1. Parametric analysis of a phenomenological model for vortex-induced motions of monocolumn platforms
Phenomenological models are an important branch in VIV (Vortex-Induced Vibrations) and in VIM (Vortex-Induced Motions) studies to complement the results achieved via CFD (Computational Fluid Dynamics), as the latter tool is not presently a suitable tool for intense use in engineering analysis, due to high computer power requirements. A phenomenological model

2. Modelo hidro-elástico para simular as vibrações induzidas por vórtices em cabos submersos. / Hidro-elastic model to stimulate vortex-induced vibrations in submerged cables.
The present work proposes a qualitative numerical study of a hydro-elastic model in order to simulate vortex-induced vibrations in submerged cables. The model is composed of a coupled system of equations describing the structure and the fluid. The structure is modeled through a classical elastic oscillator and discretized using a lumped mass approach. The fl

3. Modelagem ambiental de uma casa de vegetação utilizando rede de osciladores de Van Der Pol. / Greenhouse environmental modeling using Van Der Pol oscillator network.
Agricultural automation is an important area in the development of Brazilian production in recent years. Often, measurement and control of the internal conditions of greenhouses are not easy to implement at a reasonable cost. Researches in this area look for models using computational theory, foreseeing the behavior of internal variables of a greenhouse from

4. Study of the interaction between cardiac and respiratory system in the light of the theory of Shannon / Estudo da InteraÃÃo entre o Sistema Cardiovascular e o RespiratÃrio à Luz da Teoria da InformaÃÃo de Shannon
Estuda-se a dinÃmica do sistema cardiorespiratÃrio à luz da Teoria de Shannon. O estudo tem dois suportes metodolÃgicos, um à o estudo de dois osciladores de van der Pol acoplados de diferentes maneiras e o outro à a ferramenta estatÃstica, InformaÃÃo MÃtua, da Teoria da InformaÃÃo de Shannon. Faz-se, primeiramente, uma revisÃo da fisiologia dos
