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.

Stochastic study of a retrial queue with impatience under a multi-level environment incorporating sensor-enabled shock detection

Scientific African
This study analyzes an M/M/1 retrial queue with impatient customers under a multi-level stochastic environment, utilizing a sensor as a notification mechanism for detecting random shocks.

Operational behavior of the MAP/G/1 queue under N‐policy with a single vacation and set‐up

International Journal of Stochastic Analysis, Volume 15, Issue 2, Page 151-180, 2002., 2002
This paper considers the MAP/G/1 queue under N‐policy with a single vacation and set‐up. We derive the vector generating functions of the queue length at an arbitrary time and at departures in decomposed forms. We also derive the Laplace‐Stieltjes transform of the waiting time. Computation algorithms for mean performance measures are provided.

On functionals of a marked Poisson process observed by a renewal process

International Journal of Mathematics and Mathematical Sciences, Volume 26, Issue 7, Page 427-436, 2001., 2001
We study the functionals of a Poisson marked process Π observed by a renewal process. A sequence of observations continues until Π crosses some fixed level at one of the observation epochs (the first passage time). In various stochastic models applications (such as queueing with N‐policy combined with multiple vacations), it is necessary to operate ...

Chemical Stability of Ceftazidime Compounded in Saline, Glycerin and Dexamethasone‐SP Solutions Stored at −20°C, 4°C and 25°C Over a 60 Day Period

Veterinary Dermatology, Volume 36, Issue 6, Page 862-869, December 2025.
ABSTRACT Background Chronic cases of canine otitis externa (OE) often develop infections with Pseudomonas aeruginosa (PA). Given the organism's high level of resistance, veterinary surgeons often turn to compounded solutions. Limited data describing the stability and potency of compounded ceftazidime (CAZ) solutions are available, which may affect ...

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

International Journal of Mathematics and Mathematical Sciences, Volume 27, Issue 12, Page 737-747, 2001., 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 additional server for longer queues.
