DOI: 10.1007/s10476-020-0038-6
Abstract: The well-known stationary phase formula gives us a way to find asymptotics of oscillating integrals so long as the symbol is regular enough (in comparison to the large parameter controlling the oscillation). However in a… read more here.

DOI: 10.1007/s10479-017-2617-x
Abstract: This paper presents an extension of our earlier paper on the 1-out-of-N repairable cold standby system (i.e., Barron IIE Trans 47:1139–1151, 2015). Specifically, we consider an R-out-of-N repairable system where the lifetimes of the units… read more here.

Heavy-tailed phase-type distributions: a unified approach
Sign Up to like & getrecommendations! Published in 2022 at "Extremes"
DOI: 10.1007/s10687-022-00436-8
Abstract: A phase-type distribution is the distribution of the time until absorption in a finite state-space time-homogeneous Markov jump process, with one absorbing state and the rest being transient. These distributions are mathematically tractable and conceptually… read more here.

DOI: 10.1007/s11009-021-09875-5
Abstract: In this paper, we are interested in the dependence between lifetimes based on a joint survival model. This model is built using the bivariate Sarmanov distribution with Phase-Type marginal distributions. Capitalizing on these two classes… read more here.

DOI: 10.1016/j.bsecv.2021.04.004
Abstract: Abstract Economical alumina precursors, derived from bauxite or nepheline ores, were calcined through a very short time process. Results showed that phases of the precursor are a key parameter on the flash calcination process. The… read more here.

DOI: 10.1017/apr.2024.67
Abstract: This paper characterizes irreducible phase-type representations for exponential distributions. Bean and Green (2000) gave a set of necessary and sufficient conditions for a phase-type distribution with an irreducible generator matrix to be exponential. We extend… read more here.
