Fluid Flow and Heat Transfer in Cellular Solids
(2014)
To determine the characteristics and properties of cellular solids for an application, and to allow a systematic practical use by means of correlations and modelling approaches, we perform experimental investigations and ...
In-situ H2O removal via hydorphilic membranes during Fischer-Tropsch and other fuel-related synthesis reactions
(2011)
The general objective of this thesis was to explore the potential of in-situ H2O removal during fuel-related synthesis reactions with focus on in-situ H2O removal by hydrophilic membranes and by chemical reaction. It is ...
In-situ Visualisierung von Oberflächendeformationen aufgrund von Marangoni-Konvektion während der Filmtrocknung
(2014)
In the production of modern components, e.g. displays, complex substrates with e.g. conducting paths and pre-structuring are liquid coated and dried. The surfaces of such layers have to have a very well specified quality, ...
Incentives and Two-Sided Matching - Engineering Coordination Mechanisms for Social Clouds
(2014)
The Social Cloud framework leverages existing relationships between members of a social network for the exchange of resources. This thesis focuses on the design of coordination mechanisms to address two challenges in this ...
Indicator-based Sustainability Assessment of the German Energy System and its Transition
(2018)
The energy transition not only has an impact on technical infrastructures but also leads to socio-economic changes. To evaluate the sustainability aspects of the German Energiewende, the authors have developed a monitoring ...
Hochgenaue radarbasierte Abstandsmessung mit geführter Wellenausbreitung
(2016)
In this work, a new measurement approach for a radar-based high accuracy distance measurement with guided wave propagation is presented. The reached distance accuracy is in the single-digit range. The main influencing ...
Hochtemperaturaufladung von gasgetragenen Partikelsystemen
(2011)
Ziel der vorliegenden Arbeit war eine detaillierte Untersuchung der Mechanismen und Einflussfaktoren der Hochtemperaturaufladung gasgetragener Partikelsysteme. Dieses Ziel wurde durch Experimente, Modellbildung und Simulation ...
Homogenization and materials design of mechanical properties of textured materials based on zeroth-, first- and second-order bounds of linear behavior
(2018)
This work approaches the fields of homogenization and of materials design for the linear and nonlinear mechanical properties with prescribed properties-profile. The set of achievable properties is bounded by the zeroth-order ...
Homogenization of the Linear and Non-linear Mechanical Behavior of Polycrystals
(2013)
This work is dedicated to the numerically efficient simulation of the material response of polycrystalline aggregates. Therefore, crystal plasticity is combined with a new non-linear homogenization scheme, which is based ...
Human Pose Estimation with Implicit Shape Models
(2014)
This work presents a new approach for estimating 3D human poses based on monocular camera information only. For this, the Implicit Shape Model is augmented by new voting strategies that allow to localize 2D anatomical ...
Hydrodynamic instabilities and entrainment in two-layer stratified flows down a slope
(2007)
Fluid mechanical problems related to two-layer flows are of considerable interest in a variety of geophysical, atmospheric and engineering contexts. A two-layer counter-current flow system over a submerged sill is investigated. ...
Hydrodynamic processes at the water-sediment interface of streambeds
(2008)
Simultaneous 2D pressure and 2D velocity information at the rough water-sediment interface of streambeds were gained by a newly developed measurement setup. In the bed the pressure fluctuations decay exponentially within ...
Ideal und Konzept des Grundeinkommens: zur Struktur einer über sich selbst hinausweisenden Idee
(2010)
Das bedingungslose Grundeinkommen ist Gegenstand einer stark polarisierten Debatte zwischen ebenso unbedingten Befürwortern wie Gegnern. Das Buch vertritt demgegenüber eine differenzierte These: Demnach entfaltet sich das ...
Das historische Zentrum von Kabul, Afghanistan : Grundlagenermittlung für eine Strategie der Wiederbelebung
(2007)
Für die Wiederbelebung des Zentrums von Kabul sollen in Vergessenheit geratene lokale und traditionelle Elemente sowie Aspekte der Selbstverwaltung herausgearbeitet und gestärkt werden.Die bis zu 65 % zerstörte ...
Impact of grain coats on quartz overgrowth and Reservoir properties
(2017)
Syntaxial overgrowth cementation, and thereby reservoir quality, can be affected by grain coating phases inhibiting nucleation. Reaction kinetics provide a means to model the development of cement phases over time. Additional ...
The impact of interfaces on the performance of organic photovoltaic cells
(2010)
Organic photovoltaic is an attractive technology to solve future energy supply scenarios. To further increase the potential of this technology novel absorber materials and interface materials have to be developed. In this ...
The impact of inter-vehicle communication on vehicular traffic
(2009)
The work addresses communication networks established over radio equipped vehicles in our everyday road traffic, so called Vehicular Ad Hoc Networks (VANETs), and discusses their impact on two major goals, namely traffic ...
Implementation and application of the explicitly correlated coupled-cluster method in Turbomole
(2009)
In this thesis the implementation of the explicitly correlated coupled-cluster singles-and-doubles model is presented. This tool is capable of efficiently calculating CCSD energies at the basis set limit with relatively ...
