This paper introduces a kind of new wavelet radiosity method called multiresolution B-spline radiosity, which uses B-splines of different scales to represent radiosity distribution functions. A set of techniques and algorithms, such as function extrapolation, adaptive quadrature, scale adjustment and oct...
B‐spline basis functions for moment‐method analysis of axisymmetric reflector antennas 来自 Semantic Scholar 喜欢 0 阅读量: 12 作者: Fernando L. Teixeira,José R. Bergmann 摘要: The use of cubic B splines is investigated in connection with the method‐of‐moments (MoM) analysis of axially ...
This article presents two new methods for adaptive refinement of a B-spline finite element solution within an integrated mechanically based computer aided engineering system. The proposed techniques for adaptively refining a B-spline finite element solution are a local variant of np-refinement and a ...
2.2. B-spline As Bezier curves cannot be modified locally and the movement of the control points will affect the whole curve shape [13], hence, the researchers try to solve the problems. Finally, B-spline method has been generalised from Bezier method to overcome the problems faced and it ...
The B-spline curve-generating technique has been used in the study. This is an efficient method for geometrical modelling of the deformation diffusion areas formed after the drop test. Proper control points have been chosen to be able to draw the borders of the diffusion areas on the fabric ...
Solution structures that are C 1 or C 2 continuous throughout the analysis domain can be constructed using B-spline basis functions. As a structured grid does not conform to the geometry of the analysis domain, the boundaries of the analysis domain are defined independently using equations of ...
B-spline finite element method which integrates geometric design and mechanical analysis of shell structures is presented. To link geometric design and analysis modules completely, the non-periodic cubic B-spline functions are used for the description of geometry and for the displacement interpolation fu...
This proposed method consists of 2 approaches: (1) using B‐spline fitting method to improve the deficiency of bistable system and (2) the genetic algorithm used to obtain the parameters of B‐spline bistable system. Then, a faulty line detection criterion (FLDC) based on BSBD and polarity ...

This paper proposes a novel approach based on the adaptive B-spline basis dictionary and sparse regularization technique for BIL identification. A representation of basis function is first established to construct BIL, and then integrated with a redundant B-spline basis dictionary to ensure the ...
