URI http://ori.unit-c.fr/uid/unit-ori-wf-1-5611 Introduction to Data Assimilation for Scientists and Engineers eng Data assimilation is the meeting point of physical modelling, uncertainty analysis and mathematical algorithm. Given measurements with error and considering that modelling cannot be exact, the purpose of data assimilation is to mix these different sources of information with the proper weighting. Engineer applications based on modelling are making a grow use of data assimilation techniques with the increase of quantitative informations on the physical system. The present course provides a basic introduction to data assimilation with the point of view of practical applications. It is organized with the following chapters: -From weather forecast to engineer applications: basic ideas on data assimilation are presented on several example, starting with weather forecast - Three simple examples of data assimilation: estimations of clock time, hydraulic jump velocity or tank filling parameters are used for hands on - Some classical data assimilation methods: opening towards real applications methods are hinted data assimilation assimilation de données méthode d'optimisation variational analysis systems cost function Best Linear Unbiased Estimation 4D-Var method four-dimensional variational assimilation optimal interpolation weather forecast météorologie LOMv1.0 linear LOMv1.0 3 LOMv1.0 son LOMv1.0 image LOMv1.0 ressource interactive LOMv1.0 author BEGIN:VCARD VERSION:3.0 N:Thual;Olivier;;; FN:Olivier Thual EMAIL;TYPE=INTERNET:thual@imft.fr ORG:Institut National Polytechnique de Toulouse END:VCARD 2013-02-02 LOMv1.0 publisher BEGIN:VCARD VERSION:3.0 N:INP Toulouse;;;; FN:INP Toulouse EMAIL;TYPE=INTERNET: ORG:Institut National Polytechnique de Toulouse END:VCARD 2013-02-02 URI http://ori.unit-c.fr/uid/unit-ori-wf-1-5612 LOMv1.0 validator BEGIN:VCARD VERSION:3.0 N:Duranton;Sylvain;;; FN:Sylvain Duranton ORG:UNIT URL:http://www.univ.fr UID:sduranton EMAIL;TYPE=INTERNET: END:VCARD LOMv1.0 creator BEGIN:VCARD VERSION:3.0 N:Thual;Olivier;;; FN:Olivier Thual ORG:Institut National Polytechnique de Toulouse URL:http://www.univ.fr UID:othual EMAIL;TYPE=INTERNET: END:VCARD LOMv1.0 LOMFRv1.0 SupLOMFRv1.0 text/html http://pedagotech.inp-toulouse.fr/130202 LOMv1.0 lecture LOMv1.0 exercise SupLOMFRv1.0 liste de références LOMv1.0 learner LOMv1.0 higher education PT6H eng LOMv1.0 no LOMv1.0 yes Creative Commons Attribution - Partage dans les Mêmes Conditions 3.0 non transposé (CC BY-SA) LOMv1.0 discipline Classification UNIT 1206 Optimisation mathématique, optimisation des structures CDD 22e éd. 519.6 Optimisation mathématique
