There is great potential for communication, industrial, scientific, and medical use of electromagnetic fields and radiation. To help advance knowledge of the biological effects of such fields and to exploit their potential medical applications, this book highlights critical issues relating to their effects on living systems.
The widespread impact of these new wireless technologies has raised concerns about the safety of human exposure to radio-frequency (RF) energy emitted by these telecommunication devices. A better understanding of the biological effects of RF electromagnetic field is needed to safeguard against possible harm to the general population. Fortunately in recent years there has been a resurgence of research interest in achieving a quantitative understanding of the relationships between the biological effects of RF radiation and the physical variables that may cause them. A significant number of results have and are beginning to appear in the literature. This volume reviews and assesses the biological effects of exposure to electromagnetic fields from wireless communication technology.
First, there is a brief overview of the history and development of the spectroscope. This is followed by a short introduction to the theory of stellar spectra. The final parts of this section provide details of the necessary reference spectra required for instrument testing and spectral comparison. It concludes with a chapter covering the various types of spectroscopes available to the amateur.
Next, there is a series of "How to..." sections. These cover all aspects of setting up and using various types of commercially available and home-built spectroscopes. Transmission gratings are covered first, and then more complex models, all the way to the sophisticated Littrow design.
The final part of Astronomical Spectroscopy for Amateurs is about practical spectroscope design and construction. It contains a collection of detailed instructions covering the design and building of three different types of spectroscope, along with the necessary design theory (with minimal math). Developing an instrument in simple steps from the basic grating spectroscope, using standard "off the shelf" adaptors, the author describes how to build spectroscopes equal in performance to the better commercial units, constructed using basic hand tools for a fraction of the cost!
This is the only up-to-date practical spectroscopy book available to amateurs. For the first time, it also brings together an invaluable user knowledge base – a collection of observing, analyzing, and processing hints and tips that will allow the amateur to build up and develop important skills in preparing scientifically acceptable spectral data, which can make a valuable contribution to ProAm (professional/amateur) projects. It covers in detail all aspects of the design, construction techniques, testing, calibrating, and using a spectroscope – enough detail to enable the average amateur astronomer to successfully build and use his own spectroscope for a fraction of the current commercial cost.
This book is an ideal complement to Robinson’s Spectroscopy: the Key to the Stars (Springer 2007) and Martin’s Spectroscopic Atlas of Bright Stars (Springer, due 2009). Together, the three books form a complete package for all amateur astronomers who are interested in practical spectroscopy.
As Professor Chris Kitchin said, "If optical spectroscopy had not been invented then fully 75 percent of all astronomical knowledge would be unknown today, and yet the subject itself receives scant attention in astronomical texts." Olivier Thizy (of Shelyak Instruments, the builder of the LiHiResIII commercial spectroscope) writes on an Internet forum; "What is missing is tutorial books and "how to" books with amateur equipment? I believe spectroscopy is in general moving from builders to users (as CCD cameras did in the 1990's)... ...literature is following but slowly."
This is the practical spectroscopy book that amateur astronomers have been waiting for!

Video decoding is an example of an application domain with increasing computational requirements every new generation. This is due, on the one hand, to the trend towards high quality video systems (high definition and frame rate, 3D displays, etc) that results in a continuous increase in the amount of data that has to be processed in real-time. On the other hand, there is the requirement to maintain high compression efficiency which is only possible with video codes like H.264/AVC that use advanced coding techniques.
In this book, the parallelization of H.264/AVC decoding is presented as a case study of parallel programming. H.264/AVC decoding is an example of a complex application with many levels of dependencies, different kernels, and irregular data structures. The book presents a detailed methodology for parallelization of this type of applications. It begins with a description of the algorithm, an analysis of the data dependencies and an evaluation of the different parallelization strategies. Then the design and implementation of a novel parallelization approach is presented that is scalable to many core architectures. Experimental results on different parallel architectures are discussed in detail. Finally, an outlook is given on parallelization opportunities in the upcoming HEVC standard.
Due to its inherent time-scale locality characteristics, the discrete wavelet transform (DWT) has received considerable attention in digital signal processing (speech and image processing), communication, computer science and mathematics. Wavelet transforms are known to have excellent energy compaction characteristics and are able to provide perfect reconstruction. Therefore, they are ideal for signal/image processing. The shifting (or translation) and scaling (or dilation) are unique to wavelets. Orthogonality of wavelets with respect to dilations leads to multigrid representation.
The nature of wavelet computation forces us to carefully examine the implementation methodologies. As the computation of DWT involves filtering, an efficient filtering process is essential in DWT hardware implementation. In the multistage DWT, coefficients are calculated recursively, and in addition to the wavelet decomposition stage, extra space is required to store the intermediate coefficients. Hence, the overall performance depends significantly on the precision of the intermediate DWT coefficients.This work presents new implementation techniques of DWT, that are efficient in terms of computation requirement, storage requirement, and with better signal-to-noise ratio in the reconstructed signal.

About the Author
Steven M. Kay is a Professor of Electrical Engineering at the University of Rhode Island and a leading expert in signal processing. He has received the Education Award "for outstanding contributions in education and in writing scholarly books and texts..." from the IEEE Signal Processing society and has been listed as among the 250 most cited researchers in the world in engineering.
The author has maintained two open-source MATLAB Toolboxes for more than 10 years: one for robotics and one for vision. The key strength of the Toolboxes provide a set of tools that allow the user to work with real problems, not trivial examples. For the student the book makes the algorithms accessible, the Toolbox code can be read to gain understanding, and the examples illustrate how it can be used —instant gratification in just a couple of lines of MATLAB code. The code can also be the starting point for new work, for researchers or students, by writing programs based on Toolbox functions, or modifying the Toolbox code itself.
The purpose of this book is to expand on the tutorial material provided with the toolboxes, add many more examples, and to weave this into a narrative that covers robotics and computer vision separately and together. The author shows how complex problems can be decomposed and solved using just a few simple lines of code, and hopefully to inspire up and coming researchers. The topics covered are guided by the real problems observed over many years as a practitioner of both robotics and computer vision. It is written in a light but informative style, it is easy to read and absorb, and includes a lot of Matlab examples and figures. The book is a real walk through the fundamentals of robot kinematics, dynamics and joint level control, then camera models, image processing, feature extraction and epipolar geometry, and bring it all together in a visual servo system.

The book is designed as a teaching text for the senior undergraduate and postgraduate student, and as a fundamental treatment for those engaged in research using digital image processing in remote sensing. The presentation level is for the mathematical non-specialist. Since the very great number of operational users of remote sensing come from the earth sciences communities, the text is pitched at a level commensurate with their background.
Each chapter covers the pros and cons of digital remotely sensed data, without detailed mathematical treatment of computer based algorithms, but in a manner conductive to an understanding of their capabilities and limitations. Problems conclude each chapter.
This comprehensive, reader-friendly volume offers readers a high-level orientation, discussing the foundations of the field and presenting both the classical work and the most recent results. It covers an extremely rich array of topics including not only syntax and semantics but also phonology and morphology, probabilistic approaches, complexity, learnability, and the analysis of speech and handwriting.
As the first text of its kind, this innovative book will be a valuable tool and reference for those in information science (information retrieval and extraction, search engines) and in natural language technologies (speech recognition, optical character recognition, HCI). Exercises suitable for advanced readers are included as well as suggestions for further reading and an extensive bibliography.
"I'm pleased and impressed. The book is very readable, often entertaining---it tells what the issues are, what they are called, in what health they are, where more meat can be found. Given the enormous amount of material and concepts touched on, and the technical difficulties lying under the surface almost everywhere, the book betrays scholarship in a matter-of-fact way, making due impression on, but without clobbering, the reader. This is a book that invites READING THROUGH...".
