Available in PDF, EPUB and Kindle. Book excerpt: Coherent motions are understood to play an important role in enhancing the momentum transport of turbulent wall bounded shear flows, but determining whether or not a coherent motion is present in a given volume of space at a particular time is still a difficult task. Although most detection schemes were developed for use within a specific region above the wall, most are ultimately used throughout the entire boundary layer. Three different probe based algorithms and three different visual detection schemes are applied to combined flow visualization and spanwise vorticity probe data taken in the near wall region and at y/delta of 0.8. Several new performance parameters have been developed, and they are calculated along with most of the commonly used evaluation parameters as functions of detection threshold and Reynolds number or y+. The one to one correspondence between probe based detections and visual detections is also evaluated using two parameters already in common use and a new parameter, P(T, t), which is based on the number of event overlaps as a function of time during an event inner, outer, and mixed variables are used whenever appropriate to scale all results, but only two Reynolds number independent curves are found which describe the outer region response of any detection algorithm as a function of threshold.

Book Synopsis Perceptual Coherence by : Stephen Handel
Download or read book Perceptual Coherence written by Stephen Handel and published by Oxford University Press. This book was released on 2006-05-04 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: The job of any sensory system is to create objects in the world out of the incoming proximal stimulus energy. The energy is neutral; it does not specify the objects itself. Thus, sensory systems must abstract the energy that does specify objects and differentiate it from the noise energy. The perceptual variables that specify objects for both listening and looking become those of contrast and correlated change across space and time, so that perceiving occurs at several spatial and temporal scales in parallel. Given that the perceptual goals and perceptual variables are equivalent, the rules of perceiving will be the same for all senses. The goal of this book is to describe these conceptual similarities and differences between hearing and seeing. Although it is mathematical and conceptually analytical, the book does not make explicit use of advanced mathematical concepts. Each chapter combines information on hearing and seeing, and gives a detailed treatment of a small number of topics. The first three chapters present introductory information, including properties of auditory and visual worlds, how receptive fields are organized to pick out those properties, and whether the receptive fields are optimized to pick up the structure of the sensory world. Each subsequent chapter considers one type of perceptual element: texture, motion, contrast and noise, color, timbre, and object segmentation. Each type of perceptual situation is described as a problem of discovering the correlated energy, and the research presented focuses on how humans manage to perceive given the complicated set of skills required. This book is intended for use in upper-division undergraduate courses in perception and sensation, cognitive psychology, and neuroscience. It will fill the slot between textbooks that cover perception and sensory physiology and neuroscience, and more advanced monographs that cover one sense or topic in detail.

Book Synopsis Neuronal Information Processing, From Biological Data To Modelling And Application by : P Combe
Download or read book Neuronal Information Processing, From Biological Data To Modelling And Application written by P Combe and published by World Scientific. This book was released on 1999-05-31 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent developments in the neurosciences have considerably modified our knowledge of both the operating modes of neurons and information processing in the cortex. Multi-unit recordings have enabled temporal correlations to be detected, within temporal windows of the order of 1ms. Oscillations corresponding to a quasi-periodic spike-giving, synchronized over several visual cortical areas, have been observed in anaesthesized cats and monkeys. Recent studies have also focused on the role played by the dendritic arborization.These developments have led to considerable interest in a coding scheme which relies on precise spatio-temporal patterns from both the theoretical and experimental points of view. This prompts us to look into new models for information processing which will proceed, for example, from a synchronous detection of correlated spike giving, and is particularly robust against noise. Such models could bring about original technical applications for information processing and control.Further developments in this field may be of major importance for our understanding of the basic mechanisms of perception and cognition. They could also lead to new concepts in applications directed towards artificial perception and pattern recognition. Up to now, artificial systems for pattern recognition are far from reaching the standards of human vision. Systems based on a temporal coding by spikes may now be expected to bring about major improvements in this field.This book covers the lectures delivered at a summer school on neuronal information processing. It includes information on all the above-mentioned developments, and also provides the reader with the state-of-the-art in every relevant field, including the neurosciences, physics, mathematics, and information and control theory.

Book Synopsis Optical Coherence Tomography in Cardiovascular Research by : Evelyn Regar
Download or read book Optical Coherence Tomography in Cardiovascular Research written by Evelyn Regar and published by CRC Press. This book was released on 2007-03-06 with total page 1112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Given that for centuries, the standard tool to understand diseases in tissues was the microscope and that its major limitation was that only excised tissue could be used, recent technology now permits the examination of diseased tissue in vivo. Optical coherence tomography (OCT) has promising potential when applied to coronary artery disease. OCT has the capability to identify coronary plaque and to distinguish between plaques that are stable and unstable. If the plaques are stable then OCT can direct percutaneous intervention (angioplasty or stenting). Optical coherence tomography is a light-based imaging technology that allows for very high resolution imaging in biological tissues. It has been first applied in ophthalmology, where it soon became the golden standard for the assessment of (epi-) retinal processes. The unique imaging capabilities have raised the interest of researchers and clinicians in the field of cardiovascular disease, since OCT offers unique possibilities to study atherosclerosis pathophysiology in vivo. With over 1.1M Americans having a heart attack this year because of unstable plaque rupture, OCT may have an increasingly important role in the early diagnosis of coronary artery disease. This unique publication offers the reader the basic background to OCT and its role in the diagnosis and management of coronary artery disease. The Handbook of Optical Coherence Tomography in Cardiovascular Research introduces the cardiovascular application of this technology. Clinicians, biologists, engineers and physicist are discussing different aspects of cardiovascular OCT application in a multidisciplinary approach. The handbook offers the readership a concise overview on the current state of the art of vascular OCT imaging and sheds light on a variety of exciting new developments. The physics, technical principles of OCT and its application in a broad spectrum of cardiovascular research areas are summarized by highly recognized specialists. The potential of OCT in peripheral and coronary arteries and in developmental cardiology are described. Each research area is introduced by a clinical expert in the field followed by discussion of different aspects from an engineering, biomedical and clinical perspective. Specifically, the current capabilities for plaque characterization, detection of vulnerable plaque, guidance of interventional procedures, Doppler-assessment, and molecular contrast imaging are being described. The Handbook of Optical Coherence Tomography in Cardiovascular Research targets researchers and clinicians involved in the field of atherosclerosis. The summary of basic physics, engineering solutions, pre-clinical and clinical application covers all relevant aspects and will be a valuable reference source.
