Although Bayesian Networks (BNs) are increasingly being used to solve real world problems [47], their use is still constrained by the difficulty of constructing the node probability tables (NPTs). A key challenge is to construct relevant NPTs using the minimal amount of expert elicitation, recognising that it is rarely cost-effective to elicit complete sets of probability values. This thesis describes an approach to defining NPTs for a large class of commonly occurring nodes called ranked nodes. This approach is based on the doubly truncated Normal distribution with a central tendency that is invariably a type of a weighted function of the parent nodes. We demonstrate through two examples how to build large probability tables using the ranked nodes approach. Using this approach we are able to build the large probability tables needed to capture the complex models coming from assessing firm's risks in the safety or finance sector. The aim of the first example with the National Air-Traffic Services(NATS) is to show that using this approach we can model the impact of the organisational factors in avoiding mid-air aircraft collisions. The resulting model was validated by NATS and helped managers to assess the efficiency of the company handling risks and thus, control the likelihood of air-traffic incidents. In the second example, we use BN models to capture the operational risk (OpRisk) in financial institutions. The novelty of this approach is the use of causal reasoning as a means to reduce the uncertainty surrounding this type of risk. This model was validated against the Basel framework [160], which is the emerging international standard regulation governing how financial institutions assess OpRisks.

L'impulsion est une phase déterminante de la performance sportive. Ce travail s'intéresse ainsi à la mesure indirecte par l'acquisition de mouvements, des forces mises en jeu lors de la phase de contact avec le sol. Cette mesure fait généralement intervenir les tables anthropométriques basées sur des moyennes. Ce travail cherche à individualiser les paramètres segmentaires plutôt que d'utiliser ces tables. La résultante des forces ainsi déterminée est modélisée par des splines cubiques permettant la comparaison de son évolution. Pour cela, on utilise des paramètres qui prennent en compte la forme de la courbe. Ces deux techniques sont utilisées pour permettre la simulation de nouvelles impulsions. Cette simulation repose sur l'adaptation de nouveaux mouvements à partir d'impulsions déjà acquises. Les points caractéristiques qui modélisent l'impulsion sont alors optimisés pour adapter la performance à de nouvelles contraintes.

Αντικείμενο της παρούσας διπλωματικής εργασίας είναι η ανάλυση του δείγματος των ερωτηματολογίων ως εργαλείο μελέτης των παραγόντων που σχετίζονται μεταξύ τους και επηρεάζουν σημαντικά στην ίδρυση μιας μικρομεσαίας επιχείρησης. Το είδος και η μορφή των ερωτήσεων, μας οδηγούν αρχικά να διερευνήσουμε τις μεταβλητές μας μέσω πινάκων συνάφειας, καθώς οι εμπλεκόμενες μεταβλητές είναι κυρίως κατηγορικές. / The topic of the present thesis is, at a first stage, the evaluation of those questionnaires on the whole, as a tool of the study of the factors that may affect the establishment of a small and medium-sized enterprise. The type and the form of the questions initially lead us to introduce mainly categorical variables (nominal or ordinal) and to cross-classify them, forming thus contingency tables.

A systematic study of the excess thermodynamic properties of two-ring compounds and n-alkanes was conducted. The excess enthalpies were determined at 288,15 K and 298,15 K by using a flow microcalorimetric technique. The excess volumes of tetralin and cycloalkanes, and tetralin and --alkans at 288,15 K and 298,15 K were determined by using a vibrating tube densitometer. The results showed trends relating to the size and shape of the n-alkane and cycloalkan molecules. The theory developed by Flory was applied to the decalin + cycloalkane and + n-alkane systems and this gave qualitative predictions of the excess enthalpies from the excess volumes and vice versa. / KMBT_363 / Adobe Acrobat 9.53 Paper Capture Plug-in
