Open‐Window Mapping for Accessory Pathway Ablation: Influence of Catheter Design on Mapping Performance [PDF]

Journal of Arrhythmia
Background Open‐window mapping (OWM) using the extended early‐meets‐late (EEML) algorithm is widely used for accessory pathway (AP) localization. However, the impact of catheter design on mapping performance and procedural outcomes remains unclear ...

Design of Biorthogonal Wavelets based on Spline and Spline-like Functions for Image Compression

International Journal of Emerging Research in Engineering, Science, and Management, 2022
Wavelet theory inspired from Fourier analysis is based on the basis function and its properties. Different wavelets use different basis functions which may better suit to some applications.

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 ...

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
