On the Maintenance Modeling of a Hybrid Model with Exponential Repair Efficiency [PDF]
International Journal of Mathematical, Engineering and Management Sciences, 2021 In the reliability literature, maintenance efficiency is usually dealt with as a fixed value. Since repairable systems are subject to different degrees and types of repair, it is more convenient to regard a random variable for maintenance efficiency ...

On the Rate of Crustal Failures in Young Magnetars [PDF]
The Astrophysical Journal Letters, 2020 Abstract The activity of magnetars is powered by their intense and dynamic magnetic fields and has been proposed as the trigger to extragalactic fast radio bursts. Here we estimate the frequency of crustal failures in young magnetars, by computing the magnetic stresses in detailed magnetothermal simulations including Hall drift and ohmic
