    Gradually, problem solving becoming dynamic agents interacting with the surrounding world rather than by isolated operations. Some methods are coming from nature, where organisms both cooperate and compete for environmental resources. This has led to the design of algorithms which simulate these natural processes. The genetic algorithm (GA) represents one of the most successful approaches. Genetic... View full abstract»

    The spin transistor is a trilayer, three terminal device similar in some ways to a semiconductor bipolar transistor. Although the physical principles of operation are different, the language of semiconductor physics is borrowed to facilitate the description. The emitter and collector layers of the spin transistor are ferromagnetic films characterized by a magnetization that lies in the plane of th... View full abstract»

    Today, more than ever, photovoltaic energy seems to be on its way to becoming a leading source of electrical power. Prices are dropping and photovoltaic power systems are improving in quality, reliability, and capacity to convert sunlight directly into electricity. One large purchaser of photovoltaics are electric utilities. Here, the author examines the prospects of PV power generation and outlin... View full abstract»

    Perfecting thin film growth techniques have made possible today's search for new, ultrafast optoelectronic devices. The techniques include: molecular beam epitaxy (MBE), organometallic chemical vapor deposition (OMCVD) and atomic layer epitaxy (ALE). By using these methods, scientists and engineers can grow multilayered semiconductor structures of different materials, with extremely high purity, s... View full abstract»

    Describes how the authors used genetic algorithms (GAs) to make a computer develop its own strategy in playing a simple board game. There are various types of games. John von Neumann and Oskar Morgenstern's Game Theory classifies games into several categories depending on the number of players involved, the presence or absence of the element of chance, the case that all players receive the same pi...

    There is hardly a dynamic computer graphics demonstration that does not involve bouncing objects of some sort. Anticipating on-screen collisions does induce adrenalin flow and may explain the attention passers-by give such displays. Usually this visual realism is achieved without regard to the underlying physics of collisions. These displays possess no value other than being attention getters and ... View full abstract»

    There is a growing need for lightweight, durable materials in industry and research. The "classic" materials such as gold, copper, and steel can not fit this new need. Thus, new sets of materials are being used more frequently, and none more so than titanium and its oxides-more specifically, titanium dioxide (TiO2). The author discusses the discovery of titanium dioxide and then describ... View full abstract»
