Mechanical Models for Hermite Interpolation on the Unit Circle

Mathematics, 2021
In the present paper, we delve into the study of nodal systems on the unit circle that meet certain separation properties. Our aim was to study the Hermite interpolation process on the unit circle by using these nodal arrays.

Sleep and cardiac autonomic modulation in older adults: Insights from an at‐home study with auditory deep sleep stimulation

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary The autonomic nervous system regulates cardiovascular activity during sleep, likely impacting cardiovascular health. Aging, a primary cardiovascular risk factor, is associated with cardiac autonomic disbalance and diminished sleep slow waves. Therefore, slow waves may be linked to aging, autonomic activity and cardiovascular health. However, it

Contact Force Estimation of Continuum Robots without Embedded Sensors: A Review

Advanced Intelligent Systems, Volume 8, Issue 3, March 2026.
This review surveys methods for estimating contact forces in continuum robots without embedded sensors. It explains why contact force matters, classifies force patterns, and groups existing methods into three approaches based on actuation, deformation, and environment information.

Hermite Interpolation Using Möbius Transformations of Planar Pythagorean-Hodograph Cubics

Abstract and Applied Analysis, 2012
We present an algorithm for C1 Hermite interpolation using Möbius transformations of planar polynomial Pythagoreanhodograph (PH) cubics. In general, with PH cubics, we cannot solve C1 Hermite interpolation problems, since their lack of parameters makes ...

Extended Jensen’s functional for diamond integral via Green’s function and Hermite polynomial

Journal of Inequalities and Applications, 2022
In this paper, with the help of Green’s function and Hermite interpolating polynomial, an extension of Jensen’s functional for n-convex functions is deduced from Jensen’s inequality involving diamond integrals.

Multiple Refinable Hermite Interpolants

Journal of Approximation Theory, 2000
We consider solutions of a system of refinement equations written in the form as \(\varphi(x)= \sum_{n\in \mathbb{Z}}a(n) \varphi(2x-n)\), where \(\varphi= (\varphi_1, \dots, \varphi_r)^T\) is a vector of compactly supported functions on \(\mathbb{R}\) and \(a\) is a finitely supported sequence of \(r\times r\) matrices called the refinement mask. If \(

An adaptive scheme for the optimization of damping positions by decoupling controllability spaces in vibrational systems

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 3, March 2026.
Abstract In this work, the problem of optimizing damper positions in vibrational systems is investigated. The objective is to determine the positions of external dampers in such a way that the influence of the input on the output is minimized. The energy response serves as an optimization criterion, whose computation involves solving Lyapunov equations.

Empirical Results on the Magnetic Prandtl Number in the Slow Solar Wind Based on In Situ Measurements

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract The magnetic Prandtl number in the slow solar wind is estimated by using magnetic and velocity Reynolds numbers. The Prandtl number quantifies the ratio of kinetic to magnetic diffusion rates in a plasma, and indicates which process dominates the transport dynamics in a fluid.
