Ernst Equation and Riemann Surfaces : Analytical and Numerical Methods
Exact solutions to Einstein`s equations have been useful for the understanding of general relativity in many respects. They have led to physical concepts as black holes and event horizons and helped to visualize interesting features of the theory. In addition they have been used to test the quality of various approximation methods and numerical codes. The most powerful solution generation methods are due to the theory of Integrable Systems. In the case of axisymmetric stationary spacetimes the Einstein equations are equivalent to the completely integrable Ernst equation. In this volume the solutions to the Ernst equation associated to Riemann surfaces are studied in detail and physical and mathematical aspects of this class are discussed both analytically and numerically.
Equilibrium Between Phases of Matter : Phenomenology and Thermodynamics
The phase behaviour of materials and their thermodynamic properties are a central subject in all fields of materials research. The first Volume of the work, meant for graduate students in chemistry, geology, physics, and metallurgy, and their engineering counterparts, is split up in three levels, such that from level to level the portion and importance of thermodynamics and mathematics are increased. In the ground level it is shown that the basic principles of phase equilibria can be understood without the use of thermodynamics – be it that the concept of chemical potential is introduced right from the beginning. The intermediate level is an introduction to thermodynamics; culminating in the Gibbs energy as the arbiter for equilibrium – demonstrated for systems where the phases in equilibrium are pure substances. In the third level the accent is on binary systems, where one or more phases are solutions of the components.

Entrepreneurial Strategy : Starting, Managing, and Scaling New Ventures
This book focuses on explaining differences amongst organizations regarding various attributes, forms, and outcomes. By focusing on the “how” of new venture creation and management to produce well-established organizations, the authors aim to increase our understanding of the antecedents of most management research assumptions. New ventures are the source of most newly created jobs generated in an economy, new industries and markets, innovative products and services, and new solutions to economic, social, and environmental problems. However, most management research assumes a well-established organization as the starting point of their theorizing.

Enhanced Living Environments : Algorithms, Architectures, Platforms, and Systems
Ambient Assisted Living (AAL) is an area of research based on Information and Communication Technologies (ICT), medical research, and sociological research. AAL is based on the notion that technology and science can provide improvements in the quality of life for people in their homes, and that it can reduce the financial burden on the budgets of the healthcare providers. The concept of Enhanced Living Environments (ELE) refers to the AAL area that is more related with ICT. Effective ELE solutions require appropriate ICT algorithms, architectures, platforms, and systems, having in view the advance of science in this area and the development of new and innovative solutions. The aim of this book is to become a state-of-the-art reference, discussing progress made, as well as prompting future directions on theories, practices, standards, and strategies related to the ELE area.
Engineering self-organising systems Vol. 3910 ; 3rd International Workshop, ESOA 2005, Utrecht, The Netherlands, July 25, 2005, Revised Selected Papers
This book contains recent work from a broad range of areas with the common theme of utilising self-organisation productively. As distributed information infrastructures continue to spread (such as the Internet, wireless and mobile systems), new challenges have arisen demanding robust and scalable solutions. In these new challenging environments the - signers and engineers of global applications and services can seldom rely on centralised control or management, high reliability of devices, or secure en- ronments. At the other end of the scale, ad-hoc sensor networks and ubiquitous computing devices are making it possible to embed millions of smart computing agents into the local environment.
Engaged Learning with Emerging Technologies
The major purpose of this book is to present and discuss current thinking, theories, conceptual frameworks, models and promising examples of engaged learning with emerging technologies. Contributions come from distinguished academics in the USA, Canada, the Netherlands, United Kingdom, Germany, Australia, New Zealand, China, Korea and Singapore. Following from a constructivist orientation, coupled with social cultural dimensions of learning, this volume documents how emerging learning technologies are appropriated into meaningful and engaged learning and instructional situations. The field of learning technologies is grounded on the theoretical constructs of the learning sciences and thus the chapters in this book balance between theory and practice and prepositions and solutions.
Energy in Africa : Challenges and Opportunities

Emerging States at Crossroads
This volume analyzes the economic, social, and political challenges that emerging states confront today. Notwithstanding the growing importance of the ‘emerging states’ in global affairs and governance, many problems requiring immediate solutions have emerged at home largely as a consequence of the rapid economic development and associated sociopolitical changes. The middle-income trap is a major economic challenge faced by emerging states. This volume regards interest coordination for technological upgrading as crucial to avoid the trap and examines how various emerging states are grappling with this challenge by fostering public-private cooperation, voluntary associations of market players, and/or social networks. Social disparity is another serious problem. This volume argues that the economic, social, and political problems are interwoven in the sense that the emerging states need to build political consensus in order to tackle the economic and social difficulties. Democratic institutions have not always been successful in this respect.
