Analysis of transient viscoelastic response of asphalt concrete using frequency domain approach

open access: yesJournal of Traffic and Transportation Engineering (English ed. Online), 2015
The analysis of transient linear viscoelastic response of asphalt concrete (AC) is important for engineering applications. The traditional transient response of AC is analyzed in the time domain by performing complicated convolution integral.

Random cones in high dimensions I: Donoho-Tanner and Cover-Efron cones

open access: yesDiscrete Analysis, 2022
Random cones in high dimensions I: Donoho-Tanner and Cover-Efron cones, Discrete Analysis 2020:5, 44 pp. As its title makes clear, this paper is about random high-dimensional cones. A _cone_ in $\mathbb R^d$ is a subset that is closed under addition and

On matrix representations of oversemigroups of semigroups generated by two mutually annihilating idempotents

open access: yesНауковий вісник Ужгородського університету. Серія: Математика і інформатика, 2020
Matrix representations of finite semigroups over fields are studied not so well as for finite groups. Representations of finite groups over fields are studied sufficiently well; in particular, the criterions of representation type are fully defined for ...

Dynamics of Potential Functionality of Objects

open access: yesFoundations of Management, 2019
This article guides the reader through the seemingly simple issues of the assessment, protec-tion and transfer of the potentials of an object’s functionality through its internal and external buffers, by employing Cartesian multiplication and signatures.

Problems and solutions in calculating quality-adjusted life years (QALYs)

open access: yesHealth and Quality of Life Outcomes, 2003
The quality-adjusted life-year (QALY) is a measure of the value of health outcomes. Since health is a function of length of life and quality of life, the QALY was developed as an attempt to combine the value of these attributes into a single index number.

A note on the generator subgraph of a graph

open access: yesElectronic Journal of Graph Theory and Applications, 2020
Graphs considered in this paper are  finite simple undirected graphs. Let G = (V(G), E(G)) be a graph with E(G) = {e1, e2,..., em}, for some positive integer m. The edge space of G, denoted by ℰ(G), is a vector space over the  field ℤ2. The elements of ℰ(

On cap sets and the group-theoretic approach to matrix multiplication

open access: yesDiscrete Analysis, 2017
On cap sets and the group-theoretic approach to matrix multiplication, Discrete Analysis 2017:3, 27pp. A famous problem in computational complexity is to obtain a good estimate for the number of operations needed to compute the product of two $n\times n$

Analysis of diversity using simple sequence repeat (SSR): distinctions between original Parmentiera cereifera tree and somaclones

open access: yesBulletin of the National Research Centre, 2018
Background The possibility of culturing Parmentiera cereifera in vitro was tested. Shoot tips and lateral buds were cultured in three media that were based on Murashige and Skoog (MS) but supplemented with different types and concentrations of growth ...
