1. Effect of the Fiber Orientation Relatively to the Plasma Flow Direction in the Ablation Process of a Carbon-Phenolic Composite
ABSTRACT: Composite materials are vastly employed in rocket nozzle extensions and as thermal protection shields in aerospace industry. In both cases, ablative and thermal properties play an important role for material choice and equipment sizing. These properties are strongly dependent on the way the pieces are manufactured. For the case of nozzle extensions

2. Geração distribuída aplicada à edificações : edifícios de energia zero e o caso do laboratório de ensino da FEC-Unicamp / Distributed generation applied to buildings : net zero energy buildings and the case of the laboratory at FEC-Unicamp
Electricity consumption in Brazil increased 47% in the last decade, and it is estimated that it will increase 55.6% until 2020. Most of the electricity generated in the country is based on large hydroelectric dams, located away from the major cities. The planned expansion of the generation park to meet this increase in the demand is also based on this model,

3. Análise de sistemas complexos de drenagem urbana. / Urban drainage complex systems analysis.
This thesis aims to analyze urban drainage complex systems in order to define a technique for the design of detention ponds structures. In this study, Urban Drainage Complex Systems are those composed of several detention ponds, distributed in a network of channels formed by various reaches. This type of system is typical in megacities. The design of the res

6. Dimensionamento ótimo de sistemas híbridos, com geração fotovoltaica e célula a combustível, para atendimento a comunidades isoladas na Amazônia / Optimal design of a hybrid photovoltaic and fuel cell power generation system, to supply isolated communities in the Brazilian Amazon.
The lack of electricity in isolated communities in the Brazilian Amazon has become one of the greatest barriers for the development of the region. Currently, the main technologies that provide electricity to these communities are diesel generators, batteries and dry cells. These non-renewable energy sources may pose serious problems to the environment and hu

7. A fly-by-wire rudder control system design using multiobjective optimization.
This work aims to demonstrate an approach to design a fly-by-wire mobile surface control system for a commercial jet employing multiobjective optimization techniques. This approach consists on sizing a set of design parameters of the control system based on model simulation and response analysis coupled with optimization algorithms in a multiobjective design

8. Gestão de estoques de produtos siderúrgicos semi-acabados utilizando uma abordagem híbrida de otimização e simulação
The inventory management is a vital subject witch frequently absorbs substantial part of the budget of an organization. As they do not add value to the product, as less inventories a productive system use more efficient it will be. However the current competitive environment, with the strong presence of global payers, forces the operational costs reduction,

10. Caracterização e dimensionamento de um sistema de cabotagem industrial. / Characterization and sizing of a industrial short sea system.
Surgiu em 2003 no Brasil uma modalidade de transporte aquaviário, destinada à movimentação de madeira na costa do país, cuja frota de embarcações navega entre dois portos, geralmente com carga em um sentido e vazio em outro. Esta modalidade permite a operação com um pequeno tempo de parada nos portos, operando com poucas interrupções e movimentand

12. Use of discrete event simulation to the sizing of the harvest and transportation of sugar cane fleet. / Uso de simulação de eventos discretos para o dimensionamento de frota para colheita e transporte de cana-de-açúcar.
A produção brasileira de cana-de-açúcar foi de cerca de 426 milhões de toneladas na safra 2006/2007, tendo o estado de São Paulo participado com aproximadamente 264 milhões desse total. Esses valores conferem ao país a posição de maior produtor mundial de cana-de-açúcar, comprovando a importância do setor sucroalcooleiro na economia brasileira.
