3. Avaliação econômica e simulação em sistemas agroflorestais / Economic evaluation and simulation in agroforestry system
The general objective of this work was to analyse the economic viability of agroforestry systems using simulation attempting to identify the benefits and the aspects to be improved in them. Specifically, the plan was to survey the production costs of agroforestry system projects; to effect the financial analysis of these systems; and to effect the analyses o

4. VOLTAGE STABILITY PROBABILISTIC ASSESSMENT IN COMPOSITE GENERATION AND TRANSMISSION SYSTEMS / ANÁLISE PROBABILÍSTICA DA ESTABILIDADE DE TENSÃO EM SISTEMAS COMPOSTOS DE GERAÇÃO E TRANSMISSÃO
In some countries, the electric power systems are operating near to their limits due to the absence of investments in the transmission network expansion and natural growth of the electricity demand. This operation condition can also occur in electric power systems in which the transmission expansion is carried out in appropriate way. In this case, the excess

5. Análise de investimento em cana-de-açúcar irrigada no noroeste mineiro / Economic analysis of irrigated sugar cane in Minas Gerais’ northwest
The increasing demand of sugar and alcohol, the sugar cane main products, both in domestic and international market, is causing the expansion of sugar cane fields all over the country. Due to the lack of available land in São Paulo, the most important sugar cane producer, other states, like Minas Gerais, are amplifying sugar cane fields. The northwest of th

6. JustificaÃÃo de investimentos em tecnologias avanÃadas de manufatura: um framework para a avaliaÃÃo da opÃÃo de esperar, sob a Ãtica das opÃÃes reais
Evaluating capital investment projects for the adoption of advanced manufacturing technologies (AMT) is a critical task faced by manufacturing managers. Due to the normally high levels of risk and uncertainty involved, the traditional investment appraisal techniques are often insufficient and must be complemented by sophisticated evaluation methods. Since th

7. Solução de problemas de otimização utilizando arquitetura híbrida. / Solution of optimization problems using hybrid architecture.
Electrical power could be considered as one of the economy propulsion vector of a country, assuming extremely important and strategic role because it makes direct influence to the production capacity. The expansion of electrical energy production could not only be done in a short time because constructions in this area take many years and could require more

8. Dinâmica do uso dos recursos hídricos nas bacias do ribeirão Entre Ribeiros e do rio Preto, afluentes do rio Paracatu / Water resources use dynamics in watersheds of Ribeirão Entre Ribeiros and Rio Preto, tributaries of the Paracatu River
From times past, humanity confronts problems of environmental degradation. The environment, which always performed efficiently its function of filtration, today finds itself excessively overburdened by human activities: it suffers the risk of its resources exhausting, not being able in certain situations to recuperate itself and needing the help of man. Howe

9. Evaluation and selection method for discrete event simulation software dedicated to the analysis of logistic systems. / Método para avaliação e seleção de softwares de simulação de eventos discretos aplicados à análise de sistemas logísticos.
The discrete event simulation is one of the most powerful tools available for modeling and problem analysis. Frequently it is used for planning, designing and controlling complex systems in several segments. The logistic system area has also applied it extensively to analyse the logistic capacities, evaluate the impacts of changes in the productive processes

10. Automatic dependent surveillance on air traffic control: risk assessment based on fluid stochastic Petri nets modeling. / Vigilância dependente automática no controle de tráfego aéreo: avaliação de risco baseada em modelagem em redes de Petri fluidas e estocásticas.
In last decades, the safety critical systems paradigm has changing to adapt itself to new necessities, such as costs reduction and productivity demand growth. In the Air Traffic System, those changes are ruled by CNS/ATM paradigm (Communication, Navigation, Surveillance / Air Traffic Management), based on new digital Technologies, mainly Satellites, applied

11. Risk analysis of the airborne time-based spacing operation through a stochastically and dinamiclly coloured Petri net model. / Análise de risco da operação de espaçamento temporal aerotransportado por meio de um modelo em rede de Petri estocástica e dinamicamente colorida.
The safety in the airspace can considerably increase with the use of airborne spacing and separation operations. Under this paradigm, the task of maintaining a safe distance between aircraft is delegated to the pilots, which will be supported by the Airborne Separation Assistance System (ASAS). With this system, which is still in experimental phase, pilots b

12. Modelo computacional para determinação do risco econômico em culturas irrigadas / Computational model for economical risk determination in irrigated cultures
The agricultural companies were submitted to risky conditions, so the utility of deterministic models to planning is relatively limited. That implies in not despise the randomness of some coefficients and to introduce them in the project analysis. As a proposal of this work a Computational model for risk determination in irrigated cultures was elaborated for
