Purpose – This study aims to focus on asset management of large-scale information systems supporting infrastructures and especially seeks to address a methodology of their statistical deterioration prediction based on their historical inspection data. Information systems are composed of many devices. Deterioration process i.e. wear-out failure generation process of those devices is formulated b...

Interval-censored data consist of adjacent inspection times that surround an unknown failure time. We have in this paper reviewed the classical approach which is maximum likelihood in estimating the Weibull parameters with interval-censored data. We have also considered the Bayesian approach in estimating the Weibull parameters with interval-censored data under three loss functions. This study ...

To understand how organisms adapt, researchers must link performance and microhabitat. However, measuring performance, especially maximum performance, can sometimes be difficult. Here, we describe an improvement over previous techniques that only consider the largest observed values as maxima. Instead, we model expected performance observations via the Weibull distribution, a statistical approa...

In this paper we examine the effects of spatial fading correlation on bit-error probability (BEP) and channel capacity of orthogonal space–time block codes (STBCs) over multiple-input multiple-output (MIMO) Weibull fading channel. We derive the characteristic function (cf) of the signal-to-noise ratio (SNR) which is linear combination of Laplace transforms weighted by the eigenvalues of the cha...
