The silent politics of educational disadvantage and the National Anti-poverty Strategy

Educational disadvantage is an essentially contested, political concept. At the same time there is a ‘phoney consensus’ surrounding the issue, i.e., policy debates on the topic often fail to reflect this contestation. This lack of awareness of the politica ...

Gravity Solitary Waves By Minimization: An Uncountable Family

Boris Buffoni

We improve and simplify the minimization method for solitary waves in two cases: firstly, when the surface tension is weak (that is, the Bond number is < 1/3) and the depth is finite, and secondly, when the depth is infinite. In a previous work on the firs ...

Atoms of all channels, unite! Average case analysis of multi-channel sparse recovery using greedy algorithms

Pierre Vandergheynst, Rémi Gribonval, Karin Schnass

This paper provides new results on computing simultaneous sparse approximations of multichannel signals over redundant dictionaries using two greedy algorithms. The first one, p-thresholding, selects the S atoms that have the largest

Influence of the widening of a tributary on confluence morphology: preliminary results

Anton Schleiss, Koen Blanckaert, Marcelo Leite Ribeiro, Simon Wampfler

The aim of this work is to obtain a better understanding of the morphological development in alpine river confluences, where special attention is given to the widening of the tributary channel and its influence on bed morphology evolution. Hydraulic tests ...

Weyssenhoff fluid dynamics in general relativity using a 1 + 3 covariant approach

Sylvain Bréchet

The Weyssenhoff fluid is a perfect fluid with spin where the spin of the matter fields is the source of torsion in an Einstein–Cartan framework. Obukhov and Korotky showed that this fluid can be described as an effective fluid with spin in general relativi ...

Objective Evaluation of the Perceptual Quality of 3D Watermarking

Touradj Ebrahimi, Elisa Drelie Gelasca

In this paper an objective metric to measure the perceptual quality of watermarked 3D meshes is presented. The metric, which is based on a black-box approach, relies on the measurement of the roughness of 3D meshes before and after the insertion of the wat ...

Semi-Automated Design of a MOS Current Mode Logic Standard Cell Library from Generic Components

Yusuf Leblebici, Stéphane Badel, Ilhan Hatirnaz

This paper describes the design and semi-automated generation of a MOS current-mode logic standard cell library. A set of generic components implementing a wide range of combinational and sequential functions is proposed. The layout of the generic componen ...

From a Static Impossibility to an Adaptive Lower Bound: The Complexity of Early Deciding Set Agreement

Rachid Guerraoui, Bastian Pochon

Set agreement, where processors decisions constitute a set of outputs, is notoriously harder to analyze than consensus where the decisions are restricted to a single output. This is because the topological questions that underly set agreement are not about ...
