1. Numerical implementation of a micromechanics-based viscoelastic model for geomaterials with isotropically distributed micro-fractures
Abstract The constitutive behavior of geomaterials is generally affected by the presence at different scales of discontinuity surfaces with different sizes and orientations. According to their mechanical behavior, such discontinuities can be distinguished as cracks or fractures. Fractures are interfaces that can transfer normal and tangential stresses, where

3. A Model for Homogenization of Linear Viscoelastic Periodic Composite Materials with Imperfect Interface
Abstract In this paper, a micromechanical extension of the finite-volume direct averaging micromechanics theory (FVDAM) is presented for evaluation of the homogenized relaxation moduli of linear viscoelastic unidirectional fiber reinforced composites with periodic microstructures. Such materials are assumed as composed of repeating unit cell with arbitrary i

4. Desenvolvimento de um programa computacional para avaliação postural de código aberto e gratuito / Not informed by the author
The use of computational tools for postural evaluation has been very valuable in the detection of postural changes, however the use of these programs requires complex hardware structures and involves high costs for researchers in physiotherapy, physical education and the scientific community. In 2005, the Postural Assessment Software (SAPO) became to be a fr

5. Numerical combination for nonlinear analysis of structures coupled to layered soils
This paper presents an alternative coupling strategy between the Boundary Element Method (BEM) and the Finite Element Method (FEM) in order to create a computational code for the analysis of geometrical nonlinear 2D frames coupled to layered soils. The soil is modeled via BEM, considering multiple inclusions and internal load lines, through an alternative fo

6. Modelagem computacional de escoamentos de fluidos em solos não saturados / Computational modeling of fluid flow in unsaturated soils.
O movimento da água em solos não saturados (zona vadosa) pode ser descrito pela equação de Richards, obtida pela combinação da equação de conservação de massa e da lei de Darcy-Buckingham. Usualmente essa equação é representada sob três formas básicas: h - baseada na carga de pressão, θ - baseada na umidade volumétrica e mista - baseada

7. Qualidade de artigos na wikipedia para seus usuários - análise e proposta de interação
Wikipedia has drawn much attention from scientists because of its bold proposal to create an open, collaborative encyclopedia, and even more for being so popular. Since the creation of Wikipedia in 2001 by Jimbo Wales and Larry Sanger, its growth hás been dizzying surpassing 2.5 million articles in English version. However, the use of such content faces the

8. An efficient C0 FE model for the analysis of composites and sandwich laminates with general layup
A C0 continuous finite element model is developed to model the refined higher order shear deformation theory. The proposed element is an upgraded version of an element based on higher order shear deformation theory. The C0 continuity of the present element is compensated in the stiffness matrix calculations. The computational efficiency is achieved by the C0

9. High-order finite volume method for solving viscoelastic fluid flows
Computational Fluid Dynamics (CFD) is widely used by polymer processing industries in order to evaluate polymeric fluid flows. A successful computational code must provide reliable predictions (modeling) in a fast and efficient way (simulation). In this work, a new approach to solve the governing equations of viscoelastic fluid flows is proposed. It is based

10. Analysis of binding properties and specificity through identification of the interface forming residues (IFR) for serine proteases in silico docked to different inhibitors.
Background: Enzymes belonging to the same super family of proteins in general operate on variety of substrates and are inhibited by wide selection of inhibitors. In this work our main objective was to expand the scope of studies that consider only the catalytic and binding pocket amino acids while analyzing enzyme specificity and instead, include a wider cat

11. PARALLEL TOPOLOGICAL SUPPORT FOR FINITE ELEMENT MESHES IN DYNAMIC FRACTURE AND FRAGMENTATION ANALYSES / SUPORTE TOPOLÓGICO EM PARALELO PARA MALHAS DE ELEMENTOS FINITOS EM ANÁLISES DINÂMICAS DE FRATURA E FRAGMENTAÇÃO
Fracture propagation and fragmentation phenomena in solids can be described by Cohesive Zone Models and simulated with the Finite Element Method. Among the computational approaches of recent interest for fracture representation in finite element meshes are those based on cohesive elements. In those approaches, fracture behavior is represented by cohesive ele

12. A new architectural approach for interoperability of real-time system components.
Interoperability is a key property of distributed applications, which is hard to achieve due to the large number of interoperating components and semantic heterogeneity. Distributed Real-Time Systems (RTS) have strict requirements of performance. The interoperability of Distributed RTS components challenges the computer engineering community to fulfill these
