CFAR Detection of Extended Targets in SAR Images based on goodness-of-fit test

7th European Conference on Synthetic Aperture Radar, 2008

A novel CFAR scheme based on goodness-of-fit (GoF) test is proposed in this paper. This scheme begins with a logarithmic amplifier, which transforms the clutter PDF, whether Weibull or Lognormal into a location-scale one, some relevant properties of which are exploited to ensure CFAR. A Goodness-of-fit test is adopted at last to decide whether the samples from target window belong ...


The failure of MTTF in availability evaluation

Annual Reliability and Maintainability Symposium. 2002 Proceedings (Cat. No.02CH37318), 2002

In this paper, a truncated bathtub is proposed to model the failure rate of a product with perfect burn-in. We expose some counter-intuition observations, e.g., increasing the MTTF does not necessarily increase the average and instantaneous availability during the product's lifetime, and the average and instantaneous availability could be improved without changing the MTTF. The MTTF and the steady-state availability ...


Analysis of failure prediction methods

2017 6th International Youth Conference on Energy (IYCE), 2017

This paper describes the effects of constant and varied maintenance strategies through an example of artificially generated failure data. During the constant maintenance strategy two main cases are distinguished. In the first example constant number of failures while in the second example specified percentage of failures are prevented with maintenance every year. Through the case study of the varied maintenance ...

Selection of Weibull Shape Parameter, Based on Adaptive Estimation

IEEE Transactions on Reliability, 1983

The paper provides a modified likelihood ratio criterion for deciding whether or not the Weibull shape parameter is unity. The analysis is based on a Monte Carlo study of 1000 samples of simulated life-test data. The method has been used as a preliminary test for estimating unknown parameters. Thus two sets of adaptive estimators of the scale and the shape ...

We expose some counter-intuition observations, e.g., increasing the MTTF does not necessarily increase the average and instantaneous availability during the product's lifetime, and the average and instantaneous availability could be improved without changing the MTTF. The MTTF and the steady-state availability are not particularly informative and fail to evaluate the product with time-varying failure rate and short upgrading interval.

  • Analysis of failure prediction methods

    This paper describes the effects of constant and varied maintenance strategies through an example of artificially generated failure data. During the constant maintenance strategy two main cases are distinguished. In the first example constant number of failures while in the second example specified percentage of failures are prevented with maintenance every year. Through the case study of the varied maintenance strategy growing and decreasing maintenance methods are examined. Thereafter the CROW-AMSAA model is presented through an illustrative example, and compared with the most popular Weibull distribution method as for the advantages and disadvantages of each technique. In the final section of the paper a set of equipment, where there is a high percentage of intact items in the system, is examined with the help of right censoring.

The analysis is based on a Monte Carlo study of 1000 samples of simulated life-test data. The method has been used as a preliminary test for estimating unknown parameters. Thus two sets of adaptive estimators of the scale and the shape parameters are proposed and their s-efficiency studied by a Monte Carlo simulation. The adaptive estimators are better.

  • A new on-state drain-bias TDDB lifetime model and HCI effect on drain-bias TDDB of ultra thin oxide

    For the first time, a new drain-bias T<sub>BD</sub> lifetime model is proposed to precisely predict at various Vd, Vg and channel length for ultra thin oxide. The TBD lifetime with drain-bias can be decoupled to small voltage drop at drain-side increased TBD lifetime and hot carrier effect (HCI) degraded the TBD lifetime. The mechanism of oxide breakdown with drain-bias is also well understood as oxide traps distributed from the source side to the center of channel induce the oxide breakdown.

  • Probability distribution of HVDC capacity considering repairable and aging failures

    This paper presents a method to calculate probability distribution of HVDC capacity considering both repairable and aging failures of HVDC components. With integration of the aging failure mode, the capacity probability distribution is varied with years. It can be used as a multiple state model of HVDC links in transmission reliability evaluation. The expected capacity obtained from the capacity probability distribution is an index to quantify and prioritise importance of HVDC components in reliability centred maintenance.

  • Breakdown performance and electrical aging life model of EPR used in coal mining cables

    Ethylene Propylene Rubber (EPR) with excellent dielectric properties has been widely used as cable insulation specially to be used where cables need to be moved frequently, such as in coal mine. Usually, theses cables will be bending excessively, coupled with the electric stress and thermal stress, the aging of the insulation tend to accelerate and the strength of insulation could decrease, with the time prolonging, breakdown may be happened. So, it is necessary to make research on the breakdown characteristics of EPR. To understand the breakdown performance, a step-stress test method is used in the accelerated life tests of EPR and WEIBULL distribution is used to analyze the test dates. Finally, based on inverse power life model, the voltage life index of EPR have been obtained. Finally, the electrical aging life model of EPR have be obtained. Research on the breakdown characteristics and the voltage life index of EPR is significance for insulation structure design and residual life assessment.

  • A new estimation approach based on periodic inspection

    The authors present a novel approach for estimating the failure-time distribution using count data, the number of failures per interval, from periodic inspection of a standby redundant system. The procedure is based on a result for stationary renewal processes that related the forward recurrence time to the interevent time distribution. The procedure performed well in a simulation study for five Weibull distributions and is general enough to work for any failure-time distribution.<<ETX>>

  • Generalized phase crossing rate and random FM noise for Weibull fading channels

    In this paper, exact closed-form expressions are derived for the generalized phase crossing rate as well as for the crossing statistics of random frequency modulation (FM) noise in Weibull fading channels. These expressions specialize to those of the Rayleigh case, which are known in the literature. In addition, the conditional probability density functions of the envelope and the random FM noise conditioned on an arbitrary phase upward crossing level are obtained.
