    précise des variables d entrée la robustesse du modèle boîte noire global vis à vis des erreurs de modélisation de chaque système la connaissance de la distribution statistique de la réponse du modèle global peut on déterminer un domaine dans lequel la réponse du modèle peut être utilisée avec un certain degré de confiance la représentation des dépendances entre les sources d incertitudes sur les paramètres d entrée souvent interdépendantes pour des raisons physiques ou pratiques mais modélisés de manière simpliste par des variables indépendantes ou des corrélations linéaires La mise en place de tels outils constituerait une avancée importante vers la conception robuste de systèmes complexes et ainsi la maîtrise des risques liés à la modélisation Cette tâche vise à développer des outils mathématiques avancés pour modéliser de manière générique des systèmes en interaction L aspect particulièrement innovant est le cas de systèmes complexes tel que des codes numériques du type éléments finis Les travaux s articuleront autour des deux étapes suivantes Les points particuliers suivants se trouvent d emblée au centre de la problématique Deux stratégies sont opposables agrégation des modèles boîtes noires des systèmes modélisation boîte noire du système global Caractérisation statistique des sorties du modèle comportemental estimation de la densité de probabilité des sorties problème de propagation de l incertitude caractérisation des valeurs extrêmes etc Dans un deuxième temps on étudiera la sensibilité du modèle global vis à vis des incertitudes de chaque système Afin de prendre en compte l incertitude sur chacun des systèmes en interaction liée entre autres aux erreurs de modèles et à la méconnaissance des variables entrant en jeu plusieurs stratégies peuvent être envisagées Une première approche serait d étudier théoriquement l influence des différentes sources d incertitude sur la distribution statistique de la réponse du modèle global Une autre approche serait de propager les incertitudes des différents systèmes à travers leur mise en interaction par des méthodes classiques du type simulations Monte Carlo ou issues de la fiabilité des structures Sur le volet dépendances plusieurs pistes existent dans la littérature et que l on expérimentera de façon plus avancée sur des exemples la mise en place d un modèle dédié de copule l estimation d une loi jointe dans un cadre bayésien ou encore le raffinement d une couche de modélisation physique sous jacente expliquant les dépendances On tirera notamment partie des capacités de simulation haute performance nécessaires pour les calculs associés Les travaux prendront la forme d une thèse en collaboration entre Supélec et l ECP qui touchera les domaines scientifiques variés Probabilités et statistiques simulation numérique optimisation et contrôle approximation des fonctions Les caractéristiques particulières liées aux problématiques industrielles seront prises en compte en amont par le WP1 et au fil des développements théoriques En plus de la fourniture théorique qui prendra la forme de publications l objectif du projet est la fourniture de prototypes sous la forme de briques logicielles en méta langage du type R ou Scilab L efficacité des méthodes développées sera démontrée sur des cas

  • WikiDeletePage – Opus Project
    page These buttons are only visible for users with WIKI DELETE permissions Note Deleting a wiki page is an irreversible operation In general it is recommended to create redirection pages instead of completely deleting an old page as to not frustrate the visitor with broken links when coming to the site from a search engine A redirection page is a short page that contains a link such as See SomeOtherPage

  • WikiHtml – Opus Project
    Use HTML To inform the wiki engine that a block of text should be treated as HTML use the html processor This example should explain html h1 style text align right color blue HTML Test h1 Results in HTML Test Note that Trac sanitizes your HTML code before displaying it That means that if you try to use potentially dangerous constructs such as Javascript event handlers those will be removed from the output Since 0 11 the filtering is done by Genshi and as such the produced out will be a well formed fragment of HTML In other words this mean that you can no longer use two HTML blocks one for opening a div the second for closing it in order to wrap arbitrary wiki text To achieve this you need now to use the div Wiki processor div class important style border 2pt solid text align center This is the only way to go in Trac 0 11 Results in This is the only way to go in Trac 0 11 For spans you should rather use the Macro call syntax Hello span WORLD click world anchor here style color green font size 120 id world anchor Results

    name start with the filters are output TracGuideToc This macro shows a quick and dirty way to make a table of contents for a set of wiki pages TicketQuery Macro that lists tickets that match certain criteria This macro accepts a comma separated list of keyed parameters in the form key value If the key is the name of a field the value must use the syntax of a filter specifier as defined in TracQuery QueryLanguage Note that this is not the same as the simplified URL syntax used for query links starting with a character In addition to filters several other named parameters can be used to control how the results are presented All of them are optional The format parameter determines how the list of tickets is presented list the default presentation is to list the ticket ID next to the summary with each ticket on a separate line compact the tickets are presented as a comma separated list of ticket IDs count only the count of matching tickets is displayed table a view similar to the custom query view but without the controls The max parameter can be used to limit the number of tickets shown defaults to 0 i e no maximum The order parameter sets the field used for ordering tickets defaults to id The desc parameter indicates whether the order of the tickets should be reversed defaults to false The group parameter sets the field used for grouping tickets defaults to not being set The groupdesc parameter indicates whether the natural display order of the groups should be reversed defaults to false The verbose parameter can be set to a true value in order to get the description for the listed tickets For table format only deprecated in favor of the rows parameter The rows parameter can be used to specify which field s should be viewed as a row e g rows description summary For compatibility with Trac 0 10 if there s a second positional parameter given to the macro it will be used to specify the format Also using as a field separator still works but is deprecated TracAdminHelp Displays help for trac admin commands Examples TracAdminHelp all commands TracAdminHelp wiki all wiki commands TracAdminHelp wiki export the wiki export command TracAdminHelp upgrade the upgrade command WikiCalendar Inserts a small calendar where each day links to a wiki page whose name matches wiki page format The current day is highlighted and days with Milestones are marked in bold This version makes heavy use of CSS for formatting Tested in Firefox 2 0 only Usage WikiCalendar year month show buttons wiki page format Arguments year 4 digit year defaults to current year month 2 digit month defaults to current month show buttons boolean defaults to true wiki page format string defaults to Y m d Examples WikiCalendar 2006 07 WikiCalendar 2006 07 false WikiCalendar true Meeting Y m d WikiCalendar 2006 07 false Meeting Y m d NewsFlash Makes a colored box
