1. Kelvin Viscoelasticity and Lagrange Multipliers Applied to the Simulation of Nonlinear Structural Vibration Control
Abstract This study proposes a new pure numerical way to model mass / spring / damper devices to control the vibration of truss structures developing large displacements. It avoids the solution of local differential equations present in traditional convolution approaches to solve viscoelasticity. The structure is modeled by the geometrically exact Finite Ele

2. Explorando a resoluÃÃo de problemas de estruturaaditiva usando diferentes tipos de representaÃÃes :reta numÃrica e material manipulativo
This study assessed the use of different types of representational resources (numerical straight line and manipulative material) in the solving of problems of additive structure in 39 children with an average age of 9 years and 4 months in primary education. The study consisted of a pretest, direct intervention, immediate posttest and later posttest. The chi

3. An investigation of singularities in robot kinematic chains aiming at building robot calibration models for off-line programming
Robot Calibration is a term applied to the procedures used in determining actual values that describe the geometric dimensions and mechanical characteristics of a robot or multibody structure. A robot calibration system must consist of appropriate robot modeling techniques, accurate measurement equipment, and reliable model parameter determination methods. F
