Veterinary Dermatology, Volume 34, Issue 6, Page 543-553, December 2023., 2023 Background – Hymenoptera envenomation with honey bee (Apis mellifera) and paper wasp (Polistes spp.) may cause life‐threatening anaphylaxis in dogs. In human patients, clinical history, intradermal testing (IDT) and measurement of allergen‐specific serological immunoglobulin (Ig)E (sIgE) are used to support a diagnosis of Hymenoptera venom ...

A transient analysis to the M(τ)/M(τ)/k queue with time-dependent parameters
Open Mathematics, 2021 This work considers the infinite multi-server Markovian queueing model with balking and catastrophes where the rates of arrivals, service, balking, and catastrophes are time dependent. The catastrophes arrive as negative customers to the system.

Performance and sensitivity analysis of an M/G/1 queue with retrial customers due to server vacation
Ain Shams Engineering Journal, 2020 This paper treats an M/G/1 queue with retrial customers due to server vacation, which can be used to model a hospital service system. When an arriving customer finds the server on vacation at his arrival epoch, he either enters the retrial group with ...

The number of overtakes in an M/M/2 queue
Operations Research Perspectives, 2018 The phenomenon of overtaking in queueing systems and queueing networks has been addressed by several authors with various motivations in the last decades. Nevertheless, up to now, for the relatively simple M/M/2/FCFS queue, the distribution of the number

Functional analysis method for the M/G/1 queueing model with single working vacation
Open Mathematics, 2018 In this paper, we study the asymptotic property of underlying operator corresponding to the M/G/1 queueing model with single working vacation, where both service times in a regular busy period and in a working vacation period are function. We obtain that

The expected discrimination frequency for two-server queues
Operations Research Perspectives, 2018 Fairness measures for queues were introduced for measuring the individual satisfaction of human customers with respect to the waiting experience. The measure which performs best in some sense is the expected discrimination frequency (DF).

Behaviour of passage time for a queueing network model with feedback: a simulation study
International Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 24, Page 1267-1278, 2004., 2004 The study of the queueing system presented in this note was motivated by its possible application to a multiprogramming computer system. The paper considers a closed network with two service centres with feedback. The steady‐state behaviour of the passage time, the random times for a job to traverse a portion of the network, is examined through ...

Applications of Stochastic Semigroups to Queueing Models
Annales Mathematicae Silesianae, 2019 Non-markovian queueing systems can be extended to piecewise-deterministic Markov processes by appending supplementary variables to the system. Then their analysis leads to an infinite system of partial differential equations with an infinite number of ...

Reservicing some customers in M/G/1 queues under three disciplines
International Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 32, Page 1715-1723, 2004., 2004 Consider an M/G/1 production line in which a production item is failed with some probability and is then repaired. We consider three repair disciplines depending on whether the failed item is repaired immediately or first stockpiled and repaired after all customers in the main queue are served or the stockpile reaches a specified threshold.
