Surface catalytic reactions display under low pressure conditions non-linear features such as non-stationary reaction rates and spatio-temporal patterns known as dissipative structures. We analyze experimental data from ...

The objective of this paper is the numerical study of the behavior of reinforced concrete beams and columns by non-linear numerical simulations. The numerical analysis is based on the finite element method implemented in ...

The rheological behavior and stability of oil-in-water emulsions was studied. The addition of different thickening agents improved the stability of the emulsions, and the presence of hydrocolloids caused their flocculation. ...

Process scheduling techniques consider the current load situation to allocate computing resources. Those techniques make approximations such as the average of communication, processing, and memory access to improve the ...

In this work, a non-ideal system based on the Mathieu-Van der Pol System is modeled considering its parameters as uncertain, which makes it closer to reality. Numerical simulations are presented demonstrating that the ...

In this work, we use a nonlinear control based on Optimal Linear Control. We used as mathematical model a Duffing equation to model a supporting structure for an unbalanced rotating machine with limited power (non-ideal ...

Neste trabalho, consideramos o mapa Hassell e estudamos sobre a construção numérica do diagrama de órbitas, considerando valores diferentes dos parâmetros de controle, para avaliar o comportamento do sistema. Analisamos, ...

The use of piezoelectric materials in various applications, including the development of bio-inspired structures, vibration control, energy harvesting, among others, has been investigated by several researchers over the ...

Self-centering dissipating devices have been developed in the last decades to both mitigate seismic response and reduce residual drifts of structures. Recent large magnitude earthquakes have shown that most of the repair ...
