Stochastic Interacting Particle Systems and Nonlinear Partial Differential Equations from Fluid Mechanics
Philipowski, Robert (2007)We derive stochastic particle approximations for two nonlinear partial differential equations from fluid mechanics: the porous medium equation and the three-dimensional Navier-Stokes equation. We associate interacting ... -
Stochastic many-particle systems far from equilibrium coupled to bulk reservoirs
Willmann, Richard Daniel (2004)In this work the influence of bulk reservoirs on lattice models for many-particle systems far from equilibrium is studied.<br /> A hydrodynamic equation is presented that allows to compute the steady state density profile ... -
Stochastic Parameterization: A Rigorous Approach to Stochastic Three-Dimensional Primitive Equations
Weniger, Michael (2014-04-02)The atmosphere is a strongly nonlinear and infinite-dimensional dynamical system acting on a multitude of different time and space scales. A possible problem of numerical weather prediction and climate modeling using ... -
Stochastic physical models for wind fields and precipitation extremes
Hewer, Rüdiger (2018-07-03)A major goal of this thesis is to introduce stochastic, physically consistent models for precipitation extremes based on the moisture budget. The moisture budget describes the moisture flux convergence and is essential for ... -
Stochastische Synchronisation und Desynchronisation gekoppelter und ungekoppelter selbsterhaltender Oszillatoren
Müller, Andy (2008)<p>In der vorliegenden Dissertation wird einerseits das der Intuition widersprechende Phänomen der Synchronisation selbsterhaltender Oszillatoren durch den Einfluss gemeinsamen externen Rauschens, die sogenannte stochastische ... -
Der Stoffwechsel der Sphingolipide: Einfluss von Substratanaloga der Dihydroceramid-Desaturase auf den Sphingolipidstoffwechsel humaner Keratinozyten und Untersuchungen zum Lipidstoffwechsel bei Spinocerebellärer Ataxie Typ 2
Brodesser, Susanne (2007)Die Dihydroceramid-4-Desaturase ist ein membrangebundenes Enzym höherer Eukaryonten, das auf der zytosolischen Seite des Endoplasmatischen Retikulums lokalisiert ist. Sie katalysiert mit der Einführung der 4,5-(<i>E</i>) ... -
Storage of Short Light Pulses in a Fiber-Based Atom-Cavity System
Macha, Tobias Nicolay (2019-05-16)In this work I theoretically investigate and experimentally realize the storage of short light-pulses in a fiber-based atom-cavity system. Our miniaturized optical resonator - with seven times the natural atomic linewidth ... -
Strahlenschädigung in Ultraschall-exponiertem Quarzglas
Negrini, Christine Maria (2008)<p>Strahlenschädigung in Materialien ist für Energiereiche Strahlung bisher nur unzureichend untersucht worden. Über hohe Teilchenenergien werden große Eindringtiefen in das Probenmaterial erreicht. Die produzierte ... -
Strahlpolarimetrie am CBELSA/TAPS Experiment
Kammer, Susanne (2010-03-18)Bei der Identifizierung von Nukleonresonanzen spielen Polarisationsobervablen eine entscheidene Rolle. Für die Photoproduktionsexperimente des CBELSA/TAPS-Aufbaus an der Beschleunigeranlage ELSA wurden im Rahmen dieser ... -
Strahlungsbegleitete π0-Photoproduktion am Proton
Schumann, Sven (2008)Diese Arbeit beschreibt ein Experiment zur strahlungsbegleiteten π<sup>0</sup>-Photoproduktion am Proton im Energiebereich der Δ-Resonanz, das in den Jahren 2004 und 2005 am Elektronenbeschleuniger MAMI (<b>Ma</b>inzer ... -
Strategies and Approaches for Exploiting the Value of Open Data
Attard, Judie (2017-05-15)Data is increasingly permeating into all dimensions of our society and has become an indispensable commodity that serves as a basis for many products and services. Traditional sectors, such as health, transport, retail, ... -
Strategies and Techniques for Federated Semantic Knowledge Retrieval and Integration
Collarana Vargas, Diego (2019-05-02)The vast amount of data shared on the Web requires effective and efficient techniques to retrieve and create machine usable knowledge out of it. The creation of integrated knowledge from the Web, especially knowledge about ... -
Strategies for a Semantified Uniform Access to Large and Heterogeneous Data Sources
Mami, Mohamed Nadjib (2021-02-18)The remarkable advances achieved in both research and development of Data Management as well as the prevalence of high-speed Internet and technology in the last few decades have caused unprecedented data avalanche. Large ... -
Strategies for Managing Linked Enterprise Data
Galkin, Mikhail (2019-02-12)Data, information and knowledge become key assets of our 21st century economy. As a result, data and knowledge management become key tasks with regard to sustainable development and business success. Often, knowledge is ... -
Strategies for the intelligent integration of genetic variance information in multiscale models of neurodegenerative diseases
