We consider the bifurcation of periodic solutions from an equilibrium point of the given equation: x =F(x,?) , where x ? R , ? is a vector of real parameters ? , ? , ... , ? and F:R x R ->R has at least second continuous derivations in variables

In the present paper, a new 2-D Van der Polstructural oscillator model is introduced for the vortex induced vibrations of circular cylinders.The main purpose of this task is to control the recently introduced model by means of modern control definitions in state space. In order to control the system, the whole model is linearized about its equilibrium point by deriving state-space matrices. The...

This note examines equilibrium existence of Nash-Bertrand pricing games with discrete-choice models of demand. We provide a sufficient and necessary condition on the distribution of firm idiosyncratic shocks for best response correspondences to exhibit monotonicity. We then use Tarski’s fixed point result to show that the condition we provide generates a unique pure-strategy equilibrium. Moreov...

We propose a new approach for modeling congested transit networks with fixed time tables where it may happen that there is not enough room onboard to allow all users waiting for a given line on the arriving vehicle, so that passengers need to queue at the stop until the service becomes actually available to them. Indeed, to reproduce this phenomenon within the established framework of diachroni...

In this paper we introduce a new modeling paradigm for shortest path games representation with Petri nets. Whereas previous works have restricted attention to tracking the net using Bellman’s equation as a utility function, this work uses a Lyapunov-like function. In this sense, we change the traditional cost function by a trajectory-tracking function which is also an optimal cost-to-target fun...
