L’epoca delle splines: geometrie e linee del progetto contemporaneo
L’iconografia dell’architettura e del design di ogni epoca si caratterizza per l’uso di linee e di forme geometriche che vengono rese realizzabili dall’evoluzione dei materiali e delle tecniche costruttive, nonché dall’introduzione di particolari ...

Analysis of the Flow Field from Connection Cones to Monolith Reactors
The connection cones between an exhaust pipe and an exhaust after-treatment system (EATS) will affect the flow into the first monolith. In this study, a new streamlined connection cone using non-uniform rational B-splines (NURBS) is applied to optimize ...

Powell-Sabin B-splines and unstructured standard T-splines for the solution of the Kirchhoff-Love plate theory exploiting Bézier extraction [PDF]
The equations that govern Kirchhoff–Love plate theory are solved using quadratic Powell–Sabin B-splines and unstructured standard T-splines. Bézier extraction is exploited to make the formulation computationally efficient.

Research on the S-shaped time-rounding series feedrate scheduling based on NURBS curve
The inconsistency between continuous feedrate scheduling and discrete interpolation of Non-Uniform Rational B-Splines (NURBS) curves as toolpath interpolation affects the interpolation accuracy and motion smoothness of computer numerical control (CNC ...

UTD computation for NURBS surfaces
S.669-672One of the main problems in computing the UTD surface diffracted fields on surfaces described by Non-Uniform Rational B-splines (NURBS) is due to the difficulty in determining the geodesic paths the electromagnetic waves takes along the surface.

NURBS-Based Isogeometric Analysis Method Application to Mixed-Mode Computational Fracture Mechanics [PDF]
An interaction integral method for evaluating mixed-mode stress intensity factors (SIFs) for two dimensional crack problems using NURBS-based isogeometric analysis method is investigated. The interaction integral method is based on the path independent J-
