13. Modelagem matemÃtica com simulaÃÃo computacional na aprendizagem de funÃÃes
This research investigated mathematics modeling as an approach to learn the concept of affine, quadratic and exponential functions, on activities of building computer simulations. Our concerns were to identify mathematical and computational abilities mobilized while students use function knowledge on modeling simulations. This led us to search tools to the r

17. UMA APLICAÇÃO DE ALGORITMOS DE COLÔNIAS DE FORMIGAS EM PROBLEMAS DE ROTEIRIZAÇÃO DE VEÍCULOS COM JANELAS DE TEMPO / AN APPLICATION OF ANT COLONY ALGORITHMS TO VEHICLE ROUTING PROBLEMS WITH TIME WINDOWS
Many advances in science were achieved from the observation of nature. Thousands of years of natural selection and evolution made certain living beings develop notable abilities and characteristics, that still nowadays surprise us with their complexity and adaptability. Some fields of science make constant use of intensive observation of these characteristic

18. Development and applications of three-dimensional gamma ray tomography system using ray casting volume rendering techniques
Computed Tomography (CT) has made possible visualization of physical structures in the interior of an object in their real relative spatial position and orientation. Another important contribution of CT is to greatly improve abilities to distinguish regions with different gamma ray transmittance and to separate over-lying structures. The mathematical problem

21. The children difficulties with division: an intervention study / As dificuldades das crianÃas com a divisÃo: um estudo de intervenÃÃo
Children encounter difficulties in dealing with the division concepts. Researches on cognitive psychology and on mathematical education approaches pointed to, between others, two types of difficulties on this area: (a) the difficulty to understand the inverse relations between the division terms while the dividend is held constant, and (b) the difficulty to

22. Analysis of concrete material through gamma ray computerized tomography
Computerized Tomography (CT) refers to the cross sectional imaging of an object from both transmission or reflection data collected by illuminating the object from many different directions. The most important contribution of CT is to greatly improve abilities to distinguish regions with different gamma ray transmittance and to separate over-lying structures
