Axioms, 2015 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 ...

A rational cubic spline with tension [PDF]
, 1989 A rational cubic spline curve is described which has tension control parameters for manipulating the shape of the curve. The spline is presented in both interpolatory and rational B-spline forms, and the behaviour of the resulting representations is ...

microRNA-7-5p and α-Synuclein SAA Predict Parkinson's Disease Phenoconversion. [PDF]
Ann Clin Transl NeurolABSTRACT Objective Corroborate blood neuron‐derived extracellular vesicle (NDEV) alpha‐synuclein (αSyn), the CSF αSyn seed amplification assay (αSyn‐SAA), and blood microRNA‐7‐5p (miR‐7‐5p) as markers for Parkinson's disease (PD) phenoconversion and determine if combining these markers would help select subjects who would be more likely to phenoconvert.

The weighted v-spline as a double knot B-spline [PDF]
, 1991 The local support basis representation of the ‘weighted v-spline’ is derived in terms of double knot cubic B-splines, so providing a convenient form for computing and analysing the ...

Two-stage spline-approximation in linear structure routing
Российский технологический журнал, 2021 In the article, computer design of routes of linear structures is considered as a spline approximation problem. A fundamental feature of the corresponding design tasks is that the plan and longitudinal profile of the route consist of elements of a given ...

Evaluation of Different Spatial Interpolation Methods for IMERG Precipitation Zoning in Neyshabur Basin [PDF]
Journal of Hydraulic and Water Engineering, 2023 Direct measurement of continuous spatial data is almost impossible due to the limitations in data collection. To address this issue, many methods have been proposed for data interpolation.

Cubic spline interpolation of harmonic functions [PDF]
, 1973 It is shown that for the two dimensional Laplace equation a univariate cubic spline approximation in either space direction together with a difference approximation in the other leads to the well-known nine-point finite-difference formula.
