Abstract:
<p>This master’s thesis examines the possibility to heuristically optimise instruction cache performance in a Just-In-Time (JIT) compiler. </p><p>Programs that do not fit inside the cache all at once may suffer from cache misses as a result of frequently executed code segments competing for the same cache lines. A new heuristic algorithm LHCPA was created to place frequently executed code segments to avoid cache conflicts between them, reducing the overall cache misses and reducing the performance bottlenecks. Set-associative caches are taken into consideration and not only direct mapped cache

Cópulas tem se tornado uma importante ferramenta para descrever e analisar a estrutura de dependência entre variáveis aleatórias e processos estocásticos.

The role of dioxolane oxygen was inferred from studies with a hydrocarbon model system. The effect of cyclohexene ring conformation on the diastereoselectivity was examined for confo

Dans cette these, nous proposons de travailler sur la classe des fonctions aleatoires stables pour la modelisation et simulation de variables regionalisees. Dans la premiere partie, nous abordons le probleme de la realisation d'une fonction de covariance. Nous proposons deux methodes permettant d'une part d'etablir, par une nouvelle approche, les principaux resultats concernant les processus auttoregressifs a moyennes mobiles et d'autre part de calculer les parametres associes. Enfin, nous abordons le probleme de la simulation conditionnelle pour lequel nous proposons une solution directe en v

L’objectif de cette thèse est d’analyser le comportement de la décomposition modale empirique (EMD) et sa version multivariée (MEMD) dans le cas de processus stochastiques : bruit Gaussien fractionnaire (fGn) et processus symétrique alpha stable (SαS). Le fGn est un bruit large bande généralisant le cas du bruit blanc Gaussien et qui trouve des applications dans de nombreux domaines tels que le trafic internet, l’économie ou le climat. Par ailleurs, la nature «impulsive» d’un certain nombre de signaux (craquement des glaces, bruit des crevettes claqueuses, potentiel de champ local en neuroscie

Abstract:
Accurate estimation of environmental dose rate is essential for high-resolution trapped-charge dating. Beta and gamma emissions from simulated sediments containing radioactive uranium, thorium and potassium are modelled in contexts that are spatially heterogeneous. Dose rate was modelled using Monte Carlo radiation transport codes MCNP and PENELOPE. A number of key issues that affect dose rate evaluation are examined and updated corrections are calculated. Granular structures used for geometrical input into the models were simulated using randomly packed ellipsoids. The pair correlation functi

Il Laboratorio PQAT dell’IQS School of Engineering lavora come ente valutatore delle analisi del rischio e delle analisi quantitative del rischio che gli stabilimenti chimici situati nel territorio catalano e soggetti alla normativa Seveso presentano alla Generalitat de Catalunya. Le analisi del rischio sono importanti ai fini della protezione della popolazione mentre le analisi quantitative del rischio sono utilizzate nella pianificazione territoriale. Nel procedimento di valutazione si realizzano differenti fasi di calcolo, alcune operate manualmente altre attraverso l’utilizzo di software.

Abstract:
INTRODUÇÃO: Os hepatócitos apresentam papel potencial em iniciar e amplificar a resposta inflamatória aguda no fígado, através da liberação de citocinas pró-inflamatórias, em papel complementar ao exercido pelas células de Kupffer e endoteliais. A invasão bacteriana da célula hepática é um estímulo para que o hepatócito produza citocinas como o TNF-alfa, capaz de induzir sua própria morte por apoptose. O TNF-alfa pode ser tanto um agente citotóxico (induzindo a morte celular), quanto um agente protetor (através da ativação de NF-kB). A morte por apoptose do hepatócito libertaria as bactérias q

Abstract:
Dans cette thèse on s'intéresse au temps local d'auto-intersections de marches aléatoires. Cette quantité est définie comme la norme-$p$ à la puissance $p$ du temps local de la marche. Elle regarde dans quelle mesure la trajectoire de la marche aléatoire s'intersecte. Le temps local d'auto-intersections est lié à différents modèles physiques comme les modèles de polymères ou les problèmes d'écoulements de flux en milieux stratifiés mais aussi au modèle mathématiques des marches aléatoires en paysages aléatoires. Nous nous sommes pour notre part intéressés en particulier aux grandes déviations

Les tumeurs ovariennes des cordons sexuels sont des tumeurs rares qui se développent aux dépens des cellules non germinales de l'ovaire. Depuis deux décennies l'individualisation des tumeurs juvéniles de la granulosa a constitué une avancée majeure dans le traitement de ces tumeurs de l'enfant. Cependant leur physiopathologie reste indéterminée. L'objectif de cette thèse est de rechercher dans ces tumeurs une éventuelle implication de la voie de la signalisation de la Gαs et une dysrégulation de l'expression des gènes de la détermination gonadique.

Abstract:
We introduce a simple tree growth process that gives rise to a new two-parameter family of discrete fragmentation trees that extends Ford's alpha model to multifurcating trees and includes the trees obtained by uniform sampling from Duquesne and Le Gall's stable continuum random tree. We call these new trees the alpha-gamma trees. In this thesis, we obtain their splitting rules, dislocation measures both in ranked order and in sized-biased order, and we study their limiting behaviour. We further extend the underlying exchangeable fragmentation processes of such trees into partly exchangeable f

Le mouvement brownien fractionnaire (mbf) constitue un important outil de modélisation utilisé dans plusieurs domaines (biologie, économie, finance, géologie, hydrologie, télécommunications, etc.) ; toutefois, ce modèle ne parvient pas toujours à donner une description suffisamment fidèle de la réalité, à cause, entre autres, des deux limitations suivantes : d'une part le mbf est un processus gaussien, et d'autre part, sa rugosité locale (mesurée par un exposant de Hölder) reste la même tout le long de sa trajectoire, puisque cette rugosité est partout égale au paramètre de Hurst H qui est une
