Stationary Phase Type Estimates for Low Symbol Regularity
Sign Up to like & getrecommendations! Published in 2019 at "Analysis Mathematica"
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.

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: 10.1016/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: 10.1109/access.2020.3018821
Abstract: The traditional shock model generally describes the magnitude of the cumulative damage caused by a random shock sequence and compares the magnitude with a predetermined threshold to obtain the failure time of a component. There… read more here.
