A non-parametric double homogeneously weighted moving average control chart under sign statistic
( John Wiley and Sons Ltd , 2021 , Article)In practical situations, the underlying process distribution sometimes deviates from normality and their distribution is partially or completely unknown. In that instance, rather than staying with/depending on the conventional ... -
An Improved Control Chart for Monitoring Linear Profiles and its Application in Thermal Conductivity
( Institute of Electrical and Electronics Engineers Inc. , 2020 , Article)In most of the manufacturing processes, we encounter different quality characteristics of a product and process. These characteristics can be categorized into two kinds; study variables (variable of interest) and the ... -
Efficacy and safety of tocilizumab in COVID-19 patients: a living systematic review and meta-analysis, first update
( Elsevier , 2021 , Article)ObjectivesCytokine release syndrome with elevated interleukin-6 (IL-6) levels is associated with multiorgan damage and death in severe coronavirus disease 2019 (COVID-19). Our objective was to update the data in a living ... -
Efficient and distribution-free charts for monitoring the process location for individual observations
( Taylor and Francis Ltd. , 2024 , Article)Sudden and sequential variations are crucial in industrial and production processes. To track these consistent changes in process parameters, effective charting methods are needed. The generally weighted moving average ... -
New efficient exponentially weighted moving average variability charts based on auxiliary information
( John Wiley and Sons Ltd , 2020 , Article)Control chart is a well-known tool for monitoring the performance of an ongoing process. The variability of a process is an important parameter that may deteriorate the process performance if it is not taken care on time. ... -
On designing an assorted control charting approach to monitor process dispersion: an application to hard-bake process
( Taylor and Francis Ltd. , 2020 , Article)The monitoring of process variability is an important feature to get optimal output from a process. Control charts are vital tools used for efficient process monitoring. The commonly used types of charts include Shewhart, ... -
One-Sided and Two One-Sided Multivariate Homogeneously Weighted Moving Charts for Monitoring Process Mean
( Institute of Electrical and Electronics Engineers Inc. , 2021 , Article)Multivariate memory-type control charts that use information from both the current and previous process observations have been proposed. They are designed to detect shifts in both upper and downward directions with equal ... -
Online monitoring of climatic parameters: a statistical study about environmental changes in Qatar
( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference)Twentieth century has witnessed unprecedented changes in the climate whose profound effects are also observed on ecosystem and human life. The source of these changes are presumed to be increasing concentration of greenhouse ... -
Prior Statins Use and Risk of Mortality and Severe Disease from COVID-19: A Systematic Review and Meta-Analysis
( Oxford University Press , 2021 , Article)Background Statins up-regulate angiotensin converting enzyme-2, the receptor of SARS-CoV-2, while also exhibiting pleiotropic antiviral, antithrombotic and anti-inflammatory properties. Uncertainties exist about their ...
