Observing our Universe and its evolution with ever increasing sensitivity from ground-based or space-borne telescopes is posing great challenges to Fundamental Physics and Astronomy. The remnant cosmic microwave background, as beautifully measured by successive space missions COBE, WMAP, and now PLANCK, provides a unique probe of the very early stages of our Universe. The red-shift of atomic lines in distant galaxies, the dynamics of pulsars, the large scale structure of galaxies, and black holes are a few manifestations of the theory of General Relativity. Yet, today, we understand only 4% of the mass of our Universe, the rest being called dark energy and dark matter, both of unknown origin! A second family of space missions is currently emerging; rather than designing ever more re nedobservationalinstruments,physicistsandengineersseekalsotousethespaceenvironment to perform high-precision tests of the fundamental laws of physics. The technology required for such tests has become available only over the course of the last decades. Clocks of high accuracy are an example. They are based on advances in atomic and laser physics, such as cold atoms, enabling a new generation of highly sensitive quantum sensors for ground and space experiments. Two experiments in space have now tested Einstein's relativity theory: * Several decades ago, Gravity Probe A con rmed the accuracy of the gravitational red-shift ?5 according to general relativity to a level of 7x 10 [R. F. C. Vessot et al. , Test of Relativistic Gravitation with a Space-Borne Hydrogen Maser, Phys. Rev. Lett. 45, 2081-2084 (1980)].

The investigation of minor solar system bodies, such as comets and asteroids, using spacecraft requires an understanding of orbital motion in strongly perturbed environments. The solutions to a wide range of complex and challenging problems in this field are reviewed in this comprehensive and authoritative work.

A comprehensive textbook covering not only the ordinary theory of the deformation of solids, but also some topics not usually found in textbooks on the subject, such as thermal conduction and viscosity in solids.

This is a translation of A.I. Lurie's classical Russian textbook on analytical mechanics. Part of it is based on courses formerly held by the author. It offers a consummate exposition of the subject of analytical mechanics through a deep analysis of its most fundamental concepts. The book has served as a desk text for at least two generations of researchers working in those fields where the Soviet Union accomplished the greatest technological breakthrough of the 20th century - a race into space. Those and other related fields continue to be intensively explored since then, and the book clearly demonstrates how the fundamental concepts of mechanics work in the context of up-to-date engineering problems. This book will help researchers and graduate students to acquire a deeper insight into analytical mechanics.

In this book the modern theory of both regular and chaotic nonlinear oscillations is set out, primarily, as applied to mechanical problems. The material is presented in a nontraditional manner with emphasis on the new results of the theory obtained partially by the author, who is one of the leading experts in the area. Among the up-to-date topics are synchronization and chaotization of self-oscillatory systems and the influence of weak random vibrations on the modification of characteristics and behavior of nonlinear systems. One of the purposes of the book is to enable readers to gain a thorough understanding of this theory and to show that it can be very useful in engineering investigations. The primary audience for this book is researchers working with different oscillatory processes and students interested in a thorough study of the general laws and applications of the theory of nonlinear oscillations.

Why writing a book about a specialized task of the large topic of complex systems? And who will read it? The answer is simple: The fascination for a didactically valuable point of view, the elegance of a closed concept and the lack of a comprehensive disquisition.

The fascinating part is that field equations can have localized solutions exhibiting the typical characteristics of particles. Regarding the field equations this book focuses on, the field phenomenon of localized solutions can be described in the context of a particle formalism, which leads to a set of ordinary differential equations covering the time evolution of the position and the velocity of each particle. Moreover, starting from these particle dynamics and making the transition to many body systems, one considers typical phenomena of many body systems as shock waves and phase transitions, which themselves can be described as field phenomena. Such transitions between different level of modelling are well known from conservative systems, where localized solutions of quantum field theory lead to the mechanisms of elementary particle interaction and from this to field equations describing the properties of matter. However, in dissipative systems such transitions have not been considered yet, which is adjusted by the presented book. The elegance of a closed concept starts with the observation of self-organized current filaments in a semiconductor gas discharge system. These filaments move on random paths and exhibit certain particle features like scattering or the formation of bound states. Neither the reasons for the propagation of the filaments nor the laws of the interaction between the filaments can be registered by direct observations. Therefore a model is established, which is phenomenological in the first instance due to the complexity of the experimental system. This model allows to understand the existence of localized structures, their mechanisms of movement, and their interaction, at least, on a qualitative level. But this model is also the starting point for developing a data analysis method that enables the detection of movement and interaction mechanisms of the investigated localized solutions. The topic is rounded of by applying the data analysis to real experimental data and comparing the experimental observations to the predictions of the model.

A comprehensive publication covering the interesting topic of localized solutions in reaction diffusion systems in its width and its relation to the well known phenomena of spirals and patterns does not yet exist, and this is the third reason for writing this book. Although the book focuses on a specific experimental system the model equations are as simple as possible so that the discussed methods should be adaptable to a large class of systems showing particle-like structures.

Therefore, this book should attract not only the experienced scientist, who is interested in self-organization phenomena, but also the student, who would like to understand the investigation of a complex system on the basis of a continuous description.

The climate is changing as an unintended consequence of human industrialization and consumerism. Recently some scientists and engineers have suggested climate engineering-technological solutions that would intentionally change the climate to make it more hospitable. This approach focuses on large-scale technologies to alleviate the worst effects of anthropogenic climate change. This book considers the moral, philosophical, and religious questions raised by such proposals, bringing Christian theology and ethics into the conversation about climate engineering for the first time. The contributors have different views on whether climate engineering is morally acceptable and on what kinds of climate engineering are most promising and most dangerous, but all agree that religion has a vital role to play in the analysis and decisions called for on this vital issue. Calming the Storm presents diverse perspectives on some of the most vital questions raised by climate engineering: Who has the right to make decisions about such global technological efforts? What have we learned from the decisions that caused the climate to change that might shed light on efforts to reverse that change? What frameworks and metaphors are helpful in thinking about climate engineering, and which are counterproductive? What religious beliefs, practices, and rituals can help people to imagine and evaluate the prospect of engineering the climate?

This book presents to the design engineer the transducers and measurement techniques available, and evaluates their features and drawbacks. It is written for the instrument and systems designer, not the theoretician.

To this point, the field of lubrication has been conceptualized using several noncontiguous modes of operation - boundary, fluid-film, and dry and solid lubrication. Engineers and analysts have long had to deal with old evidence that many tribological devices, such as flat surface and centrally pivoted sliders, can act as viable bearings - contradicting basic hydrodynamic theory. Tribology of Interface Layers introduces a new concept wherein disparate modes are shown to actually be particular phases of a tribological continuum spanning a wide array of material lubricants. The author details these phenomena and presents a novel definition of lubricants as intermediate layers. Explores the phenomenon of continuum spectrum as applied to new powder lubrication technology The book illustrates that contrary to previous understanding, the various lubrication modes - from dry to hydrodynamic to powder lubrication - all overlap each other within a tribological spectral continuum. It also elucidates the fact that bearings, seals, dampers, and similar devices using submicron powder lubricants possess quasi-hydrodynamic characteristics akin to conventional fluid films. Similarly, powder films possess quasi-hydrodynamic features that enable them to act as conventional fluid film bearings. The field of tribology has traditionally been presented in terms of disparate regimes, but this method of classification lacked sufficient rigor. This volume explains that characterization and treatment of any one regime may require the simultaneous accounting of several different modalities that are present in a particular mode of operation. Based on experimental and theoretical work, this text shows how the interdependence of powder and hydrodynamic lubrication exemplifies that perpetuity in tribological processes. Author Hooshang Heshmat was on hand for a book signing at the 2010 STLE Meeting. Dr. Heshmat was the 2007 recipient of the Mayo D. Hersey Award, bestowed on an individual in recognition of distinguished and continuous contributions over a substantial period of time to the advancement of the science and engineering of tribology.

This book deals with blow-up of a solution to a system of PDEs that arise in practical situations. It begins with a relatively simple account of blow-up in systems of interaction-diffusion equations, then concentrates on mechanics. In particular it deals with the Euler equations, Navier--Stokes equations, models for glacier physics, Korteweg--de-Vries equations, and ferro-hydrodynamics. Blow-up is treated in Volterra equations, stressing how these equations arise in mechanics, e.g. in combustion theory. Further topics are chemotaxis in mathematical biology, change of type, from hyperbolic to elliptic, instability in soils, instability in sea ice dynamics, instability in pressure-dependent viscosity flow, and energy growth in parallel shear flows. It addresses graduate students and researchers in mechanics.

Originally published in 1968, this book was one of the first full-scale published studies of the principles of investment planning and of the structure of marginal costs in a public enterprise.

The volume that you have before you is the result of a growing realization that fluctuations in nonequilibrium systems playa much more important role than was 1 first believed. It has become clear that in nonequilibrium systems noise plays an active, one might even say a creative, role in processes involving self-organization, pattern formation, and coherence, as well as in biological information processing, energy transduction, and functionality. Now is not the time for a comprehensive summary of these new ideas, and I am certainly not the person to attempt such a thing. Rather, this short introductory essay (and the book as a whole) is an attempt to describe where we are at present and how the viewpoint that has evolved in the last decade or so differs from those of past decades. Fluctuations arise either because of the coupling of a particular system to an ex ternal unknown or "unknowable" system or because the particular description we are using is only a coarse-grained description which on some level is an approxima tion. We describe the unpredictable and random deviations from our deterministic equations of motion as noise or fluctuations. A nonequilibrium system is one in which there is a net flow of energy. There are, as I see it, four basic levels of sophistication, or paradigms, con cerning fluctuations in nature. At the lowest level of sophistication, there is an implicit assumption that noise is negligible: the deterministic paradigm."

Fundamentals of Robotics presents the basic concepts of robots to engineering and technology students and to practicing engineers who want to grasp the fundamentals in the growing field of robotics.

Gravity currents and intrusions are the ubiquitous phenomena where a fluid of one density flows horizontally into a fluid of a different density. For researchers and engineers, the ability to understand and predict these flow fields is essential in wide-ranging applications including those involved with atmospheric and ocean dynamics, the propagation of pollutants, and the dispersion of volcanic clouds. Although many new theories, experimental data, simulation results, and insights have surfaced recently, most of these developments remain scattered in journals and conference papers. A systematic and unified introduction to the field, which incorporates the new results and developments, is bound to facilitate the application of the available knowledge to both practical problems and further investigations. Written by a recognized authority active in recent developments in gravity current research, An Introduction to Gravity Currents and Intrusions provides an up-to-date, self-contained, and systematic introduction to the study, interpretation, and prediction of gravity current flows. The author uses a simple mathematical framework to provide an accessible and comprehensive introduction to the mathematical and physical aspects of this important topic. The text supplies researchers and practitioners with the foundation required to formulate problems, interpret experimental results and measurements data, obtain simple and insightful analytical estimates and solutions, and develop or implement numerical codes for related problems. The book also points out gaps of knowledge in the current understanding that require further research. This accessible reference requires only a basic background in fluid mechanics and applied mathematics, making it an ideal starting place for researchers and engineers new to the field. It can also serve as a textbook for upper-level undergraduate and graduate level courses in flu
