Composite resin is the dental material that predominates within restorative dentistry, as it is a treatment with lower cost, providing excellent aesthetics and functionality. The application of direct composite resin veneers is a technique used to perform aesthetic changes in teeth, such as changing color, shape, filling spaces between teeth (diastema), correction of fractures, among others. The general objective of the present study carried out in the form of a narrative review of the literature is to demonstrate the importance of the direct veneer technique in smile esthetics. The direct veneer technique in composite resin is an excellent treatment option, bringing a natural and harmonious final result. It is a minimally invasive technique, therefore more conservative. Therefore, it can be said that there are several procedures indicated to bring back the function and aesthetics of patients, but veneers are one of the most used procedures for a perfect smile.

Presents an overview of the use of facets in the organization of information, between physical and digital environments. Is based on the context of the organization of knowledge, which is regarded as the most important framework in the theory of information organization, and is emphasized in Ranganathan's theory of faceted classification (1892-1972). Addresses three basic points of discussion about ranganathan theory: the five fundamental categories, personality-matter-energy-space-time; systematic multidimensionality; and the canons of ranks and class chains. Is characterized as an exploratory research, to identify environments that use facets, and bibliographical. The results are that most of the factional models are applied in digital environments, which are purely academic-professional models, that the documentary (physical) systems were the most adopted application supports, that models were identified in the period from 1933 to 2017 and that the fundamental category [Personality] was the most cited. Was concluded that the presence of facets in systems of knowledge organization promulgate that the same product have different interpretations in the same taxonomy, formalizes the multidimensionality idealized in Ranganathan's theory of the faceted classification, but without being followed in full in some cases, adopts custom mnemonics and shows that the environments where they are adopted vary from physical to digital, from physical libraries to digital repositories.

This máster thesis presents research on the correlation of lexical information in texts in Portuguese with personality characteristics and model Big Five facets of IPIP-NEO. It elaborates, especially, on the use of classes of affective feelings LIWC lexicon. The main goal of this work is to relate the factors of the Big Five model and the IPIP-NEO facets of IPIP-NEO 120 and TIPI questionnaires with the posts of Facebook social network. For this, a tool called Personalitatem Lexicon was built. The methodology used to achieve the research objectives was bibliographical which were researched and analyzed the work done on personality inferences from texts. The result of the experiment shows that the inference of personality from the questionnaires have more precise conclusions for the same contain specific questions and answers to measure such characteristic. Already personality inference for posts is more susceptible to noise because not all experienced situations are exposed on the social network. However, inference of personality posts is possible, but the results are the moments A presente dissertação apresenta pesquisa sobre a correlação de informações léxicas em textos em Português com características de personalidade do modelo Big Five e as facetas do IPIP-NEO. Discorre-se, especialmente, sobre o uso das classes de sentimentos afetivos do léxico LIWC. O objetivo principal desse trabalho é correlacionar os fatores do Big Five e as facetas do IPIP-NEO dos questionários IPIP-NEO 120 e TIPI com os posts da rede social Facebook. Para isso, foi construída uma ferramenta chamada de Personalitat em Lexicon. A metodologia adotada para atingir os objetivos da pesquisa foi de caráter bibliográfico onde foram pesquisados e analisados os trabalhos desenvolvidos sobre inferência de personalidade a partir de textos. O resultado do experimento mostra que a inferência de personalidade a partir dos questionários tem conclusões mais precisas pelo mesmo conter perguntas e respostas específicas para aferir tal característica. Já a inferência de personalidade por posts é mais susceptível a ruídos porque nem todas as situações vividas são expostas na rede social. Contudo, inferir personalidade por posts é possível, mas os resultados são retratos de momento.

A stable set of a graph is a set of pairwise non-adjacent vertices. The maximum stable set problem is to find a stable set of maximum cardinality in a given graph. The maximum induced k-partite subgraph problem is to find k stable sets such that their union has maximum cardinality. Besides having applications in various fields, including computer vision, molecular biology and VLSI circuit design, these problems also model other important combinatorial problems, such as set packing and vertex coloring. In the present work, we study the facial structure of the polytopes associated with both problems. First, we describe a new facet generating procedure for the stable set polytope, which unifies and subsumes several previous procedures. Besides generating many well-known facet inducing inequalities, this procedure can also generate new facet-inducing inequalities which have not been previously described. Then, we study the maximum induced k-partite polytope formulated by asymmetric representatives. We describe its simplest facets, show that some of its facets arise from vertex induced subgraphs, and identify two classes of subgraphs which generate facets of the polytope. To reach these main results, we study the affine equivalence between polyhedra, and also develop a new facet generating procedure for general polyhedra which subsumes the many versions of the lifting of variables. Um conjunto independente de um grafo é um subconjunto de vértices que não contém nenhum par de vértices vizinhos. O problema do maior conjunto independente consiste em encontrar um conjunto independente de cardinalidade máxima. O problema do maior subgrafo induzido k-partido consiste em encontrar k conjuntos independentes cuja união tenha cardinalidade máxima. Além de possuírem aplicação em diversas áreas, como visão computacional, biologia molecular e projeto de circuitos integrados, estes problemas também modelam outros problemas de otimização combinatória, como empacotamento de conjuntos e coloração de vértices. Neste trabalho, estudamos os politopos associados aos dois problemas. Primeiro, descrevemos um novo procedimento de geração de facetas para o politopo de conjuntos independentes, que unifica e generaliza diversos procedimentos anteriores. Além de gerar várias classes de desigualdades indutoras de facetas já conhecidas, este procedimento também gera novas desigualdades que ainda não foram descritas na literatura. Em seguida, estudamos o politopo do subgrafo induzido k-partido associado à formulação por representantes de cor. Identificamos suas facetas mais simples, mostramos que facetas podem ser geradas a partir de subgrafos induzidos, e descrevemos duas classes de subgrafos que geram facetas deste politopo. Para obter os principais resultados desta dissertação, fazemos um estudo da relação de afim-isomorfismo entre poliedros, e desenvolvemos um novo procedimento de conversão de faces em facetas que generaliza as diversas versões do procedimento de levantamento de variáveis.

Software Reuse has been considered a key concept to increase the quality and productivity of the software development by the reuse of existing artifacts, avoiding build new ones from scratch. However, In order to obtain effective benefits from the software reuse is necessary a set of complementary resources such as: education, active management support and the introduction of appropriate process and tools. In fact, resources that provide mechanism to ease the access of reusable components, such as search and retrieval tools, appear as potential instruments in favor of reuse programs adoption in the organizations. One of the challenges of the search and retrieval tools is how to make that existing components returned have a significant relevance. In this sense, the use of the faceted approach rises as a suitable alternative. This approach proposes the creation of a vocabulary supported by attributes, dividing the components into group of classes based on pre-defined keywords, increasing the level of precision and providing a more flexible classification. Thus, this work presents an extension of search and retrieval tool of reusable components, source code in particular, using the faceted classification approach. In addition, also was developed an auxiliary tool to aid the Domain expert to perform his activities using this approach. Finally, an experimental study evaluates the proposed solution
