Surface optofluidics

Demetri Psaltis, Andreas Vasdekis, Wuzhou Song, Jae-Woo Choi, Julien Cuennet, Luciano De Sio

Surfaces -defined as the interfaces between solids and liquids- have attracted much attention in optics and biology, such as total internal reflection imaging (TIRF) and DNA microarrays. Within the context of optofluidics however, surfaces have received li ...

Implicit Meshes for Effective Silhouette Handling

Pascal Fua, Mathieu Salzmann, Slobodan Ilic

Using silhouettes in uncontrolled environments typically requires handling occlusions as well as changing or cluttered backgrounds, which limits the applicability of most silhouette based methods. For the purpose of 3--D shape modeling, we show that repres ...

Reconstruction of ion temperature profiles from single chord NPA measurements on the TCV tokamak

Basil Duval, Alexander Karpushov, Christian Schlatter

The flux of charge exchange ( CX) neutrals measured by neutral particle analysers ( NPAs) is the line integral along the viewline of the NPA and contains information about the ion energy distribution of the observed plasma. On the Tokamaka a Configuration ...

Surface parameterization and optimum design methodology for hydraulic turbines

This thesis presents a methodology for the design optimization of hydraulic runner blades. The originality of the methodology comes from the geometric definition of the blade shapes, which uses parametric surfaces instead of a set of profiles. The main adv ...

Surface Parametrization of a Francis Runner Turbine for Optimum Design

François Avellan

The aim of this paper is to apply a surface parameterization to a blade. This geometric representation should be used as a practical tool in the process of design optimization. Most parameterizations are based on blade section approaches. The parameters ar ...

Liquid crystal alignment on replicated nanostructured surfaces

Toralf Scharf

Interaction of liquid crystals with nanostructured surfaces is studied experimentally. Whereas photolithographic or ATM methods mere used in the past for surface structuring, we use besides photolithography essentially replication methods for the creation ...

Colored visualization of shape differences between bones

Daniel Thalmann, Sofiane Sarni, Ik Soo Lim

This article addresses visualization of deformation or shape differences between bones while conventional visualization techniques are often about a single bone such as its 3D reconstruction. Given a pair of bones with a set of corresponding anatomical lan ...

Reorganization of adsorbed films by coadsorbing species

Sylvie Roke

Coadsorption of CO and butane on a Pt(533) surface leads to a dynamical system in which both molecules influence the adsorption behavior of each other. Adsorbing butane on a Pt(533) surface with CO on atop step sites leads to tilting of CO molecules of at ...

Polarization-modulated FTIR spectroscopy of lipid/gramicidin monolayers at the air/water interface

Horst Vogel

Monolayers of gramicidin A, pure and in mixts. with dimyristoylphosphatidylcholine (DMPC), were studied in situ at the air/H2O and air/D2O interfaces by polarization-modulated IR reflection absorption spectroscopy (PM-IRRAS). Simulations of the entire set ...
