Solving a class of integral equations via contractive mapping with rational type
(
New York Business Global
, 2020 , Article)
In this paper, using rational type contractive conditions, the existence and uniqueness of common coupled fixed point theorem in the set up of Gb-metric spaces is studied. The derived result cover and generalize some ...
Association of Prior SARS-CoV-2 Infection With Risk of Breakthrough Infection Following mRNA Vaccination in Qatar.
(
American Medical Association
, 2021 , Article)
The effect of prior SARS-CoV-2 infection on vaccine protection remains poorly understood. To assess protection from SARS-CoV-2 breakthrough infection after mRNA vaccination among persons with vs without prior SARS-CoV-2 ...
Efficient homogeneously weighted dispersion control charts with an application to distillation process
(
Wiley
, 2021 , Article)
Monitoring disturbances in process dispersion using control chart is mostly based on the assumption that the quality characteristic follows normal distribution, which is not the case in many real-life situations. This paper ...
Multivariate control charts for monitoring process mean vector of individual observations under regularized covariance estimation
(2021 , Article)
Multivariate control charts are generally used in industries for monitoring and diagnosing processes characterized by several process variables. The applications of charts assume that the in-control process parameters are ...
Forecasting the impact of environmental stresses on the frequent waves of COVID19
(
Springer
, 2021 , Article)
A novel approach to link the environmental stresses with the COVID-19 cases is adopted during this research. The time-dependent data are extracted from the online repositories that are freely available for knowledge and ...
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. ...
Symmetric oscillator: Special features, realization, and combination synchronization
(
MDPI
, 2021 , Article)
Researchers have recently paid significant attention to special chaotic systems. In this work, we introduce an oscillator with different special features. In addition, the oscillator is symmetrical. The features and ...
A new hwma dispersion control chart with an application to wind farm data
(
MDPI AG
, 2020 , Article)
Recently, a homogeneously weighted moving average (HWMA) chart has been suggested for the efficient detection of small shifts in the process mean. In this study, we have proposed a new one-sided HWMA chart to effectively ...
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 ...
Enhanced remediation of Cr6+ in bacterial-assisted floating wetlands
(
Blackwell Publishing Ltd
, 2020 , Article)
Hexavalent chromium (Cr6+) is reported to have negative effects on fauna and flora. The present study establishes plant-bacterial synergism in floating wetlands (FWs) for the maximum removal of Cr6+ from the contaminated ...
