Full textThe subject of this thesis is part of fault tolerant control systems under constraints with consideration of performance degradation. The main objective of this work is to consider the reference management as an integral part of the fault tolerant control system. In the literature, the most active methods of fault tolerance imply that recovery of the nominal system is always possible and that performance ratings are still achievable. This requirement is unrealistic in practice because several factors prevent the system reconfigured back to its nominal operating mode. In industry, the set of system constraints is a major problem which limits the nominal operating of the system to defined functional ranges. These functional ranges are reduced dramatically after the occurrence of some faults known as severe faults that generally affect the capacity of actuators. Therefore, this assumption of nominal performance recovery in the case of systems under constraints limits the set of faults treated with these conventional methods to a few minor faults. To remedy this problem, architecture of reconfiguration structured in two levels is proposed. The first level concerns the conventional reconfiguration algorithms acting on a reconfigurable controller, and the second acts on the module of reference management based on a reference-offset governor. The exact knowledge of the post-fault model requires a fault detection and diagnosis system to estimate the magnitude of fault, which led to the synthesis of an adaptive observer based LMI for estimating fault. To synchronize the FTC process flow, two indices have been designed. The first index refers to the decision mechanism for selecting the reconfiguration level required for the accommodation of the fault. The second index used to evaluate the level of the degradation of the system "post-fault". The performance degradation is still allowed as long as safety instructions are respected

Full textIn human medicine, plasma plasma homocysteine concentration is a biomarker used for early diagnosis of cobalamin or folate deficiencies, and cardiovascular risk assessment in some medical conditions such as chronic kidney failure. ln veterinary medicine, several studies are beginning to address the status of homocysteine in diseased animals. The first objective of our study was to define the biological determinants and the reference interval of plasma homocysteine concentration in healthy adult cats, after having verified the concentration validity of the high-performance liquid chromatography - tandem mass spectrometry method. Our work confirmed the suitability of this technique for the measurement of homocysteine in feline plasma. The study of plasma homocysteine concentrations in healthy cats provided a particularly wide reference interval, showing high inter-individual variability that we were not able to explain by epidemiological determinants. We described an influence of the dietary protein content and plasma creatinine concentration. A strong metabolic signature was identified in a group of animals with elevated plasma homocysteine concentrations, suggesting alterations in the homocysteine metabolism in some healthy cats. The second aim of our work was to compare plasma homocysteine concentrations between a population of cats with stable chronic kidney disease and the previously established population of healthy individuals. This study of a small number of cats with chronic kidney disease did not show any differences from the reference population

Full textThe aim of this thesis is to study how group identification may lead to better cognitive performance, based on social identity theory (Tajfel & Turner, 1986). This theory states that the social identity of individuals is partly based on comparison of their group with another group. The search for a positive social identity should drive individuals to act on behalf of their own group, putting them in an advantageous position compared to another group. The SIDE Model (Social Identity model of Deindividuation Effects, Reicher, Spears & Postmes, 1995) extends this theory by postulating that anonymity could facilitate the transition from personal to social identity, which is reinforced in the process. Our study was organized along three lines of research. The first two examined how anonymity and intergroup comparison affects performance on computer quizzes and statistics exercises in a web-based learning environment. The third studied the effects of anonymity and intergroup comparison on the generation of creative ideas in the presence of others. Consistent with the SIDE Model, we found that intergroup comparison under anonymity conditions activated group members’ social identity, leading to better performance on cognitive tasks. We also found that individual differences, such as prior knowledge, may moderate the effects of the SIDE model. The practical and theoretical implications of these results are discussed, and future research directions are suggested

Full textThe objectif of motor learning consist in a modification of answering motor pattern; quantitative and qualitative evaluation of transformations due to intervention strategy is a particularly hard task. Most of the procedures in athletics throws did not have a strict experimental validation. Very often they are a testimony of the teacher’s representations and expectations. Sometimes they consist in real believes. The numerous informations we have collected all along the process, on a lot of PE and sports students, have led us to a better conception of the phenomenon. We have been able to quantify the improvement of subjects learning javelin throw, on both normative and singular view. Thus we have been in a position to prove that, on first stage of learning process, performance depends on time committment in motor skill. The existence of a prediction equation showing a strong determination coefficient allows the illustration of this connection, as much with men and women. However the shapes of the curves demonstrates the existence of disparities since we perceive accelerations, stagnations, and regressions that can be explained only by a causal analysis. The statistics analysis allows to delimitate, for a certain number of hypotheses, the existence of a validity space when they don’t allow to refute the pertinence of certain points of view; they suggest some economics and reliable evaluation protocoles that rely on proved facts. We think that study could serve as an example, not only for the approach that other disciplines could adopt, but even for the general knowledge of motor learning

Full textOver the last few years, a significant growth is observed for OLEDs (Organic Light-Emitting Diodes) resulting in the gradual integration into many electronic devices for mass-market applications: smartphones, touchscreen tablet, TV … However, despite many advantages, the high sensitivity of the organic stacks in ambient atmosphere, and the surface degradation of the devices, are the main causes limiting the massive use of this technology. The encapsulation of the devices thanks to barrier multilayers can solve some or all these problems. The aim of this thesis is to develop and to characterize new inorganic-organic multilayers as a barrier against moisture and oxygen, in order to preserve OLEDs performances. Solutions for the thin layer encapsulation, made directly in the surface of the devices, have been developed and evaluated on OLEDs. The encapsulation stacks are based on alternating between a film of aluminum oxide deposited by ALD (Atomic Layer Deposition) and a layer of organic resin. Stacks of OLEDs are fragile, and the deposits have been carried out under mild conditions, especially when temperatures are low (T < 100 °C). A the same time, a method for the characterization of the barrier properties has been carried out, in order to evaluate the intrinsic performances of thin films or encapsulation stacks used, and to provide an understanding of the protection mechanism

Full textOur study aims to propose a methodology and tools which facilitate the internal benchmarking. This approach aims to share good practices between two business processes. In the first chapter, we show the evolution of industrial performance. In the past, we focused on the production cost reduction and now our actions must more and more improve our business processes regarding four characteristics: a global, perennial, relevant and accelerated performance. We also explain that the present progress approaches can not simultaneously satisfy these four stakes. In the second chapter, we expose the benchmarking evolution which passed from a business process results comparison to an identification of good practices at the origin of performance. We try to define “good practice” with the help of Knowledge Management discipline and explain the difficulty for a company to identify it. We also show that the present benchmarking models, which are proposed in the literature, can not help most companies to share easily good practices. So, that' s the reason why we propose in the third chapter a methodology and tools which concerne especially three steps of benchmarking: the process description, the processes comparison and the good practices deployment. We finish the study with an application in TECUMSEH company. The fourth chapter shows an internal benchmarking between two plants regarding "Six Sigma" process

Full textTar sands beneficiation requires a series of processing steps for separation of bitumen, water and sand particles. In this process, hydrocyclones are used to separate sand from water and bitumen, thereby recovering additional bitumen and concentrating sand particles before sending them off to tailing ponds. In order to reduce fresh water consumption (environmental policy), hydrocyclones need to operate with high feed solids content, say 50% in mass, which lays outside their standard operating regime. The response and performance of hydrocyclones need to be understood under such stringent operating conditions. A pilot scale experiment was commissioned for testing a 100mm diam. hydrocyclone under different operating regimes of discharge and measuring the corresponding separation performance. Feed solids concentration and geometrical properties were varied extensively. Separation performance indicators, including partition curve, cut-size, sharpness index and water recovery to underflow were obtained by standard data reconciliation. The experimental data provided all the information required to test the CFD model that was derived to simulate the hydrocyclone. Eulerian simulations of the three-dimensional liquid-solid flow inside the hydrocyclone were carried out, using a multi-fluid model (NEPTUNE_ CFD@Tlse). The actual geometrical features and operating conditions of the hydrocyclone were accurately matched in the simulations. Two simulation approaches have been proposed for hydrocyclone modelling, depending on their operating under dilute conditions, with a spray discharge or dense conditions, with a rope discharge. Numerical simulation results are in good agreement with experiments. Local analysis of hydrodynamic features yields new insights into the behaviour of hydrocyclones at high feed solids concentration
