Isoscalar Giant Octupole Resonance ISGOR of 116Cd using Self-Consistent Skyrme QRPA
East European Journal of Physics, 2023 Collective models based on the random phase approximation (RPA) are widely used to accurately depict collective modes of response. They can quickly calculate the strength function for the entire nuclear mass range.

On the Relation between Phase-Type Distributions and Positive Systems
Abstract and Applied Analysis, 2015 The relation between phase-type representation and positive system realization in both the discrete and continuous time is discussed. Using the Perron-Frobenius theorem of nonnegative matrix theory, a transformation from positive realization to phase ...

The Application of Phase Type Distributions for Modelling Queuing Systems [PDF]
Journal of Systemics, Cybernetics and Informatics, 2007 Queuing models are important tools for studying the performance of complex systems, but despite the substantial queuing theory literature, it is often necessary to use approximations in the case the system is nonmarkovian.

On Hitting Times for Markov Time Series of Counts with Applications to Quality Control
Revstat Statistical Journal, 2016 Examples of time series of counts arise in several areas, for instance in epidemiology, industry, insurance and network analysis. Several time series models for these counts have been proposed and some are based on the binomial thinning operation ...

Equilibrium distributions of discrete phase type [PDF]
, 2013 It is well known that the family of discrete phase-type distributions is closed under convolutions, mixtures, and the unary “geometric mixture” operation. In this article, we show that the equilibrium distributions of this family are again of phase type.

On the Representation of Correlated Exponential Distributions by Phase Type Distributions
ACM SIGMETRICS Performance Evaluation Review, 2022 In this paper we present results for bivariate exponential distributions which are represented by phase type distributions. The paper extends results from previous publications [3, 11] on this topic by introducing new representations that require a smaller number of phases to reach some correlation coefficient and introduces different ways to describe ...
