Nosso principal objetivo é a construção de reticulados que são versões rotacioanadas de reticulados já conhecidos na literatura. Deste modo, apresentamos construções obtidas via polinômios, via perturbações do homomorfismo canônico e, também, construções ciclotômicas a partir fo reticulado Zn. / This work presents a study of algebraic and families of ideal lattices. Our main goal is the construction of lattices which are rotated versions of known lattices in the literature. In this way, we present constructions obtained via polynomials, via pertubations of the canonical homomorphism, and also cyclotomic construction from the lattice Zn.

In the 1880s and early 1890s, the Prague mathematician Eduard Weyr published his important results in matrix theory. His works represented the only significant contribution to matrix theory by Czech mathematicians in many decades that followed. Although Eduard Weyr was one of the few European mathematicians acquainted with matrix theory and working in it at that time, his results did not gain recognition for about a century. Eduard Weyr discovered the Weyr characteristic, which is a dual sequence to the better known Segre characteristic, and also the so-called typical form. This canonical form of a matrix is nowadays called the Weyr canonical form. It is permutationally similar to the commonly used Jordan canonical form of the same matrix and it outperforms the Jordan canonical form in some mathematical situations. The Weyr canonical form has become much better known in the last few years and even a monograph dedicated to this topic was published in 2011.

This study starts from the perspective of a future increase availability of water quality data at the water treatment facility at Lovön and aims to use the existing data to identify a pattern in the role of the different sub-basin that constitute the Mälaren basin. The data are analyzed with the graphical tool of the scatterplot and a Non-linear Canonical Correlation Analysis, a variation of the classical multivariate method, that by using a neural network model is able to handle not linear relationships. From the data analysis, it is possible to identify that different areas have different contribution in shaping the water quality at the facility of Lovön, but also that this pattern of contribution is strongly affected by the season inside the analyzed year.

A história da sintaxe dos clíticos do português europeu (PE) revela, de forma evidente, as mudanças sintáticas ao longo do tempo. Por isso, tal sintaxe é considerada um dos maiores indicadores gramaticais, constituindo, assim, uma importante chave da história gramatical do PE. O português europeu contemporâneo é predominantemente enclítico, situação contrária à do século XVI quando era predominantemente proclítico. A datação da mudança da nova gramática dos clíticos, que deixou de ter como norma comum a próclise, fixando em seu lugar a ênclise nas orações nãodependentes cujos verbos não fossem precedidos por: a) operador de negação predicativa; b) quantificador; c) sintagma -qu; d) certos advérbios e; e) sintagma focalizado, é uma questão que ainda não está definida. Assim, examinou-se, nesse corpus, a sintaxe dos clíticos com três objetivos principais, que são: a) analisar a colocação dos clíticos no século XVII, a partir do corpus estabelecido; b) caracterizar o corpus a partir de variáveis sociolingüísticas relevantes para a análise: quem escreveu, quando, onde, para quem e como; c) confrontar os resultados obtidos com os oriundos de análises feitas por outros autores, particularmente, para a mesma sincronia, a fim de encontrar elementos reveladores da sintaxe dos clíticos que contribuam para definição da gramática internalizada pelos falantes do século XVII. Para o alcance desses objetivos, cumpriram-se três etapas de fundamental importância: a) a recolha exaustiva das ocorrências de clíticos no Arte de Cozinha; b) a classificação, inclusive estatística, da ordem (pré-verbal/pós-verbal) em que os clíticos se apresentam nos diversos contextos sintáticos; c) a análise dos resultados obtidos, descrevendo-se o uso dos clíticos na gramática de um autor não-canônico do século XVII. / Salvador

The overall objective was to observe, analyze and relate the popular communication that is part of the process to the consolidation of the miracle worker figure. The culture Theories, especially Folkcommunication, as well as the language, became a relevant referential in the analysis of the communication forms of the devout population and the printed newspapers in Teresina. In order to do this, a combination of methodologies such as the one from Marques de Melo (2008) to inventory the ex-votes, as well as semi structured interviews, collecting testimonies and an observing participation to collect data and sort the information obtained. The analysis revealed that oral communication is the most widely used and has the most influence on the devout population, that the newspapers reproduce the populations stories and that the saint is created and formed in day to day living, family fellowship, neighbors and friends. / Este estudo analisa o processo comunicacional em torno das manifestações populares e da história do santo não-canônico piauiense Motorista Gregório. O objetivo geral consistiu em observar, analisar e relacionar a comunicação popular que faz parte do processo à consolidação da figura do milagreiro. As teorias da cultura, especialmente a Folkcomunicação, assim como as da linguagem, configuraram-se referenciais relevantes nas análises das formas de comunicação dos devotos e dos jornais impressos de Teresina. Para isso, utilizou-se uma combinação de metodologias tais como a de Marques de Melo (2008) para inventariar os ex-votos, além de entrevistas semiestruturadas, coleta de depoimentos e observação participante para reunir dados e classificar as informações obtidas. A análise revelou que a oralidade é a forma de comunicação mais utilizada e que mais tem influencia sobre os devotos, que os jornais impressos reproduzem as histórias do povo e que o santo é criado e formado no cotidiano, no convívio dos familiares, vizinhos e amigos.

Genome-wide associations studies (GWASs) have identified hundreds of loci that are strongly associated with coronary artery disease and its risk factors. However, the causal variants and genes remain unknown for the vast majority of the identified loci. Zebrafish model systems coupled with clustered regularly interspaced short palindromic repeats-C–associated 9 (CRISPR Cas-9) mutagenesis have enabled the possibility to systematically characterize candidate genes in GWAS-identified loci. In this thesis, canonical correlation analysis (CCA) was used to identify putative causal genes in multiplexed genetic screens for atherogenic traits in zebrafish larvae in an efficient manner. The two datasets used in this thesis contained genes and phenotypes obtained through sequencing and high-throughput imaging of fish larvae. Dataset 1 contained (7 genes, 11 phenotypes, n = 384) and dataset 2 (4 genes, 11 phenotypes, n = 384). CCA’s multiple genes vs. multiple phenotype analysis in dataset 1 identified the genes met, pepd, timd4 and vegfa to have an association with the total cholesterol, triglycerides, glucose, corrected lipid disposition, as well as co- localization of (macrophage and lipid deposition,) (neutrophils and lipid deposition) and (macrophage and neutrophils). In dataset 2, CCA found previously reported correlation of genes apobb1 and apoea with total cholesterol, low-density lipoprotein and triglycerides as well as co localization of neutrophils and lipids. In comparison with hierarchical linear model, CCA represents a powerful and promising tool to identify causal genes for cardiovascular diseases in data from zebrafish model systems.

The use of conversational agents has increased across the world. From providing automated support for companies to being virtual psychologists they have moved from an academic curiosity to an application with real world relevance. While many researchers have focused on the content of the dialogue and synthetic speech to give the agents a voice, more recently animating these characters has become a topic of interest. An additional use for character animation technology is in the film and video game industry where having characters animated without needing to pay for expensive labour would save tremendous costs. When animating characters there are many aspects to consider, for example the way they walk. However, to truly assist with communication automated animation needs to duplicate the body language used when speaking. In particular conversational agents are often only an animation of the upper parts of the body, so head motion is one of the keys to a believable agent. While certain linguistic features are obvious, such as nodding to indicate agreement, research has shown that head motion also aids understanding of speech. Additionally head motion often contains emotional cues, prosodic information, and other paralinguistic information. In this thesis we will present our research into synthesising head motion using only recorded speech as input. During this research we collected a large dataset of head motion synchronised with speech, examined evaluation methodology, and developed a synthesis system. Our dataset is one of the larger ones available. From it we present some statistics about head motion in general. Including differences between read speech and story telling speech, and differences between speakers. From this we are able to draw some conclusions as to what type of source data will be the most interesting in head motion research, and if speaker-dependent models are needed for synthesis. In our examination of head motion evaluation methodology we introduce Forced Canonical Correlation Analysis (FCCA). FCCA shows the difference between head motion shaped noise and motion capture better than standard methods for objective evaluation used in the literature. We have shown that for subjective testing it is best practice to use a variation of MUltiple Stimuli with Hidden Reference and Anchor (MUSHRA) based testing, adapted for head motion. Through experimentation we have developed guidelines for the implementation of the test, and the constraints on the length. Finally we present a new system for head motion synthesis. We make use of simple templates of motion, automatically extracted from source data, that are warped to suit the speech features. Our system uses clustering to pick the small motion units, and a combined HMM and GMM based approach for determining the values of warping parameters at synthesis time. This results in highly natural looking motion that outperforms other state of the art systems. Our system requires minimal human intervention and produces believable motion. The key innovates were the new methods for segmenting head motion and creating a process similar to language modelling for synthesising head motion.

Such as theory corresponds to the general relativity, minimally coupled to a massless scalar field, in the frame where the geometry is riemannian. We present the fundamental elements of the Weyl geometry and we extend the hamiltonian formalism of the general relativity to this geometry. We propose a foliation invariant by Weyl transformations, in which the Weyl scalar field plays the role of a clock to measure the evolution of the foliation. Cosmological singularities are verified in the clas­sical solutions of the FLRW model and avoided in the quantum cosmology approach. The Weyl transformations provides a canonical transformations between two related frames and a unitary operator is defined to map these two frame in the quantum regime. The physical equivalence in the quantum level is discussed. / Investigamos a cosmologia de modelos regidos por uma teoria escalar-tensorial geometrica, construida numa geometria de Weyl integravel. Tal teoria corresponde a teoria da Relati­vidade Geral, minimamente acoplada a urn campo escalar sem massa, no referencial onde a geometria é Riemanniana. Apresentamos os elementos fundamentais da geometria de Weyl e estendemos o formalismo hamiltoniano da Relatividade Geral para esta geometria, prepa­rando assim o formalismo para descrever teorias ambientadas na geometria de Weyl. Propo­mos uma folheagao invariante por transformagoes de Weyl, a qual emprega o campo escalar de Weyl, oriundo da geometria, como urn relOgio natural para a evolugao do universo. Singu­laridades cosmolOgicas sao verificadas nas predigoes das solugoes classicas do modelo FLRW e removidas quando tratamos a cosmologia quantica deste modelo. As transformagoes de Weyl sao investigadas no espago de fase, onde induzem transformagoes canonicas que viabilizam a equivalencia fisica entre os referenciais de Riemann e Weyl tanto no regime classic° como no quantico.

The singular analysis reflects on the writer José Condé's absence on the daily routine of reading nowadays. As he is a practically unknown author today, the works begins with the writer's biography presentation and then it makes some inroads in his works as a writer and journalist, based on observations made on his private library. The reflection about the literary canon and some canonical instances tries to find the reasons why Condé's work is sold out in bookstores and publishing houses. Interviews with José Condé's contemporaries, family and friends were made to conduct the research in order to saddle up the writer's widest possible life panel and there were also interviews with people linked to Literature, either in the production of books, holding events or taking part in the composition of Academies. The theoretical reflection is based on Michel de Certeau (2011), Roger Chartier (1998, 1999,2001, 2002, 2007), Robert Darnton (1992, 2010) among others that write about social and economic issues related to the literary support, its implications in the composition and maintenance of the literary canon. Michel Foucault (1992, 2008) was used as the subsidies to reflect on the Power, basic element in the formation of the canon. / Este trabalho consiste numa discussão sobre o cânone literário brasileiro, focando questões acerca do como e por quem é formado, quem o mantém e como é mantido. Singularizamos a análise, refletindo sobre a ausência do escritor José Condé, do cotidiano de leitura atual. Por ser um autor praticamente desconhecido hoje, iniciamos com uma apresentação biográfica do escritor, para, em seguida, realizar algumas incursões em sua atuação como escritor e jornalista, partindo de observações de parte do acervo que compõe sua biblioteca particular. Refletimos sobre o cânone literário e algumas instâncias canônicas, em busca de razões pelas quais a obra de Condé encontra-se esgotada em livrarias e editoras. Para a realização da pesquisa, recorremos a entrevistas com contemporâneos de José Condé, familiares e amigos, a fim de montarmos um painel biobibliográfico mais amplo possível do escritor; entrevistamos igualmente pessoas ligadas à literatura, seja na produção do livro, seja na realização de eventos, seja na composição de academias. Teoricamente, refletimos com Michel de Certeau (2011), Roger Chartier (1998; 1999; 2001; 2002; 2007), Robert Darnton (1992; 2010), entre outros, sobre questões sociais e econômicas ligadas ao suporte literário, suas implicações na composição e manutenção do cânone literário; também buscamos em Michel Foucault (1992; 2008) subsídios para refletir sobre o Poder, elemento basilar na formação do cânone.

Com o objetivo de compreender quais fatores abióticos determinam a ocorrência das diferentes formações florestais na região de Batatais, entre as coordenadas 20038S e 20058S e 47037W e 47028W, foram escolhidas três propriedades agrícolas (Fazenda Monte Belo, em Restinga, SP e Fazenda Magnólia e Sítio Pratinha, em Batatais, SP), que apresentavam remanescentes florestais representativos da região (floresta ribeirinha paludícula, floresta estacional semidecídua ribeirinha e cerradão). Para descrever a composição florística e a estrutura da comunidade arbórea foram amostradas 05 parcelas de 10 x 10 m ao redor de cada estação tensiométrica. Para o estudo dos fatores abióticos foram determinados os parâmetros físicos e químicos dos solos e as curvas de retenção de água nos solos e piezometria. A discriminação das variáveis abióticas e de vegetação foi feita através da análise de componentes principais (PCA) e, na correlação entre a abundância de espécies e fatores abióticos, foram feitas análises diretas de gradiente por meio de Análise de Correlação Canônica (CCA). A textura dos solos (teores de argila, silte e areia) e a posição no terreno (cota), foram as variáveis ambientais mais importantes na distribuição das espécies e nas variações das fisionomias florestais, com influência na retenção hídrica e nos índices de fertilidade dos solos. Essas diferenças nos teores de argila em profundidade ao longo do declive, com influência direta na retenção de umidade dos solos ou mesmo na formação de ambientes paludículos, determinaram grupos distintos de espécies e fisionomias florestais: (i) um grupo de espécies de ocorrência típica nas fisionomias de Cerrado e fortemente associado às cotas mais elevadas (solos menos férteis, bem drenados e porcentagens mais baixas de argila e silte nas camadas mais profundas), entre as quais: Matayba juglandifolia, Trichilia pallida, Lithraea molleoides, Anadenanthera falcata, Myrcia tomentosa, Copaifera langsdorffii, Erytrhoxylum pelleteranum, Platipodium elegans, Chrysophyllum marginatum, Luehea divaricata, entre outras e (ii) um grupo com espécies indicadoras de Florestas Paludículas ou de ocorrência comum nestas fisionomias, associado aos solos das cotas mais baixas (Gleissolos), com porcentagens altas de argila e silte nas camadas superficiais, mais férteis e maior retenção hídrica: Cecropia pachystachya, Citronella gongonha, Rapanea guianensis, Talauma ovata e Tapirira guianensis. Pode-se considerar um terceiro grupo de transição entre Floresta Estacional Semidecídua e Cerradão, nas cotas intermediárias e menos úmidas (espécies amostradas em parcelas localizadas nas bordas das Florestas Paludículas), onde ocorreram espécies tanto de ambiente de Cerradão, como de Floresta Estacional Semidecídua, e algumas poucas de ambiente paludículo. As porcentagens mais elevadas de Areia nos solos do Sítio Pratinha, com influência na menor retenção hídrica e também nos índices de fertilidade (solos álicos, com maior acidez e os menos férteis), podem explicar algumas diferenças na composição e abundância das espécies entre fisionomias florestais iguais. O Cerradão da Fazenda Monte Belo, mostrou-se diferente floristicamente do Cerradão do Sítio Pratinha. Esta mesma diferença ocorreu em relação às Florestas Paludículas da Fazenda Magnólia e a do Sítio Pratinha. As poucasespécies de ocorrência comum tiveram populações diferentes. A CCA evidenciou também correlações de algumas espécies com determinadas variáveis de solo. / In order to understand what abiotic factors determine the occurrence of different forest formations in the region of Batatais, coordinated between 20038\'S and 20058\'S and 47037\'W and 47028\'W, three agricultural properties were chosen (Monte Belo, in the city of Restinga, SP and Magnolia and Pratinha in Batatais, SP, Brazil), which had forests representative of the region (swamp forest, semi-deciduous riverine forest and forested savanna). To describe the floristic composition and structure of the arboreal community, 05 plots of 10 x 10 meters around each tensiometric station were sampled. For the study of abiotic factors, the physico-chemical characteristics of the soils, the soil-water-retention curves and the groundwater fluctuation were determined. The discrimination of the environmental variables and arboreal species were made through the Principal Components Analysis (PCA), and in the correlation between the abundance of species and abiotic factors, direct analyses of gradient through Canonical Correspondence Analysis (CCA) were made. The texture of the soil (levels of clay, silt and sand) and the position on the ground (altitude) were the most important environmental variables in the distribution of species and variations of forest physiognomies, with influence in the retention rates of water and soil fertility. These differences in levels of clay in depth along the slope, with direct influence on the retention of soil moisture and even in the development of swampy environment, determined distinct groups of species and forest physiognomies: (i) a group of species of typical occurrence in physiognomies of Forested Savanna and strongly associated with higher altitude (less fertile, well-drained soil and lower percentages of clay and silt in the deeper layers), including: Matayba juglandifolia, Trichilia pallida, Lithraea molleoides, Anadenanthera falcata, Myrcia tomentosa, Copaifera langsdorffii, Erytrhoxylum pelleteranum, Platipodium elegans, Chrysophyllum marginatum, Luehea divaricata, among others, and (ii) a group with indicator species of Swamp Forests or common occurrence in these physiognomies, associated with lower altitude (Gleisoil), with high percentages of clay and silt in the upper and more fertile layers, and greater water retention: Cecropia pachystachya, Citronella gongonha, Rapanea guianensis, Talauma ovata and Tapirira guianensis. A third group of transition between Semi-deciduous Forest and Forested Savanna, in intermediate altitude and soils less humid (species sampled in plots located at the edges of Swamp Forests), occurred both in the Forested Savanna and in Semi-deciduous Forest and a few in swampy environment. The highest percentages of sand in the soil of Pratinha, with less influence on water retention and also on the rates of fertility (alic soils, with greater acidity and less fertile), may explain some differences in the composition and abundance of species of forest physiognomies equal. The forested Savanna of Monte Belo, has proved floristically different from the Forested Savanna of Pratinha. This same difference occurred in swamp forests of Magnolia and Pratinha. The few species of common occurrence had differentpopulations. The CCA also revealed correlations of some species with certain variables of soil.
