Book: Statistical Image Processing and Multidimensional Modeling

Author:

Pages: 454

Format: PDF

Language: English

ISBN10: 1441972935

Images are all around us! The proliferation of low-cost, high-quality imaging devices has led to an explosion in acquired images. When these images are acquired from a microscope, telescope, satellite, or medical imaging device, there is a statistical image processing task: the inference of something—an artery, a road, a DNA marker, an oil spill—from imagery, possibly noisy, blurry, or incomplete.
A great many textbooks have been written on image processing. However this book does not so much focus on images, per se, but rather on spatial data sets, with one or more measurements taken over a two or higher dimensional space, and to which standard image-processing algorithms may not apply.
There are many important data analysis methods developed in this text for such statistical image problems. Examples abound throughout remote sensing (satellite data mapping, data assimilation, climate-change studies, land use), medical imaging (organ segmentation, anomaly detection), computer vision (image classification, segmentation), and other 2D/3D problems (biological imaging, porous media).
The goal, then, of this text is to address methods for solving multidimensional statistical problems. The text strikes a balance between mathematics and theory on the one hand, versus applications and algorithms on the other, by deliberately developing the basic theory (Part I), the mathematical modeling (Part II), and the algorithmic and numerical methods (Part III) of solving a given problem. The particular emphases of the book include inverse problems, multidimensional modeling, random fields, and hierarchical methods.

Book: New Methods of Concurrent Checking

Author:

Pages: 184

Format: PDF

Language: English

ISBN10: 1402084196

Written by a team of two leading experts and two very successful young former PhD students, New Methods of Concurrent Checking describes new methods of concurrent checking, such as partial duplication, use of output dependencies, complementary circuits, self-dual parity, self-dual duplication and others. A special chapter demonstrates how the new general methods of concurrent checking can be more specifically applied to regular structures to obtain optimum results. This is exemplified for all types of adders up to 64 bits with a level of detail never before presented in the literature. The clearly written text is illustrated by about 100 figures.
New Methods of Concurrent Checking is approved in many university courses for graduate and undergraduate students, and it is of interest to students and teachers in electrical engineering and computer science, researchers and designers and all readers who are interested in the design and the understanding of reliable circuits and computers.

Inverse problems have been the focus of a growing number of research efforts over the last 40 years-and rightly so. The ability to determine a "cause" from an observed "effect" is a powerful one. Researchers now have at their disposal a variety of techniques for solving inverse problems, techniques that go well beyond those useful for relatively simple parameter estimation problems. The question is, where can one find a single, comprehensive resource that details these methods?The answer is the Inverse Engineering Handbook. Leading experts in inverse problems have joined forces to produce the definitive reference that allows readers to understand, implement, and benefit from a variety of problem-solving techniques. Each chapter details a method developed or refined by its contributor, who provides clear explanations, examples, and in many cases, software algorithms. The presentation begins with methods for parameter estimation, which build a bridge to boundary function estimation problems. The techniques addressed include sequential function estimation, mollification, space marching techniques, and adjoint, Monte Carlo, and gradient-based methods. Discussions also cover important experimental aspects, including experiment design and the effects of uncertain parameters.While many of the examples presented focus on heat transfer, the techniques discussed are applicable to a wide range of inverse problems. Anyone interested in inverse problems, regardless of their specialty, will find the Inverse Engineering Handbook to be a unique and invaluable compendium of up-to-date techniques.

Fossil fuels are widely used for electricity generation and heating, creating greenhouse gas emissions and other toxic pollutants, which should be minimised according to the most recent environmental legislation. The utilisation of solid fuels with biogenic origin could contribute to the minimisation of these emissions. Solid Biofuels for Energy presents the current status of the engineering disciplines in this specific area, providing an improved background on the energy exploitation options of solid biomass. Within this framework, all thematic priorities related to the solid bioenergy potential and standardisation, commercialised and emerging energy technologies, and quality of solid residues are presented. Special attention has been given to biomass co-firing with coal, since it has the highest potential for commercial application, while combustion and gasification are more promising for units of medium to small scale. This strong practical focus is evident throughout the book, particularly in discussions of: • international standards for solid biofuel specifications; • supply, cost and sustainability of solid biofuels; • technical issues and non-technical barriers in biomass/coal co-firing; and • biomass combustion and gasification characteristics. Solid Biofuels for Energy is an informative reference, written for researchers and postgraduate students working in the field of biomass. It can also be a useful guide for chemical and mechanical engineers, involved in the environment and energy production sectors.

ISBN10: 0309141451

Energy production and use touch our lives in countless ways. We are reminded of the cost of energy every time we fill up at the gas pump, pay an electricity bill, or purchase an airline ticket. Energy use also has important indirect impacts, not all of which are reflected in current energy prices: depletion of natural resources, degradation of the environment, and threats to national security arising from a growing dependence on geopolitically unstable regions for some of our energy supplies. These indirect impacts could increase in the future if the demand for energy rises faster than available energy supplies. Our nation's challenge is to develop an energy portfolio that reduces these impacts while providing sufficient and affordable energy supplies to sustain our future economic prosperity.
The United States has enormous economic and intellectual resources that can be brought to bear on these challenges through a sustained national effort in the decades ahead. America's Energy Future is intended to inform the development of wise energy policies by fostering a better understanding of technological options for increasing energy supplies and improving the efficiency of energy use. This summary edition of the book will also be a useful resource for professionals working in the energy industry or involved in advocacy and researchers and academics in energy-related fields of study.
America's Energy Future examines the deployment potential, costs, barriers, and impacts of energy supply and end-use technologies during the next two to three decades, including energy efficiency, alternative transportation fuels, renewable energy, fossil fuel energy, and nuclear energy, as well as technologies for improving the nation's electrical transmission and distribution systems.

The electricity power utilities in many countries have been, or are being, restructured. There are many reasons for restructur~ng,I n some countries restruc~uringh as been driven by the desire of gove~mentto meet ~ncreasingd emands for electricity by encouraging independent power production, which relieves government of a financial obligat~on. In countries where ownership of assets is in private hands, restructuring has been driven by mergers and ac~Liisi~ioans~ c,o mpanies seek to gain competiti~ea dvantage. In the most a ~ v a n cco~un tries, restruciuring is being driven by the desire to allow consu~er sto choose their electricity supplier on the basis of price and service provided~ These drarna~~chca nges in the organisation of electricity power utilities bring with them new challenges and opportunities, as the previous centrally designed and operated systems are dismantleda nd replace by a new competitive framework.

Synchronization in Coupled Chaotic Circuits & System by Chai Wah Wu
This invaluable book studies synchronization of coupled chaotic circuits and systems, as well as its applications. It shows how one can use stability results in nonlinear control to derive synchronization criteria for coupled chaotic circuits and systems. It also discusses the use of Lyapunov exponents in deriving synchronization criteria. Both the case of two coupled systems and the case of arbitrarily coupled arrays of systems are considered. The book examines how synchronization properties in arrays of coupled systems are dependent on graph-theoretical properties of the underlying coupling topology. Finally, it studies some applications of synchronized chaotic circuits and systems, including spread spectrum and secure communications, coupled map lattices and graph coloring.

ISBN10: 0387226591

The subject of the book is optoelectronic devices. These are semiconductor devices that employ the interaction of electrons and photons in order to transform electrical into optical signals and vice versa. The large variety of devices, materials, and theoretical approaches often makes it difficult for an experimental researcher to select the appropriate software. Therefore, this book presents a review of devices and approaches, written by leading software providers, in collaboration with partners in the industry or academia. The target audience is students, device engineers, and researchers who are not familiar with the theory behind the software. Each chapter will provide an easy-to-understand introduction to the physics and the main equations, as well as material parameters essential for realistic simulations. The goal is to enhance the general understanding, acceptance, and use of numerical simulations.
The most essential part of this book project is to make it easy for the reader to actually perform advanced simulations himself/herself. Each software package discussed in the book will be available for download in a trial/demo version. This way, every reader is quickly able to repoduce and build on the results shown in the book.

ISBN10: 0792346912

This book is intended for designers of military and civil systems, such as systems for guiding and control, target acquisition, surveillance, laser range-finding, fiber-optical communications, thermal imaging and the like, as well as for designers of photodetectors for optical signal detection. The first question they face is how to detect an ultimately weak optical signal. This book gives the answer to this most important question. All the main types of photodetectors are considered, from photodiodes (including avalanche photodiodes) to focal plane arrays (FPA). Methods of matching photodetectors with preamplifiers are described. The pair photodetector plus preamplifier is treated as an integrated detection system. Much attention is paid to different types of noise and ways of maximising the signal-to-noise ratio (SNR). Foundations of theory of optimal filtering of photosignals are discussed taking due account of typical shapes of optical signals and noise spectra. Methods for tuning quasi-optimal filters to maximise the SNR are explained. The main problems associated with detection of low-level optical signals are considered: operation of avalanche photodiodes in photon count mode, filtering in the case of charge accumulation in FPA cells, and the effect of the number of pixels and geometry of FPAs on detection. Finally, using the examples of the laser range finder and IR Imager, we give guidelines for calculating the limiting parameters of optoelectronic systems to achieve the highest possible SNR. The book is based on many years' experience by the author and his colleagues in the development of photodetectors and FPAs. The book is aimed at research workers, engineers, students and postgraduates.
