Abstract:
The type of algorithm employed to classify remote sensing imageries plays a great role in affecting the accuracy. In recent decades, machine learning (ML) has received great attention due to its robustness in remote sensing image classification. In this regard, random forest (RF) and support vector machine (SVM) are two of the most widely used ML algorithms to generate land cover (LC) maps from satellite imageries. Although several comparisons have been conducted between these two algorithms, the findings are contradicting. Moreover, the comparisons were made on local-scale LC map generation e

Abstract:
In this study, fuzzy logic modeling was implemented to fuse the thematic layers derived from principal components analysis (PCA) in order to generate mineral prospectivity maps. Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) and WorldView-3 (WV-3) satellite remote sensing data were used. A spatial subset zone of the Central Iranian Terrane (CIT), Iran was selected in this study. The PCA technique was implemented for the processing of the datasets and for the production of alteration thematic layers. PCA4, PCA5, and PCA8 were selected as the most rational alteration them

Abstract:
Knowledge of brain connectivity is an important aspect of modern neuroscience, to understand how the brain realizes its functions. In this work, neural mass models including four groups of excitatory and inhibitory neurons are used to estimate the connectivity among three cortical regions of interests (ROIs) during a foot-movement task. Real data were obtained via high-resolution scalp EEGs on two populations: healthy volunteers and tetraplegic patients. A 3-shell Boundary Element Model of the head was used to estimate the cortical current density and to derive cortical EEGs in the three ROIs.

Abstract:
Le présent travail a pour but le développement d’une caméra gamma à masque codé permettant d’estimer la position tridimensionnelle (3D) des sources radioactives. Cela est d’un intérêt considérable dans le cadre d’un grand nombre d'applications, de la reconstruction de la forme 3D des objets radioactifs aux systèmes de réalité augmentée appliqués à la radioprotection. Les caméras gamma portables actuelles ne fournissent que la position angulaire relative des sources gamma à localiser, c'est-à-dire qu'aucune information métrique concernant les sources n’est disponible, comme par exemple leur dis

Abstract:
Les travaux décrits dans cette thèse sont centrés sur l'évolution de l'imagerie médicale nucléaire, des techniques d'imagerie fondamentales aux innovations actuelles, avec un focus particulier sur la caméra XEMIS2. Cette caméra Compton au xénon liquide est conçue pour l'imagerie 3-gamma des petits animaux à faible activité. L'objectif principal de XEMIS2 est de localiser en trois dimensions un radiopharmaceutique marqué avec un radionucléide spécifique, tel que le Scandium-44, tout en réduisant l'activité administrée sans compromettre la qualité de l'image.La thèse se concentre ensuite sur le

La caméra Compton XEMIS2 a pour objectif de démontrer expérimentalement l’efficacité d’une chambre à projection temporelle au xénon liquide pour la détection de traceurs émettant trois photons gamma, en vue de produire des images de petits animaux. Cette nouvelle modalité d’imagerie permettrait d’obtenir une qualité d’image comparable à celle des systèmes TEP utilisés en contexte clinique, mais avec une activité injectée 100 fois plus faible. Un nouvel axe d’optimisation de la caméra XEMIS2 consiste à réduire le temps d’acquisition des images, passant de 20 minutes à seulement 2 minutes. En co

Abstract:
Une technique d'imagerie innovante reposant sur la localisation tridimensionnelle d'un radioisotope émetteur (bêta, gamma) à l'aide d'un télescope Compton au xénon liquide a été proposée au laboratoire SUBATECH en 2003. Cette technique, appelée imagerie 3 gammas, repose sur l'association d'une caméra à tomographie d'émission de positons pour la reconstruction des deux photons d'annihilation et d'une chambre à projection temporelle au xénon liquide pour la reconstruction du troisième photon. L'interaction de ce dernier avec le xénon liquide induit un signal de scintillation, lu avec un tube pho

Abstract:
High-cost deepwater, high-pressure/high-temperature (HP/HT), and extended-reach wells in conventional reservoirs drove impressive developments in logging-while-drilling (LWD) technology in recent decades. However, the length, cost, and mechanical specifications of traditional LWD tools make them generally unattractive for use in onshore unconventional reservoirs, which present very different economic and technical challenges. This has led to the development of a compact integrated LWD tool optimized for geosteering, evaluating, and optimally completing unconventional reservoirs. Azimuthal spec

Abstract:
Abstract One of the major challenges in low resistivity pay zones (below 1 ohm.m) is to map the surrounding boundaries and the reservoir thickness. This has a significant impact on the understanding of the subsequent hydrocarbon production. This case study presents an effective approach in two recent wells where effective well placement and formation evaluation were achieved using Multiple Logging While Drilling (LWD) sensors, including Ultra-Deep Azimuthal Resistivity (UDAR) mapping technology in low resistivity carbonate zone.
