Taschenbuch. Zustand: Neu. Neuware - Voice Over Internet Protocol Security has been designed to help the reader fully understand, prepare for and mediate current security and QoS risks in today s complex and ever changing converged network environment and it will help you secure your VoIP network whether you are at the planning, implementation, or post-implementation phase of your VoIP infrastructure.\* This book will teach you how to plan for and implement VoIP security solutions in converged network infrastructures. Whether you have picked up this book out of curiosity or professional interest . . . it is not too late to read this book and gain a deep understanding of what needs to be done in a VoIP implementation.\* In the rush to be first to market or to implement the latest and greatest technology, many current implementations of VoIP infrastructures, both large and small, have been implemented with minimal thought to QoS and almost no thought to security and interoperability.

Buch. Zustand: Neu. Neuware - Nuclear Magnetic Resonance (NMR) spectroscopy is a powerful and theoretically complex analytical tool. Basic 1H- and 13C-NMR Spectroscopy provides an introduction to the principles and applications of NMR spectroscopy. Whilst looking at the problems students encounter when using NMR spectroscopy, the author avoids the complicated mathematics that are applied within the field. Providing a rational description of the NMR phenomenon, this book is easy to read and is suitable for the undergraduate and graduate student in chemistry. \* Describes the fundamental principles of the pulse NMR experiment and 2D NMR spectra \* Easy to read and written with the undergraduate and graduate chemistry student in mind\* Provides a rational description of NMR spectroscopy without complicated mathematics.

Buch. Zustand: Neu. Neuware - The book is devoted to universality problems. A new approach to these problems is given using some specific spaces. Since the construction of these specific spaces is set-theoretical, the given theory can be applied to different topics of Topology such as: universal mappings, dimension theory, action of groups, inverse spectra, isometrical embeddings, and so on. .Universal spaces .Universal mappings .Dimension theory .Actions of groups .Isometric Universal Spaces.

Buch. Zustand: Neu. Neuware - There are numerous engineering applications for high-speed rotating structures which rotate about their symmetric axes. For example, free-flight sub-munition projectiles rotate at high speeds in order to achieve an aerodynamically-stable flight.This is the first book of its kind to provide a comprehensive and systematic description of rotating shell dynamics. It not only provides the basic derivation of the dynamic governing equations for rotating shells, but documents benchmark results for free vibration, critical speed and parametric resonance. It is written in a simple and clear manner making it accessible both the expert and graduate student.The first monograph to provide a detailed description of rotating shell dynamics.Dynamic problems such as free vibration and dynamic stability are examined in detail, for basic shells of revolutions.

Buch. Zustand: Neu. Neuware - Batteries for Portable Devices provides a comprehensive overview of all batteries used in portable electric and electronic, as well as medical devices. These range from the cellular phone to portable CD and cardiac pacemakers to remote micro-sensors. The author looks at the behaviour of batteries in the conditions encountered in the above applications. Information on the performance of the most recent commercial batteries are graphically illustrated and comparisons are made. This easy-to-read book also contains useful information on topics rarely discussed in the field, such as battery collection, recycling and market trends. \* Contains an extensive bibliography\* Includes rarely discussed topics, such as battery collection and recycling\* Well illustrated and easy to read.

Buch. Zustand: Neu. Neuware - Interfacial Separation of Particles is concerned with the processing and separation of fine solid particles in liquid solutions using interfacial technology.Interfacial separation has been finding wide application in many industrial fields, such as pigment and filler production, mineral processing, environmental protection, hydrometallurgy, bioengineering, food and beverage industry and chemical industry. This book describes all interfacial separation techniques and discusses the general and specific fundamentals of the techniques. The book intends to promote theoretical understanding and the more promising developments of interfacial separation technology whilst broadening the reader's background knowledge of industrial suspensions. \* Is clearly written based on strong systematic science fundamentals\* Provides comprehensive coverage on particle technology, mineral processing and water treatment\* Includes practical examples from the different industrial fields.
