25. Analise de porticos metalicos planos com conexões semi-rigidas considerando a não linearidade fisica e geometrica
: In this work, utilizing numeric process, are presented analyses of plane steel frames, deformables by flexion and axial force. In this analyses, are considered the effects of the structure geometric nonlinearity, of the material physical nonlinearity associated to the behaviour of semi-rigid connections. Are presented the models to the consideration of the

27. Analise e dimensionamento de estruturas metalicas planas considerando a não linearidade geometrica e fisica
This work presents a formulation to consider the nonlinear effects in the structural ana/ysis of rigid plane frames. This formu/ation is based on the stability functions matrix method. The stability functions are obtained after solving the governing differential equations of the problem (assuming that strains are small and neglecting the axial deformation of

28. STRUCTURAL OPTIMIZATION OF PLANE FRAMES / OTIMIZAÇÃO ESTRUTURAL DE PÓRTICOS PLANOS
É desenvolvido um programa de computador para minimizar o peso de pórticos planos submetidos a carregamento no plano, sendo possível a consideração de várias hipóteses de carga. As estruturas sintetizadas satisfazem as especificações do AISC ¿ American Institute of Steel Construction que são usadas como restrições do problema de otimização. Fa

29. Tight frames of k-plane ridgelets and the problem of representing objects that are smooth away from d-dimensional singularities in Rn
For each pair (n, k) with 1 ≤ k < n, we construct a tight frame (ρλ : λ ∈ Λ) for L2 (Rn), which we call a frame of k-plane ridgelets. The intent is to efficiently represent functions that are smooth away from singularities along k-planes in Rn. We also develop tools to help decide whether k-plane ridgelets provide the desired efficient representation

30. Trichobothrial mediation of an aquatic escape response: Directional jumps by the fishing spider, Dolomedes triton, foil frog attacks
Fishing spiders (Pisauridae) frequent the surfaces of ponds and streams and thereby expose themselves to predation by a variety of aquatic and semi-aquatic vertebrates. To assess the possibility that the impressive jumps of fishing spiders from the water surface function in evading attacks by frogs, attacks by bullfrogs (Rana catesbiana) and green frogs (R.
