Testo completoAssessing the risk of musculoskeletal disorders in industrial environments is a challenging task, given the complexity of modern manufacturing processes. These environments include various factors influencing operator activity, such as organizational, managerial and environmental elements, as well as the pace of work. Assessing the physical constraints to which operators are subjected is crucial to preventing these disorders. Although many systems currently monitor operator movements and assess postural constraints to provide an overview of physical activity, they often fail to analyze the physical forces experienced or generated by the operator. Consequently, it is essential to quantify these forces in order to identify effort-related physical risk factors. However, conventional measurement methods are often complex, invasive and impractical in industrial environments. This thesis addresses these challenges by evaluating learning approaches for estimating physical stresses without resorting to invasive measurements, which is fundamental to improving ergonomic tools and practices. We began by comparing the accuracy and robustness of computer vision-based measurement systems for RULA assessment, focusing particularly on on-site ergonomic evaluations. Our analysis focused primarily on the evaluation of computer vision-based systems, including those with one or more cameras, using RGB or depth images, and systems that rely solely on visual data or incorporate wearable sensors (hybrid systems). Next, we developed and evaluated several learning architectures designed to emulate the inverse dynamics step in motion analysis. These predict joint torques from the operator’s skeletal data and the weight and mass of the load carried, thus offering a new alternative to classical inverse dynamics methods. Finally, we examined the generalizability of deep learningbased tools, such as OpenCap, in industrial tasks. Using fine-tuning - a common technique in deep learning for adapting models to new data sets with minimal samples - we sought to adapt OpenCap’s learning models to a new type of motion and a new set of markers

Testo completoThe restoration problem is usually encountered in various domains and in particular in signal and image processing. It consists in retrieving original data from a set of observed ones. For multidimensional data, the problem can be solved using different approaches depending on the data structure, the transformation system and the noise. In this work, we have first tackled the problem in the case of discrete data and noisy model. In this context, the problem is similar to a segmentation problem. We have exploited Pairwise and Triplet Markov chain models, which generalize Hidden Markov chain models. The interest of these models consist in the possibility to generalize the computation procedure of the posterior probability, allowing one to perform bayesian segmentation. We have considered these methods for two-dimensional signals and we have applied the algorithms to retrieve of old hand-written document which have been scanned and are subject to show through effect. In the second part of this work, we have considered the restoration problem as a blind source separation problem. The well-known "Independent Component Analysis" (ICA) method requires the assumption that the sources be statistically independent. In practice, this condition is not always verified. Consequently, we have studied an extension of the ICA model in the case where the sources are not necessarily independent. We have introduced a latent process which controls the dependence and/or independence of the sources. The model that we propose combines a linear instantaneous mixing model similar to the one of ICA model and a probabilistic model on the sources with hidden variables. In this context, we show how the usual independence assumption can be weakened using the technique of Iterative Conditional Estimation to a conditional independence assumption

Testo completoThis research work proposes the development and the validation of an online and real-time method to predict the remaining service life of the gearwheels of automotive transmissions, with the aim of implementing it on standard control units of series-production vehicles. By focusing on the proposition of a simple, reliable and easy-to-implement solution, the system relies on the combination of an acquisition method of the torques acting in the transmission and a continuous estimation of the damage levels of the gearwheels. Firstly, a state of the art and the theoretical basics are presented concerning a damage estimation based on a nominal stress concept and a linear damage accumulation. The global structure of the damage estimation algorithm is then analyzed and the methodological approach adopted for its development is explained. This is based in principal on a drivetrain model, validated with tests and measurements, where a particular attention is paid to the representation of the gear shifts and the transmission dynamics. Two types of transmissions are considered, namely a standard manual transmission and a dual clutch transmission mounted in series-production cars. Respectively a requirement analysis for the configuration of the algorithm as well as a requirement specification for the torque acquisition method are performed. On this basis, a state observer is developed and validated, which is able to reconstruct the clutch torque and the transmission output torque. Finally, a synthesis of the complete method and the final version of the algorithm are addressed, and the economic and ecological advantages of the introduction of the method in the context of lightweight design measures are discussed and evaluated
Kurzfassung Diese Dissertation beschreibt die Entwicklung einer Online- und Echtzeit-Methode zur Vorhersage der restlichen Lebensdauer von den Zahnradern eines Kraftfahrzeuggetriebes. Diese Methode ist fur eine Implementierung auf Standard-Steuergeraten vorgesehen. Durch die Fokussierung auf eine einfache, zuverlassige und leicht zu implementierende Losung beruht die Methode auf der Kombination aus einer Drehmomenterfassungsmethode und einer kontinuierlichen Vorhersage des Schadigungsniveaus der Zahnrader. Zuerst werden der Stand der Technik und die theoretischen Grundlagen von Schadigungsberechnungen basierend auf dem Nennspannungskonzept und einer linearen Schadensakkumulation dargestellt. Danach wird die globale Struktur des Schadigungsberechnungsalgorithmus gezeigt und die fur die Entwicklung ausgewahlte methodische Vorgehensweise erlautert. Diese bezieht sich grundsatzlich auf ein durch Testfahrten und Messungen verifiziertes Antriebsstrangmodell, welches besonders die Schaltungen und die Dynamik des Getriebes berucksichtigt. Ein Serien-Handschaltgetriebe und ein Serien-Doppelkupplungsgetriebe werden betrachtet. Fur diese zwei Getriebetypen werden eine Anforderungsanalyse zur Konfiguration des Algorithmus sowie eine Anforderungsspezifikation fur die Drehmomenterfassungsmethode durchgefuhrt. Auf Basis dieser Untersuchungen wird dann ein Zustandsbeobachter zur Rekonstruktion des Kupplungs- und Getriebeausgangsdrehmoments entwickelt und validiert. Infolgedessen werden eine Synthese der kompletten Methode und die Endversion des Algorithmus vorgestellt. Abschliesend werden die Wirtschaftlichkeit sowie die okologischen Vorteile in Bezug auf die Einfuhrung der Lebensdauermonitoringmethode im Rahmen von Leichtbaumasnahmen diskutiert und bewertet

Testo completoHidden Markov chains (HMCs) based approaches have been shown to be efficient to resolve a wide range of inverse problems occurring in image and signal processing. In particular, unsupervised segmentation of data is one of these problems where HMCs have been extensively applied. According to such models, the observed data are considered as a noised version of the requested segmentation that can be modeled through a finite Markov chain. Then, Bayesian techniques such as MPM can be applied to estimate this segmentation even in unsupervised way thanks to some algorithms that make it possible to estimate the model parameters from the only observed data. HMCs have then been generalized to pairwise Markov chains (PMCs) and triplet Markov chains (TMCs), which offer more modeling possibilities while showing comparable computational complexities, and thus, allow to consider some challenging situations that the conventional HMCs cannot support. An interesting link has also been established between the Dempster-Shafer theory of evidence and TMCs, which give to these latter the ability to handle multisensor data. Hence, in this thesis, we deal with three challenging difficulties that conventional HMCs cannot handle: nonstationarity of the a priori and/or noise distributions, noise correlation, multisensor information fusion. For this purpose, we propose some original models in accordance with the rich theory of TMCs. First, we introduce the M-stationary noise- HMC (also called jumping noise- HMC) that takes into account the nonstationary aspect of the noise distributions in an analogous manner with the switching-HMCs. Afterward, ML-stationary HMC consider nonstationarity of both the a priori and/or noise distributions. Second, we tackle the problem of non-stationary PMCs in two ways. In the Bayesian context, we define the M-stationary PMC and the MM-stationary PMC (also called switching PMCs) that partition the data into M stationary segments. In the evidential context, we propose the evidential PMC in which the realization of the hidden process is modeled through a mass function. Finally, we introduce the multisensor nonstationary HMCs in which the Dempster-Shafer fusion has been used on one hand, to model the data nonstationarity (as done in the hidden evidential Markov chains) and on the other hand, to fuse the information provided by the different sensors (as in the multisensor hidden Markov fields context). For each of the proposed models, we describe the associated segmentation and parameters estimation procedures. The interest of each model is also assessed, with respect to the former ones, through experiments conducted on synthetic and real data
