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 ...

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 ...

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.

Services within a busy period of an M/M/1 queue and Dyck paths [PDF]
, 2005 We analyze the service times of customers in a stable M/M/1 queue in equilibrium depending on their position in a busy period. We give the law of the service of a customer at the beginning, at the end, or in the middle of the busy period. It enables as a

Fluid queues driven by a birth and death process with alternating flow rates
Mathematical Problems in Engineering, Volume 2004, Issue 5, Page 469-489, 2004., 2004 Fluid queue driven by a birth and death process (BDP) with only one negative effective input rate has been considered in the literature. As an alternative, here we consider a fluid queue in which the input is characterized by a BDP with alternating positive and negative flow rates on a finite state space. Also, the BDP has two alternating arrival rates

Asymptotic analysis by the saddle point method of the Anick‐Mitra‐Sondhi model
International Journal of Stochastic Analysis, Volume 2004, Issue 1, Page 19-71, 2004., 2004 We consider a fluid queue where the input process consists of N identical sources that turn on and off at exponential waiting times. The server works at the constant rate c and an on source generates fluid at unit rate. This model was first formulated and analyzed by Anick et al. (1982).

A finite capacity bulk service queue with single vacation and Markovian arrival process
International Journal of Stochastic Analysis, Volume 2004, Issue 4, Page 337-357, 2004., 2004 Vacation time queues with Markovian arrival process (MAP) are mainly useful in modeling and performance analysis of telecommunication networks based on asynchronous transfer mode (ATM) environment. This paper analyzes a single‐server finite capacity queue wherein service is performed in batches of maximum size “b” with a minimum threshold “a” and ...

Fluid queues driven by a discouraged arrivals queue
International Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 24, Page 1509-1528, 2003., 2003 We consider a fluid queue driven by a discouraged arrivals queue and obtain explicit expressions for the stationary distribution function of the buffer content in terms of confluent hypergeometric functions. We compare it with a fluid queue driven by an infinite server queue.

Optimal control of a large dam [PDF]
, 2006 A large dam model is an object of study of this paper. The parameters $L^{lower}$ and $L^{upper}$ are its lower and upper levels, $L=L^{upper}-L^{lower}$ is large, and if a current level of water is between these bounds, then the dam is assumed to be in ...

Stein's Method for the Single Server Queue in Heavy Traffic [PDF]
, 2019 Following recent developments in the application of Stein's method in queueing theory, this paper is intended to be a short treatment showing how Stein's method can be developed and applied to the single server queue in heavy traffic. Here we provide two
