Li, Yingping. "Artificial intelligence and radiomics in cancer diagnosis." Electronic Thesis or Diss., université Paris-Saclay, 2022. http://www.theses.fr/2022UPASG053.
Full textArtificial intelligence (AI) has been widely used in the research field of AI-assisted diagnosis, treatment, and personalized medicine. This manuscript focuses on the application of artificial intelligence methods including deep learning and radiomics in cancer diagnosis. First, effective image segmentation is essential for cancer diagnosis and further radiomics-based analysis. We proposed a new approach for automatic lesion segmentation in ultrasound images, based on a multicentric and multipathology dataset displaying different types of cancers. By introducing the group convolution, we proposed a lightweight U-net network without sacrificing the segmentation performance. Second, we processed the clinical Magnetic Resonance Imaging (MRI) images to noninvasively predict the glioma subtype as defined by the tumor grade, isocitrate dehydrogenase (IDH) mutation and 1p/19q codeletion status. We proposed a radiomics-based approach. The prediction performance improved significantly by tuning different settings in the radiomics pipeline. The characteristics of the radiomic features that best distinguish the glioma subtypes were also analyzed. This work not only provided a radiomics pipeline that works well for predicting the glioma subtype, but it also contributed to the model development and interpretability. Third, we tackled the challenge of reproducibility in radiomics methods. We investigated the impact of different image preprocessing methods and harmonization methods (including intensity normalization and ComBat harmonization) on the radiomic feature reproducibility in MRI radiomics. The conclusion showed that ComBat method is essential to remove the nonbiological variation caused by different image acquisition settings (namely, scanner effects) and improve the feature reproducibility in radiomics studies. Meanwhile, intensity normalization is also recommended because it leads to more comparable MRI images and more robust harmonization results. Finally, we investigated improving the ComBat harmonization method by changing its assumption to a very common case that scanner effects are different for different classes (like tumors and normal tissues). Although the proposed model yielded disappointing results, surely due to the lack of enough proper constraints to help identify the parameters, it still paved the way for the development of new harmonization methods

Full textThe Afghan war (since 2001) may be seen as a new asymmetric conflict. It has all characteristics of the former asymmetric conflicts except territoriality, which has been replaced by ideology. Therefore, the battlefields have been displaced to the cognitive war. The distinction between war and peace became so small that it is now impossible to distinguish the law of war in regard to its intensity or to the implication of several states. The law of wars, due to its lack of adaptation stopped to ease the peace recovery, becoming a hindrance to combat. In consequence, some warriors have been tempted to use forbidden combat methods. Whose effects have been mediatized and took part of the western states legitimacy crisis (and questionning the World division in sovereign states). The lack of conflicts settlement could lead to a worldwide civil war. Unless, law of wars are harmonized through universal core rights mandatory for states and new international actors; a “World Parliament” could protect them. Furthermore, moral integrity of warriors is expected, it may be reflected into the military laws and their position into the civil society
Lamouroux, Raphaël. "Méthodes compactes d’ordre élevé pour les écoulements présentant des discontinuités." Thesis, Toulouse, ISAE, 2016. http://www.theses.fr/2016ESAE0035/document.
Full textFollowing the recent development of high order compact schemes such as the discontinuous Galerkin or the spectraldifferences, this thesis investigates the issues encountered with the simulation of discontinuous flows. High order compactschemes use polynomial representations which tends to introduce spurious oscillations around discontinuities that can lead to computational failure. To prevent the emergence of these numerical issues, it is necessary to improve the schemewith an additional procedure that can detect and control its behaviour in the neighbourhood of the discontinuities,usually referred to as a limiting procedure or a limiter. Most usual limiters include either the WENO procedure, TVB schemes or the use of an artificial viscosity. All of these solutions have already been adapted to high order compact schemes but none of these techniques takes a real advantage of the richness offered by the polynomial structure. What’s more, the original compactness of the scheme is generally deteriorated and losses of scalability can occur. This thesis investigates the concept of a compact limiter based on the polynomial structure of the solution. A monodimensional study allows us to define some algebraic projections that can be used as a high-order tool for the limiting procedure. The extension of this methodology is then evaluated thanks to the simulation of different 2D and 3D test cases. Those results have been obtained thanks to the development of a parallel solver which have been based on a existing unstructured finite volume CFD code. The different exposed studies detailed end up to the numerical simulation of the shock turbulent boundary layer

Full textThe LIGO Virgo collaboration marked the beginnings of gravitational astronomy by providing direct evidence of their existence in September 2015. The detection of gravitationnal wave coming from a binary black holes merger led to the physic's Nobel price. This field has since experienced a great growth, each discovery of which allows an advance in disciplines such as astrophysics, cosmology and fundamental physics. At the end of each observation period, the detectors are stopped and many aspects are improved. This work is part of the preparation phase between period O3 and O4 beginning in May 2024 to configure interferometers in their advanced states in order to optimize their sensitivities. Calibration then becomes crucial in order to accurately reconstruct the signal containing gravitational wave information, allowing detection and the production of scientific results such as the measurement of the Hubble constant, etc. An instrumentation work has been carried out, allowing an accurate and regular measurement of the time stamp (timing) of the readout sensing chain of the interferometer signal, which must be mastered better than 0.01 ms for the purpose of a joint analysis of the detectors network data.Many devices for the calibration of the interferometer rely on the reading of control signals by photodetectors whose frequency response has been assumed to be flat. In order to avoid any bias introduced in the reconstruction of the signal, a measurement method must be developed for a frequency calibration of each photo detector involved. Two methods are compared for use in the O5 period.In addition, the increasing sensitivity of the detectors means more detections. Collaboration analysis chains need to follow instrumental improvements by developing new tools to optimize real-time and off-ligne signal search. The MBTA Low Latency Analysis Chain is one of 4 collaboration analysis pipelines focusing on the search for compact binary coalescences by combining independent data analysis from all 3 detectors. It has many powerful noise rejection tools, but does not take into account any astrophysical information a priori. Through the accumulation of data in previous observation periods, the collaboration was able to establish more accurate mass distribution models for compact binary coalescence populations. During my thesis, a new tool was developed by the MBTA team using this new information, aimed at estimating the probability of origin of events (astrophysics or not) and at classifying the nature of the astrophysical source. This tool finally made it possible to restructure the global analysis chain by using it as the main parameter for classifying events according to their level of significance. The collaboration produces low-latency public alerts for multi-messenger astronomy, providing information related to detected signals common to the different analytical pipelines. Not knowing in advance the preferences of the different experiences partners of the LIGO Virgo collaboration to define the optimal parameters allowing multi-messenger detections, it was decided to test another method to implement similar astrophysical information in the MBTA analysis chain. A technique for including astrophysical information directly in the parameter defining the ranking by significance level of candidate events is presented. This method makes it possible to improve research by providing better discrimination between astrophysical and background noise events. By considering the observation period O3 this method makes it possible to increase the number of detection by 10% with MBTA , detections that have been confirmed by the other chains of analysis

Full textComputational Fluid Dynamics (CFD) solvers have reached maturity in terms of solution accuracy as well as computational efficiency. However, progress remains to be done for unsteady flows especially when governed by large, coherent structures. For these flows, current CFD solvers do not provide accurate solutions unless very fine mesh are used. Moreover, high-accuracy is a crucial feature for the application of advanced turbulence simulation strategies, like Large Eddy Simulation (LES). In order to apply high-order methods to complex unsteady flows several issues needs to be addressed among which numerical robustness and the capability of handling complex geometries.In the present work, we study a family of compact approximations that provide high accuracy not for each space derivative treated apart but for the complete residual r, i.e. the sum of all of the terms in the governing equations. For steady problems solved by time marching, r is the residual at steady state and it involves space derivatives only; for unsteady problems, r also includes the time derivative. Schemes of this type are referred-to as Residual-Based Compact (RBC). Precisely, we design high-order finite difference RBC schemes for unsteady compressible flows, and provide a comprehensive study of their dissipation properties. The dissipation and dispersion errors introduced by RBC schemes are investigated to quantify their capability of resolving a given wave length using a minimal number of grid-points. The capabilities of RBC dissipation to drain energy only at small, ill-resolved scales are also discussed in view of the application of RBC schemes to implicit LES (ILES) simulations. Finally, RBC schemes are extended to the Finite Volume (FV) framework in order to handle complex geometries. A high-order accuracy preserving FV formulation of the third-order RBC scheme for general irregular grids is presented and analysed. Numerical applications, including complex Reynolds-Averaged Navier-Stokes unsteady simulation of turbomachinery flows and ILES simulations of turbulent flows dominated by coherent structure dynamics or decay, support the theoretical results

Full textHigh-order numerical schemes are usually restricted to research applications, involving highly complex physical phenomena but simple geometries, and regular Cartesian or lowly deformed meshes. A demand exists for a new generation of industrial codes of increased accuracy. In this work, we were led to address the general question of how to design a CFD code architecture that: can take into account a variety of possibly geometrically complex configurations; remains simple and modular enough to facilitate the introduction and testing of new ideas (numerical methods, models) with a minimal development effort; use high-order numerical discretizations and advanced physical models. This required some innovative choices in terms of programming languages, data structure and storage, and code architecture, which go beyond the mere development of a specific family of numerical schemes. A solution mixing Python and Fortran languages is proposed with details on the concepts at the basis of the code architecture. The numerical methods are validated on test-cases of increasing complexity, demonstrating at the same time the variety of physics and geometry currently achievable with DynHoLab. Then, based on the computational framework designed, this work presents a way to handle complex geometries while increasing the order of accuracy of the numerical methods. In order to apply high-order RBC schemes to complex geometries, the present strategy consists in a multi-domain implementation on overlapping structured meshes

Full textCavitation-turbulence interactions are problematic aspect of cavitating flows which imposes limitations in development of better cavitation and turbulence models. DNS simulations with homogeneous mixture approach are proposed to overcome this and offer more insight into the phenomena. As DNS simulations are highly demanding and a variety of cavitation models exists, a tool devoted specifically to them is needed. Such tools usually demand application of highly accurate discretization schemes, direct solvers and multi domain methods enabling good scaling of the codes. As typical cavitating flow geometries impose limits on suitable discretization methods, compact finite differences offer the most appropriate discretization tool. The need for fast solvers and good code scalability leads to request for an algorithm, capable of stable and accurate cavitating flow simulations where solved systems feature multiplication of implicitly treated variables only by constant coefficients. A novel algorithm with such ability was developed in the scope of this work using Concus and Golub method introduced into projection methods, through which the governing equations for homogeneous mixture modeling of cavitating flows can be resolved. Work also proposes an effective and new approach for verification of the new and existing algorithms on the basis of Method of Manufactured Solutions
