Published in 2017 at "Neural Computing and Applications"

DOI: 10.1007/s00521-017-3064-y

Abstract: Control charts are the most applicable tools for monitoring the quality of processes. The day-to-day changes in industrial processes and customers’ expectations motivate the process engineers to monitor multiple correlated quality characteristics, simultaneously. Hence, in… read more here.

Published in 2018 at "Annals of Operations Research"

DOI: 10.1007/s10479-016-2186-4

Abstract: Traditional control charts assume a baseline parametric model, against which new observations are compared in order to identify significant departures from the baseline model. To monitor a process without a baseline model, real-time contrasts (RTC)… read more here.

Published in 2020 at "Journal of Ambient Intelligence and Humanized Computing"

DOI: 10.1007/s12652-020-01825-2

Abstract: The nature of VANET networks makes the network vulnerable to several attacks such as the black hole attack which is part of Denial of Service attacks (DOS). The aim of these attacks is to prohibit… read more here.

Published in 2017 at "Atmospheric Pollution Research"

DOI: 10.1016/j.apr.2017.01.004

Abstract: Abstract Outliers, which can have significant effects on further analysis and modelling, occur between continuously measured environmental data. Most methods for outlier detection depends on model or distribution of observed variable. However the distribution of… read more here.

Published in 2018 at "ISA transactions"

DOI: 10.1016/j.isatra.2018.04.020

Abstract: The control chart patterns are the most commonly used statistical process control (SPC) tools to monitor process changes. When a control chart produces an out-of-control signal, this means that the process has been changed. In… read more here.
