This article is an introductory overview emphasizing the use of parallel computers for computational engineering View full abstract»

    Research is a basic element of good sanctuary management. The kinds of research necessary to deal with management problems include: survey and assessment, characterization, monitoring, experimental work, and modeling. The Monterey Bay National Marine Sanctuary is the largest, deepest, and ecologically speaking, perhaps the most complex region for which NOAA's Marine Sanctuary Program has research ...

    The ultimate usefulness of a number system depends on its implementation. Multiple-valued logic has been implemented in charge-coupled devices (CCD). In this technology, logic values are encoded as charge. For example, prototype four-valued logic devices have been implemented at the University of Twente (Enschede, Holland). Hitachi has implemented a 16-valued memory that stores the equivalent of 1... View full abstract»
