Fréquemment cités
Page 273 - IF x is A THEN y is B where A and B are linguistic values defined by fuzzy sets on universe of discourse X and Y respectively (abbreviated as A — >• B).
Page 333 - IDN, that provides end-to-end digital connectivity to support a wide range of services, including voice and non-voice services, to which users have access by a limited set of standard multi-purpose user-network interfaces.
Page 146 - Fundamental law which states that the electric force of attraction or repulsion between two point charges is proportional to the product of the charges and inversely proportional to the square of the distance between them.
Page 222 - The energy difference between the top of the valence band and the bottom of the conduction band is called the band gap.
Page 373 - In retreating from precision in the face of overpowering complexity, it is natural to explore the use of what might be called linguistic variables, that is, variables whose values are not numbers but words or sentences in a natural or artificial language. The motivation for the use of words or sentences rather than numbers is that linguistic characterizations are, in general, less specific than numerical ones
Page 228 - A discrepancy between a computed, observed, or measured value or condition and the true, specified, or theoretically correct value or condition.
Page 215 - Electromagnetic interference is "any electromagnetic disturbance that interrupts, obstructs, or otherwise degrades or limits the effective performance of electronics/electrical equipment. It can be induced intentionally, as in some forms of electronic warfare, or unintentionally, as a result of spurious emissions and responses, intermodulation products, and the like".
Page 257 - It is the illumination on a surface one square foot in area on which there is a uniformly distributed flux of one lumen...
