Pełny tekst źródłaThe application of machine learning techniques based on neural networks provides novel insights into the modelling of the mechanical behaviour of materials. These networks are capable of capturing a wide variety of complex behaviours due to their ability to act as universal function approximators. However, the deployment of these techniques requires large datasets, which are often difficult to obtain experimentally. This manuscript introduces various physical biases that enable the modelling of mechanical behaviour, specifically non-linear viscoelastic behaviour, using limited experimental data, thereby addressing this limitation.The two fundamental principles of thermodynamics provide a robust framework for constraining the formulation of constitutive laws. This approach reduces the quantity of data required for model training, while simultaneously improving the models' resilience to measurement errors.Recurrent neural networks, on the other hand, are particularly well-suited for modelling behaviour that depends on the loading history. Their hidden memories mirror the internal variables introduced in mechanics by the local state principle. However, these networks present challenges in terms of training and generalisation. To overcome these difficulties, a neural network model with mechanical encoding is proposed. This model employs the internal variables of a linear viscoelasticity model to encode the material's history, which proves to be sufficient for modelling its non-linear mechanical behaviour.One of the most significant challenges in three-dimensional modelling from experimental data is the incorporation of material symmetries in order to avoid the need for superfluous testing. For isotropic materials, a method of increasing the data set by randomly rotating the tests, combined with lateral transfer learning, enables the development of a three-dimensional constitutive law using only two types of uniaxial test. A thermodynamically consistent formulation that inherently preserves the material's isotropy is proposed; however, challenges related to training remain to be addressed in order to optimise this approach

Pełny tekst źródłaThe galaxy distribution is biased with respect to the underlying mass distribution. Cosmological bias is larger at high redshift. The understanding of its physical origin can give useful insights about galaxy formation. We use numerical simulations to reproduce the hierarchical structuration of the matter, the accretion and cooling of baryons into dark matter potential wells. These simulations follow explicitly the dynamical evolution of the dark matter and of the baryonic matter in an expanding Universe. They include a set of dissipative processes and follow the chemical evolution of the cosmological plasma. Galaxy formation is computed from recipes describing gas in collapsing regions. We show that galaxy-like objects are in good agreement with the observational data. Clustering differences between galaxies and mass are characterized statistically by bias parameters. However this description is inadequate to understand the complex process of galaxy formation. We take advantage of a probabilistic formalism to separate the non-linearity and stochasticity characteristics of the bias relation between the density fluctuation fields of galaxies and mass. This relation depends on the thermodynamics of baryons justifying the introduction in the simulation of the non-equipartition processes between electrons, neutrals and ions of the cosmological plasma. We discuss in detail about the influence of these processes on the spatial distribution and on the thermodynamical properties of the baryonic matter in not too dense structures at redshifts before the reionization epoch. We point out that low-mass galaxy formation is inhibited at high redshift. It turns out that the cosmological bias relation is modified, underlying the role playing by thermodynamics in the process of galaxy formation

Pełny tekst źródłaRandom search processes can model nuclear reactions or animal foraging. In this thesis, we identify optimal search strategies which minimize the mean first passage time (MFPT) to a target for various processes. First, for symmetric and biased Brownian particles, we compute the distribution of exit times through an opening within the boundary of angular sectors, annuli and rectangles. We conclude on the optimizability of the MFPT in terms of geometric parameters. Second, for walks that switch between volume and surface diffusions, we determine the mean exit time through an opening inside the bounding surface. Under analytical criteria, an optimal desorption rate minimizes the MFPT. We justify that this optimality is a general property through a study of the roles of the geometry, of the adsorption properties and of a bias in the bulk random walk. Third, for active walks composed of straight runs interrupted by reorientations in a random direction, we obtain the expression of the optimal reorientation rate which minimizes the MFPT to a centered spherical target within a spherical confinement, in two and three dimensions. In a last chapter, we model the motion of eukaryotic cells by active Brownian walks. We explain an experimental observation: the persistence time is exponentially coupled with the speed of the cell. We also obtain a phase diagram for each type of trajectories. This model is a first step to quantify the search efficiency of immune cells in terms of a minimal number of biological parameters

Pełny tekst źródłaOur aim is to study the interaction of antiferromagnetic and ferromagnetic materials with well-defined interface by combining structural, electronic and magnetic techniques using synchrotron light. Our interest is guided by the exchange bias effect in thin ferromagnetic films with perpendicular magnetic anisotropy. The main systems studied in this work were ultra-thin layers of chemically-ordered alloys of FePt and MnPt on Pt(001) and of Fe/Ag(001), eventually coupled to CoO. Our strategy was to find an appropriate surface and, for each coupled bilayer, study the individual growth of each element, alloy or oxide. By controlling a variety of parameters, such as surface structure, cleanliness, deposition rate and temperature, we have got a good understanding of the growth process. The coupled systems obtained were studied in situ by grazing incidence X-ray diffraction and ex situ by magneto-optic Kerr effect, X-ray magnetic circular dichroism and X-ray absorption spectroscopy. The relation between the exchange coupling, which manifests itself by an increase in coercivity and a bias field, and the structural characteristics was discussed for the MnPt/FePt and CoO/Fe interfaces.Keywords: exchange bias, chemically ordered alloy, MnPt, FePt, Fe/Ag(001), surface X-ray diffraction, X-ray absorption, MOKE, synchrotron

Pełny tekst źródłaThe main subject of this thesis is the search for an additional heavy Higgs boson through its decay into a pair of Z bosons (H → ZZ(*)) using data recorded with the ATLAS experiment installed at the Large Hadron Collider (LHC). Four distinct analyses are presented, which are distinguished by the decay mode of the Z boson into either a pair of charged leptons (electrons or muons), into a pair of neutrinos or into a pair of quarks, denoted according to final-state, i.e. as 4l, 2l2ν, 2l2q and 2ν2q. The study is performed using 20.3 fb⁻¹ of proton-proton collision data recorded during the first phase of LHC operation (Run-1) at centre-of-mass energy of √s = 8 TeV. A search strategy is employed which segments the data according to the Higgs boson production mechanism, assuming that these are the same as in the Standard Model (SM). Furthermore, the signal is modelled with a width that is small compared to the experimental mass resolution. The Higgs boson mass range considered extends up to 1 TeV for all four decay modes and down to as low as 140 GeV, depending on the decay mode. No significant excess of events over the Standard Model prediction is found. A simultaneous fit to the four decay modes yields upper limits on the heavy Higgs boson production cross-section times H → ZZ branching ratio ranging from 359 fb at mH = 200 GeV to 11 fb at mH = 1 TeV for the gluon-fusion production mechanism, and from 214 fb at mH = 200 GeV to 13 fb at mH = 1 TeV for the vector-boson fusion production mechanism. The results from these four searches are also interpreted in the context of models beyond the SM, namely the Type-1 and Type-2 2 Higgs Doublet Model. The heavy Higgs boson search is also performed with the H → ZZ(*) → 4l decay mode alone using 3.2 fb⁻¹ of proton-proton collision data recorded during the second phase of LHC operation (Run-2) at an increased centre-of- mass energy of √s = 13 TeV. No significant excess of events over the Standard Model prediction is found. Upper limits are set on the heavy Higgs boson production cross-section times H → ZZ(*) → 4l branching ratio of 4.5 fb at mH = 200 GeV and 1 fb at mH = 1 TeV. Lastly, a project of a more technical character is presented. In this study, the scintillation detectors employed by ATLAS for triggering with minimal bias in the forward region, the Minimum Bias Trigger Scintillators (MBTS), are characterised. Due to material degradation caused by radiation damage in the early phases of LHC operation, the MBTS had to be replaced during the LHC shutdown taking place in 2014. Before installation in ATLAS, these detectors were characterised in appropriate laboratory facilities using cosmic radiation

Pełny tekst źródłaPrevious studies on place effect on health focused on the residential neighborhood. This approach was criticized for not considering non-residential geographic life environments. The overarching aim of this dissertation is to estimate whether accounting for people’s network of activity places and their resulting exposure allows improving the understanding of environmental influences on recreational walking behavior. Three cross sectional studies were conducted on the second wave of the RECORD Cohort Study. In the first study, I identified a typology of individuals’ patterns of mobility and related socio-demographic correlates. Results from the second study provide evidence that exposure to environmental characteristics supportive to walking highly differs between the residential neighborhood, the perceived residential neighborhood and the activity space. The measurement error resulting from the sole use of residential measures of exposure varies among SES groups and among categories of the degree of urbanicity of the residence. In the third empirical study a high density of destinations, the presence of a lake or waterway, and a high neighborhood education are associated with recreational walking. This dissertation strengthen the conceptual grounds and empirical evidence that accounting for both residential and non-residential geographical environments individual get exposed is required to better proxy the true environmental exposure, and to estimate environmental influences on health behaviors
