A Deep Learning‐Based Approach to Characterize Skull Physical Properties: A Phantom Study

Journal of Biophotonics, Volume 18, Issue 1, January 2025.
We extracted various features from ultrasound signals using skull‐mimicking phantoms (including variation in thicknesses and porosity) and analyzed them using machine learning and deep learning models. The evaluation demonstrated that ML‐ and DL‐trained models could predict the physical characteristics of skull phantoms with reasonable accuracy for ...

Weakly nonlinear thermoacoustics for stacks with slowly varying pore cross-sections [PDF]

A general theory of thermoacoustics is derived for arbitrary stack pores. Previous theoretical treatments of porous media are extended by considering arbitrarily shaped pores with the only restriction that the pore cross-sections vary slowly in the ...

Adaptive Vibration Control of the Moving Cage in the 4 ×$\times$ 4 Hyperbolic PDE‐ODE Model of the Dual‐Cable Mining Elevator

IET Control Theory &Applications, Volume 19, Issue 1, January/December 2025.
This paper proposes an observer‐based adaptive output‐feedback boundary control to stabilize the vibrations of the moving cage of a dual‐cable mining elevator. This system is comprised of two mechanically jointed winding drums that drive the two cables through the floating sheaves to lift the cage.
