    Computer based process control systems have been used successfully for a number of years. However, these systems are often highly mathematical, are difficult to understand and implement, and are also inflexible. Fuzzy logic was developed in the early to mid 1960s by Lotfi Zadeh as an alternative to these complex traditional computer control schemes. Zadeh saw fuzzy logic as a way to achieve proces...

  • Circuit representation in a logic grammar

    Publication Year: 1995, Page(s):28 - 34
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (388 KB)

    We have developed a new framework to represent circuit structures. A circuit is viewed as a sentence, and its elements as words. Circuit structures are defined by a logic grammar called DCSG (definite clause set grammars), developed for analyzing free word-order language. A set of grammar rules itself forms a logic program which implements top-down parsing. Using the grammar rules, given circuits ... View full abstract»

    Fuzzy logic was first developed by Zadeh in the mid 1960s for representing uncertain and imprecise knowledge. In the classical Boolean logic truth is represented by the 1 state and falsity is by the 0 state. Boolean algebra has no provision for approximate reasoning. Fuzzy logic is an extension of Boolean logic in the sense that it also provides a platform for handling uncertain and imprecise know... View full abstract»

    Linear model based beamforming techniques (e.g. MUSIC, MLM, MVDR, etc.) have been widely used for direction-of-arrival (DOA) estimation which, in terms of statistics, only make use of the first and second order moment information (e.g. the mean and the variance) of the data. In these techniques, the higher order statistics (3rd and 4th order “cumulants”) that provide the information re... View full abstract»

    Inverse synthetic aperture radar (ISAR) images generated of targets which have a large angle of rotation or non-linear rotational motion are blurred if the rotational motion is not taken into account. If the rotational motion is known, the data can be corrected by resampling from the polar grid on which the data is collected, to a rectangular grid. A focused ISAR image can be then formed by using ... View full abstract»
