Taschenbuch. Condizione: Neu. Neuware - Security technology convergence, which refers to the incorporation of computing, networking, and communications technologies into electronic physical security systems, was first introduced in the 1970s with the advent of computer-based access control and alarm systems. As the pace of information technology (IT) advances continued to accelerate, the physical security industry continued to lag behind IT advances by at least two to three years. Security Technology Convergence Insights explores this sometimes problematic convergence of physical security technology and information technology and its impact on security departments, IT departments, vendors, and management.

Buch. Condizione: Neu. Neuware - An Applied Guide to Process and Plant Design explains how professional engineers carry out process design in industry. The book covers plant layout and the use of spreadsheet programmes and key drawings as aids to design, subjects which are usually learned on the job rather than in education. Users will learn how to produce tighter plant designs, along with computer tools, including Hysys and AutoCAD that assist in the creative process,'What If Analysis' features, statistical plugins, and visual basic for more complex problems. Professor Moran has pulled together over 20 years of experience in process design to create a foundational book that is ideal for those who are new to process design. It is fully supported with worked examples and case studies in order to assist learning, and is fully compliant with both professional practice and the IChemE degree accreditation guidelines.\* Discusses how to use computer tools and simulation techniques to deliver a process design that meets both the business and safety case\* Covers plant layout and the use of spreadsheet programmes and key drawings as aids to design, subjects which are usually learned on the job rather than in education\* Teachers users how to communicate what their proposed process design project is expected to deliver to managers\* Includes discussions on Hysys and AutoCAD and how they can assist in the creative process.

Buch. Condizione: Neu. Neuware - Electrochemical Micromachining for Nanofabrication, MEMS and Nanotechnology is the first book solely dedicated to electrochemical micromachining (EMM). It begins with fundamentals, techniques, processes, and conditions, continuing with in-depth discussions of mechanisms of material removal, including an empirical model on the material removal rate for EMM (supported by experimental validation). The book moves next to construction-related features of EMM setup suitable for industrial micromachining applications, varying types of EMM, and the latest developments in the improvement of EMM setup. Further, it covers power supply, roll of electrolyte, and other major factors influencing EMM processes, and reports research findings concerning the improvement of machining accuracy and efficiency. Finally, the book devotes a chapter to the design and development of micro-tools, one of the most vital components in EMM.

Buch. Condizione: Neu. Neuware - The book provides a beginners introduction to the way ultrasound acts on bubbles in a liquid to cause bubbles to collapse violently, leading to localised 'hot spots' in the liquid with temperatures of 5000 C and under pressures of several hundred atmospheres. These extreme conditions produce events such as the emission of light, sonoluminescence, with a lifetime of less than a nanosecond, and free radicals that can initiate a host of varied chemical reactions (sonochemistry) in the liquid, all at room temperature. The physics and chemistry behind the phenomena are simply but comprehensively presented. In addition, potential industrial and medical applications of acoustic cavitation and its chemical effects are described and reviewed. The book is suitable for graduate students working with ultrasound and for potential chemists and chemical engineers wanting to understand the basics of how ultrasound acts in a liquid to cause chemical and physical effects. The book is a carefully structured beginners guide to acoustic cavitation phenomena, i.e., the formation and subsequent collapse of micro bubbles in a liquid exposed to ultrasound.Its chemical effects (sonochemistry) are caused by radicals formed inside bubbles during their collapse as a consequence of the extreme temperatures and pressures created within such bubbles. These free radicals are the basis of many chemical reactions, including, electron transfer reactions, new stable compound formation, initiation of polymerization processes, as well as oxidation reactions leading to molecular degradation. The book guides the reader from the physics of how ultrasound interacts with bubbles to applications of sonochemisty. The applications cover industrial (including food processing) and medical uses of ultrasound. It is useful for the user because it consolidates what is known how ultrasound acts on bubbles, and the chemical consequences of its exposure to a broad range of systems. As ultrasound reactors are widely used in both the laboratory and in commercial processes the book provides a useful fundamental understanding on what lies behind the application in action Experimental methods on acoustic cavitation and sonochemistry One can readily begin experiments in the field. Fundamentals One can easily understand the physics behind the phenomenon.Examples of (possible) industrial applications in chemical engineering and environmental technologies One can easily understand the possibilities for adopting the action of acoustic cavitation with respect to industrial applications. Examples of (potential) medical applications One can easily grasp the potential use of the phenomenon to medical applications. Examples in organic and inorganic chemical synthesis One can readily understand the many possibilities for applying cavitation chemistry in chemical synthesis. History One is clearly introduced to the history of the field and its novel developments.
