Performance Analysis of an IoT Service Platform with Retrial Requests, Working Vacations, Balking and Feedback

open access: yesMathematics
The increasing deployment of Internet of Things (IoT) service platforms has motivated the development of queueing models capable of capturing congestion, retrials, and service interruptions. This paper investigates an M/M/1 retrial queue with balking and

‘Do You Realise People Are Dying There?!’: Ukrainian Adolescents Reflecting on Death During Wartime

open access: yesChildren &Society, EarlyView.
ABSTRACT This article explores how Ukrainian refugee adolescents in Romania think and speak about death and loss amid war and displacement. While contemporary Western societies display an unprecedented visibility of death, they continue to exclude children from genuine conversations about mortality, maintaining a protective silence.

A transient solution to the M/M/c queuing model equation with balking and catastrophes

open access: yesCroatian Operational Research Review, 2017
In this paper, we consider a Markovian multi-server queuing system with balking and catastrophes. The probability generating function technique along with the Bessel function properites is used to obtain a transient solution to the queuing model.

Budding speciation, mitochondrial capture and introgression between surface and cave lineages in the Asellus aquaticus species complex

open access: yesCladistics, EarlyView.
Abstract Replicated pairs of ancestral and evolutionarily derived populations provide opportunities to test hypotheses about the deterministic laws of evolution. The Asellus aquaticus species complex is an invertebrate model system with several independent surface‐to‐cave transitions and a complicated and unresolved evolutionary history.

Coordination and Decision of Supply Chain Under: Price-Dependent Demand and Customer Balking Behavior

open access: yes, 2019
In order to investigate supply chain coordination and decision under customer balking and stochastic demand, the article considers a two-echelon supply chain consisting of one manufacturer with risk-neutral and one retailer with risk-neutral and develops

Cost Optimization and Sensitivity Analysis of the Machine Repair Problem with Variable Servers and Balking [PDF]

open access: yes, 2011
We consider a machine repair model with M identical machines and variable servers considering balking concept. A recursive method is applied o develop analytical steady-state solutions.

“Not Lower Class, Lazy Class”: Food Loathing as Class Abjection and Distinction via Instagram Comments on Mama J. Rae's Lunchbox‐Packing Video

open access: yesJournal of Sociolinguistics, EarlyView.
ABSTRACT This article examines 4206 Instagram comments on a lunchbox‐packing video posted by Mama J. Rae, who self‐identifies as a “lower middle class wife.” Her excessive use of processed foods and sugary beverages provokes negative responses, many of which explicitly connect her lunchbox‐packing practices to class identity.

An interarrival hyperexponential machine interference with balking, reneging, state-dependent, spares, and an additional server for longer queues

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
The aim of this paper is to treat the analytical solution of the truncated interarrival hyperexponential machine interference queue: H2/M/1/m+Y/m+Y in case of two branches with the following concepts: balking, reneging, state-dependent, spares, and an ...

Towards a Responsible Liberalism

open access: yesKyklos, EarlyView.
ABSTRACT Liberalism has many faces, ranging from that which emphasises the laissez‐faire approach of freedom from interference to the interventionist perspective on providing the conditions for people to exercise their liberty. In this essay, after summarising the arguments made by four prominent liberal scholars (namely, Keynes, Hayek, Buchanan and ...

Equilibrium Joining Strategies of Delay-Sensitive Customers in a Queueing System with Service Quality Feedback

open access: yesDiscrete Dynamics in Nature and Society, 2020
In some queueing systems, customers are frequently asked for giving a service quality feedback for their service at their service completion instants. Based on this phenomenon, in this paper, we model this type of queueing systems as clearing queues with
