Chaos-based communication scheme using proportional and proportional-integral observers [PDF]
, 2008 In this paper, we propose a new chaos-based communication scheme using the observers. The novelty lies in the masking procedure that is employed to hide the confidential information using the chaotic oscillator.

High Speed Chaos in Optical Feedback System with Flexible Timescales
, 2003 We describe a new opto-electronic device with time-delayed feedback that uses a Mach-Zehnder interferometer as passive nonlinearity and a semiconductor laser as a current-to-optical-frequency converter.

How An Inventory Cost Misinterpretation Led To Chaos For Purchasing And Operations In A LEAN System
Journal of Business Case Studies (JBCS), 2011 A firm engaging in lean production has employed a computer system to revise order quantities and lot sizes in real time. What appears to be a minor misinterpretation of costs leads to radical fluctuations in inventory and efficiency. Volumes of resources and products grow, contrary to the intent of the system and drastic action is taken to reduce ...

Quantum computer inverting time arrow for macroscopic systems [PDF]
, 2001 A legend tells that once Loschmidt asked Boltzmann on what happens to his statistical theory if one inverts the velocities of all particles, so that, due to the reversibility of Newton's equations, they return from the equilibrium to a nonequilibrium ...

Bifurcation Dodge: Avoidance of a Thermoacoustic Instability under Transient Operation
, 2018 Varying one of the governing parameters of a dynamical system may lead to a critical transition, where the new stable state is undesirable. In some cases, there is only a limited range of the bifurcation parameter that corresponds to that unwanted ...
