Exponential Splines of Complex Order
, 2013 We extend the concept of exponential B-spline to complex orders. This extension contains as special cases the class of exponential splines and also the class of polynomial B-splines of complex order.

Scalable low-complexity B-spline discretewavelet transform architecture [PDF]
, 2010 A scalable discrete wavelet transform architecture based on the B-spline factorisation is presented. In particular, it is shown that several wavelet filters of practical interest have a common structure in the distributed part of their B-spline ...

B-spline snakes in two stages [PDF]
, 2004 In using Snake algorithms, the slow convergence speed is due to the large number of control points to be selected, as well as difficulties in setting the weighting factors that comprise the internal energies of the curve.

Arthritis Care &Research, EarlyView.Objective Reports have linked both high and low serum uric acid (SUA) levels to adverse health outcomes. This study aimed to establish a reference interval for SUA in older adults and assessed its association with clinically relevant outcomes in relatively healthy, community‐dwelling individuals aged ≥70 years old.

On the limits of non-uniform rational B-spline surfaces with varying weights
Advances in Mechanical Engineering, 2017 The non-uniform rational B-spline is a mathematical model commonly used in computer-aided design and manufacturing. For a non-uniform rational B-spline surface, when a single weight approaches infinity, the surface tends to the corresponding control ...

Automatic, computer aided geometric design of free-knot, regression splines [PDF]
, 2004 A new algorithm for Computer Aided Geometric Design of least squares (LS) splines with variable knots, named GeDS, is presented. It is based on interpreting functional spline regression as a parametric B-spline curve, and on using the shape preserving ...

An advanced variant of an interpolatory graphical display algorithm [PDF]
, 2004 In this paper an advanced interpolatory graphical display algorithm based on cardinal B-spline functions is provided. It is well-known that B-spline functions are a flexible tool to design various scale rapresentations of a signal.

Neutrosophic B-spline Surface Approximation Model for 3-Dimensional Data Collection [PDF]
Neutrosophic Sets and SystemsSince there are threei membershipi functions: truth, false, and indeterminacyi, geometrical modelingi for B-spline surface approximation including neutrosophic data is particularly difficult to construct.
