Abstract:

Even though there are no regulations on the interior noise level of passenger cars, it is a significant quality aspect both for customers and for car manufacturers. The reduction of many other car noise sources pushed tyre road noise to the forefront.What is more, well known phenomenon of the tyre acoustic cavity resonance (TCR), appearing around 225 Hz, makes the interior noise noticeably worse. Some techniques to mitigate this phenomenon right at the source are discussed in this thesis, however, these has not been adopted by the tyre nor car manufacturers yet.Therefore, there is a desire to

Abstract:

Diagnostic tests are designed to detect and isolate faults in sequential systems. The problem is to evaluate the effectiveness of the design. For stuck faults a diagnostic model can be used. A fault simulation strategy is presented for generating this model. First, definitions, for identifying critical inputs are derived. A definition is a statement of the conditions to sensitize an input. Then a fault free simulation is used to generate a critical value array. A critical path is traced through the sensitized inputs marked in the array using a critical value array tracing algorithm that is dev

Abstract:

Recent empirical assessments revealed that footprint indicators calculated with various multi-regional input-output (MRIO) databases deliver deviating results. In this paper, we propose a new method, called structural production layer decomposition (SPLD), which complements existing structural decomposition approaches. SPLD enables differentiating between effects stemming from specific parts in the technology matrix, e.g. trade blocks vs. domestic blocks, while still allowing to link the various effects to the total region footprint.

Delay and disruption (DD) to contractors’ progress, often resulting in time and cost overruns, are a major source of claims and disputes in the construction industry. At the heart of the matter in dispute is often the question of the extent of each contracting party’s responsibility for the delayed project completion and extra cost incurred. Various methodologies have been developed over the years as aids to answering this question. Whilst much has been written about DD, there is limited information on the extent of use of these methodologies in practice. The research reported in this thesis w

Abstract:

With advances in technology, modern integrated circuits have higher complexities and reduced transistor sizing. In deep sub-micron, the parameter variation-control is difficult and component delays vary from one manufactured chip to another. Therefore, the delays are not discrete values but are a statistical quantity, and statistical evaluation methods have gained traction. Furthermore, fault injection based gate-level fault coverage is non-scalable and statistical estimation methods are preferred.

The use of accelerators in heterogeneous systems is an established approach in designing petascale applications.

This work contributes by analyzing hybrid MPICUDA programs for properties based on wait states, such as the critical path, a metric proven to identify application bottlenecks effectively.

In particular, it allows to solve higher order Partial Differential Equations (PDEs) directly omitting the usage of mixed approaches.

However, these sensors are not selective for the pulp properties of interest. Therefore, advanced signal processing and multivariate calibration are essential tools.

Les entreprises pharmaceutiques ont progressivement adopté le concept de Process Analytical Technology (PAT) afin de contrôler et d'assurer en temps réel la qualité des produits pharmaceutiques au cours de leur production. Le PAT et un composant central du concept plus général de Quality-by-Design (QbD) promu par les agence régulatrices et visant à construire la qualité des produits via une approche scientifique et la gestion des risques.Une méthode basée sur la spectroscopie proche infrarouge (PIR) a été développée comme un outil du PAT pour contrôler en ligne la cristallisation d'un principe

Abstract:

L'un des moyens pour faire face à la réduction de l'utilisation d'intrants de synthèse est de favoriser durablement les services agro-écologiques de la diversité végétale. Pour cela, l'agriculteur devra adapter ses modes de gestion. Ma thèse s'inscrit dans l'objectif finalisé d'apporter à l'agriculteur, de l'aide à la gestion de cette diversité végétale sur le territoire de son exploitation. Je me suis fixé 2 objectifs de recherche : i) vérifier si les interchamps et le stock semencier constituent des sources d'espèces pour le centre des parcelles agricoles et ii) quantifier l'influence de la

Abstract:

La comparación de imágenes es un ingrediente fundamental en muchos problemas de procesamiento de imagen y visión por computador. Esta tesis aborda el problema de la comparación de entornos locales en imágenes, o patches, por medio de medidas de similitud (o funciones distancia). En particular, estudiamos el problema de la comparación invariante afín de imágenes a partir de sus patches, lo cual abre la puerta a un análisis más profundo de la estructura de similitud y auto-similitud existente en imágenes naturales. Nuestro trabajo parte de una aproximación axiomática reciente a las medidas de si

Abstract:

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior<br>Este trabalho apresenta uma família de novos métodos numéricos euleriano-lagrangeanos localmente conservativos para leis de conservação hiperbólicas escalares. Estes métodos não utilizam soluções analíticas de problemas de Riemann e são bastante precisos na captura de saltos nas soluções. Estes métodos foram introduzidos, implementados computacionalmente e testados para leis de conservação em uma e duas dimensões espaciais. Foram consideradas as equações de Burgers e Buckley-Leverett. Nossos experimentos numéricos indicaram que os
