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 ...

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‐

The Discretization‐Corrected Particle Strength Method for the Barotropic Vorticity Equations
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.

Renaissance vaults: geometry, nurbs and computational opportunities for reconstruction
Creating an interpretative geometric representation of architectural shapes is crucial to learn the essence of any architecture, to preserve it and to hand it down through the ages to our descendants.

On two-field NURBS-based isogeometric formulation for incompressible media problems
This paper presents u-p mixed formulation relied on the framework of NURBS-based Isogeometric approach (IgA) for incompressible problems. In mixed method, displacement (velocity) field is approximated using NURBS basis functions with one order higher ...

AUTOMATIC CONSTRUCTION OF NURBS SURFACES FROM UNORGANIZED POINTS
El modelamiento con Superfi cies B-Splines Racionales no Uniformes (NURBS) se ha convertido en un estándar en los sistemas CAD/CAM debido a su estabilidad, fl exibilidad y propiedades de modifi cación local. Las ventajas de ajustar con superfi cies NURBS

Abstract Computational fluid dynamics (CFD) has become an essential tool for studying fluid interactions in biological systems. While widely used in engineering, its application in the natural sciences, particularly in paleobiology, remains limited due to the challenges of meshing complex organic geometries.

A locking-free quadratic nurbs-based isogeometric formulation for plates analysis
A new Reissner-Mindlin plate formulation based on a quadratic NURBS-based isogeometric is presented. In order to avoid the transverse shear locking and to improve the accuracy of the present formulation, the quadratic NURBS-based isogeometric is ...

Watermarking Algorithms for 3D NURBS Graphic Data
Two watermarking algorithms for 3D nonuniform rational B-spline (NURBS) graphic data are proposed: one is appropriate for the steganography, and the other for watermarking.
