Conventional splines offer powerful means for modeling surfaces and volumes in three-dimensional Euclidean space. A one-dimensional quaternion spline has been applied for animation purpose, where the splines are defined to model a one-dimensional ...

Splines with nonnegative 𝐵-spline coefficients [PDF]
We consider the question of the approximation of nonnegative functions by nonnegative splines of order k (degree > k > k ) compared with approximation by that subclass of nonnegative splines of order k consisting of all those whose B-spline coefficients are nonnegative; while approximation by the former gives ...

Methods to Apply a 3-Parameter Logistic Model to Wind Turbine Data
Power curves provided by wind turbine manufacturers are obtained under certain conditions that are different from those of real life operation and, therefore, they actually do not describe the behavior of these machines in wind farms.

Multilevel refinable triangular PSP-splines (Tri-PSPS) [PDF]
A multi-level spline technique known as partial shape preserving splines (PSPS) (Li and Tian, 2011) has recently been developed for the design of piecewise polynomial freeform geometric surfaces, where the basis functions of the PSPS can be directly ...

Filter design using data fusion for a pneumatic control valve [PDF]
This paper presents a filter design technique for a pneumatic valve using data fusion techniques. The objective of this paper is to examine the suppression of the effect of parameters causing deviation from normal system performance using the ...

THB-splines: The truncated basis for hierarchical splines [PDF]
The construction of classical hierarchical B-splines can be suitably modified in order to define locally supported basis functions that form a partition of unity. The authors show that this property can be obtained by reducing the support of basis functions defined on coarse grids, according to finer levels in the hierarchy of splines.

Asymptotics for penalized additive B-spline regression [PDF]
This paper is concerned with asymptotic theory for penalized spline estimator in bivariate additive model. The focus of this paper is put upon the penalized spline estimator obtained by the backfitting algorithm.

Analysis-suitable adaptive T-mesh refinement with linear complexity [PDF]
We present an efficient adaptive refinement procedure that preserves analysis-suitability of the T-mesh, this is, the linear independence of the T-spline blending functions.
