The Compound Class of Linear Failure Rate-Power Series Distributions: Model, Properties and Applications [PDF]

open access: yesarXiv, 2014
We introduce in this paper a new class of distributions which generalizes the linear failure rate (LFR) distribution and is obtained by compounding the LFR distribution and power series (PS) class of distributions. This new class of distributions is called the linear failure rate-power series (LFRPS) distributions and contains some new distributions ...

On the Maintenance Modeling of a Hybrid Model with Exponential Repair Efficiency [PDF]

open access: yesInternational 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 ...

Developing a Model of Estimating the Failure Rate for Main Urban Water Pipes Using Gene Expression Programming [PDF]

open access: yesعلوم و مهندسی آب و فاضلاب, 2022
One of the major problems with urban water supply networks is the large volume of water wastage due to various incidents that cause damage. These damages are mainly irreversible and costly; thus, it is increasingly important to understand the causes of ...

Does the Tax Cuts Policy Lower Firm Survival Risk? Evidence from China [PDF]

open access: yesE3S Web of Conferences, 2023
This paper examines the effect of tax cuts policy on firm survival risk. We analyze a panel data of China’s listed companies over the period 20082021 based on two different techniques: Kaplan-Meier survival estimator and the Cox proportional hazards ...

Using Online Customer Reviews to Classify, Predict, and Learn about Domestic Robot Failures [PDF]

open access: yesHonig, S., Bartal, A., Parmet, Y. et al. Using Online Customer Reviews to Classify, Predict, and Learn About Domestic Robot Failures. Int J of Soc Robotics (2022). https://doi.org/10.1007/s12369-022-00929-3, 2022
There is a knowledge gap regarding which types of failures robots undergo in domestic settings and how these failures influence customer experience. We classified 10,072 customer reviews of small utilitarian domestic robots on Amazon by the robotic failures described in them, grouping failures into twelve types and three categories (Technical ...

On the Rate of Crustal Failures in Young Magnetars [PDF]

open access: yesThe 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
