Motion Artifacts Removal from Measured Arterial Pulse Signals at Rest: A Generalized SDOF-Model-Based Time–Frequency Method [PDF]

open access: yesSensors
Motion artifacts (MA) are a key factor affecting the accuracy of a measured arterial pulse signal at rest. This paper presents a generalized time–frequency method for MA removal that is built upon a single-degree-of-freedom (SDOF) model of MA, where MA ...

Added value of patient-reported outcome measures (PROMs) after an acute stroke and early predictors of 90 days PROMs

open access: yesJournal of Patient-Reported Outcomes, 2022
Introduction Value-based health care represents a patient-centered approach by valuing Patient-Reported Outcome Measures (PROMs). Our aim was to describe the additional value of PROMs after an acute stroke over conventional outcome measures and to ...

HARMONIC POLYLOGARITHMS [PDF]

open access: yesInternational Journal of Modern Physics A, 2000
The harmonic polylogarithms (hpl's) are introduced. They are a generalization of Nielsen's polylogarithms, satisfying a product algebra (the product of two hpl's is in turn a combination of hpl's) and forming a set closed under the transformation of the arguments x=1/z and x=(1-t)/(1+t). The coefficients of their expansions and their Mellin transforms

An Improved Dingo Optimization Algorithm Applied to SHE-PWM Modulation Strategy

open access: yesApplied Sciences, 2022
This paper presents a modification to the dingo optimization algorithm (mDOA) to solve the non-linear set of equations of the selective harmonic elimination (SHE) control technique widely applied in multilevel inverters. In addition, said modification is

Harmonic knots [PDF]

open access: yesJournal of Knot Theory and Its Ramifications, 2016
The harmonic knot [Formula: see text] is parametrized as [Formula: see text] where [Formula: see text], [Formula: see text] and [Formula: see text] are pairwise coprime integers and [Formula: see text] is the degree [Formula: see text] Chebyshev polynomial of the first kind. We classify the harmonic knots [Formula: see text] for [Formula: see text] We

Scalar, Vector and Tensor Harmonics on the Three-Sphere [PDF]

open access: yes, 2017
Scalar, vector and tensor harmonics on the three-sphere were introduced originally to facilitate the study of various problems in gravitational physics. These harmonics are defined as eigenfunctions of the covariant Laplace operator which satisfy certain
