Lubricant transport towards tribocontact in capillary surface structures
(2018)
To counter lubricant shortage at a frictional contact (starvation), lubrication liquids, e.g. oils, are actively transported from a distant location towards the undersupplied tribocontact. This is done via small channels ...
Magnetic Resonance Imaging on Patients with Implanted Cardiac Pacemakers
(2011)
The aim of this work was to identify the patterns that can induce heating around implanted cardiac pacemakers during MRI and to develop strategies to counteract them. Two approaches were taken: computer simulations of the ...
Microstructure evolution in strontium titanate Investigated by means of grain growth simulations and x-ray diffraction contrast tomography experiments
(2014)
Understanding the physical processes during fabrication and annealing of ceramic materials is a long sought goal among material scientists. Using strontium titanate as a model system for perovskite ceramics, the present ...
Microstructural stability of nanostructured fcc metals during cyclic deformation and fatigue
(2012)
Nanostructured metals with maximal grain or twin sizes of less than 100 nm have advanced properties like increased strength.As beneficial as these microstructures can be for the strength of materials, they are not infinitely ...
Microstructure and Mechanical Behavior of Deep Drawing DC04 Steel at Different Length Scales
(2013)
The deformation behavior of steels is strongly influenced by their microstructure which is a result of the alloying elements and thermal treatments. In this work, the microstructure and the deformation behavior of a ...
MIMO OFDM Radar-Communication System with Mutual Interference Cancellation
(2017)
This work describes the OFDM-based MIMO Radar-Communication System, intended for operation in a multiple-user network, especially the automotive sector in the vehicle-to vehicle/infrastructure network. The OFDM signals ...
Ladungstransportmodell dielektrisch behinderter Entladungen
(2009)
Mit dielektrisch behinderten Entladungen (DBE) ist es möglich Lichtquellen auf dem Prinzip der Leuchtstofflampe quecksilberfrei und flächig in beliebiger Form zu gestalten.Charakteristisch für die DBE ist die Abhängigkeit ...
Ladungstransportschichten für effiziente organische Halbleiterbauelemente
(2009)
In dieser Arbeit werden flüssigprozessierte und vakuumsublimierte Ladungstransportschichten für organische Halbleiterbauelemente erforscht, wobei ein besonderer Schwerpunkt auf den n- und p-dotierten Materialsystemen liegt. ...
Lademanagement für Elektrofahrzeuge
(2017)
The present work describes a charging management with integrated charging optimization for electric vehicles that can be provided to a fleet by a fleet operator or to a group of private customers by a loading infrastructure ...
Large-scale Multi-item Auctions : Evidence from Multimedia-supported Experiments
(2012)
This book presents two experimental studies that deal with the comparison of multi-item auction designs for two specific applications: the sale of 2.6 GHz radio spectrum rights in Europe, and the sale of emissions permits ...
