Full textNuclear data allow to describe how a particle interacts with matter. These data are therefore at the basis of neutron transport and reactor physics calculations. Once measured and evaluated, they are given in libraries as a list of parameters. Before they can be used in neutron transport calculations, processing is required which includes taking into account several physical phenomena. This can be done by several softwares, such as NJOY, which all have the drawback to use old numerical methods derived from the same algorithms. For nuclear safety applications, it is important to rely on independent methods, to have a comparison point and to isolate the effects of the treatment on the final results. Moreover, it is important to properly master processing accuracy during its different steps. The objective of this PhD is then to develop independent numerical methods that can guarantee nuclear data processing within a given precision and to implement them practically, with the creation of the GAIA software. Our first step was the reconstruction of cross sections from the parameters given in libraries, with different approximations of the R-matrix theory. Reconstruction using the general formalism, without any approximation, has also been implemented, which has required the development of a new method to calculate the R-matrix. Tests have been performed on all existing formalisms, including the newest one. They have shown a good agreement between GAIA and NJOY. Reconstruction of angular differential cross sections directly from R-matrix parameters, using the Blatt-Biedenharn formula, has also been implemented and tested. The cross sections we have obtained at this point correspond to a target nucleus at absolute zero temperature. Because of thermal agitation, these cross sections are subject to a Doppler effect that is taken into account by integrating them with Solbrig's kernel. Our second step was then to calculate this integral. First, we have elaborated and validated a reference method that is precise but slow. Then, we have developed a new method based on Fast Fourier Transform algorithm. Comparisons with the reference method suggest that the precision of our method is better than the one achieved with NJOY, with comparable computation times. Besides, we have adapted this method to the case where target nuclei are in a condensed state (solid or liquid). For this latter case, an alternative implementation was done to obtain cross sections by integrating the S(a,b) law that characterize the chemical binding effect on collisions between neutrons and matter. Finally, a method was developed to generate an energy grid fine enough to allow a linear interpolation of cross sections between its points. At this point, we have at our disposal the minimum amount of information required to produce input files for the Monte-Carlo transport code MCNP. Such data have been translated into the correct format thanks to a module of NJOY. Calculations have been performed using our input files on several configurations, to demonstrate that our methods can actually be used to process modern evaluated files. In parallel, as part of a collaboration with Institut Laue-Langevin, we have participated in the treatment of experimental measurements of the S(a,b) law for light and heavy water. With GAIA, we have combined experimental values with values from a molecular dynamics simulation, with the objective to avoid using a molecular model in the domain where experimental values are available. This has only been a first step, but the values obtained improves the predictions of the model of ILL reactor. As a conclusion, during this PhD, new numerical methods were developed and we have shown that they can be used in practical cases

Full textThe time-harmonic Maxwell’s equations present several difficulties when the frequency is large, such as the sign-indefiniteness of the variational formulation, the pollution effect and the problematic construction of iterative solvers. We propose a precise and efficient solution strategy that couples high order finite element (FE) discretizations with domain decomposition (DD) preconditioners. High order FE methods make it possible for a given precision to reduce significantly the number of unknowns of the linear system to be solved. DD methods are then used as preconditioners for the iterative solver: the problem defined on the global domain is decomposed into smaller problems on subdomains, which can be solved concurrently and using robust direct solvers. The design, implementation and analysis of both these methods are particularly challenging for Maxwell’s equations. FEs suited for the approximation of the electric field are the curl-conforming or edge finite elements. Here, we revisit the classical degrees of freedom (dofs) defined by Nédélec to obtain a new more friendly expression in terms of the chosen high order basis functions. Moreover, we propose a general technique to restore duality between dofs and basis functions. We explicitly describe an implementation strategy, which we embedded in the open source language FreeFem++. Then we focus on the preconditioning of the linear system, starting with a numerical validation of a one-level overlapping Schwarz preconditioner, with impedance transmission conditions between subdomains. Finally, we investigate how two-level preconditioners recently analyzed for the Helmholtz equation work in the Maxwell case, both from the theoretical and numerical points of view. We apply these methods to the large scale problem arising from the modeling of a microwave imaging system, for the detection and monitoring of brain strokes. In this application accuracy and computing speed are indeed of paramount importance

Full textThe continuous evolution of manufacturing environments and the growing of customer needings, leads to a faster and more efficient production process that controls an increasing number of parameters. This thesis is focused on the development of decision making methods in order to improve the production scheduling. The industrial partner (Norelem) produces standardized mechanical elements, so many different resource constraints (humans and tools) are presented in its workshop.We study an open shop scheduling problem where one job can follow multiple production sequences because there is no fixed production sequence and the objective function is to minimize the total flow time. In addition, multi-skilled personnel assignment and tool’s availability constraints are involved.Mathematical models: linear and non-linear formulations have been developed to describe the problem. Knowing the exact method limitations in terms of instance sizes because of the duration, heuristics methods have been proposed and compared. Besides that, the multi-objective optimization was exposed to deal with three objectives as total flow time minimization and workload balancing concerning both, humans and machines.The efficiency of these methods was proved by several theoretical instance tests and the application on the real industrial case

Full textThe thesis presents a complete methodology for creating Conformance Test Suites for programming languages, libraries and APIs, with a special attention to parallel and distributed programming libraries. Author has started his research in the field of conformance testing for parallel and distributed programming libraries, but methodology Consecutive Confinements Method (CoCoM), invented by Author, turned out to be general enough to be applied to a wider class of programming libraries, languages and APIs, including both sequential and non-sequential programming models based on imperative programming paradigm. Methodology CoCoM is based on notions defined in the international standard ISO/IEC 13210: Information Technology , - Requirements and Guidelines for Test Methods Specifications and Test Method Implementations for Measuring Conformance to POSIX Standards, and attempts to extend it. CoCoM can be seen as a framework, where many different methodologies and tools can be incorporated, allowing for expansion towards any specific formalism, for which a supporting processing engine can be found. For the purpose of the Thesis Author has developed a prototype tool called CTS Designer, which implements significant parts of the standard ISO/IEC 13210 and the CoCoM methodology and shall be considered a top integrating component of a dedicated formal framework postulated before

Full textThe goal of this thesis is to solve in practice the coverability problem in Petri nets and lossy channel systems (LCS). These systems are interesting to study because they can be used to model concurrent and distributed systems. The coverability problem in a transition system is to decide whether it is possible, from an initial state, to reach a greater state than a target state. In the first part, we discuss how to solve this problem for well-structured transition systems (WSTS). Petri nets and LCS are WSTS. In the first part, we present a general method to solve this problem quickly in practice. This method uses coverability invariants, which are over-approximations of the set of coverable states. The second part studies Petri nets.We present comparisons of coverability invariants, both in theory and in practice. A particular attention will be paid on the combination of the classical state inequation and a simple sign analysis. LCS are the focus of the third part. We present a variant of the state inequation for LCS and two invariants that compute properties for the order in which messages are sent. Two tools, ICover and BML, were developed to solve the coverability problem in Petri nets and LCS respectively

Full textThis general objective of this study is the development and assesment of efficient time integration scheme for Discontinuous Galerkin time domain (DGTD) method on unstructured tetraedral meshes for numerical resolution of Maxwell equations. In first part of this thesis, we remind Maxwell's equations and summarize main numerical methods used to solve this system. In the second part, we present the Discontinuous Galerkin method based on centred approximations for generic order. In this chapter, we focuse to time explicit scheme. We detailed, in third chapter, the main part of this work, in other words time implicit scheme, especially the Crank-Nicolson scheme, which is most studied in scientific litterature and in a second time a scheme of order 4 obtained by the defect correction technique. We realized a comparative study of both solvers (iterative and direct) to solve the linear system in chapter 4. For a memory space consideration , we apply the implicit scheme on a subdomain only. To do this, we use a hybrid explicit/implicit scheme. On chapter 6, we present the results 3D obtained with this method. Problems considered has several millions unknowns

Full textIn this thesis, we are concerned with the numerical resolution of the problem of acoustic waves scattering by an obstacle in dimensions 2 and 3, with the boundary element method. In the first three chapters, we consider objects with singular geometries. We focus on the case of objects with edge singularities, first open curves in the plane, and then open surfaces in dimension 3. We present a formalism that allows to restore the good properties that held for smooth objects. A weight function is defined on the scattering object, and the usual layer potentials (single-layer and hypersingular) are adequately rescaled by this weight function. Suitable preconditioners are proposed, that take the form of square roots of local operators. In dimension 2, we give a complete theoretical and numerical analysis of the problem. We show in particular that the weighted layer potentials belong to a class of pseudo-differential operators on open curves that we define and analyze here. The pseudo-differential calculus thus developed allows us to compute parametrices for the weighted layer potentials, which correspond to the continuous versions of our preconditioners. In dimension 3, we show how those ideas can be extended theoretically and numerically, for the particular case of the scattering by an infinitely thin disk. In the last chapter, we present a new method for the rapid evaluation of discrete convolutions by radial functions in dimension 2. Such convolutions represent a computational bottleneck in the boundary element methods. Our algorithm relies on the non-uniform fast Fourier transform and generalizes to dimension 2 an analogous algorithm available in dimension 3, namely the sparse cardinal sine decomposition
