From kirigami to hydrogels: a tutorial on designing conformally transformable surfaces

Elastic surfaces that morph between multiple geometrical configurations are of significant engineering value, with applications ranging from the deployment of space-based PV arrays, the erection of temporary shelters, and the realization of flexible displa ...

A scenario modeling pipeline for COVID-19 emergency planning

Francisco Javier Perez Saez, Joseph Chadi Benoit Lemaitre

Coronavirus disease 2019 (COVID-19) has caused strain on health systems worldwide due to its high mortality rate and the large portion of cases requiring critical care and mechanical ventilation. During these uncertain times, public health decision makers, ...

Deformable block based motion estimation in omnidirectional image sequences

Pascal Frossard, Francesca De Simone

This paper presents an extension of block-based motion estimation for omnidirectional videos, based on a camera and translational object motion model that accounts for the spherical geometry of the imaging system. We use this model to design a new algorith ...

Geometry-driven quantization for omnidirectional image coding

Pascal Frossard, Francesca De Simone

In this paper we propose a method to adapt the quantization tables of typical block-based transform codecs when the input to the encoder is a panoramic image resulting from equirectangular projection of a spherical image. When the visual content is project ...

Observation of Transverse Polarization Asymmetries of Charged Pion Pairs in e(+)e(-) Annihilation near root s=10.58 GeV

Mingkui Wang, Olivier Schneider, Chao Wang, Yiming Li, Vladislav Balagura, Remi Léandre Albert Louvot

The interference fragmentation function translates the fragmentation of a quark with a transverse projection of the spin into an azimuthal asymmetry of two final-state hadrons. In e(+)e(-) annihilation the product of two interference fragmentation function ...

Experimental investigation into localized instabilities of mixed Rayleigh-Benard-Poiseuille convection

Peter Monkewitz

The stability of the Rayleigh-Benard-Poiseuille flow in a channel with large transverse aspect ratio (ratio of width to vertical channel height) is studied experimentally. The onset of thermal convection in the form of 'transverse rolls' (rolls with axes p ...
