SEPARATION OF DIFFRACTION SPECTRA BY PRINCIPAL COMPONENT METHOD BY THE EXAMPLE OF ARIFON DRUG

Российский технологический журнал, 2019
The article deals with the results of experimental studies on statistical processing of diffraction spectra of solid drugs for the purpose of their separation and identification. Diffractograms of the original and falsified drugs Arifon were used for the

Modified Kleene Star Algorithm Using Max-Plus Algebra and Its Application in the Railroad Scheduling Graphical User Interface

Computation, 2023
In max-plus algebra, some algorithms for determining the eigenvector of irreducible matrices are the power algorithm and the Kleene star algorithm. In this research, a modified Kleene star algorithm will be discussed to compensate for the disadvantages ...

Direction of Arrival Estimation Method Based on Eigenvalues and Eigenvectors for Coherent Signals in Impulsive Noise

Mathematics
In this paper, a Toeplitz construction method based on eigenvalues and eigenvectors is proposed to combine with traditional denoising algorithms, including fractional low-order moment (FLOM), phased fractional low-order moment (PFLOM), and correntropy ...

A method for suppressing resonance response of a vibration system coupled by springs

Nihon Kikai Gakkai ronbunshu, 2019
Since interior noise of an electric vehicle driven by motor has no engine noise, the contribution of the road induced noise at the low-middle vehicle speed range is higher and the noise is more noticeable for passengers compared to a conventional ...

Analytical solutions to some generalized and polynomial eigenvalue problems

Special Matrices, 2021
It is well-known that the finite difference discretization of the Laplacian eigenvalue problem −Δu = λu leads to a matrix eigenvalue problem (EVP) Ax =λx where the matrix A is Toeplitz-plus-Hankel.

Scanner-Independent Calibrations of Handheld Near-Infrared Spectra for Robust Quality Assessment of Vanilla Pods

Journal of Food Quality
Vanillin is a high-value flavor compound derived from Vanilla planifolia, whose grading in commercial supply chains remains challenging due to compositional heterogeneity of the pods and variability among handheld near-infrared (NIR) scanners.
