1. Solving the inverse scattering problem with differential evolution: an experimental validation
Abstract This work shows the experimental validation of a method developed for determining the strain profile applied to a fiber Bragg grating by solving the inverse scattering problem. The non-uniform strain profile is recovered by formulating an optimization problem, solved with an algorithm based on differential evolution. The method has proved to be able

2. CHOOSING THE OPTIMAL GEL MORPHOLOGY IN ELECTROPHORESIS SEPARATION BY A DIFFERENTIAL EVOLUTION APPROACH (DEA)
Abstract This paper introduces an effective optimization approach to investigate the morphological effects of nanocomposite gel electrophoresis and operational parameters (see below) by integrating the numerical simulations based on finite element method and population-based search algorithm such as differential evolution. Simulations are performed to study

3. A STUDY OF PYROLYSIS OF MACADAMIA NUT SHELL: PARAMETRIC SENSITIVITY ANALYSIS OF THE IPR MODEL
Abstract The macadamia tree is known for producing fruit high in fats, enclosed in very hard woody shells. Macadamia nut shell, considered as a by-product from macadamia nut processing, may be a suitable option for pyrolysis. These residues are constituted of cellulose, hemicellulose, lignin and extractives. The Independent Parallel Reaction (IPR) Model has

4. Otimização da separação sólido-líquido em hidrociclones mediante modificações geométricas
Because of advantages such as low cost, simple structure, large capacity of suspension processing and small dimensions, hydrocyclones are widely used for separating dispersed phase (liquid or solids) from continuous one. The shape and size of a hydrocyclone has a decisive effect on the internal flow structure of the continuous phase, and therefore, the separ

5. Supervision and management almost great hybrid power systems based on differential evolution for the region of the Pantanal / Supervisão e gerenciamento quase ótimo de sistemas híbridos de energia baseado em evolução diferencial para a região do Pantanal
A design of two supervison and management system for hybrid energy systems is proposed in this work, one based on the operator experience, and another using an algorithm of global search called Differential Evolution. The application of these systems is for remote areas in general, but in this work is given focus to isolated areas in the Pantanal region of M

6. Fuzzy logic applied to the modeling of the transfer of water in soils / LÃgica fuzzy aplicada à modelagem da transferÃncia de Ãgua em solos
Modeling water movement in the unsaturated soil requires a great number of parameters and variables such as the initial soil-water content, the saturated soil-water content, and the saturated hydraulic conductivity, which can relatively easily be assessed. Other functions such as hydraulic conductivity and matric potential which are nonlinear functions of th

7. O algoritmo talus na resoluÃÃo do problema do controle Ãtimo
This dissertation aims at proposing a procedure for solving optimum control problems by using the Pontryagin Maximum Principle and probability algorithms, mainly Talus, with a view to improving accuracy and increasing efficiency in this process. The historical development of the optimum control theory is thus presented and the main features of the used algor

8. PDE models associated to fuzzy logic ans statistical methods in the treatment of uncertainties : an application on food-and-mooth disease / Modelos de EDP integrados a logica Fuzzy e metodos probabilisticos no tratamento de incertezas : uma aplicação a febre aftosa em bovinos
The foot-and-mouth disease is a viral, infectum contagious pathology, characterized for a scene full of inherent uncertainties, resultants of the influence of social, economic and environmental factors related to the transmission process, that can occur for direct and indirect means. In Epidemiology, great part of the uncertainties are treated either by the

10. Otimização dinâmica da fermentação alcoólica no processo embatelada alimentada
This work presents an experimental and theoretical study of the dynamic optimization of the alcoholic fermentation in fed-batch mode utilizing the Saccharomyces cerevisiae yeast in a bioreactor of 5 L. Twelve experiments were carried out, three them in batch and nine in fed-batch mode, with initial sucrose concentrations between 154 and 195.6 g/L for the exp

12. Modelo termodinamico para o aquecimento não-linear, a laser, e suas aplicações ao processamento de materiais
The subject of the computer modeling of the laser processing of materials continues to be highly topical in Materials Science. Basic to such an achievement was to have an well posed proposition to determine the time evolution of the temperature anywhere in the laser heated sample. Though models of such a kind abound in the literature, they are either rather
