description: La recherche sur la depression chez les adolescents est encore largement influencee par des modeles de depression adulte (Baron, 1993; Cicchetti, Rogosch et Toth, 1994; Lewinsohn et al., 1994; Reynolds et Johnston, 1994). Cette orientation neglige cependant l'impact de caracteristiques developpementales propres a l'adolescence. La perspective developpementale permet precisement de tenir compte de telles caracteristiques (Cicchetti et al., 1994). Damon (1983) a identifie cinq taches developpementales qui definissent la dimension psychosociale de l'adolescence: l'amitie, la sexualite, la separation-individuation, la pensee socio-politique et l'identite/concept de soi. Dans le contexte de la psychopathologie developpementale, nous avons postule un modele structural tripartite reliant ces taches developpementales a la symptomatologie depressive. L'objectif principal de cette these est donc d'examiner les relations entre les taches developpementales proposees par Damon (1983) et la symptomatologie depressive. D'une part, nous posons l'hypothese que l'amitie, la sexualite, la separation-individuation et la pensee socio-politique, influencent significativement le concept de soi, lequel influence aussi de facon significative la symptomatologie depressive. D'autre part, nous posons une seconde hypothese selon laquelle ces memes relations devraient etre systematiquement plus elevees chez les adolescents plus ages que chez les plus jeunes. Afin de verifier ces hypotheses, 413 adolescents non cliniques ages entre 13 et 19 ans et provenant de milieux scolaires ont repondu a un questionnaire forme d'echelles visant a mesurer ces variables developpementales et la symptomatologie depressive. Les analyses statistiques ont ete effectuees a l'aide du logiciel LISREL VII (Joreskog et Sorbom, 1989). Les resultats obtenus supportent dans l'ensemble les deux hypotheses postulees. Non seulement les cinq taches developpementales identifiees ont un effet significatif sur la symptomatologie depressive, mais ces relations apparaissent systematiquement plus elevees chez les adolescents plus ages.

description: Cette these porte sur un type d'illegalismes qui, malgre son analogie frappante avec les situations conflictuelles saisies exclusivement par l'appareil penal, profite d'un reseau d'appareils de controle etendu et de modes de reglement de conflits varies, soit les atteintes contre l'environnement. En effet, lors d'atteintes contre l'environnement, il est souvent question d'importants dommages pecuniaires et d'atteintes a la vie. Pourtant, contrairement aux illegalismes traditionnels qui sont exclusivement referes au penal, les atteintes contre l'environnement sont pluridimensionnelles, c'est-a-dire qu'elles peuvent etre apprehendees a la lumiere des champs normatifs penal, civil et administratif. Ainsi, les atteintes contre l'environnement peuvent faire l'objet d'un large eventail de modes de reglement de conflits tels des ententes a l'amiable, des avertissements, des amendes statutaires, des peines d'emprisonnement, etc.. Notre recherche, de type qualitatif, a pour objet d'etude l'anlyse du processus de mise en application des lois et reglements en matiere environnementale au Quebec. Vu les particularites de ce type d'illegalisme, nous avons aborde les atteintes contre l'environnement, dans cette these, non pas comme des crimes au meme titre que les autres illegalismes, mais comme des illegalismes privilegies, tels que definit par Acosta (1988). Le concept d'illegalisme privilegie nous a procure une approche globale qui nous a permis d'apprecier la multiplicite des formes de reglement de conflits et la complexite des rapports qui s'etablissent entre les divers champs normatifs en presence dans les cas d'atteintes a l'environnement.

description: After over three decades of unsuccessful attempts, we report the first detection of molecular gas emission in Malin 1, the largest spiral galaxy observed to date, and one of the most iconic giant low surface brightness galaxies. Using ALMA, we detect significant $^{12}$CO(J=1-0) emission in the galaxy's central region and tentatively identify CO emission across three regions on the disc. These observations allow for a better estimate of the H$_2$ mass and molecular gas mass surface density, both of which are remarkably low given the galaxy's scale. By integrating data on its HI mass, we derive a very low molecular-to-atomic gas mass ratio. Overall, our results highlight the minimal presence of molecular gas in Malin 1, contrasting sharply with its extensive, homogeneous atomic gas reservoir. For the first time, we position Malin 1 on the Kennicutt-Schmidt (K-S) diagram, where it falls below the main sequence for normal spirals, consistent with previous upper limits but now with more accurate figures. These findings are crucial for constraining our understanding of star formation processes in environments characterized by extremely low molecular gas densities and for refining models of galaxy formation, thereby improving predictions concerning the formation, evolution, and distribution of these giant, elusive galaxies.

But if the aim is to emulate the American president-elect, The Cory begins with some massive drawbacks.
Adding probability to neural network prediction of NICU mortality

Year: 2006
Subjects: subject: Engineering, System Science.

description: It has been shown that neural networks can be trained to predict clinical outcomes of a neonatal intensive care unit (NICU). This thesis expands past research and presents a neural network approach that predicts the probability of NICU mortality. The resulting neural network models are able to not only classify the dichotomous outcome (i.e. survival or death) but also estimate the probability of death. The general conditions necessary for the neural network to estimate probabilities are discussed in the thesis. The neural network estimation of mortality probability includes the following steps: modeling the neural network cost function with the likelihood function; deriving the gradient ascent training algorithm to perform the maximum likelihood estimation; developing the neural network models with the NICU data; evaluating performance by the Receiver Operating Characteristic Curve and Hosmer-Lemeshow test. These neural network based probability estimation models applied as the mortality prognostic tools are presented. For this purpose, two approaches for improving the models' sensitivity are suggested: adjustment of the cost function and the cutoff point. Both of them were tested and results are discussed.
External Influences on Southern African Transformations: ‘1989’ in Perspective
Creators: name: Saunders, Chris
Publisher: name: Leipziger Universitätsverlag
Year: 2019

description: The changes in Southern Africa that began during the 1980s were due to a specific interaction of internal and external factors. However, this interplay must be placed in a historical perspective, because it goes back to the early 1960s, when decolonisation took hold of large parts of the continent, but also encountered coordinated resistance of the hitherto ruling powers in southern Africa, which led to a long social and military conflict that, like the Cold War in general, first weakened and then came to an end. The external shock of the revolutions in Eastern Europe brought the revolution in Africa, which had begun in 1960, to a successful end. The direct effect could be seen in South Africa, where the de Klerk government abandoned its fear of a Soviet-backed Communist takeover, while the ANC opened up to the prospect of a mixed and globally networked economy. The other states of southern Africa followed the general trend towards liberal democratic constitutions and elections to a very different degree, and the regional integration process initiated with the founding of SADC remains fragile. Nevertheless, in the end it can be concluded that the upheaval of 1989 was far more significant for the region than the subsequent caesura of 9/11 or the financial crisis of 2008–2010.

A PCA-based approach to the three-dimensional reconstruction of human body from single frontal-view silhouette
Creators: name: Xi, Pengcheng
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2007
Subjects: subject: Computer Science.

description: We introduce a data-driven approach to build a human body model from a single photograph by performing Principal Components Analysis (PCA) on a database of body segments. Our work consists of two main parts, first consistent parameterization of the Civilian American and European Surface Anthropometry Resources (CAESAR) database and second segmented reconstructions of 3D bodies out of 2D photographs. Analysis on a dataset of 3D scanned surfaces has presented problems because of incompleteness on the surfaces and because of variances in shape, size and pose. In this thesis, a high-resolution generic model is aligned to data in the CAESAR database in order to obtain a consistent parameterization. A Radial Basis Function (RBF) network is built for rough deformation by using landmark information from the generic model, anatomical landmarks provided by CAESAR dataset and virtual landmarks created automatically for geometric deformation. Fine mapping then successfully applies a weighted sum of errors on both surface data and the smoothness of deformation. Compared with conventional methods, our approach has a higher efficiency in making robust alignment. Principal components analyses on segmented bodies display a richer variation than that of the whole body. Our 3D reconstruction process is composed of training and testing processes. The training aims at finding a relationship between PCA spaces in 3D and 2D. Testing process then applies this relationship to the 2D PCA-space coordinate of a new image and calculates its coordinate in the 3D PCA-space. Building several PCAs for different body parts, then making separate reconstructions and merging reconstructed body parts create the final results. We prove from practical experiments that 3D segmented body reconstructions have superiority over whole-body reconstructions. We demonstrate our approach by constructing models of a Caucasian male, an Asian male and a toddler from corresponding photographs based on a Caucasian adult oriented database. Our numerical validation includes 3D reconstructions from silhouettes of Asian males and females, Caucasian males and females, and African males and females, for which we already have their real 3D body information available from the CAESAR database.

description: The pattern of nucleosynthesis during the explosion of a low-mass neutron star formed in a close binary system in the stripping scenario is considered. In the scenario considered the shock arising during the explosion is shown to strongly heat the expanding neutron star matter. The heavy nuclei produced at the preceding stage of nucleosynthesis are partially destroyed as a result of a sharp increase in the role of photonuclear reactions. It is shown that even short-term heating of the matter by the shock can exert a noticeable influence on the results of the synthesis of elements in the r-process in the inner crust matter, while explosive nucleosynthesis gives rise to new elements in the outer crust matter with mass numbers A from 50 to 130.

Subjects: subject: Biology, Physiology.

description: Aquatic ecosystems are continuously exposed to a variety of environmental toxicants including polychlorinated biphenyls (PCBs). A portion of the energy assimilated by the fish is dedicated to detoxification. This study investigates the changes in energetic demands associated with increased detoxification. Two CYP1A inducers were employed, PCB-126 and BNF. Resveratrol, a documented inhibitor of CYP1A activity and gene expression, was used to correlate metabolic changes in CYP1A induction with any metabolic changes. PCB-126 and BNF effectively induced CYP1A activity in vitro and in vivo. Energy metabolism was measured as changes in oxygen consumption rates and changes in plasma glucose and triglyceride concentrations as well as liver glycogen. PCB-126 and BNF treatments resulted in significant changes in metabolic parameters. Treatments with RVT were inconclusive. Although results from this study imply possible energetic changes associated with exposure, further investigation is required to obtain more conclusive results on energetic costs of exposure and detoxification.
Design of Josephson diode based on magnetic impurity

description: We theoretically propose a mechanism to realize the superconducting diode effect (SDE): The current can generate a magnetic field, affecting the magnetic moment of magnetic impurity. When the connection region of the Josephson junction is coupled with the magnetic impurity, the supercurrents in positive and negative directions have different influences on the magnetic moment. This results in a phenomenon that the critical supercurrents in these opposite directions are unequal, which is called SDE. We model the Josephson connection region by a quantum dot. Then the critical supercurrents are investigated by the non-equilibrium Green's function method, and we carry out a detailed symmetry analysis on the supercurrent relations. The calculation results confirm that the SDE does exist in this system. Besides, the SDE is significant in a wide parameter space and can be effectively adjusted in various ways. Our design only demands a magnetic impurity and conventional superconductors. The unconventional finite-momentum Cooper pair and spin-orbit coupling are not required, and there is also no need for the existence of chirality or an external magnetic field. Our work provides a universal device structure for the development of superconducting electronics.

description: The Coastal Community Development Project (CCDP), implemented between 2013 and 2017, was designed to reduce poverty and achieve sustainable economic growth in 12 coastal districts of Indonesia. The project took a comprehensive approach, combining sustainable marine and coastal natural resource management with economic and livelihood development in coastal and small island communities where poverty was endemic. It invested in fisheries, aquaculture, and related marketing and support structures. Project participants were provided with fishing gear and motorized engines for their fishing boats, enabling them to fish further from the coast, and thus catch a more diverse array of higher-value fish. They were linked to profitable markets, and fish processing groups were established that primarily enabled local women to process and market fish. Infrastructure groups were created to construct village information centers, fish smokehouses, processing warehouses and marketplaces. Additionally, the project provided cooler boxes to store fresh fish and reduce post-harvest losses. It also offered support for food-safety certification. Steps were taken to improve the governance and management of marine resources, including through village-based integrated coastal management plans and the designation of marine protection areas. An impact assessment of CCDP was conducted in 2018. The assessment used a mixed-methods approach that combined quantitative household-level and community-level surveys and a qualitative survey (focus groups discussions and key informant interviews).

description: Breast cancer has changed in recent years from a terminal condition to a chronic disease, which can significantly impact a couple's relationship and overall adjustment. The first objective was to survey the shared and reciprocally determined adjustment processes which unfold within couples who face breast cancer. Attachment theory was then used as the grounding framework to both understand interpersonal dynamics and to provide a rationale for offering empirically-supported Emotionally Focused Therapy (EFT) to couples experiencing unremitting psychological and relational distress following diagnosis and treatment for breast cancer. The second objective involved evaluating the clinical efficacy of EFT on couples' psychological adjustment and patients' Natural Killer Cell Cytotoxicity (NKCC)---an important immune parameter implicated in control of metastatic disease. Twelve couples were randomized to receive either twenty sessions of EFT or Psycho-education (PE). A multiple baseline experimental design across couples was used. Results indicated that, compared to couples randomized to PE, those who received EFT evidenced more variation on outcome variables following EFT. Specifically, more than 50% of couples who received EFT evidenced clinically significant improvement in dyadic adjustment, and quality of life, as well as attenuation in mood disturbance and trauma symptoms. Women randomized to EFT evidenced more variation in response to treatment, with half of the sample experiencing small, but clinically irrelevant up regulation, in NKCC, while the other half showed clinically significant down-regulation in NKCC. Women receiving PE showed no changes in NKCC. More importantly, shifts in NKCC were in keeping with trajectories in dyadic adjustment and clinical events unfolding during the course of treatment. Findings provided initial support for offering EFT to couples experiencing emotional and relational following diagnosis and treatment of early breast cancer. Changes observed in NKCC, though in keeping with established relationships with psychological distress, were more tentative in nature.

description: Achieving the EU's carbon-neutral target by 2050 requires a significant reduction in energy use within the building sector, which accounts for 40% of the total energy use. European historical cities, particularly heritage townhouses, pose a unique challenge due to their architectural and cultural value. The EU-Horizon project HeriTACE is addressing this challenge through a holistic renovation approach. This study investigates the impact of energy-conscious occupant behaviour on primary energy use for space heating in heritage townhouses in Ghent, Belgium. Three realities are compared: energy performance calculations, dynamic simulations, and actual energy use measurements. The energy performance calculations, based on the Belgian EPB software, tend to overestimate energy use by assuming a continuous heating system and a constant indoor temperature of 18°C. Dynamic simulations using Modelica incorporate actual occupancy behaviours and flexible heating patterns, leading to significantly lower energy use estimates. This actual heating patterns are derived from indoor temperature measurements in the case study buildings. Real energy use data, derived from energy bills, reveals that actual consumption can be up to seven times lower than EPB calculations. The findings suggest that dynamic simulations, which account for realistic occupant behaviours and lower comfort expectations, are more accurate in predicting energy use and are essential for developing effective renovation strategies for heritage townhouses.

description: Code metamorphism refers to a computer programming exercise wherein the program modifies its own code (partial or entire) consistently and automatically while retaining its core functionality. This technique is often used for online performance optimization and automated crash recovery in certain mission-critical applications. However, the technique has been misappropriated by malware creators to bypass signature-based detection measures instituted by anti-malware engines. However, current code mutation engines used by threat actors offer only a limited degree of mutation, which is frequently detectable via static code analysis. The advent of large language models (LLMs), such as ChatGPT 4.0 and Google Bard may lead to a significant evolution in this landscape. These models have demonstrated a level of algorithm comprehension and code synthesis capability that closely resembles human abilities. This advancement has sparked concerns among experts that such models could be exploited by threat actors to generate sophisticated metamorphic malware. This paper explores the potential of several prominent LLMs for software code mutation that may be used to reconstruct (with mutation) existing malware code bases or create new forms of embedded mutation engines for next-gen metamorphic malwares. In this work, we introduce a framework for creating self-testing program mutation engines based on LLM/Transformer-based models. The proposed framework serves as an essential tool in testing next-gen metamorphic malware detection engines.

description: Wire Arc Additive Manufacturing (WAAM) has emerged as a viable technique for fabricating high-performance components, especially with materials like titanium. One critical parameter influencing the process efficiency and quality is the stickout length. This study investigates the impact of varying the stickout on the energy input during WAAM of titanium. By increasing the stickout length, the Joule heating effect on the wire is augmented, which potentially reduces the required arc power for achieving consistent material deposition. The research examines how adjusting the stickout length affects the thermal input to the wire and the substrate, thereby enabling optimization of the energy distribution. The results indicate that with a greater stickout, it is possible to either decrease the arc power while maintaining the deposition rate or to modulate the energy imparted to the wire and the substrate. These findings provide insights into enhancing WAAM process efficiency and tailoring thermal profiles for improved material properties.

description: Astrometry from Gaia DR3 has produced a sample of $\sim$170,000 Keplerian orbital solutions, with many more anticipated in the next few years. These data have enormous potential to constrain the population of binary stars, giant planets, and compact objects in the Solar neighborhood. But in order to use the published orbit catalogs for statistical inference, it is necessary to understand their selection function: what is the probability that a binary with a given set of properties ends up in a catalog? We show that such a selection function for the Gaia DR3 astrometric binary catalog can be forward-modeled from the Gaia scanning law, including individual 1D astrometric measurements, the fitting of a cascade of astrometric models, and quality cuts applied in post-processing. We populate a synthetic Milky Way model with binary stars and generate a mock catalog of astrometric orbits. The mock catalog is quite similar to the DR3 astrometric binary sample, suggesting that our selection function is a sensible approximation of reality. Our fitting also produces a sample of spurious astrometric orbits similar to those found in DR3; these are mainly the result of scan angle-dependent astrometric biases in marginally resolved wide binaries. We show that Gaia's sensitivity to astrometric binaries falls off rapidly at high eccentricities, but only weakly at high inclinations. We predict that DR4 will yield $\sim 1$ million astrometric orbits, mostly for bright ($G \lesssim 15$) systems with long periods ($P_{\rm orb} \gtrsim 1000$ d). We provide code to simulate and fit realistic Gaia epoch astrometry for any data release and determine whether any hypothetical binary would receive a cataloged orbital solution.

description: The growing penetration of electric vehicles (EVs) significantly changes typical load curves in smart grids. With the development of fast charging technology, the volatility of EV charging demand is increasing, which requires additional flexibility for real-time power balance. The forecasting of EV charging demand involves probabilistic modeling of high dimensional time series dynamics across diverse electric vehicle charging stations (EVCSs). This paper studies the forecasting problem of multiple EVCS in a hierarchical probabilistic manner. For each charging station, a deep learning model based on a partial input convex neural network (PICNN) is trained to predict the day-ahead charging demand's conditional distribution, preventing the common quantile crossing problem in traditional quantile regression models. Then, differentiable convex optimization layers (DCLs) are used to reconcile the scenarios sampled from the distributions to yield coherent scenarios that satisfy the hierarchical constraint. It learns a better weight matrix for adjusting the forecasting results of different targets in a machine-learning approach compared to traditional optimization-based hierarchical reconciling methods. Numerical experiments based on real-world EV charging data are conducted to demonstrate the efficacy of the proposed method.

description: Precision measurements of neutrino interaction cross sections will be of
 critical importance to the next generation of neutrino oscillation
 experiments. The Short-Baseline Near Detector (SBND) is a 112 ton Liquid
 Argon Time Projection Chamber experiment in the Booster Neutrino Beam at
 the Fermi National Accelerator Laboratory in Illinois. It will collect the
 largest ever dataset of neutrino-argon interactions with which it will
 pursue a rich cross section measurement program. This thesis presents the
 development of a number of tools for the reconstruction and analysis of
 this data to prepare SBND for precision measurements. The ability of SBND
 to make a measurement of the challenging NC 1π0 channel is then explored.
 This channel is of particular interest due to its similar signature to the
 charged-current electron neutrino interactions that represent the signal
 of interest in the MiniBooNE and LSND low energy excess. SBND will
 investigate this excess as part of the Short-Baseline Neutrino program.
 Powerful selections reduce the background to this channel by over 99 %,
 whilst retaining 34 % of the signal. A method for extracting the
 interaction cross section is then developed, including an assessment of a
 range of systematic uncertainties associated with the simulation chain. By
 comparing the extracted cross section from a sample of simulated SBND data
 to the raw predictions from a couple of different generator models, it is
 clear that significant differences will be resolvable with SBND data.
 Critical further work is detailed that will enable full exploitation of
 the generational advancement in precision measurements of neutrino-argon
 interaction cross sections possible with SBND.

description: The automotive industry has witnessed a significant transformation in recent years, largely
driven by the emergence of electric powertrains. These systems offer a cleaner and more efficient
alternative to traditional internal combustion engines, marking a pivotal shift towards
sustainability in the transportation sector. At the heart of electric vehicles (EVs) lies the powertrain,
a complex assembly of components tasked with converting electrical energy into mechanical
power to propel the vehicle. In the context of electric race cars, the design and optimization of the
powertrain are of utmost importance to achieve high performance on the track. The powertrain
typically consists of four major components: the motor, inverter, battery, and gearbox. Each of
these components plays a critical role in ensuring the efficient conversion and utilization of
electrical energy to drive the vehicle forward. The process of designing an electric race car
powertrain begins with a thorough understanding and explanation of each component's function
and contribution to overall performance. This foundational understanding serves as the basis for
subsequent analysis and optimization efforts. Central to the design process is the selection and
configuration of the motor and battery, two key components that heavily influence the vehicle's
performance characteristics. To facilitate this decision-making process, engineers leverage
specialized software tools such as OptimumLap, MATLAB, and Simulink. OptimumLap allows
engineers to input relevant parameters of the race car, such as its drag coefficient and frontal area,
to gain insights into its aerodynamic performance. By conducting simulations on specific race
tracks, such as the Adelaide circuit, engineers can generate valuable data representing the vehicle's
performance in terms of lap times and speed. MATLAB's Grabit tool is then utilized to extract
velocity data from the simulation results, providing crucial input for further analysis. This data is
used to create a comprehensive table of values representing the vehicle's velocity profile under
different conditions.
Finally, engineers develop a Simulink model to simulate the operation of the electric
powertrain under various scenarios. This model allows for the extraction of critical performance
metrics and parameters, enabling engineers to optimize the motor and battery configuration to meet
the specific requirements and constraints of the race car.

description: Enterprise Resource Planning (ERP) systems have been adopted by many Iranian organizations in these days. These systems have revolutionized organizational computing by facilitating integrated and real-time planning, production, and customer response. While some companies have achieved significant efficiencies through ERP, others have complained of failed implementations, budget overrun, and disappointing performance. This dissertation draws upon Diffusion of Innovation (DOI) theory and Information System Success (IS) theory to test the effective variables on ERP implementation success. Data were collected using survey through the companies that purchase ERP. Data Analysis has performed with Anova Test, T Test, CFA and SEM.The period of this study is the autumn of 1391. Results reveal that competitive pressure are positively related to user satisfaction and organizational performance. On the other hand, the influence of user satisfaction on organizational performance is significant. While percieved complexity, training and top management support are positively related with satisfaction of operational managers, but don’t have a role in improving organizational performance. It seems that these variables just lead to increase user satisfaction.
Curse of dimensionality in the application of pivot-based indexes to the similarity search problem
Creators: name: Volnyansky, Ilya
Publisher: name: Université d'Ottawa / University of Ottawa

Subjects: subject: Mathematics.

description: In this work we study the validity of the so-called curse of dimensionality for indexing of databases for similarity search. We perform an asymptotic analysis, with a test model based on a sequence of metric spaces (O d) from which we pick datasets Xd in an i.i.d. fashion. We call the subscript d the dimension of the space Od (e.g. for Rd the dimension is just the usual one) and we allow the size of the dataset n = nd to be such that d is superlogarithmic but subpolynomial in n. We study the asymptotic performance of pivot-based indexing schemes where the number of pivots is o(n/d). We pick the relatively simple cost model of similarity search where we count each distance calculation as a single computation and disregard the rest. We demonstrate that if the spaces Od exhibit the (fairly common) concentration of measure phenomenon the performance of similarity search using such indexes is asymptotically linear in n. That is for large enough d the difference between using such an index and performing a search without an index at all is negligeable. Thus we confirm the curse of dimensionality in this setting.

Advancing Mathematical Epidemiology and Chemical Reaction Network Theory via Synergies Between Them

Publisher: name: arXiv
Year: 2024

description: Our paper reviews some key concepts in chemical reaction network theory and mathematical epidemiology, and examines their intersection, with three goals. The first is to make the case that mathematical epidemiology (ME), and also related sciences like population dynamics, virology, ecology, etc., could benefit by adopting the universal language of essentially non-negative kinetic systems as developed by chemical reaction network (CRN) researchers. In this direction, our investigation of the relations between CRN and ME lead us to propose for the first time a definition of ME models, stated in Open Problem 1. Our second goal is to inform researchers outside ME of the convenient next generation matrix (NGM) approach for studying the stability of boundary points, which do not seem suficiently well known. Last but not least, we want to help students and researchers who know nothing about either ME or CRN to learn them quickly, by offering them a Mathematica package "BootCamp", located at https://github.com/adhalanay/epidemiology_crns, including illustrating notebooks (and certain sections below will contain associated suggested notebooks; however, readers with experience may safely skip the bootcamp). We hope that the files indicated in the titles of various sections will be helpful, though of course improvement is always possible, and we ask the help of the readers for that.
"La Prophétie des Ombres" suivi de La symbolique du mythe dans le conte merveilleux: Entre traditions et interculturalisme
Creators: name: Danielou, Élodie
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2009
Subjects: subject: Folklore.
subject: Literature, General.

description: Dans la première partie de cette thèse, on trouvera le conte merveilleux La Prophétie des Ombres. Il tire certains thèmes et mythèmes de mythes et contes bretons et algonquiens. Sous leur propre influence, les figures mythiques ont échangé noms et caractéristiques. Laboratoire expérimental, La Prophétie des Ombres s'est transformé en un véritable mythe littéraire. La seconde partie offre une réflexion sur l'influence du mythe en littérature. Je me suis d'abord employée à définir le mythe, le conte et la légende. Puis, j'ai présenté l'histoire de la théorie du mythe littéraire et de la mythocritique. Dans un deuxième chapitre, j'ai analysé les théories de l'intertextualité afin de mieux comprendre comment la structure mythique est reprise dans le récit littéraire, et donc, dans mon processus d'écriture. J'y ai également défini le symbole. Enfin, le quatrième chapitre conclut l'étude en montrant comment je me suis appuyée sur ces théories pour construire une structure mythique et comment cela m'a permis de repenser mon travail d'écriture.

Creators: name: Afrose, Mst Faujiya
Publisher: name: Swinburne
Year: 2024

description: Polylactic acid (PLA), made from renewable sources, is a compostable and biodegradable thermoplastic polymer. PLA material is used for producing consumer products in different applications such as building, agriculture, transportations, electrical appliances and houseware. Therefore, the study of PLA properties becomes an important issue now-a-days. Current industrial processing techniques are time consuming and expensive. To overcome such difficulties fused deposition method (FDM) has extensively been used to quickly produce such industrial purpose physical objects. Therefore, the thesis was focused to investigate and analyse the effects of different FDM build parameters on PLA properties and find out the best build parameter.
