Omega, modelo de formulação não linear dos processos hidrológicos
Hydrologic models, in general, perform a linearization of non-linear phenomena in such a way that the model becomes a simply parametric and numeric formulation. lnstead of that, OMEGA uses a more consistent mathematical representation of the physical processes in a hydrologic system. OMEGA model is …

Aplicabilidade de uma máquina teste eletrodinâmica a molas não lineares
An eletrodynamic system for testing fatigue in springs is represented by a model which has two degrees of freedom. The simulation of the tester by a two degrees af freedom system with restoring force F =(α+βx²)x is made on an analog computer EAI – TR48 DES – 30. The favorable values of the spring …

Análise, estudos paramétricos e projeto de um servomechanismo pneumático
A non-linear mathernatical model is developed to describe the dynarnic response of a class of pneumatic actuators. Pararnetric studies were conducted using digital simulation. Different types of input signals were used to actuate the pneurnatic servo. A linearized rnodel is constructed and compared …

Modêlos não lineares do sistema respiratório
This work is based on the mathematical of the respiratory system, in which not only a law of the proportional plus derivative type is proposed, but also the concept of singular points of the types, saddle and unstable focus, to form the limit cycle to explain the behaviour cyclical of the system. …
