1. FUZZY MODELING OF SALINITY EFFECTS ON RADISH YIELD UNDER REUSE WATER IRRIGATION
ABSTRACT The increase of water usage for food production in recent years has triggered researches on ways to optimize the use of water and to reuse saline water. The present study analyzes the effects of reused saline water in the irrigation of radish culture and the construction of a fuzzy logical mathematic model so that producers may evaluate their produc

3. Modelagem matemática na previsão de colheita de bananeira: regressão linear múltipla x redes neurais artificiais / Mathematical modeling to predict crop of banana: multiple regression x neural networks
One of the barriers relevant to the banana crop in Brazil is the lack of productive commercial varieties with adequate size, resistant to major pests and diseases and adapted to different ecosystems. The development of cultivars is the strategy for solving this problem through breeding programs, as well as its characterization and evaluation in areas of prod

5. MODELAGEM INDIVIDUAL E EM TEMPO REAL DAS EXIGÊNCIAS NUTRICIONAIS DE SUÍNOS EM CRESCIMENTO / MODELING INDIVIDUAL AND IN REAL TIME OF THE NUTRIENT REQUIREMENTS FOR GROWTH PIGS
Two studies were realized with the objective (i) to describe and to establish the limitations of the empirical and factorial methods used to estimate nutritional requirements and (ii) develop a mathematic model able to estimate the daily nutrient requirements of individual pigs in real time. For this purpose, in the first study a systematic analysis was carr

7. Modelagem e anÃlise de especificaÃÃes de sistemas de tempo-real crÃticos com restriÃÃes de energia
Requirements analysis is a critical task in any Embedded Real-Time System (ERTS) project. Normally, these systems have stringent timing constraints that must be satisÂed for the correct functioning, since violation might be catastrophic, such as loss of human lives or large amount of Ânancial resources. In addition, there are systems where energy is anothe

8. Services allocation in a metrology laboratory using genetic algorithms / Distribuição de serviços em laboratório de metrologia utilizando algoritmos genéticos
As simple as it might look, the problem of allocating a group of tasks to be executed with a limited number of available machines will always present a number of details and restrictions that in certain cases can result in a solution of great complexity. Some of the variables involved are: service priority, available raw materials, machinery or equipment cap

9. Análise crítica da utilização de modelagem matemática na avaliação da dispersão de efluentes leves no litoral da Baixada Santista ( Estado de São Paulo). / The analysis of mathematical models in the assessment of effuents dispersion in Baixada Santista coastline (State of São Paulo).
The prediction of the hydrodynamic water circulation and pollutants dispersion, mainly in coastal areas, has been a problem that engineers have been facing. This is due to the increase environmental impacts that involve coastal engineering work and management. The usage of mathematic modeling as assessment tool is necessary for these studies. The main purpos
