Abstract:

A caracterização de redes e o estudo de sistemas, ambos utilizando grafos, é algo muito usado por várias áreas científicas. Uma das linhas deste estudo é denominada de grafos aleatórios, que por sua vez auxilia na criação de modelos para análise de redes reais. Consideramos um modelo de grafo aleatório não homogêneo criado por Kang, Pachón e Rodríguez (2016), cuja construção é feita a partir da realização do grafo binomial G(n; p). Para este modelo, estudamos argumentos e métodos usados para encontrar resultados sobre o limiar de conectividade, importante propriedade relacionada a existência a

Abstract:

Estudamos sistemas de passeios aleatórios sobre os vértices de um grafo completo. Inicialmente há uma partícula em cada vértice do grafo das quais somente uma está ativa, as outras estão inativas. A partícula ativa realiza um passeio aleatório simples a tempo discreto com tempo de vida que depende do passado do processo, movendo-se ao longo de elos. Quando uma partícula ativa encontra uma inativa, esta se ativa; quando salta sobre um vértice já visitado, morre. O objetivo desta dissertação é estudar a cobertura do grafo completo, ou seja, a proporção de vértices visitados ao fim do processo,

Abstract:

Modern lifestyles in an increasing number of human societies include consuming an excess of saturated fats and refined sugars as well as enjoying microbiologically aseptic environments. Maintaining the appropriate distribution of gut microbial populations (eubiosis) is emerging as an attractive approach to prevent ectopic fat accumulation and insulin resistance (IR), and to avert the progression of diabetes. Functional food components are those that help maintain the normal bodily functions beyond providing energy or building blocks. They may bring about physiological health benefits for

Abstract:

The capability of manipulating objects is fundamental for robots in order to interact and integrate in the environment they are deployed in. Since most manipulation actions involve or begin with picking up objects, grasping is an integral part of any manipulation toolbox. Although planning grasps on known object shapes is a mature research field with decades of work behind it, such information is not available in many realistic scenarios. For robots deployed in dynamic and unstructured environments such as homes, stores or even outdoor settings can be cumbersome or outright unfeasible to know

Abstract:

The abelian sandpile model, or chip firing game, is a cellular automaton on finite directed graphs often used to describe the phenomenon of self organized criticality. Here we present a thorough introduction to the theory of sandpiles. Additionally, we define a symmetric sandpile configuration, and show that such configurations form a subgroup of the sandpile group. Given a graph, we explore the existence of a quotient graph whose sandpile group is isomorphic to the symmetric subgroup of the original graph. These explorations are motivated by possible applications to counting the domino tiling

Abstract:

A model for DNA recombination uses 4-valent rigid vertex graphs, called assembly graphs. An assembly graph, similarly to the projection of knots, can be associated with an unsigned Gauss code, or double occurrence word. We define biologically motivated reductions that act on double occurrence words and, in turn, on their associated assembly graphs. For every double occurrence word w there is a sequence of reduction operations that may be applied to w so that what remains is the empty word, [epsilon]. Then the nesting index of a word w, denoted by NI(w), is defined to to be the least number of

Abstract:

Em 2007 o Painel Intergovernamental Sobre Mudanças Climáticas relataram mudanças climáticas nas últimas décadas, principalmente aumento de temperatura. Tal fato tem preocupado cientistas sobre o futuro. Assim, estudos tem sido realizados para avaliar possíveis impactos na agropecuária. As pastagens no Brasil podem ser particularmente afetadas, devido a grande extensão de terras ocupadas, muitas delas em áreas marginais. No estado de São Paulo, estas mudanças poderão ser importantes para a Braquiaria brizantha cv. Marandu, gênero presente em cerca de 7,19 milhões de hectares. Assim, objetivou-s

Abstract:

We used a divide-and-conquer algorithm to recursively solve the two-dimensional problem of protein folding of an HP sequence with the maximum number of H-H contacts. We derived both lower and upper bounds for the algorithmic complexity by using the newly introduced concept of multi-directional width-bounded geometric separator. We proved that for a grid graph G with n grid points P, there exists a balanced separator A subseteq P$ such that A has less than or equal to 1.02074 sqrt{n} points, and G-A has two disconnected subgraphs with less than or equal to {2over 3}n nodes on each subg

Abstract:

The work conducted in this thesis examines the nature of circumstellar discs by investigating irradiance and polarization of scattered light. Two circumstellar discs are investigated. Firstly, H-band high contrast imaging data on the transitional disc of the Herbig Ae/Be star HD169142 are presented. The images were obtained through the polarimetric differential imaging (PDI) technique on the Very Large Telescope (VLT) using the adaptive optics system NACO. Our observations use longer exposure times, allowing us to examine the edges of the disc. Analysis of the observations shows distinct signs

Abstract:

A partir da solução analítica obtida para o campo turbulento gerado por duas grades oscilantes em fluido em repouso, considerados os casos de viscosidade constante e viscosidade variável, foram estudados escoamentos turbulentos complexos. A partir de proposta de equação governante linear ainda não publicada de SCHULZ (2003a), foram obtidas soluções promissoras e exploradas possibilidades de generalização. As equações em questão baseiam-se no modelo &#954-&#949. A ferramenta de trabalho no estudo das soluções teóricas foi o programa Mathematica. Embora essa ferramenta simplifique o trabalho mec

Abstract:

Este trabalho visa a estudar o modelo de percolação independente, de Bernoulli, em grafos, tendo como objetivo principal obter condições que garantam a ocorrência de transição de fase. Iniciamos apresentando as definições e algumas técnicas fundamentais para o modelo de percolação (de elos ou de sítios) em um grafo infinito, conectado e localmente finito. Demonstramos então dois resultados essenciais: os fatos do parâmetro crítico não depender da escolha do vértice e da existência de um aglomerado infinito ter probabilidade 0 ou 1. Também obtemos um limitante inferior para o parâmetro crítico

Abstract:

This thesis examines the in-vitro and in-vz’vo effect of rifampicin (a known antistaphylococcal agent) following prosthetic graft impregnation, to prevent and treat Staphylococcus epidermidis (MRSE) and Staphylococcus aureus (MRSA) prosthetic vascular graft infections. In addition the effects of rifampicin on intirnal hyperplasia were analysed. Using a disc difiusion technique, one square centimetre segments of Gelsofi, Gore-Tex, Fluoropassiv or Thoratec were impregnated with rifampicin at concentrations of 1.2mg/ml, 10 mg/ml or 30 mg/ml and placed on a bacterial lawn of MRSA or MRSE.

Abstract:

This study aimed at contributing to the understanding the physiology, structural distribution and management of Napier grass (<i>Pennisetum purpureum</i> Schum.) since its versatility promoted its wide distribution in tropical and subtropical areas of the world. A series of three experiments were developed to determine growth dynamics, sward structure, and forage quality at different physiology ages. In the first study in long established pasture of Napier grass were applied three fertilizer levels of dairy cattle manure and three cutting intervals. A second experiment included two inorganic
