Zhong, Anruo. „Machine learning and adaptive sampling to predict finite-temperature properties in metallic materials at the atomic scale“. Electronic Thesis or Diss., université Paris-Saclay, 2024. http://www.theses.fr/2024UPASP107.
Der volle Inhalt der QuelleThe properties and behaviors of materials under extreme conditions are essential for energy systems such as fission and fusion reactors. However, accurately predicting the properties of materials at high temperatures remains challenging. Direct measurements of these properties are constrained by experimental instrument limitations, and atomic-scale simulations based on empirical force fields are often unreliable due to a lack of accuracy. This problem can be addressed using machine learning techniques, which have recently become widely used in materials research. Machine learning force fields achieve the accuracy of ab initio calculations; however, their implementation in sampling methods is limited by high computational costs, typically several orders of magnitude greater than those of traditional force fields. To overcome this limitation, this thesis has two objectives: (i) developing machine learning force fields with a better accuracy-efficiency trade-off, and (ii) creating accelerated sampling methods to facilitate the use of computationally expensive machine learning force fields and accurately estimate free energy. For the first objective, we enhance the construction of machine learning force fields by focusing on three key factors: the database, the descriptor of local atomic environments, and the regression model. Within the framework of Gaussian process regression, we propose and optimize descriptors based on Fourier-sampled kernels and novel sparse points selection methods for kernel regression. For the second objective, we develop a fast and robust Bayesian sampling scheme for estimating the fully anharmonic free energy, which is crucial for understanding temperature effects in crystalline solids, utilizing an improved adaptive biasing force method. This method performs a thermodynamic integration from a harmonic reference system, where numerical instabilities associated with zero frequencies are screened off. The proposed sampling method significantly improves convergence speed and overall accuracy. We demonstrate the efficiency of the improved method by calculating the second-order derivatives of the free energy, such as the elastic constants, which are computed several hundred times faster than with standard methods. This approach enables the prediction of the thermodynamic properties of tungsten and Ta-Ti-V-W high-entropy alloys at temperatures that cannot be investigated experimentally, up to their melting point, with ab initio accuracy by employing accurate machine learning force fields. An extension of this method allows for the sampling of a specified metastable state without transitions between different energy basins, thereby providing the formation and binding free energies of defective configurations. This development helps to explain the mechanism behind the observation of voids in tungsten, which cannot be explained by existing ab initio calculations. The free energy profile of vacancies in the Ta-Ti-V-W system is also computed for the first time. Finally, we validate the application of this free energy sampling method to liquids. The accuracy and numerical efficiency of the proposed computational framework, which combines machine learning force fields and enhanced sampling methods, opens up numerous possibilities for the reliable prediction of finite-temperature material properties

Der volle Inhalt der QuelleThis study deals with the development of hardware and software tools to estimate and improve the efficiency of the PV energy conversion chain for household photovoltaic applications. We firstly proposed a new mixed 5-level inverter. This type of structure, based on the mixture of a full bridge inverter and NPC architecture, reduces the converter output voltage THD while reducing levels of leakage current induced by the PV modules. This architecture consists of a limited number of semiconductor devices with respect to a NPC structure and improves the robustness of the inverter. Several test results in reduced power validate the concept proposed. Finally, we focus on some parameters that could perturb the system and impact the energy production. It is highlighted that the impact of the convective heat transfer coefficient variation with wind speed is important. For this purpose, a flexible tool was developed to estimate the PV production. It is then possible to quantify and qualify the impact of wind speed on the photovoltaic energy production

Der volle Inhalt der QuelleThis thesis, containing four chapters, studies the existence, uniqueness and regularity of the solutions of the Primitive Equations (PEs) of the oceans and the atmosphere in space dimensions 2 and 3 (Chapters 1--3), and also the asymptotic behavior of the PEs when the Rossby number goes to zero (Chapter 4); the boundary conditions considered here are periodical. In the first chapter, we consider the PEs of the ocean in a two-dimensional space (three dimensional motion independent of the y variable). We prove the existence, globally in time, of a weak solution and the existence and uniqueness of strong solutions. Moreover, we prove the existence of more regular solutions, up to C-infinity regularity. In the second chapter, for a model similar to the previous one, we prove that, for a forcing term which is analytical in time with values in a Gevrey space, the solutions of the PEs starting with the initial data in a certain Sobolev space become, for some positive time, elements of a certain Gevrey class. As a natural continuation of the work from the first two chapters, in the third chapter we consider the PEs in a 3D domain and we study the Sobolev and Gevrey regularity for the solutions. The last chapter of the thesis is devoted to the study of the asymptotic behavior when the Rossby number goes to zero, for the PEs in the form considered in the first chapter. The aim of this work is to average, using the renormalization group method, the oscillations of the exact solution when the Rossby number goes to zero, and to prove that the averaged solution is a good approximation of the exact oscillating solution
