1. An Experimental Analysis of Three Pseudo-peripheral Vertex Finders in conjunction with the Reverse Cuthill-McKee Method for Bandwidth Reduction
RESUMO. A necessidade de se determinar vértices pseudoperiféricos surge de diversas abordagens por teoria dos grafos de ordenação de linhas e colunas de sistemas de equações lineares compostos de matrizes esparsas. Neste trabalho, são mostrados resultados de dois algoritmos para encontrar vértices pseudoperiféricos: George-Liu e Kaveh-Bondarabady. O

2. Reinforced Glass-ceramics: Parametric Inspection of Three-Dimensional Wear and Volumetric Loss after Chewing Simulation
Resumo O objetivo deste estudo foi investigar o desgaste tridimensional, perda volumétrica e rugosidade após a simulação de mastigação de dois materiais vitro-cerâmicos. Discos de dissilicato de lítio (LD, Emax CAD, Ivoclar) e silicato de lítio reforçado com zircônia (ZLS, Vita Suprinity, Vita Zhanfabrick) (n=20/g) foram confeccionados e digitaliz

3. Evaluation of caries-associated virulence of biofilms from Candida albicans isolated from saliva of pediatric patients with sickle-cell anemia
A previous study demonstrated that the amount of Candida spp. in saliva is higher in children with sickle-cell disease. The results from a recent study demonstrate its participation in the etiology of dental caries. Objective This study assessed caries-associated virulence (production of acid, extracellular polysaccharides, proteins and metabolic activity

4. Wavelength assignment using a hybrid evolutionary computation to reduce cross-phase modulation
In this paper, we propose a hybrid methodology based on Graph-Coloring and Genetic Algorithm (GA) to solve the Wavelength Assignment (WA) problem in optical networks, impaired by physical layer effects. Our proposal was developed for a static scenario where the physical topology and traffic matrix are known a priori. First, we used fixed shortest-path routin

5. Normal lymphocyte immunophenotype in an elderly population
OBJECTIVE: The aim of this work was to evaluate the lymphocyte immunophenotype in an elderly population.METHODS: This study enrolled 35 over 60-year-old volunteers and a control group composed of 35 young adults. The study included elderly without diseases that might affect the functioning of the immune system. These individuals were consulted by doctors and

6. Bond Graph modeling of the human esophagus and analysis considering the interference in the fullness of an individual by reducing mechanical esophageal flow
INTRODUCTION: This paper shows a proposal for the mathematical modeling of the human esophagus using Bond Graph formalism and the interference in the satiation of an individual by way of an Esophageal Flow Controller (EFC). Therefore, it was evaluated that there is a significant change in fall time that affects the process of human satiety when the diameter

7. Automatic hippocampus segmentation through similarity cloud / Segmentação da estrutura cerebral hipocampo por meio de nuvem de similaridade
The hippocampus is a particular structure that plays a main role in human memory systems. Tissue modifications of the hippocampus lead to neurodegenerative diseases as epilepsy, multiple sclerosis, and dementia, among others. To measure hippocampus atrophy, it is crucial to get its isolated representation from the whole brain volume. Separating the hippocamp

8. Aplicabilidade de parâmetros antropométricos e de bioimpedância elétrica na avaliação do estado nutricional de idosos / Applicability of anthropometric parameters and bioelectrical impedance in the nutritional status assessment of elderly
This study aimed to evaluate the applicability of phase angle (PA) and bioelectrical impedance vector analysis (BIVA) in the nutritional status assessment of elderly. There was an epidemiological study of cross design, in which 70 elderly individuals aged 60 to 98 years old (n=33 men; n=37 women) assisted by Family Health Program of the municipality Viçosa-

9. Nowhere-zero flows and colorings of graphs / Fluxos inteiros e colorações
The theme of this thesis is nowhere-zero flows and colourings of graphs, two subjects that are closely related. We focus mainly on the three Conjectures of Tutte concerning 5-, 4- and 3-nowhere-zero flows. These conjectures were proposed, respectively, in the 50 s, 60 s and 70 s; all of them remain open so far. In this thesis we present three different appro

10. Uso dos mÃtodos AMMI e GGE biplot para anÃlises de adaptabilidade e estabilidade de hÃbridos de milho e estratificaÃÃo ambiental / The use of AMMI and GGE biplot methods for analysis of adaptability and stability of maize hybrids and environmental stratification
This work was carried out for evaluating stability, adaptability and environmental stratification, through the AMMI and GGE biplot methods by using maize hybrids trials data evaluation and for comparing the efficiency of these methods. Grain yield data originating from final trials of maize hybrids evaluation supplied by the Monsanto company were used and th

11. Sequential and parallel approaches to reduce the data cube size.
Since the introduction of Data Warehouse (DW) and Online Analytical Processing (OLAP) technologies, efficient computation of data cubes has become one of the most relevant and pervasive problems in the DW area. The data cube operator has exponential complexity; therefore, the materialization of a data cube involves both huge amount of memory and substantial

12. Geração de expressões algébricas para processos de negócio usando reduções de digrafos série-paralelo / Generation of algebraic expressions for business processes using reductions on series-parallel digraphs
Modeling and execution control are complementary approaches of business process management that have been developed independently. On one hand, modeling is usually performed by business specialists and explores semantical aspects of the business process. On other hand, execution control studies consistent and efficient mechanisms for implementation. This wor
