    Genetic algorithms were introduced by John Holland in early 1970s as a special technique for function optimization. They are quite different from other more conventional optimization methods that are mainly stochastic in nature. A typical GA will have three phases; i.e., initialization, evaluation and genetic operation. In each phase, various parameters of GA need to be selected based on the natur... View full abstract»

    Combinatorial optimization problems typically require every possible solution to be evaluated to ensure finding the optimal solution. Since such exhaustive searches are often impractical, there is now a vast body of heuristic algorithms for them. Among the algorithms are those based on metaphors borrowed from other areas of science. The idea is that key elements of physical processes can be used a... View full abstract»

    This brief discussion demonstrates that at least one fundamental property of EM fields, the radiation and propagation of power through space, can be explained without complicated mathematics. Since EM fields would not exist without radiation, this means that understanding EM need not be mathematically intimidating View full abstract»

    Silica aerogels are unique in chemistry and have intrigued scientists and engineers alike. They have distinct properties that are attractive in a number of technologies. Although it has been in existence since 1930, silica aerogels are still fairly new in terms of discovery and research. Aerogel's air-like qualities have been put to use for home insulation to comet catchers. With the right combina... View full abstract»

    One big reason for the poor power quality incidents experienced today is the proliferation of electronic devices. A voracious appetite for higher efficiency and productivity in the manufacturing sector, comfort and automation in homes, and efficient lighting systems in commercial installations are driving the market for power electronic devices. At the forefront of this explosion is the switched p... View full abstract»

    We introduce a design of an associative memory array processor (AMAP) to be used in character recognition. The design example is based upon the bit-parallel organization. The AMAP consists of identical processing elements that can store information about a specific position into the pattern and also contain some logic gates to carry out logical operations. No effort has been made to perform either... View full abstract»

    Workstation clusters have become an increasingly popular alternative to traditional parallel supercomputers for many workloads requiring high performance computing. The use of parallel computing for scientific simulations has increased tremendously in the last ten years, and parallel implementations of scientific simulation codes are now in widespread use. There are two dominant parallel hardware/... View full abstract»

    The advent of modern computer technology has enabled the development of many complex man-made systems. These include discrete manufacturing systems, communication networks, computer systems, traffic control systems, and inventory systems. A common characteristic of these systems is that they have discrete states (e.g., idle, processing, queue empty/full, and normal/faulty). Also, their state trans... View full abstract»

    There are several microwave applications where tunable ferroelectric devices could play a key role in improving system performance, or they could provide the key technology that enables a system to be deployed. This article focuses on the Ka-band phased array antennas, but tunable filters, oscillators, and switches could also utilize these materials View full abstract»
