Yu, Xiaoyang. "Dynamic acoustic emission for the characterization of the nonlinear behavior of complex materials". Thesis, Le Mans, 2020. http://www.theses.fr/2020LEMA1019.
Texto completoAcoustic emission (AE) is well known to be an efficient structural health monitoring technique to detect the creation and propagation of micro-cracks within structural materials such as concrete or composites when submitted to quasi-static stresses. Based on adequate signal processing methods, different research studies have established links between the detected AE hits and the created micro-damages. Other works have shown that it is possible to correlate the relaxation time in composites and the energy of the damage mechanisms measured during the quasi-static loading using the recorded AE hits. This thesis proposes to use an original experimental protocol to probe the nonlinear relaxation of concrete samples at the intact and damaged states. This protocol is based on the use of AE to passively probe the nonlinear relaxation of concrete samples instead of the weak amplitude signal usually used in slow dynamics experiments. Results show that passive and active probing methods lead to equivalent relaxation times. Furthermore, AE probing reveals the existence of a ‘silence period’ during the first minutes of the nonlinear relaxation after which AE hits start to be detected. In addition, the characteristics of AE hits recorded during the passive relaxation showed a clear resemblance to those obtained during the damaging of the same samples, where shear and compression mechanisms are involved. For the clustering of the AE hits, in addition to use of an unsupervised pattern recognition approach to cluster the detected AE hits, this work proposes a novel ‘image- based AE classification’ approach based on continuous wavelet transform (CWT) and convolutional neural network (CNN). Results related to the nonlinear dynamic and quasi-static AE data show that both signal processing approaches have high classification accuracy, which represents a great interest in the development of dynamic AE methods in the presence of micro-cracks

Texto completoAortic pressure is generally recognized as a good index of the hemodynamic state of a patient. In intensive care units, aortic pressure is indirectly estimated via a radial catheter-tansducer system. The present study aims to remove the obstacles to a reliable evaluation of central pressure via the radial catheter-transducer system commonly used in clinics. These obstacles can be due to :1.technical problems occurring between the radial catheter and the sensor;}2.pathophysiological problems affecting the arterial tree between the heart and peripheral arteries. Several clinical situations have been identified in which alterations of the physical properties of the vasculature do not allow a reliable estimation of central arterial pressure using the common radial setting. One of these phenomena is the so called central-to-radial arterial pressure gradient.CATARSI, a medical device developped by AII SAS, affords a solution to the first group of problems by providing an index of the quality of the signal provided by the radial catheter-transducer system.Under pathophysiological conditions affecting the arterial vascualture of the patient, early detection of a mismatch between peripheral and central arterial pressure would also be of great clinical value. In this view, a new functionality could be develop to implement CATARSI. However, to achieve this goal, it is first necessary to understand, evaluate and modelize the precise pathophysiological mechanisms involved in these particular situations.The study contains three steps :1.Experimental evaluation, by oscillometry and catheterization, of AP propagation-time on the human arterial tree (aortic, radial, femoral arterial pressure) during a central-to-radial arterial pressure gradient. This evaluation has been carried out on patients undergoing Cardio Pulmonary Bypass (CPB). Several measurements have been performed: before, during and after CPB.2.Development and optimization of a method allowing the detection of an uncoupling between central and peripheral arterial pressure thanks to AP signal analysis in real time and a potential complementary measurement performed with CATARSI.3.Several central to radial arterial modelling propositions in order to present a better evaluation of central arterial pressure estimated by radial arterial pressure

Texto completoThe main task of radars (Radio Detection and Ranging) is to detect targets and to determine their distance from the radar transmitter. They have been studied in numerous academic and industrial developments. These developments concern in particular onboard radars that are now being developed for several applications in consumer electronic devices. Recent developments in radar systems have been made possible thanks to advances in electronics, computing and signals processing. This thesis aims to contribute to the radar signal processing and particularly for applications related to collision avoidance systems. This work was developed along two main axes. On one hand, we have contributed to the study of radar waveforms constituted by pseudo-random sequences. In this context, we first examined the sequences presented in the literature by recalling their performance in terms of the merit factor, defined as the ratio between the energy of the main peak and the correlation of secondary lobes of the autocorrelation function. Given the difficulty of building very efficient waveforms constituted by sequences of contiguous symbols, we have considered then the use of Golay pairs, and more generally Golay sets, which have an infinite merit factor when they are separated by guard intervals. More generally, we have highlighted the good properties of their ambiguity functions. In particular, we have checked that the multipulse emission of Golay sequences allows good rejection of the ambiguity function side lobes, and very good estimation of the parameters of distance and relative speed of other vehicles. The second theme developed in this thesis concerns the rapid calculation of the cross-ambiguity function between a sent wave and the received echoes. This calculation makes it possible to simultaneously locate a set of targets in the time-frequency plane. In this context, we have studied Gauss-Legendre and Clenshaw-Curtis quadrature techniques, for which we have studied analytically the disturbances on the quadrature introduced by the fact that they must be calculated from sampled signals. In addition, with a view to reduce the computational complexity of the calculation of ambiguity functions, we have considered number theoretic transforms, and in particular Fermat number transforms, for which multiplications simply amount to bit shifts, leading thus to significant computational burden reduction

Texto completoThis thesis describes new tools specifically designed for the analysis of networks such as social, transportation, neuronal, protein, communication networks... These networks, along with the rapid expansion of electronic, IT and mobile technologies are increasingly monitored and measured. Adapted tools of analysis are therefore very much in demand, which need to be universal, powerful, and precise enough to be able to extract useful information from very different possibly large networks. To this end, a large community of researchers from various disciplines have concentrated their efforts on the analysis of graphs, well define mathematical tools modeling the interconnected structure of networks. Among all the considered directions of research, graph signal processing brings a new and promising vision : a signal is no longer defined on a regular n-dimensional topology, but on a particular topology defined by the graph. To apply these new ideas on the practical problems of network analysis paves the way to an analysis firmly rooted in signal processing theory. It is precisely this frontier between signal processing and network science that we explore throughout this thesis, as shown by two of its major contributions. Firstly, a multiscale version of community detection in networks is proposed, based on the recent definition of graph wavelets. Then, a network-adapted bootstrap method is introduced, that enables statistical estimation based on carefully designed graph resampling schemes

Texto completoIn this thesis, we focus on developing mathematical tools to treat a range of biological and economic signals. First, we propose the Dynalet transform for non-symmetrical biological relaxation signals. This transform is considered as an alternative to the Fourier transform and the wavelet transform. The applicability of the new approximation approach is illustrated on real data. Then, for spectrometric biological signals, we correct the baseline using a penalized expectile regression. Thus, the proposed applications show that our proposed regression is more efficient than the quantile regression. Then to remove random noise, we adapt to spectrometric data a new denoising method that combine wavelets, soft thresholding rule and PLS components. Finally, note that the biological signals may be often regarded as functional data. On one hand, we develop a functional local likelihood aiming to perform a supervised classification of curves. On the other hand, we estimate the regression operator with positive responses, by minimizing the mean squared relative error. Moreover, The asymptotic distributions of our estimator are established and their efficiency is illustrated on a simulation study and on a spectroscopic and economic data set
