    The author focuses on light detectors and their properties. A classification of detectors is given, and phototubes and photomultiplier-tubes are described. Just as the tubes were classified, so again a distinction can made between solid-state detectors that have an internal gain and detectors that have no internal gain. Detectors with internal gain are the photoconductive detectors, the avalanche ... View full abstract»

    The use of electromagnetic natural resonance as non-cooperative target recognition (NCTR) parameters is quite different from the conventional Doppler-based radar approach and is investigated for use in future radar systems. Natural resonance frequencies contained in a target's radar signature are determined by its structure and serve to identify the target. The physics of natural resonances are de...

    Computer integrated manufacturing (CIM) systems include product design, actual manufacturing of the product, shipping, and even customer product support. The drive toward CIM has three key technical thrusts: flexible automation, information integration, and online optimization. How these three thrusts relate to a manufacturing facility's generic activities is detailed. The authors define manufactu... View full abstract»

    Some background information on superconducting ceramics is given, and the history of yttrium barium copper oxide (YBCO) is discussed. The crystal structure of superconducting YBCO is described. The production and extraction methods of bulk samples of YBCO are detailed. Different theories of superconductivity in YBCO are addressed, and applications of YBCO superconductors are discussed.<> View full abstract»

    The discovery of the cuprate superconducting materials, with critical temperatures exceeding 100 K, has revived interest in hybrid superconductor-semiconductor technology. An elementary definition of a superconductor is given, and superconducting field effect transistors (SuFETs) are presented. The effect of the close proximity of the source and drain electrodes on SuFETs is detailed, and the SuFE... View full abstract»

    The author reflects on the life of Claude Shannon, personally and professionally. The author comments on Shannon's contributions to information theory; the application of Boolean algebra to relay and switching circuits, and in general, to logical design and how Shannon is noted for two papers on how a computer could play chess View full abstract»
