Quasi-Birth-and-Death Processes with Rational Arrival Process Components [PDF]

, 2007
In this paper we introduce the concept of a Quasi-Birth-and-Death process (QBD) with Rational Arrival Process components. We use the physical interpretation of a Rational Arrival Process (RAP), developed by Asmussen and Bladt, to consider such a Markov ...

Dynamics and Structure of Molten Neodymium Titanate

Journal of the American Ceramic Society, Volume 109, Issue 6, June 2026.
ABSTRACT Binary rare earth titanates can be vitrified using levitation melt quenching, and their glasses are promising for optical applications. To better understand their thermophysical properties and dynamics, we have used molecular dynamics (MD) and empirical potential structure refinement (EPSR) to simulate molten neodymium titanate, 83TiO2–17Nd2O3.

Using Stochastic Simulations to Shed Light on How to Deploy Speed Breeding and Genomic Selection in Self‐Pollinated Recurrent Breeding Programs

Plant Breeding, Volume 145, Issue 3, Page 625-636, June 2026.
ABSTRACT Speed breeding can shorten breeding cycles and, when combined with genomic selection, can accelerate genetic gain. Yet it remains unclear how different integration strategies affect long‐term response, genetic variance and cost‐efficiency in small public programs.

Performance Forecasting for Multi-Server Retrial Queue with Possibility of Processing Repetition and Server Reservation for Repeating Users

Stats
This study focuses on forecasting and optimizing the performance of a real-world object modelled by a multi-server queueing system that processes two types of users: primary (new) users and repeating users.

ANFIS computing for $MAP/PH/1$ queueing system with server deterioration and recovery under vacation and backup server

Mathematics in Applied Sciences and Engineering
We examine a queueing system with vacation in which the service rate deteriorates during the service and recovers the service rate during the vacation. The backup server with less service rate takes the place of the main server during the recovery time.

Departure processes from MAP/PH/1 queues

, 1999
A MAP/PH/1 queue is a queue having a Markov arrival process (MAP), and a single server with phase-type (PH -type) distributed service time. This thesis considers the departure process from these type of queues.
