    1933 — The occupational adjustment of the British immigrant in Montreal.
    Abstract

    It is perhaps not surprising that existing studies of British migration to Canada deal primarily with settlement on the land. The Canadian government has made strenuous efforts to encourage immigration of this sort; there is something of glamour, too, about the movement to the last frontier on the prairies of western Canada. Yet all the while immigration hasbeen flowing in equal volume into the industrial oentres of the east. While the eyes of the nation were fixed on schemes of Empire settlement, tens of thousands of Br1tishers wereslipping almost unnotioed into Toronto, Montreal and other metropolitan areas.

    1996 — Early cretaceous lepidosaurs (reptilia:diapsida) from central México and the phylogeny of lepidosauromorphs
    Abstract

    Four new lepidosaurs from the Early Cretaceous deposits of the Tlayua Quarry, Central Mexico are described, establishing their phylogenetic relationships using cladistic methodology. These lepidosaurs have unique characters never present in related forms suggesting that they have evolved in isolated environments far from immediate ancestors, indicating the insular nature of the quarry. The sphenodontid Pamizinsaurus tlayuaensis is covered with unique rows of small rounded osteoderms that could have protected it against predation in open environments. Ankylosphenodon pachyostoseus has unusual teeth ankylosed deep into the dentary with probable continuous growth, which combined with propalinal action of a deep lower jaw suggest …  Read more

    2026 — Development of the 3D Printing Process for Recycled Glass Fibre Reinforced Composite Filaments
    Abstract

    Pour protéger l’environnement, la fibre de verre recyclée provenant d’anciennes éoliennes usagées peut être utilisée pour produire des filaments renforcés de fibres présentant de meilleures propriétés mécaniques pour l’impression 3D. Dans cette étude, de la fibre de verre est incorporée à une concentration de 10 % en poids dans du polyéthylène téréphtalate glycol (PETG). Le procédé d’impression a consisté à optimiser trois paramètres clés : la vitesse d’impression, la température de la buse et la température du plateau. L’optimisation visait à déterminer les valeurs idéales pour chaque paramètre afin d’obtenir la résistance et la rigidité les plus élevées dans les …  Read more

    2015 — Development of creep-resistant Al-Si cast alloys strengthened with nanoscale dispersoids
    Abstract

    This doctoral thesis aimed at creating thermally stable precipitates (dispersoids) via the use of slow-diffusing elements, Ni, Mo and Mn to develop creep resistant Al-Si cast alloys to be used for Diesel engine applications above 250°C and in the 20-30MPa stress range. CALPHAD-based thermodynamic calculations (FactSage, ThermoCalc) were carried out to determine the phase selections and solidification paths in the alloy systems. The precipitates and their influence on creep deformation were studied via conventional and high-resolution transmission electron microscopy.Ni up to 0.6wt.% increased the strength of the base alloy, Al-7Si-0.5Cu-0.3Mg at 300°C, but lowered the creep resistance because of the …  Read more

    2015 — Cooperative coding and decoding schemes in cellular networks
    Abstract

    In a cellular network, universal frequency reuse can be employed in neighboring cells to achieve higher spectral efficiency. In this case cell-edge user equipments (UE’s) may experience severe inter-cell interference (ICI), which can impair the reliability of the network. Interference-aware multicell coordination, known as coordinated multipoint transmission/reception (CoMP), has been proposed to control ICI such that UE’s can even benefit from it. CoMP schemes that can be deployed without the need for a feedback structure are referred to as open-loop CoMP schemes. The objective of this research is to study distributed coding/decoding schemes in a multiuser multicell system with open-loop …  Read more

    2022 — Chalcogenide and ZBLAN based optical fiber components
    Abstract

    La gamme de longueurs d’infrarouge à onde moyenne (MIR) du spectre électromagnétique (2-20 μm) coincide avec les fréquences vibratoires fondamentales d’une grande majorité de molécules, d’ou son importance cruciale pour la détection chimique, la spectroscopie moléculaire et la prise d’empreintes digitales. Le développement des technologies MIR efficacesnécessite des composantes à fibre optique. Actuellement, les composantes à fibre optique commercialement disponibles sont principalement constituées de silice, qui par nature est limitée à la fenêtre de fonctionnalité de transmission de la fibre de silice (jusqu’à 2 μm), et donc, ne conviennent pas aux applications d’MIR. D’autre part, les fibres de chalcogénure etde …  Read more

    2017 — Fragility assessment and reliability analysis of transmission lines subjected to climatic hazards
    Abstract

    Un élément important de l'analyse probabiliste est la définition des fonctions d'état limite. Deux approches sont proposées: une approche par composante et une approche systémique. L'approche par composante utilise une approche novatrice basée sur les concepts de la théorie d'apprentissage statistique (SLT) et la généralisation des intervalles Vapnik-Chervonenkis (VC) pour contrôler le niveau de complexité du modèle. La procédure est utilisée pour identifier un modèle représentatif équivalent à un modèle plus complexe basé sur les éléments finis. Le modèle représentatif équivalent est utilisé afin de dériver les courbes de fragilité des composants et du système et leur couplage avec les …  Read more

    2025 — Development of a HVAC System for Moderating Humidity Removal Efficiency
    Abstract

    Le fonctionnement des systèmes de chauffage, ventilation et climatisation (CVC) pendant l'été est souvent suffisant pour répondre aux besoins de refroidissement sensible et latent d’un bâtiment et de ses occupants. Cependant, la charge d'humidité peut être considérablement plus importante que la capacité du climatiseur à l’éliminer pendant les périodes de l'année où les charges sensibles sont plus faibles. Cela entraîne des conditions intérieures inconfortables et des niveaux élevés d'humidité relative intérieure (HR). Pour condenser l'humidité, les systèmes CVC conventionnels refroidissent d'abord l'air en dessous du point de rosée, pour éliminer la vapeur d’eau. Le système réchauffe ensuite l'air à une …  Read more

    2008 — The effect of very high temperature deformation on the hot ductility of a V-microalloyed steel /
    Abstract

    The loss of hot ductility (HD) of steel during continuous casting is usually attributed to the intergranular precipitation of V and Nb (C, N) as well as segregation of atoms to grain boundaries. This loss of hot ductility in the temperature range 700--1100°C in carbon and low alloy steels is related to transverse surface cracks during the straightening operation of the continuous casting process of steel. An additional problem, found in peritectic steels, is its very coarse as cast structure, which is very prone to cracking during the straightening stage. In this regard, two major solutions have been suggested to …  Read more

    2023 — Identification of new genes for recurrent hydatidiform mole pregnancies
    Abstract

    La môle hydatiforme (MH) est une complication rare de la grossesse caractérisée par une prolifération excessive du trophoblaste et un développement embryonnaire anormal. La môle sporadique affecte 1 grossesse sur 600. Parmi les femmes ayant eu une môle, 1 à 4 % développeront une autre môle, ces patients ont des môles hydatiformes récurrentes (MHR). Les mutations récessives dans NLRP7 et KHDC3L étaient connues pour être à l'origine de la MHR avec un génotype biparental diploïde. NLRP7 et KHDC3L sont membres du complexe maternel sous-cortical (SCMC).NLRP7 et KHDC3L expliquent 60% des cas de MHR. En 2018, des mutations dans PADI6 et …  Read more

    2023 — Cruelty and the example of Agathocles
    Abstract

    Dans cet article, je reconstruis la défense de la cruauté de Machiavel. Pour ce faire, je me concentrerai sur l'exemple d'Agathocle Sicilien dans le chapitre 8 du Prince, où Machiavel énonce les conditions dans lesquelles le recours à la cruauté se justifie. Je ferai valoir que l'exemple d'Agathocle démontre que Machiavel considérait la cruauté comme une tactique politique anti-oligarchique. Ce faisant, je vais mettre en évidence comment la défense de Machiavel contre la cruauté diffère de la compréhension contemporaine de celle-ci. Je vais notamment examiner le récit de Judith Shklar sur la cruauté comme une infraction des forts contre les …  Read more

    2017 — All-optical signal processing and microwave photonics using nonlinear optics
    Abstract

    De nombreuses techniques du traitement du signal optique ont été étudiées dans la littérature, dont la plupart sont basés sur l'optique non linéaire telle que le deuxième ordre et troisième ordre des effets non linéaires. Une large gamme de moyens non linéaires sont utilisés pour l'exécution de ces applications du traitement du signal optique non linéaire tels que les fibres optiques, les amplificateurs optiques à semi-conducteurs, et différents types de guides d'ondes optiques. Dans cette thèse, nous utilisons l'optique non linéaire pour effectuer des applications d'un traitement du signal optique et d'un photonique appliquée aux micro-ondes. Nous proposons et démontrons …  Read more

    2017 — Color measurement at low light levels
    Abstract

    Ambient light level drives the human visual system into three phases: scotopic, mesopic and photopic vision. In photopic conditions, light level is far above the visual system activation threshold; cones are mainly responsible for our color vision and rods are saturated due to their higher sensitivity to light. Mesopic range refers to the condition where both cones and rods are active and contribute to color vision. In scotopic vision, the light level is very low such that cones are inactive (i.e. there is no color vision); however, rods are still able to contribute to our vision.Low light vision is of …  Read more

    1981 — The determination of surface deformations by holographic-electro-optical processing /
    Abstract

    This thesis is concerned with the experimental determination of surface displacements of material foils by means of an automatic evaluation of the holographic interferograms obtained in testing. The experimental work utilizes a newly developed method referred to as the "holographic-electro-optical" technique that employs a specially designed microcomputer unit. The experimental procedure and the microcomputer organization are fully described. The application of this technique is illustrated by the evaluation of strain field and thickness changes at a large number of points on both sides of a commercial newsprint paper sample subjected to uniaxial loads. Furthermore, a new quantity called the "volumetric …  Read more

    2020 — Medial measures for recognition, mapping and categorization
    Abstract

    L'analyse de la forme visuelle joue un rôle fondamental dans la perception par l'humain et par l’ordinateur, qui permet de déduire des propriétés d’objets et de scènes du monde physique. Les approches mathématiques pour décrire la forme visuelle peuvent bénéficier de l'utilisation de représentations qui capturent simultanément les propriétés du contour d'un objet ainsi que son intérieur. Motivée par le succès des modèles médiaux, ma thèse de doctorat revisite les calculs liés à l’axe médian et aux flux sortants moyens du gradient de la fonction de distance euclidienne à partir d’une frontière, puis propose des solutions à trois problèmes distincts …  Read more

    Ce mémoire propose une méthode pour calculer des représentations squelettiques en fonction du flux moyen décrit par le gradient de la fonction de distance Euclidienne aux limites d'un objet 2D qui rétrécit. La méthode originale développée par Dimitrov et al. [17] est ensuite optimisée afin de calculer des invariants de flux plus rapidement. Une relation entre l'AOF et l'angle de l'objet aux extrémités (aux points de branches et des points réguliers du squelette) est exploitée afin d'obtenir une reconstruction plus précises des limites de l'objet par rapport aux travaux précédents. En utilisant cette implémentation optimisée, de nouvelles mesures de simplification …  Read more

    2007 — The typical trajectory of response inhibition, sustained attention, and delay aversion : the nature of their relationship with naming speed
    Abstract

    Although the behavioral phenotype of disorders such as attention deficit hyperactivity disorder (ADHD) and reading disability (RD) are well established, to date, few studies have assessed the association between the core cognitive characteristics implicated in each disorder. And fewer yet have addressed this in a sample of typically developing preschool and young school age children when such skills are developing and maturing. The present study focused on providing a typical trajectory of attentional and inhibitory performance alongside delay aversion and their association with naming speed, a basic cognitive process involved in the acquisition of later reading skills. Alongside the developmental …  Read more

    2005 — Online characterization of viscoelastic and stress-relaxation behavior in thermoforming
    Abstract

    The thermoforming process is subject to a lot of variability with regard to the viscoelastic properties of the material, and the level of residual stresses caused by the manufacturing (extrusion and calandering) process of a plastic sheet. A robust control system must be able to identify and adjust to these perturbations in real time during the thermoforming process. The research project proposes two process sub-models, which predict the behavior of the elastic modulus and the level of frozen-in stresses. These two sub-models will be used in a model based control system, consisting of a number of process submodels encompassing different …  Read more

    1957 — The fiscal system of Jordan.
    Abstract

    Before the First World War, the territory that comprised Transjordan was part of the Ottoman Empire. For administrative purposes, Transjordan was included in the province (vilayet) of Syria which itself was divided into 4 districts (sanjaks). After the defeat of the Turks in 1918, the Ottoman Empire disintigrated and Emir Faisal, son of Sherif Hussein ruler of the Hejaz, was proclaimed King on March 8th 1920. This, however, conflicted with the policy of the Allies as revealed by the Sykes-Picot secret Agreement concluded in the spring of 1916 and which contemplated the division of that area into spheres of influence.  Read more

    2019 — Food security, health and well-being in times of financial and political crisis in Brazil
    Abstract

    Background: Food security, health and well-being for all are the second and third Sustainable Development Goals (SDGs) of the 2030 Agenda set by the United Nations. Although global efforts have resulted in improvements in food security, health and well-being across the world, studies have shown that economic and political crises can rapidly undermine achievements in these areas and prevent countries from reaching both SDGs. However, the literature lacks continuous monitoring of food security, health, and well-being in affected countries; and despite Brazil's food security policies and universal healthcare system are recognized as a model for developing countries, no one has …  Read more

    L'approche proposée par Śliwerski, Zimmermann, et Zeller (SZZ) pour identifier les changements de code qui induisent des corrections trace à l'envers d'un commit qui corrige un défaut pour trouver des commits qui sont impliqués dans cette correction. Cette approche est au cœur des études de caractéristiques des changements qui induisent des corrections, ainsi que la variante populaire de prédiction des défauts ‘`Just in Time" (JIT). Cependant, certains types de commits sont invisibles à l’approche SZZ. Nous nous référons à ces commits comme des commits fantôme: ``Ghost Commits".

    2024 — Exploiting tumor inflammation to increase the therapeutic impact of biguanides in oncology
    Abstract

    Breast cancer is the most common cancer among Canadian women; 1 in 8 women are expected to develop breast cancer in their lifetime. Breast cancer is grouped into four distinct types, which informs treatment strategies and patient outcomes. Indeed, some of these breast tumor types are more likely to develop therapeutic resistance, leading to relapse for these women. Moreover, regardless of tumor type, treatments are rarely curative for women who are diagnosed with breast cancers at an advanced stage, including metastatic disease. For these reasons, identifying therapies that target essential vulnerabilities is necessary for improving survival outcomes of women with …  Read more

    Le virus de l’hépatite C (VHC) recrute deux molécules du microARN humain spécifique au foie, miR-122, à deux sites (site 1 et site 2) à l’extrémité 5´ de son génome, et ces interactions favorisent l’accumulation de l’ARN viral. De récentes études ont mené à l’identification de trois rôles spécifiques de miR-122 dans le cycle de vie du VHC : 1) il agit comme ARN chaperon, ou « riboswitch », et promouvoit le changement de configuration d’une structure alternative appelée SLIIalt (tige-boucle alternative) vers la structure fonctionnelle de l’IRES (internal ribosomal entry site), composé des tige-boucles SLII à IV; 2) il …  Read more

    1992 — Bilingual aphasia : efficacy and generalization of bilingual therapy
    Abstract

    The present study was conducted in order to investigate the effects of bilingual therapy on the naming skills of a bilingual aphasic patient. The nature of the word-finding difficulties of a French-English bilingual aphasic subject was assessed. Theory-based anomia therapy was administered to the patient first in English and then in French to explore within- and across-language treatment effects. General language skills were also assessed before and after therapy. Results revealed significant improvement in naming of treated words, but very limited generalization to untreated items in only one of the languages. Transfer of therapy effects from treated to untreated language …  Read more

    1998 — The professionalization of nursing : a study of the changing entry to practice requirements in New Brunswick
    Abstract

    This study is about the professionalization of nursing. Nursing leaders at the national level and in New Brunswick initiated a new education policy requiring the baccalaureate degree as entry to practice. The new education policy would eliminate the diploma programs which are two to three years in length in favour of the baccalaureate degree which is four years in length. This study demonstrates that the case of upgrading nurse education was a carefully planned event requiring the acceptance of groups within nursing and the government, and was not part of the occupation's natural evolution. Publicly, nursing leaders argued that the …  Read more

    1999 — Science et droits de l'homme : le soutien international à Sakharov, 1968-1989
    Abstract

    Science in the 1970s and 1980s has come to be linked closely to the unsettling matter of human rights and international accountability. Andrei Sakharov contributed to this development by relying very substantially on his colleagues in North America and Western Europe in his battles to free Soviet society. He understood---as they themselves sometimes did not---to what degree the prestige of the Soviet Union's own military-industrial complex depended not only on the West's concrete achievements in science and technology, but on the political positions its scientists adopted in the Cold War. Hence this particular study, the purpose of which is to …  Read more

    Experiments were conducted with littermate gilts maintained in stainless steel metabolism cages within environmentally controlled rooms and consuming a corn-soybean meal based diet. The objectives of these studies were to investigate the impact of different dietary levels of manganese (Mn) and/or stage of the reproductive cycle on mineral metabolism and more specifically Mn metabolism in primigravid gilts and rats. Nutritional status was assessed using conventional balance studies, the analyses of physiological fluids (urine, plasma, colostrum, milk), tissues of the dam and offspring, and by a radioisotope dilution-balance technique. Trace element retention in the first-litter gilt was not significantly altered by …  Read more

    2014 — Roles of protein tyrosine phosphatase PTP-PEST in innate immune cells
    Abstract

    PTP-PEST (protein tyrosine phosphatase - proline-, glutamic acid-, serine- and threonine-rich; also named PTPN12) is an intracellular protein tyrosine phosphatase highly expressed in non-immune and immune cells. PTP-PEST was previously reported to be a critical regulator of cytoskeletal reorganization, cell adhesion and migration in non-immune cells. Moreover, PTP-PEST has a role as tumor suppressor in several types of human solid tumors. Recently, the roles of PTP-PEST in immune cells have also been clarified, using a cell type-specific conditional PTP-PEST-deficient mouse. In T cells, PTP-PEST has an essential role in secondary T cell activation, inhibition of T cell anergy and induction …  Read more

    2020 — Optimization of a cross-reactivity-free proteomic platform toward neurological biomarker analysis
    Abstract

    Proteins are macromolecules that are essential to many biological processes, and the pivotal role of proteins as effectors in the cellular environment makes them central to understanding human disease. For example, some of the most common neurological diseases, including Alzheimer’s disease, Parkinson’s disease, and multiple sclerosis, are believed to be mediated by dysregulated and/or mutated proteins. As such, the measurement of proteins, and indeed the development of protein-based biomarkers, holds great promise for the diagnosis, monitoring, and treatment of neurological diseases. Unfortunately, current gold standard techniques for protein analysis, namely sandwich immunoassays (i.e. ELISA) and mass spectrometry, suffer from a …  Read more

    Previous work has explored the behaviour of the 1D degenerate heat equation with one- sided boundary as well as the parabolic Anderson model (PAM) in the case of coloured noise in time and space. In this thesis we marry the two approaches to study the 1D degenerate heat equation with one-sided boundary and stochastic potential term, which we refer to as the degenerate parabolic Anderson Model (DPAM). More precisely, we consider a diffusion problem with linearly decaying diffusion coefficient at the boundary, constant initial data, Dirichlet boundary conditions, and a stochastic potential function with locally integrable covariance. In our work, …  Read more
