Large Eddy Simulation (LES) is a high-fidelity approach to the numerical simulation of turbulent flows. Recent developments have shown LES to be able to predict aerodynamic noise generation and propagation as well as the turbulent flow, by means of either a hybrid or a direct approach.

This book is based on the results of two French/German research groups working on LES simulations in complex geometries and noise generation in turbulent flows. The results provide insights into modern prediction approaches for turbulent flows and noise generation mechanisms as well as their use for novel noise reduction concepts.

By covering theory, design, and fabrication of nanostructured superconducting materials, this monograph is an invaluable resource for research and development. Examples are energy saving solutions, healthcare, and communication technologies. Key ingredients are nanopatterned materials which help to improve the superconducting critical parameters and performance of superconducting devices, and lead to novel functionalities.

Das Buch untersucht die Phanomene Bubbles und Excess Volatility und geht insbesondere der Frage nach, ob beide auch auf dem deutschen Aktienmarkt nachweisbar sind. Der hierbei verwendete Datensatz reicht bis in das Jahr 1994 hinein."

Seminar paper from the year 2011 in the subject Geography / Earth Science - Economic Geography, grade: 1,3, University of Cologne (Wirtschafts- und Sozialgeographisches Institut), course: The Economic Geography of the European Union, language: English, abstract: In our globalized world trade fairs are important events for firms to communicate and/or sell their products and services to a global audience. But besides this original aim of trade fairs, scientists go further and focus on the effects, which these temporary and spatial accumulations of professionals from the same or equal industries might have. According to that, a particular focus lies on inter-organizational learning processes, like they can be found in clusters. Thus, the central question of this report derives, whether in the European context trade fairs can be seen as temporary clusters, which would imply that trade fairs became central nodes connecting global economy. This issue is important, since both participating in trade fairs and searching for adequate interaction partners are costly and time intensive processes. If trade fairs provided equal benefits as temporary clusters, organizing and participating entities would expend more effort on planning and conducting the time before, during and after the trade fair. Apparently, benefiting from new knowledge pools is at least an important aspect in times of increasing innovation velocity. Finding a clear answer for the problem is not trivial, since the majority of available literature focuses on trade fairs in the context of a communication instrument in firm's marketing mix. Furthermore there are difficulties to maintain a particular focus on Europe, since globalized world economy meets on international flagship trade fairs. Another aspect is the difficulty of measuring qualitative and quantifiable effects of spatial proximity in clusters, which additionally could be implemented to compare different forms of temporary clusters.

Diploma Thesis from the year 2012 in the subject Communications - Media Economics, Media Management, grade: 1,3, University of Cologne (Seminar fur Allgemeine BWL, Medien- und Technologiemanagement), course: Medienmanagement, language: English, abstract: This thesis considers the influence of digital distribution on the independent music artists' position in the value chain with respect to rights, costs, and market potential from the perspective of an economic analysis. It begins by delineating the relevant terms and providing a research background about the digital distribution of independent music artists. Ongoing, a new analytical framework is introduced in order to guide the economic analyses from rights and costs to the market potential, whereas direct and indirect distribution are compared from the independent music artists' point of view. It is found that digital distribution encourages independent music artists to enter the music market without the necessity of a major label. Furthermore, digital distribution seems to be an attractive way for unpopular artists to increase their awareness regardless likely copyright infringements.
