1. Numerical fundamentals and interactive computer graphics system for the nonlinear analysis of planar frames
Abstract Recent scientific and computational advances have facilitated the analysis of slender structural systems subject to instability. With the employment of more sophisticated numerical tools and algorithms, it is possible to accurately determine the critical points (limit and bifurcation loads) as well as the post-critical behavior of the structural sys

2. ANALYSIS OF ELASTICITY IN WOODS SUBMITTED TO THE STATIC BENDING TEST USING THE PARTICLE IMAGE VELOCIMETRY (PIV) TECHNIQUE
ABSTRACT The most important parameter in terms of material mechanical behavior knowledge is the modulus of elasticity, being traditionally obtained through destructive tests. The objective of this study is the verification of the potential use of the particle image velocimetry technique (PIV) as a tool to obtain the modulus of elasticity in sawed wood sample

3. Maps of deformations in a cantilever beam using particle image velocimetry (PIV) and speckle patterns
PIV (particle image velocimetry) has been spreading in studies that use the movement of particles to monitor the displacement of an object or the flow of a fluid by means of velocity vectors using optical techniques and second order statistics. PIV is also known as laser speckle velocimetry when associated with speckle patterns. This technique has been used

4. OBJECT FRACTURE ANIMATION BASED ON VERTEX CLUSTERS / ANIMAÇÂO DE FRATURA DE OBJETOS BASEADA EM AGRUPAMENTOS DE VÉRTICES
Neste trabalho, estendemos o método de simulaão de objetos deformáveis de Muller et al. (2005) para simular fraturas. Em Muller et al., os vértices da superfície do objeto são tratados como partículas, sujeitas a forças externas ao objeto e a uma forçainterna de restituição, que tenta restaurar a forma do objeto através de uma técnica de casamen

5. A technique for interactive shape deformation on non-structured objects / Uma técnica para deformação interativa de objetos não estruturados
Este trabalho apresenta uma técnica para deformação interativa de objetos 3D não estruturados que combina o uso de sketches em 2D e manipulação interativa de curvas. Através de sketches no plano de imagem, o usuário cria curvas paramétricas a serem usadas como manipulares para modificar a malha do objeto. Um conjunto de linhas desenhadas sobre a pro

6. Influence of processing-induced phase transformations on the dissolution of theophylline tablets
The object of this investigation was to evaluate the influence of (1) processing-induced decrease in drug crystallinity and (2) phase transformations during dissolution, on the per-formance of theophylline tablet formulations. Anhydrous theophylline underwent multiple transformations (anhydrate »hydrate»anhydrate) during processing. Although the crystallin
