    • An adaptive thresholding-based process variability monitoring 

      Abdella G.M.; Kim J.; Kim S.; Al-Khalifa K.N.; Jeong M.K.M.K.; ... more authors ( Taylor and Francis Inc. , 2019 , Article)
      In high-dimensional processes, monitoring process variability is considerably difficult due to the large number of variables and the limited number of samples. Monitoring changes in the covariance matrix of a multivariate ...

    • Bayesian framework for fault variable identification 

      Turkoz M.; Kim S.; Jeong Y.-S.; Jeong M.K.; Elsayed E.A.; ... more authors ( Taylor and Francis Inc. , 2019 , Article)
      In most manufacturing processes, identifying the faulty process variables that may lead to process changes is crucial for quality engineers and practitioners. There are several parametric procedures for identifying faulty ...

    • Criticality measures for components with multi-dimensional degradation 

      Liu, X.; Al-Khalifa, K.N.; Elsayed, E.A.; Coit, D.W.; Hamouda, A.S. ( Taylor and Francis Ltd. , 2014 , Article)
      Failures of engineering structures and equipment are often attributed to the failure of a single component. Hence, it is important to identify critical components in a system and understand how a component's criticality ...

    • Monitoring and control of beta-distributed multistage production processes 

      Kim, S.; Kim, J.; Jeong, M. K.; Al-Khalifa, K. N.; Hamouda , A. M. S.; ... more authors ( Taylor and Francis Ltd. , 2019 , Article)
      Multistage statistical process control (SPC) is an effective procedure for ensuring quality of products in multistage manufacturing processes. Effective SPC approaches for monitoring and controlling quality in multistage ...

    • Multivariate statistical process control charts based on the approximate sequential ?2 test 

      Kim, J.; Al-Khalifa, K.N.; Jeong, M.K.; Hamouda, A.M.S.; Elsayed, E.A. ( Taylor and Francis Ltd. , 2014 , Article)
      Similar to the univariate CUSUM chart, a multivariate CUSUM (MCUSUM) chart can be designed to detect a particular size of the mean shift optimally based on the scheme of a sequential likelihood ratio test for the noncentrality ...

    • Reliability estimation of load sharing capacity-c-out-of-n pairs:G Balanced system 

      Hua, Dingguo; Elsayed, E. A.; Al-Khalifa, Khalifa N.; Hamouda, Abdelmagid S. ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)
      In many cases, systems are required to provide a specified capacity such as the case of power distribution system. A system fails when its capacity does not meet the required minimum capacity. In this paper, we investigate ...
