Previous issue date: 2005 / Resumo: No presente trabalho se realiza o estudo e desenvolvimento de um modelo numérico computacional com a finalidade da simulação de sistemas de refrigeração por compressão de vapor. Em um primeiro momento, foram analisados e discutidos os principais tipos de modelamento para cada componente do sistema de refrigeração (compressor, condensador, válvula de expansão e evaporador) encontrados na literatura. Após esta primeira análise, foram escolhidos os modelos utilizados para o desenvolvimento do programa computacional. O programa foi validado a partir da comparação dos resultados obtidos numericamente com os obtidos em ensaios experimentais. Após a validação, foram feitos dois estudos de casos, para a verificação da influência dos parâmetros sobre os sistemas simulados e otimização do desempenho de tais sistemas / Abstract: This work performs the study and development of a numerical computational model in order to simulate refrigeration systems by steam compression. At first, the main types of modelation for each component of the refrigeration system (compressor, condenser, expansion valve and evaporator) found in literature are analysed and discussed. After this first analysis, the models for the development of a computational program are chosen. The program is validated by means of the comparison of the results obtained numerically with those acquired in experimental tests. Just after validation, two studies of cases are made to verify the influence of the parameters on the simulated systems and to optimize the performance of those systems / Mestrado / Termica e Fluidos / Mestre em Engenharia Mecânica

"MRAKODRAP" - architektonická studie výškové stavby u Právnické fakulty Masarykovy univerzity v Brně / "SKYSCRAPERS" - the architectural study of high-rise buildings near the Faculty of Law at Masaryk University in BrnoIrber, Tomáš January 2010 (has links)
In this diploma thesis, I have tried to design a high-rise building in Brno and offer new opportunities for built-up areas in a manner that respects the future of urban development. I have applied the principles of nature patterns on the very structure of the building and thus I have reached the perfection of nature, which in my view offers an elegant, simple and already proven solution.

Aplikace matematických znalostí při výuce biologieSTUDENÁ, Lucie January 2018 (has links)
The Theses deals with applications of mathematical knowledge in teaching biology and it is divided into four chapters. Each chapter is dedicated to another application: 1. Application of conditional probability in medical diagnostics, 2. Application of exponential function in population ecology, 3. Application of logic functions in mathematical modelation of neuron and 4. Aplication of binomial theorem and binomial distribution in genetics. Each application contains solved problems, a worksheet for students and a solution for each worksheet. Two application (1. and 2.) have been tested in teaching and as an assessment of my lessons students filled questionnaires. Results of these questionnaires are processed in the end of these chapters. This Thesis can be used in teaching or self-studying.
