In this paper, we propose modeling for a single repairable system with a hierarchical structure under the assumption that the failures follow a nonhomogeneous Poisson process (which corresponds to minimal repair action) with a power-law intensity fun

One of the current challenges in two-phase flow is the characterization of phase inversion in the oil and gas industry. Empirical and semi-empirical models have been developed by several researchers, allowing limited predictions through correlations.
