A simple circuit realization of the tent map

, 2009
We present a very simple electronic implementation of the tent map, one of the best-known discrete dynamical systems. This is achieved by using integrated circuits and passive elements only. The experimental behavior of the tent map electronic circuit is

Shil'nikov Chaos control using Homoclinic orbits and the Newhouse region

, 2006
A method of controlling Shil'nikov's type chaos using windows that appear in the 1 dimensional bifurcation diagram when perturbations are applied, and using existence of stable homoclinic orbits near the unstable one is presented and applied to the ...

Synchronization by dynamical relaying in electronic circuit arrays [PDF]

, 2006
We experimentally study the synchronization of two chaotic electronic circuits whose dynamics is relayed by a third parameter-matched circuit, to which they are coupled bidirectionally in a linear chain configuration.

Optimized Time–Frequency Analysis for Induction Motor Fault Detection Using Hybrid Differential Evolution and Deep Learning Techniques

International Journal of Adaptive Control and Signal Processing, EarlyView.
Workflow of the parameter optimization process for ITSC fault detection, applying Differential Evolution optimization and the Smooth Pseudo Wigner‐Ville Distribution for signal processing. The optimized parameters are then used in the failure identification pipeline, which combines the signal processing with a YOLO‐based architecture for fault severity

Energy-Efficient Thermo-Optic Switches Enabled by 3D Glass-Based EIC–PIC Packaging for High-Density Photonic Switch Arrays

IEEE Photonics Journal
Thermo-optic (TO) switches are essential components in integrated photonic circuits (PICs), but their efficiency is limited by significant heat dissipation into the silicon substrate due to its high thermal conductivity.
