Chaotic semi-express buses in a loop

Open-loop frequency response for a chaotic masking system

In this paper, a new numerical simulation approach is proposed for the study of open-loop frequency response of a chaotic masking system. Using Chua's circuit and the Lorenz system as illustrative examples, we have shown that one can employ chaos synchronization to separate the feedback network from a chaotic masking system, and then use numerical simulation to obtain the open-loop synchronizat...

Fluctuation of riding passengers induced by chaotic motions of shuttle buses.

We study the fluctuation of the number of riding passengers in a few shuttle buses that pass each other freely. We present a dynamical model of the shuttle buses that takes into account the maximum capacity of a bus. The dynamics of the buses is expressed in terms of a coupled nonlinear map with noise. The number of passengers carried by a bus and the time headway between buses exhibit complex ...

No One Loop Back - Reaction In Chaotic Inflation

We use an invariant operator to study the quantum gravitational backreaction to scalar perturbations during chaotic inflation. Our operator is the inverse covariant d’Alembertian expressed as a function of the local value of the inflaton. In the slow roll approximation this observable gives −1/(2H2) for an arbitrary homogeneous and isotropic geometry, hence it is a good candidate for measuring ...
