    The formulation of rules for the rule base and the application of such rules are discussed. The classification of the load forecast parameters into weather-sensitive and nonweather-sensitive categories is described. The rationale underlying the development of rules for both the one-day and seven-day forecast is presented. This exercise leads to the identification and estimation of parameters relat...

    A traditional description of the video spectrum and a three-dimensional representation of video that is useful in understanding advanced television (ATV) are provided. Component video systems are described highlighting the desirable characteristics, such as no crosstalk between the components that make up the color signal, which virtually all ATV systems seek to achieve. The three categories of AT... View full abstract»

    The authors discuss the use of iterative restoration algorithms for the removal of linear blurs from photographic images that may also be assumed to be degraded by pointwise nonlinearities such as film saturation and additive noise. Iterative algorithms allow for the incorporation of various types of prior knowledge about the class of feasible solutions, can be used to remove nonstationary blurs, ... View full abstract»

  • A heat engine model of a reversible computation

    Using the tools of information theory and thermodynamics, reversible computation at the binary level is modeled as a heat engine operating in a Carnot cycle. The model defines an information-theoretic temperature for a binary system and predicts that reversible computation can be accomplished without the dissipation of energy. However, in the worst-case limit, kT log 2 joules of stored en... View full abstract»

    Two-dimensional spatial light modulators (SLMs) modulate one of the properties of an optical wavefront (amplitude, phase, polarization) as a function of two spatial dimensions and time in response to information-bearing control signals that may be either optical or electrical. These devices form a critical part of optical information processing systems, serving as input transducers as well as perf... View full abstract»
