Photo-Realistic Rendering of Fiber Assemblies
(2008)
In this thesis we introduce a novel uniform formalism for light scattering from filaments, the Bidirectional Fiber Scattering Distribution Function (BFSDF). Similar to the role of the Bidirectional Surface Scattering ...
Counting and Integrating Microelectronics Development for Direct Conversion X-ray Imaging
(2008)
A novel signal processing concept for X-ray imaging with directly converting pixelated semiconductor sensors is presented. The novelty of this approach compared to existing concepts is the combination of charge integration ...
Thermal and Nonthermal Emission from the Nearby Galaxy M33: A Multi-Scale Study of Infrared and Radio Emission
(2008)
A multi-wavelength study of radio and IR emission from the nearby galaxy M33 is presented. We focus on three main topics: 1) energy sources of IR emission and its correlation with radio continuum emission at different ...
Measurement of Transverse Momentum Dependent Asymmetries with COMPASS Experiment at CERN
(2008)
The COMPASS experiment, which started running at the European Council for Nuclear Research, CERN, in Geneva in 2001, is currently investigating in a wide ranging programme the spin structure of the nucleon through ...
Infrared sense in snakes: behavioural and anatomical examinations (Crotalus atrox, Python regius, Corallus hortulanus)
(2008)
The ability to detect infrared (IR) radiation is a characteristic of boids and pitvipers. These snakes possess highly sensitive IR receptors, often embedded in pit organs, which enable them to locate IR sources independently ...
Sustainable tourism and the influence of privatization in protected area management: A case of Kinabalu Park, Malaysia
(2008)
The worldwide evolution of park management has revealed the dual roles of parks in meeting nature conservation and social objectives. Sustainable tourism is able to support these roles by providing financial support to ...
Clumpy Dust Tori in Active Galactic Nuclei
(2008)
Active Galactic Nuclei (AGN) are amongst the most luminous objects in the universe. The source of their activity is accretion onto a supermassive black hole in the center of the galactic nucleus. The various phenomena ...
The Adsorption Geometry of PTCDA on Ag(111): an NIXSW Study
(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 ...
Pensionspferdehaltung in der Akzeptanz landwirtschaftlicher Betriebsleiter
(2008)
Um die langfristige Existenz landwirtschaftlicher Betriebe abzusichern, ist ein kontinuierliches Wachstum erforderlich. Als eine Möglichkeit hierfür bieten sich Erwerbskombinationen wie beispielsweise die „klassische“ ...
Kommunales Kennzahlenmanagement am Beispiel von Vermessungs- und Katasterämtern in Nordrhein-Westfalen
(2008)
Seit Mitte der 1990er Jahre werden in den kommunalen Verwaltungen in Deutschland Maßnahmen zur Verwaltungsmodernisierung entwickelt. Kennzahlen nehmen dabei als Instrument der Steuerungsunterstützung eine Schlüsselfunktion ...
