    Even with microwave techniques, however, signal losses in materials and decreased gain and power from solid-state devices become significant obstacles to creating low-cost, high-frequency wireless systems. Perhaps the most dramatic effect occurs when a circuit component becomes a significant fraction of a wavelength. At this point it may begin to function well as an antenna. For microwave and mm-w...

    The semiconductor industry is moving toward submicron and deep submicron (0.5 μm and below) technologies. As the chip size keeps decreasing, the chip capacity keeps increasing. New challenges are appearing on high speed ASIC (Application Specified Integrated Circuit) design. Building a balanced clock tree is now essential for the success of any advanced VLSI (Very Large Scale Integration) ... View full abstract»

    Invented and developed at LLNL (Lawrence Livermore National Laboratory), this inexpensive and highly sensitive radar system produces and samples extremely short pulses of energy. This novel technology is finding dozens of new uses in Laboratory programs and in sensor devices for homes, automobiles, factories, and hospitals. We have invented and patented a fundamentally different type of compact, l... View full abstract»

    Hyperthermia, based on fever therapy as a cancer treatment has basically been abandoned in favor of ionizing radiation. In recent years, however, a renewed interest and effort in hyperthermia has taken place. Microwave radiometry can be used for measuring a patient's temperature. Microwave radiometry applications to breast cancer detection and fluid and blood warming are described. View full abstract»

    Fifty years ago John von Neumann proposed the concept of the stored-program computer in which both instructions and data are confined within the boundaries of a storage device called memory. Today a computer architect is faced with a bewildering variety of memory-types to choose from when implementing this concept in the hardware. The most commonly used storage device is called random-access memor... View full abstract»

    The forensic engineer presents knowledge gained through engineering, education, and experience to a judge and a jury in terms they hopefully will comprehend. For it is the jury who ultimately decides the disputesuch decisions often carry very great consequences. This career is certainly not for everyone. Even extremely competent electrical engineers are sometimes ineffective in a litigious environ... View full abstract»

    Expert systems have found widespread use in alarm processing, short term load forecasting, power system planning, economic dispatch and contingency analysis. Expert systems need a precise description of the power system using a lot of consistent rules. Research going on in this field is aimed at making the expert system adaptive by making it learn from new experiences. This challenge could possibl... View full abstract»

    Most research and development for the United States government is conducted by contractors. However, within the science and technology portion of the federal R&D enterprise, there is a network of laboratories that direct and conduct programs related to specific missions. The Department of Energy uses a system of contractor-operated laboratories, including Lawrence Livermore, Los Alamos, Sandia, an... View full abstract»

    This article presents a model of the admission process in terms of the applications that encapsulate the characteristics of the applicants, and the admissions officers who represent the educational philosophy of the university or college. A statistical correlation-based, scientific study evaluates the proposed model. The parameter design reflects the knowledge and experience acquired during the se... View full abstract»
