Book Description
The main purpose of the eleven contributions to this volume is to reconsider and re-assess the role of cores and peripheries in shaping modern socio-technical systems. From this perspective they explore a terrain of highly complex systems mainly operating on the so-called Western model: Railways, telegraphs, motor vehicles and airports were, in fact, all born in classic cores areas in the West and then spread out into the peripheries. The approach in itself is not new, but this volume has managed to bring out interestingly innovative elements and viewpoints. The contributors are not content with the traditional definitions of peripheries and flows, but tend to put them to the test, revise them and eventually offer critiques. The result is a tempering of the monolithic and traditional concept of a one-way transfer. No longer, therefore, a simple and linear act of adoption, but a recourse to adaptation – changes in meaning, use and perception. The volume is a starting point for future explorations on the subject of science and technology studies and takes part in a wider discussion of globalisation, global and transnational history.

Book Description
Research centering on blood flow in the heart continues to hold an important position, especially since a better understanding of the subject may help reduce the incidence of coronary arterial disease and heart attacks. This book summarizes recent advances in the field; it is the product of fruitful cooperation among international scientists who met in Japan in May, 1990 to discuss the regulation of coronary blood flow.

Book Description
Despite generations of change and recent, rapid developments in gas dynamics and hypersonic theory, relevant literature has yet to catch up, so those in the field are generally forced to rely on dated monographs to make educated decisions that reflect present-day science. Written by preeminent Russian aerospace researcher Vladimir V. Lunev, Real Gas Flows with High Velocities reflects the most current concepts of high-velocity gas dynamics. For those in aviation and aerospace, this is a vital methodical revitalization and reassessment of real gas flows with regard to the physical and gasdynamic effects related to high-velocity flight, and, in particular, the entry of bodies into the atmosphere of Earth and other planets. Much more than just a manual on gas physics, this book: Analyzes fundamental challenges associated with super- and subsonic flight Describes the physical properties of gas mixtures and their associated high-temperature processes from the phenomenological standpoint Explores use of computational mathematics and equipment to simplify previously unsolvable problems of inviscid and viscous gas dynamics Explains why numerical methods remain inferior to analytical methods for creating a conceptual understanding of gas dynamic and other physical problems Avoiding older, cumbersome approximate methods, this reference outlines the general patterns and features of typical flows and how real gas affects them. Referencing simple, analytically treatable examples, similarity laws, and asymptotic analysis, the author omits superfluous explanation of reasoning. This valuable reference summarizes general theory of super- and subsonic flow and uses practical problems to develop a solid understanding of modern real-gas flows and high-velocity gas dynamics.

Book Description
This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.

Book Description
Optic flow provides all the information necessary to guide a walking human or a mobile robot to its target. Over the past 50 years, a body of research on optic flow spanning the disciplines of neurophysiology, psychophysics, experimental psychology, brain imaging and computational modelling has accumulated. Today, when we survey the field, we find independent lines of research have now converged and many arguments have been resolved; simultaneously the underpinning assumptions of flow theory are being questioned and alternative accounts of the visual guidance of locomotion proposed. At this critical juncture, this volume offers a timely review of what has been learnt and pointers to where the field is going.

Book Description
All biological systems with vision move about their environments and successfully perform many tasks. The same capabilities are needed in the world of robots. To that end, recent results in empirical fields that study insects and primates, as well as in theoretical and applied disciplines that design robots, have uncovered a number of the principles of navigation. To offer a unifying approach to the situation, this book brings together ideas from zoology, psychology, neurobiology, mathematics, geometry, computer science, and engineering. It contains theoretical developments that will be essential in future research on the topic -- especially new representations of space with less complexity than Euclidean representations possess. These representations allow biological and artificial systems to compute from images in order to successfully deal with their environments. In this book, the barriers between different disciplines have been smoothed and the workings of vision systems of biological organisms are made clear in computational terms to computer scientists and engineers. At the same time, fundamental principles arising from computational considerations are made clear both to empirical scientists and engineers. Empiricists can generate a number of hypotheses that they could then study through various experiments. Engineers can gain insight for designing robotic systems that perceive aspects of their environment. For the first time, readers will find: * the insect vision system presented in a way that can be understood by computational scientists working in computer vision and engineering; * three complete, working robotic navigation systems presented with all the issues related to their design analyzed in detail; * the beginning of a computational theory of direct perception, as advocated by Gibson, presented in detail with applications for a variety of problems; and * the idea that vision systems could compute space representations different from perfect metric descriptions -- and be used in robotic tasks -- advanced for both artificial and biological systems.
