1. Modelos modificados de redes neurais morfológicas / Modified models of morphological neural networks
Morphological neural networks (MNN) are artificial neural networks whose hidden neurons perform elementary operations of mathematical morphology (MM). Several particular models of MNNs have been proposed in recent years, including morphological perceptrons (MPs), morphological perceptrons with dendrites, (fuzzy) morphological associative memories, modular mo

2. A formação de professoras para o ensino de ciencias nas series iniciais : analise dos efeitos de uma proposta inovadora / The formation of teachers for teaching Sciences in elementary school : analysis of the effects of an innovative proposal
The research objective is to analyze the effects caused by an innovative proposal of formation in services, for the conceptions and practices declared by the polyvalent professors who teach Science in the elementary school. The professors who participated in the research studied Education at Unicamp, thanks to an agreement between the University and the Muni

3. A difícil aceitação dos números negativos: um estudo da teoria dos números de Peter Barlow (1776-1862)
The present study seeks to present a historico-epistemological analysis of the development of the mathematical concept of negative number. In order to do so, we analyzed the different forms and conditions of the construction of mathematical knowledge in different mathematical communities and, thus, identified the characteristics in the establishment of this

4. Problemas de comportamento do aluno na visão de professores da rede pública de São Paulo
This study aims to identify the criteria used by teachers in the public school system to characterize behavioral problems of students because along with the problems being constantly mentioned by many teachers, a number of stereotypes have been created to explain behavior that falls outside the expectations of public schools. These stereotypes are designated

5. As Equações Diofantinas Lineares e o Professor de Matemática do Ensino Médio
Neste trabalho apresento um estudo qualitativo sobre se, e como, professores de Matemática do Ensino Médio trabalham com seus alunos situações-problema que recaem em equações diofantinas lineares. O estudo foi feito por meio da análise de entrevistas semi-estruturadas realizadas com seis professores de Matemática dos estados de São Paulo e Minas Ger

6. Re-significando a disciplina teoria dos números na formação do professor de matemática na licenciatura
This study is part of the issue that questions which algebra should be taught in the different levels of schooling, especially in the development of mathematics teachers for basic education. In this context, this study was guided by the question: Which Number Theory is or should be understood as a piece of knowledge to be taught in mathematics teacher develo

7. O desafio do desenvolvimento profissional docente: análise da formação continuada de um grupo de professoras das séries iniciais do ensino fundamental, tendo como objeto de discussão o processo de ensino e aprendizagem das frações
This study it has as objective to analyze factors that can intervene with the professional development of teachers of the first series of Elementary School, as resulted of a formation continued with the purpose to argue questions related to the boarding of the fractionary representation of rational numbers and its different meanings. For the collection of da

8. The linear diophantine equations and the mathematics textbook for high school / As equações diofantinas lineares e o livro didático de matemática para o ensino médio
This work involves a qualitative study of how the theme of linear Diophantine equations is approached in mathematics textbooks for high school students. Using the methods associated with content analysis (Bardin, 1977), I search for references, in both explicit and implicit forms, to these equations in two different sets of high school mathematics textbooks,

9. O uso de material concreto com representaÃÃes retangulares na construÃÃo do conceito de decomposiÃÃo multiplicativa
This study aims to investigate the effects of using of manipulatives that explore rectangular representations of multiplication to appropriate the concept of multiplicative decomposition of natural numbers by 5th grade students of elementary school. The use of manipulatives was investigated on the basis of the theory of didactic situations, developed by Guy

10. Incorporação da teoria de matriz densidade no metodo Monte Carlo Quantico aplicado na obtenção de potenciais de ionização de valencia e de caroço / Incorporation of the density matrix theory in the Quantum Monte Carlo method applied in the calculation of valence and core ionization potentials
Quantum Monte Carlo (MCQ) is an stochastic method that makes possible to solve the Schrödinger equation. The two most common approachs are: the variational Monte Carlo (MCV) and diffusion Monte Carlo (MCD). The implementation of MCQ presented close results to the experimental values for a great number of systems. However, it does not represent excited state

11. NÃmeros decimais: no que os saberes de adultos diferem dos de crianÃas?
The study compared adultsâ and childrenâs knowledge of decimal number. It examined the differences between adultsâ and childrenâs learning processes and how practical knowledge affects studentsâ performance. Several studies have researched decimal number because of its apparent complexity to learners, for example; Porto, 1995; Lerner, 1995; Irwin, 1995;

12. Divisão de números naturais: concepções de alunos de 6 série
This research was carried out with 28 students from the 6 th grade of Elementary School and it aims to detect their conceptions about division of Natural Numbers. It investigates three questions: a) do they know techniques division?; b) do they know how to work with division as a tool to solve problems? c) which relations do they establish involving the term
