Three major macroenvironmental forces – security, reliability, and economics -- have combined to change the rules and optimum responses for the management of DC power plant systems. This paper explores the maintenance problems created by these forces, and suggests a strategic approach for maintenance of battery systems based on balancing risk mitigation and budget optimization.
The plasma facing components, first wall and blanket systems of future tokamak-based fusion power plants arguably represent the single greatest materials engineering challenge of all time. Indeed, the United States National Academy of Engineering has recently ranked the quest for fusion as one of the top grand challenges for engineering in the 21st Century. These challenges are even more pronounced...
Many sophisticated high-resolution methods have been proposed. The study describes the practical experience in the combined application of superresolution and autocalibration methods for the resolution of multipath signals. An experimental linear array antenna has been used to perform superresolution after applying autocalibration to signals from one or several radiating sources, for example base...
This paper presents a passive radar system using GSM as illuminator of opportunity. The new feature is the used high performance uniform linear antenna (ULA) for extracting both the reference and the echo signal in a software defined radar. The signal processing steps used by the proposed scheme are detailed and the feasibility of the whole system is proved by measurements.
Identification of Special Nuclear Material (SNM) by Nuclear Resonance Fluorescence is developing as a promising method but is currently limited by available photon sources. A very limited source spectrum (≪ 1 eV width at MeV energies) is ideal. One method of providing this source is by electron excitation of a target containing the nucleus of interest. In this method, however, the photon energy mismatch...
