Our study focuses on the impacts of exclusion and discrimination that permeate the threads of the narrative warp of the selected writers to compose our literary corpus in attempt to “break with the silence” imposed by the White Privilege, thereby promoting a rereading of post-colonial and counter-hegemonic features of contemporary Canada. Developed as a review of the historical, literary and cultural Canadian context, casting a closer look at the writing of Asian Canadian minority (women of color), part of the significant production of Asian peoples whom migrated to that country and often bring to light memories of the past and experiences of the present. Furthermore, we present a necessary understanding of such a multiple country as Canada by discussing the concept of transculturation (or transculturality) that greatly assists us in reading the analyzed narratives, highlighting the intensity through which these texts are crossed by linguistic and various cultural references. Finally, we focus on and confront the traditional concepts of Bildungsroman, or novel of development, which brings to discussion critical voices mainly linked to feminism and literary criticism in the broadest sense, in order to highlight what innovations the transcultural Bildungsroman produced by women brings to the analysis of contemporary literature in the Canadian context. Thus, the chosen novels are open to experiences marked by transculturalism and so this genre - the Bildungsroman - becomes the appropriate space for alternative formulations with regard to the characters, especially to female characters. We argue, therefore, that the Bildungsroman, in this context, creates space to minority literatures, here connected to Japanese and Indian ethnicities, as the locus for presenting the conflicts and negotiations between ancestral and after contact cultures. / Cette étude analyse, par le biais de comparaison, les romans Obasan (1981), de Joy Kogawa, et Everything Was Good-Bye (2010), de Gurjinder Basran, écrivains canadiens insérés dans la diaspora canado-asiatique, en se concentrant sur les répercussions de l'exclusion et de la discrimination qui imprègnent ces récits d'écrivains sélectionnés pour composer notre corpus littéraire. Nous comprenons les écrits des deux auteurs comme des tentatives littéraires pour briser le silence imposé par le privilège blanc, promouvant une relecture de caractère post-coloniale et contre hégémonique du Canada contemporain. Nous développons, ainsi, une révision du contexte historique, littéraire et culturel canadiens, en jetant un regard de plus près à l'écriture de la minorité canado-asiatique (femmes de couleur), une partie de la production significative des peuples asiatiques qui ont migré vers ce pays et qui exposent souvent les mémoires du passé et les expériences du présent. Après cela, nous avons développé une compréhension nécessaire du contexte en tant que pays diversifié en discutant le concept de transculturation (ou transculturalité) qui nous aide grandement à la lecture des récits concernés, montrant l'intensité avec laquelle ces textes mélangent des références linguistiques et culturelles diverses. Enfin, nous nous concentrons et confrontons les concepts traditionnels de Bildungsroman, ou roman de formation, en ramenant les voix critiques liées au féminisme et à la critique littéraire dans le sens le plus large, afin de mettre en évidence les innovations que le Bildungsroman (Roman d'apprentissage) transculturel produit par des femmes apporte à l'analyse de la littérature contemporaine dans le contexte canadien. Ainsi, les romans choisis s’ouvrent aux expériences de négociation proposées par la transculturalité existant dans le genre - Bildungsroman - un espace adéquat à des formulations alternatives en ce qui concerne les personnages, surtout les femmes. Nous soutenons, par conséquent, que le Bildungsroman, dans ce contexte, créé un nouvel espace à la littérature des minorités comme un lieu approprié pour présenter les conflits et les négociations entre la culture antique et celle d’arrivée, ici envisagée par les ethnies nippone et indienne. / O presente estudo analisa, pelo viés comparativo, os romances Obasan (1981), de Joy Kogawa, e Everything Was Good-Bye (2010), de Gurjinder Basran, escritoras canadenses inseridas na diáspora asiático-canadense, enfocando os impactos da exclusão e discriminação que permeiam essas narrativas das escritoras selecionadas para compor nosso corpus literário.

Human skin is made of a stack of different layers, each of which reflects a portion of impinging light, after absorbing a certain amount of it by the pigments which lie in the layer. The main pigments responsible for skin color origins are melanin and hemoglobin. Skin segmentation plays an important role in a wide range of image processing and computer vision applications. In short, there are three major approaches for skin segmentation: rule-based, machine learning and hybrid. They differ in terms of accuracy and computational efficiency. Generally, machine learning and hybrid approaches outperform the rule-based methods but require a large and representative training dataset and, sometimes, costly classification time as well, which can be a deal breaker for real-time applications. In this work, we propose an improvement, in three distinct versions, of a novel method for rule-based skin segmentation that works in the YCbCr color space. Our motivation is based on the hypotheses that: (1) the original rule can be complemented and, (2) human skin pixels do not appear isolated, i.e. neighborhood operations are taken into consideration. The method is a combination of some correlation rules based on these hypotheses. Such rules evaluate the combinations of chrominance Cb, Cr values to identify the skin pixels depending on the shape and size of dynamically generated skin color clusters. The method is very efficient in terms of computational effort as well as robust in very complex images. / A pele humana é constituída de uma série de camadas distintas, cada uma das quais reflete uma porção de luz incidente, depois de absorver uma certa quantidade dela pelos pigmentos que se encontram na camada. Os principais pigmentos responsáveis pela origem da cor da pele são a melanina e a hemoglobina. A segmentação de pele desempenha um papel importante em uma ampla gama de aplicações em processamento de imagens e visão computacional. Em suma, existem três abordagens principais para segmentação de pele: baseadas em regras, aprendizado de máquina e híbridos. Elas diferem em termos de precisão e eficiência computacional. Geralmente, as abordagens com aprendizado de máquina e as híbridas superam os métodos baseados em regras, mas exigem um conjunto de dados de treinamento grande e representativo e, por vezes, também um tempo de classificação custoso, que pode ser um fator decisivo para aplicações em tempo real. Neste trabalho, propomos uma melhoria, em três versões distintas, de um novo método de segmentação de pele baseado em regras que funciona no espaço de cores YCbCr. Nossa motivação baseia-se nas hipóteses de que: (1) a regra original pode ser complementada e, (2) pixels de pele humana não aparecem isolados, ou seja, as operações de vizinhança são levadas em consideração. O método é uma combinação de algumas regras de correlação baseadas nessas hipóteses. Essas regras avaliam as combinações de valores de crominância Cb, Cr para identificar os pixels de pele, dependendo da forma e tamanho dos agrupamentos de cores de pele gerados dinamicamente. O método é muito eficiente em termos de esforço computacional, bem como robusto em imagens muito complexas.

A presente pesquisa consiste em analisar a solidez da cor dos substratos têxteis à lavagem, perante a utilização de detergentes em pó comerciais, e comparar com a utilização do detergente pó padrão previsto na norma ABNT NBR ISO 105-C06: Têxteis Ensaios de solidez da cor parte C06: Solidez da cor à lavagem doméstica e comercial. Para que as variáveis do substrato têxtil: a) composição; b) preparação para o tingimento; c) processo de tingimento; d) intensidade da cor; e) classe de corante. E as do processo de lavagem: temperaturas não comprometessem a conclusão da pesquisa, contemplou-se o controle de todas elas, de forma que, a única variável foi o tipo de detergente em pó utilizado, para tanto, levou-se em consideração: a) utilizado substratos 100% algodão, 100% poliéster, 100% poliamida e 100% acrílico; b) preparação para garantir a homogeneidade das amostras; c) substratos tintos em cores claras, médias e escuras; d) utilizadas classes de corantes que possuem boa solidez à lavagem; e) lavagem a 40ºC e a 60ºC. Foi utilizado um ambiente integrado contemplando equipamentos de laboratório para preparação, tingimento das amostras e para os ensaios de solidez da cor à lavagem, segundo a norma técnica específica. Os corpos de prova, após o processo de lavagem, foram submetidos à avaliação da alteração da cor, de acordo com a norma ABNT NBR ISO 105-A05: Têxteis Ensaios de solidez da cor parte A05: Avaliação instrumental da alteração da cor para classificação na escala cinza. Os resultados dos ensaios apontaram que somente os substratos 100% algodão e 100% poliamida, cor clara, lavados com detergentes comerciais apresentam resultados divergentes dos lavados com detergente padrão. Já os demais substratos não apresentaram alterações significativas quando comparados aos resultados obtidos na lavagem com o detergente padrão, o que aponta que o tipo de detergente utilizado no ensaio não influencia no resultado / The present research consists in analyzing the fastness of colors in textile substrates to washing, in relation to the use of commercial powder detergents, and compare it with the use of the standard detergent powder according to ABNT NBR ISO 105-C06: Textiles - color fastness of C06: Color fastness to domestic and commercial washing. So that the variables of the textile substrate: a) composition; b) preparation for dyeing; c) dyeing process; d) color intensity; e) dye class. And the of washing process: temperature, did not compromise the conclusion of the research, it was contemplated the control of them all, so that the only variable was the type of detergent powder used, for that, it was taken into consideration: a) used 100% cotton, 100% polyester, 100% polyamide and 100% acrylic substrates, because they are the most consumed fibers in Brazil; b) preparation to guarantee the homogeneity of the samples; c) red substrates in light, medium and dark colors; d) classes of dyes, which have good wash fastness, were used; e) washing at 40 ° C and at 60 ° C. An integrated environment was used, contemplating laboratory equipment for preparation, dyeing of the samples and the tests of color fastness to the wash, according to the specific technical standard. After the washing process, the specimens were submitted to the color change evaluation according to ABNT NBR ISO 105-A05: Textiles - Color fastness tests part A05: Instrumental evaluation of the color changing for Classification on the gray scale. The results of the tests indicated that only the 100% cotton and 100% polyamide substrates light colored washed with commercial detergents showed divergent results from the standard detergent washings. However, on the other substrates, did not present significant alterations when compared to the substrates obtained in washing with standard detergent, which indicates that the type of Detergent used in the test does not influence the result

When forensic examiners try to identify the perpetrator of a felony, they use individual facial marks when comparing the suspect with the perpetrator. Facial marks are often used for identification and they are nowadays found manually. To speed up this process, it is desired to detect interesting facial marks automatically. This master thesis describes a method to automatically detect and separate permanent and non-permanent marks. It uses a fast radial symmetry algorithm as a core element in the mark detector. After candidate skin mark extraction, the false detections are removed depending on their size, shape and number of hair pixels. The classification of the skin marks is done with a support vector machine and the different features are examined. The results show that the facial mark detector has a good recall while the precision is poor. The elimination methods of false detection were analysed as well as the different features for the classifier. One can conclude that the color of facial marks is more relevant than the structure when classifying them into permanent and non-permanent marks. / När forensiker försöker identifiera förövaren till ett brott använder de individuella ansiktsmärken när de jämför den misstänkta med förövaren. Dessa ansiktsmärken identifieras och lokaliseras oftast manuellt idag. För att effektivisera denna process, är det önskvärt att detektera ansiktsmärken automatiskt. I rapporten beskrivs en framtagen metod som möjliggör automatiskt detektion och separation av permanenta och icke-permanenta ansiktsmärken. Metoden som är framtagen använder en snabb radial symmetri algoritm som en huvuddel i detektorn. När kandidater av ansiktsmärken har tagits, elimineras alla falska detektioner utifrån deras storlek, form och hårinnehåll. Utifrån studiens resultat visar sig detektorn ha en god känslighet men dålig precision. Eliminationsmetoderna av falska detektioner analyserades och olika attribut användes till klassificeraren. I rapporten kan det fastställas att färgskiftningar på ansiktsmärkena har en större inverkan än formen när det gäller att sortera dem i permanenta och icke-permanenta märken.

Dans le domaine de l’optique, les savants ont réfléchi, depuis l’Antiquité, aux couleurs. Dans les beaux-arts, par sa nature accidentelle, la couleur a été traitée comme un élément inférieur au dessin. L’enseignement scolaire a suivi cette tendance. Cependant, au milieu du XIXe siècle, apparaissent divers ouvrages de vulgarisation traitant des couleurs. Leur point de vue est alors le savoir-vivre, l’éducation, l’ésotérisme, l’optique, l’art ou la technologie. Notre thèse a pour objectif de comprendre en quoi le traitement des couleurs est original dans les poèmes en vers de Rimbaud, en relation avec l’épistémè du XIXe siècle. Dans les poèmes de Rimbaud, les couleurs parlent du poète ; de son éducation, ses préoccupations, sa pensée politique ou religieuse et même l’enjeu poétique de son œuvre. Nous nous sommes concentré sur le symbole des couleurs, négligé jusqu’à présent, et sur les effets physiologiques et les impressions visuelles dont Goethe ou Chevreul ont traité. Rimbaud n’invente ni les couleurs spectrales, ni les correspondances entre sons et couleurs, ni le symbolisme des couleurs. Il s’inspire d’idées existantes, et les combine pour inventer une nouvelle langue poétique. Il superpose les couleurs symboliques provoquant des associations d’idées, aux couleurs spectrales. Dans « Voyelles », le poète implique sa méthode dans la description de l’arc-en-ciel, dans l’évocation sonore des lettres de l’alphabet grec et dans le symbolisme de cinq couleurs. L’originalité de sa démarche tient à la convergence de ses différents moyens d’expression. C’est cet emploi des couleurs qui contribue à la création d’une nouvelle langue poétique. / In the field of optics, scientists have studied colors since ancient times. In Arts, because of its accidental nature, color is treated as a element lower than drawing. School education has followed this tendency to neglect the color. However, during the mid-nineteenth century appeared various books about colors, in the fields of etiquette, education, esotericism, optics, art and technology. Our objective is to find what makes the use of colors unique in the verse poems of Rimbaud, in consideration of the nineteenth century episteme. In his poems, colors speak of the poet; his education, his concerns, his political or religious thought and his poetics. We focused on the symbols of colors, which was neglected so far, and on the physiological effects and visual impressions treated by Goethe and Chevreul. Rimbaud do not invent neither the spectral colors, nor the correspondences between sounds and colors, nor color symbolism. He draws inspiration from existing ideas, and combines them to invent a new poetic language. He superimposes symbolic colors creating associations of ideas, on spectral colors, which maintain order in optics. In "Voyelles", he introduces his poetics through the description of a rainbow, the sonorous evocation of letter of the Greek alphabet, and the symbols of five colors. The originality of his approach lies in the convergence of its different means of expression. His use of color thus leads to the creation of a new poetic language.episteme.

Life history traits affect the timing and pattern of maturation, reproduction, and survival during an organism’s lifecycle and are the major components influencing Darwinian fitness. Co-evolved patterns of these traits are known as life history strategies (LHS) and variation occurs between individuals, populations, and species. The polymorphisms underlying LHS are important targets of natural selection, yet the underlying genes and physiological mechanisms remain largely unknown. Mapping the genetic basis of a LHS and subsequently unraveling the associated physiological mechanisms is a challenging task, as complex phenotypes are often polygenic. However, in several systems discrete LHS are maintained within the population and are inherited as a single locus with pleiotropic effects. These systems provide a promising starting point for investigation into LHS mechanisms and this thesis focuses on one such strategy - the Alba polymorphism in Colias butterflies. Alba is inherited as a single autosomal locus, expressed only in females, and simultaneously affects development rate, reproductive potential, and wing color. Alba females are white, while the alternative morph is yellow/orange. About 28 of 90 species exhibit polymorphic females, though whether the Alba mechanism and associated tradeoffs are conserved across the genus remains to be determined. In this thesis I primarily focus on the species Colias croceus and integrate results from lipidomics, transcriptomics, microscopy, and genomics to gain insights to the proximate mechanisms underlying Alba and Alba’s evolution within the genus. Lipidomics confirm that, consistent with findings in New World species, C. croceus Alba females have larger abdominal lipid stores than orange, an advantage which is temperature dependent and arises primarily due to mobilized lipids. Gene expression data suggests differences in resource allocation, with Alba females investing in reproduction rather than wing color, consistent with previous findings in other Colias species. Additionally, I identify a morphological basis for Alba’s white wing color. Alba females from C. croceus, an Old World species, and Colias eurytheme, a New World species both exhibit a significant reduction in pigment granules, the structures within the wing scale that contain pigment. This is a trait that seems to be unique to Colias as other white Pierid butterflies have an abundance of pigment granules, similar to orange females. I also map the genetic basis of Alba to a single genomic region containing an Alba specific, Jockey-like transposable element insertion. Interestingly this transposable element​ is located downstream of BarH-1, a gene known to affect pigment granule formation in Drosophila. Finally, I construct a phylogeny using a global distribution of 20 Colias species to facilitate investigations of Alba’s evolution within the genus. / <p>At the time of the doctoral defense, the following papers were unpublished and had a status as follows: Paper 2: Manuscript.

Denna studie handlar om hur man med färg och rumslig formgivning kan öka orienterbarheten i en sjukhusmiljö, med fokus på huvudentrén. Studien är ett examensarbete i Informationsdesign, med inriktningen rumslig gestaltning. Platsen för studien har varit huvudentrén på Avesta lasarett. Huvudentréhallen på Avesta lasarett upplevs idag som trång och uppfyller inte de behov som finns. Syftet med studien har varit att med hjälp av tidigare forskning och teorier, samt empiriska studier, hitta ett sätt att öka orienterbarheten i en sjukhusmiljö. Detta med hjälp av en rumslig formgivning och ett skyltsystem som stödjer entréns funktioner och aktiviteter. Vilket ska bidra till att underlätta för besökare att hitta rätt i en ansträngande och stressig situation som ett sjukhusbesök kan innebära. Teorierna som studien grundar sig i behandlar wayfinding och wayshowing, kognition, det fysiska rummet, teorier om hälsa och välmående, samt teorier om färg och färgkodning. Metoderna som använts för den empiriska datainsamlingen är platsanalys, observationer och kvalitativa intervjuer. Arbetet har resulterat i ett färgkodningssystem som tillämpats i det befintliga skyltsystemet samt i rumsutformningen. Detta för att skapa en visuellt strukturerad huvudentré där vägledande skyltar samspelar med rummet och dess användningsområden. / This study is about how colour and spatial design can increase the orientation in a hospital environment, focusing on its main entrance. The study is a degree project in Information Design, with a focus on spatial design.  The location of the study has been the main entrance to Avesta hospital. The main entrance hall of Avesta hospital is today perceived as cramped and does not meet the needs. The aim of the study has been to find ways to increase the orientability of a hospital environment with the help of previous research and theories, as well as empirical studies. This is done using a spatial design and a sign system that supports the entrance functions and activities. Which, in turn, will help to make it easier for visitors to find the right way in an exhausting and stressful situation that a hospital visit may involve.  The theories which the study is based on deals with wayfinding and wayshowing, cognition, physical space, theories of health and well-being, as well as theories of color and color coding. The methods used for the empirical data collection are site analysis, observations and qualitative interviews.  The work has resulted in a color coding system which is being applied in the existing sign system as well as in the room layout. This is to create a visually structured main entrance where indicative signs interact with the design of the room and its uses.
