An Introduction to the Heisenberg Group and the Sub-Riemannian Isoperimetric Problem
This book provides an introduction to the basics of sub-Riemannian differential geometry and geometric analysis in the Heisenberg group, focusing primarily on the current state of knowledge regarding Pierre Pansu's celebrated 1982 conjecture regarding the sub-Riemannian isoperimetric profile.
An Archaeological Evolution
An Archaeological Evolution is a personal recounting of his life as it is played out among some of the most important debates and movements in archaeology starting in the 1960's up to the 21st century.This seminal volume will be of interest to archaeologists (both professional and academic), anthropologists, historians, and conservators in or studying the United States but also, wherever archaeology is taught and practiced.
Algebraic Methods for Nonlinear Control Systems
A self-contained introduction to algebraic control for nonlinear systems suitable for researchers and graduate students.The most popular treatment of control for nonlinear systems is from the viewpoint of differential geometry yet this approach proves not to be the most natural when considering problems like dynamic feedback and realization. Professors Conte, Moog and Perdon develop an alternative linear-algebraic strategy based on the use of vector spaces over suitable fields of nonlinear functions. This algebraic perspective is complementary to, and parallel in concept with, its more celebrated differential-geometric counterpart.Algebraic Methods for Nonlinear Control Systems describes a wide range of results, some of which can be derived using differential geometry but many of which cannot.
Air-Ice-Ocean Interaction : Turbulent Ocean Boundary Layer Exchange Processes
At a time when the polar regions are undergoing rapid and unprecedented change, understanding exchanges of momentum, heat and salt at the ice-ocean interface is critical for realistically predicting the future state of sea ice. By offering a measurement platform largely unaffected by surface waves, drifting sea ice provides a unique laboratory for studying aspects of geophysical boundary layer flows that are extremely difficult to measure elsewhere. This book draws on both extensive observations and theoretical principles to develop a concise description of the impact of stress, rotation, and buoyancy on the turbulence scales that control exchanges between the atmosphere and underlying ocean when sea ice is present. Several interesting and unique observational data sets are used to illustrate different aspects of ice-ocean interaction ranging from the impact of salt on melting in the Greenland Sea marginal ice zone, to how nonlinearities in the equation of state for seawater affect mixing in the Weddell Sea.
Agricultural Implications of the Fukushima Nuclear Accident : The First Three Years
Consists of various topics, including radioactivity inspection of food products; decontamination trials for rice and livestock production; the state of contamination in wild animals and birds, trees, mushrooms, and timber; the dynamics of radioactivity distribution in mountain and paddy fields; damage incurred by the forestry and fishery industries; and the change in consumers’ minds. The last chapter introduces a real-time radioisotope imaging system, the forefront technique to visualize actual movement of cesium in soil and in plants. This is the only book to provide systematic data about the actual change of radioactivity, and thus is of great value for all researchers who wish to understand the effect of radioactive fallout on agriculture.
Agricultural Implications of the Fukushima Nuclear Accident (III)
Reports on studies undertaken at contaminated sites such as farmland, forests, and marine and freshwater environments, with a particular focus on livestock, wild plants and mushrooms, crops, and marine products in those environments. It also provides additional data collected in the subsequent years to show how the radioactivity levels in agricultural products and their growing environments have changed with time and the route by which radioactive materials entered agricultural products as well as their movement between different components (e.g., soil, water, and trees) within an environmental system (e.g., forests). The book covers various topics, including radioactivity testing of food products; decontamination trials for rice and livestock production; the state of contamination in, trees, mushrooms, and timber; the dynamics of radioactivity distribution in paddy fields and upland forests; damage incurred by the forestry and fishery industries; and the change in consumers’ attitudes. Chapter 19 introduces a real-time radioisotope imaging system, a pioneering technique to visualize the movement of cesium in soil and in plants.
Ages, generations and the social contract : The demographic challenges facing the welfare state
Our societies are ageing. The Family is changing. Labour force behaviour is evolving. How is the organisation of family and collective solidarity adapting in this context of longer life spans, low fertility, and work that is simultaneously scarce and abundant? The welfare states are currently facing three main challenges: ensure satisfactory living conditions for the elderly without increasing the cost burden on the active population, reduce social inequality, and maintain equity between successive generations. In this book, researchers from different countries compare their experiences and offer contrasting views on the future of social protection. They consider the theoretical aspects of the intergenerational debate, relations between generations within the family, the living standards of elderly people, and the question of social time.
After Bourdieu : Influence, Critique, Elaboration
Intellectual origins & orientations We begin by providing an overview of Bourdieu’s life as a scholar and a public intellectual. The numerous obituaries and memorial tributes that have appeared following Bourdieu’s untimely death have revealed something of his life and career, but few have stressed the intersection of his social origins, career trajectory, and public intellectual life with the changing political and social context of France. This is precisely what David Swartz’s “In memoriam” attempts to accomplish. In it he emphasizes the coincidence of Bourdieu’s young and later adulthood with the period of decolonization, the May 1968 French university crisis, the opening up of France to privatization of many domains previously entrusted to the state (l’état providence), and, most threatening to post-World War II reforms, the emergence of globalization as the hegemonic structure of the 21st century.

Collectively, the chapters present a rich methodological spectrum, from narrative analysis to structural equation modelling.
Aerosol Optics : Light Absorption and Scattering by Particles in the Atmosphere
Provides a comprehensive review of available techniques for the remote sensing of aerosols. Although mostly satellite remote sensing is considered, ground-based techniques are also discussed.describes techniques for the determination of the column concentration of aerosol particles and their optical sizing using spaceborne optical instrumentation. The majority of the techniques described in this book use a so-called "library method". This method relies upon the precalculated top-of-atmosphere reflectances (TOAR) for vaious atmospheric aerosol types. The comparison of measured and calculated TOARS allows one to characterize the optically-equivalent aerosol state.
