Zaier, Mayssa. "Context-aware pedestrian behavior agentification using innovative deep learning methods on video and 3D data". Electronic Thesis or Diss., Ecole nationale supérieure Mines-Télécom Lille Douai, 2024. http://www.theses.fr/2024MTLD0007.
Testo completoPedestrian trajectory prediction has gained increasing attention due to its importance in applications such as autonomous vehicles and urban surveillance systems. The objective of this thesis is to develop innovative models for predicting pedestrian trajectories relying on mainly video and 3D data acquired in particular on conflict zones, namely zones where traffic lanes are shared between pedestrians and other users. First, we introduce an attention-based model that leverages dynamic scene context and a bimodal transformer network to enhance spatio-temporal interaction modeling. To tackle the complex challenge of 3D human motion prediction, we propose a novel model capable of predicting 3D skeleton poses from 2D observations. This approach utilizes an encoder-decoder architecture, combining transformer networks and LSTMs to effectively model human motion. We then extend our model to predict multi-pedestrian trajectories by integrating Generative Adversarial Networks (GANs) with sequence prediction techniques, incorporating both social interactions and environmental context. Furthermore, we present a robust framework to represent pedestrian poses in geometric space for 3D human motion prediction. This involves exploring geometric attention models to provide deeper insights into spatial relationships and motion prediction. Our proposed models, the Motion-Lie Transformer and Kendall Manifold Transformer, employ Lie algebra representations and geometry-aware deep learning techniques, respectively. Extensive experiments conducted on several public datasets demonstrate that our models outperform traditional trajectory prediction and pose estimation methods, even in highly dense scenarios. Additionally, the approach can be integrated into autonomous driving systems to enhance pedestrian safety by improving the prediction of future movements. Lastly, this thesis examines the current limitations of trajectory/motion prediction in urban environments and proposes potential improvements to address more complex scenarios, including unpredictable pedestrian behavior
Desrumaux-Zagrodnicki, Pascale. "Explications causales et engagement contre ou pro attitudinal : de l'internalité aux conduites pro-attitudinales". Lille 3, 1996. http://www.theses.fr/1996LIL30024.
Testo completoThe thesis examines the conditions under which certain cognitions, relating to a person's feeling of control and responsability, influence behaviour. It brings together two theoretical fields of cognitive social psychology, causal explanations of reinforcement (locus of control) and of behaviours (attribution), on the one hand, and the theories on behaviour patterns and behaviour rationalization (commitment and cognitive dissonance), on the other. The hypothesis mat the processes of internal and external explanations influence behaviour and subsequent attitude change is interpreted in a new light, distinguishing between behaviours and contrasting attitudes : the experimental part begins by experimenting with and comparing different methods for activating causal explanatory processes. It then proceeds to experiment with the effect of causal explanatory processes, wether activated or not, on pro and counterattitudinal commitment. Counter-attitudinal requests (re. Trade-unionism) trigger a heteronomous process which gives rise to independence between causal processes and behaviours arising from forced submission. Pro-attitudinal requests (for blood-giving and homework aid) generate an autonomous process predisposing to commitment and attitude change in internals compared with externals. The intervention of causal explanatory models is cost-related : the more costly the pro-attitudinal request is, the more the internals differ from the externals in commitment and subsequent attitude change

Testo completoOur work proposes to analyze users' behavior using video data. Our objective is to contribute understanding how and why users view each video sequence. We present an approach combining intra-video and inter-video behavior analysis. The intra-video level represents the viewing of a video sequence. The inter-video level represents the sessions (linkage between videos viewed by users). An intra-video behavior is defined by a Markov model built using the actions performed during viewings. We cluster these behavior with a new method derived from K-Means adapted to the use of Models (K-Models). We then characteriz several typical behaviors that allows to estimate the level of interest of each video. An inter-video behavior is defined by a session. This session is an ordered sequence of viewings performed by the users. ln order to cluster these sessions, we propose a hierarchical technique, representing clusters by a set of common subsequences enriched by intra-video behaviors. Results from test sets allow to identify observed behaviors and to conclude on the interest of the videos. We also propose a framework on how to integrate our approach in a search engine in order to detect indexing errors and to propose altemate searches to the users

Testo completoEnsuring people’s safety in case of fire requires evacuating the building. In the current societal context, evacuation must be rethought. The objective is to propose two tools with which to anticipate crisis that could occur in people facing an emergency based on human behaviour and the evacuation process. The Accessibility law of 2005 highlighted that we will all be affected by it at one time or another. The presence of more or less toxic fumes, impeding obstacles, and confusing noises. . . Have a negative impact on our abilities and faculties and complicate the evacuation process. The approach is based on a study of the perception of risk by elderly persons and of persons with disabilities, so as to be able to transpose the experience to all, which, as it is agreed that the phase of awareness of danger is the most important in the evacuation process. Three different methods were used: a qualitative method of questionnaire analysis to understand the perception of risk, a systemic approach to understand the process of evacuation in its entirety and a cindynic approach to determine the sources of danger. The results lead to the characterisation of the structuring factors and bias engaged in risk perception, to creating a static and dynamic modelling of the evacuation process and to propose two crisis anticipation tools: Building evacuation engineering and Evacuation management

Testo completoThe human skeleton aims at participating to the locomotor system, protecting and serving as brackets for the internal organs. To ensure the mechanical stiffness of the entire body, the cortical bone can be found in every part of the skeleton. A dynamic process occurs throughout the life and is named bone remodelling. This process adapts the cortical bone architecture and the shape of bones according to their functions. Due to its complexity, bone remodelling can defect in the elderly and weakens bones. This thesis studies the bearing and non-bearing long human bones by focusing on the humerus and femur. A survey of the state of the art, detailed in the first chapter, reveals several lacks. First, the femur is widely investigated compared to the other bones and this unbalance creates a lack of data for the other bones. Therefore, inputs for numerical human models come from deprecated and contradictory studies where the extra-individual differences impact the trends. Second, architectural studies are mainly limited to in-plane assessment whereas the vascular network is complex and needs more robust analyses. Thus, the second chapter describes an innovative method to 3D assess the cortical vascular network from tomographic data. This Python script automatically detects canals, connectivity and Bone Multicellular Units (BMUs), cradle of the bone remodelling activity. Then, 77 samples from left and right femurs and humeri of ten human cadavers are scanned and analysed using this method. As this method provides numerous novel features of the cortical architecture, tensile and indentation tests are also carried out in order to understand and exhibit the impact of the architecture on the mechanical behaviour. Hence, all the scanned samples are tested and available for statistical analysis. So as to identify global trends, humerus and femur are compared using different statistical tests. Likewise, the bias impact is also investigated. Finally, a correlation study followed by a regression study is described so as to provide polynomial functions in order to be used to predict the mechanical behaviour from an architectural study
Cappe, Céline. "Intégration multisensorielle et motrice chez le primate non humain : approches anatomique, comportementale et électrophysiologique". Toulouse 3, 2007. http://www.theses.fr/2007TOU30066.
Testo completoIn order to interact with the multimodal world which surrounds us, we must integrate simultaneously various sources of sensory information (vision, hearing, body sensation…). A fundamental question is thus to know how the brain integrates the separate elements of an object defined by several sensory components to form a unified percept. The superior colliculus was the main model to study the polymodal integration. At the cortical level, until recently, polymodal integration appeared to be a characteristic that only had the associative areas located at the top of the information processing hierarchy. First of all, our first study related to cortico-cortical connections and showed the existence of direct projections between cortical areas of different sensorialities in the non human primate. Then, the study of projections between different sensory and motor cortical areas and the thalamus enabled us to highlight the existence of thalamic nuclei which, by their connections, could represent an alternative pathway for the information transfer of different sensory and/or motor cortical areas. The thalamus could allow a faster transfer and even an integration of information. In addition, at the behavioral level, multisensory integration allows an improvement of perception. .

Testo completoTo evaluate a human behavior is equivalent to evaluate all the markers translating this behavior (gestures, lyrics interactions, etc.). The observation by a human of certain markers such as facial expressions, prosody or linguistics, requires specialized training. To facilitate the assessment of behavior, scales indicating the observations to be made and the conclusions to be made are used. Thus, automating the evaluation of the behavior amounts to automate the analysis of an environment by means of several sensors, then analyzing the signals obtained in order to extract the markers allowing the deduction of the observed behavior. Due to the variability of human observations in overly specific analyzes, more and more studies are using thes automatic observation and behavioral evaluation systems. The objective is to assist human analysis and evaluation by exploiting automatic systems capable of extracting information that is difficult to observe for humans. As a result, the collaboration between the human and the computer systems makes it possible to analyze more elements of the behavior in a reliable and objective way. This thesis proposes an approach of behavior analysis based on the collaboration between humans and an automatic system. We set up an electronic and computer platform consisting of a mobile robot and an ambient system to evaluate human behavior. This platform is defined as: — Modular to the addition or removal of sensors: The addition and removal of sensors is feasible without a system is impacted otherwise than its performance to accurately recognize behaviors; — Accessible to Reading Recorded Data: The use of ontologies, as a semantic and logical database, makes the platform usable and accessible to people unfamiliar With complex computer systems; — Robust to ambiguities: every platform system (ambient or robot) is independent and has its own representation of the environment. However, they collaborate With each Other to respond to inconsistencies or lack of information during the performance of a task

Testo completoIndustrial robots have evolved fundamentally in recent years to reach the industrial requirements. We now find more suitable anthropomorphic robots leading to the realization of more complex tasks like deformable objects cutting such as meat cutting or constrained to high stresses as machining. The behavior study of anthropomorphic robots, parallel or hybrid one highlights a kinematic and dynamic anisotropy, which impacts the expected accuracy. This thesis studied the integration of the kinematic redundancy that can partially overcome this problem by well setting the task to achieve it in a space compatible with the expected capacity. This work followed a three-step approach: analytical modeling of robotic cells by serial equivalent based on the TCS method, formalizing the constraints of meat cutting process and machining process and a multicriteria optimization.The first originality of this work focuses on the development of a 6 DoFs model to analyze the operator actions who naturally optimizes his arm behavior to ensure the task it performs. The second originality concerns the optimized placement of structural redundancy (9 DoFs robotic cell) where positioning parameters are incorporated as controllable variables (11 DoFs robotic cell). Thus, the thesis makes contributions to : - the definition of criteria adapted to the realization of complex and under high stress task for the management of the kinematic redundancy; - the structural behavior identification, under stress, by metrology tools (Laser tracker ) and the self- adaptation paths by using an industrial force control; - the behavior optimization to improve the cutting process quality (meat cutting and machining)

Testo completoIndividuals do not always enact their intentions into behaviours, which may lead to severe outcomes especially in health-related fields. Self-regulation strategies, like cuedependent plans interventions, have shown efficiency to help to counter the intentionbehaviour gap. Yet, no review has been realised recently to bring a qualitative and quantitative analyses of this effect.Firstly, we carried out a qualitative review to evaluate the effectiveness of cuedependent planning intervention to increase health-related behaviours. We included 329 studies with experimental and prospective designs that measured or evaluated the effect of cue-dependent plans (e.g. implementation intention, action planning, coping planning) on health-related behaviours, among general, clinical and student population. The qualitative analysis revealed for instance that implementation intentions were used in majority, even if the if-then format was not systematically adopted. However, we oticed confusion between the terminologies of the plans and the theories. A quantitative review will be realised to evaluate the effect size and the moderators that could magnify or diminish the effects of cuedependent planning interventions on health-related behaviours. Second, we presented two studies that tested the effectiveness of cue-dependent planning interventions on physical activity, which was the most represented health outcome in cue-dependent planning interventions, according to our review. Motivational (mental simulation) and volitional (implementation intention) interventions were combined to promote physical activity participation. The first study, adopting a cluster randomised controlled trial design among students, did not show any significant effect neither of the mental simulation plus implementation intention intervention, nor of the implementation intention intervention compared to the control condition. The second study adopted a more rigorous methodology with a full-factorial randomised controlled design, with a larger sample and objective measures of physical activity (attendance to gym centre). Nevertheless, the study revealed no statistically significant main or interactive effects of the mental simulation and implementation intention conditions on physical activity outcomes. Findings were not in line with previous research that showed effects of cue-dependent plans to promote physical activity. This adds to the necessity of identifying the moderators of these interventions in health behaviours.Thirdly, cue-dependent planning interventions are needed in illness behaviours. In chronic disease, non-adherence to medication is a public health problem that can lead to negative health outcomes. Even if the patients want to take their treatment, they may, for instance, forget it and fail to enact the behaviour. We tested the ability of an intervention adopting implementation intention and coping planning to promote medication adherence. In a randomized controlled trial, outpatients with cardiovascular diseases were randomly allocated to either an implementation intention and coping planning condition, or to a noplanning control condition. Findings revealed no significant effect of the intervention on medication adherence. However, post hoc moderator analyses showed that the beliefs moderated the effect of the intervention, which was effective in patients with lower necessity beliefs compared to those with higher necessity beliefs. The design used in the study did not enable to test the direct an interactive effect on medication adherence, so it would be necessary to replicate these findings with a full factorial design among patients with cardiovascular diseases

Testo completoThe purpose of this work was to contribute to the explanation of achievement differences between social groups. Several studies have revealed that the reputations of intellectual inferiority that usually target stigmatized group members can alter their cognitive functioning (i. E. Stereotype threat hypothesis, Steele, 1997). Though research has repeatedly demonstrated that the performance of low status group members, (e. G. Blacks in the United states or women) can be disrupted by stereotypes alleging intellectual inferiority when they are made salient, very little id known about the process underlying this pehnomenon. We hypotesized that the suspicion of lower ability faced by low status group members in evalutive settings can lead them to focus on the self-evalutation implications of a potential low performance. This focalization in turns would generate sel-regulation demands that would disrupt performance on the main task. Our first study shows that evaluative situations affect stigmatized individuals' self-esteem and motivation. Moreover, when these individuals have the opportunity to affirm positive aspects of the self, their performance increases (studies 2, 3 and 4). In other words and in accordance with our hypothesis, stereotype threat appears to involve some self-regulation. However studies 5 and 6 did not allow us to determine if individuals's focus on negative self-knowledge iduces a self-regulation activity interfering with performance. Nevertheless, our work suggests that self-image devaluation generated by negative stereotypes applicability in testing situations is responsible for stereotype threat effects. Further research we review and discuss reveals that, when intellectual abilities are not perceived as fixed anymore, or when some low status individuals invalidate negative sterotypes of their group, members of these stigmatized groups perform better in evaluative situations

Testo completoFor decades, the assessment of less-lethal weapons (LLW) and bulletproof vests has generated major interest from law enforcement agencies around the world. Indeed, these presumed less-lethal or non-lethal weapons are required to cause only significant pain to an individual to ensure their neutralization. Bulletproof vests, in turn, must provide a certain level of protection to reduce the risk of trauma related to their dynamic deformation. The Center for Research, Expertise and Logistics Support (CREL) of the French Ministry of the Interior aims to develop a tool to predict thoracic injury risk during non-penetrating ballistic impacts. It would therefore be possible to evaluate the performance of LLW and bulletproof vests before their deployment in operations. More precisely, this method must only be based on the direct measurement of the dynamic process of deformation of a synthetic gel block subjected to a ballistic impact. To address that issue, the numerical approach is considered in this thesis by the use of the human thorax dummy HUByx as an intermediate tool for the determination of transfer functions between experimental metrics on a gel block and the risk of injury. The reproduction of real impact conditions on HUByx thus requires the characterization and modeling of less-lethal projectiles as well as projectiles of firearms and bulletproof vests. They rely on an inverse method identification procedure applied to the Taylor test for modeling LLW and on the analysis of blunt impacts on the gel block for projectiles/bulletproof vests. Work is then dedicated to the mechanical characterization and modeling of the synthetic gel under dynamic loadings. Finally, a statistical approach based on correlation analyses is introduced using both experimental measurements, numerical data as well as case reports from the literature. A thorax mapping associated with the risk of rib fractures is established and only depends on an experimental metric

Testo completoDuring the last 50 years, a number of studies have been carried out on human locomotion and individual load carriage. Although these studies provide a valued theoretical framework, they do not allow to understand the mechanisms implemented by individuals when they have to carry collectively an object. Our project deals with the collective aspect of load carriage and attempts to understand how a dyad of individuals moves when individuals have to carry an object together. First, we measured several locomotor parameters commonly studied in biomechanics (using a kinematic, mechanical and dynamic approach) on healthy individuals carrying a light load. We studied each individual within a dyad separately and then considered the system formed by the dyad and the load. We also performed experiments where we increased the complexity of the collective load carriage task by asking individuals to perform a second task in the same time or by changing the mass of the load. Finally, in order to find an application of our experimental protocol in rehabilitation studies, we performed a preliminary study on the collective transport achieved by two patients suffering from intellectual disability. The results of this thesis allow to construct a sound study protocol of collective load carriage. We show that two subjects carrying an object together walk as economically as when they are walking separately. Achieving a second distractive task at the same time leads to the deterioration of the pendular displacement of the center of mass of the system formed by the individuals and the load they carry. The displacement of this system is also impacted when the mass of the load carried is increased. For loads equal to 40% of the body mass, our results show a deterioration of the pendular behavior and a decrease of the amplitude of the center of mass of the system. Finally, for individuals suffering from an intellectual disability, we show that the collaboration between two pathological individuals is less interesting from a rehabilitation point of view than the collaboration with a healthy individual
Ben, Hadj Yahia Mohamed-Béchir. "Données et outils pour l'optimisation de l’impact de la vaccination prophylactique contre les papillomavirus humains en France". Thesis, Lille 2, 2015. http://www.theses.fr/2015LIL2S041/document.
Testo completoIntroduction: Since 2007, prophylactic vaccination against human papillomavirus (HPV) has been recommended in addition to cervical screening in French women. However, given the low vaccine coverage in France, the epidemiological impact of the vaccination is debated, as well as the choice of the target population and the means to ensure compliance with the recommendation. This doctoral thesis provides original data and tools for the evaluation and the improvement of the impact of HPV vaccination in France. For quantitative aspects, modelling HPV transmission based on the best data describing sexual partnerships in the general population is essential. The investigation of potential links between participation to cervical screening of deprived women and their choice of vaccinating their daughters, the appraisal of vaccine acceptability through social media and the cost-effectiveness evaluation of the relevance of extending the HPV vaccination program to include males are key elements to improve the focus on targeted populations.Methods: We developed a modelling platform to study the dynamics of HPV transmission, using data from Social Context of Sexuality, the latest national French sexual behavior study. Using finite mixture models, we identified latent classes of sexual activity to define profiles of partner acquisition with age, likely to have different risks of sexually transmitted infections. Then, we asked women attending the Centre for Preventive Medicine and Health Education of Lille, who had at least a daughter eligible for HPV vaccination, about their attitudes towards cervical screening and HPV vaccination. Next, we explored sentiments about HPV vaccine safety, efficacy and perceptions, spontaneously expressed by web users on the online discussion forum of a French-speaking health information website. Finally, we performed a systematic review of the cost-effectiveness studies about extending HPV vaccination to include males.Results: Simulations from the modelling platform reproduced HPV infection prevalence observed in France. Nevertheless, results were sensitive to assumptions about sexual behavior, with discrepancies between men and women. Five latent classes of sexual activity were identified in men and in women. The cluster describing the highest level of sexual behavior represents 3.3% in women and 4.8% in men. Besides, daughters’ vaccination profile did not differ with their mothers’ profile of participation to cervical screening. The main reason for not vaccinating their daughters reported by mothers was lack of information, especially for those non-compliant with cervical screening recommendations. Moreover, negative sentiments, reported by the health website forum, evolved from 28.6% of total opinions in 2006 to 42.2% in 2013. The arguments expressed by “anti-vaccine” postings involved most often vaccine safety and negative vaccine perceptions. Finally, cost-effectiveness analyses show that extending the HPV vaccination program to include males is rarely found to be a cost-effective strategy. Nevertheless, the targeted vaccination of men having sex with men seems to be the best strategy from ethical and cost-effectiveness points of view.Discussion: The modelling platform of sexual contacts represents the basis of the evaluation of HPV vaccination impact. The surveillance of online forums enables the monitoring of vaccine acceptability and hence the targeting of preventive messages. Improving the HPV vaccine coverage requires offering girls and young women an organized vaccination program. In the lack of a school-based vaccination program, Centres for Preventive Medicine and Health Education offer an interesting alternative

Testo completoL'étude des processus d'évaluation des produits manufacturés apporte des informations clés sur la manière dont le produit va être perçu puis jugé. Par une approche pluridisciplinaire à la confluence des sciences de l'ingénieur et des sciences cognitives, notre travail contribue à la compréhension des processus de la cognition visuelle et de formation d'impression par l'usage de l'oculométrie. Les comportements oculomoteurs mesurés en situation d'évaluation visuelle du produit automobile sont caractérisés et catégorisés par des méthodes statistiques empruntées au traitement des images, à la biologie, à l'agronomie ou la psychophysique. Les liens entre l'attention visuelle et l'intégration cognitive des informations visuelles pour l'évaluation sont ensuite étudiés. Plusieurs paradigmes expérimentaux sont conçus : évaluation monadique ou par paire, à durée d'exposition libre ou limitée, depuis des positions d'observations libres ou contraintes. Il s'avère que les processus qui guident l'orientation du regard lors de l'évaluation visuelle de produits photographiés, tels que les habitacles automobiles, sont nombreux et imbriqués de manière complexe tant spatialement que temporellement. Ce travail développe un ensemble de protocoles et de préconisations d'usage de l'oculométrie, ainsi qu'une démarche d'analyse de ces données en cascade, afin de mettre en évidence les zones d'intérêt, les effets des consignes et les contributions relatives des différents processus attentionnels.
