This monograph presents computational techniques and numerical analysis to study conservation laws under uncertainty using the stochastic Galerkin formulation. With the continual growth of computer power, these methods are becoming increasingly popular as an alternative to more classical sampling-based techniques. The text takes advantage of stochastic Galerkin projections applied to the original conservation laws to produce a large system of modified partial differential equations, the solutions to which directly provide a full statistical characterization of the effect of uncertainties....

Die kinetische Theorie beschreibt Eigenschaften eines Gases bei der mikroskopischen Bewegung von Atomen und Molekulen, woraus alle stromungsrelevanten, makroskopischen Grossen ermittelt werden konnen. Sie ermoglicht ein tieferes Verstandnis fur die Ansatze der Kontinuumsmechanik und bietet die einzige Moglichkeit, Phanomene bei starkeren Abweichungen vom thermodynamischen Gleichgewicht zu erklaren und quantitativ zu bestimmen. Dieses Buch bietet eine verstandliche und gut gegliederte Einfuhrung in die molekulare Gasdynamik, es zeigt Losungsmoglichkeiten und Anwendungen aus...

The second, enlarged edition of this established reference integrates many new insights into wastewater hydraulics. This work serves as a reference for researchers but also is a basis for practicing engineers. It can be used as a text book for graduate students, although it has the characteristics of a reference book. It addresses mainly the sewer hydraulician but also general hydraulic engineers who have to tackle many a problem in daily life, and who will not always find an appropriate solution. Each chapter is introduced with a summary to outline the contents. To illustrate application...

Systems driven far from thermodynamic equilibrium can create dissipative structures through the spontaneous breaking of symmetries. A particularly fascinating feature of these pattern-forming systems is their tendency to produce spatially confined states. These localized wave packets can exist as propagating entities through space and/or time.

Various examples of such systems will be dealt with in this book, including localized states in fluids, chemical reactions on surfaces, neural networks, optical systems, granular systems, population models, and Bose-Einstein...

Unified Non-Local Theory of Transport Processess, 2^nd Edition provides a new theory of transport processes in gases, plasmas and liquids. It is shown that the well-known Boltzmann equation, which is the basis of the classical kinetic theory, is incorrect in the definite sense. Additional terms need to be added leading to a dramatic change in transport theory. The result is a strict theory of turbulence and the possibility to calculate turbulent flows from the first principles of physics.

• Fully revised and expanded edition, providing applications in quantum...
