Variable structure model for flow-induced tonal noise control with plasma actuators

, 2008
The objective of this work was to study the effect of plasma actuators in attenuating low-speed flow-induced cavitytones from a control point of view by employing techniques from classical control. A modification of the existingphysics-based linear model

Review of Electrohydraulic Actuators inspired by the HASEL Actuator

Biomimetics
The muscle-like movement and speed of the electrohydraulic actuator have granted it much at-tention in soft robotics. Our aim is to review the advancements in electrohydraulic actuators in-spired by the Hydraulically Amplified Self-healing Electrostatic (HASEL) actuator.

Symbolic Regression and Multi‐Objective Optimization of the Flory–Huggins Interaction Parameter for Hydrogels

Advanced Engineering Materials, EarlyView.
We develop a data‐driven method to derive the mathematical expressions of the Flory–Huggins interaction parameter χ for the swelling behavior of temperature–responsive hydrogels. Starting from initial assumptions of χ, our workflow combines Bayesian optimization, Flory–Rehner theory, and symbolic regression to generate candidate χ expressions.
