An Analysis of Deterministic Chaos as an Entropy Source for Random Number Generators
This paper presents an analytical study on the use of deterministic chaos as an entropy source for the generation of random numbers. The chaotic signal generated by a phase-locked loop (PLL) device is investigated using numerical simulations.

Chaos and Dynamics Induced by the Amplitude of Load Torque: Analysis and Control
In this contribution, the dynamics and chaos control of a permanent magnet reluctance synchronous motor (PMSM) with constant, sinusoidal, and square load torque taking the reference rotor speed and the stator voltage on d-q-axis are analyzed.

Analysis of Chaotic Dynamics by the Extended Entropic Chaos Degree
The Lyapunov exponent is the most-well-known measure for quantifying chaos in a dynamical system. However, its computation for any time series without information regarding a dynamical system is challenging because the Jacobian matrix of the map ...

Towards global models near homoclinic tangencies of dissipative diffeomorphisms [PDF]
A representative model of a return map near homoclinic bifurcation is studied. This model is the so-called fattened Arnold map, a diffeomorphism of the annulus. The dynamics is extremely rich, involving periodicity, quasiperiodicity and chaos. The method

Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Study on Super-Twisting synchronization control of chaotic system based on U model
A U model based Super-Twisting synchronization control method for chaotic systems is proposed. The chaos control of chaotic systems is prescribed, then, based on the current research status of chaotic systems and some useful research results in nonlinear

Synchronization and chaos control in a periodically-forced, quasi-geostrophic, two-layer model of baroclinic instability [PDF]
Cyclic forcing on many timescales is believed to have a significant effect on various quasi-periodic, geophysical phenomena such as El Niño, the Quasi-Biennial Oscillation, and glacial cycles.

Tunable 3D‐Printed Static Mixers for Gradient Bioprinting With High Cell Viability
ABSTRACT The fabrication of native tissue‐like structures with gradual transitions in material properties, cell types, and growth factors remains a major challenge in biofabrication due to the lack of suitable methods. Mimicking the hierarchical organization of living tissues is essential for functional models, yet creating gradient, multimaterial ...

The Discrete Fractional Variable-Order Tinkerbell Map: Chaos, 0–1 Test, and Entropy
The dynamics of the Caputo-fractional variable-order difference form of the Tinkerbell map are studied. The phase portraits, bifurcation, and largest Lyapunov exponent (LLE) were employed to demonstrate the presence of chaos over a different fractional ...
