description: The E2F family of transcription factors regulate cellular growth, death and differentiation, but their role in cardiac biology remains to be fully explored. We hypothesized that the balance of the E2F pathway would determine cardiac development and function. We provide evidence for this via modulation of the E2F6 repressor, in a transgenic (Tg) mouse model. Targeted expression of E2F6 in the heart led to dilated cardiomyopathy (DCM) and death. Microarray analysis revealed that E2F responsive pathways were activated in Tg mice. Furthermore, we found that E2F6 and YY1 (E2F-co-factor) were translocated to the nucleus in Tg mice, providing a potential mechanism for the observed transcriptional activation. We also observed a marked decrease of Connexin43 protein in the myocardium, and reduced atrial conductivity in Tg mice which may lead to reduced cardiac function. The data demonstrates a novel role for E2F pathway outside of cell cycle control in the heart.

description: IRF2BP2 is a corepressor of IRF2, a transcription factor involved in the immune response. IRF2BP2 is also a coactivator of the VGLL4/TEAD4 complex in muscle. Given its functional duality, we asked how IRF2BP2 deletion would affect mouse development and adult muscle regeneration. Most Irf2bp2-/- mice die prior to birth, those that survive develop lymphoma in adulthood. Microarray profiling of Irf2bp2 knockout liver, heart, and skeletal muscle revealed a shared program of upregulated genes involved in inflammation and immunity. The function of IRF2BP2 in adult skeletal muscle recovery from cardiotoxin-induced injury was evaluated. Compared to WT mice, mice with macrophage-specific ablation of IRF2BP2 (Irf2bp2flox/LysMCre) or muscle-specific ablation of Irf2bp2 (Irf2bp2flox/MckCre) mice showed increased inflammation and impaired muscle regeneration. Global deletion of Irf2bp2 in mice results predominantly in embryonic death or lymphoma in adults. Irf2bp2 suppresses genes that mediate inflammation in mouse liver, heart, and in skeletal muscle, where IRF2BP2 promotes regeneration.

Properties and Behaviours of Fuzzy Cellular Automata

fuzzy cellular automata

description: Cellular automata are systems of interconnected cells which are discrete in space, time and state. Cell states are updated synchronously according to a local rule which is dependent upon the current state of the given cell and those of its neighbours in a pre-defined neighbourhood. The local rule is common to all cells. Fuzzy cellular automata extend this notion to systems which are discrete in space and time but not state. In this thesis, we explore fuzzy cellular automata which are created from the extension of Boolean rules in disjunctive normal form to continuous functions. Motivated by recent results on the classification of these rules from empirical evidence, we set out first to show that fuzzy cellular automata can shed some light on classical cellular automata and then to prove that the observed results are mathematically correct. The main results of this thesis can be divided into two categories. We first investigate the links between fuzzy cellular automata and their Boolean counter-parts. We prove that number conservation is preserved by this transformation. We further show that Boolean additive cellular automata have a definable property in their fuzzy form which we call self-oscillation. We then give a probabilistic interpretation of fuzzy cellular automata and show that homogeneous asymptotic states are equivalent to mean field approximations of Boolean cellular automata. We then turn our attention the asymptotic behaviour of fuzzy cellular automata. In the second half of the thesis we investigate the observed behaviours of the fuzzy cellular automata derived from balanced Boolean rules. We show that the empirical results of asymptotic behaviour are correct. In fuzzy form, the balanced rules can be categorized as one of three types: weighted average rules, self-averaging rules, and local majority rules. Each type is analyzed in a variety of ways using a range of tools to explain their behaviours.

description: Au moment de sa création, en 1959, la Commission de la capitale nationale (CCN) a pour but d’intégrer les villes de Hull et d’Ottawa, cette union devant symboliser, plus largement, celle des deux peuples fondateurs du Canada. Or, ce projet a provoqué d’importants débats politiques à Hull au fil des années. En se voyant ainsi intégrée à la région de la capitale nationale (RCN), Hull perdait une partie de son autonomie. Cette thèse propose une étude de la CCN pendant la rénovation urbaine de l’Île de Hull des années 1960 et 1970 afin d’y cerner le rôle joué par le débat sur la question nationale. Il s’agit d’un élément moteur de l’action de la CCN. En fait, la question nationale se trouve à plusieurs niveaux de la problématique. Ce sujet peu exploré donne à cette recherche son originalité. En examinant les relations entre les acteurs de la revitalisation du centre-ville, soit la CCN, le conseil municipal de Hull, les regroupements citoyens et le gouvernement du Québec, la thèse opte pour une perspective à la fois politique, institutionnelle et sociale. Un jeu de pouvoir entre les paliers gouvernementaux prend place alors que Hull et Ottawa se disputent les investissements fédéraux. Les citoyens de l’Île de Hull s’engagent dans les assemblées citoyennes et y développent une conscience régionale qui tardait à s’affirmer.
Distributed Optical Fiber Vibration Sensor Based on Rayleigh Backscattering

description: This thesis includes studies of developing distributed optical fiber vibration sensor based on Rayleigh backscattering with broad frequency response range and high spatial resolution. Distributed vibration sensor based on all-polarization-maintaining configurations of the phase-sensitive optical time domain reflectometry (OTDR) is developed to achieve high frequency response and spatial resolution. Signal fading and noise induced by polarization change can be mitigated via polarization-maintaining components. Pencil-break event is tested as a vibration source and the layout of the sensing fiber part is designed for real applications. The spatial resolution is 1m and the maximum distance between sensing fiber and vibration event is 18cm. Wavelet denoising method is introduced to improve the performance of the distributed vibration sensor based on phase-sensitive OTDR in standard single-mode fiber. Noise can be reduced more effectively by thresholding the wavelet coefficient. Sub-meter spatial resolution is obtained with a detectable frequency up to 8 kHz. A new distributed vibration sensor based on time-division multiplexing (TDM) scheme is also studied. A special probe waveform including a narrow pules and a quasi-continuous wave can combine the conventional phase-sensitive OTDR system and polarization diversity scheme together in one single-mode fiber without crosstalk. Position and frequency of the vibration can be determined by these two detection systems consecutively in different time slots. Vibration event up to 0.6 MHz is detected with 1m spatial resolution along a 680m single-mode sensing fiber. Continuous wavelet transform (CWT) is investigated to study the non-stationary vibration events measured by our phase OTDR system. The CWT approach can access both frequency and time information of the vibration event simultaneously. Distributed vibration measurements of 500Hz and 500Hz to 1 kHz sweep events over 20 cm fiber length are demonstrated using a single-mode fiber. Optical frequency-domain reflectometry (OFDR) for vibration sensing is proposed for the first time. The local Rayleigh backscatter spectrum shift in time sequence could be used to determine dynamic strain information at a specific position of the vibrated state with respect to that of the non-vibrated state. Measurable frequency range of 0-32 Hz with the spatial resolution of 10 cm is demonstrated along a 17 m fiber.

Towards enhanced resilience in city design: a proposition
Creators: name: Roggema, Rob
Publisher: name: Swinburne
Year: 2024

description: When we use the urban metabolism model for urban development, the input in the model is often valuable landscape, being the resource of the development, and output in the form of urban sprawl, as a result of city transformations. The resilience of these 'output' areas is low. The lack of resilience is mainly caused by the inflexibility in these areas where existing buildings, infrastructure, and public space cannot be moved when deemed necessary. In this article, a new vision for the city is proposed in which the locations of these objects are flexible and, as a result, the resilience is higher: a Dismantable City. Currently, the development of this sort of city is constrained by technical, social, and regulatory practice. However, the perspective of a Dismantable City is worthwhile because it is able to deal with sudden, surprising, and unprecedented climate impacts. Through self-organizing processes the city becomes adjustable and its objects mobile. This allows the city to configure itself according to environmental demands. The city is then able to withstand or even anticipate floods, heat waves, droughts, or bushfires. Adjustability can be found in several directions: creating multiple layers for urban activities (multi-layer urbanism), easing the way objects are constructed (light urbanism), or re-using abandoned spaces (transformable urbanism).

description: Background: Asthma is a chronic respiratory disease characterized by reversible bronchoconstriction and airway inflammation. According to Statistics Canada in 2014, 8.1% of Canadians aged 12 and older reported having asthma diagnosed by a health care professional. Therefore, in 2014 there were an estimated 274,661 persons with asthma in Alberta. Most epidemiological studies estimate prevalence and incidence using survey-based data, which has limitations. The Ontario Asthma Surveillance Information System (OASIS) group has developed and validated an algorithm for epidemiologic asthma studies using provincial health databases. In Alberta, there are some studies using provincial databases, but most are restricted to emergency department visits and do not represent the entire asthma population. Using the validated asthma definition for epidemiologic studies, we performed an analysis of the Alberta Health administrative databases to investigate and report province-wide asthma prevalence, incidence and mortality in Alberta from 1995 to 2015. Methods: Data from administrative databases, provided by Alberta Health, was analyzed to determine age and sex specific prevalence, incidence and mortality of the asthma population. The population cohort was all individuals residing in the province of Alberta, ages 0 to 99 from 1995–2015. Kendall’s Tau coefficient test was used to ascertain whether the observed trends were statistically significant. Results: Between 1995 and 2015, the age-standardized incidence of asthma decreased by more than 50% in both males and females. Prevalence, however, increased threefold over the 20 years (for both genders) from 3.9 to 12.3% (Tau = 1.00, p < 0.0001) in females and from 3.5 to 11.6% (Tau = 1.00, p < 0.0001) in males. Thus, in 2015 there were 496,927 people with asthma in Alberta. All-cause mortality in the asthma population decreased over time, in both females (Tau = − 0.71, p < 0.0001) and males (Tau = − 0.69, p = 0.0001). For the last several years, all-cause mortality was higher in those with asthma. There were ~ 7 deaths/1000 in the population with asthma versus ~ 5 deaths/1000 in those without asthma. Conclusions: The incidence of asthma decreased in both females and males while prevalence continued to increase, although at a slower rate than previously. All-cause mortality in asthma patients was higher than in those without asthma, but both decreased over time.

Médias et stéréotypes sociaux : Représentations de l’otaku japonais

description: Au Japon, le terme otaku désigne toute personne ayant un intérêt prononcé pour les produits de la culture populaire, en particulier les médias de divertissement comme la bande dessinée, le dessin animé, les jeux vidéo et leurs produits dérivés (figurines, modèles, costumes, etc.). Absorbé par son loisir et censément incapable de distinguer la réalité de la fiction, l’otaku est vu comme un sujet improductif et socialement inadapté voire dangereux. Cette étude a pour objectif de cerner les composantes du stéréotype façonné par le discours de presse et de les confronter aux représentations qu’en donne le milieu otaku à partir du film Otaku no Video (1992) explicitement réalisé pour rectifier cette image. Le film est composé de deux volets dialogiquement imbriqués l’un dans l’autre : d’une part, un dessin animé relatant le parcours d’un jeune Japonais qui devient otaku, récit initiatique fondé sur le vécu personnel et professionnel de ses auteurs; d’autre part, une série de dix « portraits » d’otaku sous forme d’entrevues en prises de vues réelles mais fictives. Le premier chapitre de l’étude explore l’origine et les formes de l’« étiquetage » (Becker, Kam) ainsi que les fondements de l’ostracisme qui frappe les otaku à cause de leur attrait pour l’« imaginaire » aux dépens du « fonctionnalisme institutionnel » (Castoriadis), ce par quoi on peut les considérer comme sujets postmodernes, producteurs et consommateurs de « simulacres » (Baudrillard, Azuma). Consacré au volet animé, le deuxième chapitre analyse les procédés narratifs utilisés pour déconstruire les représentations publiques stéréotypées et interroge les enjeux de ce contre-discours : que signifie la confrontation de deux figures masculines dont celle de l’otaku opposée à l’idéal japonais de l’homme productif et dévoué au bien commun? Le troisième chapitre cherche à éclairer le paradoxe des entrevues qui jouent avec humour sur la désinformation propagée dans la presse tout en expliquant les aspects inconnus ou moins connus de l’otakisme, phénomène aujourd’hui transnational et positivement connoté hors de son milieu d’origine.

description: In patients with diabetes, hyperglycemia leads to functional impairment of endothelial cells (ECs) and microangiopathy. Inflammation and endothelial dysfunction (ED) have been associated with the development of several cardiovascular complications. Concentration of methylglyoxal (MG) - a highly reactive aldehyde is increased in diabetes. In a non-pathological state, MG is detoxified by the enzymes glyoxalase-1 (GLO1) and glyoxalase 2 in presence of glutathione. This thesis examines the role of MG accumulation in ECs and bone marrow cells (BMCs), with the consequences it has for their function. To this end, a transgenic mouse model was used in which the human enzyme GLO1 is overexpressed in the vasculature By using a GLO1 overexpressing mouse model studies described here examined the contribution of MG-induced inflammation in vivo to cardiovascular complications of diabetes, namely diabetic heart failure and peripheral vascular disease. This study confirmed that accumulation of MG leads to inflammation and cell death, and further explained how MG affects the role of ECs in development of the heart failure and BMCs in the revascularization. Overexpression of GLO1 in the vasculature diminished MG-induced inflammation, reduced EC death and delayed and limited the loss of cardiac function in streptozotocin (STZ)-induced diabetic mice (Chapter 2). The in vitro part of this study showed that MG and tumor necrosis factor (TNF- have a synergistic effect on cell death (Chapter 3). Overexpressing the GLO1 in BMCs only, restored neovascularization in ischaemic tissue of mice with STZ-induced diabetes (Chapter 4). Taken together, the results of this thesis suggest that hyperglycemia increased MG leads to endothelial inflammation, EC death and decreased angiogenic potential of BMCs. Furthermore, this MG-induced inflammation and reduced cell function observed, identifies a potential target for therapy of the cardiovascular complications seen in diabetes.

description: In 2020, the European Commission has announced to propose a Sustainable Product Policy for the EU which shall ensure that the performance of front-runners in sustainability progressively becomes the norm. In addition, the European Commission has re-emphasised the necessity to significantly improve the effectiveness of the current Ecodesign framework for energy-related products. With this paper, we present an initial outline of a policy approach which we call the "EU front-runner approach". The approach aims at installing a regulatory framework which enables a semi-automated, progressive adaptation of ecodesign minimum requirements for products. It builds on performance levels of the best products available on the market by aggregating information in a database. The "front-runner approach" could first be applied to progressively adapt product-related minimum energy-efficiency requirements. This way it would serve as a starting point to introduce this concept to the EU policy arena. While the approach can be applied for energy efficiency, it is neither limited to energy-related products nor to energy-related requirements. It can be applied to the wide range of non-energy related products within the scope of the upcoming Ecodesign for Sustainable Products Regulation (ESPR) as well as to non-energy-related requirements, such as minimum requirements for durability, reparability, recyclability and recycled content.

Or, il semble qu’une ambiguïté théorique entoure la «mise à distance» ou la «prégnance» de telles pratiques et des discours qui les étayent. Fait-on face à un phénomène en phase de s’effacer ou de s’accélérer? Il appert en fin d’analyse que les polymorphismes des dispositions assimilationnistes se présentent de manière diffuse à l’intérieur des espaces sociaux canadiens et qu’ils s’inscrivent dans un récit global «colonial d’établissement» généralement fondé sur un horizon normatif libéral. Nous proposons ici «d’extraire» les composantes d’un «discours assimilationniste manifeste» afin de mettre en relief certains procédés discursifs d’importance majeure qui participent au façonnement de la relation entre l’État, les corps sociaux coloniaux d’établissement et les peuples autochtones au Canada.

description: Predator-prey interactions in natural ecosystems generate complex food webs that have a simple universal body-size architecture where predators are systematically larger than their prey. Food-web theory shows that the highest predator-prey body-mass ratios found in natural food webs may be especially important because they create weak interactions with slow dynamics that stabilize communities against perturbations and maintain ecosystem functioning. Identifying these vital interactions in real communities typically requires arduous identification of interactions in complex food webs. Here, we overcome this obstacle by developing predator-trait models to predict average body-mass ratios based on a database comprising 290 food webs from freshwater, marine and terrestrial ecosystems across all continents. We analysed how species traits constrain body-size architecture by changing the slope of the predator-prey body-mass scaling. Across ecosystems, we found high body-mass ratios for predator groups with specific trait combinations including (1) small vertebrates and (2) large swimming or flying predators. Including the metabolic and movement types of predators increased the accuracy of predicting which species are engaged in high body-mass ratio interactions. We demonstrate that species traits explain striking patterns in the body-size architecture of natural food webs that underpin the stability and functioning of ecosystems, paving the way for community-level management of the most complex natural ecosystems.

description: NiOx films on Si(111) were put in contact with oxygen at elevated temperatures. During heating and cooling in oxygen atmosphere Near Ambient Pressure (NAP)-XPS and -XAS and work function (WF) measurements reveal the creation and replenishing of oxygen vacancies in dependence of temperature. Oxygen vacancies manifest themselves as a distinct O1s feature at 528.9 eV on the low binding energy side of the main NiO peak as well as by a distinct deviation of the Ni2p3/2 spectral features from the typical NiO spectra. DFT calculations reveal that the presence of oxygen vacancies leads to a charge redistribution and altered bond lengths of the atoms surrounding the vacancies causing the observed spectral changes. Furthermore, we observed that a broadening of the lowest energy peak in the O K-edge spectra can be attributed to oxygen vacancies. In the presence of oxygen vacancies, the WF is lowered by 0.1 eV. © 2023 The Authors

description: Optimisation involves finding the best solution to an unsolved problem. In problems that change over time, studies have shown that the problem's behaviour fundamentally affects the performance of the optimisation technique. Therefore, determining the behaviour of an unknown dynamic problem would allow the chosen approach to be tailored accordingly and improve the overall optimisation procedure. This thesis proposes a set of characterisation metrics that gather information on the behaviour of a dynamic problem. These metrics can successfully characterise a wide range of problems based on their behaviour and their topology, allowing for fast and efficient bottom-up characterisation of dynamic problems.

description: The bony fin rays of the zebrafish caudal fin are a convenient system for studying bone morphogenesis and patterning. Joints and bifurcations in fin rays follow predictable spatial patterns, though the mechanisms underlying these patterns are not well understood. We developed simulation models to explore ray pattern formation mechanisms in growing fins. In all models, the fin ray growth rates are based on quantitative experimental data. The different models simulate ray joint formation and bifurcation formation using different hypothetical mechanisms. In the most plausible model, ray joint and bifurcation formation result from the accumulation of two substances, arbitrarily named J and B. Model parameters were optimized to find the best fit between model output and quantitative experimental data on fin ray patterns. The model will be tested in the future by evaluating how well it can predict fin ray patterns in different fin shapes, mutant zebrafish fins, and other fish species.

description: Information on properties of ocean waves, such as wave height, period, direction and others, is important for design of marine and coastal structures, for other engineering and safety issues. One of the most important issues in this regard is related to extreme wave events. In the thesis we presented analysis of long-term wave simulations performed using a numerical scheme based on solving three-dimensional potential equations in deep water. A set of features and statistics are investigated. The emergence of coherent structures on the ocean surface, closely related to the tendency of high waves to occur in groups, is analysed.

description: In this article we introduce the unique categories of conservation areas that are only present in a single country. These territories were established between 1900 and 2003, and have also undergone IUCN classification, and are thus legitimate categories. We present these classifications with their locations, and also consider, whether these were well thought out, or unnecessary. We take a look at their spread among the official IUCN categories, paired with the size of the territories. Moreover, we study their countries of origin, which shows that even though every continent has such areas, their spread is not even. Lastly, we select five of such places and characterize them, to shed light on the reasons behind the unique classifications.
Whiteness and policing Vietnamese Australian communities

description: The empirical study explores the effects of whiteness on relations between a predominantly white police force and Vietnamese Australian communities. The study draws on fifty-four interviews with white police officers, ten focus groups with Vietnamese Australian community members and nineteen interviews with Vietnamese Australian social justice workers. The approach links historical constructions of whiteness to the current practices of the state police force and examines the racialisation of communities and other exclusions. The study finds material effects of structural whiteness for Vietnamese Australian communities including reduced access to police services, racialised hierarchies of criminalisation and a sense of not belonging.

description: La thèse étudie les modalités de coexistence entre les deux dénominations religieuses présentes dans la ville de Castres, située dans l’ancienne province du Haut-Languedoc. L’étude démontre que les conditions d’existence des réformés français se sont généralement stabilisées au cours de la période comprise entre 1629 et 1661. L’analyse des édits royaux et de la correspondance d’hommes politiques près du régime ont permis d’établir quelles étaient ces nouvelles conditions et d’exposer la mise en place d’une dynamique de clémence et de resserrement soumis aux aléas de la politique extérieure et intérieure de l’époque. Ces conditions étant établies, l’étude s’est penchée sur la nature des interactions religieuses qui constituaient l’essence même de cette coexistence. Après un portrait de la ville de Castres et de la société qui la composait, l’analyse a porté sur les composantes de la localité qui sont révélatrices d’une coexistence pacifique et fonctionnelle : la Chambre de l’Édit, le consulat urbain, le collège et l’Académie. C’est à l’intérieur de ces cadres que nous avons qualifiés d’environnements interconfessionnels que les Castrais interagissaient pour maintenir leur modus vivendi stable, paisible et fonctionnel. Les conflits n’étaient toutefois pas absents et, aux vues de cas qui exacerbèrent les tensions, l’analyse a démontré, grâce à la consultation de diverses sources, la constitution de frontières confessionnelles qui séparaient les deux communautés religieuses. Ces frontières, mobiles et changeantes, ont évolué graduellement pour devenir de plus en plus prononcées. À terme, l’analyse de ces lieux de socialisation et des diverses frontières confessionnelles a démontré la coopération entre les membres des confessions adverses et, ultimement, le choix d’une société qui privilégia l’édilité, le communautaire, l’éducation, le professionnel, et parfois les relations interpersonnelles, avant le religieux.

description: People who use drugs (PWUD) face concurrent public health emergencies from overdoses, HIV, hepatitis C, and COVID-19, leading to an unprecedented syndemic. Responses such as decriminalization and providing a safe supply of pharmaceutical-grade drugs, that goes beyond treatment, to PWUD could reduce impacts of this syndemic. Solutions already implemented for COVID-19, such as emergency safe supply prescribing and providing housing to people experiencing homelessness, must be sustained once COVID-19 is contained. This pandemic is a catastrophe, but is also a chance to develop and maintain equitable and sustainable solutions to the harms associated with the criminalization of drug use.

description: This thesis report works on optically characterizing waveguide based biosensors consisting of thin, narrow Au stripes embedded in CYTOP. The devices were examined using an ever evolving and improving interrogation setup, variations of which are described in detail in this document. A number of changes were made to the setup configuration in order to reduce noise levels and increase efficiency and accuracy of acquired measurements. Waveguides of varying configurations (straight waveguides and Mach-Zehnder Interferometers with etched and cladded channels) are described and optically characterized. The characterization results of these devices are presented in this thesis. Bulk index measurements are carried out in order to determine a suitable bio-sensing solution with a refractive index matched to that of CYTOP. Step index measurements clearly distinguishing the introduction of sensing solutions of refractive indices varying from one another, are made available. Preliminary bio-sensing experiments involving detection of change in refractive index of sensing fluid as well as adlayer thickness with the introduction of analytes binding to the waveguide surface that has been functionalized with antibodies, using both straight and cladded waveguides with single mode outputs are studied.

description: Das Ziel des Vorhabens bestand darin, belastbare Aussagen zu den Potenzialen des Radverkehrs in Bezug auf Umweltentlastungswirkungen zu gewinnen. Mit Hilfe eines für das Projekt entwickelten Kennwertmodells wurden Stellschrauben analysiert und variiert, um dadurch Veränderungen von Fahrleistungen und Umweltwirkungen abzuschätzen. Im Ergebnis bringt die Verlagerung kurzer Kfz-Wege bis fünf Kilometer Länge nur eine geringe Änderung der CO2-Emissionen von ein bis drei Prozent, da der Anteil dieser Wege an der ⁠Fahrleistung⁠ niedrig ist. Würde das Fahrrad auch für die von der Bevölkerung als „gut mit dem Fahrrad erreichbar“ wahrgenommenen (weiter entfernten) Ziele genutzt, steigt das Reduktionspotenzial deutlich auf sechs bis elf Prozent der gesamten CO2-Emissionen des werktäglichen Personenverkehrs. Werden neben der reinen Verlagerung auch Strategien der Verkehrsvermeidung in die Modellrechnungen integriert sind Fahrleistungsrückgänge von 19 bis 38 Prozent bzw. eine CO2-Minderung von 13 bis 27 Prozent errechnet worden. Die Ergebnisse lassen damit Schlussfolgerungen über die Potenziale des Radverkehrs zur Emissionsreduzierung zu und geben Hinweise zu deren Einordnung in ganzheitliche nachhaltige Strategien. Dadurch wird deutlich, welchen Beitrag die Verlagerung von Verkehrsmittelanteilen (Modal Shift) vom motorisierten Individualverkehr (MIV) sowie die Vermeidung von weiten MIV-Wegen leisten kann.
Unified collision avoidance behaviour for autonomously steering characters
Creators: name: Pace, Shannon
Publisher: name: Swinburne

description: In the field of interactive multimedia, digital characters are often required to autonomously perform specific forms of motion such as wandering and pursuing. In contemporary multimedia systems, multiple collision avoidance algorithms are simultaneously employed in an attempt to prevent characters from colliding with obstacles within their simulated environment. These algorithms compete for control over character motion, whichcan produce erratic trajectories and suboptimal collision avoidance behaviour. This thesis presents a technique for dynamically generating a unified representation of the steering problem, enabling characters to avoid obstacles in a manner complementary to their intended forms of motion.
5-and 6-Membered Hydrazides as Potential Catalysts for Diels-Alder Cycloadditions

description: Part A: Synthesis of 5- and 6-Membered Camphor-Based Hydrazides as Organocatalysts for Cycloaddition Reactions The favorable environmental and reactivity qualities of organocatalysts are contributing to the popularization of this method for the acceleration of enantioselective reactions. Research in our group has been focused on the synthesis of camphor-derived hydrazide based organocatalysts for enantioselective cycloaddition processes. Recent results suggest that the presence of an exocyclic electron withdrawing group on the hydrazide moiety, as well as the incorporation of the hydrazide moiety into a 6-membered ring, may have a beneficial effect on the kinetics of the catalysts. A variety of camphor-based cyclic hydrazides have been synthesized and tested in Diels-Alder reactions, varying both the ring size and placement of the electron withdrawing group. Part B: Synthesis of Isocampholenic Acids by the Rearrangement of Camphor Derivatives A variety of substituted isocampholenic acid derivatives have been prepared by rearrangement of the camphor skeleton of a variety of tertiary alcohols derived from ketopinic acid. The reaction is highly reliable and retains the stereochemical information from the camphor scaffold. This rearrangement represents an efficient way to prepare synthetically useful isocampholenic acids. Mechanistic experiments show that the rearrangement does not involve exogenous water and that a short-lived carbocation is implicated in the reaction. Part C: Diastereoselective Formation of Quaternary Centers from Stereodefined Trisubstituted Alkenes Previous work in our laboratory has focused on the preparation of single-isomer tri- and tetra-substituted olefins. This methodology has been used in the construction of a variety of alkenyl esters in good to excellent yields. These alkenyl esters could then be transformed into the corresponding 3,3-disubstituted allyl boronates in a stereocontrolled fashion. There are a limited number of methods available to prepare single isomer 3,3-disubstituted allyl boronates, which can be important precursors in the stereoselective preparation of all-carbon quaternary centers. Our methodology has therefore been applied to the construction of single isomer 3,3-disubstituted allyl boronates and subsequently used in the stereoselective generation of all-carbon quaternary centers by the reaction of these allyl boronates with aldehydes.
Au-delà de la « mésentente » : La politique chez Jacques Rancière et Hannah Arendt

description: Cette thèse de maîtrise porte sur les pensées politiques de Jacques Rancière et d’Hannah Arendt. Elle a pour point de départ la critique formulée par Rancière à l’endroit d’Arendt. Dans un premier temps, nous allons explorer les diverses accusations formulées par Rancière à l’endroit de la penseuse et, dans un deuxième temps, il sera question de répondre à ces accusations en soulignant les importantes affinités qui existent entre leurs conceptions du conflit et de la théâtralité en politique. Nous constaterons en outre que le projet arendtien visant à réhabiliter la dignité de la politique ne se nourrit pas principalement de ses lectures d’Aristote, contrairement à ce que suggère Rancière, mais bien de ses lectures de Machiavel. C’est précisément à partir du machiavélisme que nous allons proposer un rapprochement entre Arendt et Rancière et ainsi, aller au-delà de leur mésentente.
Development and Application of a Virtual Reality Stumble Method to Test an Angular Velocity Control Orthosis

description: The Ottawalk-Speed (OWS) orthosis prevents knee collapse in stumble situations. The purpose of this study was to develop a virtual stumble perturbation to measure OWS response to a knee collapse when walking. A new split speed perturbation was developed for the CAREN virtual reality system. This perturbation induced a stumble with increased knee flexion for five able-bodied participants, with either a hopping or stopping recovery strategy. Three knee-ankle-foot orthosis users were subjected to five stumble trials while wearing the OWS. OWS participants used a straight-legged recovery strategy, and extended the knee through recovery weight acceptance. Therefore, the split speed perturbation was not appropriate to measure OWS response to a stumble since knee collapse did not occur. The OWS allowed free knee motion during gait. Further study is required to measure OWS response during a stumble with a knee collapse event.
Religious Devotions in the Southern Low Countries as an Opposition to Catharism 1150-1300

Religious Devotions

description: Through contemplation, and the practice of actions with religious meaning, faith is taught and reinforced. Beliefs that conflict with the established teaching of a religious group are sometimes ruled by it as heretical. Effective in countering heresy are religious practices that would not be performed by those deemed heretical. The practices indicate those who are orthodox and safeguard them from accusations of heresy. Catharism was an expanding heretical sect in the twelfth and thirteenth centuries, enticing adherents away from the Roman Catholic Church, rejecting the Catholic sacraments and holding to a dualistic theology. Through the study of eleven hagiographies (idealized biographies of saints) this thesis identifies and examines sixteen attributes of people who lived in the southern Low Countries, corresponding with contemporary Belgium and northeastern France. We show how these attributes aided the Catholic Church’s struggle against Catharism through the confirmation, dissemination, and distinction of orthodoxy, while serving to nullify heterodox suspicion of the hagiographical subjects.
Uncertainty reasoning in Prolog with layered meta-interpreters

description: The authors propose an architecture for uncertainty reasoning for rule-based systems in Prolog. Previous work has assumed predefined calculus for the propagation of uncertainty restricted to a single line of reasoning or where no negation is allowed. The authors identify the issues that need to be considered for both handling negation and taking a more global view. The authors adopt a pragmatic approach and argue that reasoning with uncertainty can be achieved by a flexible meta-architecture that is suitable for describing and reasoning with different representations of uncertainties, combining multiple lines of reasoning and reasoning with unknowns and negation. The authors show that a layered meta-interpreter is a good flexible architecture that can accommodate different sets of assumptions for incorporating uncertainty in rule-based systems in Prolog.
