Linear current-voltage pattern, has been and continues to be the basis for characterizing, evaluating performance, and designing integrated circuits, but is shown not to hold its supremacy as channel lengths are being scaled down. In a nanoscale circuit with reduced dimensionality in one or more of the three Cartesian directions, quantum effects transform the carrier statistics. In the high electr…
Combining both fundamental principles and real-life applications in a single volume, this book discusses the latest research results in ferroelectrics, including many new ferroelectric materials for the latest technologies, such as capacitors, transducers and memories. The first two chapters introduce dielectrics and microscopic materials properties, while the following chapter discusses pyroelect…
A comprehensive and systematic treatment of our current understanding of the microfluidic technique and its advantages in the controllable fabrication of advanced functional polymeric materials. Introducing and summarizing recent advances and achievements in the field, the authors cover the design and fabrication of microfluidic devices, the fundamentals and strategies for controllable microfluidi…
Provides a concise and thorough reference for designing electrical and electronic systems that employ adjustable speed drives Electrical and electronic systems that employ adjustable speed drives are being increasingly used in present-day automation applications. They are considered by many application engineers as one of the most interfering components, especially in a contemporarily faced indust…
Focusing on basic aspects of future reusable space transportation systems and covering overall design, aerodynamics, thermodynamics, flight dynamics, propulsion, materials, and structures, this report presents some of the most recent results obtained in these disciplines. The authors are members of three Collaborative Research Centers in Aachen, Munich and Stuttgart concerned with hypersonic vehic…
Process vent header collection systems are subject to continually varying compositions and flow rates and thus present significant challenges for safe design. Due to increasingly demanding safety, health, environmental, and property protection requirements, today's industrial designers are faced with the need to create increasingly complex systems for more effective treatment, dispersal, or dispos…
Human Factors Methods for Improving Performance in the Process Industries provides guidance for managers and plant engineering staff on specific, practical techniques and tools for addressing forty different human factors issues impacting process safety. Human factors incidents can result in injury and death, damage to the environment, fines, and business losses due to ruined batches, off-spec pro…
Next generation wireless is not about technology, it is all about marketing…. What is the service offering rather than the features of the latest handset? Who are the customers and which are the most profitable? How do you identify and market to communities? How do you tariff for profit? If you need to know the answers and more, you really need to read this book. In the 1990s mobile operators unde…
This book provides the first overview of the service technologies available to telecoms operators working in a post-convergence world. Previous books have focused either on computer networks or on telecoms networks. This is the first to bring the two together and provide a single reference source for information that is currently only to be found in disparate journals, tool specifications and stan…
Access to the Internet is an increasing problem in many areas of the world. As the popularity and usefulness of the Internet increases on a daily basis, lack of access to the technology is putting many groups at a disadvantage in terms of better education, better jobs and even in terms of higher levels of civic participation. However, creating a network infrastructure to serve outlying communities…
IP (internet protocol) Telephony, enabled by softswitches, is going to usher in a new era in telecommunications. By putting voice and data over one IP network, operators can enjoy lower costs and create new, revenue-generating «multimedia» services. This valuable reference offers a comprehensive overview of the technology behind IP telephony and offers essential information to network engineers, d…
The present information age is enabled by telecommunications and information technology and the continued convergence of their services, technologies and business models. Within telecommunications, the historic separations between fixed networks, mobile telephone networks and data communications are diminishing. Similarly, information technology and enterprise communications show convergence with …
Parlay will enable rapid and cost-effective delivery of services based on telecommunications networks, and will be an essential part of the 3G future. We live in an exciting time. 3G networks are taking off, and as greater bandwidth and communication speeds become available, people are seeking new means by which to increase their interaction potential. Newer and more exciting services are being de…
