Previous issue date: 2014-11-19 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / This work goal to show a possible relationship between the Golden Ratio with nature,
animals, architecture, music and also as a motivation to study mathematics content,
such as: ratio, proportion and arithmetic average, making the teaching learning more
enjoyable. The realization of it proceeded from the literature and field research. The
literature describes the history of the Golden Mean and the Fibonacci ratio with the
Golden Ratio. The Fibonacci sequence was known for the problem of pairs of rabbits
(coniculorum Paia) that is found in the book Liber Abacci (Liber Abaci). Also
highlights the relationship between the golden ratio and the nature, proposing that it
can be widely used in daily life of the student, promoting a differentiated learning.
The field research was the application of the proposed activities presented
throughout the study in a rural school of the Federal District, with the purpose to
promote the recognition that it is possible to understand the relationship between
math and everyday living. Initially the diagnosis 1 (ATTACHMENT A), containing
socio-cultural issues and also the diagnosis 2 (ATTACHMENT B) containing specific
questions of reason, proportion, arithmetic mean and golden ratio was applied. After
applying the diagnosis twelve o'clock classes were taught using contextualized and
interdisciplinary methodologies where activities (ATTACHMENT C, D, E, F) were
applied seeking to respond to the objectives of this study. In closing the interventions
took place applying the same initial diagnosis in order to determine whether
interventions have provided new results. In analyzing the results of the second
application of diagnosis was realized a significant increase in students' understanding
about the content worked. The results show that when there is an understanding of
the relationship between mathematics learning and everyday life, students can define
new knowledge and relate school learning and their daily lives, which facilitates
learning. / Este trabalho tem por objetivo, mostrar uma possível relação da Razão Áurea com a
natureza, os animais, a arquitetura, a música e também como motivação ao estudo
de conteúdos de Matemática, tais como: razão, proporção e média aritmética,
tornando o ensino-aprendizagem mais prazeroso. A realização do mesmo procedeu
a partir da pesquisa bibliográfica e de campo. A pesquisa bibliográfica descreve a
história do Número de Ouro e a relação da Sequência de Fibonacci com a Razão
Áurea. A Sequência de Fibonacci ficou conhecida pelo problema dos pares de
coelhos (paia coniculorum) que é encontrado no livro Liber Abacci (Líber Ábacos).
Destaca ainda a relação entre a razão áurea e a natureza, propondo-se que esta
pode ser amplamente utilizada no cotidiano do discente, buscando promover uma
melhor aprendizagem. A pesquisa de campo consistiu na aplicação das atividades
propostas apresentadas ao longo do estudo em uma escola da zona rural do Distrito
Federal, tendo como fim promover o reconhecimento de que é possível
compreender a relação entre o ensino de matemática e a vivência cotidiana.
Inicialmente foi aplicado o diagnóstico 1 (ANEXO A), contendo questões
socioculturais e também o diagnóstico 2 (ANEXO B) contendo questões específicas
de razão, proporção, média aritmética e razão áurea. Após a aplicação do
diagnóstico foram ministradas doze aulas utilizando-se metodologias
contextualizadas e interdisciplinares em que foram aplicadas atividades (ANEXO C,
D, E, F) buscando responder aos objetivos deste estudo. Ao encerrar as
intervenções realizou-se a aplicação do mesmo diagnóstico inicial com o intuito de
averiguar se as intervenções propiciaram novos resultados. Na análise dos
resultados da segunda aplicação do diagnóstico foi percebido um aumento
significativo na compreensão dos discentes em relação ao conteúdo trabalhado. Os
resultados evidenciam que quando há uma compreensão da relação entre
aprendizagem matemática e a vida cotidiana, os discentes conseguem delimitar
novos saberes e relacionar a aprendizagem escolar e sua vivência diária, o que
facilita a aprendizagem.

Previous issue date: 2018-03-16 / Conselho Nacional de Pesquisa e Desenvolvimento Científico e Tecnológico - CNPq / Let $ k \geq 2.$ an integer. The recurrence $ \fk{n} = \sum_ {i = 0}^k \fk{n-i} $ for $ n> k $, with initial conditions $F_{-(k-2)}^{(k)}=F_{-(k-3)}^{(k)}=\cdots=F_{0}^{(k)}=0$ and $F_1^{ (k)} = 1$, which is called the $k$-generalized Fibonacci sequence. When $ k = 2 ,$ we have the Fibonacci sequence $ \{ F_n \}_{n\geq 0}.$ We will show that the equation $F_{n}^{x}+F_{n+1}^x=F_{m}$ does not have no non-trivial integer solutions $ (n, m, x) $ to $ x> 2 $. On the other hand, for $ k \geq 3,$ we will show that the diophantine equation $\epi$ does not have integer solutions $ (n, m, k, x) $ with $ x \geq 2 $. In both cases, we will use initially Matveev's Theorem, for linear forms in logarithms and the reduction method due to Dujella and Pethö, to limit the variables $ n, \; m $ and $ x $ at intervals where the problem is computable. In addition, in the case for $ k\geq 3 $, we will use the fact that the dominant root the $k$-generalized Fibonacci sequence is exponentially close to 2 to bound $k$, a method developed by Bravo and Luca. / Seja $k\geq 2$ inteiro, considere-se a recorrência $\fk{n}=\sum_{i=0}^{k}\fk{n-i}$ para $n>k$, com condições iniciais $F_{-(k-2)}^{(k)}=F_{-(k-3)}^{(k)}=\cdots=F_{0}^{(k)}=0$ e $F_{1}^{(k)}=1$, que é a sequência de Fibonacci $k$-generalizada.
No caso quando $k=2$, é dizer, para a sequência de Fibonacci $\{F_n\}_{n\geq 0}$, vai-se mostrar que a equação $F_{n}^{x}+F_{n+1}^x=F_{m}$ não possui soluções inteiras não triviais $(n,m,x)$ para $x>2$. Por outro lado para, $k\geq 3$ se mostrar que a equação diofantina $\epi$ não possui soluções inteiras $(n,m,k,x)$ com $x\geq 2$. Em ambos casos, inicialmente são usados resultados como o Teorema de Matveev, para formas lineares em logaritmos e o método de redução de Dujella e Pethö, para limitar as variáveis $n, \; m$ e $x$ em intervalos onde o problema seja computável. Adicionalmente, no caso para $k\geq 3$ é usado que a raiz dominante da sequência de Fibonacci $k$-generalizada e exponencialmente próxima a 2, para limitar $k$, o que é um método desenvolvido por Bravo e Luca.

Ana Carolina Boero / Dissertação (mestrado) - Universidade Federal do ABC, Programa de Pós-Graduação em Mestrado Profissional em Matemática em Rede Nacional, 2017. / A Razão Áurea possui uma longa história e atualmente é muito mistificada. Nesse trabalho, são apresentadas relações matemáticas e propriedades da Razão Áurea e da Sequência de Fibonacci, sendo constatado que se tratam apenas de casos particulares que podem ser obtidos através de uma recorrência linear de segunda ordem homogênea de onde surge um conjunto de números irracionais com características semelhantes.
Foram mostradas, ainda, possibilidades de atividades que de fato contemplam a Razão Áurea e a Sequência de Fibonacci e os cuidados necessários com informações equivocadas e manipuladas. / The Golden Ratio has a long story and currently it¿s very mystified. In this paper, mathematical relations and properties of the Golden Ratio and the Fibonacci Sequence are introduced, stating that they are only particular cases, which can be obtained through a second homogeneous order linear recurrence from where comes a set of irrational numbers with similar characteristics. We explained, as well, possibilities of activities that actually contemplate the Golden Ratio and the Fibonacci Sequence, and the necessary cares with wrong and manipulated information.

Some Applications Of Integer Sequences In Digital Signal Processing And Their Implications On Performance And ArchitectureArulalan, M R 01 1900 (has links) (PDF)
Contemporary research in digital signal processing (DSP) is focused on issues of computational complexity, very high data rate and large quantum of data. Thus, the success in newer applications and areas hinge on handling these issues. Conventional ways to address these challenges are to develop newer structures like Multirate signal processing, Multiple Input Multiple Output(MIMO), bandpass sampling, compressed domain sensing etc. In the implementation domain, the approach is to look at floating point over fixed point representation and / or longer wordlength etc., related to number representations and computations. Of these, a simple approach is to look at number representation, perhaps with a simple integer. This automatically guarantees accuracy and zero quantization error as well as longer wordlength. Thus, it is necessary and interesting to explore viable DSP alternatives that can reduce complexity and yet match the required performance. The main aim of this work is to highlight the importance, use and analysis of integer sequences. Firstly, the thesis explores the use of integer sequences as windowing functions. The results of these investigations show that integer sequences and their convolution, indeed, outperform many of the classical real valued window functions in terms of mainlobe width, sidelobe attenuation etc. Secondly, the thesis proposes techniques to approximate discrete Gaussian distribution using integer sequences. The key idea is to convolve symmetrized integer sequences and examine the resulting profiles. These profiles are found to approximate discrete Gaussian distribution with a mean square error of the order of 10−8 or less. While looking at integer sequences to approximate discrete Gaussian, Fibonacci sequence was found to exhibit some interesting properties. The third part of the thesis proves certain fascinating optimal probabilistic limit properties (mean and variance) of Fibonacci sequence. The thesis also provides complete generalization of these properties to probability distributions generated by second order linear recurrence relation with integer coefficients and any kth order linear recurrence relation with unit coefficients. In addition to the above, the thesis also throws light on possible architectural implications of using integer sequences in DSP applications and ideas for further exploration.

ON GENERATING THE PROBABILITY MASS FUNCTION USING FIBONACCI POWER SERIESAmanuel, Meron January 2022 (has links)
This thesis will focus on generating the probability mass function using Fibonacci sequenceas the coefficient of the power series. The discrete probability, named Fibonacci distribution,was formed by taking into consideration the recursive property of the Fibonacci sequence,the radius of convergence of the power series, and additive property of mutually exclusiveevents. This distribution satisfies the requisites of a legitimate probability mass function. It's cumulative distribution function and the moment generating function are then derived and the latter are used to generate moments of the distribution, specifically, the mean and the variance. The characteristics of some convergent sequences generated from the Fibonacci sequenceare found useful in showing that the limiting form of the Fibonacci distribution is a geometricdistribution. Lastly, the paper showcases applications and simulations of the Fibonacci distribution using MATLAB. / <p></p><p></p><p></p>
