Modal Response of Hydraulic Turbine Runners

The mechanical design of hydraulic turbines is conditioned by the dynamic response of the runner that is usually estimated by a computational model. Nevertheless, the runner has complex boundary conditions that are difficult to include in the computational ...

Modelling pattern transfer in stencil lithography

Jürgen Brugger, Marc Antonius Friedrich van den Boogaart

The race to shrink feature sizes requires the limits of conventional lithography to be extended to high-throughput, low cost, reliable and well-controlled processes of which stencilling is a promising candidate for nanoscale applications. Identifying, pred ...

Compositional model for predicting multilayer reflectances and transmittances in color reproduction

Mathieu Hébert

The color of materials such as paints, prints and glass may be characterized by a reflectance or a transmittance spectrum. Modeling their reflectance and their transmittance requires describing the interaction of light, from the light source to the observe ...

Analytical modeling of the apparent d(33) piezoelectric coefficient determined by the direct quasistatic method for different boundary conditions

Nava Setter, Dragan Damjanovic

The longitudinal piezoelectric coefficient d(33) measured by the quasistatic (Berlincourt-type) method is strongly dependent on the sample aspect ratio (thickness/lateral dimension) and the type of contacts used to collect the charge and apply the pressure ...

Weak solution of a stationary convection-diffusion model describing binary alloy solidification processes

Jacques Rappaz

Our goal is to study the existence of weak solution for the stationary system of equations describing the solidification process of a binary alloy confined in a bounded regular domain in R-3 and having mixed boundary conditions. (c) 2005 Elsevier Ltd. All ...

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

Online Registration Tool and Markerless Tracking for Augmented Reality

Touradj Ebrahimi, Yousri Abdeljaoued

This paper presents a markerless tracking algorithm for augmented reality with no constraints in the geometry of the scene. Users pose is estimated using natural feature point extraction and tracking, and the epipolar geometry constraint between camera vi ...

Gravitating field-theoretical branes and their excitations

Katarzyna Zuleta Estrugo

This thesis is devoted to studying field-theoretical branes in warped geometries, with emphasis on brane excitations and properties of background solutions. Firstly, we examine the features of a model in which our universe is represented by a local string- ...

Semantics-based representation of virtual environments

Daniel Thalmann, Frédéric Vexo

In this paper we present an object representation based on the semantics and functionality of interactive digital items - virtual objects - within a virtual environment (VE). We consider every object participating in a VE application not only as a 3D shape ...

A Meeting Browser Evaluation Test

We introduce a browser evaluation test (BET), and describe a trial run application of the test. The BET is a method for assessing meeting browser performance using the number of observations of interest found in the minimum amount of time as the evaluation ...
