Performance analysis of an M/G/1 retrial G-queue with feedback under working breakdown services [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2020
In this paper, we investigate a new type of retrial queueing model with feedback and working breakdown services. The regular busy server may become defective by disasters (negative customers) at any point of time.

ON HOP DOMINATION NUMBER OF SOME GENERALIZED GRAPH STRUCTURES

open access: yesUral Mathematical Journal, 2021
A subset \( H \subseteq V (G) \) of a graph \(G\) is a hop dominating set (HDS) if for every \({v\in (V\setminus H)}\) there is at least one vertex  \(u\in H\) such that \(d(u,v)=2\).

Count Me In: Exploring Equity, Diversity, and Inclusion through Mathematics and Children's Literature

open access: yesThe Reading Teacher, Volume 77, Issue 2, Page 189-198, September/October 2023., 2023
Abstract This article explores the potential of using children's literature in elementary mathematics classrooms as contexts for students to understand more fully the issues of equity, diversity, and inclusion. Informed by culturally responsive pedagogy, opportunities to link children's literature to mathematics education create cultural relevance for ...

QSPR Study and Distance‐Based New Topological Descriptors of Some Drugs Used in the COVID‐19 Treatment

open access: yesJournal of Mathematics, Volume 2023, Issue 1, 2023., 2023
In chemistry and medical sciences, it is essential to study the chemical, biological, clinical, and therapeutic aspects of pharmaceuticals. To save time and money, mathematical chemistry focuses on topological indices used in quantitative structure‐property relationship (QSPR) models to predict the properties of chemical structures.

Reliability and Optimization Measures of Retrial Queue with Different Classes of Customers under a Working Vacation Schedule

open access: yesDiscrete Dynamics in Nature and Society, Volume 2022, Issue 1, 2022., 2022
A working vacation queueing model is described in this work, with three different classes of customers: regular, priority, and disaster. The regular server serves all arriving customers, whereas the optional reservice is only provided to those who request it. The Bernoulli working vacation (BWV) schedule is considered.

[Retracted] Effect of Grey and White Portland Cement Fillers on Flexural and Shear Strength of GFRP Composite Material

open access: yesAdvances in Materials Science and Engineering, Volume 2021, Issue 1, 2021., 2021
The mechanical behaviour of glass fiber reinforced polymer (GFRP) composite depends on the type of matrix, filler, and fiber architecture. In order to develop high‐strength polymer matrix composites, the composites containing 5%, 10%, and 15% each of Portland grey and white cement filler are prepared by uniformly mixing the epoxy and filler materials ...

A Review of Traditional and Data-Driven Approaches for Disruption Prediction in Different Tokamaks [PDF]

open access: yesE3S Web of Conferences
Tokamak is a nuclear fusion reactor; inside, the two lighter nuclei known as deuterium and tritium are first ionized together to form plasma, which is heated up to 150 million degrees Celsius, and then they are confined by the torus-shaped magnetic field.
