"From outcrop to fluid-flow : sedimentary architecture, permeability heterogeneity, and effect of sedimentary facies in fluid-flow modelling : a case study of the middle buntstandstein continental sandstones (lower triassic, eastern France)". Electronic Thesis or Diss., Strasbourg, 2024. http://www.theses.fr/2024STRAH006.
Texto completo da fonteAt the Upper Rhine Graben, in Eastern France, the Lower Triassic Buntsandstein serves as an important reservoir of groundwater and lithium-rich geothermal brines. The scientific objective of this study is to comprehend the architecture of the Lower Grès Vosgien Formation (LGV), Middle Buntsandstein; how sedimentological processes, at different scales, generate significant permeability heterogeneities; and the effect of such heterogeneity in fluid-flow modelling results. The study employs high-resolution sedimentological characterisation, through vertical profile descriptions, digital outcrop model, and petrographic analysis. Subsequently, permeability measurements are coupled with sedimentological data, to identify different scales of sedimentary controls on permeability distribution. Finally, a realistic 2D hydrostratigraphyc conceptual model is generated as a reference, to evaluate how different scenarios of heterogeneity simplification impact fluid-flow modelling, concerning particle residence time, macro-dispersivity and upscaled anisotropy.Results indicate that 93% of the LGV is composed of sandstones deposited by a braided fluvial system, with evidence suggesting that discharge variability was a main depositional controlling factor of sedimentary facies and heterogeneity distribution. The LGV stacking pattern reveals periods when fluvial processes were absent, and aeolian processes dominated sediment transport and deposition, constituting 7% of the total LGV thickness. The aeolian deposits record indications of persistent water in the system, either due to water table rise or ephemeral floods In the fluvial channel facies association, an inverse relationship between fluvial flow regime conditions and the permeability of its facies is observed. In the wind- and water-laid facies association (WWL), permeability distribution is directly influenced by climatic conditions, where low permeability hybrid sand sheets were deposited in more humid conditions, and high permeability aeolian dunes in more arid conditions. However, despite the high permeability of the AD, the architecture of the WWL implies low connectivity potential. Compaction is the main process influencing the permeability and porosity of the LGV. Samples with a higher proportion of lithoclasts and infiltrated clay recorded a more advanced degree of compaction, whereas samples with a higher percentage of quartz overgrowth exhibited a lower degree of compaction. The diagenetic overprint affected the distinct facies differently, indicating that primary sedimentary processes and architecture govern the distribution of permeability heterogeneity in the LGV. Permeability data from outcrops exhibited median values up to three orders of magnitude higher than those from subsurface data. However, the same facies, and similar trends of relative porosity-permeability responses to the distinct facies, are observed between outcrops and borehole samples, highlighting sedimentology as an indispensable proxy for reservoir heterogeneity studies[...]

Texto completo da fonteL'analyse de la problématique de traitement des hologrammes numériques sous des angles de traitement du signal et de déconvolution nous permettent de présenter les apports variés de la littérature sous un cadre unifié. Nous suggérons d'utiliser une formulation de type ``problème inverse'' basée sur le modèle physique de formation de l'hologramme pour résoudre les difficultés posées par les artefacts des images restituées. L'algorithme proposé permet de réaliser la détection de micro-particules dans un volume d'étude 4 fois supérieur et avec une précision améliorée d'un facteur 5 par rapport à la technique classique.
L'enjeu du traitement rapide d'hologrammes nous a poussés à développer une approche de stéréologie en projection donnant accès à une estimation de la taille moyenne ou de la distribution d'orientations d'une population de micro-objets.

Texto completo da fonteA hologram of micro-objects contains information about the size, shape and 3D localization of the objects. This information is coded in the hologram by the frequency and amplitude modulations of the interference fringes. The extraction of this information is classically done by analyzing the 3D volume reconstructed with a Fresnel transform, a fractional Fourier transform or a wavelet transform. However, several types of artifacts appear in the reconstructed images : distorsions close to the image boundaries, multiple focusing, twin-images. The analysis of the issue of digital hologram processing under the light of signal processing and deconvolution makes it possible to give a unified description of previous contributions found in literature. We suggest an “inverse problem” approach based on the physical model of hologram formation to circumvent the artifacts of reconstructed images. The proposed algorithm detects micro-particles in a volume 4 times larger and with a precision improved by a factor 5 compared with classical techniques. On-line processing of digital holograms requires fast processing algorithms. We have developed a stereological approach to estimate the mean size or the distribution of directions of a population of micro-objects

Texto completo da fonteThis work presents various original methods of flows analysis based on a colour tomographic illumination. The first technique developed is the polychromatic sequential tomography based on the use of an acousto-optic tunable filter. This method is used to perform visualizations (pulsed lighting and colour coding) and to determine velocities in two-dimensional recirculating flows. The second technique carried out is the polychromatic laser tomography (three parallel volumes of light). It is applied in hydrodynamics in order to visualize two-dimensional and three-dimensional flows. The extension of this method to all the wavelengths of visible (resulting from the dispersion of the white light) makes it possible to develop a new technique of three-dimensional visualization and a "Rainbow Volumic Velocimetry". These three methods of investigation are applied successfully to different 2D or 3D flow configurations (eddy, recirculations, wakes, jets. . . )

Texto completo da fonteSouthwest Asia and in particular the Iranian plateau, at the crossroads of Africa, Europe and Asia, constitute a rather unique area with a long and diversified history. In Middle Paleolithic, the whole region has often been considered as a place for passage of anatomically different humans: Homo Sapiens and Neanderthal. However, for several reasons, researchers focused their activities, on the region of Levant and Zagros, therefore the southern parts and the east of Caspian Sea are much less studied. As Mousterian of the near east region is marked by the predominance of Levalloisdebitages, in Torus region (regions in the west of Caspian Sea including current Azerbaijan and Georgia), the lithic industries are characterized by so-called Micoquian bifacial pieces. In this context, a very important question is what happened in the east and the south of Caspian Sea,between these two great areas of influence.A deep study of lithic tools has been conducted on five assemblages of Iran andTurkmenistan, by a technological and techno-functional approach. The obtained results show that if in the east of Caspian Sea the bifacial tradition is well attested in some Turkmen industries, it attests various technical systems. These elements lead us to make the link with the other "techno-complexes" so far less known. It would seem, therefore, that Turkmenistan and eastern Iran represent a crossroads where different techno-complexes could meet.This diversity of technical systems seems to indicate a complexity more than expected of dynamics of populations during Mousterian. Thanks to the demonstration of the technical variation, we will try to perceive and reconstruct these phenomena of populations, the mobility of prehistoric human groups, in the environment that they occupied
جنوب غرب آسیا و به خصوص فلات ایران، در تقاطع قاره های آفریقا، اروپا و آسیا، منطقه ای نسبتا منحصر به فرد با تاریخی طولانی و متنوع را تشکیل می دهند. در طول دوره پارینه سنگی میانی، این منطقه اغلب به عنوان مکانی برای عبور گونه های مختلف انسان: انسان هوشمند باستانی و نئاندرتال در نظر گرفته شده است. با این حال، به دلایل مختلف، محققان اغلب در انجام فعالیت های علمی خود در منطقه لوانت و زاگرس متمرکز بوده اند بخش های شرقی دریای خزر بسیار کمتر مورد مطالعه قرار گرفته اند.اگر موسترین در منطقه خاورمیانه با تراشه برداری لوالوا عجین شده است، منطقه توروس در غرب دریای خزر (شامل آذربایجان و گرجستان کنونی) با قطعات دو طرفه از نوع میکوکین شناخته می شود. در این زمینه، سوال مهم مطرح این است که چه اتفاقی در شرق و جنوب دریای خزر، بین این دو حوزه بزرگ رخ داده است؟در این راستا، مطالعه ایی بسیار گسترده توسط روش های تجزیه و تحلیلی فن آوری و فنی-کاربردی بر روی ابزارهایی از پنج مجموعه از ایران و ترکمنستان انجام شد. نتایج به دست آمده نشان می دهد که علی رغم حضور ابزارهای دو طرفه در برخی از صنایع ترکمنستان، در شرق دریای خزر شاهد سیستم های تکنیکی متفاوتی هستیم. این عناصر ما را بر آن می دارد که به دنبال ارتباط آنها با سیستم های فنی ای باشیم که تا کنون کمتر شناخته شده اند. به نظر می رسد که ترکمنستان و مناطق شرقی ایران، محل تقاطع سیستم های فنی مختلفی باشند.این تنوع در سیستم های فنی احتمالا از آنچه پیشتر در مورد پویایی جمعیت در طول دوره موسترین تصور می شد بسیار پیچیده تر باشد. به لطف شناسایی این گوناگونی های فنی است که ما سعی می کنیم پدیده های مربوط به جمعیت و جابجایی گروه های انسانی پیش از تاریخ در محیط مورد اشغال آنها را درک و بازسازی کنیم

Texto completo da fonteThis work is a quantitative investigation of intra-cortical micro-vascular networks using a new micro-tomography imaging protocol which permits a complete scan of the entire gray matter with a micron resolution. The first part of the PhD is devoted to the analysis of very large 3D images coming from healthy rats and marmosets primate cortex, as well as tumour implanted rats brains. Classical methods are used for binarisation and squeletonization of the images. The influence of the experimental protocol on the obtained images is evaluated. A fast and original method is proposed to fill the gaps of incompletely injected vessels the efficiency of which is tested and validated. The second part of the PhD is concerned by the statistical analysis of geometrical, local and topological properties of micro-vascular networks. Geometrical properties are related to the spatial distribution of vessels from studying the vascular density and the vessel/tissue distance map. We brought to the fore the multi-scale properties of those fields from fractal and spectral analysis up to a some cut-off which defines the typical length-scale of an elementary representative volume. We found that this length-scale significantly differ in normal and tumoral tissues. The local analysis of vessel's segment length systematically exhibits exponential distribution, which leads to some characteristic segments length. Those length significantly differ in adult and new-born primates tissues. This analysis is consistent with the result obtained on the vascular density and leads to the conclusion that developmental angiogenesis occurs mainly at the capillary scale. .

Texto completo da fonteThe various aspect of cardiac function may now be investigated non-invasively by cardiac imaging. Cardiac magnetic resonance (CMR) allows to study multiple parameters in one time, including function, perfusion, tissular characteristics and fibrosis. There is a need to propose adequate and objective criteria for CMR analysis, which may be warranted by a quantitative analysis. We prospectively followed 195 patients with a first ST elevation myocardial infarction and successful revascularisation. CMR were performed at baseline and 3 months. We analysed ventricular volumes, systolic wall stress, infarct size, microvascular obstruction, and pericardial effusion extent. A cohort of 42 patients with hypertrophic cardiomyopathy were also studied. We demonstrated the clinical interest for semi-automated analysis of late gadolinium enhancement imaging. The use of the FWHM algorithm appeared strongly related to left ventricular volumes at 3 months. Then we depicted the lack of relationships between electrocardiograms and fibrosis in patients with hypertrophic cardiomyopathy. The presence of q waves appeared to be related to cardiac phenotype, namely higher septal to posterior ratios. We showed the impairment of myocardial deformations in regard of myocardial fibrosis following a myocardial infarction. We found a much depressed deformation in case of microvascular obstruction and an interest for longitudinal global strain for the prediction of infarct size at 3 months. We also studied the determinants of post-infarction heart failure on one part, pericardial effusion on the other, by the use of a CMR multiparametric approach. Infarct size and systolic wall stress were the best markers of in-hospital and post-discharge heart failure, respectively. A pericardial effusion was found in 58.5% of the patients with a mean size of 31.6±24.0 ml. The determinants by multivariate analysis were infarct size, microvascular obstruction and systolic wall stress. Our results highlighted the interest for a quantitative and multiparametric approach of CMR. Further applications are expected in both descriptive and randomized studies

Texto completo da fonteThe mousterian of quina facies has been defined as an industry singularised by its debitage, its typological components and the retouches of its implements. The present study purposes to identify the types of retouches met in four lithic industries of the vallee du rhone (le figuier, neron, ardeche - la carriere chaumette, le champ-grand, loire). Within mousterian industries, the presence of typically retouch seemed to be one of the most significant characters of quina's facies. The initial hypothesis was to attempt a strict definition of retouch'types, particulary for quina's retouch, to carry out comparisons between the morphometrical characters of the implements. Therefore, we choose to use a quantitative method. Each tool was identified by several criterias, qualitative and quantitative, in reference to either retouches characters or artefact's characters. The retouches and pieces areas have been measured by image analysing which offers exact sizes (counting the three dimensions of the piece). Using multivariate analysis, it was possible to validate the hypothesis. The quantitaive features of the retouch were proved satisfactorily discriminant, in order to asses homogeneous and definited technical choices for each type of retouches. Furthermore, the four lithic industries shared the same choices. The lithic production seemed to comply with the technical imperatives induced by the production of retouches. Therefore some of them needed particular support. The results yielded, allowed in favour of mastering of the retouches process that is as elaborated as the debitage process. Analogies between toolkits characters and retouches types of the four lithic industries abound towards a community of cultures

Texto completo da fonteIn this work it was developed a methodology for qualifying and quantifying rubber compounds destined for facings manufacture. These compounds are formed by a large number of components which use, beyond the elastomeric base, a resin that is used as a process agent, vulcanization agents and different fillers, each one with a specific function. The elastomeric systems are characterized by properties that could be affected by the addition or removal of some ingredient and also by variations in its concentration. The rubber compounds are produced by an outsourced company, so the development of a variety of analytical tools for monitoring these systems is essential, since these compounds are the basis of a facing formulation. For developing this methodology, TG/DTG, FTIR, GC and EDXRF were used as techniques. The first step was an exploratory and a pre-formulation study for a qualitative characterization of each raw material in rubber compound. In the second stage, several samples with known concentrations of the quantifying component were prepared. The quantification of graphite and carbon black was made directly by means of TG/DTG technique. For quantifying the other components, analytical curves of response (FTIR, GC and EDXRF) vs. variation of concentration were elaborated. A strong/perfect and positive correlation between the variables was observed and the equations presented good fit with the linear regression model. By means of the analytical curves it was possible to determine the amounts of unknown concentration rubber compounds.

Texto completo da fonteCar manufacturers are facing many constraints, both economic and ecological. Therefore, the development of automobile engines must satisfy a will to reduce fuel consumption and emission of pollutants. This reduction requires a very fine atomization control, which is the first step in any process of liquid combustion. Indeed, understanding of fuel injection parameters is an essential link to the optimization of the combustion process. This work, applied to the high-pressure Diesel injection, offers analysis methods able to characterize the atomization behavior by introducing relevant quantitative variables. The principle of this approach is to examine a set of images, resolved in space and time to determine the characteristics of the jet near injection outlet. The extreme conditions of the diesel injection justifies the need to use sophisticated optical techniques, ultra-fast shadowgraphy coupled with a double pulse femtosecond laser source. Main features extracted are: the morphology of the jet at different spatial scales, the efficiency of atomization, the deformation of the liquid/gas interface and the liquid velocity structures. These quantities are then used as tools of comparison between simulations and experiments

Texto completo da fonteSimultaneous measurement of kinematic and thermal full fields are very important for thermomechanical procedures. Silicon-based cameras are widely used to perform real-time observation of the kinematic fields, mainly thanks to digital image correlation. Moreover, they are known to be as well sensitive in the near-infrared spectral range, thus the acquirement of thermal fields using silicon-based cameras is possible. However, there are two main problems for the silicon-based camera to obtain simultaneously kinematic and thermal fields. One is that in the near-infrared spectral range, a small temperature variation will lead to a large modification in the image gray level, which easily leads to poor quality images. Another is that digital image correlation needs a heterogeneous and contrasting surface, while the near-infrared thermography needs a homogeneous and constant surface. In this thesis, an innovative technique was proposed to automatically adjust the exposure time of the camera to obtain kinematically and thermally exploitable images whatever the temperature evolution occurs on the surface of the observed object. This technique was validated by different experiments, including blackbody heating experiments and realistic specimen heating experiments. Radiometric models of blackbody and specimen surfaces ware calibrated respectively. Based on the radiometric models, thermal fields have been reconstructed on the kinematically and thermally exploitable images. High temperature tube ballooning experiment is conducted to perform both kinematic and thermal fields. Global digital image correlation was performed to obtain kinematic fields. To perform near-infrared thermography on the specimen surface, radiometric model is calibrated based on portions of the brightest pixels. In this case 20% of the brightest pixels are used to perform radiometric model calibration. Based on the radiometric model using 20% of the brightest pixels, the thermal fields are reconstructed. Combined with the known coordinates of kinematic fields by digital image correlation, the thermal fields at the same coordinates as kinematic fields can be obtained
