1. EFFICIENCY ASSESSMENT OF ADVANCED MODAL ANALYSIS AS COMPARED TO TECHNIQUES BASED ON NUMERICAL INVERSE TRANSFORMS / COMPARAÇÃO DO DESEMPENHO COMPUTACIONAL DA TÉCNICA DE SUPERPOSIÇÃO MODAL AVANÇADA COM TÉCNICAS DA TRANSFORMADA DE LAPLACE
An established technique to solve time-dependent problems is the formulation of a complete frequency-domain analysis via Laplace or Fourier transforms, with subsequent ad hoc expression of results by numerical inversion. Although usually easy to implement, such a transform inversion is computationally intensive, if accurate results are desired, and liable to

2. Atividade reprodutiva de Plagioscion squamosissimus (Heckel,1840) (Actinopterygii,Perciformes), no reservatório de Pedra, Rio de Contas, Bahia
We evaluated the reproductive aspects of the organization and characterization of oocytes and the maturational stages of Plagioscion squamosissimus in the reservoir of stone, river of Auditors, Bahia. The collections were bimonthly, conducted between november/04 and september/06. It was recorded during reproductive activity every year, with peaks in march/05

3. A DYNAMIC INTERACTION MODEL OF TRACK RAILWAY STRUCTURAL ELEMENTS / UM MODELO DE INTERAÇÃO DINÂMICA ENTRE OS ELEMENTOS ESTRUTURAIS DE UMA VIA FÉRREA
In a railway, the vehicle interacts dynamically with a track superstructure (rails, rail pad and sleepers) and sub-structure (ballast, sub-ballast, sub- grade). Passengers comfort, environmental loading (ground vibration) and frequency of maintenance works of vehicles as well as of the track are deter- mined by the way all the structural elements interact. T

4. DEVELOPMENT OF HYBRID FINITE ELEMENTS FOR ANALYSIS OF DYNAMICS PROBLEMS USING ADVANCED MODE SUPERPOSITION / DESENVOLVIMENTO DE ELEMENTOS FINITOS HÍBRIDOS PARA A ANÁLISE DE PROBLEMAS DINÂMICOS USANDO SUPERPOSIÇÃO MODAL AVANÇADA
The hybrid finite element method, proposed by Pian on the basis of the Hellinger-Reissner potential, has proved itself a conceptual breakthrough among the discretization formulations, and has been extensively explored both academically and in commercial codes also taking into account an independent series of more recent developments called Trefftz methods.
