    There has been a tremendous increase in the amount of information that is available over world wide networks. With this, there has been increased pressure on network service providers to provide increased bandwidth. A potential candidate for next generation technology is the asynchronous transfer mode or ATM. ATM promises to deliver a wider variety and high quality of service to support broadband ...

    Many of the efforts to realize 3D optical memory are still in the research stage. They have yet to show their full potential as a high-capacity and short access-time memory for supercomputers. The author discusses the topics of density, bit pattern optical memory (photon gating, stacked layer), and holographic optical memory including a plane holographic memory, stacked SBN plane holograms, and st...

    Metal-semiconductor-metal photodiodes (MSM) are new class of photodetectors that offer an attractive alternative to conventional photodiodes. The advantage and disadvantages of MSM are discussed. MSM allow very large area detectors to facilitate coupling to optical fibres without degrading the bandwidth View full abstract»

    Solar power must become the primary source of commercial power for everyone in the world to achieve the same high standard of living. A power system is needed that is independent of Earth's biosphere and provides abundant energy at low cost. To do this mankind must collect dependable solar power in space and reliably send it to receivers on Earth. The Moon is the key. Here, the author details the ... View full abstract»

  • Questionable predictions

    Publication Year: 1996 , Page(s): 12 - 16

    Examples of inaccurate or questionable predictions exist in the economic, political, social and scientific fields. Predictions about the future states of dynamic physical systems fare somewhat better if the model is accurately known, and if the future inputs are known, at least in an accurate statistical sense. Some procedures, parameters and assumptions that go into prediction have been discussed... View full abstract»

    In Poland, a university is an art and science oriented institution and has no engineering college or engineering departments. Instead, programs of study in engineering are offered by other academic institutions: technical universities (also referred to as universities of technology or polytechnic institutes), technical academies, and engineering colleges. There are 22 engineering schools in Poland... View full abstract»

  • Superconductivity/YBCO

    Since the beginning, it has been clear that superconductors with higher critical temperatures would be more useful and practical. The early superconductors with Tc below 20 K required cooling with liquid helium which boils at a chilly 4.2 K and is quite expensive. If higher temperature superconductors could be found with, say, a Tc of about 100 K, then they could be cooled wi... View full abstract»

    Engineers have been proposing a new class of electronic devices that utilize quantum-mechanical principles (as opposed to classical principles) for their operation. These devices are often referred to as quantum devices or nanoelectronic devices since their physical dimensions are typically smaller than 100 nm. The granularity of electric charge (namely that it can be found only in quanta of a sin... View full abstract»

    Optical switching systems need not be thought of merely as rapid substitutions for electronic devices. On the contrary, the greatest benefit of optical switches could come from applications that cannot be duplicated by other means. Optical fibers, which can carry prodigious amounts of information, are being used increasingly for communications among computers. Optical switching is a natural candid... View full abstract»
