Simulation of a cubic-like Chua’s oscillator with variable characteristic

Simulation of a cubic-like Chua's oscillator with variable characteristic

An alternative version of Chua’s oscillator is obtained using a cubic-like nonlinearity [2], which is implemented with two CMOSFET transistors. We propose a modification of this implementation that allows to change the shape of the characteristic in an easy way. A mathematical model of the circuit is derived based on the equations of MOSFET transistors [3] and a Chua’s circuit is simulated usin...

Simulation of Characteristic of Linear Degradation with Failure Modes

Simulation and perturbation analysis of escape oscillator

The dynamical behaviour of the forced escape oscillator, which depends on the parameter values we considered, have been studied numerically using the techniques of phase portraits and Poincar'{e} sections. Also, we employed perturbation methods such as Lindstedt's method to obtain the frequency-amplitude relation of escape oscillator.

GPU-SPH simulation of Tsunami-like wave interaction with a seawall associated with underwater

Investigation of the waves generated by underwater disturbances gives precious insight into the effect of man-made underwater explosions as well as natural phenomena, such as underwater volcanoes or oceanic meteor impact. On the other hand, prediction of the effects of such waves on the coastal installations and structures is required for preparation worthwhile criteria for coastal engineers to...

Padé summability of the cubic oscillator

We prove the Padé (Stieltjes) summability of the perturbation series of the energy levels of the cubic anharmonic oscillator, H1(β) = p +x+ i p βx, as suggested by the numerical studies of Bender and Weniger. At the same time, we give a simple and independent proof of the positivity of the eigenvalues of the PT -symmetric operator H1(β) for real β (Bessis-Zinn Justin conjecture). All the n 2 N ...
