May 19, 2010 by · Leave a Comment 

Product Description

Fundamental Biomedical Technologies features titles in multidisciplinary, technology-driven areas, providing the foundations for breakthrough advances in medicine and biology. The term technology refers, in a vigorously unrestrictive sense, to a broad array of engineering disciplines, the sciences of computation and informatics, mathematical models exploiting and advancing methods of mathematical physics, and the development of novel, experimental discovery devices. Titles in this series are designed and selected to provide high-level visionary input for specialists, while presenting overviews of emerging fields for those in related areas. Volumes in this series aim to provide technologists with the material to gain competent entry into biomedical research and biomedical researchers to understand and embrace novel technological foundations and tools.

Quantum Semiconductor Devices and Technologies

May 19, 2010 by · Leave a Comment 

Product Description
Quantum Effects in Semiconductor Materials and Devices provides a comprehensive overview of the fabrication and operation of nanoscale devices. It begins with a discussion of the critical issue of the relationship between the characteristic separation of energy levels relative to the temperature of operation and the issue of temperature rise due to energy dissipation. A presentation of the device structures that implement memory circuits and lasers with predictable properties is then given before the array of challenges to the current level of fabrication technologies. The following three chapters are devoted to a discussion of the self-organizational techniques that can be used to address these challenges. This is a unique text that not only reviews the current state of the art but also provides a view of the likely developments in this important and rapidly developing field. It is essential reading for all involved in quantum semiconductors.

Computational Surface and Roundness Metrology

May 14, 2010 by · Leave a Comment 

Product Description

“Computational Surface and Roundness Metrology” provides an extraordinarily practical and hands-on approach towards understanding the diverse array of mathematical methods used in surface texture and roundness analysis. The book, in combination with a mathematical package or programming language interface, provides an invaluable tool for experimenting, learning, and discovering the many flavors of mathematics that are so routinely taken for granted in metrology. Whether the objective is to understand the origin of that ubiquitous transmission characteristics curve of a filter we see so often yet do not quite comprehend, or to delve into the intricate depths of a deceptively simple problem of fitting a line or a plane to a set of points, this book describes it all (in exhaustive detail). From the graduate student of metrology to the practicing engineer on the shop floor, this book is a must-have reference for all involved in metrology, instrumentation/optics, manufacturing, and electronics.

From the paper “Suspended metal wire array as a thermoacoustic sound source,” Appl. Phys. Lett. 95, 163102 (2009); by AO Niskanen, J. Hassel, M. Tikander, P. Maijala, L. Grönberg, P. Helistö, from VTT Technical Research Centre of Finland, PO BOX 1000, 02044 VTT, Finland. dx.doi.org A suspended metal wire array is used to produce high-pressure sound waves over a wide spectrum using the thermoacoustic effect. It is fabricated with an air-bridge arrays containing up to 2×105 wires covering an area of a few square centimeters. The supporting silicon wafer was isotropically plasma etched to release the wires thereby avoiding heat contact with the substrate. Sound pressure levels reaching 110 db at a distance of 8 cm were demonstrated near 40 khz in free field. The devices are also able to reproduce music and speech. They have potential for applications especially in the ultrasound range.
