A Fast Method for Finding Range of Motion in the Human Joints

Daniel Thalmann, Ronan Boulic, Ehsan Arbabi

Finding the range of motion for the human joints is a popular method for diagnosing joint diseases. By current technology, it is more trustable and easier to find the range of motion by employing computer based models of the human tissues. In this paper we ...

Getting more out of an incommensurately modulated structure: the example of K_5Yb(MoO_4)_4

Gervais Chapuis, Alla Arakcheeva

A method based on the superspace approach is presented with the aim of generating a family of modular structures from a single incommensurately modulated structure. This approach based on the variation of the modulation vector q is applied to the generatio ...

A generalization of distinct element method to tridimensional particles with complex shapes

Thomas Liebling, Lionel Pournin

The distinct element method was originally designed to handle spherical particles. Here, this method is generalized to a wider range of particle shapes called spherosimplices. A contact detection method is given as well which uses weighted Delaunay triangu ...

Calculation of the torque on dielectric elliptical cylinders

Hans Peter Herzig

We investigate the small-particle phonon-polariton response of several microstructures that are made of silicon carbide (SiC). Phonon polaritons can be excited in a wavelength region between 10 and 12 μm. Simple structures such as elliptical cylinders supp ...

An exact formula for "tooth-to-tooth" permeance

Yves Perriard, Marcel Jufer, Miroslav Markovic

We present a new, completely original exact method to determine the permeance between two opposing iron teeth. This configuration is important because it is often encountered in electrical machines and apparatus. The method is based on conformal mapping. T ...

Approximation of multi-scale elliptic problems using patches of finite elements

Jacques Rappaz

In this paper we present a method to solve numerically elliptic problems with multi-scale data using multiple levels of not necessarily nested grids. The method consists in calculating successive corrections to the solution in patches whose discretizations ...

From Samples to Objects in Kernel Methods

Samy Bengio, Alexei Pozdnoukhov

This paper presents a general method for incorporating prior knowledge into kernel methods. It applies when the prior knowledge can be formalized by the description of an object around each sample of the training set, assuming that all points in the given ...

The separation of surface and bulk contributions in ELNES spectra

Cécile Hébert

We present a method to separate surface from volume contributions in the fine structure of ionization edges in electron energy loss spectrometry (ELNES). It is based on spectra taken at two positions with different surface-to-volume ratio. Contrary to the ...

Thermo-mechanical properties of hyperbranched polymer modified epoxies

The thermo-mechanical properties of hyperbranched polymer-epoxy blends and their dependence on hyperbranched polymer shell chemistry were investigated. Hyperbranched polymers were shown to be able to increase resin toughness by inducing both a heterogeneou ...
