O gás natural desempenha papel interessante em diversas matrizes energéticas mundiais e pode-se dizer que o mesmo ocorre no Brasil, onde os problemas relacionados ao racionamento de energia elétrica, levaram à opção pelo produto que, entre outras características, apresenta custo viável e baixos índices de poluição atmosférica, principalmente emissão de monóxido de carbono (CO), um dos elementos de destaque na discussão de questões ambientais / Abstract: The main objective of this work is the assessment of the perspectives of the natural gas (NG) as an alternative fuel to the national market, and according to the possibilities synthesize the estimates of his growth. Nowadays the natural gas is an important piece in several energetic matrices around the world and is possible to say that the same happens in Brazil, where the problems related to the electricity supply suggests the option for the product that presents viable cost and low indexes of atmospheric pollution, mainly carbon monoxide emission (CO), one of the prominence elements in the discussion of environmental subjects / Mestrado / Mestre em Planejamento de Sistemas Energéticos

[pt] Este trabalho faz uma introdução básica aos temas Cadeias de Markov e Matriz de Leontief visando mostrar aplicações práticas de sistemas lineares e matrizes com foco na aplicação no Ensino Médio brasileiro. Para tal, revisou-se as bases teóricas necessárias para o aluno ser capaz de entender e resolver problemas com estes temas. Em complemento, apresenta-se uma proposta de introdução à álgebra linear com geometria analítica, assim como a forma de cobrança da álgebra linear em concursos militares no Brasil. Com o uso de vídeos e ferramentas online, criando caminhos mais amistosos em assunto tão teórico, demonstra-se como o Youtube pode ser uma ferramenta poderosa na visualização de problemas abstratos envolvendo a álgebra linear. / [en] This work makes a basic introduction to the themes Markov Chains and Leontief Matrix aiming to show practical applications of linear systems and matrices with a focus on its application in Brazilian High School. To achieve this goal, the theoretical bases necessary for the student to be able to understand and solve problems with these themes has been revised. In addition, we present a proposal to introduce linear algebra with analytical geometry, as well as the way of taking linear algebra in military tests in Brazil. With the use of videos and online tools and creating friendlier paths on such a theoretical theme, it is demonstrated how Youtube can be a powerful tool in visualizing abstract problems involving linear algebra.

The main objective of this thesis is the definition of tourism supply and demand of tourism to the region Bystřice Pernštejnem. The demand for the region is established on the basis of the survey. The first sub-goal is to evaluate the impact of tourism on the budget of municipalities. In this first part is carried out field research among the mayors of municipalities in the region on their perceptions of tourism. Evaluation of the impact of tourism is carried out on the town budget Bystřice Pernštejnem.First discussed are the revenues, expenditures, and finally the overall impact. Part of this section are evaluated impacts on employment and value of tourist activities found in the region. The second sub-goal is to assess the impact of subsidies on production in the region. This section compares the projects in the field of tourism and other projects on the basis of the calculated gross value added of these observed effects support. The last sub-goal is to determine the multiplier of tourism. Part of this section is a national regionalization symmetric input-output tables for the region SO ORP Bystřice Pernštejnem. Based on the tables are compiled using the technical coefficients matrix, Leontief inverse matrix and matrix Leontieofovi input multipliers calculated for each economic activity. Consequently, expenditure of tourists found the overall multiplier of tourism for the region Bystřice Pernštejnem spending tourists and the impact on production in the region.
