1. Invariantes Operatórios de Equilíbrio Algébrico Presentes nas Estratégias de Estudantes do 3° Ano do Ensino Fundamental
Resumo Em vários países, têm sido recorrentes relatos de dificuldades de entendimento de conceitos algébricos. A solução para este problema, proposta por grande parte da comunidade de educadores matemáticos pelo mundo, foi promover a introdução de conceitos algébricos desde os primeiros anos escolares. O objetivo deste trabalho foi descrever e anal

2. Pensamiento Aritmético-Algebraico a través de un Espacio de Trabajo Matemático en un Ambiente de Papel, Lápiz y Tecnología en la Escuela Secundaria
Abstract In this paper, we want to address the problem of teaching algebra from the point of view of the theoretical framework of Mathematical Working Spaces (MWS). In our study, we carried out two experiments, one in Quebec and one in Mexico. In this research, we consider the visualization has started, once the individual communicates his ideas to others (o

3. Finite volume simulation of 2-D steady square lid driven cavity flow at high reynolds numbers
In this work, computer simulation results of steady incompressible flow in a 2-D square lid-driven cavity up to Reynolds number (Re) 65000 are presented and compared with those of earlier studies. The governing flow equations are solved by using the finite volume approach. Quadratic upstream interpolation for convective kinematics (QUICK) is used for the app

4. On the evaluation of linear and non-linear models using DNS data of turbulent channel flows
In this paper, a priori and a posteriori analyses of algebraic linear and non-linear models are carried out in order to compare their ability to predict near wall turbulent flows. Tests were done using data from a direct numerical simulation (DNS) of a plane channel flow for three Reynolds numbers, based on the friction velocity, Reτ = 180, Reτ = 395 and R

5. Some properties of deformed q-numbers
Nonextensive statistical mechanics has been a source of investigation in mathematical structures such as deformed algebraic structures. In this work, we present some consequences of q-operations on the construction of q-numbers for all numerical sets. Based on such a construction, we present a new product that distributes over the q-sum. Finally, we present

6. Teoria algébrica de números e o grupo de Galois / The Galois group of de x POT.n- x POT. n-1 - ...x-1
Nessa dissertação provamos que se n é um inteiro par ou primo, então o Grupo de Galois de x POT.n- x POT.n - 1"...- x - 1 é o grupo simétrico S IND.n. Essa família de polinômios surge naturalmente de uma generalização da sequência de Fibonacci

7. Interger fatorization and groups on conics / Fatoração de inteiros e grupos sobre conicas
The objective of this paper is to factorize integer number using rational points on the unitary circle. Also, it intends to determinate some groups on the conics. The research begins with the basic concepts of Algebra and Number Theory ensuring that the rational points set on the unitary circle has a structure of group. From this set is possible to extend th

8. The Interval Constructor on classes of ML-algebras
Monoidal logic, ML for short, which formalized the fuzzy logics of continuous t-norms and their residua, has arisen great interest, since it has been applied to fuzzy mathematics, artificial intelligence, and other areas. It is clear that fuzzy logics basically try to represent imperfect or fuzzy information aiming to model the natural human reasoning. On th

10. Dynamic simulation of flash drums using rigorous physical property calculations
The dynamics of flash drums is simulated using a formulation adequate for phase modeling with equations of state (EOS). The energy and mass balances are written as differential equations for the internal energy and the number of moles of each species. The algebraic equations of the model, solved at each time step, are those of a flash with specified internal

11. Arithmetic fuchsian groups identified in quaternion orders for the construction of signal constellations / Grupos fuchsianos aritmeticos identificados em ordens dos quaternios para construção de constelações de sinais
Within the context of digital communications system in homogeneous space in particular, in hyperbolic spaces, it is necessary to establish systematic procedure for the construction of lattices O ; as the basic entity for construction of eometrically uniforms signal constellations. By this procedure we identify the algebraic and geometric structures to constr

12. 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
