Titre du sujet : Optimisation de structures a�ronautiques : une nouvelle
m�thode
� fid�lit� adaptative
Responsables :
Christian Gogu  ( christian.gogu at univ-tlse3.fr

Description du sujet :

L'optimisation de structures est un des enjeux majeurs pour l'ensemble
des industries
m�caniques � forte valeur ajout�e (a�ronautique, spatial, automobile
...) car elle permet
d'am�liorer les performances et les fonctionnalit�s d'un produit dans un
contexte de
comp�tition accrue. Un verrou scientifique majeur dans le d�veloppement
de m�thodes
d'optimisation des structures r�side dans la gestion des temps de calcul
afin de rendre
ces m�thodes utilisables dans l'industrie. L'emploi de m�tamod�les a
rendu possible
de nombreuses m�thodes d'optimisation � co�t r�duit. N�anmoins
il est
important de
maitriser la qualit� du m�tamod�le afin de contr�ler la
pr�cision des
analyses d'optimisation.
Ce constat a donn� lieu � des m�thodes s�quentielles adaptatives qui
utilisent la structure
d'incertitudes du krigeage (un type particulier de m�tamod�le) afin de
raffiner la pr�cision
des �valuations de l'optimisation en fonction des besoins du probl�me
(m�thodes types
EGO [1]). Ces m�thodes s�quentielles peuvent toutefois rester encore
trop co�teuses en
temps de calculs.

Une nouvelle m�thode de construction de m�tamod�les a �t�
r�cemment
d�velopp�e
dans l'�quipe [2], permettant de construire le m�ta-mod�le de mani�re
adaptative en
utilisant un nombre notablement r�duit de simulations. Le couplage de
cette approche
avec l'optimisation s�quentielle de type EGO dans une nouvelle m�thode
d'optimisation
de structures � fid�lit� adaptative offre un potentiel de
r�duction des
temps de calculs
de plusieurs ordres de grandeur. Le d�veloppement et l'impl�mentation de
cette nouvelle
m�thode feront l'objet de cette th�se. Une application � l'optimisation
d'un caisson de
voilure sera impl�ment�e afin de valider les d�veloppements
m�thodologiques.

Ces travaux se d�rouleront en double coop�ration : d'une part avec l'axe
MS2M-ISS
(J.C. Passieux) de l'ICA pour l'aspect mod�lisation adaptative, d'autre
part avec le Prof.
Raphael Haftka de l'Universit� de Floride, expert mondial en m�thodes
d'optimisation
de structures. Un s�jour de l'�tudiant � l'Universit� de Floride est
envisageable.

2- Postdoctoral Research Position in Optimization at UW-Madison
(source: M. Th�ra)


We are seeking a postdoc with interests in Optimization to join our
group in the
Wisconsin Institute for Discovery (WID) at the University of
Wisconsin-Madison
(www.discovery.wisc.edu). WID is the public half of an exciting
public-private pair
of Institutes that will promote basic research and facilitate the
translation of new
discoveries to practice.

The WID optimization theme aims to develop and apply optimization technology
to systems-level problems emerging in science and engineering
applications in an
interdisciplinary, integrative, and collaborative fashion.
Collaborations with
agricultural economics and energy systems researchers will be a focus.
Our interests
encompass (but are not limited to): (i) Development of core optimization
technology
and large scale computational methodology; (ii) Planning techniques for
integrated
modeling that exploit understanding of the physical system; (iii)
Application and
development of simulation and stochastic optimization techniques; (iv)
Use of
optimization and statistical methods to understand and predict systems
phenomena,
even when competition exists between entities; (v) Sparse optimization
and image
reconstruction leveraging compressed sensing frameworks, optimization
algorithms,
and powerful computational platforms.

Possible faculty members you may work with include:
Prof. C. DeMarco,

8- Workshop on Shape Optimization, September 23-27, Erlangen
(source: A. Pratelli)


We are organizing a Workshop on "New Trends in Shape Optimization", to
be held
in Erlangen on September 23-27, 2013: you can find all the relevant
informations
at the webpabe
www.math.fau.de/shapeopt.

The workshop aims at putting together people which are mainly interested
either
in the more "analytical", or in the more "numerical" point of view. In
particular,
there will be 10 plenary conferences, and two parallel sessions with a
number of
talks more specialized in one of the two main topics.
The plenary speakers are Buttazzo, Bucur, Delfour, Freitas, Henrot,
Hinterm�ller,
Schulz, Sethian, Sokolowski, Van den Berg.

There is a number of grants available for covering the hotel expenses of
Ph.D. or
Postdocs students. Young stundents can also send a proposal for short
talks.

We hope that you are interested in this workshop, and we would be
grateful if you
could spread the news among all your potentially interested students or
colleagues.

You can write us (also at the workshop email address, which is
shapeopt at math.fau.de)
for any request of further information. Thank you very much for your
interest, and
sorry for multiple posting.

9- Master Recherche RO (M2R RO) toulousain
(source: M. Mongeau)


Le Master Recherche RO (M2R RO) toulousain a d�marr� en septembre
dernier, suite � une forte demande r�gionale des industriels pour des
ing�nieurs comp�tents en Recherche Op�rationnelle (RO).

Le M2R RO est g�r� par l'ENAC et la majorit� des cours propos�s sont
mutualis�s avec des cours de derni�re ann�e des �coles d'ing�nieurs
toulousaines : ENAC, INSA, ISAE et ENSEEIHT. Formellement, cette
formation est un des parcours du M2R toulousain Informatique &
T�l�communications port� par l'Universit� Paul Sabatier.

Le M2R RO est adoss� au groupe informel de recherche toulousain TORO
http://www.toro-toulouse.fr/ et b�n�ficie d'un partenariat privil�gi�
avec Montr�al. En plus d'�tre un des principaux centres mondiaux de
recherche et de formation dans le domaine de la RO, Montr�al est la 3e
capitale de l'a�ronautique (si�ge de Bombardier, de l'OACI et de
l'AITA), en phase avec la couleur a�ronautique du M2R RO toulousain.

De nombreux ing�nieurs/chercheurs de l'industrie et des services (Airbus,
Air France, Altran, Amadeus, Bouygues, Cap Gemini, EdF, Eurodecision,
Google, IBM, Orange Labs, Renault, SNCF, Total) soutiennent le M2R RO
toulousain -- lire leurs t�moignages sous l'onglet � D�bouch�s �
du site
web du M2R RO :http://m2rit-ro.recherche.enac.fr/.

Les inscriptions pour la rentr�e 2013 sont ouvertes jusqu'au 12 juin
(tous les d�tails sur ce m�me site web).
