Adaptive numerical simulation of contact problems: Resolving local effects at the contact boundary in space and time
Walloth, Mirjam (2012-10-24)This thesis is concerned with the space discretization of static and the space and time discretization of dynamic contact problems. In particular, we derive a new efficient and reliable residual-type a posteriori error ... -
Adaptive Scattered Data Fitting with Tensor Product Spline-Wavelets
Castaño Díez, Daniel (2005)The core of the work we present here is an algorithm that constructs a least squares approximation to a given set of unorganized points. The approximation is expressed as a linear combination of particular B-spline wavelets. ... -
Adding New Functionalities to Optical Fiber Cavities by Direct Laser Writing

Adherence Management for Cancer Patients on Capecitabine
Krolop, Linda (2014-01-13)The oral anticancer drug capecitabine is given twice daily for 14 days followed by a seven day rest period. Adequate patient adherence is essential for treatment success.
The present study aimed at developing and ... -
Adsorption and Selective Hydrogenation of α, β-unsaturated Aldehydes on Pt(111) and Pt-Sn Model Catalysts
Haubrich, Jan (2007)Studies of complex interacting systems such as the adsorption of α , β-unsaturated aldehydes on model catalyst surfaces are a present day challenge. Although numerous studies have been published on the catalytical properties ... -
The Adsorption Geometry of PTCDA on Ag(111): an NIXSW Study
Hauschild, Annegret (2008)The bonding lengths of a large pi-conjugated molecule which was adsorbed on a metal surface were determined for the first molecular layer. The system consisting of the organic molecules 3,4,9,10-Perylenetetracarboxylic ... -
Adsorption von kleinen und großen Molekülen auf katalytisch aktiven Metalleinkristallelektroden
Kaul, Jan Kristof (2017-12-20)Die Adsorptionsprozesse sind für die Oberflächenreaktionen und insbesondere für die heterogene Katalyse entscheidende Reaktionsschritte. In dieser Arbeit werden die Adsorptionskinetiken und -modelle von adsorbiertem ... -
Adsorption von Phthalocyanin-Molekülen auf anisotropen Oberflächen
Pertram, Tobias Martin (2014-06-04)Verstärkt wird in den letzten Jahren das Adsorptionsverhalten organischer Moleküle auf Oberflächen untersucht. Das Ziel solcher Untersuchungen sind "funktionalisierte Oberflächen" und die Optimierung der an ihnen ablaufenden ... -
