The Generalized Inflection S-Shaped Software Reliability Growth Model

In this paper, the new generalized inflection S-shaped software reliability growth model is proposed. It is a very flexible finite failure Poisson process that possesses two distinguishing features: 1) includes as special cases the popular inflection S-shaped model, Goel generalized nonhomogenous...

A new class of multivariate counting processes and its characterization

In this paper, we suggest a new class of multivariate counting processes which generalizes and extends the multivariate generalized Polya process recently studied in Cha and Giorgio [On a class of multivariate counting processes, Adv. Appl. Probab. 48 (2016), pp. 443–462]. Initially, we...

The peak over the design threshold in strong earthquakes

In state-of-the-art seismic design, reference seismic actions are based on probabilistic seismic hazard assessment, which provides the ground-motion intensity corresponding to a reference return period of exceedance at the site. Exceedance of elastic actions, which is systematically observed in the&#x...

Aftershocks’ effect on structural design actions in Italy

Although earthquakes generally form clusters in both space and time, only mainshocks, usually the largest magnitude events within clusters, are considered by probabilistic seismic hazard analysis (PSHA; Cornell, 1968). On the other hand, aftershock PSHA (APSHA), based on the modified Omori l...

A perturbed gamma degradation process with degradation dependent non-Gaussian measurement errors

This paper proposes and illustrates a new perturbed gamma degradation process where the measurement error is modeled as a non-Gaussian random variable that depends stochastically on the actual degradation level. The expression of the likelihood function for a generic set of noisy degrad...
