Abstract: The current paper is concerned with the controllability of nonlocal secondorder impulsive neutral stochastic functional integro-differential equations with infinite delay and Poisson jumps in Hilbert spaces. Using the theory of a strongly continuous cosine family of bounded linear operators, stochastic analysis theory and with the help of the Banach fixed point theorem, we derive a ne...

Keywords: Neutral delayed differential equation Double Hopf bifurcation Normal form Multiple time scales Center manifold reduction a b s t r a c t In this paper, we study dynamics in a container crane model with delayed position feedback , with particular attention focused on non-resonant double Hopf bifurcation. By using multiple time scales and center manifold reduction methods, we obtain the...

Sensitivity analysis is crucial both in the modeling phase and in the interpretation of model predictions. It contributes to model development, model calibration, model validation, reliability and robustness analysis, decision-making under uncertainty, and model reduction. Sensitivity analysis is concerned with the study of the relationship between infinitesimal changes in the model parameters ...
