Growth Dynamics of Conifer Tree Rings : Images of Past and Future Environments

Each tree ring contains an image of the time when the ring formed, projected onto the ring's size, structure, and composition. Tree rings thus are natural archives of past environments, and contain records of past climate. While dendrochronologists have investigated the impact of climate on tree-ring growth by empirical–statistical methods, this volume presents a process-based model complementing previous approaches. Basic ideas concerning the biology of tree-ring growth and its control by environmental factors are treated, especially for conifers. The use of the model is illustrated by means of several examples from widely differing environments, and possible future directions for model development and application are discussed. The volume provides an improved mechanistic basis for the interpretation of tree rings as records of past climate. It advances process understanding of the large-scale environmental control of wood growth. As forests are the main carbon sink on land, the results are of great importance for all global change studies.

Group rights as human rights : A liberal approach to multiculturalism

Liberal theories have long insisted that cultural diversity in democratic societies can be accommodated through classical liberal tools, in particular through individual rights, and they have often rejected the claims of cultural minorities for group rights as illiberal. Group Rights as Human Rights argues that such a rejection is misguided. Based on a thorough analysis of the concept of group rights, it proposes to overcome the dominant dichotomy between "individual" human rights and "collective" group rights by recognizing that group rights also serve individual interests.

Group Coordination and Cooperative Control

Group coordination and cooperative control are topics currently receiving a lot of interest. Coordinating the motion of a group of relatively simple and inexpensive agents can cover a larger operational area and achieve complex tasks exceeding the abilities of a single agent. This enables applications such as teams of robots for de-mining operations, aerospace formation flying for survey, fleets of AUVs for oceanographic mapping, and ships doing coordinated towing operations. This volume contains the contributions of the workshop. The book covers a wide range of subjects within the area of group coordination and cooperative control, and forms a valuable and up-to-date text on the newer trends in group coordination and cooperative control.

Groundwater Geophysics : A Tool for Hydrogeology

Geophysical techniques can map the underground conditions apart from boreholes. The use of these methods for hydrogeological applications is demonstrated for mapping of porous and structural aquifers, determination of groundwater quality (mineralization), assessment of hydraulic properties, determination of aquifer vulnerability and mapping of contaminated sites. Additionally, a description of geophysical techniques used for groundwater studies is given including seismics, resistivity methods, magnetics, ground penetrating radar and NMR (nuclear magnetic resonance).

Groundwater and Ecosystems

Groundwater Dependent Ecosystems (GDEs) frequently exhibit rich biological diversity and can provide enormous economic wealth. In recent years, GDEs in many industrialized countries have shown signs of serious degradation, primarily the result of groundwater abstraction and pollution. Many such systems, including a number of well documented cases in Eastern Europe, are no longer sustainable. As a consequence, the conservation and sustainable management of GDEs has emerged as one of the most urgent environmental research priorities of our time. A large percentage of the world’s population lives in cities and either depends on, or is affected in some way, by groundwater. Moreover, groundwater has become a very important and complex issue that attracts the interest of many diverse stakeholders. Many problems related to groundwater and ecosystems are shared by countries throughout the world and there is growing recognition that much can be gained by co-operation on an international scale.

Greens Functions in Quantum Physics

The main part of this book is devoted to the simplest kind of Green's functions, namely the solutions of linear differential equations with a -function source. It is shown that these familiar Green's functions are a powerful tool for obtaining relatively simple and general solutions of basic problems such as scattering and bound-level information. The bound-level treatment gives a clear physical understanding of "difficult" questions such as superconductivity, the Kondo effect, and, to a lesser degree, disorder-induced localization. The more advanced subject of many-body Green's functions is presented in the last part of the book.

Greening the Supply Chain

Since the Rio summit in 1992, the paradigm of corporate environmental responsibility has gradually and consistently extended beyond complying with increasingly stringent environmental regulation and taking up the proactive initiatives of a few world-class companies. Research indicates that the business and financial performance of companies may depend directly on socially and environmentally responsible business practices. Many world-class companies now realize that customers and other stakeholders do not distinguish between a company and its suppliers. As a result, greening the supply chain is an innovative idea which is fast gaining attention in the industry.

Green Function Theory of Chemisorption

The book provides an introduction to the Green-Function (GF) theory of chemisorption. It is self-contained, and requires only a basic knowledge of quantum mechanics and solid-state physics. The GF approach lends itself well to the pedagogically desirable modellistic treatment of the subject. Throughout each chapter, step-by-step details are provided by which the calculations are performed, so that readers are led from the simple to the more advanced aspects, in a straightforward manner. In this way, students gain confidence to read the current literature on their own.

Graphics of Large Datasets : Visualizing a Million

Graphics are great for exploring data, but how can they be used for looking at the large datasets that are commonplace to-day? This book shows how to look at ways of visualizing large datasets, whether large in numbers of cases or large in numbers of variables or large in both. Data visualization is useful for data cleaning, exploring data, identifying trends and clusters, spotting local patterns, evaluating modeling output, and presenting results. It is essential for exploratory data analysis and data mining. New approaches to graphics are needed to visualize the information in large datasets and most of the innovations described in this book are developments of standard graphics. There are considerable advantages in extending displays which are well-known and well-tried, both in understanding how best to make use of them in your work and in presenting results to others. It should also make the book readily accessible for readers who already have a little experience of drawing statistical graphics. All ideas are illustrated with displays from analyses of real datasets and the authors emphasize the importance of interpreting displays effectively. Graphics should be drawn to convey information and the book includes many insightful examples.
