Liquid film instability of an internally coated horizontal tube
François Gallaire, Edouard Boujo, Yves-Marie François Ducimetière, Shahab Eghbali
We study numerically and theoretically the gravity-driven flow of a viscous liquid film coating the inner side of a horizontal cylindrical tube and surrounding a shear-free dynamically inert gaseous core. The liquid-gas interface is prone to the Rayleigh-P ...
AMER PHYSICAL SOC2023Bounds on photon scattering
Denis Karateev, Kelian Philippe Häring, Marco Meineri, Aditya Hebbar
We study 2-to-2 scattering amplitudes of massless spin one particles in space-time dimensions, like real world photons. We define a set of non-perturbative observables (Wilson coefficients) which describe these amplitudes at low energies. We use full ...
2022Lattice formulation of axion inflation. Application to preheating
Daniel Garcia Figueroa, José Roberto Canivete Cuissa
We present a lattice formulation of an interaction phi/Lambda F (F) over tilde between an axion and some U(1) gauge sector with the following properties: it reproduces the continuum theory up to O(dx(mu)(2)) corrections, it preserves exact gauge invariance ...
IOP PUBLISHING LTD2019A comprehensive framework for visual quality assessment of light field tensor displays
In recent years, light field technology has attracted the interest of academia and industry, thanks to the possibility of rendering 3D scenes in a more realistic and immersive way. In particular, light field displays have been consistently investigated for ...
Society for Imaging Science and Technology2019Vortical structures in the near wake of tabs with various geometries
The vortical structures and turbulence statistics in the near wake of rectangular, trapezoidal, triangular and ellipsoidal tabs were experimentally studied in a refractive-index-matching channel. The tabs share the same bulk dimensions, including a 17Â mm ...
2017Connecting space and justice in metropolitan Porto
Ana Moura Bastos de Fernandes Póvoas
This investigation on spatial justice, while being fundamental research, has empirical pertinence and operational quality in the form of a justice-minded urbanism. Connecting the concreteness of cities with the societal objectives of development and of jus ...
EPFL2016How to explore the "spatialities" of avatars in a virtual world? Example of the project Magic Ring in Second Life
This chapter presents a project developed in a study about the narrative dimension of the immersion process in the virtual world of Second Life. This digital universe is not usual because users can build the digital environment themselves, that means that ...
Inter-Disciplinary Press2014COSMOGRAIL: the COSmological MOnitoring of GRAvItational Lenses XIII. Time delays and 9-yr optical monitoring of the lensed quasar RX J1131-1231
Frédéric Courbin, Georges Meylan, Malte Tewes, Nicolas Cantale
We present the results from nine years of optically monitoring the gravitationally lensed z(QSO) = 0.658 quasar RX J1131-1231. The R-band light curves of the four individual images of the quasar were obtained using deconvolution photometry for a total of 7 ...
Edp Sciences S A2013Exploitation of a general-coordinate guiding centre code for the redistribution of fast ions in deformed hybrid tokamak equilibria
Jonathan Graves, Wilfred Anthony Cooper, David Pfefferlé
Self-consistent fast ion distributions are usually obtained using a code that solves the guiding-centre equations, with an appropriate fast ion source (e.g. NBI pinis) and sink (e.g. collision operators). Straight field-line coordinate systems, such as Boo ...
Iop Publishing Ltd2012Adaptive Open-Loop Aerobatic Maneuvers for Quadrocopters
We describe a process for enabling quadrocopters to perform and improve upon aerobatic maneuvers. We describe such maneuvers as a set of desired keyframes and a parametrized input trajectory. The full state trajectory of the vehicle is left unspecified - o ...
