Li, Xiaolin. "Numerical study to improve the effectiveness and accuracy of particle swarm optimization for structural damage detection of a cantilever beam". Electronic Thesis or Diss., Bourges, INSA Centre Val de Loire, 2021. http://www.theses.fr/2021ISAB0010.
Texto completoVibration-based based structural damage detection (SDD) is a typical inverse optimization problem. While the particle swarm optimization (PSO) has been used numerically or experimentally to solve this problem due to its simple concept, fast convergence, and few tuning parameters. However, there are still some drawbacks, such as premature convergence, time consumption, and inconsistent performance, which can deteriorate its damage detection results. This manuscript aims to improve the effectiveness and accuracy of particle swarm optimization (PSO) for structural damage detection (SDD). The main contributions can be summarized in three aspects. First, the two critical factors, fitness function and topology structure, which have significant impacts on the performance of the PSO in SDD, are investigated separately. Their respective simulation results in SDD of a cantilever beam verified that the ECBI-based fitness function is more favorable; the Four Cluster topology provides the best overall performance. Second, a multi-component framework is constructed and improved by combining several different PSO variants, allowing the particles to follow different search strategies in the optimization so that the advantages of each PSO variant can be exploited. In the improved version, the particles can self-regulate their search behavior based on their successful update rate in memory. Simulation results on multi-damage detection cases of the cantilever beam demonstrated the effectiveness of the framework and the superiority of the improved version. Thirdly, a two-stage approach that allows damage localization and quantification to be carried out separately was developed to address the time-consuming problem of PSO. Simulation results show that the proposed two-stage method provides faster convergence, less computation time, and better noise tolerance

Texto completoRalstonia solanacearum is a bacterial plant pathogen responsible of the bacterial wilt disease on more than 250 plant species including agronomical crops such as potatoes, tomato and peanuts. It has been reported several times in the literature, the emergence of new pathogenic variants successfully able to infect and induce bacterial wilt disease on previously described resistant plants. To understand the molecular basis of R. solanacearum adaptation to its host, an evolution experiment has been performed in my host team. R. solanacearum has been kept during more than 300 bacterial generations into the stem of several plant species (susceptible, tolerant and resistant plants). At the end of the experiment, the in planta fitness of the derived clones has been tested compared to the ancestral WT strain, and more than 80% of the derived clones had a better fitness. Among them, 50 clones were re-sequenced. Interestingly, 6 independent mutations were found in the same gene of unknown function (renamed efpR), this strongly suggesting an evolutionary parallelism. Reverse genetics approaches confirmed that efpR was involved in the in planta fitness gain. The goals of my thesis were (1) to characterize the function of the efpR gene and (2) to better understand its role in the fitness gain of the bacterium. To do so, transcriptomic and metabolic analysis were performed followed by phenotypic validations. We demonstrated that EfpR is a global regulator of R. solanacearum controlling metabolic and virulence functions. We also demonstrated that all the mutations appeared during the evolution experiment were "loss of function" mutations, these mutations also induced a phenotypic heterogeneity phenomenon. Indeed, 2 types of colonies were observable on plates, one type similar to the colonies formed by the WT strain and another type less mucoid. We also highlighted another gene, the RSc3149 gene which is an efpR homolog involved in the phenotypic heterogeneity. Finaly, most of the efpR related phenotypes were strikingly similar of those associated with a well described regulator of the bacterium, the PhcA major regulator. We performed transcriptomic analysis of both regulons coupled with reporter gene fusions analysis to understand if there was a link between these two regulons and if we could position efpR in the regulatory network of R. solanacearum.[...]

Texto completoThe cognitive decline that occurs during aging would be reduced by a high level of cardiorespiratory fitness. In this thesis, the underlying neurophysiological correlates of this prophylactic effect of cardiorespiratory fitness have been explored by near-infrared spectroscopy, which allows non-invasive measurement of cerebral hemodynamic activity. The objectives are firstly, to investigate the effects of task complexity, age and cardiorespiratory fitness level on the evolution of different indicators of cognitive performance, subjective perception of task difficulty and cerebral hemodynamic activity. Secondly, to examine the functional relationships that might exist between these different indicators. Throughout three experimental studies using different tasks involving executive control processes, whose level of complexity was manipulated, we measured these different indicators in young adults and seniors with high and low levels of VO2max. The results obtained showed that hemodynamic activity, cognitive performance and subjective perception of difficulty increase significantly as a function of the complexity of the cognitive tasks. This demonstrates the sensitivity of the different indicators to the manipulation of cognitive complexity. Furthermore, advancing in age induces a reduction in cognitive performance and hemodynamic activity but not in the subjective perception of difficulty. Also, our results indicated that cardiorespiratory fitness is linked to an increase in executive performance as well as in hemodynamic activity, only in seniors and for some tasks; the benefits being limited to the updating of working memory. Finally, the overall results have shown a possible link between hemodynamic activity and cognitive performance selective to young adults and seniors with a high level of VO2max when the experimental task is particularly complex; thus when the cognitive load is high. In sum, this work provides support for the understanding of the neurophysiological mechanisms underlying the prophylactic effects of cardiorespiratory fitness on the decline of the updating of working memory during normal aging

Texto completoIntroduction. Most childhood acute lymphoblastic leukemia (ALL) survivors develop chronic treatment-related adverse effects several years after the end of the treatment. Regular physical activity and a good cardiorespiratory fitness can decrease the risks of neurological disturbances and increase cognitive function scores. The aim of this study was to examine the preventive fraction of cardiorespiratory fitness and physical activity levels on cognitive functions. Methods. We enrolled 219 survivors of childhood ALL. The participants underwent a cardiopulmonary exercise test, neuropsychological tests of processing speed and executive functions (i.e. verbal fluency, cognitive flexibility, working memory) and completed a physical activity questionnaire. We calculated the odds ratio to obtain the preventive fraction of physical activity and cardiorespiratory fitness levels on cognitive functions. Results. The cohort is 52% male and 48% female. A total of 182 survivors (83%) have a cardiorespiratory fitness below their predicted (<100%). Our analyses show that there is an association between good cardiorespiratory fitness and processing speed (preventive fraction of 70% for dominant hand (p<0.01) and 65% for non-dominant hand (p<0.01)) and with cognitive flexibility identified as the category switching measure of the D-KEFS verbal fluency (preventive fraction of 61%; p<0.05). Conclusion. Good cardiorespiratory fitness (≥100% predicted value) and good levels of physical activity (≥150 min MVLPA/week) were associated to a preventive fraction for most cognitive function variables measured. Good cardiorespiratory fitness levels were significantly associated with a lower prevalence of poor performance in processing speed (i.e., dominant hand and non-dominant hand) and in cognitive flexibility (i.e., category switching) in childhood acute lymphoblastic leukemia survivors.

Texto completoThe relationship between cognitive function (CF), peak exercise parameters and cardiovascular risk factors has been poorly studied in obese subjects (OB). The goals of this study were: 1) to compare CF in higher-fitness and lower-fitness OB (HF-OB and LF-OB) vs. age-matched healthy controls (AMHC) according to their aerobic fitness level (V ̇O2peak) and 2) to find independent predictors of CF within the measured cardiovascular risk factors and peak exercise parameters. Forty nine OB and 14 AMHC were recruited. Maximal cardiopulmonary exercise test (with gas exchange analysis and impedance cardiography) was performed during an incremental ergocycle test. As well, CF was measured with a neuropsychological test battery. Obese subjects were divided into 2 groups according to the median V ̇O2peak divided by lean body mass (V ̇O2peak/LBM): the obese lower-fitness (LF-OB, n=22) and the obese higher-fitness (HF-OB, n=27). Cognitive flexibility, processing speed and short-term memory were not statistically different in HF-OB vs. AMHC and those two groups showed better performances in these domains when compared to the LF-OB group. The AMHC group performed better in tests measuring inhibition compared to the LF-OB and HF-OB groups. In summary, higher aerobic fitness in obese subjects was associated with preserved CF in every evaluated domains except for inhibition.
