Probabilistic Identification of Parameters in Dynamic Fracture Propagation

International Journal for Numerical Methods in Engineering, Volume 127, Issue 4, 28 February 2026.
ABSTRACT In this paper, we propose a novel multiphase approach for identifying input parameters in dynamic fracture propagation. Often, such parameters are partially known and uncertain with incomplete input data, resulting in challenges in predicting a reliable dynamic failure response.

A Semi‐Analytical Gaussian Beam Summation Method to Compute the RCS of Dielectric and Dielectric‐Coated Targets in Mono or Bi‐Static Configurations

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
In this article, we provide a Gaussian beam‐based method to compute the RCS of dielectric and dielectric‐coated targets in both the monostatic and bistatic cases. ABSTRACT This study proposes to extend and refine the methodology of Gaussian beam summation (GBS) for computing the radar cross section (RCS) of dielectric targets in both monostatic and ...

Meteorological Tsunamis: From Local Hazard to Global Relevance

Reviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract Research on meteorological tsunamis or meteotsunamis—long ocean waves in the tsunami frequency band generated by propagating atmospheric disturbances which resonantly enhance ocean waves—has grown significantly in recent decades. This expansion is due to progress in (a) ocean and atmospheric measurements, including advanced instrumentation ...

A non-intrusive reduced-order modeling method using polynomial chaos expansion

, 2019
We propose a non-intrusive reduced-order modeling method based on proper orthogonal decomposition (POD) and polynomial chaos expansion (PCE) for stochastic representations in uncertainty quantification (UQ) analysis. Firstly, POD provides an optimally ordered basis from a set of selected full-order snapshots. Truncating this optimal basis, we construct
