13. Relações de referencia e aplicações / Recurrent relations and applications
This study is about Recurrence Relations and some of their methods of resolution. We tried to generate an easy-to-read-text which stimulates the reader to proceed and to deepen his study about this subject. Three resolution methods with their theorems and demonstrations were studied: the method for first order recurrences, the characteristic root method and

14. Elementos finitos com resolução simplificada de sistemas de equações lineares para dispositivos fotônicos / Finite elements with simplified solutions of linear systems of equations for photonic devices
The Finite Element Method is one of the most popular numerical tools in electromagnetics. Implicit schemes require the solution of sparse linear equation systems, this step demands a lot of computational time. This work proposes alternatives enhancements to obtain better computational performance of such implicit schemes. This was made through the improvemen

15. Linguagens de domínio específico e sensores baseados em modelos biológicos de computação
A Domain Specific Language is a specification language dedicated to a particular domain, representation technique, or solution searching method. On the other hand, a general-purpose programming language is a language designed with the goal of emulating Lambda Calculus or Turing Machine. Since general-purpose languages must accept any algorithm that can be ex

16. UMA DISCIPLINA, UMA HISTÓRIA: CÁLCULO NA LICENCIATURA EM MATEMÁTICA DA UNIVERSIDADE FEDERAL DE SERGIPE (1972-1990)
The present work has the intention to construct a history of discipline Calculation in the course of Degree in Mathematics of the Federal University of Sergipe, during the period from 1972 to 1990. It examines the historical curse of discipline by means of the workload, of the prerequisite ones, of its contents, its professors and methods of teaching. It ana

17. Surface spectral analysis and applications in computer graphics / Analise espectral de superficies e aplicações em computação grafica
Em computação gráfica, diversos problemas consistem na análise e manipulação da geometria de superfícies. O operador Laplace-Beltrami apresenta autovalores e autofunções que caracterizam a geometria de variedades, proporcionando poderosas ferramentas para o processamento geométrico. Nesta dissertação, revisamos as propriedades espectrais do opera

18. Numeros de entropia de conjuntos de funções suaves sobre a esfera S POT. d / Entropy numbers of sets of smooth functions on the sphere S POT. d
The entropy theory was introduced by Kolmogorov around 1930. Since then, many works aims to find estimates for entropy numbers of certain classes of sets. The main objective of this work is to study two theorems that establishes upper and lower estimates for entropy numbers of generic multiplier operators. To prove these theorems, we utilize some results on

19. THE TEACHERS TRAINING CONTRIBUTES TO INCREASE STUDENTS LEARNING?: A STUDY OF THE RELATIONSHIP BETWEEN TEACHER QUALIFICATION AND THE PERFORMANCE OF STUDENTS IN ELEMENTARY SCHOOL / A CAPACITAÇÃO DE PROFESSORES CONTRIBUI PARA A APRENDIZAGEM DOS ALUNOS?: UM ESTUDO DAS RELAÇÕES ENTRE QUALIFICAÇÃO DOCENTE E MELHORIA DE DESEMPENHO DE ESTUDANTES NO ENSINO FUNDAMENTAL
This research sought to identify if the increase in average proficiency of pupils in basic education in the State of Tocantins occurred between the years 2001 to 2007 could be explained by improved qualification of Mathematics and Portuguese teachers who participated in training activities promoted by the Cesgranrio Foundation in the years of study. The rela

20. Uma trajetória hipotética de aprendizagem sobre funções logarítmicas
This work has as objective, contribute to the reflection about an important moment in the process of curriculum implementation, in other words, the one which is developed inside of the classroom, analyzing how its plan can be done and where is the teacher related to this process. It has as a theoretician recital the Simons works about hypothetical trajectori

21. Modelagem matemática e semiótica : algumas relações
Neste trabalho, apresentamos uma pesquisa fundamentada nos pressupostos teóricos da Modelagem Matemática na perspectiva da Educação Matemática e procuramos estabelecer relações entre esta perspectiva e a Semiótica de Peirce e a Teoria dos Registros de Representação Semiótica de Raymond Duval. Para tanto, analisamos três atividades de Modelagem Ma

22. Desempenho Escolar em Pernambuco: AnÃlise dos Itens e das Habilidades usando Teoria ClÃssica e TRI
Since 1980âs, the Item Response theory (IRT) has been very important subject among measurement experts due to applications in several fields including education. In this work, an introduction of that theory is presented and applied to item analysis in high school exams. Using IRT, hability estimates were obtained from 2005 SAEPE data analysis of Portuguese

23. A dinamica por tras da sequencia espectral / The dynamic behind the spectral sequence
In this work, we present an algorithm for a chain complex C and its di_erential given by a connection matrix which determines an associated spectral sequence (Er, dr). More specifically, a system spanning Er in terms of the original basis of C is obtained as well as the identi_cation of all di_erentials dr p : Er p ! Er p?r. In exploring the dynamical implic
