No. of bitstreams: 1 Jéssica Cristina da Sousa Silva.pdf: 3803180 bytes, checksum: 09661347277c0b6b6dadfa09a5e05299 (MD5) Previous issue date: 2017-04-03 / FAPEMA / As a result of a contingency, severe overloads may occur in a power transformer. One of the greatest concerns of energy utilities is to find a way to operate this equipment that ensures its useful life is preserved. However, there is a sharp reduction in the useful life in proportion to the level of overload and this increases the risk of failure. This paper sets out a framework for decision-making in emergency operations for power transformers, that rely on interruption contracts as decision variables and which take into account the risk of accepting any level of violation of the transformer´s operating limits. The risk of failure is calculated by measuring the useful life of the transformer and the presence of dissolved gases. The useful life is estimated by means of the Arrhenius model of thermal damage , while incipient faults can be detected by Dissolved Gas Analysis (DGA). The risk of transformer failure is estimated by examining the data cited above, on the basis of information theory concepts. It is formulated as a multi-period optimization problem with linear objectives and nonlinear constraints and restricted to the risk of accepting transformer overloads. The results are validated by means of an adapted version of the IEEE14 system, which is shown to be effective as a tool for emergency decision-making in the case studies included here. / Como consequência de uma contingência, sobrecargas severas podem ocorrer em transformadores de potência. Uma das maiores preocupações das concessionárias de energia, é operar estes equipamentos de forma que a vida útil seja preservada. No entanto esta diminui drasticamente em proporção ao nível de sobrecarga aplicado além do aumento do risco de falha. Este trabalho apresenta uma estrutura para o auxílio na tomada de decissões de operação em emergência de transformadores de potência, utilizando como variáveis de decisão contratos de interrupção conjugados com a decisão de aceitar um nível de sobrecarga baseado no risco. São usados modelos térmicos de envelhecimento do transformador para cálculo de perda de vida. Para atualização da probabilidade do risco de falha, são utilizadas informações de Análise de Gases Dissolvidos (DGA) e da perda de vida útil do transformador combinadas através de conceitos de teoria da informação. Os resultados são validados usando uma versão adaptada do sistema IEEE 14, mostrado-se eficaz como ferramenta de tomada de decisões nos estudos de caso apresentados.

Investiční životní pojištění / Investment Life Insurance

Tilšerová, Pavlína January 2012 (has links)
The main of the master’s thesis is to determine current opportunities of investment life insurance in the Czech Republic. In the theoretical part of the thesis, the basic concepts of life insurance and investment life insurance are specified. In the practical part, the statistical analysis of insurance market development in the Czech Republic is presented. The work further provides the comparison of investment life insurance products of selected insurance institutions. The comparison is made on the basis of selected parameters and model examples. Conclusions and recommendations of this study could help to everybody participated in pension system and with a focus on modern form of life insurance.

Rizikové faktory související s endometriózou žen v reprodukčním věku, ALSWH studie / Risk factors affecting endometriosis in women of reproductive age, ALSWH Study

Olšarová, Karolína January 2019 (has links)
This thesis adapts a life course approach in epidemiology to endometriosis. Endometriosis is a highly prevalent chronic disease affecting women in reproductive age. Firstly, the topic of this disease is introduced, the situation and current knowledge in Australia is discussed. Positive changes in a national level are presented. Secondly, early life exposers and maternal behaviour are investigated as possible risk and protective factors. A systematic review of early life factors identified a low birthweight and formula feeding of infants as risk factors for the development of endometriosis. Lastly, the relation of birthweight, weight at childhood and endometriosis was analysed using data of Australian Longitudinal Study on Women's Health. Other risk and protective factors were evaluated and included into the analysis. Logistic regression was used for determination of statistical significance. High weight at 10 years old was found to be a protective factor against endometriosis.

As experiências das mulheres abrigadas e as entrevistas realizadas com estas, já desabrigadas, permitiram observar que a referida lei, bem como a sua implementação, não responderam às suas necessidades, sendo que elas, após passarem por audiência, permaneciam com a situação de risco inalterada, e seus maridos/companheiros, continuavam ameaçando-as. No que diz respeito à metodologia, esta pesquisa utilizou os conceitos de gênero e patriarcado, pois acreditamos que um deles, isoladamente, não dá conta da complexidade desta realidade.
