Second-order linear recurrences with identically distributed residues modulo pᵉ [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
Let p be an odd prime and let u(a,-1) and u(a',-1) be two Lucas sequences whose discriminants have the same nonzero quadratic character modulo p and whose periods modulo p are equal.

Identification and classification of honey's authenticity by attenuated total reflectance Fourier-transform infrared spectroscopy and chemometric method [PDF]

open access: yesVeterinary World, 2019
Background and Aim: The authentication of honey is important to protect industry and consumers from such adulterated honey. However, until now, there has been no guarantee of honey's authenticity, especially in Indonesia.

Application of ATR-FTIR Incorporated with Multivariate Data Analysis for Discrimination and Quantification of Urea as an Adulterant in UHT Milk

open access: yesFoods, 2023
Urea is naturally present in milk, yet urea is added intentionally to increase milk’s nitrogen content and shelf life. In this study, a total of 50 Ultra heat treatment (UHT) milk samples were spiked with known urea concentrations (0–5 w/v%).

Methodic of pedagogic control of 16-17 years’ age girls’ motor fitness

open access: yesPedagogics, Psychology, Medical-Biological Problems of Physical Training and Sports, 2016
Increase of schoolchildren’s motor fitness is connected with organization of pedagogic control at physical culture lessons. It was assumed that the basis for pedagogic control of 16-17 years’ age girls’ motor fitness was discriminant model.

Discriminant Formulas and Applications

open access: yes, 2016
We solve two conjectures of Ceken-Palmieri-Wang-Zhang concerning discriminants and give some applications.Comment: 33 pages. Edit: In version 2, we removed the hypothesis that 1-q is invertible in Theorem 0.

Iterated discriminants

open access: yesJournal of Symbolic Computation, 2009
In this paper the authors prove that the discriminant of the discriminant of a multivariate polynomial has the same irreducible factors of the product of seven polynomials. These seven polynomials are obtained as the GCD of the generators of an elimination ideal. This result is similar to the one by \textit{L. Busé} and \textit{B.

Modeling the boundaries of the working space of a planar three-link manipulator

open access: yesОмский научный вестник
A study of the boundaries of the working space of a three-link planar manipulator, specified by analytical equations, is carried out. A new geometric interpretation of these samples is proposed.
