In the chapter, statistical methods for estimating the parameters of degradation processes for different data structures are developed and compared. 展开 关键词: Degradation processdegradation process failure timefailure time likelihood functionlikelihood function maximum likelihood estimationmaximum likelihood ...
it was assumed that the degradation of each PC over time was governed by a Wiener degradation process and the dependency between them was characterized by the Frank copula function.A bivariate Wiener process model with measurement errors was used to model the degradation measurements.A two-stage me...
Recently, (KHP93, due to light intensity fluctuations and threshold- KHP94, BaiSO), document degradation models were ing level, and (ii) the blurring that occurs due to proposed that model the local distortion introduced the point-spread function of the optical system the during the printing ...
"The impact of estimating the range of an extended target with a point target model is analysed, showing that a model mismatch leads to severe performance degradation in the near-field region." "Expressions emphasising the parameters’ impact are obtained,the parametersbeing the carrier frequency, ...
Under a mild assumption, an analytical approximation to the probability density function of the RL is derived in a closed-form, which becomes quite useful in maintenance decision making. The unknown parameters of the model that characterize the population-based degradation characteristics are obtained ...
PROBLEM TO BE SOLVED: To provide a convenience method to estimate capacity of a Li ion cell, a convenient apparatus to judge deterioration of an Li ion cell and an Li ion cell pack equipped with a function of estimating the capacity of the cell. SOLUTION: The method of estimating the capa...
Estimating Battery Degradation The battery degradation is modeled by decreasing capacity . In this example, the battery capacity is set to decrease 1 Ah per discharge-charge cycle to illustrate the effect of degradation. Since the degradation rate of capacity is not known in advance, set the state...
An alternative degradation reliability modeling approach is presented in this paper. This approach extends the graphical approach used by several authors by considering the natural ordering of performance degradation data using a truncated Weibull distribution. Maximum Likelihood Estimation is used to provide...
