Nonlinear Reduced Order Modelling of Soil Structure Interaction Effects via LSTM and Autoencoder Neural Networks [PDF]

arXiv, 2022
In the field of structural health monitoring (SHM), inverse problems which require repeated analyses are common. With the increase in the use of nonlinear models, the development of nonlinear reduced order modelling techniques is of paramount interest. Of considerable research interest, is the use of flexible and scalable machine learning methods which

Effect of Random Parameter Switching on Commensurate Fractional Order Chaotic Systems

, 2016
The paper explores the effect of random parameter switching in a fractional order (FO) unified chaotic system which captures the dynamics of three popular sub-classes of chaotic systems i.e. Lorenz, Lu and Chen's family of attractors.

Self‐Oscillation in Active Wires with Asymmetric Willis‐Type Viscosity

Advanced Science, EarlyView.
This study suggests a self‐oscillation strategy enabled by a new set of material parameters, namely the asymmetric Willis‐type viscosity, to bias and independently control oscillation mode shapes as well as frequencies. The exemplified active wire can benefit the development of autonomous materials to construct soft motors, agitators, pumps, and ...

Protected Chaos in a Topological Lattice

Advanced Science, EarlyView.
Topological and chaotic dynamics are often considered incompatible, with one expected to dominate or disrupt the other. This work reveals that topological localization can persist even under strong chaotic dynamics and, counter‐intuitively, protect chaotic behavior.

Chaotic Griffiths Phase with Anomalous Lyapunov Spectra in Coupled Map Networks

, 2016
Dynamics of coupled chaotic oscillators on a network are studied using coupled maps. Within a broad range of parameter values representing the coupling strength or the degree of elements, the system repeats formation and split of coherent clusters.

Edge of Chaos Theory Unveils the First and Simplest Ever Reported Hodgkin–Huxley Neuristor

Advanced Electronic Materials, EarlyView.
This manuscript presents the first and simplest ever‐reported electrical cell, which leverages one memristor on Edge of Chaos to reproduce the three‐bifurcation cascade, marking the entire life cycle from birth to extinction via All‐to‐None effect of an electrical spike, also referred to as Action Potential, across axon membranes under monotonic ...

Materials Selection Principles for Designing Electro‐Thermal Neurons

Advanced Electronic Materials, EarlyView.
Materials property – performance relations are established for new and old electrical materials leveraged as electro‐thermal oscillators emulating neuron dynamics. Robust, reconfigurable, high frequency, low power characteristics are explicitly tied to highly nonlinear electrical transport, small specific heat, and greater electrical than thermal ...

Sound‐Based Assembly of Magnetically Actuated Soft Robots Toward Enhanced Release of Extracellular Vesicles

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Magnetic soft robots offer promise in biomedicine due to their wireless actuation and rapid response, but current fabrication methods are complex and have limited cellular compatibility. A new, contactless bioassembly strategy using hydrodynamic instabilities is introduced, enabling customizable, centimeter‐scale robots.

Chaos and flights in the atom-photon interaction in cavity QED

, 2002
We study dynamics of the atom-photon interaction in cavity quantum electrodynamics (QED), considering a cold two-level atom in a single-mode high-finesse standing-wave cavity as a nonlinear Hamiltonian system with three coupled degrees of freedom ...
