Thermoviscoelastic anisotropic analysis of process induced residual stresses and dimensional stability in real polymer matrix composite components

A design tool able to predict the residual stress state and dimensional stability of large complex shaped composite parts has been developed. It is based on a finite element model, using a three-dimensional anisotropic thermo-viscoelastic formulation. Asym ...

Multiresolution Motion Estimation for Omnidirectional Images

Pascal Frossard, Pierre Vandergheynst, Ivana Tosic, Iva Bogdanova Vandergheynst

This paper presents a novel local motion estimation algorithm for omnidirectional images. The algorithm captures correlation between two spherical images of a scene, taken from arbitrary viewpoints, with the objective to reduce the encoding rate of these i ...

Holistic Radiation Modelling with a Fast Simplified Radiosity Algorithm

Darren Robinson

The radiant external environment may be described by two hemispheres, above and below the horizontal plane, which are discretised into patches of known solid angle. Occlusions to these patches may be combined and represented as some patch fraction for whic ...

Strong electron-electron and electron-phonon interactions in one- and two-dimensional solids

Marco Grioni, Helmuth Berger, Luca Perfetti

We discuss the spectral signatures of strong electronic correlations and electron-phonon interactions in two representative low-dimensional systems. In the 2D compound 1T-TaSe2 a charge-density-wave (CDW) induces a narrowing of the conduction band, which t ...

Every convex polyhedron in the Euclidean space

R^d

admits both H- and V-representation. For both formats, a representation is canonical if it is minimal and unique up to some elementary operations. In this paper, we extend the usual definition of canonic ...

Nodal high-order discontinuous Galerkin methods for the spherical shallow water equations

Jan Sickmann Hesthaven

We present a high-order discontinuous Galerkin method for the solution of the shallow water equations on the sphere. To overcome well-known problems with polar singularities, we consider the shallow water equations in Cartesian coordinates, augmented with ...

A coupled atomistic/continuum model of defects in solids

William Curtin, Ronald Earle Miller

A method is introduced for reducing the degrees of freedom in simulations of mechanical behavior of materials without sacrificing important physics. The method essentially combines the quasicontinuum (QC) method with continuum defect models such as the dis ...

Structural dynamics in quantum solids. II. Real-time probing of the electronic bubble formation in solid hydrogens

Majed Chergui, Franco Vigliotti, Luigi Bonacina

The ultrafast dynamics of electronic bubble formation upon excitation of the A(3ss) Rydberg state of NO trapped in solid H2 and D2 was studied by femtosecond pump-probe spectroscopy. The evolution of the spherical bubble is followed in real time by a probe ...

Efficient simplification of point-sampled surfaces

Mark Pauly

In this paper we introduce, analyze and quantitatively compare a number of surface simplification methods for point-sampled geometry. We have implemented incremental and hierarchical clustering, iterative simplification, and particle simulation algorithms ...

Flexible bearings for high precision mechanisms in accelerator facilities

Simon Nessim Henein

While in conventional mechanical bearings motion is obtained by sliding or rolling between solid bodies with the resulting mechanical non-linearities, flexible bearings rely on the elastic properties of matter allowing several advantages to be obtained. Co ...
