1. A Timoshenko Piezoelectric Beam Finite Element with Consistent Performance Irrespective of Geometric and Material Configurations
Abstract The conventional Timoshenko piezoelectric beam finite elements based on First-order Shear Deformation Theory (FSDT) do not maintain the accuracy and convergence consistently over the applicable range of material and geometric properties. In these elements, the inaccuracy arises due to the induced potential effects in the transverse direction and ine

2. Modified couple stress-based third-order theory for nonlinear analysis of functionally graded beams
A microstructure-dependent nonlinear third-order beam theory which accounts for through-thickness power-law variation of a two-constituent material is developed using Hamilton's principle. The formulation is based on a modified couple stress theory, power-law variation of the material, and the von Kármán nonlinear strains. The modified couple stress theory

3. A maximum margin-based kernel width estimator and its application to the response to neoadjuvant chemotherapy
INTRODUCTION: Function induction problems are frequently represented by affinity measures between the elements of the inductive sample set, and kernel matrices are a well-known example of affinity measures. METHODS: The objective of the present work is to obtain information about the relations between data from a calculated kernel matrix by initially assumin

4. A responsabilidade social empresarial como meio propulsor da efetivaçăo de direitos trabalhistas
One of the main features of postmodernity is the worldwide expansion of capitalism effects, both positive and negatives effects. Money appears to be volatile; the goods become global, being produced and consumed in different continents; different cultures mingle, collide and sometimes originate new cultural expressions; inequalities and tensions grow in geom

5. Ensinando Matemática para alunos diagnosticados como portadores de Transtorno de Déficit de Atenção/Hiperatividade (TDAH): uma proposta baseada no desenvolvimento da autorregulação
The lack of attention, hyperactivity and/or impulsivity are characteristics increasingly seen in children nowadays. When those characteristics persist for a long period of time and are intense, it can be an evidence of Attention deficit /hyperactivity disorder (ADHD). ADHD affects individuals‟ lives damaging many areas, as adapting and developing in th

6. Measuring statistical geometric properties of tomographic images of soils
Porous media modeling is relevant in several applications, such as agricultural engineering, where soil compaction analysis requires the estimation of soil transport properties. For example, the prediction of root growing patterns and their environmental impact is usually measured by analyzing soil fluid infiltration capacity and water retention. Recently, t

7. 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

8. A organização da prática educativa em geometria: Contribuições da teoria piagetiana
This research sought to establish inter-relations between the results of the studies of the Piaget and Inhelder to the perception and representation of space and the process of teaching of geometry; identify as children establish the spatial relationships of topological nature, and projective Euclidian and highlight the contributions of those studies. Theref

9. A indisciplina que muda a arquitetura : a dinâmica do espaço doméstico no Distrito Federal
In architecture, building the space for housing implies the construction of place, as the space to be inhabited and lived. This thesis is an attempt to contribute to a broad spectrum of studies related to domestic space in a specific perspective, since the analyses are based on the morphology of the apartments (geometric and configurational features) and its

10. Uma formalização da teoria de reescrita em linguagem de ordem superior
Theories for Abstract Reduction Systems (ARS) and Term Rewriting Systems (TRS) in the proof assistant PVS (Prototype Verification System) called ars and trs, respectively, we developed. The ars theory built on the PVS library for binary relations, contains specifications of notions such as reduction, confluence, normal forms, and non basic concepts such as N

11. Análise multi-temporal de cenas do satélite quickbird usando um novo paradigma de classificação de imagens e inferências espaciais. Estudo de caso: Belo Horizonte, MG / Multi-temporal analysis of quickbird images using a new classification paradigm and spatial inferences. A case study: Belo Horizonte - MG, Brazil
Due to the strong urbanization process occurring in Brazil and of population increase in cities, and consequently to serious impacts on environment, there is a growing need to develop methodologies and technologies which allow to monitor, analyze and to make an intervention at the urban expansion. Belo Horizonte (State Capital of Minas Gerais) is a highly co

12. Morfometria geometrica e modelagem matematica em Lantana camara L. (Verbenaceae) / Mathematical modeling and mporphometric relations in the vegetative body of Lantana camara L. (Verbenaceae) in Brazil
The taxonomy of Lantana camara has been the target of discussion by taxonomists all over the world. The morphological, ecological and chemical plasticity observed is very extensive. Some autors consider that L. camara is a species complex instead of a monotypic taxon, composed of up to 150 different taxa. In this sudy, the variability of L. camara is studied
