IGA-based Multi-Index Stochastic Collocation for random PDEs on arbitrary domains
, 2019 This paper proposes an extension of the Multi-Index Stochastic Collocation (MISC) method for forward uncertainty quantification (UQ) problems in computational domains of shape other than a square or cube, by exploiting isogeometric analysis (IGA ...

Advanced Engineering Materials, Volume 27, Issue 22, November 2025.Cubic Bézier curves are used in the synthesis of novel surface‐based metamaterials with tunable mechanical properties. Surface‐based geometries are 3D printed and tested in compression. The resulting mechanical properties are correlated to changes in the shape of the base curve, with high potential in energy absorption through the adjustment of their ...

The Anatomical Record, Volume 308, Issue 11, Page 2962-2975, November 2025.Abstract Saber‐tooths, extinct apex predators with long and blade‐like upper canines, have appeared iteratively at least five times in the evolutionary history of vertebrates. Although saber‐tooths exhibit a relatively diverse range of morphologies, it is widely accepted that all killed their prey using the same predatory behavior. In this study, we CT‐

An efficient bivariate three-point Lagrange interpolation method based on coordinate transformation
Advances in Mechanical EngineeringThis paper proposes a bivariate three-point interpolation method based on coordinate transformation. The transformation significantly improves computational efficiency by converting radial sampling points into interpolation nodes, while enabling high ...

A novel updating modelling methodology for free-form surface modifications in the early stages of design [PDF]
, 2003 The paper describes the first implementation of a method in which an initial CAD model is updated from a physical model. The method is based on image-mapping in which an initial CAD model is updated from images of a soft rapid prototype model (RPM) which

The Discretization‐Corrected Particle Strength Method for the Barotropic Vorticity Equations
International Journal for Numerical Methods in Fluids, Volume 97, Issue 11, Page 1426-1440, November 2025.Numerical solution for the barotropic vorticity equation in complex geometry using the meshless point collocation method. The spatial domain is represented by a set of nodes. The collocation method numerically solves the strong form governing equations.
