Hypoelliptic estimates and spectral theory for Fokker-Planck operators and witten Laplacians
There has recently been a renewal of interest in Fokker-Planck operators, motivated by problems in statistical physics, in kinetic equations and differential geometry. Compared to more standard problems in the spectral theory of partial differential operators, those operators are not self-adjoint and only hypoelliptic. The aim of the analysis is to give, as generally as possible, an accurate qualitative and quantitative description of the exponential return to the thermodynamical equilibrium. While exploring and improving recent results in this direction this volume proposes a review of known techniques on: the hypoellipticity of polynomial of vector fields and its global counterpart; the global Weyl-Hörmander pseudo-differential calculus, the spectral theory of non-self-adjoint operators, the semi-classical analysis of Schrödinger-type operators.

The field is currently in interaction with a variety of scientific domains, including fluid dynamics, physics, electromagnetism, chemistry, biology, road and network traffic, and engineering. Many of these papers present new effective numerical methods and their application in various contexts.
Hydropower Economics
HYDROPOWER ECONOMICS examines sustainable alternate energy sources beginning with modeling hydropower and extending the model to include thermal power and wind power. The book will use various econometric measures, equilibrium metrics, OR methods, and DEA/productivity analyses to analyze and model the optimal use of these alternate energy sources. Because these problems are dynamic in nature, dynamic methods are used to model the problems. The book derives results on the allocation of the amounts of alternate sources of energy (water, thermal, and wind) required to produce electricity at acceptable levels over time. Graphic illustrations of the analytical and mathematical modeling used to reach research conclusions are used throughout the book.

Hybrid Intelligent Systems : Analysis and Design
The objective of this edited volume is to offer a general view at the recent conceptual developments of Soft Computing (SC) regarded as a general methodology supporting the design of hybrid systems along with their diversified applications to modeling, simulation and control of non-linear dynamical systems. As of now, SC methodologies embrace neural networks, fuzzy logic, genetic algorithms and chaos theory. Each of these methodologies exhibits well delineated advantages and disadvantages. Interestingly, they have been found useful in solving a broad range of problems. However, many real-world complex problems require a prudent, carefully orchestrated integration of several of these methodologies to fully achieve the required efficiency, accuracy, and interpretability of the solutions. In this edited volume, an overview of SC methodologies, and their applications to modeling, simulation and control, will be given in an introductory paper by the Editors. Then, detailed methods for integrating the different SC methodologies in solving real-world problems will be given in the papers by the other authors in the book. The edited volume will cover a wide spectrum of applications including areas such as: robotic dynamic systems, non-linear plants, manufacturing systems, and time series prediction.

Human Exploitation and Biodiversity Conservation
The sustainable use of biodiversity is one of the three key objectives of the 1992 "Convention on Biological Diversity". To achieve this, sound conservation practice has to be recognized as beneficial and implemented by all who access, or use it – from subsistence farmers to skiers and pharmaceutical bioprospectors. At the same time, indigenous peoples necessarily utilize enormous numbers of plants, fungi, and fish, particularly for foods and medicines. This book gathers together a wide range of contributions addressing diverse aspects of front-line human involvement in biodiversity exploitation and conservation. Its scope is broad, the organisms explored ranging from birds, invertebrates and mammals – both terrestrial and aquatic – to crops and medicinal plants. Meanwhile, the issues addressed include land use changes, the importance of gardens, hedges and green lanes, housing developments, hunting, invasive species, local community involvement, sacred groves, socioeconomic factors and trade.
Human Ecology : Biocultural Adaptations in Human Communities
Beginning with resource use and food procurement behaviour, the text examines major subsistence modes, the circumstances and dynamics of large-scale subsistence change, the effect of social differentiation on resource use and the effects of subsistence behaviour on population development and regulation.
How does the Galaxy Work? : A Galactic Tertulia with Don Cox and Ron Reynolds
Presents a multi-disciplinary approach to the physical mechanisms which structure the shape, evolution and fate of the Galaxy. It contains 4 panel sessions (the recording transcripts of the galactic 'tertulias'), an introductory historical overview on the Galaxy research, 17 reviews, and the proceedings of more than 50 oral and poster contributions. This book is not a new edition of a previous volume but it is in some way related to the book "The Formation of the Milky Way" (1995; Cambridge University Press), which contains the proceedings of the first IAA-IAC-University of Pisa meeting, held in Granada ten years ago, on the formation of the Milky Way, (see Shore's introduction). Where many other books focus their attention on singular galactic components or specific driving forces, this title provides a wide overview on the gaseous and stellar components and on the physical mechanisms which maintain the dynamical equilibrium of such a complex system as the Galaxy. The book, intended for graduate students and researchers, provides a valuable overview on the different physical mechanisms which drive the galactic gas-stars feedback.
Housing Market Dynamics in Africa
Utilizes new data to thoroughly analyze the main factors currently shaping the African housing market. Some of these factors include the supply and demand for housing finance, land tenure security issues, construction cost conundrum, infrastructure provision, and low-cost housing alternatives. Through detailed analysis, the authors investigate the political economy surrounding the continent’s housing market and the constraints that behind-the-scenes policy makers need to address in their attempts to provide affordable housing for the majority in need. With Africa’s urban population growing rapidly, this study highlights how broad demographic shifts and rapid urbanization are placing enormous pressure on the limited infrastructure in many cities and stretching the economic and social fabric of municipalities to their breaking point. But beyond providing a snapshot of the present conditions of the African housing market, the book offers recommendations and actionable measures for policy makers and other stakeholders on how best to provide affordable housing and alleviate Africa’s housing deficit.
Housing Estates in Europe : Poverty, Ethnic Segregation and Policy Challenges
Explores the formation and socio-spatial trajectories of large housing estates in Europe. Are these estates clustered or scattered? Which social groups originally had access to residential space in housing estates? What is the size, scale and geography of housing estates, their architectural and built environment composition, services and neighbourhood amenities, and metropolitan connectivity? How do housing estates contribute to the urban mosaic of neighborhoods by ethnic and socio-economic status? What types of policies and planning initiatives have been implemented in order to prevent the social downgrading of housing estates?The collection of chapters in this book addresses these questions from a new perspective previously unexplored in scholarly literature. The social aspects of housing estates are thoroughly investigated (including socio-demographic and economic characteristics of current and past inhabitants; ethnicity and segregation patterns; population dynamics; etc.), and the physical composition of housing estates is described in significant detail (including building materials; building form; architectural and landscape design; built environment characteristics; etc.).
