  • A PLC or programmable controller is a computer based solid state device that controls industrial equipment and processes. Initially designed to perform the logic functions executed by relays, drum switches and mechanical timer/counters, it has been extended to analog control as well. A typical PLC system consists of a processor and an input/output system all mounted in a rack like system. The PLC system is a cost effective solution for applications with a high ratio of digital to analog points in a system.

  • This book will discuss the topic of Control Systems, which is an interdisciplinary engineering topic. Methods considered here will consist of both "Classical" control methods, and "Modern" control methods. Also, discretely sampled systems (digital/computer systems) will be considered in parallel with the more common analog methods. This book will not focus on any single engineering discipline (electrical, mechanical, chemical, etc), although readers should have a solid foundation in the fundamentals of at least one discipline....

  • The state-of-the-art of controlled radical polymerization (CRP) in 2011 is presented. Atom transfer radical polymerization, stable radical mediated polymerization, and degenerate transfer processes, including reversible addition fragmentation chain transfer are the most often used CRP procedures. CRP opens new avenues to novel materials from a large range of monomers. Detailed structure-reactivity relationships and mechanistic understanding not only helps attain a better controlled polymerization but enables preparation of polymers with complex architectures.

  • The major sources of indoor air pollution worldwide include indoor combustion of solid fuels, tobacco smoking, outdoor air pollutants, emissions from construction materials and furnishings, and improper maintenance of ventilation and air conditioning systems. Although some indoor air pollutants, such as environmental tobacco smoke, are of concern globally, profiles of indoor air pollutants and the resulting health risks are generally very different in developed and developing countries.

  • The presence of chlorine in alternative fuels (e.g., sewage sludge, municipal solid waste or incineration ash, chlorinated biomass,) has both direct and indirect implications on cement kiln emissions and performance. Methods have been developed to properly manage chlorine and its potential implications – but it is important that these implications be recognized and managed. Trace levels of chlorine in feed materials can lead to the formation of acidic gases such as hydrogen chloride (HCl) and hydrogen fluoride (HF) (WBCSD 2002).

  • This textbook grew out of a number of undergraduate and graduate courses on logistics and supply chain management that we have taught to engineering, computer science, andmanagement science students.The goal of these courses is to give students a solid understanding of the analytical tools available to reduce costs and improve service levels in logistics systems. For several years, the lack of a suitable textbook forced us tomake use of a number ofmonographs and scientific paperswhich tended to be beyond the level ofmost students.

  • 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.

  • In today’s practical and cost-conscious world, sheet-metal parts have already replaced many expensive cast, forged, and machined products. The reason is obviously the relative cheapness of stamped, or otherwise mass-produced parts, as well as greater control of their technical and aesthetic parameters. That the world slowly turned away from heavy, ornate, and complicated shapes, and replaced them with functional, simple, and logical forms only enhanced this tendency. Remember old bathtubs? They used to be cast and had ornamental legs.

  • This third volume of the book series Lessons In Electric Circuits makes a departure from the former two in that the transition between electric circuits and electronic circuits is formally crossed. Electric circuits are connections of conductive wires and other devices whereby the uniform ow of electrons occurs. Electronic circuits add a new dimension to electric circuits in that some means of control is exerted over the ow of electrons by another electrical signal, either a voltage or a current....

  • This first part is concerned with processes in which the kinetic behaviour of a gaseous phase is rate-determining. The range of processes includes some which are carried out in vacuum systems in which Knudsen or free evaporation occurs from a condensed phase, to transport reactions where a chemical reaction occurs between a solid and the gaseous phase to produce molecular species containing some or all of the elements occurring in the solid phase.

  • Our goal in writing this book is to expose the inner workings of the modern digital computer at a level that demystifies what goes on inside the machine. The only prerequisite to Principles of Computer Architecture is a working knowledge of a high-level programming language. The breadth of material has been chosen to cover topics normally found in a first course in computer architecture or computer organization. The breadth and depth of coverage have been steered to also place the beginning student on a solid track for continuing studies in computer related disciplines....

  • Casting process is the most direct method of producing a product from the chosen material. Though products in all the three major classes of materials, metals, ceramics and polymers can be produced by this method, casting of metals is by far the most widely used process. The basic steps in the casting process are preparation of the material in the liquid state, transferring the liquid material into a shaping mold, allowing the transformation of liquid material in the mold into a solid form.

  • Analysis and abatement of air pollution involve a variety of technical disciplines. Formation of the most prevalent pollutants occurs during the combustion process, a tightly coupled system involving fluid flow, mass and energy transport, and chemical kinetics. Its complexity is exemplified by the fact that, in many respects, the simplest hydrocarbon combustion, the methane-oxygen flame, has been quantitatively modeled only within the last several years.

  • Crystallization is one of the most ancient and interdisciplinary topics of research known to mankind. Crystals can be organic or inorganic and may be produced from melts, liquid solutions, vapors or even in solid state. Notwithstanding its inherently high complexity, the crystallization process is part of our everyday lives, from ice making in our homes to the most state-of-the-art chemical and electronic industry.
