Big Data Analytics for Time-Critical Mobility Forecasting From Raw Data to Trajectory-Oriented Mobility Analytics in the Aviation and Maritime Domains( )

5 editions published in 2020 in English and held by 16 WorldCat member libraries worldwide

This book provides detailed descriptions of big data solutions for activity detection and forecasting of very large numbers of moving entities spread across large geographical areas. It presents state-of-the-art methods for processing, managing, detecting and predicting trajectories and important events related to moving entities, together with advanced visual analytics methods, over multiple heterogeneous, voluminous, fluctuating and noisy data streams from moving entities, correlating them with data from archived data sources expressing e.g. entities characteristics, geographical information, mobility patterns, mobility regulations and intentional data. The book is divided into six parts: Part I discusses the motivation and background of mobility forecasting supported by trajectory-oriented analytics, and includes specific problems and challenges in the aviation (air-traffic management) and the maritime domains. Part II focuses on big data quality assessment and processing, and presents novel technologies suitable for mobility analytics components. Next, Part III describes solutions toward processing and managing big spatio-temporal data, particularly enriching data streams and integrating streamed and archival data to provide coherent views of mobility, and storing of integrated mobility data in large distributed knowledge graphs for efficient query-answering. Part IV focuses on mobility analytics methods exploiting (online) processed, synopsized and enriched data streams as well as (offline) integrated, archived mobility data, and highlights future location and trajectory prediction methods, distinguishing between short-term and more challenging long-term predictions. Part V examines how methods addressing data management, data processing and mobility analytics are integrated in big data architectures with distinctive characteristics compared to other known big data paradigmatic architectures. Lastly, Part VI covers important ethical issues that research on m obility analytics should address. Providing novel approaches and methodologies related to mobility detection and forecasting needs based on big data exploration, processing, storage, and analysis, this book will appeal to computer scientists and stakeholders in various application domains

Approche spatiale pour la caractérisation du contexte d'exécution d'un système d'information ubiquitaire by Mathieu Petit( Book )

2 editions published in 2010 in French and held by 2 WorldCat member libraries worldwide

Technology driven developments in wireless information access, power consumption, or real-time localization bring nomadic computing into being and go hand in hand with software design innovation. This thesis qualifies emerging challenges raised by mobile and distributed computing uses and examines their impacts on system design. A literature review of existing mobile systems frameworks shed light on desirable design methodologies improvements. An enriched design methodology is depicted to encompass these improvements. Such framework integrates a description of several geographic-based execution contexts with the early stages of the design. Along with user tasks analysis, this contextual description allows designers to relate user needs to system capabilities. On a higher level, the proposed environment-centered context description provides an input to user categorization. Users sharing same context are likely to access similar information and processes. Together, they may recommend and classify the data they interact with. These recommendations, derived from the users' spatial and interactive behaviours, enable group-based data and interface adaptations to avoid information overload in a mobile context. The testbed of the thesis is twofold. From the environment and context descriptions to the sketching of the client interface, the conceptual framework is at first applied to the design of a regatta tracking service. Next, a campus visit aid illustrates the benefits of multi-user recommendations and adaptations

Atlas, une plate-forme pour la modélisation et la simulation de systèmes désagrégés by Cyril Ray( Book )

2 editions published in 2003 in French and held by 1 WorldCat member library worldwide

Cette thèse introduit une méthodologie composée d'une démarche de modélisation et d'un support informatique pour la simulation et l'analyse de systèmes complexes à larges flux de données désagrégées. La démarche de modélisation intègre une description hiérarchique de l'organisation interne d'un système complexe. La structure de graphe est utilisée pour traduire une décomposition structurelle du système et établir une abstraction qui lie le niveau de représentation conceptuel et le système distribué sous-jacent. La plate-forme Atlas est un support de simulation distribuée à événements discrets dirigée par le temps. Une des particularités de la plate-forme réside dans le concept de migration par groupe qui donne une solution adaptée pour la simulation de systèmes désagrégés. L'utilisation de cette démarche de modélisation et de sa plate-forme est illustrée par une application en transport qui modélise et simule les flux de personnes entre les différents halls d'un terminal d'aéroport

Détection contextuelle de cyberattaques par gestion de confiance à bord d'un navire by Benjamin Coste( )

1 edition published in 2018 in French and held by 1 WorldCat member library worldwide

Dans le domaine maritime, la maitrise de la navigation et de la conduite d'un navire sont deux aspects essentiels pour la bonne marche et la sécurité du navire, des personnels et la préservation de l'environnement maritime. Or, les navires modernes embarquent de plus en plus de technologies informatisées, connectées et automatisées pour gérer ces fonctions primordiales. Ces technologies (capteurs, actionneurs, automates, logiciels) qui constituent le système d'information (SI) d'un navire peuvent cependant être leurrées ou corrompues par un tiers, remettant ainsi en cause la confiance qui leur est accordée. Dans ce contexte, une nouvelle approche de détection des falsifications des informations fondée sur l'évaluation de la confiance dans les composants du SI est proposée. Du fait de leurcomplexité, les systèmes d'information des navires peuvent être considérés comme des ensembles de blocs fonctionnels inter-reliés qui produisent, traitent et reçoivent des informations. La confiance d'un bloc fonctionnel producteur d'information est évaluée au travers de sa capacité, divisée en deux composantes (compétence et sincérité), à rendre compte de la situation réelle du navire. Elle se propage ensuite, à l'instar de l'information, aux autres entités du système, quelle que soit leur complexité. Différents scénarios ont été expérimentés grâce à l'élaboration d'un simulateur. La variabilité de la confiance face à des altérations volontaires d'informations numériques permet de déduire la survenue d'une attaque ainsi que sa cible sous certaines conditions. Sans se restreindre aux systèmes navals, l'approche proposée permet de s'adapter à une grande variété de situations incluant le facteur humain. Les travaux de cette thèse ont été soutenus et co-financés par la région Bretagne ainsi que la Chaire de Cyber Défense des Systèmes Navals impliquant l'Ecole Navale, IMT Atlantique, NavalGroup et Thales

Une approche holistique combinant flux temps-réel et données archivées pour la gestion et le traitement d'objets mobiles : application au trafic maritime by Loïc Salmon( )

1 edition published in 2019 in French and held by 1 WorldCat member library worldwide

Over the past few years, the rapid prolifération of sensors and devices recording positioning information regularly produces very large volumes of heterogeneous data. This leads to many research challenges as the storage, distribution, management,Processing and analysis of the large mobility data generated still needs to be solved. Current works related to the manipulation of mobility data have been directed towards either mining archived historical data or continuous processing of incoming data streams.The aim of this research is to design a holistic System whose objective is to provide a combined processing of real time data streams and archived data positions. The proposed solution is real-time oriented, historical data and informations extracted from them allowing to enhance quality of the answers to queries. A event paradigm is discussed to facilitate the hybrid approach and to identify typical moving objects behaviors. Finally, a query concerning signal coverage of moving objects has been studied and applied to maritime data showing the relevance of a hybrid approach to deal with moving object data processing
