Zhao, Yanqing. "Contributions à la détection précoce de chatter et à l’identification des bifurcations de période-N basée sur une approche de diagnostic cumulatif". Electronic Thesis or Diss., Université de Lorraine, 2020. http://www.theses.fr/2020LORR0250.
Cumulative diagnosis of dynamic systems requires the detection, identification, and characterization of incipient degradations. Its application to high-speed machining, for instance, could rely on period-N bifurcations phenomena analysis to detect and identify early-chatters and improve the quality of milling products and processes. Up to now, many efficient methods were proposed to detect early-chatter and identify period-N bifurcations. But these methods are struggling to implement these tasks reliably and accurately due to the complex nonlinear characteristics of their dynamic behaviors, the noise, and the variation of their operating conditions. The present thesis aims to develop and implement methods of early-chatter detection and period-N bifurcations identification within a real-time cumulative diagnosis approach. Aimed at early-chatter detection, we proposed three detection methods and one identification method for the cumulative diagnosis. The first method can be used to detect early-chatters remotely. The second one detects early-chatter quickly under specific operating and measuring conditions. However, in practice, the operating and measuring conditions are complex and variable. To adapt to different operating and measuring conditions, we proposed a third method, and the latter detects early-chatter reliably. It is also noted that in milling processes, the early-chatter can give rise to a bifurcation of period-N or Hopf type. The machining quality under the bifurcation process of the period-N type is less critical than that under the Hopf bifurcation type. To improve machining productivity and ensure the required machining quality, we can mill the workpiece under the condition of period-N bifurcations. Thus, it is compulsory to identify the early period-N bifurcations for improving machining productivity. For that purpose, we developed a method for identifying the type and size of the period-N bifurcations. We also proved the effectiveness of the proposed methods, using two benchmark milling process models. Besides, the proposed methods can be used for fault diagnosis of other dynamic systems, such as the pulse energy conversion systems or bearing or gearing systems

The goal of this thesis is to design useful statistical detection approaches to improve the aeroelastic flutter monitoring during the flight testing process. Flutter monitoring is investigated as a detection problem regarding the deviations of instability indicators. It consists of a combination of a subspace-based identification method to define a residual vector sensitive to a flutter indicator and a statistical CUSUM test for an on-line deviations monitoring with respect to a fixed reference value. This thesis proposes three approaches. The first performs a flutter detection with respect to a reference modal state predicted close to instability using the a priori knowledge of an aeroelastic model and/or experimental flight testing data. The second approach uses an adaptive flutter monitoring through updating the reference state during the on-line test. The third approach exploits detection tests for damping assessment with confidence bounds determination

Following the discovery of antibiotics, the therapeutic successes foreshadowed a future where infectious diseases of bacterial origin would be eradicated. However, in less than a century, the massive use of broad-spectrum antibiotics led to the emergence of resistance thus reducing therapeutic options. My research project aims to understand early bacterial metabolic and morphological changes induced by antibiotics and to contribute to the development of rapid and reliable diagnostic tests to promote the implementation of more targeted antibiotic treatments. By monitoring changes in various metabolic and morphological parameters of bacteria after antibiotic treatment, we have shown the interest of viability markers such as DiBAC4(3), TOPRO®-3 or Alexa FluorTM Hydrazide for rapid detection (<3h) of bacterial susceptibility to antibiotics. In particular, we have shown for the first time that protein carbonylation, which is induced under conditions of oxidative stress and cellular aging, is a universal early marker of bactericidal antibiotic susceptibility. Following this first part of the study, we wanted to understand the mechanisms involved in bacterial response to lethal stress caused by antibiotics. Following this first part of the study, we wanted to understand the bacterial mechanisms involved in response to lethal stress caused by antibiotics. In our experiments, it was observed that when the conditions no longer allowed the organism survival, a fluorescence signal intrinsically linked to the bacterium allowed to predict the fatal outcome after only 2 hours of incubation. Indeed, following a treatment with a bactericidal antibiotic targeting the synthesis of bacterial peptidoglycan (ampicillin), we observed a maximum fluorescence of the cells at the dose of antibiotic corresponding to the Minimum Inhibitory Concentration (MIC). The fluorescence increase of bacterial cells was also observed during the lethal treatment with a biocidal agent (sodium hypochlorite). However, this phenomenon is no longer observable with bacteriostatic or bactericidal antibiotics that inhibit protein synthesis indicating active bacterial metabolism importance. The correlations of spectral properties allowed us to suspect the flavin molecules as responsible for the observed autofluorescence phenomenon. In addition, we showed an overactivation of the biosynthesis pathway of flavin-type cofactors and flavoproteins occurring during ampicillin treatment. Finally, we performed cell sorting and cell survival experiments of ampicillin-treated bacterial populations. Our results showed that highly fluorescent cells have an average survival 5 times higher than low fluorescent cells. This suggests that the fluorescence signal observed is a cellular response mediated by flavonoid compounds in an attempt to survive to antibiotic treatment. Exploratory work suggests that the phenomenon studied in bacteria is conserved among yeasts and human cells. These results open new perspectives in bacterial physiology understanding, the study of bacterial response to exogenous stress and the rapid monitoring of cell viability

Stroke is the second leading cause of death and the leading cause of acquired disability in adults worldwide. Over the last twenty years, treatment in the acute phase of stroke has improved considerably. As a result, post-stroke mortality began to decline and the proportion of surviving patients with mild or moderate disabilities has increased. The long-term monitoring of this category of patients allowed to highlight, in a significant proportion of them, the occurrence of high psychological distress. These mood disorders significantly reduce post-stroke quality of life and, therefore, the assumption that put primary emphasis on the motor deficits, sensory or language now begins to move towards the psychological care of patients. These complications are however still insufficiently understood and their management remains unsatisfactory.In this context, the objective of this PhD was to better describe these post-stroke mood disorders and highlight, through objective measurement tools, the existence of risk factors for their occurrence. 91 patients were followed during one year after stroke and were evaluated on cognitive assessments, mood state evaluation, sleep recording and language recording. The results allowed us to better understand the involvement of some variables in the occurrence or progression of some mood disorders, for example sleep fragmentation and post-stroke apathy or affective prosody and post-stroke depression. Cerebellar lesions also appear to be related to the occurrence of post-stroke mood disorders. These results are part of the increasing research on post-stroke mood disorders

Despite the development of syndromic surveillance and of modern decision making methods, outbreak surveillance within hospitals remains mainly manual. Yet, the use of detection algorithms could improve surveillance efficiency, broaden its scope and overall reduce the time spent to accomplish this task. However, the methodological quality of the evaluations published to this date is too low to conclude about the real utility of these tools. We propose in this memoir several key elements of an adequate methodological framework for early outbreak detection, as well as a first data set containing labelled potential outbreaks. This data set can be used by researchers to develop, evaluate and compare detection algorithms. However, as research on surveillance systems and healthcare artificial intelligence tools has shown, implementing these tools can be difficult, and the results observed in real life can be quite different from those of the development phase. It is therefore necessary to use alternative indicators and evaluation methods to assess the real utility of these tools in real life, measuring for example their acceptability, ease of use, costs and impacts on daily practices
