Stochastic optimization of sailing trajectories in an upwind regatta

Stephan Morgenthaler, Robert Dalang, Frédéric Dumas, Sylvain Sardy

In a sailboat race, the navigator's attempts to plot the fastest possible course are hindered by shifty winds. We present mathematical models appropriate for this situation, which use statistical analysis of wind fluctuations and are amenable to stochastic ...

A microchip emitter for solid phase extraction – gradient elution – mass spectrometry

Hubert Girault, Natalia Gasilova, Liang Qiao, Dmitry Momotenko, Mohammad Reza Pourhaghighi

A microchip electrospray emitter with a magnetic bead trap has been designed for solid phase extraction-gradient elution-mass spectrometry (SPE-GEMS). The goal of this method is the detection of analytes at low concentrations and it is here demonstrated us ...

A Nonlinear Dynamic Strategy for Mathematical Modeling and Simulation of Stabilized Platform in Planar Motion in One Body and Three Bodies

Mehmet Hasan Mutlu

Abstract Mathematical modeling and simulation of a head stabilization platform. The stabilization platform is capable of moving on the pitch degree of freedom. The platform is modeled in two different approaches; considering only the mass of the platform ( ...

A High–Performance Parallel Implementation of the Chambolle Algorithm

David Atienza Alonso, Abdulkadir Akin, Ivan Beretta, Alessandro Antonio Nacci

The determination of the optical flow is a central problem in image processing, as it allows to describe how an image changes over time by means of a numerical vector field. The estimation of the optical flow is however a very complex problem, which has be ...
