Classical Field Theory - Florian Scheck - Bog - Springer-Verlag Berlin and Heidelberg GmbH & Co. KG - Plusbog.dk

Classical Field Theory - Florian Scheck - Bog - Springer-Verlag Berlin and Heidelberg GmbH & Co. KG - Plusbog.dk

The book describes Maxwell''s equations first in their integral, directly testable form, then moves on to their local formulation. The first two chapters cover all essential properties of Maxwell''s equations, including their symmetries and their covariance in a modern notation. Chapter 3 is devoted to Maxwell theory as a classical field theory and to solutions of the wave equation. Chapter 4 deals with important applications of Maxwell theory. It includes topical subjects such as metamaterials with negative refraction index and solutions of Helmholtz'' equation in paraxial approximation relevant for the description of laser beams. Chapter 5 describes non-Abelian gauge theories from a classical, geometric point of view, in analogy to Maxwell theory as a prototype, and culminates in an application to the U(2) theory relevant for electroweak interactions. The last chapter 6 gives a concise summary of semi-Riemannian geometry as the framework for the classical field theory of gravitation. The chapter concludes with a discussion of the Schwarzschild solution of Einstein''s equations and the classical tests of general relativity (perihelion precession of Mercury, and light deflection by the sun). ------ Textbook features: detailed figures, worked examples, problems and solutions, boxed inserts, highlighted special topics, highlighted important math etc., helpful summaries, appendix, index.

Be Organoberyllium Compounds - Hubert Schmidbaur - Bog - Springer-Verlag Berlin and Heidelberg GmbH & Co. KG - Plusbog.dk

Be Organoberyllium Compounds - Hubert Schmidbaur - Bog - Springer-Verlag Berlin and Heidelberg GmbH & Co. KG - Plusbog.dk

The present volume describes organoberyllium compounds containing at least one berylli­ um-carbon bond, except the beryllium carbides and cyanides. It covers the literature com­ pletely to the end of 1986 and includes most of the references up to mid-1987. This Gmelin volume is different from all other volumes of the series on organometallic compounds in that it is dedicated to an area of research which has virtually come to a complete standstill. Organoberyllium chemistry has never been a very popular field, and only few workers have contributed to its slow growth, as is seen by the relatively small number of publications in the field. This very modest development became stagnant in the early 1970''s and was followed by a rapid decline. This exceptional fate of a branch of organometallic chemistry is only partly due to the very limited number of potential application~ of beryllium and its compounds. The compounds of this element are, in principle, at least as interesting and intriguing to scientists as those of other metals in the Periodic Table. No doubt the main reason for the apparent ban of all experimental organoberyllium chemistry is to be found in the established, and alleged, hazardous properties of beryllium compounds. Although similar hazards have been established for other organometallics where active research is still in process, e. g. , mercury and lead, these observations were absolutely lethaI for organoberyllium research.

Simulation-based Optimization of Energy Efficiency in Production - Anna Carina Roemer - Bog - Springer-Verlag Berlin and Heidelberg GmbH & Co. KG -

Simulation-based Optimization of Energy Efficiency in Production - Anna Carina Roemer - Bog - Springer-Verlag Berlin and Heidelberg GmbH & Co. KG -

The importance of the energy and commodity markets has steadily increased since the first oil crisis. The sustained use of energy and other resources has become a basic requirement for a company to competitively perform on the market. The modeling, analysis and assessment of dynamic production processes is often performed using simulation software. While existing approaches mainly focus on the consideration of resource consumption variables based on metrologically collected data on operating states, the aim of this work is to depict the energy consumption of production plants through the utilization of a continuous simulation approach in combination with a discrete approach for the modeling of material flows and supporting logistic processes. The complex interactions between the material flow and the energy usage in production can thus be simulated closer to reality, especially the depiction of energy consumption peaks becomes possible. An essential step towards reducing energy consumption in production is the optimization of the energy use of non-value-adding production phases.

Renewable Hydrogen - Matthieu Jaunatre - Bog - Springer-Verlag Berlin and Heidelberg GmbH & Co. KG - Plusbog.dk

Renewable Hydrogen - Matthieu Jaunatre - Bog - Springer-Verlag Berlin and Heidelberg GmbH & Co. KG - Plusbog.dk

Hydrogen has recently become a popular topic and is often described as the missing link to a successful green energy transition. However, hydrogen can only contribute to a carbon-free future if it is produced from renewable energy. The ability to produce renewable hydrogen is linked to the renewable energy production capacity, which is itself conditioned by the underpinning renewable energy policies. This publication offers a review and an analysis of the renewable energy and hydrogen policies of five countries of the APAC markets: Australia, China, Japan, South-Korea and Taiwan. The review is complemented by interviews of renewable energy policy experts, renewable energy project developers and potential renewable hydrogen off-takers. Altogether, the policies analysis and experts'' inputs provide a comprehensive overview of the status, drivers, limitations, and recommendations for the use of renewable hydrogen as a solution for deep decarbonization. Finally, the author proposes a method to assess the potential of renewable hydrogen to decarbonize hard-to-abate industries (ammonia, methanol, oil refining and steel manufacturing) based on existing renewable energy policies.

Advances in Markov-Switching Models - - Bog - Springer-Verlag Berlin and Heidelberg GmbH & Co. KG - Plusbog.dk

Advances in Markov-Switching Models - - Bog - Springer-Verlag Berlin and Heidelberg GmbH & Co. KG - Plusbog.dk

This book is a collection of state-of-the-art papers on the properties of business cycles and financial analysis. The individual contributions cover new advances in Markov-switching models with applications to business cycle research and finance. The introduction surveys the existing methods and new results of the last decade. Individual chapters study features of the U. S. and European business cycles with particular focus on the role of monetary policy, oil shocks and co­ movements among key variables. The short-run versus long-run consequences of an economic recession are also discussed. Another area that is featured is an extensive analysis of currency crises and the possibility of bubbles or fads in stock prices. A concluding chapter offers useful new results on testing for this kind of regime-switching behaviour. Overall, the book provides a state-of-the-art over­ view of new directions in methods and results for estimation and inference based on the use of Markov-switching time-series analysis. A special feature of the book is that it includes an illustration of a wide range of applications based on a common methodology. It is expected that the theme of the book will be of particular interest to the macroeconomics readers as well as econometrics professionals, scholars and graduate students. We wish to express our gratitude to the authors for their strong contributions and the reviewers for their assistance and careful attention to detail in their reports.
