Analysis of the nonlinear dynamics of a single pendulum driven by a magnetic field using the magnetic charges interaction model and the experimentally fitted interaction model
Bonaventure Nana, Krystian Polczyński, Paul Woafo +2
In this work, we analyzed theoretically and experimentally the nonlinear dynamics of a magnetic pendulum driven by a coil-magnet interaction. The force between the magnetic element…
Secondary frequency control stabilizing voltage dynamics
Eder Batista Tchawou Tchuisseu, Eric-Donald Ndogmo, Pavel Procházka +3
The ongoing energy transition challenges the stability of the electrical power system. Stable operation of the electrical power grid requires both the voltage (amplitude) and the f…
Chaotic dynamics of piezoelectric mems based on maximal Lyapunov exponent and Smaller Alignment Index computations
M. V. Tchakui, P. Woafo, Ch. Skokos
We characterize the dynamical states of a piezoelectric microelectromechanical system (MEMS) using several numerical quantifers including the maximal Lyapunov exponent, the Poincar…
Amplitude Stochastic Response of Rayleigh Beams to Randomly Moving Loads
L. M. Anague Tabejieu, B. R. Nana Nbendjo, G. Filatrella +1
We consider the problem of the nonlinear response of a Rayleigh beam to the passage of a train of forces moving with stochastic velocity. The Fourier transform and the theory of re…
Robustness of continuous-variable entanglement via geometrical nonlinearity
Philippe Djorwé, S. G. Nana Engo, Paul Woafo
We propose a scheme to generate robust stationary continuous-variable entanglement in optomechanical systems, based on geometrical nonlinearity that occurs for large mechanical dis…
Limiting effects of geometrical and optical nonlinearities on the squeezing in optomechanics
P. Djorwé, S. G. Nana Engo, J. H. Talla Mbé +1
In recent experiments, the re-thermalization time of the mechanical resonator is stated as the limiting factor for quantum applications of optomechanical systems. To explain the or…
Quantum associative memory with improved distributed queries
J. -P. Tchapet Njafa, S. G. Nana Engo, Paul Woafo
The paper proposes an improved quantum associative algorithm with distributed query based on model proposed by Ezhov et al. We introduce two modifications of the query that optimiz…
Intercellular spiral waves of calcium in a two dimensional network of cells
Wilfred D. Kepseu, Paul Woafo, H. Sakaguchi
It is shown, by means of numerical simulations, that intercellular spiral waves of calcium can be initiated in a network of coupled cells as a result of a de-synchronization betwee…
