Modeling Leukemia in Children Using Phase-type Distribution [PDF]

open access: yesJournal of Kerman University of Medical Sciences, 2017
Background: In this study, with the aim of modeling Leukemia in children using Phase-type distribution, three transitional phases including diagnosis, brain metastasis and testis/ovary metastasis, and one absorotion phase of recovery/death have been ...

Definition of Type of Single-Phase Fault in Overhead Power Distribution Networks with Isolated Neutral

open access: yesИзвестия высших учебных заведений и энергетических объединенний СНГ: Энергетика, 2012
The paper considers the distinctive features of different types of single-phase damage in the distribution networks. By results of researches the algorithm is developed for definition of type of single-phase damage on the basis of the information on ...

PhaseTypeR: an R package for phase-type distributions in population genetics

open access: yesJournal of Open Source Software, 2023
Phase-type distributions have traditionally been used in actuarial sciences and queuing theory, and, more recently, in population genetics. In order to facilitate the use of phase-type theory in population genetics, we present PhaseTypeR, a general ...

Building mean field ODE models using the generalized linear chain trick & Markov chain theory

open access: yesJournal of Biological Dynamics, 2021
The well known linear chain trick (LCT) allows modellers to derive mean field ODEs that assume gamma (Erlang) distributed passage times, by transitioning individuals sequentially through a chain of sub-states.

On Queues with Working Vacation and Interdependence in Arrival and Service Processes

open access: yesMathematics, 2023
In this paper, we consider two queuing models. Model 1 considers a single-server working vacation queuing system with interdependent arrival and service processes.

Development of drift-flux correlations for vertical forward bubble column-type gas-liquid lead-bismuth two-phase flow

open access: yesFrontiers in Energy Research, 2022
Bubble columns represent an extreme case of gas-liquid two-phase flow, where net liquid velocity is zero and the gas simply bubbles up through the liquid.

On the canonical representation of phase type distributions [PDF]

open access: yesPerformance Evaluation, 2009
The characterization and the canonical representation of order-n phase type distributions (PH(n)) is an open research problem. This problem is solved for n=2, since the equivalence of the acyclic and the general PH distributions has been proven for a long time.

Multi-server queueing system with reserve servers

open access: yesЖурнал Белорусского государственного университета: Математика, информатика, 2019
In this paper, we investigate a multi-server queueing system with an unlimited buffer, which can be used in the design of energy consumption schemes and as a mathematical model of unreliable real stochastic systems.

On the nature of Phase-type Poisson distributions [PDF]

open access: yesAnnals of Actuarial Science, 2013
AbstractMatrix-form Poisson probability distributions were recently introduced as one matrix generalization of Panjer distributions. We show in this paper that under the constraint that their representation is to be nonnegative, they have a physical interpretation as extensions of PH distributions, and we name this restricted familyPhase-type Poisson ...
