X-ray tomographic method for measuring three-dimensional deformation and water content distribution in swelling clays
2015
A non-invasive method for simultaneous measurement of the 3D displacement field and the water content distribution of a wetted solid material is developed. The method is based on comparison of X-ray tomographic images of a material sample in the reference state and in the wetted and deformed state. The deformation and water content analyses were successfully compared with numerical results for a cylindrical rubber test sample under axial compression, and with gravimetric results from axially wetted and sliced cylindrical bentonite samples, respectively. The methods were applied in a 4D study (three spatial dimensions and time) of wetting and deformation of purified swelling bentonite doped …

Spilling the beans: The development of conceptual knowledge about food and its links with food rejection in young children (3-7-years-old)
2021
Insufficient dietary variety in children leads to significant nutrient deficiencies and health issues, both in childhood and later life (DeCosta et al., 2017). Cognitive mechanisms, such as categorization and conceptual knowledge, play an important role in understanding and appropriately accepting or rejecting foods (Mura Paroche et al., 2017). The food domain lends itself to many concepts and categories, such as taxonomic (i.e., lamb is meat), thematic (i.e., lamb goes on a plate), or script (i.e., lamb is eaten at dinner). Such knowledge aids accurate recognition, understanding, and appropriate interaction when confronted with foods situated in context. If conceptual knowledge is underdev…
Évaluation d'un Programme de Réussite Éducative
2010
Rapport, commandité par le Grand Dijon; Ce rapport rend compte de l'évaluation des projets de réussite éducative de l'agglomération dijonnaise. La première partie vise à cerner les enjeux de la réussite éducative et présente les grandes lignes de la démarche d'évaluation. La seconde partie s'attache à décrire le contexte d'intervention du projet sur les territoires en termes de public et d'actions. La troisième partie traite de l'efficacité du projet dans ses différentes dimensions. En conclusion, les pistes de réflexion les plus pertinentes sont dégagées sur la base de l'ensemble des analyses produites lors de cette évaluation.

Vjetnamiešu kopiena Latvijā: akulturācijas modeļa analīze
2021
Bakalaura darba “Vjetnamiešu kopiena Latvijā: akulturācijas modeļa analīze” mērķis ir noskaidrot Latvijā esošās vjetnamiešu kopienas plānus, uzskatus un mērķus saistībā ar akulturāciju, un lai varētu izprast šīs kopienas vēlamo akulturācijas stratēģiju un piedāvāt ieteikumus priekš valsts politikas. Darbs tika izstrādāts balstoties uz zinātniskās literatūras pētniecību un autora pašizveidotās aptaujas, rezultātu apkopojumu un analīzi. Bakalaura darbu veido 3 daļas, kur tiek apskatīts akulturācijas vēsturi un stratēģijas, kā arī vjetnamiešu kopienu vēsturi citās valstīs, aptaujas izveidi un datu apkopošanu, rezultējoties ar datu analīzi un priekšlikumu izteikšanu. Neieskaitot titullapu, satu…
Search for scalar leptoquarks in pp collisions at $\sqrt{s}$=13 TeV with the ATLAS experiment
2016
An inclusive search for a new-physics signature of lepton-jet resonances has been performed by the ATLAS experiment. Scalar leptoquarks, pair-produced in pp collisions at s √s = 13 TeV at the large hadron collider, have been considered. An integrated luminosity of 3.2 fb-1, corresponding to the full 2015 dataset was used. First (second) generation leptoquarks were sought in events with two electrons (muons) and two or more jets. The observed event yield in each channel is consistent with Standard Model background expectations. The observed (expected) lower limits on the leptoquark mass at 95% confidence level are 1100 and 1050 GeV (1160 and 1040 GeV) for first and second generation leptoqua…
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.
Beam-induced and cosmic-ray backgrounds observed in the ATLAS detector during the LHC 2012 proton-proton running period
2016
This paper discusses various observations on beam-induced and cosmic-ray backgrounds in the ATLAS detector during the LHC 2012 proton-proton run. Building on published results based on 2011 data, the correlations between background and residual pressure of the beam vacuum are revisited. Ghost charge evolution over 2012 and its role for backgrounds are evaluated. New methods to monitor ghost charge with beam-gas rates are presented and observations of LHC abort gap population by ghost charge are discussed in detail. Fake jets from colliding bunches and from ghost charge are analysed with improved methods, showing that ghost charge in individual radio-frequency buckets of the LHC can be resol…
