On stability of the catenoid under vanishing mean curvature flow on Minkowski space

Joachim Krieger

We establish basic local existence as well as a stability result concerning small perturbations of the Catenoid minimal surface in R-3 under hyperbolic vanishing mean curvature flow. ...

Processes governing the flow redistribution in sharp river bends

Koen Blanckaert

Insight is provided in hydrodynamic processes governing the velocity redistribution in sharp river bends based on simulations of three recent experiments by means of Blanckaert and de Vriend's (2003, 2010) reduced-order nonlinear model without curvature re ...

Geodesic Active Fields

Dominique Zosso

Image registration is the concept of mapping homologous points in a pair of images. In other words, one is looking for an underlying deformation field that matches one image to a target image. The spectrum of applications of image registration is extremely ...

Meander dynamics: A nonlinear model without curvature restrictions for flow in open-channel bends

Koen Blanckaert

Despite the rapid evolution of computational power, simulation of meander dynamics by means of reduced and computationally less expensive models remains practically relevant for investigation of large-scale and long-term processes, probabilistic prediction ...

Positional, metric, and curvature control for constraint-based surface deformation

Mark Pauly

We present a geometry processing framework that allows direct manipulation or preservation of positional, metric, and curvature constraints anywhere on the surface of a geometric model. Target values for these properties can be specified point-wise or as i ...

An experimental study on main flow, secondary flow and turbulence in open-channel bends with emphasis on their interaction with the outer-bank geometry

Alexandre José Pessanha De Oliveira Caimoto Duarte

This research focus on the influence of bank inclination and roughness on the near-bank flow patterns which is relevant for bank protection, bank erosion and design of stable river configuration. Foregoing studies have been carried out mostly in rectangula ...

Particle migration in a concentrated suspension flowing between rotating parallel plates: Investigation of diffusion flux coefficients

Etienne Pierre Lemaire

This paper reports an experimental and numerical study conducted to investigate the behavior of macroscopic monomodal concentrated suspensions (40%) undergoing a creeping torsional flow between two rotating plates. An experimental technique based on the de ...

Unsupervised Selective Anisotropic Feature Diffusion for Cortical Surface Registration

Jean-Philippe Thiran, Olivier Cuisenaire

In this paper we use the theory of geometric curve and surface evolution to diffuse an object preserving their important features. We do that using a curvature flow method with a novel influence function. The proposed influence function takes profit from t ...

Flow and turbulence in sharp open-channel bends

Koen Blanckaert

The sustainable development of rivers requires a knowledge on the three-dimensional mean flow field and the turbulence in complex morphologies. In a future, the computational capacity will be sufficient to simulate numerically the fine details of the flow. ...

Prédiction de l'érosion de cavitation

Predicting the rate and location of cavitation erosion is a complex problem that motivated an important amount of basic and applied research in the fields of hydrodynamics, mechanical science and metallurgy. Using an original approach, the so-called energe ...
