Modélisation, Analyse et Traitement de l'Information
2016
Mes activités de recherche s’articulent, d’une part, autour de l’instrumentation et du génie biomédical,et, d’autre part, autour du traitement et de la transmission non linéaire de l’information. Elles sebasent sur la modélisation des signaux à partir de modèles non linéaires (principalement modèles deréaction-diffusion. . . ) continus (EDP) et discrets (numériques). Dans cette partie, d’un point de vuefondamental, des phénomènes dynamiques complexes ou chaotiques sont caractérisés à travers l’analyse,la classification, la reconnaissance des motifs dans des signaux physiologiques ou issus des circuitsélectroniques. Un autre axe sur lequel je travaille concerne l’analyse et le traitement des…

Une mariophanie martiale à Dijon
2015
The ”delivrance de Dijon” in 1513 is an ambiguous event that mixes original procession, memorial procession, votive tapestry and historiographical interpretation. This paper studies, in this ”millefeuille”, the uses of martial miracle of the Virgin Mary in favor of Dijon inhabitants. What is the role of these invocation-purposed processions in the panic context of war and in the Marian piety of the Burgundian renaissance ? The Mariophany of the delivrance must not be interpreted in the light of negotiations between the city and the besiegers and a treaty that saves the city and its inhabitants, but sees Louis XII unhappy ? Finally, doesn’t divine intervention result from the power of the im…

Dark Count rate measurement in Geiger mode and simulation of a photodiode array, with CMOS 0.35 technology and transistor quenching.
2014
International audience; Some decades ago single photon detection used to be the terrain of photomultiplier tube (PMT), thanks to its characteristics of sensitivity and speed. However, PMT has several disadvantages such as low quantum efficiency, overall dimensions, and cost, making them unsuitable for compact design of integrated systems. So, the past decade has seen a dramatic increase in interest in new integrated single-photon detectors called Single-Photon Avalanche Diodes (SPAD) or Geiger-mode APD. SPAD detectors fabricated in a standard CMOS technology feature both single-photon sensitivity, and excellent timing resolution, while guarantying a high integration. SPAD are working in ava…

Etude des propriétés de coordination de nouveaux ligands macrocycliques vis-à-vis de cations métalliques en vue de l'utilisation de leurs complexes p…

Noninvasive medical imaging techniques such as single-photon emission computed tomography (SPECT) or positron emission tomography (PET), are valuable tools for the development and validation of new therapeutic molecules. That approach requires the conjugation of a radioactive source emitting either y-rays or positrons with a biological tracer (e.g. DOTATOC). Among the potentially useful radionuclides available, 111In3+ (SPECT), 64Cu2+, and 68Ga3+ (PET) have attracted increasing attention over the last years for medical applications. To minimize the in vivo release of the radioactive cation by transmetalation or transchelation with biological ligands, it is essential to trap selectively the …
Fluorescent organometallic complexes : when the photovoltaic leads to theranostics
2013
The goal of my PhD thesis was to synthesize new molecules, which give access to fluorescentorganometallic complexes with interesting properties for photovoltaic and theranostic. In thisproject, several main points have been studied.The first part of this manuscript concerns the synthesis of new metallocene and metalloporphyrinsbasedorganometallic complexes to the design of solar cells. After a short introduction, wepresented the synthesis of titanium complexes and metalloporphyrins in the first chapter. Inparticular, we described the synthesis of model compounds and the difficulties encountered duringthe transition to porphyrin derivatives. However, in view of results obtained and opportuni…
A Neural Network Meta-Model and its Application for Manufacturing
2015
International audience; Manufacturing generates a vast amount of data both from operations and simulation. Extracting appropriate information from this data can provide insights to increase a manufacturer's competitive advantage through improved sustainability, productivity, and flexibility of their operations. Manufacturers, as well as other industries, have successfully applied a promising statistical learning technique, called neural networks (NNs), to extract meaningful information from large data sets, so called big data. However, the application of NN to manufacturing problems remains limited because it involves the specialized skills of a data scientist. This paper introduces an appr…
