Taschenbuch. Condizione: Neu. Neuware - Control system power and grounding is possibly the single most important element to ensure a control system doesn't experience unidentified 'gremlins' throughout its life. The topic is appropriate to every control system domain, including programmable logic controllers, process control systems, robotics, vision systems, etc. Power and grounding is recognized by a major industry standards organization, ISA, in ongoing standards efforts.Control Engineering and several power and grounding experts have developed this control system power and grounding resource. When used in conjunction with control system manufacturer installation documentation, users can expect robust, reliable control system installation; one that remains free of 'phantom' problems caused by power and grounding glitches.

Taschenbuch. Condizione: Neu. Neuware - The peripheral component interconnect (PCI) bus is the dominant bus system used to connect the different elements making up today's high-performance computer systems. Different PCI implementations have also been developed for such applications as telecommunications and embedded computing. If an application calls for high speed, high reliability, flexible configuration, and bus mastering, then PCI is the only logical bus choice. This book is an applications-oriented introduction to the PCI bus, with an emphasis on implementing PCI in a variety of computer architectures. Special attention is given to industrial and mission-critical applications of PCI bus.

Buch. Condizione: Neu. Neuware - The book is devoted to various constructions of sets which are nonmeasurable with respect to invariant (more generally, quasi-invariant) measures. Our starting point is the classical Vitali theorem stating the existence of subsets of the real line which are not measurable in the Lebesgue sense. This theorem stimulated the development of the following interesting topics in mathematics:1. Paradoxical decompositions of sets in finite-dimensional Euclidean spaces;2. The theory of non-real-valued-measurable cardinals;3. The theory of invariant (quasi-invariant)extensions of invariant (quasi-invariant) measures.These topics are under consideration in the book. The role of nonmeasurable sets (functions) in point set theory and real analysis is underlined and various classes of such sets (functions) are investigated . Among them there are: Vitali sets, Bernstein sets, Sierpinski sets, nontrivial solutions of the Cauchy functional equation, absolutely nonmeasurable sets in uncountable groups, absolutely nonmeasurable additive functions, thick uniform subsets of the plane, small nonmeasurable sets, absolutely negligible sets, etc. The importance of properties of nonmeasurable sets for various aspects of the measure extension problem is shown. It is also demonstrated that there are close relationships between the existence of nonmeasurable sets and some deep questions of axiomatic set theory, infinite combinatorics, set-theoretical topology, general theory of commutative groups. Many open attractive problems are formulated concerning nonmeasurable sets and functions.
