This book discusses statistical methods that are useful for treating problems in modern optics, and the application of these methods to solving a variety of such problems This book covers a variety of statistical problems in optics, including both theory and applications. The text covers the necessary background in statistics, statistical properties of light waves of various types, the theory of partial coherence and its applications, imaging with partially coherent light, atmospheric degradations of images, and noise limitations in the detection of light. New topics have been introduced in the second edition, including: Analysis of the Vander Pol oscillator model of laser light Coverage on coherence tomography and coherence multiplexing of fiber sensors An expansion of the chapter on imaging with partially coherent light, including several new examples An expanded section on speckle and its properties New sections on the cross-spectrum and bispectrum techniques for obtaining images free from atmospheric distortions A new section on imaging through atmospheric turbulence using coherent light The addition of the effects of “read noise” to the discussions of limitations encountered in detecting very weak optical signals A number of new problems and many new references have been added Statistical Optics, Second Edition is written for researchers and engineering students interested in optics, physicists and chemists, as well as graduate level courses in a University Engineering or Physics Department.
The concept of an inverse problem is a familiar one to most scientists and engineers, particularly in the field of signal and image processing, imaging systems (medical, geophysical, industrial non-destructive testing, etc.) and computer vision. In imaging systems, the aim is not just to estimate unobserved images, but also their geometric characteristics from observed quantities that are linked to these unobserved quantities through the forward problem. This book focuses on imagery and vision problems that can be clearly written in terms of an inverse problem where an estimate for the image and its geometrical attributes (contours and regions) is sought. The chapters of this book use a consistent methodology to examine inverse problems such as: noise removal; restoration by deconvolution; 2D or 3D reconstruction in X-ray, tomography or microwave imaging; reconstruction of the surface of a 3D object using X-ray tomography or making use of its shading; reconstruction of the surface of a 3D landscape based on several satellite photos; super-resolution; motion estimation in a sequence of images; separation of several images mixed using instruments with different sensitivities or transfer functions; and more.
Beginning with chapters summarizing the basics of diabetic retinopathy, this updated volume outlines the need for screening, how to screen safely and correctly, and the normal condition of the retina without diabetic retinopathy, all using excellent line and halftone illustrations. The core focus then moves on to examining each different form of retinopathy, all supported by outstanding color retinal photographs illustrating the appearance of the retina at various stages of retinopathy, plus an analysis on the best treatment for each stage. The book ends with chapters providing self-assessment questions of the type that screeners will encounter when gaining their now mandatory retinal screening qualifications, as well as a background information chapter offering advice on related UK, European, and US organizations. A website contains all the full-color retinopathy images from the book, with the option to download these into presentations.
The classic approach in Automatic Control relies on the use of simplified models of the systems and reformulations of the specifications. In this framework, the control law can be computed using deterministic algorithms. However, this approach fails when the system is too complex for its model to be sufficiently simplified, when the designer has many constraints to take into account, or when the goal is not only to design a control but also to optimize it. This book presents a new trend in Automatic Control with the use of metaheuristic algorithms. These kinds of algorithm can optimize any criterion and constraint, and therefore do not need such simplifications and reformulations. The first chapter outlines the author’s main motivations for the approach which he proposes, and presents the advantages which it offers. In Chapter 2, he deals with the problem of system identification. The third and fourth chapters are the core of the book where the design and optimization of control law, using the metaheuristic method (particle swarm optimization), is given. The proposed approach is presented along with real-life experiments, proving the efficiency of the methodology. Finally, in Chapter 5, the author proposes solving the problem of predictive control of hybrid systems. Contents 1. Introduction and Motivations. 2. Symbolic Regression. 3. PID Design Using Particle Swarm Optimization. 4. Tuning and Optimization of H-infinity Control Laws. 5. Predictive Control of Hybrid Systems. About the Authors Guillaume Sandou is Professor in the Automatic Department of Supélec, in Gif Sur Yvette, France. He has had 12 books, 8 journal papers and 1 patent published, and has written papers for 32 international conferences.His main research interests include modeling, optimization and control of industrial systems; optimization and metaheuristics for Automatic Control; and constrained control.
In this book, using telepathy as an example, we consider the practical use of some esoteric techniques that open up access to our subconscious. The attached photo album contains numerous images of a mystical character, and if you look closely at them, you can feel the mystical spiritual principle inherent in nature itself.
Handbook of Small Animal MRI will help you make the most of one of the greatest advancements in veterinary practice in recent years, magnetic resonance imaging. Those using the services of mobile scanners dedicated to veterinary use, as well as those in practices with their own MRI machine, will benefit from this book. It provides a clear and comprehensive account of how this important diagnostic tool works. In addition this easy reference handbook provides guidance on the interpretation of images of common clinical conditions. The book includes: • An overview of the basic principles, explaining exactly how and why MRI works and how images are produced • Easy-to-understand diagrams to explain the theory of MRI • Safety procedures • A Glossary of terms • Over 100 annotated images of MRI scans to aid diagnosis • An additional atlas of normal anatomy for MRI interpretation Written by two pioneering experts in the field with a combined experience of over 20,000 MRI studies of veterinary patients. Suitable for small animal veterinarians and veterinary students. Ian Elliott trained as a Radiographer and first became involved with MRI in late 1980s. He has worked exclusively in MRI since 1991 and, following an extensive spell scanning human patients, helped pioneer the use of the technique in veterinary practice. Ian has been involved exclusively in veterinary MRI since 2000 and has scanned many thousands of cases during this time. He currently works for Burgess Diagnostics providing MRI services to veterinary surgeons throughout UK and Ireland. Geoff Skerritt is an RCVS Recognised Specialist in Veterinary Neurology, Diplomate of the European College of Veterinary Neurology and former President of the ECVN. In 1997 Geoff was one of the founders of VetMRI, the first mobile veterinary MRI facility in Europe. He is the founder and director of ChesterGates Animal Referral Hospital, a leading multi-discipline veterinary referral centre in the UK.
The Reading and Writing Booklet includes four pages per unit to target specific skills. The first page focuses on reading, the second on comprehension with more of a range of texts than those offered in the CLIL and Wider World pages of the Pupil's Book. The third page offers reading and writing activities to revise the key vocabulary, and using the fourth page pupils have the opportunity to write texts which practice punctuation, syntax and structure. An answer key is provided at the back of the Teachers Book. Details of when to use this booklet are given in the teaching notes.
