On the problem of cyclization of “Little Tragedies” by A. S. Pushkin [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Серия Филология, Журналистика, 2022
The article proposes a new version of the cycle-forming organization of “Little Tragedies” by A. S. Pushkin, after a brief excursion through the already existing cycle-forming concepts of a group of scenes and plays united in Russian culture under the ...

On The Investigating Cycle Properties In The Galilean Plane G^2

open access: yesEurasian Journal of Science and Engineering, 2023
The introduction of the Galilean plane within the affine plane parallels the familiar concepts of the Euclidean plane, extending the realm of geometric exploration.

THE STUDY OF ECCENTRICITY SPECTRUM AND ENERGY IN PATH AND CYCLE GRAPHS

open access: yesBarekeng, 2023
The eccentricity matrix is one of matrices to represent graphs. The eccentricity matrix is used as a basis for calculating the eccentricity spectrum and energy. This article aims to study the concepts of eccentricity spectrum and energy in simple graphs.

Cycles intersecting edge-cuts of prescribed sizes [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2005
We prove that every cubic bridgeless graph $G$ contains a $2$-factor which intersects all (minimal) edge-cuts of size $3$ or $4$. This generalizes an earlier result of the authors, namely that such a $2$-factor exists provided that $G$ is planar.

Biogeographical characterization of Psalmocharias plagifera (Schumacher, 1922) (Hemiptera: Cicadidae) mass emergence in southwest Morocco

open access: yesAfrican and Mediterranean Agricultural Journal - Al Awamia, 2023
Several zones in southwestern Morocco were surveyed following a recent exceptional invasion of a species of cicada in May 2021, which caused significant damage, particularly in young almond plantations. The objective is to identify the cicada causing the

The Modular Irregularity Strength of C_n⊙mK_1

open access: yesInPrime, 2022
Let G(V, E) be a graph with order n with no component of order 2. An edge k-labeling α: E(G) →{1,2,…,k} is called a modular irregular k-labeling of graph G if the corresponding modular weight function wt_ α:V(G) → Z_n defined by wt_ α(x) =Ʃ_(xyϵE(G)) α ...

AVD proper edge-coloring of some families of graphs

open access: yesInternational Journal of Mathematics for Industry, 2021
Adjacent vertex-distinguishing proper edge-coloring is the minimum number of colors required for the proper edge-coloring of [Formula: see text] in which no two adjacent vertices are incident to edges colored with the same set of colors.

Life cycle analysis of road construction and use [PDF]

open access: yes, 2019
Both the construction and use of roads have a range of environmental impacts; therefore, it is important to assess the sources of their burdens to adopt correct mitigation policies.

Sufficient Conditions of 6-Cycles Make Planar Graphs DP-4-Colorable

open access: yesMathematics, 2022
In simple graphs, DP-coloring is a generalization of list coloring and thus many results of DP-coloring generalize those of list coloring. Xu and Wu proved that every planar graph without 5-cycles adjacent simultaneously to 3-cycles and 4-cycles is 4 ...

OPERATING ELEMENTS DAMAGE OF TOOLS CONNECTED WITH THE PLASTIC DEFORMATION OF HARDENED ORGANIC COMPOUNDS

open access: yesNauka ta progres transportu, 2014
Purpose. Most of the freight traffic in Ukraine is made by railway transport. Government statistics of annual railway freight traffic (January-November) records the following data: 2011 - 468 million tons (108.2% to 2010); 2012 – 421.5 million tons (98.
