Full textOne of the key elements for achieving a high efficiency in solar power plants with volumetric receiver is the absorber. Its porous structure allows the solar radiation to penetrate inside it, where the absorbed energy should be transferred efficiently by convection to the fluid which crosses through it. In this work, two types of innovative absorbers are presented and analyzed: one consisting of a set of stacked elements with a grid-like structure, the other with elements similar to venetian blinds. As a reference, a conventional honeycomb absorber is also evaluated. The solar radiation propagation within the absorbers is modeled through the ray tracing technique, based on the Monte Carlo method. Their thermohydraulic behavior is simulated by the finite element method. The geometrical characteristics of the two proposed absorbers improve convective heat transfer compared to honeycomb absorbers and the modification of their main geometric parameters allowed us to increase the extinction length of solar radiation. However, the increase of their apparent frontal surface rises up reflection losses. Based on the theoretical results, the venetian blind absorber was selected to analyze it experimentally. Its thermal performance is compared with that of a honeycomb absorber. These results also indicate that the structure of the proposed absorber intensifies the heat exchange to the fluid. Moreover, this kind of absorber reaches a better thermal behavior at high heat flux and at high flow rates

Full textThis thesis puts forward a novel approach who will make cohabit together the use of a modern technology in a conventional archaeological study focused on Greek architecture. The use of 3D modeling in this doctoral project leads undoubtedly to explore new issues in the Greek archeology. To do this, we will consider to the benefits of this technology to archaeological sciences. Indeed, the restitution of an ancient building in 3D, involves questions on the virtual reality that created. 3D modeling is based on the archaeological material altered by the time. That is why, it is necessary to take a step back on a 3D picture that can idealize an archaeological reality. Our study will also apply to provide solutions to overcome these complications of the virtual restitution. Moreover, the 3D rendition of an ancient building is not an end in itself. In other words, this technology must provide a intuitive approach and a new way to understand the issues that affect at the construction of ancient buildings. Starting with the construction methods or architectural feasibility ... etc.. At the same time, we will conduct an architectural and archaeological examination in order to propose a study that is balanced and that can be reused by archaeological research. Our goals are many and this study wants to be ambitious. For this, this study will strive to avoid the pitfall of proposing an approach that is too restrictive. That is why we plan to combine preferably a study several groups of buildings with different functions. Therefore, taking into account a maximum of archaeological situations our study will be more representative, as this will ensure it a greater likelihood of being reused in the archeological studies. This thesis is also an opportunity to discuss issues related to the promotion of cultural heritage. This topic will also be addressed because the sharing of knowledge should not be accessible only to insiders, but it must also be affordable for the general public. This is an essential task that archeology must carry

Full textThis thesis studies two aspects of a vehicle access control system which relies on the estimation of a key's location to grant access.Firstly, within the context of a triangulation-based system, we study the optimisation of the switching sequence for switched antenna-arrays.A model is given to study the estimation of the parameters of sines received by a switched array, where sensors are not necessarily sampled synchronously.This model is relevant, but not exclusive, to industrial approaches to direction of arrival estimation, such as the one proposed by Bluetooth 5.1, which serves as our reference application.From the model, Cramér-Rao lower bounds are computed, and are used to define design criteria for switching sequences that do not rely on the array's geometry.These criteria's analytical forms allow us to highlight desirable properties in switching sequences, especially in the case where the signal's frequency is unknown.Strategies to build switching sequences are proposed, and numerically evaluated using the provided criteria. Comparison of the criteria with numerical bounds on direction of arrival for common array geometries shows that they are qualitatively linked.Secondly, within the context of a time of flight based system, we propose a system for passenger detection that relies solely on the localization system's original hardware.To achieve this, we propose to use support vector machines (SVM) to classify the channel impulse responses measured between the system's transmitters.A proof of concept is designed to demonstrate feasability, and data is collected on a prototype for further evaluation.By studying the available data, invariants are identified, and processing functions are proposed to translate these invariants to the SVM in order to improve performance.One of the proposed processing is shown to give performance gains for our application through experiments

Full textVarious pollutant contents (ie carbon dioxide, hydrogen sulphide or other sulphur products) are found in produced oils. These latter must undergo a number of transformations and purifications. The design and dimensioning of the corresponding units can well be optimized only if one has reliable and accurate data about phase equilibria and volumetric properties and of course reliable and accurate modeling. This work was devoted partly to measurements of volumetric properties on three binary mixtures (ethane - hydrogen sulphide, ethane - propane and carbon dioxide - hydrogen sulphide). These measurements were carried out using equipment, comprising a vibrating tube densimeter (Paar, model DMA 512 P), which was especially designed and built for this work. The study undertaken about the modeling of volumetric properties made it possible to highlight the inadequacy of the traditional use of cubic equations of state to represent simultaneously volumetric properties and phase equilibria. Among the equations of state investigated, a close attention however was paid to cubic equations of state because of their very great use in the oil field. A new tool was found to adapt cubic equations of state to the simultaneous and satisfactory representation of volumetric properties and phase equilibria. It concerns the coupling of the cubic Redlich-Kwong-Soave equation of state with volume correction through a neural network

Full textAnalysing the progression of brain morphological changes in time series of images is an important topic in neuroimaging. Although the development of longitudinal databases has helped reducing the inter-individual variability, there still exist numerous biases that need to be avoided when capturing longitudinal evolutions. Moreover, when the intra-subject changes are very small with respect to the inter-subject variability it is crucial to know if the available methods can capture the longitudinal change with no bias. In most of the studies, these longitudinal changes are limited to scalar volumetric changes in order to ease their analysis. However, one can observe that brain changes are not limited to volumetry. In this multivariate case, the interpretation is more difficult. This thesis addresses these problems along three main axes. First, we propose a longitudinal Deformation-based Morphometry processing pipeline to robustly estimate the longitudinal changes. We detail the whole sequencing of the processing steps as they are key to avoid adding bias. In addition to this contribution we integrate a modification to the non-linear registration algorithm by masking the similarity term while keeping the symmetry of the formulation. This change increases the robustness of the results with respect to intensity artifacts located in the brain boundaries and leads to increased sensitivity of the statistical study on the longitudinal deformations. The proposed processing pipeline is based on freely available software and tools so that it is fully reproducible
