Missing RRI Interpolation Algorithm based on Locally Weighted Partial Least Squares for Precise Heart Rate Variability Analysis [PDF]

open access: yesSensors, 2018
The R-R interval (RRI) fluctuation in electrocardiogram (ECG) is called heart rate variability (HRV), which reflects activities of the autonomic nervous system (ANS) and has been used for various health monitoring services.

A local identification method for linear parameter-varying systems based on interpolation of state-space matrices and least-squares approximation

open access: yesMechanical Systems and Signal Processing, 2017
This paper proposes a novel state-space matrix interpolation technique to generate linear parameter-varying (LPV) models starting from a set of local linear time-invariant (LTI) models estimated at fixed operating conditions. Since the state-space representation of LTI models is unique up to a similarity transformation, the state-space matrices need to

Comparison of Moving Least Squares and RBF+poly for Interpolation and Derivative Approximation [PDF]

open access: yesJournal of Scientific Computing, 2019
The combination of polyharmonic splines (PHS) with high degree polynomials (PHS+poly) has recently opened new opportunities for radial basis function generated finite difference approximations. The PHS+poly formulation, which relies on a polynomial least

Optimal Design of Thinned Array Using a Hybrid Genetic Algorithm [PDF]

open access: yesJournal of Electromagnetic Engineering and Science, 2021
In this paper, a hybrid genetic algorithm (GA) is proposed for thinning a two-dimensional planar array by combining the conventional GA with moving least squares (MLS). This enhances the convergence rate and the global search performance.
