Full textTo save time and money while designing new products, industry needs tools to design, test and validate the product using virtual prototypes. These virtual prototypes must enable to test the product at all Product Lifecycle Management (PLM) stages. Many operations in product’s lifecycle involve human manipulation of product components (product assembly, disassembly or maintenance). Cue to the increasing integration of industrial products, these manipulations are performed in cluttered environment. Virtual Reality (VR) enables real operators to perform these operations with virtual prototypes. This research work introduces a novel path planning architecture allowing collaboration between a VR user and an automatic path planning system. This architecture is based on an original environment model including semantic, topological and geometric information. The automatic path planning process split in two phases. First, coarse planning uses semantic and topological information. This phase defines a topological path. Then, fine planning uses semantic and geometric information to define a geometrical trajectory within the topological path defined by the coarse planning. The collaboration between VR user and automatic path planner is made of two modes: on one hand, the user is guided along a pre-computed path through a haptic device, on the other hand, the user can go away from the proposed solution and doing it, he starts a re-planning process. Efficiency and ergonomics of both interaction modes is improved thanks to control sharing methods. First, the authority of the automatic system is modulated to provide the user with a sensitive guidance while he follows it and to free the user (weakened guidance) when he explores possible better ways. Second, when the user explores possible better ways, his intents are predicted (thanks to geometrical data associated to topological elements) and integrated in the re-planning process to guide the coarse planning. This thesis is divided in five chapters. The first one exposes the industrial context that motivated this work. Following a description of environment modeling tools, the second chapter introduces the multi-layer environment model proposed. The third chapter presents the path planning techniques from robotics research and details the two phases path planning process developed. The fourth introduce previous work on interactive path planning and control sharing techniques before to describe the interaction modes and control sharing techniques involved in our interactive path planner. Finally, last chapter introduces the experimentations performed with our path planner and analyses their results

Full textThis thesis focuses on the behavioral study of tourist activity using a generic and interactive analysis approach. The developed analytical process concerns the tourist trajectory in the city and museums as the study field. Experiments were conducted to collect movement data in the tourist city using GPS signals, thus enabling the acquisition of a movement trajectory. However, the study primarily focuses on reconstructing a visitor’s trajectory in museums using indoor positioning equipment, i.e., in a constrained environment. Then, a generic multi-aspect semantic enrichment model is developed to supplement an individual’s trajectory using multiple context data such as the names of neighborhoods the individual passed through in the city, museum rooms, weather outside, and indoor mobile application data. The enriched trajectories, called semantic trajectories, are then analyzed using formal concept analysis and the GALACTIC platform, which enables the analysis of complex and heterogeneous data structures as a hierarchy of subgroups of individuals sharing common behaviors. Finally, attention is paid to the "ReducedContextCompletion" algorithm that allows for interactive navigation in a lattice of concepts, allowing the data analyst to focus on the aspects of the data they wish to explore

Full textOver the last decade, we have seen a rise in popularity of mobile applications based on phone location. These applications collect mobility tracks which describe the movement of users overtime. In the DA3T regional project, we hypothesise that the analysis of tourists’ mobility tracks can help planners in the management and enhancement of tourist areas. The objective is to design methods and tools to help analyse these tracks. This thesis focuses on the processing of mobility tracks and proposes a modular platform for creating and executing processing chains on these data. Throughout the modules of a processing chain, the raw mobility track evolves into semantic trajectories. The contributions of this thesis are: (i) a multi-level and multi-aspect semantic trajectory model and (ii) two measures that compute the similarity between two semantic trajectories along spatial, temporal and thematic dimensions. Our model (i) is used as a transition model between modules of a processing chain. We tested it by instantiating semantic trajectories from different datasets of various domains. Our two measures (ii) are integrated in our platform as processing modules. These measures present originalities: one is the combination of sub-measures, each allowing to evaluate the similarity of trajectories on the three dimensions and according to three different levels of granularity, the other is the combination of two bidimensional sub-measures centred around a particular dimension. We evaluated our two measures by comparing them to other measures and to the opinion of geographers

Full textMassive trajectory datasets generated in modern cities generate not only novel research opportunities but also important methodological challenges for academics and decision-makers searching for a better understanding of travel patterns in space and time. This PhD research is oriented towards the conceptual and GIS-based modeling of human displacements derived from large sets of urban trajectories. The motivation behind this study originates from the necessity to search for and explore travel patterns that emerge from citizens acting in the city. Our research introduces a conceptual modelling framework whose objective is to integrate and analyze human displacements within a GIS-based practical solution. The framework combines conceptual and logical models that represent travel trajectories of citizens moving in a given city. The whole approach has been implemented in a geographical database system, experimented in the context of transportation data, and enriched by a series of query interface manipulations and specific functions that illustrate the potential of our whole framework for urban studies. The whole framework has been experimented on top of the Geolife project and large trajectories datasets available in the city of Beijing. Overall, the findings are twofold: first, it appears that our modelling framework can appropriately act as an extensible geographical database support for the integration of large trajectory datasets; second the approach shows that several emerging human displacements can be explored from the manipulation of large urban trajectories

Full textThis thesis focuses on the characterization and recognition of human activities in videos. This research domain is motivated by a large set of applications such as automatic video indexing, video monitoring or elderly assistance. In the first part of our work, we develop an approach based on the optical flow estimation in video to recognize human elementary actions. From the obtained vector field, we extract critical points and trajectories estimated at different spatio-temporal scales. The late fusion of local characteristics such as motion orientation and shape around critical points, combined with the frequency description of trajectories allow us to obtain one of the best recognition rate among state of art methods. In a second part, we develop a method for recognizing complex human activities by considering them as temporal sequences of elementary actions. In a first step, elementary action probabilities over time is calculated in a video sequence with our first approach. Vectors of action probabilities lie in a statistical manifold called semantic simplex. Activities are then represented as trajectories on this manifold. Finally, a new descriptor is introduced to discriminate between activities from the shape of their associated trajectories. This descriptor takes into account the induced geometry of the simplex manifold

Full textThe notion of trajectory is the subject of many works in computer science. The life trajectory has several peculiarities which distinguish it from the trajectories usually considered in these works. It is first of all its temporal hold, which is the life, the existence of the observed subject. It is then its thematic hold, this one potentially concerning multiple aspects of the life of an object or an individual. Finally, it is the metaphorical use of the term trajectory, which refers more to the meaning of the trajectory than to the description of a simple evolution in time and space. The life trajectory is used by the expert (sociologist, urban planner ...) who wishes to put in perspective the information on individuals to better understand their choices. The motivations for studying the life trajectory are depending on the application and themes considered: the relation to work and employment, family life, social life, health, residential trajectory ...We propose a Semantic Web based approach to study life trajectories, which allows their modeling, collection and analysis. This approach is embodied by a software architecture whose components are configurable for each application case. This architecture is based on a life trajectory ontology design pattern, as well as a model of explanatory factors for life events. To operationalize the proposed modeling, we designed algorithms that allow the creation of a life trajectory ontology by exploiting the previous pattern and model. For data collection, we developed APIs to facilitate i) the construction of a model-compliant data collection interface; and ii) the insertion of the collected data into a Triple Store. Our approach allows the representation, and hence the collection and exploitation of multi-granular information, whether spatial, temporal or thematic. Finally, to allow the analysis of the trajectories, we propose generic functions, which are implemented by extending the SPARQL language.The methodological approach and the proposed tools are validated on a case study on residential choices of individuals in the Grenoble metropolitan area by highlighting the characteristics of their residential trajectory and the explanatory elements of it, including from their personal and professional trajectories

Full textSignaling pathways describe the extern stimuli responses of a cell. They are indispensable in biological processes such as differentiation, proliferation or apoptosis. The Systems Biology tries to study exhaustively the signalling pathways using static or dynamic models. The number of solutions which explain a biological phenomenon (for example the stimulus reaction of cell) can be very high in large models. First, this thesis proposes some different strategies to group the solutions describing the stimulus signalling with clustering methods and Formal Concept Analysis. Then, it presents the cluster characterization with semantic web methods. Those strategies have been applied to the TGF-beta signaling network, an extracellular stimulus playing an important role in the cancer growing, which helped to identify 5 large groups of trajectories characterized by different biological processes. Next, this thesis confronts the problem of heterogeneous data translation from different bases to a unique formalism. The goal is to be able to generalize the previous study. It proposes a strategy to group signaling pathways of a database to an unique model, then to calculate every signaling trajectory of the stimulus

Full textReusing healthcare administrative databases for public health research is relevant and opens new perspectives. In pharmacoepidemiology, it allows to study large scale diseases as well as care consumption for a population. Nevertheless, reusing these information systems that were initially designed for accounting purposes and whose interoperability is limited raises new challenges in terms of representation, integration, exploration and analysis. This thesis deals with the joint use of healthcare administrative databases and biomedical knowledge for the study of patient care trajectories. This includes both (1) exploration and identification through queries of relevant care pathways in voluminous flows, and (2) analysis of retained trajectories. Semantic Web technologies and biomedical ontologies from the Linked Data allowed to identify care trajectories containing a drug interaction or a potential contraindication between a prescribed drug and the patient’s state of health. In addition, we have developed the R queryMed package to enable public health researchers to carry out such studies by overcoming the difficulties of using Semantic Web technologies and ontologies. After identifying potentially interesting trajectories, knowledge from biomedical nomenclatures and ontologies has also enriched existing methods of analysing care trajectories to better take into account the complexity of data. This resulted notably in the integration of semantic similarities between medical concepts. Semantic Web technologies have also been used to explore obtained results

Full textLocation data is ubiquitous in many aspects of our lives. We are witnessing an increasing usage of this kind of data by a variety of applications. As a consequence, information systems are required to deal with large datasets containing raw data in order to build high level abstractions. Semantic Web technologies offers powerful representation tools for pervasive applications. The convergence of location-based services and Semantic Web standards allows an easier interlinking and annotation of trajectories.In this thesis, we focus in modeling mobile object trajectories in the context of the Semantic Web. First, we propose an ontology that allows the representation of generic episodes. Our model also handles contextual elements that may be related to trajectories. Second, we propose a framework containing three algorithms for automatic annotation of trajectories. The first one detects moves, stops, and noisy data; the second one is able to compress generic time series and create episodes that resumes the evolution of trajectory characteristics; the third one exploits the linked data cloud to annotate trajectories with geographic elements that intersects it with data from OpenStreetMap.As results of this thesis, we have a new ontology that can represent spatiotemporal phenomena at different levels of granularity. Moreover, our framework offers three novel algorithms for trajectory annotation. The move-stop-noise detection method is able to deal with irregularly sampled traces and do not depend on external data of the underlying geography; our time series compression method is able to find values that summarize a series at the same time that too small segments are avoided; and our spatial annotation algorithm explores linked data and the relationships among concepts to find relevant types of spatial features to describe the environment where the trajectory took place
