1. Simulation of diets for dairy goats and growing doelings using nonlinear optimization procedures
ABSTRACT The objective of this study was to simulate total dry matter intake and cost of diets optimized by nonlinear programming to meet the nutritional requirements of dairy does and growing doelings. The mathematical model was programmed in a Microsoft Excel(r) spreadsheet. Increasing values of body mass and average daily weight gain for growing doelings

3. Modelagem estocástica de neurônios e sua interação em tempo real com neurônios biológicos / Stochastic neural modelling and interfacing neurons and models in real-time
We developed a mathematical model of the electrical activity of a motor neuron from the stomatogastric ganglion of crustaceans. It was inspired on a previous existing deterministic model which is considered as electrophysiologically plausible in the recent literature. However, this deterministic model were not able to reproduce the irregular bursting behavio

4. Experimental development and mathematical simulation of the photochemically initiated methyl methacrylate pre-polymerization process. / Desenvolvimento experimental e simulação matemática do processo de pré-polimerização fotoiniciada do metacrilato de metila (MMA).
The aim of this work is the experimental optimization, the mathematical modeling and the simulation of the photochemically initiated pre-polymerization process of methyl methacrylate (MMA). According to the industrial interests a pre-polymer of narrow molecular weight distribution (MWD) and defined weight concentration was pointed as an optimum since it impr

5. Despacho economico em usinas hidreletricas
This work s main proposal is to increase the knowledge about mathematical models on hydro-plants optimizations. It is based on the economic dispatch and predispatch models, according to a new approach that inc1udes a representation of each turbine/generator set. The first part treats the relationship between the turbine generators operation variables, in ord

6. Aplicação da modelagem matematica na definição integral da solidificação para projeto ou reprogramação de sistemas de fundição
In this work a three dimensional mathematical model was developed which permifs the integral analysis of the solidification process, as well as the necessary computer tools for practical applications. The model predictions were compared to experimental results obtained in the university laboratories, as well as in foundry industries and a good agreement was
