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.

Simulation of Seismic Response of Reinforced Concrete Beam-Column Joints with Nurbs Surface Fitting
This paper presents an approach based on NURBS (non-uniform rational B-splines) to achieve a seismic response surface (SRS) from a group of points obtained by using an analytical model of RC joints.

An experimental study to test a 3D laser Scanner for body measurement and 3D virtual garment design in Fashion education [PDF]
Artists, scientists, anthropometrists and tailors have accurately measured the human body with traditional tools, such as tape measures, callipers and accumulated visceral experience for centuries. Due to the progressive acceleration in the quality of 3D

Surface Error Evaluation of Non-circular Bevel Gear of Variable Ratio Differential
Based on the data obtained from the three-coordinate measuring and pre-processing,a NURBS method to reconstruct the complex surface of non-circular bevel gear and a two-step matching method to implement the complex surface error evaluation is proposed ...

Inverse Relations for Blossoms and Parametrisations of Rational Curves and Surfaces
In this paper, we make use of an inverse formula that relates the blossom of a NURBS curve, surface or Bézier triangle with its parametrisation, with no explicit reference to the control points and weights of the parametrisation.
