Evaluation des sequelles chez les victimes dâaccidents de la circulation
La loi n°2005-86 du 15 aoĂ»t 2005 a dĂ©fini les prĂ©judices indemnisables suite Ă un accident de la circulation: les frais de soins imputables Ă lâaccident, la perte de revenus durant la pĂ©riode dâincapacitĂ© temporaire de travail, lâincapacitĂ© permanente partielle, le prĂ©judice moral et esthĂ©tique, les frais dâassistance dâune tierce personne, le prĂ©judice Ă©conomique, le prĂ©judice moral et les frais funĂ©raires en cas de dĂ©cĂšs. Nous proposons une mĂ©thodologie dâĂ©valuation de ces diffĂ©rents chefs de prĂ©judice notamment les incapacitĂ©s en otorhino- laryngologie.Mots clĂ©s : Expertise, Dommage corporel.The law n°2005-86 of 15 August 2005, defined prejudices to indemnify after a road accident: care expenses due to the accident, loss of incomes during the period of temporary inability of work, partial permanent inability, moral and aesthetic prejudice, expenses of assistance by a third person, economic prejudice, moral prejudice and funeral expenses in case of death. We propose a methodology of assessment of these different chiefs of prejudice, notably in otorhinolaryngology inabilities.  Key words: Expertise, Bodily damage
Inviscid incompressible limits of the full Navier-Stokes-Fourier system
We consider the full Navier-Stokes-Fourier system in the singular limit for
the small Mach and large Reynolds and Peclet numbers, with ill prepared initial
data on the three dimensional Euclidean space. The Euler-Boussinesq
approximation is identified as the limit system
Uniform regularity for the Navier-Stokes equation with Navier boundary condition
We prove that there exists an interval of time which is uniform in the
vanishing viscosity limit and for which the Navier-Stokes equation with Navier
boundary condition has a strong solution. This solution is uniformly bounded in
a conormal Sobolev space and has only one normal derivative bounded in
. This allows to get the vanishing viscosity limit to the
incompressible Euler system from a strong compactness argument
A bio-inspired image coder with temporal scalability
We present a novel bio-inspired and dynamic coding scheme for static images.
Our coder aims at reproducing the main steps of the visual stimulus processing
in the mammalian retina taking into account its time behavior. The main novelty
of this work is to show how to exploit the time behavior of the retina cells to
ensure, in a simple way, scalability and bit allocation. To do so, our main
source of inspiration will be the biologically plausible retina model called
Virtual Retina. Following a similar structure, our model has two stages. The
first stage is an image transform which is performed by the outer layers in the
retina. Here it is modelled by filtering the image with a bank of difference of
Gaussians with time-delays. The second stage is a time-dependent
analog-to-digital conversion which is performed by the inner layers in the
retina. Thanks to its conception, our coder enables scalability and bit
allocation across time. Also, our decoded images do not show annoying artefacts
such as ringing and block effects. As a whole, this article shows how to
capture the main properties of a biological system, here the retina, in order
to design a new efficient coder.Comment: 12 pages; Advanced Concepts for Intelligent Vision Systems (ACIVS

Stability with respect to domain of the low Mach number limit of compressible viscous fluids
We study the asymptotic limit of solutions to the barotropic Navier-Stokes
system, when the Mach number is proportional to a small parameter \ep \to 0
and the fluid is confined to an exterior spatial domain \Omega_\ep that may
vary with \ep. As , it is shown that the fluid
density becomes constant while the velocity converges to a solenoidal vector
field satisfying the incompressible Navier-Stokes equations on a limit domain.
The velocities approach the limit strongly (a.a.) on any compact set, uniformly
with respect to a certain class of domains. The proof is based on spectral
analysis of the associated wave propagator (Neumann Laplacian) governing the
motion of acoustic waves.Comment: 32 page
Suicide Among Adolescents in Center Tunisia: An 18-Year Autopsy Study
Background: Suicide and suicide attempts are more common among adolescents. Many factors are known to influence suicide in particular: region and culture. Adolescent suicide has been widely studied in many countries, but there are, currently, no data relating to adolescent suicide in Tunisia. Aim: The aims of this study were to describe epidemiological aspects of death related to adolescent suicide in Sousse, a city in central Tunisia. Methods: Data of forensic autopsies from 1998 to 2015 related to suicide of adolescents were retrospectively examined considering age, gender, method of death, year and risk factor. Results: 70 cases were reported with female predominance (62, 8%). The age range was from 10 to 19 and most of the suicides occurred in the 15-to-19 age group (75, 7%). Most victims were from rural zones (70%). Self-poisoning was the most used method (47, 1 %) followed by hanging (35, 7%). Hanging was the most common method used by males (17/26) and self-poisoning by females (29/44). Self-poisoning was related to pesticides in the vast majority of cases (29 cases among 33). The identified precipitating factors were chronic family problems in 51.4%, sentimental deception in 8.6%. Conclusion: This retrospective study raises concerns regarding the use of pesticides and the urgent need to provide rural areas with structures and medical equipment. This will ensure adequate suicide prevention in the region
Vanishing Viscous Limits for 3D Navier-Stokes Equations with A Navier-Slip Boundary Condition
In this paper, we investigate the vanishing viscosity limit for solutions to
the Navier-Stokes equations with a Navier slip boundary condition on general
compact and smooth domains in . We first obtain the higher order
regularity estimates for the solutions to Prandtl's equation boundary layers.
Furthermore, we prove that the strong solution to Navier-Stokes equations
converges to the Eulerian one in and
L^\infty((0,T)\times\o), where is independent of the viscosity, provided
that initial velocity is regular enough. Furthermore, rates of convergence are
obtained also.Comment: 45page
On the existence of solutions to the relativistic Euler equations in 2 spacetime dimensions with a vacuum boundary
We prove the existence of a wide class of solutions to the isentropic
relativistic Euler equations in 2 spacetime dimensions with an equation of
state of the form that have a fluid vacuum boundary. Near the fluid
vacuum boundary, the sound speed for these solutions are monotonically
decreasing, approaching zero where the density vanishes. Moreover, the fluid
acceleration is finite and bounded away from zero as the fluid vacuum boundary
is approached. The existence results of this article also generalize in a
straightforward manner to equations of state of the form

Dynamical elastic bodies in Newtonian gravity
Well-posedness for the initial value problem for a self-gravitating elastic
body with free boundary in Newtonian gravity is proved. In the material frame,
the Euler-Lagrange equation becomes, assuming suitable constitutive properties
for the elastic material, a fully non-linear elliptic-hyperbolic system with
boundary conditions of Neumann type. For systems of this type, the initial data
must satisfy compatibility conditions in order to achieve regular solutions.
Given a relaxed reference configuration and a sufficiently small Newton's
constant, a neigborhood of initial data satisfying the compatibility conditions
is constructed
Tests of concrete flanged beams reinforced with CFRP bars.
yesTests results of three flanged and two rectangular cross-section concrete beams reinforced with carbon fibre reinforced polymer (CFRP) bars are reported. In addition, a companion concrete flanged beam reinforced with steel bars is tested for comparison purposes. The amount of CFRP reinforcement used and flange thickness were the main parameters investigated in the test specimens. One CFRP reinforced concrete rectangular beam exhibited concrete crushing failure mode, whereas the other four CFRP reinforced concrete beams failed due to tensile rupture of CFRP bars. The ACI 440 design guide for FRP reinforced concrete members underestimated the moment capacity of beams failed due to CFRP tensile rupture and reasonably predicted deflections of the beams tested.
A simplified theoretical analysis for estimating the moment capacity of concrete flanged beams reinforced with FRP bars was developed. The experimental moment capacity of the CFRP reinforced concrete beams tested compared favourably with that predicted by the theoretical analysis developed
