Cidade, arte e política. A produção comum do espaço

Luca Giovanni Pattaroni, Yves Pedrazzini, Emmanuel Pierre Jean Ravalet, Mischa-Sébastien Piraud, Letícia Cabeçadas Do Carmo

O debate em torno das relações entre Arte e Cidade tem-se centrado na crítica das denominadas políticas de «empreendedorismo urbano», as quais estariam ligadas a uma economia «criativa» e a um mercado global de cidades. Entre as suas características estari ...

Hopping process of bound excitons under an energy gradient

Benoît Marie Joseph Deveaud, Jean-Daniel Ganière, Gwénolé Jean Jacopin, Mehran Shahmohammadi

We report on the mechanism of hopping for bound excitons under an energy gradient. By means of a Monte-Carlo simulation, we show that this mechanism explains the movement of bound excitons observed experimentally. We show that the speed of the excitons dec ...

Anderson Tower of States and Nematic Order of Spin-1 Bosonic Atoms on a 2D Lattice

Frédéric Mila, Hongyu Yang

We investigate the structure of the spectrum of antiferromagnetically coupled spin-1 bosons on a square lattice using degenerate perturbation theory and exact diagonalizations of finite clusters. We show that the superfluid phase develops an Anderson tower ...

FE modeling of micromotion at the bone-implant interface

Denis Stauffer

Nowadays, pain and mobility issues of the hip such as arthritis bring more and more people to go through a hip replacement. The primary stability of an implant is essential for the long-term success of hip arthroplasty. Excessive micromotion is an indicato ...

Spatial Degrees of Freedom of Large Distributed MIMO Systems and Wireless Ad Hoc Networks

Olivier Lévêque

We consider a large distributed MIMO system where wireless users with single transmit and receive antenna cooperate in clusters to form distributed transmit and receive antenna arrays. We characterize how the capacity of the distributed MIMO transmission s ...

A quality assessment protocol for Free-viewpoint video sequences synthesized from decompressed depth data

Touradj Ebrahimi, Philippe Hanhart

In this paper, the analysis of a subjective quality experiment consisting in assessing the quality of free-viewpoint video sequences generated from decompressed depth data is presented. In the absence of a dedicated subjective assessment protocol for the e ...

Sensitivity of hip tissues contact evaluation to the methods used for estimating the hip joint center of rotation

Daniel Thalmann, Ronan Boulic, Jérôme Schmid, Ehsan Arbabi

Computer-based simulations of human hip joints generally include investigating contacts happening among soft or hard tissues during hip movement. In many cases, hip movement is approximated as rotation about an estimated hip center. In this paper, we inves ...

Distributed static linear Gaussian models using consensus

Pavle Belanovic

Algorithms for distributed agreement are a powerful means for formulating distributed versions of existing centralized algorithms. We present a toolkit for this task and show how it can be used systematically to design fully distributed algorithms for stat ...

Analogy between Juggling and Hopping: Active Object Manipulation Approach

Auke Ijspeert

Dynamic manipulation of an active object is introduced as a general model of hopping and juggling tasks. In this setting, juggling and hopping are two extreme cases of this general model. Behavioral resemblance of these two tasks is afterwards extended to ...

Secure key exchange in wireless networks

Christina Fragouli, László Czap

We investigate the problem of exchanging a se- cret key within a group of wireless devices. In particular, we are interested in information theoretically secure key exchange schemes that enable honest nodes of a multi-hop network to establish a secret grou ...
