Promenade dans le hors-champ. L'éclatement du centre sportif le long de la Petite Ceinture parisienne (F)

La Petite Ceinture parisienne, voie de chemin de fer laissée à elle-même, est réinvestie par la mobilité douce. Si la continuité linéaire du rail est conservée, les espaces qu'elle traverse sont, quant à eux, loin d'être homogènes. La perception de la vill ...

Graphs That Admit Polyline Drawings with Few Crossing Angles

Radoslav Fulek

We consider graphs that admit polyline drawings where all crossings occur at the same angle alpha is an element of (0, pi/2]. We prove that every graph on n vertices that admits such a polyline drawing with at most two bends per edge has O(n) edges. This r ...

A new method for internal-external rotation measurement in a prosthetic knee

Kamiar Aminian, Arash Arami

In this work, a magnetic measurement system was designed and tested to estimate the Internal-External rotation between the Tibial and Femural parts of a knee prosthesis. To obtain this, the sensors were inserted in polyethylene part while a permanent magne ...

Measurement of Multi-segment Foot Joint Angles During Gait Using a Wearable System

Kamiar Aminian, Julien Favre, Xavier Crevoisier, Hossein Rouhani

Usually the measurement of multi-segment foot and ankle complex kinematics is done with stationary motion capture devices which are limited to use in a gait laboratory. This study aimed to propose and validate a wearable system to measure the foot and ankl ...

A Comparison Between Joint Coordinate System and Attitude Vector for Multi-segment foot Kinematics

Kamiar Aminian, Julien Favre, Xavier Crevoisier, Hossein Rouhani

The joint angles of multi-segment foot models have been primarily described using two mathematical methods: the joint coordinate system and the attitude vector. This study aimed to determine whether the angles obtained through these two descriptors are com ...

Comment on “Encoding many channels on the same frequency through radio vorticity: first experimental test”

Julien Perruisseau-Carrier, Michele Tamagnone

We show that the public experiment held in Venice by Tamburini et al and reported in 2012 New J. Phys. 14 033001 can be regarded as a particular implementation of multiple-input-multiple-output (MIMO) communications and, therefore, has no advantages over e ...

Jet impact angle on chute downstream of aerator

Michael Pfister

Chute aerators protect spillways from cavitation damage. Several parameters affect their efficiency, which were intensively discussed in literature. One implicit parameter is the cavity jet impact angle at the re-attachment point of the flow on the chute b ...

Corner Effect and Local Volume Inversion in SiNW FETs

Mihai Adrian Ionescu, Kirsten Emilie Moselund, Luca De Michielis, Luca Selmi

In this paper, a quantitative study of the corner effect and of the local volume inversion on gate-all-around MOSFETs based on numerical simulations has been carried out; different angles and doping levels are compared, in order to understand the impact of ...

Motion of Spin Polariton Bullets in Semiconductor Microcavities

Timothy Chi Hin Liew

The dynamics of optical switching in semiconductor microcavities in the strong coupling regime is studied by using time-and spatially resolved spectroscopy. The switching is triggered by polarized short pulses which create spin bullets of high polariton de ...
