International Journal of Mathematics and Mathematical Sciences, 1992 The authors study the queueing process in a single-server queueing system with state dependent service and with the input modulated by a semi-Markov process embedded in the queueing process. It is also assumed that the server capacity is r≥1 and that any

Reliability measures of a computer system with priority to PM over the H/W repair activities subject to MOT and MRT [PDF]
Management Science Letters, 2015 This paper concentrates on the evaluation of reliability measures of a computer system of two-identical units having independent failure of h/w and s/w components. Initially one unit is operative and the other is kept as spare in cold standby. There is a

International Journal of Mathematics and Mathematical Sciences, 1992 This paper introduces a bulk queueing system with a single server processing groups of customers of a variable size. If upon completion of service the queueing level is at least r the server takes a batch of size r and processes it a random time ...

Fast modeling of regenerative amplifier free-electron lasers
Physical Review Research, 2023 High-gain free-electron lasers (FELs) are becoming important light sources at short wavelengths such as the EUV and x-ray regimes. A particularly promising concept is the regenerative amplifier FEL (RAFEL), which can greatly increase the brightness and ...

On functionals of a marked Poisson process observed by a renewal process
International Journal of Mathematics and Mathematical Sciences, 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).

Modelling the effectiveness of land‐based natural flood management in a large, permeable catchment
Journal of Flood Risk Management, 2023 In the United Kingdom, woodland planting and soil and crop management are being promoted as approaches to tackling flooding. Although evidence is limited, it is thought tree planting and regenerative agriculture practices such as crop–herbal ley pasture ...

Early redox activities modulate Xenopus tail regeneration. [PDF]
, 2018 Redox state sustained by reactive oxygen species (ROS) is crucial for regeneration; however, the interplay between oxygen (O2), ROS and hypoxia-inducible factors (HIF) remains elusive.
