Statistical analysis of the relation between metallic microstructures and mechanical properties
2020
This thesis aims at the development of physical relations between the intricate 3D features of metallic microstructures and the mechanical properties of the material. For understanding which are the microstructural determinants of the resultingmechanical behaviour of metals, a deep quantitative characterisation of the microstructure is needed. The main steps of quantitative characterisation of the microstructures are: identification of the phases distribution and their chemical composition, study of the microstructure morphology (geometrical arrangement of grains, grain boundaries, grain orientations, grain size and grain shape). An accurate description of the microstructure features enrich…
Modelling urban stormwater impact mitigation by using bmps and storage tanks
2005
The continuous growth of urban areas and the increasing public awareness about environmental impact of stormwater raised high interest on quality impact on the receiving water bodies. Indeed, in the last decades, large efforts have been provided for improving urban drainage systems in order to mitigate environmental impacts. In the present paper, a simplified modelling approach has been developed in order to evaluate the mitigation efficiency of different BMP schemes including infiltration and storage facilities and both considering possible distributed controls and centralised structures. The main goals of the research are the simulation of BMP efficiency in different operational condition…

Intelligence stratégique et dissimulation dans les outils de géovisualisation en ligne
2014
Interactive geovisualization portals, set up on the Internet after the iconic Google Maps, are highly regarded by the public. They provide the ability to see from above the surface of our planet, and more specifically the French territory in the case of Geoportail. Yet it is forbidden to approach too close to certain objects: on national territory, some 150 sites are in fact hidden by the IGN. This paper question the relevance and efficiency of this operation imposed on the main body of production and dissemination of spatial information in France, in comparison with the means used by other countries.
Towards a Guidance System to Aid in the Dosimetry Calculation of Intraoperative Electron Radiation Therapy
2015
In Intraoperative Electron Radiation Therapy (IOERT), the lack of specific planning tools limits its applicability, the need for accurate dosimetry estimation and application during the therapy being the most critical. Recently, some works have been presented that try to overcome some of the limitations for establishing planning tools, though still an accurate guidance system that tracks, in real-time, the applicator and the patient is needed. In these surgical environments, the acquisition of an accurate 3D shape of the patient’s tumor bed in real-time is of high interest, as current systems make use of a 3D model acquired before the treatment. In this paper, an optical-based system is pre…

Joint Subcarrier and Phase Shifts Optimization for RIS-aided Localization-Communication System
2022
Joint localization and communication systems have drawn significant attention due to their high resource utilization. In this paper, we consider a reconfigurable intelligent surface (RIS)-aided simultaneously localization and communication system. We first determine the sum squared position error bound (SPEB) as the localization accuracy metric for the presented localization-communication system. Then, a joint RIS discrete phase shifts design and subcarrier assignment problem is formulated to minimize the SPEB while guaranteeing each user’s achievable data rate requirement. For the presented non-convex mixed-integer problem, we propose an iterative algorithm to obtain a suboptimal solution …
