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.

Wavelength Calibration of Linear Array Spectrometers Using Cubic Hermite Spline Interpolation
Applied Spectroscopy PracticaWavelength calibration of linear array spectrometers is conventionally performed by fitting a polynomial function of pixels to calibration data consisting of spectral lines with known wavelengths and their pixel locations. Alternatively, a multiparameter

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.

PLoS ONE, 2015 Rotundone is a sesquiterpene that gives grapes and wine a desirable 'peppery' aroma. Previous research has reported that growing grapevines in a cool climate is an important factor that drives rotundone accumulation in grape berries and wine.

Piecewise Hermite interpolation via barycentric coordinates
, 2015 Piecewise interpolation methods, as spline or Hermite cubic interpolation methods, define the interpolating function by means of polynomial pieces and ensure that some regularity conditions hold at the break-points.

Electrocardiogram reconstruction based on Hermite interpolating polynomial with Chebyshev nodes
Electrocardiogram (ECG) signals generate massive volume of digital data, so they need to be suitably compressed for efficient transmission and storage. Polynomial approximations and polynomial interpolation have been used for ECG data compression where ...

, 2020 Numerical modelling of high frequency waves is a complex and challenging area. Although the underlying equation seems simple, −∆φ − k2φ = f, the numerical challenges are not. This time harmonic wave equation is known as the Helmholtz equation.

Smooth Multiwavelet Duals of Alpert Bases by Moment-Interpolating Refinement
, 2000 Using refinement subdivision techniques, we construct smooth multiwavelet bases for L2(R) and L2([0,1]) which are in an appropriate sense dual to Alpert orthonormal multiwavelets. Our new multiwavelets allow one to easily give smooth reconstructions of a

Applied Sciences, 2018 With an extension in service years, bridges inevitably suffer from performance deterioration. Columns are the main components of bridge structures, which support the superstructure. The damage of pier columns is often more harmful to bridges than that of
