Viscoelastic Subdiffusive Flows: Theory and Computation (Fluid Mechanics and Its Applications #138)
by Helen Wilson Sarthok Sircar Priyanka ShuklaThis book discusses the dynamical and rheological properties of high molecular weight entangled polymer melts, commonly known as viscoelastic subdiffusive fluids. Unlike dilute liquids, these materials exhibit molecular transport within a sublinear regime, meaning the timescale of diffusive transport is sublinear. The text emphasizes the potential of fractional calculus in modeling these fluids and introduces a novel fractional model to investigate regions of spatiotemporal instability in channel flows. At the microscale, the entanglement of polymer chains leads to localized, non-homogeneous regions with increased viscosity, which manifest as spatiotemporal macrostructures at the macroscale. To capture these macrostructures within the flow, direct numerical simulations are employed using a newly developed, physically realizable structure tensor, contributing to a deeper understanding of this complex class of fluids.
Viscoplastic Flow in Solids Produced by Shear Banding
by Ryszard B. PecherskiA complete overview of the topic of viscoplastic flow in metallic solids produced by shear banding This book presents novel ideas about inelastic deformation and failure of the material in a clear, concise manner. It exposes readers to information that will allow them to acquire the competence and ability to deal with up-to-date manufacturing and failure processes. It also portrays an interdisciplinary and revolutionary understanding of deformation processes in solids. Shear banding's typical mechanism becomes the active cause of viscoplastic flow and not the passive effect. Viscoplastic Flow in Metallic Solids Produced by Shear Banding begins with discussing the new physical model of multilevel hierarchy and evolution of micro-shear bands. It then covers the physical motivation and heuristic foundations of theoretical description concerning known results in the literature. It examines the difficulties of applying a direct multiscale integration scheme across the scales. It also presents an extension of the representative volume element (RVE) concept using the general theory of propagating the singular surfaces of the microscopic velocity field sweeping the RVE. It also reveals a new formulation of the description of the shear strain rate generated by the multilevel hierarchy of shear bands in the workflow integration approach, in which information from the simulation at different levels flows. This book: Presents fresh ideas about inelastic deformation and failure of materials Provides readers with the competence and ability to deal with up-to-date manufacturing and failure processes Sheds light on the interdisciplinary revolution in the recent understanding of deformation processes in solids Viscoplastic Flow in Metallic Solids Produced by Shear Banding will appeal to researchers studying physical foundations of inelastic deformation of materials and dealing with numerical simulations of manufacturing processes. It is also an excellent resource for graduate and postgraduate students of material science and mechanical engineering faculties.
Viscous Flows
by Ahmer MehmoodExact solution of Navier-Stokes equations is possible only for very simple flow situations such as unidirectional flows. Due to the nonlinear nature of these equations their analytic solutions are rare and the situation gets worse in the case of unsteady and multidimensional flow problems. In this book we report highly accurate and purely analytic solutions to some steady/unsteady multidimensional viscous flows over flat surface. Heat transfer analysis has also been carried out where the flat surface is considered as a stretching sheet. In each case the skin friction and the rate of heat transfer has been reported. The issue of cooling of stretching sheet in the presence of viscous dissipation has been discussed in detail. We have used homotopy analysis method to solve the governing nonlinear differential equations. The results are purely analytic and highly accurate. The accuracy of results has been proved by calculating the residual errors and (or) giving the comparison with the existing results. for unsteady flows it is worthy to mention here that our analytic solutions are uniformly valid for all time in the whole spatial domain.
Viscous Fluid Flow
by Tasos Papanastasiou Georgios Georgiou Andreas N. Alexandrou"With the appearance and fast evolution of high performance materials, mechanical, chemical and process engineers cannot perform effectively without fluid processing knowledge. The purpose of this book is to explore the systematic application of basic engineering principles to fluid flows that may occur in fluid processing and related activities.In Viscous Fluid Flow, the authors develop and rationalize the mathematics behind the study of fluid mechanics and examine the flows of Newtonian fluids. Although the material deals with Newtonian fluids, the concepts can be easily generalized to non-Newtonian fluid mechanics. The book contains many examples. Each chapter is accompanied by problems where the chapter theory can be applied to produce characteristic results.Fluid mechanics is a fundamental and essential element of advanced research, even for those working in different areas, because the principles, the equations, the analytical, computational and experimental means, and the purpose are common.
Visible Empire: Botanical Expeditions and Visual Culture in the Hispanic Enlightenment
by Daniela BleichmarBetween 1777 and 1816, botanical expeditions crisscrossed the vast Spanish empire in an ambitious project to survey the flora of much of the Americas, the Caribbean, and the Philippines. While these voyages produced written texts and compiled collections of specimens, they dedicated an overwhelming proportion of their resources and energy to the creation of visual materials. European and American naturalists and artists collaborated to manufacture a staggering total of more than 12,000 botanical illustrations. Yet these images have remained largely overlooked—until now. In this lavishly illustrated volume, Daniela Bleichmar gives this archive its due, finding in these botanical images a window into the worlds of Enlightenment science, visual culture, and empire. Through innovative interdisciplinary scholarship that bridges the histories of science, visual culture, and the Hispanic world, Bleichmar uses these images to trace two related histories: the little-known history of scientific expeditions in the Hispanic Enlightenment and the history of visual evidence in both science and administration in the early modern Spanish empire. As Bleichmar shows, in the Spanish empire visual epistemology operated not only in scientific contexts but also as part of an imperial apparatus that had a long-established tradition of deploying visual evidence for administrative purposes.

Visible Light Photocatalyzed Redox-Neutral Organic Reactions and Synthesis of Novel Metal-Organic Frameworks
by Basudev SahooThis unique thesis discusses the development of conceptually novel and synthetically valuable methods that use visible light photocatalysis. Each chapter addresses a different topic in the emerging field of photocatalysis, which has become an indispensable tool for organic synthesis. Photocatalysis employs environmentally harmless and abundant visible light in the presence of a photosensitizer, and as such offers an attractive alternative to harmful UV light in photo-mediated reactions. This book introduces the novel concept of merging gold catalysis with visible light photocatalysis in a dual catalytic fashion, which demonstrates their compatibility with each other for first time and has inspired the development of various reactions. Moreover, a novel trifluoromethylation method, which combines radical addition chemistry with a polar rearrangement to synthesize valuable fluorinated compounds, is presented, since compounds featuring fluorinated functionality are the subject of increasing attention in pharmaceutical, agrochemical and material research. It also develops an external photocatalyst-free photochemical method for the synthesis of valuable indolizine heterocycles, where the product mediates its own formation. Lastly, it describes the synthesis and characterization of two novel highly porous metal-organic frameworks (MOFs). The comprehensive text is rounded out with illustrations and color figures.

Vision Through the Atmosphere (Heritage)
by W.E.K. MiddletonIn recent years, the problem of seeing through the atmosphere has been given intensive and costly consideration in several quarters, but particularly in the Untied States and Great Britain. A problem which once concerned mainly the meteorologists has become of great importance in military tactics as well as in peacetime transportation. The present volume is the only full account in English of the physical, physiological, and psychological factors which lie at the basis of the calculation of the range of vision through the atmosphere. There is an extended chapter on instruments and one on the author's own theory of the colours of distant objects. The figures are from many sources althrough many of them have been drawn specially for this book. The bibliography contains 420 entries nearly all of which are directly referred to in the text.
Vision and Art
by Margaret S. Livingstone David Hubel<p>With the original release of Vision and Art in 2002, Harvard professor Margaret Livingstone successfully bridged the gap between science and art, exploring how great painters fool the brain: why Mona Lisa’s smile seems so mysterious, or Monet’s Poppy Field appears to sway. In the revised and expanded edition, Livingstone presents two new chapters of her latest observations, has substantially expanded other chapters, and updates the rest of the existing text with new insights gleaned from her ongoing research, bringing the book to the cutting edge in the field of neuroscience. <p>Accompanying Livingstone’s lively prose are many charts and diagrams that lucidly illustrate her points, as well as in-depth analyses of the phenomena found in major works of art. Be it the explanation of common optical illusions or the breakdown of techniques painters use to create those illusions, Vision and Art provides a wealth of information for artists, scholars, and scientists alike.</p>
Vision and Art with Two Eyes (Vision, Illusion and Perception #3)
by Nicholas WadeThis book celebrates binocular vision by presenting illustrations that require two eyes to see the effects of cooperation and competition between them. Pictures are flat but by printing them in different colours and viewing them through similarly coloured filters (included with the book) they are brought to life either in stereoscopic depth or in rivalry with one another. They are called anaglyphs and all those in the book display the ways in which the eyes interact. Thus, the reader is an integral element in the book and not all readers will see the same things. The history, science and art of binocular vision can be experienced in ways that are not usually available to us and with images made specifically for this book. The study of vision with two eyes was transformed by the invention of stereoscopes in the early 19th century. Anaglyphs are simple forms of stereoscopes that have three possible outcomes from viewing them – with each eye alone to see the monocular images, with both eyes to see them in stereoscopic depth or rivalry, or without the red/cyan glasses where they can have an appeal independent of the binocularity they encompass. Through the binocular pictures and the words that accompany them there will be an appreciation of just how remarkable the processes are that yield binocular singleness and depth. Moreover, the opportunities for expressing these processes are explored with many examples of truly binocular art.

Vision and Mind: Modeling Mental Functions
by Vadim D. GlezerThe usual method for studying mental processes entails taking words in linguistics -- or concepts in logic -- and establishing the connections and relationships between them. Thus, the traditional approach to semantic problems -- those of meaning and understanding -- is through language. Most researchers agree that thought and language are generated by deep-seated semantic structures determined by the structure of the brain. Until now, however, all attempts at constructing semantic models have been made on the basis of linguistic material alone, without taking brain structure into account. Analysis of these models shows them to be as inadequate as those based on the method of the black box. This book approaches the problem of the organization of higher psychological functions a different way -- by analyzing the functional organization of the neural structures that gradually form universal categories from "raw" sensory material. At the higher levels of the brain's operation, these universals correspond to the basic categories of thought and language. The visual system provides rewarding material for such an approach, both because it is relatively well researched and because it is the main source of sensory information in humans. With this in mind, this monograph examines the whole process of the transformation and description -- the coding of visual information. The most important aspect of this process is the transition from the description of visual space to the description of individual objects and the relationships between them. This transition is made possible by the existence in the visual system of various mechanisms that developed during evolution as a result of environmental influences. Written for a wide circle of investigators in disciplines associated with different aspects of the functioning of the brain -- physiologists and psychologists -- this book is also of importance to engineers and mathematicians working on the problems of artificial intelligence, and linguists and philosophers interested in the deep structures that form the universals of thought and language.
