Primeiramente, estabelecemos um diálogo entre o pensamento filosófico de Beauvoir e o de Murdoch. Posteriormente, estabelecemos uma relação entre a crítica literária feminista e o pensamento beauvoiriano e murdochiano no que tange a questão do papel da mulher como leitora e escritora de textos literários. Dessa forma, examinamos o papel do leitor(a) como instância fundamental no processo de desconstrução do caráter discriminatório das ideologias de gênero e demonstramos que, assim como Virginia Woolf, Beauvoir e Murdoch defendem o conceito de androginia na literatura. Finalmente, analisamos os diferentes recursos estéticos que Beauvoir e Murdoch utilizam na caracterização de suas personagens femininas, uma vez que La Femme Rompue apresenta as características de um romance moderno, enquanto A Fairly Honourable Defeat possui traços de um romance realista / The aim of this research is to address some aspects of feminism from a feminist Anglo-American critical stance in two fictional works that have been published in the late sixties and early seventies: La Femme Rompue (1967) by Simone de Beauvoir (1908-1986) and A Fairly Honourable Defeat (1970) by the Irish writer Iris Murdoch (1919-1999). First, we establish a dialogue between the philosophical thought of Beauvoir and Murdoch. Then, we firm a relationship between feminist literary criticism and Beauvoir's and Murdoch's thoughts regarding the issue of women's role as a reader and as a writer of literary texts. Thus, we explore the role of the reader as a key instance in the process of deconstruction of the discriminatory nature of gender ideologies and we demonstrate that, just as Virginia Woolf, Beauvoir and Murdoch defended the concept of androgyny in literature. Finally, we analyze the different aesthetic features that Beauvoir and Murdoch use in the characterization of female characters, since La Femme Rompue presents the characteristics of a modern novel while A Fairly Honourable Defeat has some traces of a realist novel

Os sistemas biométricos vem ganhando destaque em soluções ligadas à segurança, uma vez que tratam de características físicas e comportamentais para reconhecimento dos indivíduos e permissões de acesso. Este trabalho objetivou a proposição e implementação de um método para reconhecimento de indivíduos por meio de características contidas na região interna da íris com um alto percentual de exatidão no reconhecimento e uma grande diminuição no tempo de processamento, se comparado aos demais métodos encontrados na literatura. No método proposto foram utilizados operadores de morfologia matemática para localização da íris, wavelet de log-Gabor para extração das características e a distância de Hamming para o reconhecimento. Os resultados experimentais obtidos utilizando a base de dados CASIA mostraram que o método é confiável e seguro, além de se destacar com relação ao baixo custo computacional / In the recent years, the security became a constant concern of most people. Biometric systems have been highlighted in solutions related to security, since they deal with physical and behavioral characteristics for individuals recognition and access permissions. This work aims at the implementation of a method for individuals recognition based on the characteristics of the inner region of the iris, seeking a high percentage of accuracy in the recognition and a great reduction in the processing time, as compared to other methods published so far. We use mathematical morphology to search the iris in the image, the log-Gabor wavelet for feature extraction and the Hamming distance for recognition. The experimental results obtained from CASIA database show that the method is safe and reliable, and stand out with regard to the low computational cost

Semantic desktop focusing on harvesting domain specific information in planningaid documents / A Model for Processing Document in IRIS Semantic Desktop SystemEtezadi, Ali Reza January 2008 (has links)
Planning is indeed a highly regulated procedure at the operational level such as military related activities where the staff may benefit from documents such as guidelines that regulate the work process, responsibilities and results of such planning activities. This thesis proposes a method for analyzing office documents that make up an operational order according to document ontology. With the semantic desktops aiming at combining semantic annotations and intelligent reasoning in desktop computers, the product of this project intends to add a plug-in to such environments such as IRIS semantic desktop, which accordingly enables such application to interpret documents whether the they or change within the application. The result of our work helps the end user to extract data using his/her favorite patterns such as goals, targets or even milestones that make up decisive points. This information eventually form semantic objects, which ultimately reside in the knowledgebase of the semantic desktop for further reasoning in the future referring of the application, whether automatically or upon the user's request.

Iris Clert (1918-1986), une galeriste singulière / Iris Clert (1918-1986), a singular galleristBergeret, Servin 15 June 2017 (has links)
Iris Clert (1918-1986) est une figure emblématique du monde de l'art contemporain parisien de la seconde moitié du XXe siècle, et plus particulièrement des années 1960. L'histoire de l'art semble n’avoir retenu que des bribes de son existence et de la galerie d'art contemporain qu'elle dirigea à Paris de 1956 à 1982. En effet, sa postérité repose exclusivement sur la place considérable qu'elle a tenue dans la promotion de l’oeuvre d'Yves Klein et dans l'émergence du groupe d'artistes des Nouveaux-Réalistes. Pourtant, Iris Clert n’est-elle pas la première galeriste à avoir proposé au public parisien des oeuvresd’Ad Reinhardt, Lucio Fontana et Leon Golub ? Puis, à force de renouveler et de transgresser les méthodes et pratiques habituellement assignées à sa profession, Iris Clert n’annonce-t-elle pas l’élan pris par l’art vers la participation et l'événementiel ? N’est-elle pas à l’origine de véritables politiques culturelles ? N’a-t-elle pas été elle-même une artiste ? Aussi, à force de se raconter et de s'identifier à l'art, n’a-t-elle pas tenté de se construire une mythologie personnelle, afin d’apparaître telle l’œuvre de sa galerie ? Faire de l’art une attitude de vie, provoquer, scandaliser, formuler des revendications ambiguës, se jouer des normes, se fier à son instinct plus qu'à la raison, être partout sans limites… voici les ambitions d’Iris Clert, elle qui affirmait en 1975 : « J’ai un destin, je suis la messagère des dieux, donc des artistes ! » / Iris Clert (1918-1986) is a key figure in the world of the Parisian contemporary art of the sixties. Art history seems to have only kept recollection of fragments of her life and of the contemporary art gallery she ran in Paris from 1956 to 1982. Her posterity is only based on the significant part she played in promoting Yves Klein’s art and New Realism artists.Though, isn’t Iris Clert the first gallery owner who introduced the Parisian audience with Ad Reinhardt, Lucio Fontana and Leon Golub’s art? By keeping reinventing and breaking the usual methods and habits of her field, she anticipates the impulse of art towards participation and events. Wasn’t she the spearhead of a true cultural policy and an actual artist herself? She then tried to build her own mythology by keeping identifying herself with art, to appear as the very work of her gallery. Iris Clert showed her ambitions by making art a way to conduct her life, acting in a provocative and outrageous way, expressing ambiguous demands, defying standards, trusting her instinct over her mind, and being unrestrictedly everywhere. Ambitions which made her say in 1975: “I have a destiny, I am the messenger of the gods, hence of artists”.

Previous issue date: 2010-08-10 / This paper presents a technique to iris detection and tracking that can be used in a human computer interface which allows people with mobility restricted, including no mobility above the shoulders, can control the mouse pointer only moving their eyes, without using expensive equipments. The unique data input used is an ordinary webcam without optical zoon, special lights or restricting user face mobility. The mouse displacement will occur in a straight way, in other words, the mouse cursor will be positioned at the place estimated by the technique. To the iris detection tests 60 images were used. 90.83% of the iris were identified correctly, there were 4.17% of missing iris and 5% false positives (iris were estimated in a wrong place). Using images generated straight from the webcam the iris were found correctly in 87,5%, no iris were found in 11,11% and in 1,39% the technique found iris in wrong places, the average time between positioning and a click is about 20 seconds. / Este trabalho apresenta uma técnica de detecção e rastreamento de íris para ser utilizada em uma interface homem-computador que permita pessoas com mobilidade restrita, inclusive sem mobilidade nos ombros, possam controlar o cursor do mouse com o movimento dos olhos, sem a necessidade de adquirir equipamentos caros. A única entrada de dados utilizada é uma webcam simples sem auxílio de zoon ótico, iluminação especial ou fixação da face do usuário. A movimentação do mouse dar-se-á de maneira direta, ou seja, o ponteiro do mouse será direcionado para a região estimada pela técnica. Para a realização dos testes de detecção de íris foram utilizadas 60 imagens. Em 90.83% dos casos as íris foram encontradas corretamente, 4.17% dos casos não foram identificados e ocorreram 5% de falsos positivos (casos em que as íris foram estimadas no lugar errado). Com as imagens geradas diretamente pela webcam a identificação das íris ocorreu com sucesso em 87,50% dos casos, erros em 11,11 % e 1,39% de falsos positivos, o tempo médio entre o posicionamento e um clique é de cerca de 20 segundos.

Previous issue date: 2006-12-04 / Biometrics identification methods are gaining applications each day and this
has motivated a lot of research in this area. This work presents a proposal
for a method to identify people through iris texture analysis using geostatistics
functions and their combination.
To achieve this work objective, it is considered the following phases: automatic
localization of the iris, features extraction and classification. In the localization
phase, it is used a combination of three techniques: Watershed, Hough Transform
and Active Contours. Each technique has an essential function to achieve a good
performance. Within the extraction phase, there were used four geostatistics
functions (semivariogram, semimadogram, covariogram and correlogram) and a
combination of them to extract this features with a good precision. Finally in the
phase of classification it is used a Euclidean Distance to determine the similarity
degree between the extracted features.
The tests were realised for the phases of localization and classification using
an iris database called CASIA that has 756 images. The results achieved by the
localization method are about 90%. For the classification method, considering
the tests realized with the authentication mode, the obtained results has reached
a success rate of 97.02% for a false acceptance rate equal to zero and 97.22% for
a false acceptance rate equal to a false rejection rate. The tests realized with the
identification mode have reached a rate of success of 98.14%. / Os métodos de identificação biométrica estão ganhando espaço em aplicações
do dia-a-dia o que vem motivando a pesquisa nessa área. Este trabalho apresenta
uma proposta de um método para identificação de pessoas através da análise da
textura da íris usando funções geoestatísticas e uma combinação das mesmas.
Para realização do trabalho foram consideradas as seguintes fases: localização
automática da íris, extração de características e classificação. Na fase de
localização foi usada a combinação de três técnicas Watershed, Transformada
de Hough e Contornos Ativos, onde cada uma possui uma função essencial
para um bom desempenho do processo. Na fase de extração são usadas
quatro funções geoestatísticas (semivariograma, semimadograma, covariograma
e correlograma) e uma combinação das mesmas para extrair características que
discriminem a íris com uma boa precisão. Finalmente, na fase de classificação
é usada a distancia Euclidiana para determinar o grau de similaridade entre as
características extraídas.
Os testes foram realizados, para as fases de localização e classificação, com
um banco de dados de íris, denominado CASIA que possui 756 imagens. Na fase
de localização o resultado alcançado foi de 90%. Para a fase de classificação,
considerando os testes realizados no modo de autenticação, os resultados obtidos
chegaram a uma taxa de sucesso de 97.02% para uma falsa aceitação igual a zero
e de 97.22% para uma falsa aceitação igual a uma falsa rejeição. Para os testes
realizados no modo de identificação a taxa de sucesso chegou a 98.14%.
