COMPARISON OF B-SPLINE AND TRUNCATED SPLINE REGRESSION MODELS FOR TEMPERATURE FORECAST

Barekeng, 2023
The spline regression model is a nonparametric model and it is applied to data that do not have a certain curve shape and do not have information about it.

Simulation and Verification of Involute Spline Tooth Surface Wear before and after Carburizing Based on Energy Dissipation Method

Machines, 2023
This work studies the tooth surface wear of floating involute spline couplings. Based on the energy dissipation method, this study takes the floating involute spline couplings as the research object, divides the whole wear cycle into three wear stages ...

Prediction and Experimental Validation of Aviation Floating Involute Spline

Lubricants, 2022
Based on the research on the wear mechanism of floating involute spline coupling, combined with the traditional Archard wear equation, a wear prediction model of aviation floating involute spline coupling was established.

D-splines: Estimating rate schedules using high-dimensional splines with empirical demographic penalties

Demographic Research, 2021
Background: High-dimensional parametric models with penalized likelihood functions strike a good balance between bias and variance for estimating continuous age schedules from large samples. The penalized spline (P-spline) approach is particularly useful

V-Spline: An Adaptive Smoothing Spline for Trajectory Reconstruction

Sensors, 2021
Trajectory reconstruction is the process of inferring the path of a moving object between successive observations. In this paper, we propose a smoothing spline—which we name the V-spline—that incorporates position and velocity information and a penalty ...

Spline Approximation, Part 2: From Polynomials in the Monomial Basis to B-splines—A Derivation

Mathematics, 2021
In a series of three articles, spline approximation is presented from a geodetic point of view. In part 1, an introduction to spline approximation of 2D curves was given and the basic methodology of spline approximation was demonstrated using splines ...

Quadratic B-Spline Surfaces with Free Parameters for the Interpolation of Curve Networks

Mathematics, 2022
In this paper, we propose a method for constructing spline surfaces interpolating a B-spline curve network, allowing the presence of free parameters, in order to model the interpolating surface.
