From thin plates to Ahmed bodies: linear and weakly nonlinear stability of rectangular prisms
Edouard Boujo, Giuseppe Antonio Zampogna
We study the stability of laminar wakes past three-dimensional rectangular prisms. The width-to-height ratio is set to W/H = 1.2, while the length-to-height ratio 1/6 < L/H < 3 covers a wide range of geometries from thin plates to elongated Ahmed bodies. F ...
CAMBRIDGE UNIV PRESS2023Acoustic dispersive prism
Juan Ramon Mosig, Hervé Lissek, Sami Driss Karkar, Seyyed Hussein Seyyed Esfahlani
The optical dispersive prism is a well-studied element, which allows separating white light into its constituent spectral colors, and stands in nature as water droplets. In analogy to this definition, the acoustic dispersive prism should be an acoustic dev ...
2016Optical prism for creating multiple views of an image
Theo Lasser, Marcel Leutenegger, Stefan Geissbuehler
Optical prism comprising two external parallel and reflecting surfaces, one internal interface, parallel to said surfaces and acting as light splitter; said prism furthermore comprising an entrance side forming an angle β with respect to said interface and ...
2016Two-dimensional polymer grating and prism on Bloch surface waves platform
Hans Peter Herzig, Elsie Barakat, Libo Yu, Joab Di Francesco
A one-dimensional photonic crystal sustaining Bloch Surface Waves (BSWs) is used as a platform for two-dimensional integrated optics. The dielectric platform shows low loss, long propagation distance and high surface field enhancement. In order to study th ...
Optical Society of America2015PRISM: Recovery of the primordial spectrum from Planck data
Aim. The primordial power spectrum describes the initial perturbations that seeded the large-scale structure we observe today. It provides an indirect probe of inflation or other structure-formation mechanisms. In this Letter, we recover the primordial pow ...
EDP Sciences2014Phase-Shift Master-Slave Mechanisms for High Angular-Speed Wedge-Prism Systems
Reymond Clavel, Olivier Chappuis
Laser micro-machining requires high dynamic laser spot trajectory and accuracy to control the laser beam scanning. A well-known technique to scan a laser beam over a specimen is to use a pair of wedge-prisms. However, it is difficult to master-slave the ph ...
Taylor & Francis Inc2013Limits and artefacts of reflective imaging goniophotometers for complex solar façade systems
Marilyne Andersen, Boris Clément Karamata
The design of systems for solar light collection, modulation and/or distribution requires a thorough knowledge of their optical properties. The angular distribution of the scattered incident light flux, described by the Bidirectional Scattering Distributio ...

When aliquid drop approaches a flat solid surface, the airbeneath it is compressed,flattening the bottom of the drop andforcing initial contact to occur in aring-shape, trapping a pocketof air in its center as two wetting frontsrapidly expand botho ...
2011Rehabilitating patients with left spatial neglect by prism exposure during a visuomotor activity
Roberta Ronchi, Giuseppe Vallar
OBJECTIVE: Adaptation to prisms displacing the visual scene rightward is a therapeutic tool for left unilateral spatial neglect (USN). We aimed at comparing the effects of the classic adaptation procedure (repeated pointing toward visual targets, control t ...
2010Experimental investigation on the connection between flow fluctuations and vorticity dynamics in the near wake of a triangular prism placed vertically on a plane
Experiments are carried out to investigate on the connection between flow fluctuations and dynamics of different vorticity structures in the wake of an equilateral triangular prism placed vertically on a plane with its apex edge against the incoming flow. ...
