  • Lotfi Zadeh, the father of fuzzy logic, coined the phrase computing with words (CWW) to describe a methodology in which the computation objects are words drawn from a natural language. This text explains how to implement CWW for making subjective judgments using the three components of a Perceptual Computer (encoder, CWW engines, and decoder) and then providing detailed applications. The coverage divides the content into application chapters and detail chapters, including brief summaries of detail chapters for readers more interested in applications.

  • Consideration of the question of meaning in the framework of linguistics often requires an allusion to sets and other higher-order notions. The traditional approach to representing and reasoning about meaning in a computational setting has been to use knowledge representation sys 7 tems that are either based on first-order logic or that use mechanisms whose formal justifications are to be provided after the fact. In this paper we shall consider the use of a higher-order logic for this task. We first present a version of definite clauses (positive Horn clauses) that is based on this logic.

  • What is a computer? A computer may be defined as a machine which accepts data from an input device, processes it by performing arithmetical and logic operations in accordance with a program of instructions and returns the results through an output unit. A computer is basically an electronic machine operating on current.

  • Many recent texts place instructors in the difficult position of chosing between authoritative, state-of-the art coverage and an approach that is highly supportive of student learning. This carefully developed text was widely praised by reviewers for both its great clarity and its rigor. The book balances theory and practice in depth without getting bogged down in excessive technical or mathematical language and has abundant coverage of current topics of interest, such as programmable devices, computer-aided design, and testability.

  • The textbook used by my predecessors assumed the reader had had some experience with electronics. The author went so far as to use screen captures from oscilloscopes and other test equipment to describe circuit properties. I soon found that this was a bad assumption to make when it came to students of computer science.

  • Logic (from the Greek λογική, logikē)[1] has two senses; it is the study of modes of reasoning (those which are valid, and those which are fallacious)[2][3] as well as the use of valid reasoning. In the latter sense, logic is used in most intellectual activities, including philosophy and science, but in the first sense, it is primarily studied in the disciplines of philosophy, mathematics, semantics, and computer science. It examines general forms that arguments may take. In mathematics, it is the study of valid inferences within some formal language.

  • Algorithm is used to define the notion of decidability. It is a set of rules that precisely defines a sequence of operations. This is essential for computers to process information. Computer programs contain algorithms that detail specific instructions a computer should perform to carry out a specified task. The traditional computer program performs specific instructions sequentially, and uses crisp values of information which do not support uncertainties.

  • Consolidation of applications in cloud computing environments presents a significant opportunity for energy optimization. As a first step toward enabling energy efficient consolidation, we study the inter-relationships between energy consumption, resource utilization, and performance of consolidated workloads. The study reveals the energy performance trade-offs for consolidation and shows that optimal operating points exist. We model the consolidation problem as a modified bin packing problem and illustrate it with an example.

  • The study of parallel computing is just about as old as that of computing itself. Indeed, the early machine architects and programmers (neither category would have described themselves in these terms) recognised no such delineations in their work, although the natural human predilection for describing any process as a sequence of operations on a series of variables soon entrenched this philosophy as the basis of all normal systems.
