1. Vibration analysis of laminated functionally graded shallow shells with clamped cutout of the complex form by the Ritz method and the R-functions theory
Abstract The R-functions theory and Ritz approach are applied for analysis of free vibrations of laminated functionally graded shallow shells with different types of curvatures and complex planforms. Shallow shells are considered as sandwich shells of different types: a) face sheets of the shallow shells are made of a functionally graded material (FGM) and t

2. Imputation of genetic composition for missing pedigree data in Serrasalmidae using morphometric data
ABSTRACT This study aimed to impute the genetic makeup of individual fishes of Serrasalmidae family on the basis of body weight and morphometric measurements. Eighty-three juveniles, belonging to the genetic groups Pacu, Pirapitinga, Tambaqui, Tambacu, Tambatinga, Patinga, Paqui and Piraqui, were separated into 16 water tanks in a recirculation system, with

3. Mathematical Modeling of the Ester Oil-Refrigerant R134a Mixture Two-Phase Flow with Foam Formation Through a Small Diameter Tube
This work presents a mathematical modeling to study the ester oil ISO VG-10-refrigerant R134a mixture two-phase flow with foam formation through a 3.22 mm ID tube. Based on experimental visualization results, the flow is divided into three regions: a single phase flow at the inlet of the tube; an intermediary bubbly flow region; and a foam flow region at the

4. Distribuições em série de potências modificadas inflacionadas e distribuição Weibull binominal negativa / Inflated modified power serie distribution and Weibull negative binomial
In this paper, some result such as moments generating function, recurrence relations for moments and some theorems of the class of modified power series distributions (MPSD) proposed by Gupta (1974) and of the class of inflated modified power series distributions (IMPSD) both at a different point of zero as the zero point are presented. The standard Poisson

5. Behavior of granite-epoxy composite beams subjected to mechanical vibrations
The capacity to damp mechanical vibrations is one of the most important properties of granite-epoxy composites, even superior to the cast iron one. For this reason, these materials have been adopted for manufacturing of tool machine foundations and precision instruments. This work presents a study concerning the behavior of particulate composite beams, based

6. Modelo de mistura padrão com tempos de vida exponenciais ponderados
In this work, we brie_y introduce the concepts of long-term survival analysis. We dedicated ourselves exclusively to the standard mixture cure model from Boag (1949) and Berkson &Gage (1952), showing its deduction and presenting the imunes probability function, which is taken from the model itself and we investigated the identi_ability issues of the mixture

7. CARACTERIZAÇÃO TECNOLÓGICA DE UM SINTER FEED HEMATÍTICO CONTENDO DIFERENTES PROPORÇÕES E TIPOS DE SÍLICA NAS FRAÇÕES ADERENTES, INTERMEDIÁRIAS E NUCLEANTES
There are important Vale iron ore reserves located in the state of Minas Gerais. The hematite/itabirite relationship in the ROMs has been decreasing compared to the last decade. The beneficiation plants have been concentrating its efforts on reducing the silica content in the sinter feed in order to reach the quality levels demanded for the sintering process

8. Characteristics of flow in wet conical spouted beds of unequal-sized spherical Particles
Interparticle forces, developed in wet spouted beds composed of a mixture of spherical particles with different size distributions, intensify particle segregation mechanisms interfering in gas distribution inside the bed and, consequently, in the spouting flow characteristics. Therefore, this paper is aimed at describing the effect of interparticle forces on

9. Utilização de técnicas bayesianas em modelos de regressão de Poisson para dados de contagem longitudinais e dados de contagem com medidas repetidas apresentando excesso de zeros
In medical and biological researches we often .nd count data. For longitudinal count data, usual Poisson regression models, assuming independence among observations, are not applicable because of the correlation of these measures. This work presents hierarchical Bayesian models considering random eects to analyze longitudinal count data. A Normal and a Gamma

10. SeleÃÃo de protÃtipos: combinando auto-geraÃÃo de protÃtipos e mistura de gaussianas
Prototype selection is a machine learning scheme in which the main purpose is to choose pattern vectors from the training dataset that achieve a better fit to data point distributions and maintain class separation. The aim of this kind of technique is to find the smallest possible prototype set that minimizes the classification error rate. Prototype-based st

11. Sensoriamento remoto aplicado na analise da cobertura vegetal das reservas de desenvolvimento sustentavel Amana e Mamiraua / Remote sensing applied in vegetation analysis of Amana and Mamiraua sustainable-use protected areas
The knowledge of the Amazon biodiversity, especially that related to its vegetation cover, has been the subject of several studies involving the investigation of its ecological-evolutional processes and its dynamics as an integrated and complex set of biological units. The development of Remote Sensing technologies and methodologies is becoming increasingly

12. Cerrado sensu stricto sobre Neossolo Quartzarênico : fitogeografia e conservação
The Cerrado biome presents a large spatial heterogeneity and is characterized as having elevated beta diversity. The Sete Cidades National Park (PNSC) and Chapada Grande Meridional, both located at the state of Piauí, show great landscape diversity with different physiognomies and soils types. In this study, we investigated the woody vegetation of the cerra
