ptp++: A Precision Time Protocol Simulation Model for OMNeT++ / INET

Precise time synchronization is expected to play a key role in emerging distributed and real-time applications such as the smart grid and Internet of Things (IoT) based applications. The Precision Time Protocol (PTP) is currently viewed as one of the main synchronization solutions over a packet-switched network, which supports microsecond synchronization accuracy. In this paper, we present a PTP simulation model for OMNeT++ INET, which allows to investigate the synchronization accuracy under different network configurations and conditions. To show some illustrative simulation results using the developed module, we investigate on the network load fluctuations and their impacts on the PTP performance by considering a network with class-based quality-of-service (QoS) support. The simulation results show that the network load significantly affects the network delay symmetry, and investigate a new technique called class probing to improve the PTP accuracy and mitigate the load fluctuation effects.Comment: Published in: A.

Political Theology Versus Public Theology: Reclaiming the Heart of Christian Mission

Christian theology has always viewed itself in relation to two communities: the church and the wider public. Political theology attempts to expose incoherencies by highlighting theological themes in “secular” society. Public theology, meanwhile, accepts that wider political communities have their own autonomy. The work of Public Theology is to bring together insights from the gospel with initiatives from wider political movements in Government, Economic Structures and Civil Society for the benefit of all citizens. In this thesis, I explore the historical development of Political Theology with the aid of Kirwan and Phillips. I examine the evolution of Public Theology from Political Theology through Tracy and Smit. I then propose that Public Theology offers more public participation in secular society than Political Theology supported by Cavanaugh. Finally, I assert that Public Theology is made possible through the sacrament of baptism

La pêcherie d'anguille du Kamouraska : essor et déclin d'une culture et d'une ressource

Les pêcheries d’anguilles ont été une activité emblématique de l’évolution de la culture de la région du Kamouraska et une source identité pour ses pêcheurs. Son apparence rappelant celle du serpent et les mystères entourant sa vie dans les fonds marins font de ce poisson l’objet de multiples interprétations dans les croyances de plusieurs peuples. De son essor à son déclin, la géographie historique de la pêche à l’anguille est un moyen d’explorer la relation plus large entretenue par les habitants du Kamouraska avec leur environnement. D’abord une partie intégrale de la transhumance des Amérindiens, elle était, avec l’agriculture, tout aussi essentiel à la subsistance des colons français de la région et est devenu économiquement importante pour les marchés qui émergent dans les XIXe et XXe siècles. Le déclin des pêcheries d’anguilles dans les années 1970 témoigne des effets à long terme de la dégradation de la santé du Saint-Laurent. Mots-clés : Anguilles, pêche à anguille, géographie historique, Nature et Culture, gestion écosystémique, identité, développement socioéconomique, Kamouraska, Maoris.The history of the eel fishery has been an activity emblematic of the evolving culture of the Kamouraska region and a source of identity for the region’s fishing population. The snake-like appearance of the eel and its mysterious life underwater made it a fish subject to multiple interpretations in the belief systems of several peoples. From its rise to its decline, the historical geography of the eel fishery is a medium for exploring the larger relationship of the peoples of Kamouraska with their environment. An integral part of the transhumance of First Nations peoples, it was equally an essential part of the fishing and agricultural subsistence activities of the French colonists of the region and became an economically important market activity in the 19th and 20th centuries.. The decline of the eel fishery in the 1970’s provides testimony to the long-term effects of environmental degradation of the St. Lawrence River. Keywords: Eel, Eel fishery, historical geography, Nature and culture, ecosystem management, identity, social and economical development, Kamouraska, Maoris

La thérapie par observation d’action (TOA) dans la maladie de Parkinson

Travail d'intégration réalisé dans le cadre du cours PHT-6113.Problématique: La maladie de Parkinson (MP) est une pathologie neurodégénérative affectant les noyaux gris centraux et est caractérisée par quatre signes moteurs cardinaux: tremblements au repos, bradykinésie/akinésie, rigidité et instabilité posturale. Les symptômes limitent la performance aux tâches fonctionnelles et augmentent le risque de chutes. Actuellement, les interventions en physiothérapie avec les personnes parkinsoniennes sont limitées. La thérapie par observation d’action (TOA) est une approche de rééducation prometteuse. Objectifs: Décrire la physiopathologie de la MP, les outils cliniques pour évaluer les parkinsoniens, les particularités liées aux tâches fonctionnelles et les bases neurophysiologiques sous-tendant la TOA dans le but de déterminer les lignes directrices de cette thérapie auprès des parkinsoniens. Stratégie méthodologique: Les bases EMBASE, MEDLINE, PubMed et Cochrane ont été consultées pour la recension d’articles en lien avec les objectifs. Résultats: Aucun principe d’application de la TOA n’est décrit précisément et aucun consensus n’est établi sur les meilleurs outils d’évaluation à utiliser avec la clientèle parkinsonienne pour mesurer l’effet de la TOA. L’analyse de la littérature permet de suggérer trois tâches fonctionnelles à pratiquer avec la TOA, soit l’atteinte d’une cible avec iii le membre supérieur, le transfert assis-debout et la marche. Il est aussi possible de proposer certaines lignes directrices pour l’évaluation clinique et la mise en pratique de la TOA. Conclusion: Le projet a permis de proposer certaines lignes directrices pour l’utilisation de la TOA chez les parkinsoniens. Ces recommandations seront présentées aux cliniciens afin de les outiller pour appliquer la TOA et étudier ses effets avec cette clientèle

An asynchronous and task-based implementation of Peridynamics utilizing HPX -- the C++ standard library for parallelism and concurrency

On modern supercomputers, asynchronous many task systems are emerging to address the new architecture of computational nodes. Through this shift of increasing cores per node, a new programming model with the focus on handle the fine-grain parallelism of this increasing amount of cores per computational node is needed. Asynchronous Many Task (AMT) run time systems represent an emerging paradigm for addressing fine-grain parallelism since they handle the increasing amount of threads per node and concurrency. HPX, a open source C++ standard library for parallelism and concurrency, is one AMT which is confirm with the C++ standard. Which means that HPX's Application Programming Interface (API) is confirm with its definition by the C++ standard committee. For example for the concept of futurization the hpx:future can be replaced by std::future without breaking the API. Peridynamics is a non-local generalization of continuum mechanics tailored to address discontinuous displacement fields arising in fracture mechanics. As many non-local approaches, peridynamics requires considerable computing resources to solve practical problems. This paper investigates the implementation of a peridynamics EMU nodal discretization in an asynchronous task-based fashion. The scalability of asynchronous task-based implementation is to be in agreement with theoretical estimations. In addition, to the scalabilty the code is convergent for implicit time integration and recovers theoretical solutions. Explicit time integration, convergence results are presented to showcase the agreement of results with theoretical claims in previous works

Parents’ reading-related knowledge and children’s reading acquisition

Teacher reading-related knowledge (phonological awareness and phonics knowledge) predicts student reading, however little is known about the reading-related knowledge of parents. Participants comprised 70 dyads (children from kindergarten and grade 1 and their parents). Parents were administered a questionnaire tapping into reading-related knowledge, print exposure, storybook reading, and general cultural knowledge. Children were tested on measures of letter–word knowledge, sound awareness, receptive vocabulary, oral expression, and mathematical skill. Parent reading-related knowledge showed significant positive links with child letter–word knowledge and sound awareness, but showed no correlations with child measures of mathematical skill or vocabulary. Furthermore, parent reading-related knowledge was not associated with parents’ own print exposure or cultural knowledge, indicating that knowledge about English word structure may be separate from other cognitive skills. Implications are discussed in terms of improving parent reading-related knowledge to promote child literacy
