A Simple Repairable System with Warning Device

Journal of Function Spaces, 2015
This paper considers a simple repairable system with a warning device which can signal an alarm when the system is not in good condition and a repairman who can have delayed-multiple vacations.

A MAP-modulated fluid flow model with multiple vacations

, 2012
We consider a MAP-modulated fluid flow queueing model with multiple vacations. As soon as the fluid level reaches zero, the server leaves for repeated vacations of random length V until the server finds any fluid in the system. During the vacation period,

Tri‐Functional Electrocatalysis for Zinc–Air Battery Coupled Water Splitting: A Catalyst‐Electrode‐Device‐System Perspective

Advanced Science, EarlyView.
This review establishes a catalyst–electrode–device–system framework for tri‐functional HER/OER/ORR electrocatalysis that couples water splitting with Zn–air batteries. Five catalyst families are covered: noble‐metal, metal‐based, single‐atom, heterostructure, and metal‐free systems.

Stability Analysis of a Repairable System with Warning Device and Repairman Vacation

Journal of Function Spaces and Applications, 2013
This paper considers a simple repairable system with a warning device and a repairman who can have delayed-multiple vacations. By Markov renewal process theory and the probability analysis method, the system is first transformed into a group of ...

Predicting the Reactivity of Acyclic Silylenes and Germylenes in Hydrogen Activation Using Machine Learning

Advanced Science, EarlyView.
Statistical models for the prediction of the energy profile of H2 activation by silylenes and germylenes were developed. A simple model based on increments of the elements in α‐position enabled robust energy prediction, extrapolation to new structures, and transferability to new tetrylenes and substrates.

Reliability Analysis of a Limited-Capacity Dual-Repair System with Hybrid Vacation Policies [PDF]

International Journal of Mathematical, Engineering and Management Sciences
This study investigates the reliability of a machine dual-repair system (MDRS) with limited capacity and multiple operational vacations (OV). Multiple operational vacation is a mechanism that involves the process of the two types of vacation, one as ...

A HEURISTIC ALGORITHM FOR THE OPTIMIZATION OF M/M/s QUEUE WITH MULTIPLE WORKING VACATIONS [PDF]

, 2012
[[abstract]]This paper focuses on an M/M/s queue with multiple working vacations such that the server works with different service rates rather than no service during the vacation period.

Experience of Identity Change in People Who Reported a Diagnosis of Multiple Sclerosis : A Qualitative Inquiry [PDF]

, 2019
Background: A diagnosis of multiple sclerosis (MS) can lead to changes to a person’s sense of self. The aim of this study was to investigate the subjective experience of identity change and subsequent adjustment to MS.
