An adaptive thresholding-based process variability monitoring
Abdella G.M.; Kim J.; Kim S.; Al-Khalifa K.N.; Jeong M.K.M.K.; Hamouda A.M.; Elsayed E.A.... more authors ... less 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.; Al-Khalifa K.N.; Hamouda A.M.... more authors ... less 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 ... -
Control charts for variability monitoring in high-dimensional processes
Kim J.; Abdella G.M.; Kim S.; Al-Khalifa K.N.; Hamouda A.M. ( Elsevier Ltd , 2019 , Article)Monitoring process variability is associated with detecting changes in the covariance matrix of a multivariate normal process. Most monitoring methods estimate the sample covariance matrix and compare it with the in-control ... -
Estimating the carbon dynamics of South Korean forests from 1954 to 2012
Lee, J.; Yoon, T.K.; Han, S.; Kim, S.; Yi, M.J.; Park, G.S.; Kim, C.; Son, Y.M.; Kim, R.; Son, Y.... more authors ... less authors ( Copernicus GmbH , 2014 , Article)Forests play an important role in the global carbon (C) cycle, and the South Korean forests also contribute to this global C cycle. While the South Korean forest ecosystem was almost completely destroyed by exploitation ... -
High-Efficiency Solar Desalination Accompanying Electrocatalytic Conversions of Desalted Chloride and Captured Carbon Dioxide
Kim B.-J.; Piao G.; Kim S.; Yang S.Y.; Park Y.; Han D.S.; Shon H.K.; Hoffmann M.R.; Park H.... more authors ... less authors ( American Chemical Society , 2019 , Article)The sustainability of conventional water- and energy-associated systems is being examined in terms of water-energy nexus. This study presents a high-efficiency, off-grid solar desalination system for saline water (salinities ... -
Monitoring and control of beta-distributed multistage production processes
Kim, S.; Kim, J.; Jeong, M. K.; Al-Khalifa, K. N.; Hamouda , A. M. S.; Elsayed, E. A.... more authors ... less 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 ... -
Solar hydrogen peroxide production on carbon nanotubes wired to titania nanorod arrays catalyzing As(III) oxidation
Choi S.Y.; Kim S.; Lee K.J.; Kim J.Y.; Han D.S.; Park H.... more authors ... less authors ( Elsevier B.V. , 2019 , Article)We present an off-grid, standalone electrocatalytic H2O2 production reaction (HPR) using carbon nanotubes (CNT) wired to hydrogen-treated TiO2 nanorod (h-TNR) arrays catalyzing the oxidation of As(III) to As(V) under ...
