Characteristic updrafts for computing distribution-averaged cloud droplet number and stratocumulus cloud properties

A computationally effective framework is presented that addresses the contribution of subgrid-scale vertical velocity variations in predictions of cloud droplet number concentration (CDNC) in large-scale models. Central to the framework is the concept of a ...

Use of Force Spectroscopy to Investigate the Adhesion of Living Adherent Cells

Nicolas Blondiaux, Harry Heinzelmann, Mona Julia Katharina Klein, Raphaël Pugin, Martha Liley

The use of force spectroscopy to study the adhesion of living fibroblasts to their culture substrate was investigated. Both primary fibroblasts (PEMF) and a continuous cell line (3T3) were studied on quartz surfaces. Using a fibronectin- coated AFM cantile ...

Sequential Anisotropic Multichannel Wiener Filtering with Rician Bias Correction Applied to 3D Regularization of DWI Data

Jean-Philippe Thiran, Leila Cammoun

It has been shown that the tensor calculation is very sensitive to the presence of noise in the acquired images, yielding to very low-quality Diffusion Tensor Images (DTI) data. Recent investigations have shown that the noise present in the Diffusion Weigh ...

On Random Tomography with Unobservable Projection Angles

Victor Panaretos

We formulate and investigate a statistical inverse problem of a random tomographic nature, where a probability density function on

\mathbb{R}^3

is to be recovered from observation of finitely many of its two-dimensional projections in random and unobserv ...

Plasma transport and turbulence in the Helimak: Simulation and experiment

Paolo Ricci, Bo Li

The Helimak experiment produces a toroidal plasma with a helical magnetic field. A simulation-experiment comparison of turbulence in this device is presented, focusing on parameter regimes in which the turbulence is dominated by interchange modes with k(pa ...

Framework for simulating deformable models and estimating their physical properties

Fabian Kappeler

This work describes the development of a software framework allowing to simulate range data acquired with different kind of sensors such as stereo camera and ultrasonic probe. The sensors characteristic error are modeled with probability density functions. ...

A New Measure of Travel Time Reliability for In-Vehicle Navigation Systems

This article introduces a new measure of travel time reliability for implementation in the dynamic routing algorithm of an intelligent car navigation system. The measure is based on the log-normal distribution of travel time on a link and consists of two i ...

Fast Texture Segmentation Model based on the Shape Operator and Active Contour

Jean-Philippe Thiran, Xavier Bresson, Nawal Houhou

We present an approach for unsupervised segmentation of natural and textural images based on active contour, differential geometry and information theoretical concept. More precisely, we propose a new texture descriptor which intrinsically defines the geom ...

Stochastic sediment-Vegetation dynamics in an Alpine braided river

Paolo Perona, Peter Molnar

We propose a stochastic modelling framework to simulate the spatially lumped sediment and vegetation dynamics in a flood plain of a braided gravel bed river as an alternative to detailed morphodynamic modelling. The idea is that floods intermittently erode ...

Bio-inspired self-organizing cellular systems

Daniel Mange, Joël Rossier, Fabien Vannel

Bio-inspiration borrows three properties characteristic of living organisms: multicellular architecture, cellular division, and cellular differentiation. Implemented in silicon according to these properties, our self-organizing systems are able to grow, to ...
