Identification of Weakly Singular Relaxation Kernels in Three-Dimensional Viscoelasticity

Journal of Mathematical Analysis and Applications, 2001
The author is concerned with the following operator identification problem related to a Hilbert space \(X\), a Banach space \(Y\hookrightarrow X\) (densely) and to a closed subspace \(K\subset {\mathcal L}(X)\): determine a pair of functions \(u:(0,+\infty)\to X\) and \(M:(0,+\infty)\to K\) satisfying the equations \[ u''(t) = Au(t) - \int_0^t M(t-s)Bu(

A Versatile‐Designable Framework for Active and Programmable Shape‐Morphing Soft Matter Systems: From Inverse Design to Closed‐Loop Control

Advanced Science, EarlyView.
A versatile framework integrates addressable electrothermal actuation and strain‐constraint mechanisms to construct programmable shape‐morphing soft matter systems. By combining an analytical inverse design strategy for high‐fidelity 3D surface reconstruction with deep learning‐based closed‐loop control, this approach enables zero‐energy shape locking,

On the Lp-differentiability of certain classes of functions [PDF]

, 2014
We prove the $L^p$-differentiability at almost every point for convolution products on $R^d$ of the form $K*\mu$, where $\mu$ is bounded measure and $K$ is a homogeneous kernel of degree $1-d$.
