Turning a conventional camera into a 3D camera with an add-on.

We propose to add an optical component in front of a conventional camera to improve depth estimation performance of depth from defocus (DFD), an approach based on the relation between defocus blur and depth. The add-on overcomes ambiguity and the dead zone, which are the fundamental limitations of DFD with a conventional camera, by adding an optical aberration to the whole system that makes the blur unambiguous and measurable for each depth. We look into two optical components: the first one adds astigmatism and the other one chromatic aberration.

[Care for young children who have suffered a tragic event].

Children are regularly faced with traumatic events, whether these are disasters (tsunami, floods, earthquakes), accidents (transport, domestic) or intentional acts (war, ill treatment). The care provided for young Haitian children following the earthquake in January 2010 offers an insight into specific intervention methods, the treatment of post-traumatic disorders and the effects of trauma on those working with them.

[Immediate intervention of medico-psychological emergency units].

Medico-psychological emergency units (CUMP) are part of the emergency medical assistance services. They are adapted to the early treatment of people suffering from the psychological effects of an intentional or accidental disaster. Immediate intervention implies the rapid setting up of a system adapted to the context and to the clinic.

Mie potentials for phase equilibria calculations: application to alkanes and perfluoroalkanes.

Transferable united-atom force fields, based on n - 6 Lennard-Jones potentials, are presented for normal alkanes and perfluorocarbons. It is shown that by varying the repulsive exponent the range of the potential can be altered, leading to improved predictions of vapor pressures while also reproducing saturated liquid densities to high accuracy. Histogram-reweighting Monte Carlo simulations in the grand canonical ensemble are used to determine the vapor liquid coexistence curves, vapor pressures, heats of vaporization, and critical points for normal alkanes methane through tetradecane, and perfluorocarbons perfluoromethane through perfluorooctane.
