Abstract:

With the introduction of a computational design environment, architectural design and representation processes witness a radical transition from the analog to the digital medium, that may be asserted to initiate a paradigm shift affecting both. In this new design environment, extending the instrumentality of computer-aided processes to the generative use of computational tools and procedures, architectural design and representation processes are subject to mutual alterations, challenged with computational design strategies such as parametric design, associative geometry, generative diagrams, s

Abstract:

Wave resource assessment is the collection of site-specific meteorological data to estimate the wave potential in a region and is carried out to mitigate the risks involved in the setup of wave energy converters. Wave resource assessment has been typically done using wave buoys. But wave buoys are expensive and require constant maintenance for smooth operation. An alternative to wave buoys is numerical wave modelling. Numerical wave modelling uses mathematical models to generate computer simulations that describe wave parameters in a region. This project is carried out in the region of Hvide S

It can be used as a guidance on how to model an area of interest, find the optimum location for micro wind turbines installation and calculate the annual energy production, commenting on the accuracy that can be expected from the results. Essentially, it is composed of three parts, each one deals with different set of tasks associated with model development and simulation. The first part investigates the computational practices

Unlike wind energy, however, the tides are predictable and thus tidal turbines could provide a reliable contribution of renewable energy to meet national energy demands. In 2

The blockage effect due to the presence of wind tunnel walls represents a big obstacle to the accuracy of the acquired data during testing. The flow constriction around the model depends primarly on wind tunnel dimensions and shape of the tested model. In this thesis, a numerical study of the correlation between a change in vehicle length and wind tunnel blockage effect is performed on a simple car model known as Ahmed body. To do that, two case scenarios are simulated: an open case, used as reference for the comparison, and a wind tunnel case, to simulate the effects of blockage. A compa

The current methods of damage prediction do not, in general, take into account the stiffness and weight of the surface structure. The model addresses this deficiency by explicit inclusion of the structure. Three-dimensional finite elements are used to model the ground with a non-linear, elasto-plastic soil model based on kinematic hardening.

Cortical bone is the hard and dense outer layer of bone, which holds majority of the load bearing capacity. Trabecular bone is the porous internal bone, which distributes loads at joints by allowing for a larger bearing surface and acts as an energy absorber. Trabecular bone has a complex, heterogeneous, anisotropic open cell lattice structure with a large variation in mechanical properties across anatomic site, species, sex, age, normal loading direction and disease state.

Abstract:

Les glissements de terrain sismo-induits sont des effets secondaires fréquents des séismes qui peuvent provoquer des dommages plus importants que les séismes eux-mêmes. Prévoir ces phénomènes est donc essentiel pour la gestion des risques dans les régions sismiques. Les déplacements co-sismiques sont généralement évalués par la méthode « bloc rigide » de Newmark (1965). Malgré ses limites, cette méthode a deux avantages: i) des temps de calcul relativement courts, ii) une compatibilité avec les logiciels SIG pour des analyses à l'échelle régionale. Les modélisations numériques complexes permet

Abstract:

The design and development of large scale seals, under a variety of loads and how they can be monitored for fault diagnosis and life prediction, have been investigated in this study. The work builds upon ideas of developing a physically based mathematical model of an elastomeric lip seal. The approach utilised finite element analysis to simulate its in-service operating condition, in order to obtain parameters needed to be considered for credible life performance of such seal, and therefore allow an extension for new large scale problems, in which the application can be used under increased lo

Abstract:

Die Quantenschlüsselverteilung (QKD), die erste anwendbare Quantentechnologie, verspricht informationstheoretisch sichere Kommunikation. In der vorliegenden Arbeit wurde das Zeit-Frequenz (TF)-QKD-Protokoll untersucht, das Zeit und Frequenz, nämlich Puls-Positionsmodulation (PPM) im Zeitbereich und Frequenzumtastung (FSK) im Frequenzbereich als die beiden komplementären Basen verwendet. Seine Sicherheit beruht den Quanteneigenschaften von Licht und auf der Zeit-Frequenz-Unschärferelation. TF-QKD kann mit größtenteils Standard-Telekommunikationstechnologie im 1550-nm-Band implementiert werd

Abstract:

Le turbomacchine elaborano spesso flussi contaminati da particelle solide. Nella maggior parte dei casi, la presenza di particelle micrometriche disperse nel fluido non è desiderata ed è correlata alle condizioni in cui la macchina opera. Questo è il caso di motori aeronautici, che, aspirando grandi quantità di aria ingeriscono significative quantità di particelle solide. In altri casi, le macchine a fluido sono progettate proprio con lo scopo di processare aria contaminata da particelle. Questo è infatti il caso di ventilatori centrifughi di grande taglia impiegati in impianti di produzione,

Abstract:

Face aux pénuries d'énergie et à la pollution croissante, de nombreux pays élaborent des politiques pour remplacer les combustibles fossiles par des sources d'énergie alternatives propres. Le stockage et le transport sont cruciaux dans la filière hydrogène. La compression et la liquéfaction sont courantes, le LH2 étant privilégié pour le transport moyen-long grâce à sa densité élevée. Cependant, les fuites peuvent provoquer incendies et explosions. Des centaines d'accidents, dont certains graves, ont été enregistrés. Afin d'étudier le comportement du LH2 lors de fuites accidentelles et d'améli

Abstract:

A child’s executive function (aspects: working memory, response inhibition, and set-shifting between sets of rules) capabilities have been found to strongly relate to their mathematics skills. However, while the relationship has been strongly supported by researchers, a consensus has not been reached regarding the specifics of the relationship between executive function and math skills, including which executive function aspect is most predictive of mathematical performance and the differences in said relationship that might be found when examining both numeracy, such as counting skills and ba
