Conception en technologie CMOS d'un Système de Vision dédié à l'Imagerie Rapide et aux Traitements d'Images
2008
Our work presented in this thesis focuses on the design, testing and implementation of monolithics CMOS image smart sensors : The principle, performance and limitations. The hardware implementation of a vision smart system is the central link. HISIC is High Speed Image Capture with processing at pixel level. An experimental platform for instrumentation and evaluation of retina operators was conducted during this thesis. After a state of the smart sensors and CMOS retinas, the second part is dedicated to the study and design of the pixel image sensor HISIC. Two circuits were realized in CMOS technology. The first identied a new type of photo-detector, and the second, to create a prototype em…
Decoupled control scheme of grid-connected split-source inverters
2017
Grid-connected power conversion systems for renewable energy sources must fulfill several requirements, e.g., the high efficiency, the reduced cost and complexity, and, quite often, the boost capabilities that is usually achieved using a front-end dc–dc boost converter before the inversion stage, leading to a two-stage architecture. Meanwhile, single-stage power conversion systems, which perform the boosting operation within the inversion one, offer some potential advantages, in terms of reducing the complexity and the volume of the whole system. Among several proposed options, the split-source inverter (SSI) has been recently proposed by Abdelhakim et al. as an alternative option with some…
Excess electronic recoil events in XENON1T
2020
We report results from searches for new physics with low-energy electronic recoil data recorded with the XENON1T detector. With an exposure of 0.65 t-y and an unprecedentedly low background rate of $76\pm2$ events/(t y keV) between 1 and 30 keV, the data enables sensitive searches for solar axions, an enhanced neutrino magnetic moment, and bosonic dark matter. An excess over known backgrounds is observed at low energies and most prominent between 2 and 3 keV. The solar axion model has a 3.4$\sigma$ significance, and a 3D 90% confidence surface is reported for axion couplings to electrons, photons, and nucleons. This surface is inscribed in the cuboid defined by $g_{ae}<3.8 \times 10^{-12}$,…
Zagadnienie inwentarzy w muzeach i inwentaryzacji kolekcji w świetle dorobku normatywnego UNESCO
2022
W artykule przedstawiono zagadnienia inwentarzy w muzeach i inwentaryzacji kolekcji w świetle dorobku normatywnego UNESCO jako podmiotu wyznaczającego standardy zawarte w dokumentach wiążących i o charakterze soft law (zalecenia). Zaprezentowano kwestie związane z implementacją Konwencji UNESCO z 1970 r. dotyczącej środków zmierzających do zakazu i zapobiegania nielegalnemu przywozowi, wywozowi i przenoszeniu własności dóbr kultury, z rekomendacjami UNESCO dotyczącymi muzeów oraz ze znaczeniem ewidencjonowania dóbr kultury w walce z nielegalnym obrotem ruchomymi składnikami dziedzictwa kultury. Wobec nowych wyzwań, w tym ostatnich konfliktów zbrojnych, ewidencjonowanie dóbr kultury jest sz…
Vers un environnement informatisé d'évaluation de la qualité ergonomique d'interfaces multimédia : Étude exploratoire
2000
Our objective is to encourage the human-computer interface designers to be more interested in the uses made of their product by taking into account to a higher degree the human-factor in the testing phase which often is too focused on technical aspects. We want to facilitate the integration of the user as a source of evaluation during the testing phase. Our aim is to offer the designer a software environment of practical tests that allow them to have their own products evaluated by their users. We undertook an experiment to explore the feasibility of this project.

Search for the Decay of the Higgs Boson to Charm Quarks with the ATLAS Experiment
2018
A direct search for the standard model Higgs boson decaying to a pair of charm quarks is presented. Associated production of the Higgs and Z bosons, in the decay mode ZH→ℓ+ℓ−c¯c is studied. A data set with an integrated luminosity of 36.1 fb−1 of pp collisions at √s=13TeV recorded by the ATLAS experiment at the LHC is used. The H→c¯c signature is identified using charm-tagging algorithms. The observed (expected) upper limit on σ(pp→ZH)×B(H→c¯c) is 2.7 (3.9+2.1−1.1) pb at the 95% confidence level for a Higgs boson mass of 125 GeV, while the standard model value is 26 fb.
