Incursing for the analysis of domestic violence within the family with the intersection between gender and generationality required the use of the systemic complexity approach in Edgar Morin which allowed us to look at this problem from several dimensions, allowing us to approximate the real. In this study the term generation is understood within its historical and sociological dimension, trying to show the sociocultural factors that generate the formation of the human generations in Mannheim. Concerning the methodological aspects the research assumed the orientation of the qualitative approaches without excluding the quantitative aspects. The technical procedures used in the collection of primary and secondary data were carried out in a semi-structured interview. The research locus focused on the Specialized Women's Police Station in the Municipality of Parintins, specifically in the Social Service Assistance Center. The sample consisted of 6 women, 3 mothers and 3 daughters, two generations. The technique of content analysis was the tool used to analyze the data obtained. This research contacts the existence of a vicious circle of generational domestic violence in Parintins that emerge in the conjugal relationship proliferating in the generation of the couple's daughters. All this leads to the belief that this generational violence has roots in the environment of violence in families. Something that goes from generation to generation. That is, the same cycle of violence experienced by the mother practiced by his companion is experienced by his daughters. / Este estudo assume o propósito de verificar em que sentido a violência doméstica se estrutura num circulo vicioso geracional, envolvendo as gerações de mães e filhas, tornando naturalizado e cristalizado o fenômeno da violência contra a mulher na sociedade. Trata-se de um tema ancorado na temática de gênero que estabelece um diálogo com saberes interdisciplinar, tendo como base as ciências sociais e o Serviço Social. A abordagem da complexidade sistêmica em Edgar Morin o qual permitiu-nos olhar este problema a partir de várias dimensões, possibilitando-nos uma aproximação do objeto estudado. Neste estudo o termo geração é compreendido no âmbito de sua dimensão histórica e sociológica, buscando mostrar os fatores socioculturais que engendram a formação das gerações humanas em Mannheim. O trabalho de campo assumiu a orientação das abordagens qualitativa sem excluir os aspectos quantitativos. A coleta de dados primários foi realizada sob a técnica da entrevista profunda, segundo a qual, uma mesma pessoa pode ser entrevistada quantas vezes for necessário. O locus da pesquisa concentrou-se na Delegacia Especializada da Mulher no Município de Parintins, especificamente no Núcleo de Atendimento do Serviço Social. A técnica de análise de conteúdo foi a ferramenta utilizada para o exame dos dados obtidos. Dentre os múltiplos aspectos constatados ficou claro a existência de um círculo vicioso da violência doméstica geracional em Parintins que emergem na relação conjugal, proliferando na geração das filhas do casal. Constatamos, outrossim, que a violência geracional tem raízes no ambiente de violência existente nas famílias, algo que vai passando de geração a geração. Ou seja, o mesmo ciclo de violência vivido pela mãe praticado por seu companheiro, é vivenciado pelas filhas.

Classificação das auto-aplicações de fibrados, com fibra toro, que preservam fibra sobre o círculo, com a propriedade de poderem ser deformadas sobre o círculo a uma aplicação livre de ponto fixo. Ainda, investigamos a relação entre o número de Reidemeister sobre o círculo e a propriedade acima / Classification of all fiber-preserving self-maps of torus bundles over the circle by the property of being able to deform them over the circle into a fixed point free map by a fiberwise homotopy over the circle. We also investigate the relationship between Reidemeister number over the circle and the property above

No presente trabalho consideramos homeomorfismos do círculo sem pontos periódicos e com o mesmo número finito de pontos críticos todos de tipo non-flat. Provamos que se existe uma conjugação topológica entre dois destes mapas que leva ponto crítico em ponto crítico, sem necessidade de preservar criticalidades, então dita conjugação é uma transformação quase-simétrica com distorção quase-simétrica local uniformemente limitada. Estes resultados são válidos para qualquer número de rotação irracional e são independentes da natureza das criticalidades dos pontos críticos, de modo que nossos resultados são válidos para toda criticalidade real. / In this work we consider circle homeomorphisms without periodic points and with finite number of critical points all of them being non-flat. We prove that if there exists a topological conjugacy between two of those maps which sends critical point into critical point, which not necessarily preserve criticalities, then this conjugacy is a quasi-symmetric map with quasi-symmetric distortion universally bounded. All these results are valid for any irrational rotation number and are independent of the nature of the criticalities, therefore our results are valid for all real criticalities.

A partir de estudos acerca das teorias sócio-histórico-culturais para o ensino e a aprendizagem, e de uma experiência de aplicação das mesmas na Educação Matemática, apresenta-se uma sequência didática envolvendo noções de semelhança de triângulos, trigonometria no triângulo retângulo, comprimento da circunferência e área do círculo, com o uso de atividades lúdicas e exploratórias. A construção dessa sequência se justifica como algo relevante para a sala de aula, porque se percebe que os conteúdos matemáticos apresentados de forma tradicional já não são atrativos para os alunos. Esta dissertação, aproximando-se de uma pesquisa de caráter qualitativo, busca evidenciar o processo de desenvolvimento dessa sequência didática e sua aplicação em uma sala do 9º ano do Ensino Fundamental, em uma escola pública. Como resultados, verificou-se que o uso de atividades lúdicas e exploratórias propiciou um maior envolvimento dos alunos na busca de conhecimentos acerca dos temas tratados (e também da professora-pesquisadora), de maneira a despertar o raciocínio crítico e reflexivo, conduzindo-os a uma aprendizagem mais significativa, além de possibilitar o desenvolvimento pessoal quanto a habilidades e atitudes. Conclui-se que é possível fazer um trabalho diferenciado na condução do aluno ao conhecimento, mesmo em salas de aula onde há pouca motivação original dos estudantes, com persistência e maior dedicação docente, e espera-se que esta dissertação possa contribuir para inspirar as atividades didático-pedagógicas de outros professores de Matemática. / Based on studies about socio-historical-cultural theories for teaching and learning, and on an experience of applying them in Mathematics Education, a didactic sequence is presented, involving notions of similarity of triangles, trigonometry in the rectangle triangle, the length of the circumference, and the area of the circle, with the use of playful and exploratory activities. The construction of this sequence is justified as relevant, because it is perceived that the mathematical contents presented in a traditional way are no longer attractive for the students. This dissertation, approaching a qualitative research, seeks to highlight the process of development of this didactic sequence and its application in a room of the 9th grade of Elementary School, in a public institution in Brazil. As results, it was verified that the use of playful and exploratory activities led to a greater involvement of the students in the search of knowledge about the subjects treated (and also of the teacher-researcher), in order to awaken critical and reflexive reasoning, leading them to more meaningful learning, and to enable personal development in skills and attitudes. It was concluded that doing a differentiated work in unmotivated classrooms is something feasible, in order to lead the students towards meaningfull knowledge, and it is hoped that this dissertation can contribute to inspire the didactic-pedagogical activities of other Mathematics teachers.

Circle time is a common every day activity in many preschools in Sweden. Circle time goes back a long way when it comes to Swedish preschool history. The preschools of today has a strong belief in the competent child, and the influence of children is supposed to color the entire preschool operation. In circle time, however, we have observed that the influence of children sometimes seems to be forgotten. By observing circle time activities in a preschool based in a suburb in the outskirts of Stockholm, we hope to see just how much children are allowed to make their own decisions, express their opinions, and make suggestions to their preschool teachers that are relevant to that activity. To aid us in the analysis of our observation material, we have harnessed aspects from the new sociology of childhood approach. The core of childhood sociology is that it sees children as active agents in co-constructing practices and understandings of childhood, both in co-ordination and in opposition with adults. With the help of earlier studies, we seek to explore the purposes and functions of circle time, and how that affects the role and the space of action of the children. We also find that when children aren't pleased with what the forced participation circle time includes, they find ways to protest while all the while participating in the activities.

Les cellules de comptage (Malassez, Thoma …) sont conçues pour permettre le dénombrement de cellules sous microscope et la détermination de leur concentration grâce au volume calibré de la grille apparaissant dans l’image microscopique. Le comptage manuel présente des inconvénients majeurs : subjectivité, non-répétabilité… Il existe des solutions commerciales de comptage automatique dont l’inconvénient est de nécessiter un environnement bien contrôlé qu’il n’est pas possible d’obtenir dans le cadre de certaines études (ex. : le glycérol influe grandement sur la qualité des images). L’objectif du projet est donc double : un comptage des cellules automatisé et suffisamment robuste pour être réalisable, quelles que soient les conditions d’acquisition.Dans un premier temps, une méthode basée sur la transformée de Fourier a été développée pour détecter, caractériser et effacer la grille de la cellule de comptage. Les caractéristiques de la grille extraites par cette méthode servent à déterminer une zone d’intérêt et son effacement permet de faciliter la détection des cellules à compter.Pour réaliser le comptage, la problématique principale est d’obtenir une méthode de détection des cellules suffisamment robuste pour s’adapter aux conditions d’acquisition variables. Les méthodes basées sur les accumulations de gradients ont été améliorées par l’adjonction de structures permettant une détection plus fine des pics d’accumulation. La méthode proposée permet une détection précise des cellules et limite l’apparition de faux positifs.Les résultats obtenus montrent que la combinaison de ces 2 méthodes permet d’obtenir un comptage répétable et représentatif d’un consensus des comptages manuels réalisés par des opérateurs. / The counting cells (Malassez, Thoma ...) are designed to allow the enumeration of cells under a microscope and the determination of their concentration thanks to the calibrated volume of the grid appearing in the microscopic image. Manual counting has major disadvantages: subjectivity, non-repeatability ... There are commercial automatic counting solutions, the disadvantage of which is that a well-controlled environment is required which can’t be obtained in certain studies ( eg glycerol greatly affects the quality of the images ). The objective of the project is therefore twofold: an automated cell count and sufficiently robust to be feasible regardless of the acquisition conditions.In a first step, a method based on the Fourier transform has been developed to detect, characterize and erase the grid of the counting cell. The characteristics of the grid extracted by this method serve to determine an area of interest and its erasure makes it easier to detect the cells to count.To perform the count, the main problem is to obtain a cell detection method robust enough to adapt to the variable acquisition conditions. The methods based on gradient accumulations have been improved by the addition of structures allowing a finer detection of accumulation peaks. The proposed method allows accurate detection of cells and limits the appearance of false positives.The results obtained show that the combination of these two methods makes it possible to obtain a repeatable and representative count of a consensus of manual counts made by operators.

As the communication deficit in the Arctic region is enormous especially above 75 [Deg] N latitude, the concern and opportunity of providing reliable & efficient connectivity in the Arctic region has beenduly noted & understood by N66 Connect AB (N66). This case study documents a comprehensive research which implements system engineering approach for establishment of a Ground Station (GS) at Svalbard, Norway with sole focus of connecting the inaccessible geographical region lying in the Arctic with rest of the world. Several GS system & subsystem are studied and comparative analysis is made on how the communication can be established with the N66 Connect AB (N66)’s potential clients and its satellites that are to be deployed in September, 2018.The case study resulted in analysis of several risks involved during development & operation of the GS,the hardware, software & operational architecture, the features of GS’s system capable of meeting N66’s objectives and the market potential of the service after GS operations.

Dans le cadre des services intégrés en périnatalité et pour la petite enfance, le Ministère de la Santé et des Services sociaux du Québec (MSSS, 2016) recommande l’implantation d’interventions préventives basées sur la relation d’attachement parent-enfant. La documentation scientifique actuelle démontre qu’un attachement sécurisant constitue un facteur de protection majeur pour le développement socio-émotionnel de l’enfant, tandis qu’un attachement insécurisant ou désorganisé constitue un facteur de risque associé à la mésadaptation et à la psychopathologie (Sroufe, Carlson, Levy, & Egeland, 1999; Thompson, 2008). Parmi les interventions fondées sur la théorie de l’attachement, le programme Circle of Security Parenting (COS-P) a l’avantage de présenter un contenu accessible et de requérir des ressources limitées, ce qui facilite son implantation (Cooper, Hoffman, & Powell, 2009). De plus, COS-P cible plusieurs caractéristiques parentales jouant un rôle majeur sur la qualité de l’attachement parent-enfant, soit la sensibilité, les représentations parentales et la fonction réflexive parentale (FRP). À ce jour, les démonstrations empiriques de l’efficacité de COS-P à court et à long terme demeurent restreintes. La présente étude pilote a pour objectif d’évaluer les effets potentiels du programme COS-P à court terme (un mois après l’intervention) et à long terme (un an après l’intervention) auprès de quatre mères québécoises d’enfants d’âge préscolaire recevant des services de première ligne. Le devis de recherche pré-expérimental est de type pré-test/post-test à groupe unique avec trois temps de mesure. Suite à COS-P, une amélioration de la FRP et des représentations parentales, soit une augmentation de l’expérience affective positive du parent et de l’enfant et une diminution de l’expérience affective négative du parent et de l’enfant (Parent Development Interview [PDI]; Aber, Slade, Berger, Bresgi, & Kaplan, 1985), sont attendues. L’expérience affective parentale négative est également évaluée à partir d’un questionnaire auto-rapporté (Parenting Stress Index - Short Form [PSI-SF]; Abidin, 1995). De plus, une diminution des problèmes émotionnels et comportementaux de l’enfant est attendue (Child Behavior Checklist [CBCL/1,5-5]; Achenbach & Rescorla, 2000). Les données de groupe pré, post et relance sont comparées et suivies d’une présentation de cas afin d’examiner l’évolution de deux participantes. Les résultats indiquent une diminution significative de l’expérience affective négative des mères, mais l’absence d’évolution significative de la FRP, de l’expérience affective de l’enfant telle que perçue par la mère, de l’expérience affective positive des mères et des problèmes émotionnels et comportementaux des enfants. La réflexion issue de la présentation de cas suggère des hypothèses quant aux facteurs parentaux ayant une possible influence sur l’efficacité de COS-P, soit le degré d’intégration d’expériences traumatiques passées, le soutien reçu ainsi que les caractéristiques socio-économiques. Les conclusions de cette étude pilote mettent en évidence les retombées potentielles de COS-P au plan des représentations parentales ainsi que l’importance d’adapter les interventions selon les facteurs de risque et de protection propres à chaque famille. Les suggestions de recherches futures soulignent la pertinence de poursuivre la démonstration empirique rigoureuse des effets de COS-P à court terme et à long terme.

In many applications, e.g. medical, industrial and military systems, it is of interest to fit a circle to scattered data points belonging to a complete or incomplete circular arc. As an example, circle fitting can be applied in the industry, for quality control, when investigation is required to verify if a manufactured circular object has the desired radius or not. A variety of methods have been developed to handle the circle fitting problem. Some methods are relatively complex and provide more accurate circle fitting, whereas some are simple and fast but lacks accuracy. Furthermore, some methods handle circle fitting better on incomplete circular objects. However, for practical machine vision implementations, there seems to be a lack of study when it comes to circle fitting on largely incomplete circular arcs. Largely incomplete circular arcs refer to short arcs having corresponding angles of few degrees, e.g. less than 10°. Hence, this thesis deals with design and implementation of circle fitting on largely incomplete circular objects. The goal is to investigate the shortest circular arc, i.e. the shortest possible angle that, can be fitted to a circle with an accuracy of at least 98%. The approach includes studying related work, developing a vision based algorithm for circle fitting on incomplete circular objects and conducting experiments using live stream 2D images. We designed and implemented an algorithm, based on a circle fitting algorithm, called Hyper fit. Our experimental set-up, with a 5-Megapixel camera, showed that it is possible to fit a circle, with an accuracy of 98%, to a short circular arc with an angle of only 1.95° of a complete circle. 1.95° corresponds to 0.54% of a complete circles circumference. Results showed that, using a high-resolution camera, it is possible to fit accurate circles on largely incomplete circular arcs. Moreover, the implementation achieved the real-time requirement, as it could process at least 3 fps (frames per second).
