La rééducation myofonctionnelle orofaciale (RMOF) a été montrée efficace dans le traitement multidisciplinaire des syndromes d’apnées obstructives du sommeil (SAOS) de l’enfant, de l’adolescent et de l’adulte et elle est prescrite à plusieurs étapes de ces prises en charge. La santé connectée fait appel à l’utilisation de messages électroniques, à une surveillance à distance, à des plateformes de télémédecine du sommeil et à des applications de santé mobile. Les objets connectés aident au diagnostic du SAOS, ils permettent la télésurveillance des patients traités par pression positive continue et facilitent la prise en charge des comorbidités liées au SAOS. La première application conçue pour réaliser une RMOF chez des patients souffrant de SAOS, nommée Airway Gym®, a été conçue par O’Connor-Reina et al. en 2017. Elle permet au patient d’interagir directement avec le smartphone sans avoir besoin d’un autre appareil et elle vise à améliorer la tonicité des différents muscles impliqués dans la pathogenèse du SAOS. Un essai clinique randomisé a évalué les effets de l’application Airway Gym® chez des patients atteints de SAOS sévère, et montré des améliorations significatives de l’IAH, du score de l’échelle de somnolence d’Epworth, de la saturation minimale en O2, du score maximal de la langue IOPI et du score maximal des lèvres IOPI.

Les messages vocaux de WhatsApp n’ont pas les mêmes modalités d’utilisation que les messages écrits de cette application. Dès lors ce travail s’interroge sur les traits distinctifs des messages vocaux et tente de définir s’ils correspondent à un nouveau genre ou à une évolution d’un genre digital préexistant. Pour ce faire, six conversations WhatsApp ont été transcrites et examinées. L’analyse de ces messages met au jour les constantes suivantes : une exacerbation de l’aspect phatique des messages, un sentiment de présence connectée et une place importante accordée à la méta-réflexivité. Ces caractéristiques sont visiblement liées au fait que la communication médiée par les messages vocaux WhatsApp représente un genre hybride entre l’oral et l’écrit.

The data science of networks is a rapidly developing field with myriad applications. In neuroscience, the brain is commonly modeled as a connectome, a network of nodes connected by edges. While there have been thousands of papers on connectomics, the statistics of networks remains limited and poorly understood. Here, we provide an overview from the perspective of statistical network science of the kinds of models, assumptions, problems, and applications that are theoretically and empirically justified for analysis of connectome data. We hope this review spurs further development and application of statistically grounded methods in connectomics.

Full textAbstract:
Connected vehicle (CV) application developers need a development platform to build, test, and debug real-world CV applications, such as safety, mobility, and environmental applications, in edge-centric cyber-physical system (CPS). The objective of this paper is to develop and evaluate a scalable and secure CV application development platform (CVDeP) that enables application developers to build, test, and debug CV applications in real-time while meeting the functional requirements of any CV applications. The efficacy of the CVDeP was evaluated using two types of CV applications (one safety and one mobility application) and they were validated through field experiments at the South Carolina Connected Vehicle Testbed (SC-CVT). The analyses show that the CVDeP satisfies the functional requirements in relation to latency and throughput of the selected CV applications while maintaining the scalability and security of the platform and applications.

Full textAbstract:
To build on a project recently completed for the Oregon Department of Transportation (DOT), processes and tools were developed to prioritize the implementation of connected vehicle (CV) applications. Internal mechanisms for addressing CV development and deployment at the Oregon DOT were assessed; the technical maturity of each potential CV application was scanned, reviewed, and assessed; preliminary goals were developed; prospective CV applications were linked; and applications that fit with the potential role of the Oregon DOT in advancing these initiatives were refined, prioritized, and ranked. A shared vision and business plan that prioritizes CV applications for Oregon is recommended. An internal effort aimed at producing a small set of priority CV applications for further development is described. This effort culminated in a CV application prioritization workshop that included a priority mapping exercise, discussion of the CV concept, and an initial mapping of goals and applications. The workshop identified seven near-term priority CV applications for the Oregon DOT; 12 applications that the Oregon DOT will monitor (and possibly collaborate on with others in the future); and eight applications that the Oregon DOT will monitor but that will be led by others. The Oregon DOT has used the results of this effort as a springboard for hiring new staff dedicated to CV policy, forming a CV steering team, and launching a CV business plan. The process and tools can be used by other states and transportation agencies in their CV application prioritization processes.

Face à nombreux défis, les organisations compétitives de nos jours sont celles qui transforment rapidement les nouvelles idées en nouveaux produits ou services. C'est pourquoi, elles cherchent à mieux maîtriser leur processus d'innovation et à le rendre plus efficace sur l'ensemble des fonctions de leur chaîne de valeur, depuis la phase de génération des idées jusqu'à leur mise sur le marché. De plus, au cours des quinze dernières années, les grandes entreprises ont ouvert leurs processus d'innovation en raison de la nécessité de cycles d'innovation de plus en plus courts et de délais de commercialisation réduits. Cependant, nous constatons qu'il n'y a pratiquement aucune approche formelle dans la littérature liée à la modélisation de l'innovation qui rationalise la gestion du processus d'innovation dite "ouverte". Dans ce contexte, nous développons un cadre méthodologique en ciblant in fine le processus de l'innovation ouverte afin de le formaliser et rationaliser sa gestion. La démarche de l'ingénierie dirigée par les modèles mise en place nous permet de proposer une approche formelle pour bien structurer la gestion de l'innovation ouverte. Pour cela, notre recherche s'est focalisée dans un premier temps sur la conception d'un modèle conceptuel qui décrit les connaissances inscrites dans le périmètre du management de l'innovation ouverte grâce à une formalisation en UML. Ce modèle conceptuel est considéré comme le socle de référence de notre cadre méthodologique puisqu'il est générique et peut être appliqué à toute innovation. Nous avons ensuite proposé un modèle de cycle de vie qui décrit le processus de l'innovation ouverte, fondé sur la collaboration et l'échange entre les différents acteurs. Nous avons détaillé ce modèle en processus métiers collaboratifs à l'aide des diagrammes BPMN pour décrire les activités opérationnelles, et des diagrammes DMN pour cadrer les activités de prise de décisions. Enfin, nous avons illustré ce cadre méthodologique sur deux cas d'études liés au domaine de la santé connectée, afin de tester sa validitéFaced with many challenges, competitive organizations today are those that quickly transform new ideas into new products or services. This is why they are seeking to better control their innovation process and make it more efficient across all functions of their value chain, from the idea generation phase to their launch. In addition, over the past 15 years, large companies have opened up their innovation processes due to the need for shorter innovation cycles and shorter time to market. However, we note that there is virtually no formal approach in the literature related to innovation modeling that streamlines the management of the so-called "open" innovation process. In this context, we are developing a methodological framework by targeting the open innovation process in order to formalize it and rationalize its management. The Model-Driven Engineering approach implemented allows us to propose a formal approach to properly structure the management of open innovation. To this end, our research focused initially on the design of a conceptual model that describes the knowledge included in the scope of open innovation management through formalization in UML. This conceptual model is considered the reference base of our methodological framework since it is generic and can be applied to any type of innovation. Then, we proposed a life cycle model that describes the process of open innovation, based on collaboration and exchange between the different actors. We have detailed this model into collaborative business processes using BPMN diagrams to describe operational activities, and DMN diagrams to frame decision making activities. Finally, we illustrated this methodological framework on two case studies related to the field of connected health, in order to test its validity

Full textAbstract:
Dans le contexte de l’Internet des Objets, la conception de services connectés – c’est-à-dire de services portés par des objets connectés – nécessite une approche de bout en bout pour non seulement répondre aux attentes des bénéficiaires de ces services mais aussi pour adapter le fonctionnement de ces services à des conditions d’exécution très variées allant de la maison à la ville connectée. L’approche sémantique proposée par cette thèse offre un niveau d’abstraction qui permet aux concepteurs de services de se concentrer sur les aspects fonctionnels des services et des objets. Elle s’inscrit dans un cadre d’architecture plus large qui aborde, en plus de ce niveau sémantique, les aspects plus opérationnels de mise en oeuvre de ces services (niveau Artefacts) dans des environnements techniques éventuellement hétérogènes (niveau Ressources). En proposant cette approche sémantique de conception, la thèse vise plusieurs objectifs qui peuvent être regroupés en trois catégories. La première catégorie d’objectifs est de décloisonner le monde actuel des services connectés en découplant les services des objets connectés et en permettant le partage d’objets par plusieurs services connectés. L’ouverture induite par ces premiers objectifs conduit à viser une deuxième catégorie d’objectifs qui a trait à la composition des services connectés. Chaque service devra être conscient et adopter un comportement compatible avec les autres éléments de son contexte d’exécution. Ces éléments de contexte comprennent bien sûr les autres services mais aussi les phénomènes physiques et les actions des occupants des espaces concernés. Enfin, la troisième catégorie d’objectifs s’adresse plus s’adresse plus particulièrement aux bénéficiaires des services connectés afin d’optimiser l’expérience utilisateur par des attentes mieux prises en compte et des automatismes respectueux des comportements humains. Le fondement théorique de l’approche sémantique proposée dans cette thèse s’appuie sur un méta-modèle qui permet de définir les éléments de modélisation nécessaires pour modéliser les services, les objets connectés et les comportements des services sous forme déclarativeIn the context of the Internet of Things, the design of connected services - that is, services supported by connected objects - requires an end-to-end approach to not only meet the expectations of the recipients of these services but also to adapt the operation of these services to a wide range of execution conditions spreading from smart homes to smart cities. The semantic approach proposed in this thesis provides a level of abstraction that allows service designers to focus on the functional aspects of services and objects. It is part of a larger architecture framework that addresses, in addition to this semantic level, the more operational aspects of implementation of these services (Artifacts level) in potentially heterogeneous technical environments (Resources level). By proposing this semantic design approach, the thesis aims at achieving several objectives that can be grouped into three categories. The first category of objectives is to decompartmentalize the current world of connected services by decoupling services from connected objects and allowing the sharing of objects by several connected services. The openness induced by these first objectives leads to a second category of objectives that relates to the composition of connected services. Each service will have to be aware and adopt a behavior compatible with the other elements of its execution context. These contextual elements include of course the other services but also the physical phenomena and the actions of the occupants of the spaces concerned. Finally, the third category of objectives focusses on at the recipients of connected services in order to optimize the user experience through better requirement management and automatisms respectful of human behaviors. The theoretical basis of the semantic approach proposed in this thesis is a meta-model that defines the modeling elements needed to model services, connected objects and service behaviors in a declarative form

Full textAbstract:
Contexte : La carence en fer est fortement prévalente en population générale, notamment chez les femmes réglées. La carence en fer peut entraîner l'apparition d'une anémie, altère la qualité de vie et les performances cognitives et est responsable d'une augmentation de la morbidité pendant la grossesse. La pâleur muqueuse, bien visible au niveau conjonctival et la coloration bleutée de la sclère sont des signes cliniques classiques mais subjectifs d'anémie et de carence en fer. Le diagnostic de certitude est coûteux, eu égard à la prévalence de la pathologie et repose sur la réalisation d'un hémogramme et d'un dosage de ferritine sérique. Notre objectif est de mettre au point un dispositif non invasif de dépistage de l'anémie et de la carence en fer par analyse en image artificielle d'images de l'œil.Patientes et méthodes : nous avons construit un modèle d'apprentissage profond pour la prédiction de l'anémie (hémoglobine < 12 g/dL) et de la carence en fer (ferritine < 20 µg/L) à partir de photographies de l'œil (sclère et conjonctive palpébrale inférieure). Les images étaient réalisées de façon standardisées avec un smartphone et une caméra professionnelle d'ophtalmologie (Lacrydiag®). Pour chaque sujet, 4 images avec la sclère et 2 images avec la sclère et la conjonctive (par traction douce sur la paupière inférieure) étaient réalisées par œil selon chacune des méthodes (smartphone et caméra Lacrydiag). Nous avons recruté prospectivement des patientes adultes ayant bénéficié d'un dépistage de l'anémie ferriprive (hémogramme et ferritine). Les pathologies hémolytiques, les antécédents de pathologies héréditaires du tissu conjonctif, ou toute intervention ou traumatisme susceptibles de modifier l'aspect de l'œil étaient des critères d'exclusion.Résultats : Nous avons inclus 202 femme (âge médian 22 ans, hémoglobine médiane 13 g/dL), dont 49.5% étaient carencées en fer (ferritine médiane 11 µg/L, Q1-Q3 : 7-14) et 17% étaient anémiques (hémoglobine médiane 11.4 g/dL, Q1-Q3 : 10.8-11.7). Après reconstruction en « High Dynamic Range » des images smartphone, une segmentation automatisée des photographies fournissait des masques d'images comprenant uniquement les zones d'intérêt (sclère, conjonctive). Ces masques était soumis à un panel de réseaux neuronaux convolutionnels (plateforme Autokeras, Université du Texas), permettant de trouver le meilleur modèle prédictif. Une tendance non significative (p = 0.06) entre les valeurs de ferritine prédites et réelles était identifié sur l'algorithme en régression sur les images HDR du smartphone. Aucune corrélation n'était identifiée en régression pour l'hémoglobine quel que soit le type d'image, ni pour la ferritine sur les images Lacrydiag. En classification, les meilleurs résultats pour la classification de la carence en fer étaient obtenus avec un seuil de ferritine < 15 µg/L sur les images HDR de la sclère, avec une sensibilité de 59%, une spécificité de 75.6% et une valeur prédictive négative de 75%. Pour la classification de l'anémie, l'algorithme sur les images HDR de la conjonctive donnait une sensibilité de 66.7%, une spécificité de 77.6%, une valeur prédictive positive de 38.1% et une valeur prédictive négative de 91.8%.Conclusion : les performances de l'algorithme pour la prédiction de l'anémie à partir d'images smartphone de la conjonctive et de la sclère sont encourageantes. En régression, les résultats sont non significatifs mais une tendance est notée pour la prédiction de la ferritine sur les images HDR. Pour le dépistage de la carence en fer, l'algorithme de classification offre une sensibilité moyenne. Afin d'améliorer les performances de cet outil de dépistage, il est indispensable d'augmenter les effectifs de la base d'apprentissage, et de la valider dans d'autres populations hommes, patients âgés comorbides)Background: Iron deficiency is highly prevalent in the general population, particularly in women of childbearing age. Iron deficiency increases pregnancy morbidity, impairs the quality of life through decrease of cognitive performance and can lead to anemia. Mucosal pallor, easily identified on the palpebral conjunctiva is widely used to predict anemia. Iron deficiency may also induce a bluish discoloration of the sclera, but these signs are subjective. However, certainty diagnosis lays on full blood count and serum ferritin dosage, representing a huge economic burden given to the prevalence of iron deficiency anemia. We aimed to build an affordable effective non-invasive diagnostic test through deep-learning eye image analysis to predict iron deficiency and anemia.Patients and methods: We built a deep-learning algorithm to detect anemia (hemoglobin < 12 g/dL) and iron deficiency (ferritin < 20 µg/L) through eye image analysis. For each subject, four images with the sclera and two images with the sclera and conjunctiva (by gentle traction on the lower eyelid) were taken per eye using a smartphone and a professional camera (Lacrydiag®) in similar lighting conditions. We prospectively included healthy adult women screened for iron deficiency anemia during routine medical practice. Hemolytic disease, connective tissue disease, eye surgery or trauma were exclusion criteria.Results: Among the 202 women recruited (median age 22 years, median hemoglobin 13 g/dL), 49.5% had iron deficiency (median ferritin 11 µg/L, Q1-Q3: 7-17) and 17 were anemic (median hemoglobin 11.4 g/dL, Q1-Q3: 10.8-11.7). Smartphone images were merged into High dynamic range format: mask of the sclera and conjunctiva (automated segmentation) were analyzed with a panel of convolutional neural network provided by Autokeras platform (Texas University) to identify the most efficient model. No significant correlation was found in regression analysis between real and predicted hemoglobin values with smartphone and Lacrydiag® images. Sensitivity and specificity for the prediction of iron deficiency (classification algorithm, ferritin < 15 µg/L) were 59% and 75.6% respectively with smartphone sclera images analysis (positive predictive value 59.8%, negative predictive value 75%). Sensitivity and specificity for the prediction of anemia (classification algorithm, hemoglobin < 12 g/dL) were 66.7% and 77.6% respectively with conjunctiva smartphone images analysis (positive predictive value 38.1%, negative predictive value 91.8%).Conclusion: the convolutional neural network analysis of the sclera and conjunctiva smartphone HDR image analysis is efficient to predict anemia. The model failed to predict hemoglobin level. Results for the ferritin prediction on HDR image analysis are encouraging but further analysis are still required. For iron deficiency screening, the classification model provided a modest sensitivity. To improve the performance of our model, it appears essential to increase the size of the learning database and to validate its efficacy in other populations (men, elderly comorbid patients)

Full textAbstract:
Cette thèse porte sur l’hybridation des dimensions virtuelle et corporelle de la mobilité. Elle interroge les effets de la mise en connexion de la mobilité quotidienne, et en particulier de la mobilité pendulaire, sous la double impulsion de la diffusion du smartphone et de l’amélioration de la qualité de la connexion aux réseaux de télécommunication dans les transports en commun. La mobilité, que nous décrivons comme connectée, permet à la fois le déploiement d’activités numériques au cours du déplacement, et l’accès facilité à une information personnalisée sur les conditions d’un déplacement projeté ou en cours via les applications d’aide à la mobilité sur smartphone. La problématique générale de ce travail de recherche peut être comprise à travers l’interrogation suivante : comment les usagers des transports en commun se saisissent-ils de la mise en connexion de la mobilité pour agir sur les contraintes spatio-temporelles du quotidien ? Trois hypothèses structurent cette recherche. La première hypothèse est celle d’un effet positif de la mise en connexion de la mobilité sur la valorisation du temps de déplacement. La deuxième hypothèse est celle de la recomposition, à l’heure de la mobilité connectée, de la spécificité de l’espace-temps du déplacement au regard des activités qui y sont déployées. La troisième hypothèse est celle d’une meilleure maîtrise de la mobilité résultant de l’ancrage dans les habitudes du recours à l’information personnalisée au moyen d’applications d’aide à la mobilité. À partir d’une enquête par entretiens semi-directifs réalisée entre 2013 et 2014 et d’une enquête par la passation de questionnaires en ligne en 2015, nous avançons, en réponse à ces trois hypothèses, l’idée que la mise en connexion de la mobilité soutient une banalisation du déplacement. À défaut de produire une valorisation du temps de déplacement, le smartphone atténue, pour l’individu, les effets négatifs des variations des conditions de trajets sur le niveau de confort du déplacement. De plus, du point la mise en connexion de la mobilité rend plus perméable cet espace-temps au déploiement d’activités structurant par ailleurs le quotidien. Enfin, les applications d’aide à la mobilité offrent, outre des voies d’optimisation temporelle des déplacements quotidiens, une forme de sécurisation de la mobilitéThis thesis focuses on hybridity between virtual and corporeal mobility. We study the effects of growing connectivity on daily mobility, and especially on commuting. ‘Connected’ mobility is characterised by the large-scale diffusion of smartphones and the improvement of broadband connection in public transportation. ‘Connected’ mobility allows travellers to use a wider range of on-trip activities and to receive personalised information about their current or future trips. The main issue is to determine how public transportation users use ‘connected’ mobility to their advantage to soften daily time-space constraints. Three hypotheses led this research. The first is the hypothesis of the valorisation of travel time through the use of ICT devices such as smartphones. The second is about the reshaping of mobility time-space through connectivity, regarding the activities practised by travellers in their daily lives. The third concerns the better control of daily mobility allowed by the use of mobile apps that provide personalised information. The study is based on two surveys. The first occurred during the years 2013 and 2014. It is composed of in-depth semi-directive interviews. The second is a large-scale survey led by on-line questionnaires in 2015. The main results support the idea that the growing connectivity of mobility underlines a banalisation of mobility. The use of smartphones does not clearly imply a greater valorisation of travel time, but softens the negative effects on travel comfort due to the variations of travel conditions. Moreover, the growing connectivity of mobility time-space allows the travellers to import in this specific time-space their daily activities. Finally, the mobile apps providing personalised information about mobility authorise travel optimisation but also secure the daily trips, improving the feeling of control on mobility

Bardot, Sandra. "Conception et évaluation de techniques d'interaction non-visuelle basées sur un dispositif personnel : application à l'exploration de cartes numériques par des personnes avec déficience visuelle." Thesis, Toulouse 3, 2019. http://www.theses.fr/2019TOU30061.
Full textAbstract:
Pour les personnes déficientes visuelles, les documents en relief sont importants pour l'accès à la connaissance. Afin de répondre aux spécificités de la perception haptique, il est nécessaire de simplifier la quantité d'information disponible au sein d'un document en relief. Ce processus s'appelle l'adaptation du contenu et repose sur l'intervention d'un spécialiste qui sait concevoir un contenu adapté à l'exploration tactile et à la compétence des utilisateurs. Comme la modification est impossible, celui-ci doit être refait à chaque changement. Ainsi, la possibilité d'utiliser et d'explorer un contenu numérique plutôt que physique représente une alternative intéressante. Un grand nombre de données numériques en accès libre est disponible, et l'adaptation des données peut être réalisée grâce à des algorithmes prévus à cet effet. Cependant, les documents numériques sont par essence visuels, et par conséquent inaccessibles aux personnes déficientes visuelles en l'état. L'état de l'art concernant l'exploration haptique de données numériques fait apparaitre un ensemble de solutions reposant sur un artefact (comme une souris à retour de force). Cette approche présente de nombreuses limitations, notamment le fait de parcourir le document avec un seul point de contact. Une approche plus fonctionnelle consiste à laisser l'utilisateur explorer un graphique numérique avec ses mains : chaque doigt peut alors être considéré comme un curseur. Les feedback sonore et vibratoire sont déclenchés en fonction de la position du doigt sur le document numérique. Cependant, il est nécessaire de connaitre les éléments importants d'un graphique (c'est-à-dire les éléments qui déclencheront des feedbacks), ainsi que le rôle de chacun des doigts au cours de l'exploration. La problématique de cette thèse porte sur l'exploration des données spatiales numériques en reposant sur des interactions haptiques. L'objectif est double : 1) comprendre comment les personnes déficientes visuelles explorent les graphiques en relief ; et 2) proposer des techniques d'interaction haptique, basées sur des dispositifs personnels et transportables, qui permettent aux utilisateurs déficients visuels d'explorer des graphiques numériques dans différents contextes (à la maison ou à l'école par exemple). Pour répondre au premier point, nous avons réalisé deux études portant sur les stratégies d'exploration des documents en relief, en fonction du niveau d'expertise des utilisateurs. Nous avons montré que les stratégies utilisées dépendent de l'expertise mais aussi du type de document exploré. Pour répondre au deuxième point, nous avons proposé de nouvelles techniques d'interaction reposant sur l'utilisation d'une montre connectée qui permet des feedbacks localisés. Nous avons mené deux études expérimentales concernant la conception et l'évaluation de techniques d'interaction haptiques basées sur la montre. La première étude portait sur la comparaison de l'exploration de graphiques physiques (en relief) à celle de graphiques numériques virtuels. Les résultats montrent que deux de nos techniques d'interaction permettent une exploration de graphiques numériques plus rapide que l'exploration de graphiques en relief. Notre deuxième étude visait à développer et évaluer des techniques d'interaction permettant l'utilisation des deux mains lors de l'exploration de contenus numériques. Les résultats montrent que les stratégies bimanuelles reposant sur un feedback bilatéral localisé améliorent les performances d'exploration de graphiques numériques. Les résultats de ces études mettent en avant les avantages d'une interaction haptique bimanuelle. Combinées à un dispositif de localisation et de suivi des mains, les techniques d'interaction développées sur une montre connectée pourraient permettre aux utilisateurs d'interagir avec des contenus numériques dans de nombreuses situations de la vie quotidienneFor visually impaired people, raised-line documents are important for access to knowledge. In order to respond to the specificities of haptic perception, it is necessary to simplify the amount of information available within a raised-line document. This process is called the adaptation of the content and relies on the intervention of a specialist who knows how to design content adapted to tactile exploration. As the modification is impossible, it must be printed again at each changes. Thus, the ability to use and explore digital rather than physical content is an interesting alternative. A large number of free access numerical data is available, and the adaptation of the data can be carried out by means of algorithms provided for this purpose. However, digital documents are essentially visual, and therefore inaccessible to visually impaired people as they are. The state of the art regarding haptic exploration of digital data reveals a set of solutions based on an devices (like a force feedback mouse). This approach has many limitations, including browsing the document with a single point of contact. A more functional approach is to let the user explore a digital graph with his hands: each finger can then be considered as a cursor. Feedback audio and vibration are triggered depending on the position of the finger on the digital document. However, it is necessary to know the important elements of a graph (the elements that will trigger feedback), as well as the role of each finger during the exploration. The problematic of this thesis deals with the exploration of digital spatial data by relying on haptic interactions. The goal is twofold: 1) understand how visually impaired people explore raised-line diagrams; and 2) offer haptic interaction techniques, based on personal and wearable devices, that allow visually impaired users to explore digital diagrams in different contexts (at home or at school, for example). To answer the first point, we conducted two studies on the exploration strategies of raised-line documents, according to the level of expertise of the users. We have shown that the strategies used depend on the expertise but also the type of document explored. To answer the second point, we proposed new interaction techniques based on the use of a smartwatch that allows localized feedback. We conducted two experimental studies regarding the design and evaluation of watch-based haptic interaction techniques. The first study focused on comparing the exploration of physical diagrams with that of virtual digital diagrams The results show that two of our interaction techniques allow for faster digital graphics exploration than the exploration of 3D graphics. Our second study aimed to develop and evaluate interaction techniques allowing the use of two hands while exploring digital content. The results show that bimanual strategies based on localized feedback improve digital diagrams exploration performance. The results of these studies highlight the benefits of bimanual haptic interaction. Combined with a device for tracking and tracking hands, interaction techniques developed on a connected watch could enable users to interact with digital content in many situations of everyday life

Full textAbstract:
Le travail présenté dans cette thèse est une contribution au dimensionnement et à la commande d’un générateur de type Cascade de Machines Asynchrones à Double Alimentation. Le modèle de la machine pour les simulations est basé sur une représentation modulaire qui découle du modèle de Park de deux machines asynchrones doublement alimentées distinctes, en respectant deux systèmes de référence. Le modèle dynamique est ensuite étendu pour décrire la machine dans un repère unifié. Cette représentation est cruciale pour le dimensionnement de la machine et la synthèse de la commande. Le domaine de fonctionnement de la cascade en régime permanent est exploré. Une méthode analytique générique est proposée pour établir les plages de puissances active-réactive. Les courbes limites sont définies par rapport aux grandeurs nominales de la machine. L’étude prend en compte l’effet de saturation du circuit magnétique. Il est prouvé que la capacité en puissance de la machine est déterminée par les valeurs maximales des courants statoriques et peut être soumise à plusieurs limitations. L’approche analytique est testée et validée par des mesures expérimentales. Deux cas sont considérés pour la commande de la cascade : un générateur raccordé au réseau et un générateur autonome. Pour la connexion au réseau l’application visée est les éoliennes de grande puissance. Une nouvelle méthode pour l’extraction de la puissance maximale d’une éolienne à vitesse variable est proposée. Le système est contrôlé dans le but de fournir une puissance maximale quasi-constante indépendamment des fluctuations du vent. En plus de l’optimisation de la puissance, le facteur de puissance est également ajusté selon les normes de raccordement standard imposées par les services système, et les limites de fonctionnement de l’unité intégrée. Une commande vectorielle sans capteur de tension, basée sur une orientation suivant un flux virtuel, est appliquée pour la régulation découplée des puissances active et réactive. Pour le fonctionnement en mode isolé, l’application visée est la génération électrique pour système avionique embarqué. Deux réseaux de distribution sont traités : réseau AC à fréquence fixe et réseau DC. Dans les deux cas, la commande est élaborée dans le but de maintenir une tension de sortie constante. Le fonctionnement de la cascade alimentant une charge triphasée déséquilibrée est également étudié. Des schémas de contrôle servant à la compensation du déséquilibre des tensions statoriques sont développés. Deux méthodes de compensation sont proposées : l’une basée sur le principe de deux repères tournants et l’autre sur un correcteur répétitif. Les approches présentées sont validées par simulation avec Matlab/Simulink et par expérimentationThis thesis is a contribution to the power sizing and the control of a Cascaded Doubly Fed Induction Generator (CDFIG). The machine model for simulation is based on a modular representation, derived from the Park model of two distinct Doubly Fed Induction Machines expressed in their own reference frames. The dynamic model of the cascaded machine is then extended to be described in a unified reference frame. This representation is convenient for the sizing of the machine and for the design of the controller. The steady state power operating margins of the cascaded machine are investigated. A generic analytic method is suggested to derive the active-reactive power domain. The limit curves are defined in terms of the rated quantities of the machine. The study takes into account the magnetic circuit saturation effect. It is proven that the power capability of the machine is determined by the stator current maximum values and is subject to several limitations. The analytical approach is tested and validated by experimental measurements. The CDFIG is controlled in grid-connected and standalone operation modes. In grid-connected application, the attention is paid to high power wind generation systems. A new maximum power tracking of a variable speed wind turbine is suggested. The generating plant is carried to provide a quasi-constant maximum power regardless wind fluctuations. In addition to active power optimization the power factor is adjusted according to the grid code requirements and the operating domain of the integrated unit. A virtual flux oriented vector control is applied for the decoupled regulation of active and reactive powers, leading to grid voltage sensorless operation. In standalone operating mode, the study treats in particular the embedded aircraft power system generation. Two distribution networks are considered: constant frequency AC network and DC network. In both cases, the control aims to maintain a constant output voltage. The operation of the CDFIG supplying unbalanced three-phase load is further explored. Control schemes to cope with unbalanced stator voltage conditions are developed. Two compensation methods are elaborated: the first dealing with dual rotating frames and the second is based on repetitive controller. Simulations with Matlab/Simulink software and experiments validate the control approaches

Development of the combustor of a ramjet can be achieved by connected pipe testing. Connected pipe testing is selected for combustor testing because pressure, temperature, Mach number, air mass flow rate can be simulated by this type of testing. Real time trajectory conditions and transition from rocket motor (booster) to ramjet operation can also be tested. The biggest advantage of connected pipe testing is the low operation cost and simplicity. Air mass flow rate requirement is less than the others which requires less air storage space and some components like supersonic nozzle and ejector system is not necessary.
In this thesis, design of a connected pipe test facility is implemented. Three main systems are analyzedair storage system, air heater system and test stand. Design of air storage system includes the design of pressure vessel and pressure &
flow regulation system. Pressure and flow regulation system is needed to obtain the actual flow properties that the combustor is exposed to during missile flight. Alternatives for pressure and air mass flow rate regulation are considered in this study. Air storage system designed in this thesis is 27.8 m3 at 50 bar which allows a test duration of 200 seconds at an average mass flow rate of 3 kg/s. Air heater system is utilized to heat the air to simulate the aerodynamic heating of the inlet. Several different combustion chamber configurations with different flame holding mechanisms are studied. The most efficient configuration is selected for this study. Combustion analysis of the air heater is performed by FLUENT CFD Code. Combustion process and air heater designs are validated using experimental data. Designed air heater system is capable of supplying air at a temperature range of 400-1000 K and mass flow rate range of 1.5-8 kg/s at Mach numbers between 0.1-0.5 and pressure between 2-8 bar. Finally the design of the test stand and ramjet combustor analysis are completed. 3D CAD models of the test stand are generated. Ramjet combustor that will be tested in the test setup is modeled and combustion analysis is performed by FLUENT CFD Code. The ramjet engine cruise altitude is 16 km and cruise Mach number is 3.5. Key-words: Air Breathing Engines, Ramjet, Connected Pipe, Direct Connect, Vitiator.

As the population ages, the use of information technology and telecommunications in healthcare delivery (often known as Connected Health, telehealth or e-health) has been proposed as a means of providing . patient-centred care to those with chronic conditions. Little research has been conducted into the involvement of community pharmacists in Connected Health delivery. This thesis aimed to investigate the potential role of community pharmacists in the delivery of Connected Health services. A systematic content analysis of print media was performed to explore reporting of Connected Health in UK and US newspapers. A qualitative interview study was conducted with community pharmacists and key stakeholders in Canada and Northern Ireland to gather their views on community pharmacist involvement in Connected Health. Informed by the latter qualitative study, an online questionnaire was distributed to community pharmacists in Northern Ireland to explore their views regarding their potential role in Connected Health. Finally, a feasibility study was carried out, in which community pharmacists sent patients mobile telephone medication reminders and remotely monitored their blood pressure . . Connected Health was positively reported by the print media in the US and the UK. Community pharmacist and key stakeholder interviewees were supportive of community pharmacist involvement in Connected Health, believing it would extend and promote ' their role. However, they had concerns regarding appropriate remuneration. Similar views were obtained from community pharmacist questionnaire respondents. The feasibility study showed that a community pharmacy-based Connected Health programme could be successfully implemented on a small scale. Participants involved were positive about community pharmacist involvement in Connected Health. Community pharmacist involvement in Connected Health has the potential to improve patient outcomes and ease pressure on the health service. However, barriers such as funding and general practitioner acceptance would need to be overcome and a sound evidence base established before routine pharmacist involvement becomes a reality.

La récente émergence des smartphones et des objets connectés a révolutionné le mode de vie des utilisateurs. Ces dispositifs ubiquitaires et équipés de plusieurs interfaces sans fil de communication, sont rapidement devenus indispensables dans la vie quotidienne des utilisateurs avec une utilisation intensive. Les interfaces sans fil de ces objets connectés émettent périodiquement des informations, certaines sont spécifiques aux utilisateurs et permettent par effet de bord d’identifier et de suivre leur déplacements. Le suivi des utilisateurs via les informations fortuitement émises par leurs périphériques sans fil se nomme le Wireless Physical Tracking. Les possibilités offertes par le Wireless Physical Tracking ont suscité un fort intérêt. Plusieurs applications se sont développés et ont permis d’apporter de l’innovation dans plusieurs domaines. Des sociétés de marketing l’utilisent afin de proposer à leurs clients de la publicité ciblée en fonction de leurs parcours dans leur zone d’activité. À une échelle plus grande, les villes intelligentes, ou smart-cities analysent le mouvement des utilisateurs afin d’apporter des services pour le confort des habitants. Enfin, dans le domaine de la recherche, les réseaux Ad-Hoc mobiles et autres DTN nécessitent de s’intéresser à cette pratique car l’étude de la mobilité des utilisateurs représentent un élément clé pour améliorer les performances de ce type de réseau. Cependant, la collecte de ces informations sans le consentement des utilisateurs ou sans qu’elles soient correctement protégées représentent un risque réel pour leur vie privée. C’est autour de ce contexte que s’articule cette thèse divisée en deux parties. La première présente les technologies PAN et WAN, l’état de l’art des méthodes de Wireless Physical Tracking et les contre mesures adoptés. La deuxième partie présentent les contributions de la thèse qui visent à proposer de nouvelles méthodes de suivi, analyser les performances de celles-ci face aux méthodes existantes et dans le cas particulier de l’application de crowd-localisation, à proposer des méthodes de suivi respectueuse de la vie privéeThe recent rise of smart-phones and connected objects has a deep impact its users lifestyle. In 2017, more than a billion and a half smart-phones were sold around the world. These ubiquitous devices, equipped with several wireless communication interfaces, have quickly become essential in the daily life of users with an intensive use. The wireless interfaces of these connected objects periodically transmit information on the network, some of which are user-specific and allow to identify and track their mobility. Tracking users by collecting the information generated by their wireless devices is called Wireless Physical Tracking. The opportunities offered by the Wireless Physical Tracking raised a lot of interest. Several applications have been developed and have brought innovation in several areas. Marketing companies use it to offer to their customers targeted advertising based on their movements in their area of activity. On a larger scale, Smart Cities or smart-cities analyse the movement of users in order to provide services for their inhabitants. Finally, in the field of research in mobile Ad-Hoc networks and DTNs, users mobility is a key element which need to be collected and analysed. However, the collection of this information without the consent of the users or without being properly protected induce a real risk to their privacy. It is around this context that this thesis is focused on. It’s divided into two parts. The first presents the PAN and WAN technologies, the state of the art of Wireless Physical Tracking methods and the adopted counter measures. The second part presents the contributions of the thesis which aims at developing new methods for Physical Tracking and analysing their performances compared to the existing methods. We first present an evaluate BPM, a bluetooth passive monitoring that allows to track the users of Classic Bluetooth device with a detection delay significantly lower than the methods previously used. We then focus on Bluetooth Low Energy and propose the use of a BLEB, a botnet of users tracking BLE objects with their smart-phones. Finally, we also focus on preserving users privacy through the proposal of PPCL, a privacy preserving crowdlocalisation method which allow to track users assets without being trackable

Full textAbstract:
Un véhicule autonome et connecté (ACV – pour Autonomous Connected Vehicle ) est un système cyber-physique où le monde réel et l’espace numérique virtuel se fusionnent. Ce type de véhicule requiert un processus de validation rigoureuse commençant à la phase de conception et se poursuivant même après le déploiement du logiciel. Un nouveau paradigme est apparu pour le monitorat continu des exécutions des logiciels afin d'autoriser des adaptations automatiquement en temps réel, systématiquement lors d’une détection de changement dans l'environnement d'exécution, d’une panne ou d’un bug. Ce paradigme s’intitule : « Models@Run.time ». Cette thèse s’inscrit dans le cadre des ACVs et plus particulièrement dans le contexte des véhicules qui collaborent et qui partagent leurs données d’une manière sécurisée. Plusieurs approches de modélisation sont déjà utilisées pour exprimer les exigences relatives au contrôle d'accès afin d’imposer des politiques de sécurité. Toutefois, leurs outils de validation ne tiennent pas compte les impacts de l'interaction entre les exigences fonctionnelles et les exigences de sécurité. Cette interaction peut conduire à des violations de sécurité inattendues lors de l'exécution du système ou lors des éventuelles adaptations à l’exécution. En outre, l’estimation en temps réel de l’état de trafic utilisant des données de type crowdsourcing pourrait être utilisée pour les adaptations aux modèles de coopération des AVCs. Cette approche n'a pas encore été suffisamment étudiée dans la littérature. Pour pallier à ces limitations, de nombreuses questions doivent être abordées:• L'évolution des exigences fonctionnelles du système doit être prise en compte lors de la validation des politiques de sécurité ainsi que les scénarios d'attaque doivent être générés automatiquement.• Une approche pour concevoir et détecter automatiquement les anti-patrons (antipatterns) de sécurité doit être développée. En outre, de nouvelles reconfigurations pour les politiques de contrôle d'accès doivent également être identifiées, validées et déployées efficacement à l'exécution.• Les ACVs doivent observer et analyser leur environnement, qui contient plusieurs flux de données dite massives (Big Data) pour proposer de nouveaux modèles de coopération, en temps réel.Dans cette thèse, une approche pour la surveillance de l'environnement des ACVs est proposée. L’approche permet de valider les politiques de contrôle d'accès et de les reconfigurer en toute sécurité. La contribution de cette thèse consiste à:• Guider les Model Checkers de sécurité pour trouver automatiquement les scénarios d'attaque dès la phase de conception.• Concevoir des anti-patterns pour guider le processus de validation, et développer un algorithme pour les détecter automatiquement lors des reconfigurations des modèles.• Construire une approche pour surveiller en temps réel les flux de données dynamiques afin de proposer des adaptations de la politique d'accès lors de l'exécution.L’approche proposée a été validée en utilisant plusieurs exemples liés aux ACVs, et les résultats des expérimentations prouvent la faisabilité de cette approcheAutonomous Connected Vehicles (ACVs) are Cyber-physical systems (CPS) where the computationalworld and the real one meet. These systems require a rigorous validation processthat starts at design phase and continues after the software deployment. Models@Runtimehas appeared as a new paradigm for continuously monitoring software systems execution inorder to enable adaptations whenever a change, a failure or a bug is introduced in the executionenvironment. In this thesis, we are going to tackle ACVs environment where vehicles tries tocollaborate and share their data in a secure manner.Different modeling approaches are already used for expressing access control requirementsin order to impose security policies. However, their validation tools do not consider the impactsof the interaction between the functional and the security requirements. This interaction canlead to unexpected security breaches during the system execution and its potential runtimeadaptations. Also, the real-time prediction of traffic states using crowd sourcing data could beuseful for proposition adaptations to AVCs cooperation models. Nevertheless, it has not beensufficiently studied yet. To overcome these limitations, many issues should be addressed:• The evolution of the system functional part must be considered during the validation ofthe security policy and attack scenarios must be generated automatically.• An approach for designing and automatically detecting security anti-patterns might bedeveloped. Furthermore, new reconfigurations for access control policies also must befound, validated and deployed efficiently at runtime.• ACVs need to observe and analyze their complex environment, containing big-datastreams to recommend new cooperation models, in near real-time.In this thesis, we build an approach for sensing the ACVs environment, validating its accesscontrol models and securely reconfiguring it on the fly. We cover three aspects:• We propose an approach for guiding security models checkers to find the attack scenariosat design time automatically.• We design anti-patterns to guide the validation process. Then, we develop an algorithmto detect them automatically during models reconfigurations. Also, we design a mechanismfor reconfiguring the access control model and we develop a lightweight modularframework for an efficient deployment of new reconfigurations.• We build an approach for the real-time monitoring of dynamic data streams to proposeadaptations for the access policy at runtime.Our proposed approach was validated using several examples related o ACVs. the results ofour experimentations prove the feasibility of this approach

This study starts with the design of a reversible airfoil rib for stopped-rotor applications, where the sharp trailing-edge morphs into the rounded leading-edge, and vice-versa. A NACA0012 airfoil is approximated in a piecewise linear manner and straight, rigid outer profile links used to define the airfoil contour. The end points of the profile links connect to control links, each set on a central actuation rod via an offset. Chordwise motion of the actuation rod moves the control and the profile links and reverses the airfoil. The paper describes the design methodology and evolution of the final design, based on which two reversible airfoil ribs were fabricated and used to assemble a finite span reversible rotor/wing demonstrator. The profile links were connected by Aluminum strips running in the spanwise direction which provided stiffness as well as support for a pre-tensioned elastomeric skin. An inter-rib connecter with a curved-front nose piece supports the leading-edge. The model functioned well and was able to reverse smoothly back-and-forth, on application and reversal of a voltage to the motor. Navier Stokes CFD simulations (using the TURNS code) show that the drag coefficient of the reversible airfoil (which had a 13% maximum thickness due to the thickness of the profile links) was comparable to that of the NACA0013 airfoil. The drag of a 16% thick elliptical airfoil was, on average, about twice as large, while that of a NACA0012 in reverse flow was 4-5 times as large, even prior to stall. The maximum lift coefficient of the reversible airfoil was lower than the elliptical airfoil, but higher than the NACA0012 in reverse flow operation.

Full textAbstract:
Abstract The successful application of plastic liners for flowline corrosion control requires connector and termination technologies to link individually lined pipe sections. This review describes typical applications, installation procedures, performance and cost of the different connectors which have thus far been employed, both onshore and offshore, on lined flowlines. Possible future developments will be described. Onshore, the most economical and widely proven connection is the raised face flange type, constructed either using pre-manufactured PE flanges fusion welded to the end of the installed liner, or using the liner itself formed / flared around the face of the steel flange. Offshore, developments have centred on the need for lines to be reeled during installation. This has led to the use of welded connectors, in which liners are mechanically terminated either side of the tie-in welds, with alloy steel pup pieces providing corrosion resistance in between.

Abstract In the search to drive value for Corrosion & Asset Integrity Management, the Company has embarked on a journey towards industrial mobility. Mobile, internet-connected devices in industry, similar to the smart devices used on our day-to-day activities, are the future of our industrial operations to enable higher effectiveness by capturing event data in real time, allowing fast deployment of findings from the field for quicker data assessment, and supporting people empowerment. This paper will share the Company’s journey toward industrial mobility, for the monitoring of corrosion control activities (such as operational pigging, corrosion coupon and corrosion inhibitor residual), by the use of smart devices. An application was developed to capture the field information in the smart device and further connect to a centralized/organized database with automated data processing (analysis, trends, graphs, dashboards and notifications) to ensure high quality information for the Corrosion Control Engineers to proactively action accordingly.

Abstract This paper illustrates the results gained during the first three years of cathodic protection application to Frejus highway viaducts in northern Italy. CP applications deal with corrosion control of chloride contaminated structures (cathodic protection application properly said) and the corrosion prevention of new non-contaminated structures, constructed with incorporated cathodic protection systems (so-called cathodic prevention). Both normal and post-tensioned structures are present: in the latter case the problems connected with the risk of hydrogen embrittlement of the tendons are discussed. The paper illustrates also the computerized system for gathering and monitoring data and the criteria adopted to evaluate and control the cathodic protection and cathodic prevention conditions as well as to avoid overprotection.

Full textAbstract:
Non-metallic, flexible, thin, microchannel heat exchangers made from heat-sealable polyimide films have recently been developed for refrigeration and air-conditioning applications. In order for these heat exchangers to function properly and independently, robust and reliable connectors are needed. The connectors must be easy to manufacture and assemble, hold high pressures without leaking, and have the ability to connect to standard tubing and piping and different heat exchangers together in series and parallel. Three uniquely different connector designs have been developed, manufactured, and tested. The first includes a machined metal connector internally embedded within the heat exchanger that is capable of holding pressures up to 1.03 MPa. The second connector design includes a two-piece polymer assembly containing an O-ring used to seal around the inlet and outlet holes of the heat exchanger. The design incorporates a 10-degree wedge that creates the sealing force when fully assembled with the heat exchanger and has been pressure tested to 2.07 MPa without leaking. A variation of the design allows multiple heat exchangers to connect in series and in parallel. Finally, the third design contains no additional parts and connects two heat exchangers together by thermally bonding the inlet of one heat exchanger to the outlet of another. The thermally bonded connection was able to hold pressures greater than 2.07 MPa.

Full textAbstract:
Carbon nanotubes (CNTs) have been reported to have excellent thermal and mechanical properties over the past two decades. However, the practical application of CNT-based technologies has been limited, due to the inability to transform the excellent properties of single CNTs into macroscopic applications. CNT network structure connects CNTs and can be possibly scaled up to macro-scale CNT-based application. In this paper, nonequilibrium molecular dynamics is applied to investigate thermal transport across two CNTs connected longitudinally by molecular linkers. We show the effect of different types and lengths of molecular linkers on interfacial thermal conductance. We also analyze the density of vibrational normal modes to further understand the interfacial thermal conductance between different molecular linkers and CNTs. These results provide guidance for choosing molecular linkers to build up large-scale CNT-based network structures.

Full textAbstract:
Most recent grid codes require wind turbines to contribute to the recovery of frequency drops in the grid. More of the recently build wind turbines use variable speed generators. Unlike fixed speed generators, these generators do not naturally contribute to the recovery of the frequency drop since the rotor rpm is decoupled from the grid frequency. This decoupling is achieved by controller and power conditioning units. The studies reviewed in this paper focused on the design of such a controller so that the wind turbine could react to frequency drops. Another approach to responding to frequency drops is to connect an energy storage system to the DC bus of variable speed generator. Flywheels have been used as energy storage systems to fill energy gaps in several applications and can be used for frequency recovery application for wind turbines as well. The objective of this study was to demonstrate the improvement of frequency stability of wind turbines connected to electrical grids in the presence of flywheel energy storage systems (FESS). Studies reviewed show that FESS can enhance the power quality and frequency stability of wind turbines connected to an electrical grid.

Full textAbstract:
Every year, over 60,000 work zone crashes are reported in the United States (FHWA 2016). Such work zone crashes have resulted in over 4,400 fatal and 200,000 non-fatal injuries in the last 5 years (FHWA 2016, BLS 2014). Apart from the physical and emotional trauma, the annual cost of these injuries exceeds $4 million-representing significant wasted resources. To improve work zone safety, this research developed a system architecture for unveiling high-risk behavioral patterns among highway workers, equipment operators, and drivers within dynamic highway work zones. This research implemented the use of a connected virtual environment, which is an immersive hyper-realistic and virtual environment where multiple agents (e.g. workers, drivers, and equipment handlers) control independent simulators but experience an interactive and shared experience. For this project, the team conducted an in-depth analysis of accident investigation, simulated accident scenarios, and tested diverse interventions to prevent high-risk behavior. Overall, the research improved understanding of behavioral patterns that lead to injuries and fatalities of highway workers in order to better protect them in high-risk work environments. As part of making transportation smarter, this project contributes to smart behavioral safety analysis.

Full textAbstract:
5G is the next generation of mobile communications technology. It follows on from the previous generations of mobile technology, such as 3G and 4G. 5G is expected to improve on previous mobile technologies by providing faster, lower latency (response time) mobile broadband connections and being able to connect a greater number of devices to a mobile network in a particular area while maintaining good quality connections. 5G mobile broadband will be the first widespread application of the technology. However, in the longer term it may have applications in other sectors.

Full textAbstract:
(CAP) are transforming activities across the UK construction sector. CAP offers potential in a wide range of applications, for example: remote collection of data for design; geofencing of plant operation; semi-autonomous extraction and movement of materials; offsite and robotic construction. However, this transformation presents a challenge to the sector. The introduction of CAP technology lacks a unified approach. Practice differs across construction sites and between clients. As a result, CAP deployment varies significantly across sites and information flow between organisations is slow. The industry is developing a strong understanding of the potential presented by CAP, with exciting examples of new technology being applied in practice. However, the community is concerned over the pace and practicality of implementing new methods, in context of the current approach to commissioning and delivering construction projects. Because there is no clear direction to encourage the use of CAP, the industry must bear all the risks of investing in new systems. These investments are made in an environment where there’s a lack of certainty about the capability of the technology, and a lack of clarity about the risks, liabilities and acceptability of its use. What does the Roadmap describe? The Roadmap has been developed collaboratively with over 75 organisations. Questionnaires and workshops identified the actions required to overcome technical, business and legislative challenges affecting successful delivery of the vision. The Roadmap brings these together in nine workstreams, each focusing on key areas identified by stakeholders. These workstreams would be delivered in parallel through industry-wide collaboration.

<div class="section abstract"><div class="htmlview paragraph">Recently, there has been a slight increase in interest in the use of responder-to-vehicle (R2V) technology for emergency vehicles, such as ambulances, fire trucks, and police cars. R2V technology allows for the exchange of information between different types of responder vehicles, including connected and automated vehicles (CAVs). It can be used in collision avoidance or emergency situations involving CAV responder vehicles. The benefits of R2V are not limited to fully autonomous vehicles (e.g., SAE Level 4), but can also be used in Level 2 CAV scenarios. However, despite the potential benefits of R2V, discussions on this topic are still limited.</div><div class="htmlview paragraph"><b>Responder-to-Vehicle Technologies for Connected and Autonomous Vehicles</b> aims to provide an overview of R2V technology and its applications for CAV systems, particularly in the context of collision avoidance features. The responder vehicles in question can be autonomous or non-autonomous. It is hoped that it will provide valuable information and knowledge on vehicle connectivity and automation in the current automotive and mobility ecosystem, enabling the development of safer and more reliable autonomous driving technology.

The Indiana Department of Transportation (INDOT) manages and maintains over 28,000 miles of roadways. Maintenance of the roadways includes pavement repair in the summer as well as snow removal and de-icing in the winter. The prioritization of assets during winter storm events is crucial and impacts travel and safety. The objective of this project was to identify and develop tools INDOT could provide its operators to effectively perform winter operation de-icing activities. This project examined application methods and data to provide analytics and make data-driven decisions for state-wide deployment and operations. Discovery of calibration metrics partnered with fleetwide telematics enabled the development of analytic dashboards that allowed real-time evaluations and adjustments to be made during winter operation activities. These tools will allow the agency to better treat and enhance safety for road users.
