Invisibility and inverse problems [PDF]
We describe recent theoretical and experimental progress on making objects invisible. Ideas for devices that would have once seemed fanciful may now be at least approximately realized physically, using a new class of artificially structured materials, metamaterials . The equations that govern

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions
This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...

Row stochastic inverse eigenvalue problem
In this paper, we give sufficient conditions or realizability criteria for the existence of a row stochastic matrix with a given spectrum Λ = {λ1, ..., λn} = Λ1 ∪ ⋯ ∪ Λm ∪ Λm+1, m > 0; where (pk ...

A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Feedback methods for inverse simulation of dynamic models for engineering systems applications [PDF]
Inverse simulation is a form of inverse modelling in which computer simulation methods are used to find the time histories of input variables that, for a given model, match a set of required output responses.

Stability of solutions for some inverse problems
In this article we establish three stability results for some inverse problems. More precisely we consider the following boundary value problem: $Delta u + lambda u + mu = 0$ in $Omega$, $u = 0$ on $partialOmega$, where $lambda$ and $mu$ are real ...
