Fourier space imaging of light localization at a photonic band-edge located below the light cone

We observe light localization in a two-dimensional geometry, induced by residual disorder at a photonic band edge located below the light cone. The combination of a spectrally selective illumination and a grating assisted k-space imaging technique allows u ...

Effect of aging on elastin functionality in human cerebral arteries

Michaël Unser, Nikolaos Stergiopoulos, Daniel Sage, Edouard Fonck, Jean Fasel

Aging affects elastin, a key component of the arterial wall integrity and functionality. Elastin degradation in cerebral vessels is associated with cerebrovascular disease. The goal of this study is to assess the biomechanical properties of human cerebral ...

Laplacian Operator, Diffusion Flow and Active Contour on non-Euclidean Images

Jean-Philippe Thiran, Pierre Vandergheynst, Xavier Bresson, Iva Bogdanova Vandergheynst

We propose here some basic approaches to direct processing of the

Functional, mechanical and geometrical adaptation of the arterial wall of a non-axisymmetric artery in vitro

Nikolaos Stergiopoulos, Paolo Silacci, Martin Zulliger

Vascular remodeling is an adaptive response to variations in the hemodynamic environment acting on the arterial wall. Remodeling translates into changes of structure, geometry and mechanical properties of the artery. Our aim was to study the remodeling res ...

Robust watermarking of point-sampled geometry

Mark Pauly

We present a new scheme for digital watermarking of point-sampled geometry based on spectral analysis. By extending existing algorithms designed for polygonal data to unstructured point clouds, our method is particularly suited for scanned models, where th ...

Spin interference and Fabry–Pérot resonances in ferromagnet–semiconductor–ferromagnet devices

Dirk Grundler

Magnetoconductance across permalloy/InAs(2DES)/permalloy double junctions in the ballistic limit is examined within the transfer-matrix formalism. We take into account Rashba spin–orbit interaction in the semiconductor as well as oblique modes in devices o ...

Green's tensor technique for scattering in two-dimensional stratified media

Olivier Martin

We present an accurate and self-consistent technique for computing the electromagnetic held in scattering structures formed by bodies embedded in a stratified background and extending infinitely in one direction (two-dimensional geometry), With this fully ...

Flow Investigation in a Francis Draft Tube : the Flindt Project

François Avellan

The flow investigation in a elbow draft tube is presented. After a review of the existing works related to the flow analysis of such component, the need of an experimental validation of the CFD tools is discussed with respect the practical interest of impr ...

Metropolis light transport for participating media

Mark Pauly

We show how Metropolis light transport can be extended both in the underlying theoretical framework and the algorithmic implementation to incorporate volumetric scattering. We present a generalization of the path integral formulation that handles anisotrop ...

Estimation of current bypass in a bipolar electrode stack

Christos Comninellis

A simple method is proposed for the estn. of the current bypass from exptl. current potential (i-U) curves measured for a bipolar reactor and with a one element cell of similar geometry. The model is valid only in the region where a linear i-U relation was ...
