13. Eletro-oxidação de glicerol sobre eletrodos de platina modificados com hidróxido de cobalto
The increased production of biodiesel has resulted in the overproduction of glycerol that has generated fear of improper disposal, due to low market value of the product and consequent lack of interest. Glycerol, discovered in 1779 by Scheele, is used industrially in the production of over 1500 products such as toiletries, cosmetics, food, beverages and poly

14. Selecting the system most likely to be the best in the presence of an infinite number of alternatives
Simulation Optimization (SO) belongs to a broader class of problems called Stochastic Optimization. Most of the proposed SO methodologies in the literature aim to optimize the expected value of the performance measure. This thesis focus is on another class of problems: Multinomial Selection Procedures (MSPs). These procedures select the best alternative, whe

15. UMA ABORDAGEM OTIMIZADA PARA O PROBLEMA DE ALOCAÇÃO DE EQUIPES E ESCALONAMENTO DE TAREFAS PARA A OBTENÇÃO DE CRONOGRAMAS EFICIENTES / AN OPTIMIZED APPROACH TO THE PROBLEM ALLOCATION OF TEAMS AND SCALING OF TASKS FOR OBTAINING schedules EFFICIENT
In software development, as well as any other activity of a wide range of engineering, an effective project planning is essential. Failures in planning or poor planning can cause delays and costs that, given time and budget constraints, are often unacceptable, leading to critical failures in business. One of the main activities of project planning is the pla

16. Use of response surface methodology to optimization of extraction of enzymes from pineapple pulp.
The enzymatic reactions are very important for food. They are responsíble for the formation of highly desirable cornpound, but can cause disorders and undesirable consequences. The physiological behaviour of vegetables and fruits is already known, so that most of its deterioration changes in flavour, colour and nutritional value are caused by enzymes of the

17. Estudo de algoritmos estocásticos de otimização para avaliação da oxidação de etanol a acetaldeído / Study of stochastic optimization algorithms for the evaluation of oxidation of acetaldehyde
A utilização de rotas verdes para obtenção de químicos é hoje uma área de grande interesse mundial. A necessidade de se desenvolver e estudar processos químicos que sejam, em sua integridade, independentes da via petroquímica são prementes. O etanal (acetaldeído), importante componente em diversos processos químicos, pode ser obtido pela oxidaç�

18. Alocação econômica de recursos naturais no contexto de bacia hidrográfica : aplicação na bacia do rio Sangão em Santa Catarina
The environmental impacts caused by natural resources exploration may cause damages to third parties, since these agents¿ actions harm the environment and, in some cases, make the existence of other activities unfeasible. This context includes coal mining and irrigated rice cropping. Coal mining and beneficiation make possible the contact between water and

19. Otimização da Produção de Enzimas por Aspergillus niger em Fermentação em Estado Sólido
Brazil is one of the main producer countries of rice and passion fruit. The production of these foods have generated a large amount of wastes which could represent serious problems with the final disposal and cause economic losses from misuse of biomass. The enviroment pollution and loss of economic value from this biomass can be reduced by using this materi

20. Use of biomimetic systems at the preparation of amperometric sensors / Utilização de sistemas biomiméticos no Preparo de sensores amperométricos
This work describe the immobilization of the copper(II) dinuclear complex ([Cu2(apyhist)2Cl2](ClO4)2), (apyhist =[(4-imidazolyl)ethylene-2-amino-1-ethylpyridine]), and others similar copper(II) compounds mono- and tetranuclears, obtained in water solution or for desprotonation of the imidazole ligant, in the Nafion membrane on glass carbon electrode surface,

21. Avaliação do glicerol proveniente da fabricação do biodiesel como substrato para produção de endotoxinas por Bacillus thuringiensis var. israelensis / Evaluation of glycerol derived from biodiesel production as substrate for endotoxins production by Bacillus thuringiensis var. israelensis.
The use of glycerol derived from biodiesel production as a substrate for the acquisition of biotechnology products is a promising alternative as an adequate disposal mean of this by-product. The bioinsecticide formulated with toxins from Bacillus thuringiensis has been used to control vectors insects of diseases, such as dengue, which affect millions of peop

22. 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,

23. Um novo método híbrido aplicado à solução de sistemas não-lineares com raízes múltiplas / A new hybrid method applied to the solution of nonlinear systems with multiple roots
This paper aims to present solutions for nonlinear systems with multiple roots, using a hybrid algorithm. For this purpose was developed and implemented an algorithm based on random search method proposed by Luus and Jaakola (1973) as a step in search of random starting points, which will be refined through the algorithm of Hooke and Jeeves. The differential

24. AJUSTE AUTOMÁTICO DE HISTÓRICO EM RESERVATÓRIOS DE PETRÓLEO UTILIZANDO O MÉTODO TSVD / AJUSTE AUTOMÁTICO DE HISTÓRICO EM RESERVATÓRIOS DE PETRÓLEO UTILIZANDO O MÉTODO TSVD
Reservoir simulation is an essential tool extensively used by reservoir engineers. It is mostly employed to predict reservoir behavior under dfferent circumstances, thus supporting decisions that frequently involve large nancial costs. In order to use this tool properly different petro-physical properties of the reservoir must be well known, such as permeabi
