Quantum graph approximations of thin branching structures IAMCS-KAUST Speaker Seminar April 8, 2009 4:00 Dr. Olaf Post Abstract Many physical systems have branching structure of thin transversal diameter. One can name for instance quantum wire circuits, thin branching waveguides, or carbon nano-structures. In applications, such systems are often approximated by the underlying one-dimensional graph structure, a so-called […]
FEM for a Membrane Problem October 26, 2009 10:00 a.m. M. Sebastian Pauletti Abstract When lipid molecules are immersed in aqueous environment they spontaneously aggregate into a membrane made up of two mono-molecular layers. The membrane forms an encapsulating bag called vesicle. This happens because lipids consist of a hydrophilic head group and a hydrophobic […]
Surface Relaxation Below the Roughening Temperature October 12, 2009 10:00 a.m. Robert Kohn Abstract Epitaxial films are often grown or annealed below their roughening temperature. The microscopic physics involves the attachment and detachment of atoms at steps, and the diffusion of atoms across terraces. The macroscopic consequences of these atomic-scale mechanisms are still poorly understood.
Generation of Analysis Suitable Geometry from Discrete Data Sets: Ice Sheets of Antarctica April 23, 2010 2:30 p.m. Nathan Collier Abstract This talk will discuss available data for the geometric modeling of the ice sheets of Antarctica. These geometries are a key part of an effort [1,2] to model the sheet’s flow over the continent, […]
The Visualization of Uncertainty 2010 2:30 p.m. Kristin Potter Abstract The graphical depiction of uncertainty information is emerging as a problem of great importance in the field of visualization. Scientific data sets are not considered complete without indications of error, accuracy, or levels of confidence, and this information is often presented as charts and tables […]
