Повний текст джерелаIn order to improve the performance of adaptive filters, the combination of algorithms is receiving much attention in the literature. This method combines linearly the outputs of two filters operating in parallel with different step-sizes to obtain an adaptive filter with fast convergence and reduced excess mean squared error (EMSE). In this context, it was proposed an affine combination of two least-mean square (LMS) filters, whose mixing parameter is not restricted to the interval [0, 1]. Hence, the affine combination is a generalization of the convex combination. In this work, the affine combination of two LMS algorithms is extended to the supervised algorithms NLMS (normalized LMS) and RLS (recursive least squares), and also to blind equalization, using the constant modulus algorithm (CMA). A steady-state analysis of the affine combination of the considered algorithms is presented in a unified manner, assuming white or colored inputs, and stationary or nonstationary environments. Through the analysis, it was observed that the affine combination of two algorithms of the same family can provide a 3 dB EMSE gain in relation to its best component filter and consequently in relation to the convex combination. To ensure that the combined estimate is at least as good as the best of the component filters, three new algorithms to adapt the mixing parameter were proposed and analyzed. Using the analysis results of these algorithms in conjunction with the results of the transient analysis of adaptive filters, the transient behavior of the affine combination was analyzed. Through simulations, a good agreement between analytical and experimental results was always observed. In the blind equalization case, a combination of two CMA equalizers with different initializations was also proposed. The simulation results suggest that the affine combination can avoid local minima of the constant modulus cost function.

Повний текст джерелаIn this work we study the geometry of the affine evolute and the affine normal curve associated with a plane curve without inflections from the type of singularity of affine support functions. The main result is setting if \'\\gamma\' is a flat curve without inflections, satisfying certain conditions generic then, if p is a point of the affine evolute of \'\\gamma\' at \'s IND. 0\' then two cases: if \'\\gamma\' (\'s IND. 0\') is a sextactic point then locally in p the affine evolute is diffeomorphic to a cusp at \'R POT. 2\', otherwise locally in p the affine evolute is diffeomorphic to a straight in \'R POT. 2\', and second if p = \'\\gamma\' (\'s IND. 0\') is a point of the affine normal curve then two cases: if \'\\gamma\'(\'s IND. 0\') is a parabolic point of \'\\gamma\' then locally in p the affine normal curve is diffeomorphic to a cusp at \'R POT. 2\' , in otherwise locally in p the affine normal curve is diffeomorphic to a line in \'R POT. 2\'

Повний текст джерелаThis Thesis deals with the Cox Process when its intensity belongs to a family of affine diffusions. The form of the probability density function of the Cox process is obtained when the density is described by an arbitrary d-dimensional affine diffusion. Coupling and convergence results are also addressed for a general Cox process with affine intensity. We adopted the Feller diffusion for driving the underlying intensity of the Cox Process to illustrate our results. Additionally the parameters of the underlying intensity processes are estimated by means of the Kalman Filter in conjunction with Quasi-Maximum Likelihood estimation.

Повний текст джерелаEste trabalho investiga a técnica mais natural para a visualização de superfícies implícitas, o raycasting, sob um tratamento intervalar. São implementados algoritmos robustos para o raycasting de superfícies genéricas, utilizando métodos intervalares e métodos numéricos convencionais no cálculo das interseções, e é testada a utilização de aritmética afim (AA), um modelo numérico para o cálculo com intervalos proposto como alternativa à aritmética intervalar tradicional (IA). Projetada para evitar o problema de explosão de erro em longas seqüências de cálculos intervalares, AA leva em consideração as correlações entre os termos de uma expressão e define operações mais caras que IA, mas fornece resultados mais precisos, o que pode acelerar alguns algoritmos intervalares.

Повний текст джерелаThe extended affine TKK Lie algebras belong to a class of Lie algebras called extended affine Lie algebras of type $A_1$. They are obtained from a semilattice on $\\mathbbR^n$. We studied the structure of the Verma type modules for the extended affine TKK algebra obtained from a semi-lattice (non-lattice) on $\\mathbbR^2$. Fixing a set of positive isotropic roots called standard we found four orbits of the Borel subalgebra each of which give distinct Verma modules for the extended affine TKK algebra. We studied the structures of their submodules and found a criteria for irreducibility for the classic and imaginary Verma modules.

Atomic force microscopy (AFM) has been a powerful instrument that provides nanoscale imaging of surface features, mainly of rigid metal or ceramic surfaces that can be insulators as well as conductors. Since it has been demonstrated that AFM could be used in aqueous environment such as in water or various buffers from which physiological condition can be maintained, the scope of the application of this imaging technique has been expanded to soft biological materials. In addition, the main usage of AFM has been to image the material and provide the shape of surface, which has also been diversified to molecular-recognition imaging - functional force imaging through force spectroscopy and modification of AFM cantilevers. By immobilizing of certain molecules at the end of AFM cantilever, specific molecules or functionalities can be detected by the combination of intrinsic feature of AFM and chemical modification technique of AFM cantilever. The surface molecule that is complementary to the molecule at the end of AFM probe can be investigated via specificity of molecule-molecule interaction.
(cont.) Thus, this AFM cantilever chemistry, or chemical functionalization of AFM cantilever for the purpose of chemomechanical surface characterization, can be considered as an infinite source of applications important to understanding biological materials and material interactions. This thesis is mainly focused on three parts: (1) AFM cantilever chemistry that introduces specific protocols in details such as adsorption method, gold chemistry, and silicon nitride cantilever modification; (2) validation of cantilever chemistry such as X-ray photoelectron spectroscopy (XPS), AFM blocking experiment, and fluorescence microscopy, through which various AFM cantilever chemistry is verified; and (3) application of cantilever chemistry, especially toward the potential of force spectroscopy and the imaging of biological material surfaces.

The objective of this work was to verify the difficulties of treatments and conversions (natural language, algebraic expressions, tables and graphical form) function of teaching-learning in order to students of the first high school grade of a private school in the city Sorocaba - SP. The study was conducted by means of tasks implemented in three stages; a group of twenty-six students, divided into thirteen doubles. Therefore, we took care to put to task steps, different forms of representation. The theoretical framework was marked in the study of semiotic representation registers, developed by Raymond Duval, and exploratory and investigative tasks, which served also based on the proposal to diversify the methodological procedures used in the teaching function in order. The written production analysis of research subjects sought answer how students of the first high school series have mobilized and coordinated semiotic representation registers in solving exploratory-investigative tasks involving the concept of affine function? The articulation of exploratory-investigative tasks, with the mobilization and coordination of semiotic representation registers, instigated the students to the process of generalization of the concept and characterization of affine function through the use of natural language record in the form of justification.

O objetivo desta dissertação foi verificar as dificuldades de tratamentos e conversões (língua natural, expressões algébricas, tabelas e forma gráfica) de ensino-aprendizagem da função afim aos alunos da primeira série do Ensino Médio de uma escola particular na cidade Sorocaba - SP. O trabalho foi desenvolvido, por meio de tarefas aplicadas em três etapas; junto a uma turma com vinte e seis alunos, divididos em treze duplas. Para tanto, tomou-se o cuidado de se colocar nas etapas das tarefas, diferentes formas de representação. O referencial teórico foi pautado no estudo dos registros de representação semiótica, desenvolvido por Raymond Duval, e das tarefas exploratório-investigativas, as quais serviram também de base na proposta de se diversificar os procedimentos metodológicos utilizados no ensino de função afim. A análise da produção escrita dos sujeitos da pesquisa buscou responder; Como alunos da primeira série do Ensino Médio mobilizaram e coordenaram registros de representação semiótica na solução de tarefas exploratórias-investigativas envolvendo o conceito de função afim? A articulação das tarefas exploratórias-investigativas com a mobilização e coordenação dos registros de representação semiótica instigaram os alunos ao processo de generalização do conceito e caracterização da função afim, por meio do uso do registro da língua natural na forma de justificativas.

Повний текст джерелаA presente pesquisa tem como objetivo geral investigar possibilidades de situações de aprendizado da Matemática de conceitos relativos às funções polinomiais do 1º grau (Função Afim) com alunos da 1ª série do Ensino Técnico de Nível Médio Integrado do IFS Campus São Cristóvão fazendo uso de uma Sequência Didática mediada pelo uso de um software de geometria dinâmica, o GeoGebra. Para tanto, foi realizado um estudo, pautado nas ideias de Machado (2008), Pais (2011) e Oliveira (2013), embasados na Engenharia Didática discutida por Artigue (1996) com duas turmas da 1ª Série do curso Técnico de Nível Médio Integrado do Instituto Federal de Educação, Ciência e Tecnologia de Sergipe Campus São Cristóvão/SE, que formaram os grupos de estudo que denominamos de Grupo com o experimento (GCE) e Grupo sem o experimento (GSE). Ao término da experiência ficou constatado que o GCE apresentou melhores resultados do que o GSE. Os dados indicaram que utilizar um software de geometria dinâmica em um ambiente de geometria dinâmica proporciona uma grande interação entre os participantes constituindo um fator positivo ao aprendizado, uma vez que facilitam a construção de novos conceitos, proporcionam a comparação entre as diferentes formas de representação de uma função, possibilitando, assim, condições para o participante de reconhecer a representação gráfica de uma função polinomial do primeiro grau como uma reta, expressar a relação entre os coeficientes da equação da reta com sua representação gráfica e algébrica.

Повний текст джерелаNesta dissertação de mestrado, nós desenvolvemos um processo de litografia baseado na técnica de microscopia de força atômica. O estudo do processo de litografia aqui utilizado inicia-se com a deposição e caracterização de filmes finos de sulfeto de arsênio amorfo (a-As2S3) em substratos de silício e a deposição de uma camada metálica de alumínio, utilizada como máscara, sobre a superfície do a-As2S3. O microscópio de força atômica é utilizado para escrever os padrões de forma controlada na camada metálica, e para tal, a influencia dos parâmetros de controle do microscópio na realização da litografia foi analisada. Para a transferência do padrão litografado realiza-se um posterior processo de fotossensibilização e dissolução química do a-As2S3 com uma solução de K2CO3. Após a dissolução, uma camada de ouro foi depositada por erosão catódica DC, seguido de uma nova dissolução, desta vez com NaOH resultando na transferência de nanoestruturas de Au para o substrato de silício.
In this dissertation, we have developed a lithography process based on the atomic force microscopy of technique. The study of the lithography process starts with the deposition and characterization of amorphous arsenic sulfide thin films (a-As2S3) in silicon substrates and the deposition of a metallic aluminum layer, used as mask, on the surface of the a-As2S3. An atomic force microscope was used to write patterns in a controlled way on the metallic layer. Therefore, the influence of microscope feedback system on the accomplishment of the lithography was analyzed. In order to transfer the lithographed pattern to a silicon substrate, the a- As2S3 was exposed to a UV light source and was dissolved with a K2CO3 solution. Then, a thin gold layer was deposited by sputtering DC, and a new dissolution, now with NaOH was performed, leading to the deposition of Au nanostructures onto the silicon substrate.

According to[8] and [6], it is the same as to apply the localization technique to the first realization of free fields of A(1)1.To achieve the purpose, we introduced the Kac-Moody algebras, having the main focus the af-fine Kac-Moody algebras, according to [14]. Following, we defined the Verma modules, highlighting imaginary Verma modules of affine Lie algebra A(1)1, according to [8].

In the preliminary studies held, mainly, in the bibliographic review, it was observed that many essays show learning difficulties that students from different levels of education have regarding the study of the affine function. Wanting to broaden the studies held before to this respect and aware that the theme still needs research, it was considered by hypothesis for this study that a teaching sequence conceived to the light of the Theory of Didactic Situations and to the Theory of Semiotics Representation Registers, mediated by the use of a software of dynamic geometry, the Geogebra, it might contribute for an indication to the study of the affine function. The purpose of this research was to develop a teaching sequence to start the study with 9th graders that contributed to the development of the capability of expressing algebraically and graphically the dependence of the two variants from an affine function and acknowledge that its graphical representation is a straight line, relating the coefficients from the straight line equation with the graphic. After the elaboration, the a priori analysis of the sequence and the application in the 9th grade of a private school from the Great São Paulo, the a posteriori analysis showed that our hypothesis was confirmed, this means, that a sequence developed and applied based on the Theory of Didactic Situations and on the register change of the representation leads 9th graders to acknowledge that the graphic of an affine function is a straight line and the majority to express algebraically and graphically the relation between the two variants of an affine function, besides relating the straight line equation coefficients to the graphical representation of the affine function
Nos estudos preliminares realizados, sobretudo, na revisão bibliográfica, observou-se que muitos trabalhos constatam dificuldades de aprendizagem que alunos de diferentes níveis de escolaridade apresentam em relação ao estudo da função afim. Com intuito de ampliar os estudos já realizados a esse respeito e conscientes de que o tema ainda carece de pesquisas, considerou-se por hipótese deste estudo que uma sequência de ensino concebida à luz da Teoria das Situações Didáticas e da Teoria dos Registros de Representações Semióticas, mediada pelo uso de um software de geometria dinâmica, o Geogebra, poderá contribuir para uma iniciação ao estudo da função afim. O objetivo da pesquisa foi desenvolver uma sequência de ensino para iniciar o estudo com alunos do 9º ano do Ensino Fundamental que contribuísse para o desenvolvimento da capacidade de expressar algébrica e graficamente a dependência de duas variáveis de uma função afim e reconhecer que seu gráfico é uma reta, relacionando os coeficientes da equação da reta com o gráfico. Após a elaboração, a análise a priori da sequência e a aplicação na turma de 9º ano do E.F. de uma escola particular da Grande São Paulo, a análise a posteriori mostrou que nossa hipótese foi confirmada, isto é, que uma sequência desenvolvida e aplicada com base na Teoria das Situações Didáticas e na mudança de registros de representação conduz alunos do 9º ano a reconhecer que o gráfico de uma função afim é uma reta e a maioria a expressar algébrica e graficamente a relação entre duas variáveis de uma função afim, além de relacionar os coeficientes da equação da reta com a representação gráfica da função afim

Повний текст джерелаThe main goal of this dissertation is to describe a proposal for teaching affine functions to first year classes of the third education cycle (equivalent to seventh grade of elementary school), through the application of Mathematical Modeling inserted on a research scenario and understood as a learning environment. It also aims to determine the pertinence of working the referred subject with students from the involved age group. The class under analysis was, during the time of the proposal deployment, part of the Elementary City School, located in the city of Porto Alegre, Brazil. Concerning the theoretical framework, the study was primarily substantiated on the concepts of Mathematical Modeling, as defined by Barbosa (2001), Biembengut (2000) and Skovsmose (2000). The methodology chosen for the research process was the case study. For the model development, the work with the students was based on a research about cell phone plans offered by mobile operators from the state of Rio Grande do Sul, with the goal of finding out which one of them offers the most advantageous proposal, according to the customer’s needs. During the meetings, transitions among learning environments as defined by Skovsmose (2000), as well as among different cases as proposed by Barbosa (2001) took place. The students’ performance during classes and their results obtained at the end of the sequence of activities demonstrated that the implemented proposal is valid and proper for the age group under analysis, and that through Mathematical Modeling there is a better comprehension of the Mathematic subjects involved in the work. As a final product, there is still the material developed during the course of work, which can be used in the future for teachers who desire to make use of similar activities in their classes.

ENGLISH ABSTRACT: Planar weak link structures, such as micro-bridges, variable thickness bridges and nanobridges, have always attracted a lot of attention. Their potential to behave as real Josephson elements make them useful devices, with numerous applications. Powerful techniques, such as focused ion-beam and electron-beam lithography, were successfully used and are well understood in planar weak link structure fabrication. In this dissertation the results of an experimental study on planar weak link structures are presented. For the first time these structures have been successfully fabricated using AFM nanolithography on hard high-temperature superconducting YBCO tracks, where diamond coated silicon tips were used as a ploughing tool. Superconducting YBCO thin films were deposited on different substrates, using inverted cylindrical magnetron sputtering. The films were used to fabricate micro-bridges, variable thickness bridges and nano-bridges, by using conventional photolithography, argon ion-beam milling and AFM nanolithography. The measured I-V characteristics of the fabricated micro-bridges (width down to 1.9 µm), variable thickness bridges (thickness down to 15 nm) and nano-bridge (width down to 490 nm) showed well defined DC and AC Josephson effect characteristics. For better understanding of the behaviour of these types of weak links, critical current versus temperature measurements, and magnetic field modulation of the critical current measurements, were also performed, with the results and discussions given inside the chapters. The major challenges that were experienced in the laboratory during the fabrication processes and the operation of the fabricated devices are also discussed, with the solutions given where appropriate.
AFRIKAANSE OPSOMMING: Swak-skakel vlakstrukture, soos mikrobr.ue, br.ue met veranderlike dikte en nanobr.ue, het nog altyd baie aandag getrek. Hul het die potensiaal om soos werklike Josephson-elemente te kan funksioneer en is, as gevolg hiervan, nuttige toestelle met veelvuldige toepassings. Kragtige tegnieke, soos gefokuste ioonstraal- en elektronstraal litografie, is suksesvol gebruik en word goed verstaan in die vervaardiging van swak-skakel vlakstrukture. In hierdie proefskrif word die resultate van ¡¦n eksperimentele studie van swak-skakel vlakstrukture voorgel.e. Vir die eerste keer is hierdie strukture suksesvol vervaardig, deur gebruik te maak AFMnanolitografie op harde, ho¡Le-temperatuur supergeleier YBCO (Yttrium Barium Koperoksied) spore, waar diamantbedekte silikonpunte gebruik is as ploeginstrument. ¡¦n Dun lagie van supergeleidende YBCO is op verskillende substrate gedeponeer, deur gebruik te maak van omgekeerde silindriese magnetron verstuiwing. Die dun lagies is gebruik in die vervaardiging van mikrobr.ue, br.ue met veranderlike dikte en nanobr.ue, deur die gebruik van gewone fotolitografie, argon-ioonstraal frees en AFM nanolitografie. Die gemete I-V eienskappe van die vervaardigde mikrobr.ue (met breedte so laag as 1.9 µm), veranderlike-dikte br.ue (dikte tot 15 nm) en nanobr.ue (breedte so min as 490 nm) toon goed gedefinieerde GS en WS eienskappe van die Josephson-effek. Ten einde die gedrag van hierdie tipes swak-skakels beter te kan verstaan, is metings gedoen van kritieke stroom teenoor temperatuur, asook magnetiese veld modulasie van die kritieke stroom. Hierdie resultate en besprekings daarvan word binne die toepaslike hoofstukke aangebied. Die grootste uitdagings wat in die laboratorium, sowel as met die toetsing van die vervaardigde toestelle ondervind is, word ook bespreek. Waar moontlik, word toepaslike oplossings voorgestel.

This paper presents a new way of discussing concepts involving function, a ne function and quadratic function. Through simple activities with the use of blocks of cubes, and the multiplane software such as GeoGebra, students will move from a passive position, as simple listener, the active member of the teaching-learning process, enabling them to acquire a broader notion the concept of function and apply it later in solving problems in school and in their daily lives. Besides these diversi ed activities, topics that are usually not given prominence in most books of high school such that the analysis of the canonical form of the quadratic function and the theorem of characterization of a ne function will play an important role in developing what is expected of students about this important area of mathematics. All activities were conducted with 1st grade students of high school Natalicia Maria Figueiroa da Silva, located in the city of Surubim, in the state of Pernambuco.
Este trabalho apresenta uma nova maneira de se discutir conceitos envolvendo função, função a m e função quadrática. Através de atividades simples com uso dos blocos de cubos, do multiplano e de softwares como o Geogebra, o aluno passará de uma posição passiva, como simples ouvinte, a integrante ativo do processo de ensino-aprendizagem, possibilitando ao mesmo adquirir uma noção mais ampla do conceito de função e aplicá- lo posteriormente na resolução de problemas na escola e em sua vida cotidiana. Além dessas atividades diversi cadas, tópicos que geralmente não são colocados em destaque na maioria dos livros de ensino médio tais quais a análise da forma canônica da função quadrática e o Teorema de caracterização da função a m terão um importante papel no desenvolvimento que se espera dos estudantes a respeito dessa importante área da Matemática. Todas as atividades foram desenvolvidas com alunos da 1a série do ensino médio da Escola Estadual Natalícia Maria Figueiroa da Silva, localizada na cidade de Surubim no Estado de Pernambuco.

Повний текст джерелаIn this paper, the a.ne connection approach will be defined in terms of a local transformation. Accordingly, the macroscopic anisotropy of the nematic medium will be conceived as resulting from a local transformation where, at each point of the sample, the spherical molecules of an idealized hypothetic isotropic liquid have their shape changed to the ellipsoidal form of the nematic liquid crystals molecules. When such a local character is imposed to this transformation, the patterns determined by the director configuration of the nematic medium acquire an intrinsic curvature whose correct treatment requires the replacement of the techniques and methods of the usual calculus by those of the di.erential geometry of non-flat surfaces. Such approach will be used in the calculus of the nematic elastic constants. As a result, the dependence of the elastic constants on the scalar order parameter, on the eccentricity of the nematic molecules and on the interaction between them will be determined and compared with the experimental data.
