Este trabalho tem como objetivo rever as relações existentes entre os valores obtidos dos ensaios mini-CBR e CBR, a fim de tornar possível a utilização dos resultados de ensaios de mini-CBR no dimensionamento de pavimentos flexíveis, uma vez que este ensaio é mais prático, exige menor quantidade de amostra, é mais rápido para ser executado e exige menor esforço físico na sua realização, sendo, portanto, menos dispendioso que o ensaio de CBR. No desenvolvimento dos ensaios, os resultados indicavam que essas relações não se mostravam adequadas para o universo em estudo, pois quando tentava-se relacionar, graficamente, os resultados dos ensaios tradicionais de CBR com os do mini-CBR, não se obtinham retas como era de se esperar e sim uma nuvem de pontos, indicando não haver correlação entre os dois índices. Desta forma, tentou-se desenvolver novas relações, nos moldes do que fora feito originalmente por Nogami (1972), e correlacionar novamente os valores de carga do ensaio de CBR, para as penetrações de 2,5 e 5,0 mm, com os valores de carga desenvolvidos nos ensaios padronizados de mini-CBR, para as penetrações de 2,0 e 2,5 mm, respectivamente, nas energias de compactação normal e intermediária. Nesta pesquisa são abordados os fundamentos, a descrição e algumas pesquisas realizadas com os ensaios de CBR e de mini-CBR. Foram utilizadas nesta pesquisa 62 amostras de solos do município de São Carlos - SP, as quais foram submetidas ao ensaio de CBR, nas energias de compactação normal e intermediária, e os resultados foram comparados com os dos ensaios de mini-CBR. As amostras foram escolhidas considerando-se a proporcionalidade entre as áreas de ocorrência das classes pedológicas no município de São Carlos. Por fim, apresentam-se as tentativas feitas para aproveitar ao máximo os resultados obtidos nos ensaios de CBR e de mini-CBR. / The objective of this work is to review the relation among the results of mini-CBR and CBR tests.

According to Durham Region Public Health Department, 40% of youth, aged 15-19 years, living in Durham Region said that they had engaged in sexual intercourse in the last year, with 570 youth becoming pregnant. In Durham Region 2.3/100,000 youth between the ages of 15 and 24 years are infected with HIV/AIDS annually. Chlamydia rates have also been steadily increasing with 1,250 cases reported in 2009 in Durham Region, with the rates of STIs in Canada being the highest in youth ages 15 to 24 years. This study was undertaken as a capacity building venture to engage youth in Durham Region and allow them to identify their sexual needs and priorities for HIV prevention and healthy sexual development. The study also had four objectives: (1) To assess whether youth know about the sexual health services that are available to them; (2) To discover how youth perceive the sexual health services they are aware of; (3) To identify where youth currently receive sexual health resources; and (4) To understand where, how and from whom youth would like to receive sexual health resources. The Durham Region Healthy SexYouthality Project was a community-based research study conducted by the Durham Region Healthy SexYouthality Coalition. The Project was a qualitative research study that employed focus group sessions to engage youth in discussions pertaining to their sexual health. The study sample included 32 participants ranging from 15 to 24 years of age, with the mean age of 18.96 years. Of the 32 participants, 19 were female, 12 were male and 1 identified as transgender. The coalition identified four populations within Durham Region; urban, rural, semi-rural and LGBTQ youth, which resulted in 10 focus groups. The size of each meeting ranged from four to nine participants and each was audiotaped. The data was transcribed and then analyzed using open coding with the NVivo 9 software. Several themes about sexual health services emerged from the study. They include: lack of knowledge of services, the need for increased awareness; the perceptions youth have about health services including that they are inaccessible, not anonymous, not confidential, not knowledgeable, are judgemental but are youth-friendly; where youth currently receive information including the internet, media, friends/peers, school, parents and health professionals; and how youth would prefer to receive sexual health education such as through trustworthy internet sources, improved sexual education in schools and new community programs. In conclusion, youth in Durham Region need more information about the sexual health services that are available to them and changes need to be made to make them more accessible, anonymous and confidential. Youth also prefer to access information about sexual health through convenient and reliable sources and it is up to organizations working with youth to ensure that these needs are best being met. / UOIT

Les travaux présentés dans cette thèse ont pour objectif de contribuer à l’élaboration d’un outil d’aide à la décision en conception exploitant de la connaissance générale et de la connaissance contextuelle. L’exploitation de la connaissance générale est effectuée à l’aide d’un moteur de filtrage de contraintes et l’exploitation de la connaissance contextuelle repose sur des principes issus du raisonnement à partir de cas et du data-mining. Le résultat principal est basé sur une notion de contrainte dite "contextuelle". L’idée forte revient à paramétrer une contrainte en fonction du contexte dans lequel celle-ci doit être filtrée. Suivant le niveau de confiance caractérisant la connaissance contextuelle, cette contrainte pourra soit être propagée de manière autonome dans le moteur de filtrage soit être utilisée pour fournir une forme de conseil à l’utilisateur du système d’aide. Nous proposons pour identifier le contexte d’emploi de la contrainte d’utiliser le principe de recherche par similarité très largement utilisé dans les travaux portant sur le raisonnement à partir de cas. Afin de compléter ou d’affiner les informations résultant du filtrage de cette contrainte contextuelle, nous utilisons des algorithmes de comptage issus du data-mining pour fournir des fréquences d’apparition caractérisant une forme de confiance dans le résultat. Nos travaux s’inscrivent dans le cadre d’un projet FUI portant sur la maintenance d’hélicoptère. Le but de notre outil est d’estimer au mieux la charge, le cycle, les coûts des activités opérationnelles de maintenance d’un hélicoptère. L’originalité des travaux est de considérer d’une part les connaissances constructeurs (connaissance générale) pour déterminer une première estimation puis de la corriger suivant les conditions d’utilisation effective de l’hélicoptère (connaissance contextuelle). / The works presented in this thesis aims to contribute to the development of a tool for design decision support exploiting general knowledge and contextual knowledge. The use of general knowledge is performed using a constraint filtering engine the exploitation of contextual knowledge is based on principles derived from case-based reasoning and data mining. The main result relies on a constraint notion called "contextual constraint". The principal idea consists to parameterize a constraint with respect to a context where it must be filtered. Depending on the level of confidence characterizing contextual knowledge, this constraint may either be propagated independently by a filtering engine or being used to provide help to the user. We propose in order to identify the context of the constraint to use the principle of similarity search widely used in case-based reasoning. To complete or refine the information resulting from this constraint contextual filtering, we use counting algorithms developed for data-mining to quantify the occurrence characterizing a kind of confidence in the result. Our work is based on a FUI project relating to helicopter maintenance. The aim of this tool is to better estimate the charge, the cycle, the operational costs of maintenance of an helicopter. The originality of this work is to consider both the manufacturers knowledge (general knowledge) to determine an initial estimate and then to correct it according to the conditions of effective use of the helicopter (contextual knowledge).

This Individual Research Project (IRP) is the extension research to the group design project (GDP) work which the author has participated in his Msc programme. The GDP objective is to complete the conceptual design of a 200-seat, flying wing civil airliner—FW-11. The next generation aircraft design demands higher reliability, safety and maintainability. With the development of the vehicle hydraulic system technology, the equipment and systems become more and more complex, their reliability and maintenance become more difficult for designers, manufacturers and customers. To improve the mission reliability and reduce life cycle cost, there is strong demand for the application of health management technology into airframe system design. In this research, the author introduced diagnostic, prognostic and health management (DPHM) concept into the aircraft hydraulic power system development. As a brand new technology, it is a challenge to apply the DPHM techniques to on-board system. Firstly, an assumed hydraulic power system was designed for FW-11 by the author and used as the case in his IRP research. Then the crucial components and key parameters needed to be monitored were obtained based on Function Hazard Analysis and Failure Modes Effects Analysis of this system. The writer compared a few diagnostic and prognostic methods in detail, and then selected suitable ones for a hydraulic power system. A diagnostic process was applied to the hydraulic power system using a Case-based reasoning (CBR) approach, whilst a hybrid prognostic method was suggested for the system. After that, a diagnostic, prognostic and health management (DPHM) architecture of the hydraulic power system was designed at system level based on the diagnostic and prognostic research. The whole research work provided a general and practical instruction for hydraulic system design by means of DPHM application.

Rationale: Due to the uniqueness of the conflict and post-conflict experience in Bosnia and Herzegovina and limited primary source research, it is unclear to what extent persons with physical disability participate in rehabilitation and other community services. It is uncertain whether persons with physical disability have access to available community programs and services and what role policy, environmental and attitudinal barriers play in community integration and social participation. Objective: The purpose of this study was to understand and describe factors that influence community integration and social participation of persons with a physical disability in post-conflict Bosnia and Herzegovina. Methods: A concurrent embedded mixed methods design was used. Three face to face interviews were conducted and thirteen participants completed written questionnaires adapted from The “KIPA” Clear Direction Strategic Framework: Knowledge-Inclusion-Participation-Access (Edmonds, 2003). Participants had physical disabilities and were recruited through Mojmilo Health Clinic, Centar Za Fizikalnu Theraiji I Rehabilitaciju Community Based Rehabilitation centre and the Clinical Centre University Hospital in Sarajevo, Bosnia and Herzegovina. Results: The study identified challenges and barriers encountered when accessing rehabilitation, primary health care, education and other community services and programs. The data suggested that persons with a physical disability perceived that factors associated with knowledge, inclusion, participation, and access are very important to their quality of life. Government policy reform and assistance, employment opportunities, attitudes and awareness, and community understanding emerged as critical factors of acceptance and integration. Conclusions: The study revealed that a complex array of factors influenced the integration of persons living with a physical disability in post-conflict Bosnia and Herzegovina. Persons with disability indicated the need for individuals and disability groups to collectively advocate for all PWDs in order to voice their goals for integration and social participation. Knowledge, inclusion, participation, and access to health care, education, livelihood, attitude, social participation and advocacy emerged as intrinsic to the successful community integration of persons living with a physical disability. / Thesis (Master, Rehabilitation Science) -- Queen's University, 2011-04-24 13:30:35.306

A determinação do módulo resiliente é realizada através de ensaios triaxiais dinâmicos em equipamentos capazes de aplicar carregamentos cíclicos e de curta duração, que demandam sistemas automáticos de controle e monitoramento e aquisição de dados dos ensaios. Em conseqüência, alguns trabalhos têm procurado estabelecer relações que permitam estimar o módulo resiliente a partir de ensaios mais simples, tais como o CBR e a compressão não confinada. Assim, é importante conhecer a influência da variação da energia de compactação e do teor de umidade em correlações deste tipo. Neste trabalho foram realizados ensaios para a determinação do CBR, resistência à compressão não confinada e módulo resiliente em três solos da Zona da Mata Norte de Minas Gerais, compactados nas energias de compactação do Proctor Normal, Proctor Intermediário e Proctor Modificado, nos teores de umidade Wot – 2 %, Wot e Wot + 2 %. Foram utilizados os modelos bilinear e potencial para correlacionar o módulo resiliente com a tensão desvio. Da análise dos resultados foram estabelecidas relações entre o CBR, a resistência à compressão não confinada, o módulo de elasticidade secante a 50 % da tensão de ruptura e o módulo resiliente para vários níveis de carregamento. Na maioria dos casos, essas relações estão associadas a um dado estado de tensão. Os resultados experimentais evidenciam que não é possível estabelecer uma relação única entre tais parâmetros de resistência e deformabilidade para explicar o efeito da variação da energia de compactação. Tais relações devem ser analisadas para cada solo em particular. As evidências experimentais indicam que a energia de compactação exerce grande influência, mas este efeito varia com o nível de tensão, teor de umidade e tipo de solo. Este estudo deve ser estendido para outros solos regionais, de modo a validar as correlações obtidas e ampliar o seu campo de aplicação. / The resilient modulus is an important parameter to design and analysis of flexible road pavement subject to traffic loading. The assessment of resilient modulus is done through dynamic triaxial tests carried out using testing apparatus able to apply cyclic loading in a short period of time, which requires full automated control and data acquisition systems. As a result, many authors have been proposing the development of correlations to estimate the resilient modulus from simple strength tests such as the unconfined compression and CBR. Therefore, it is important to determine the influence of changes in compaction effort and optimum content in such correlations. In this work, determination of CBR, unconfined compression strength and resilient modulus were carried out for three regional soils of Viçosa - Minas Gerais, compacted with water contents of Wot – 2 %, Wot , and Wot + 2 %, and using Normal, Intermediary and Modified Proctor compaction efforts. The variation of resilient modulus with deviatoric stress was studied using bilinear and potential models. Test results were used to develop equations in order to correlate CBR, unconfined compression strength, E50 and resilient modulus, considering different states of stress. Most of these relationships are related to a specific state of stress. Analysis of test results shows that it is not possible to develop a unique relationship for these parameters with the variation of compaction effort. Therefore, such correlations should be studied for each soil. In addition, test data show that compaction effort exerts a significant influence, but such effect is stress level, water content and soil type dependent. This study should be extended to other regional soils in order to validate the developed correlations as well as to broad their practical applications.

No entanto, apesar de alguns trabalhos publicados, esse método de investigação carece de mais pesquisas, principalmente correlacionando-o a ensaios clássicos, em que se pretenda, além de consolidar seus conceitos, buscar maior confiabilidade na sua utilização. Assim, neste trabalho, com a contribuição de algumas empresas da Região Metropolitana da Grande Vitória, no Espírito Santo, foram realizados ensaios de laboratório e de campo com objetivo de confrontar o PDL com outros ensaios. Em laboratório, com amostras de solos moldadas em cilindros metálicos, foram realizados os ensaios PDL, Cone Penetration Test Adaptado (CPTAD), Califórnia Bearing Ratio (CBR) e cisalhamento direto em dois materiais com caraterísticas distintas, para que a resistência de ponta do ensaio PDL pudesse ser confrontada e correlacionada com a resistência de ponta do CPTAD, Índice de suporte Califórnia e ângulo de atrito. As análises desses resultados consideraram diferentes condições de umidade e densidade dos solos. Para o levantamento em campo, realizaram-se campanhas de ensaios em áreas experimentais com características de solo selecionadas, onde foram executados os ensaios PDL e Standard Penetration Test (SPT), com locação dos furos devidamente aproximados. Os resultados foram correlacionados por meio de equações obtidas de regressões estatísticas. Em laboratório, a resistência de ponta do PDL apresentou resultados similares ao ensaio CPTAD e uma correlação muito boa com o CBR. Quanto ao cisalhamento direto, a pesquisa limitou-se pelo pequeno número de amostras, porém, apresentou compatibilidade razoável entre o PDL e o ângulo de atrito. Já os resultados de campo do PDL e SPT apresentaram boa concordância em alguns casos e nem tão boa em outros. Palavras-chave: Ensaios penetrométricos, Penetrômetro, PDL, CPT, SPT, CBR.

Case-Based Reasoning (CBR) has been successfully applied to many fields especially in the design domain. Poor assembly part design increases the cost, raises the manufacturing complexity and reduces the product quality. However, little research has been devoted to predict the potential design problems in the early design stage. The objective of this paper is to integrate the indexes of assemblability and manufacturability into adaptive phase in CBR to avoid inexperienced mistakes. Early experimental results indicate that quantitative feedback of these indexes can guide novices to depict a good assembly part design, let experienced designers confirm their experience judgments and finally impart the experience to novices through CBR methodology.
