Wear and fatigue of wheels have a great effect on the maintenance of railway vehicles and running safety.In the case Dishwasher Heating Element of an urban railway where no rail lubrication system is installed, it is reported that the risk of wheel damage is high in curved sections.In the present study, we intended to present a method of designing
Abstract Background Large-scale climatic variability has been implicated in the population dynamics of many vertebrates throughout the Northern Hemisphere, but has not been demonstrated to directly influence dynamics at multiple trophic levels of any single system.Using Dishwasher Heating Element data from Isle Royale, USA, comprising time series o
In order to identify various kinds of combined power quality disturbances, the singular value decomposition (SVD) and the improved total least squares-estimation of signal parameters via rotational invariance techniques (TLS-ESPRIT) are combined as the basis of disturbance identification in this paper.SVD is applied to identify the catastrophe poin
Partial discharge (PD) that occurs due to insulation breakdown is a precursor to plant failure.PD emits electromagnetic pulses which radiate through space and can be detected using appropriate sensing devices.This paper proposed an enhanced radiolocation technique to locate PD.This approach depends on sensing the radio frequency spectrum and the ex
We consider a time-non-homogeneous double-ended queue subject to catastrophes and repairs.The catastrophes occur according to a non-homogeneous Poisson process and lead the system into a state of failure.Instantaneously, the system is put under repair, such that repair time is governed by a time-varying intensity function.We analyze the transient C
