Employing machine learning techniques in monitoring autocorrelated profiles
( Springer Science and Business Media Deutschland GmbH , 2023 , Article)In profile monitoring, it is usually assumed that the observations between or within each profile are independent of each other. However, this assumption is often violated in manufacturing practice, and it is of utmost ... -
Endpoint Estimates for Oscillatory Singular Integrals with H�lder Class Kernels
( Hindawi Limited , 2019 , Article)We prove the uniform L1?L1,? and HE 1?L1 boundedness of oscillatory singular integral operators whose kernels are the products of an oscillatory factor with bilinear phase and a Calder�n-Zygmund kernel K(x,y) satisfying a ... -
Engineering the band gap of BN and BC2N nanotubes based on T-graphene sheets using a transverse electric field: Density functional theory study
( Elsevier , 2022 , Article)A new class of nanotubes formed by rolling boron nitride (BN) and boron carbonitride (BC2N) sheets in the form of T-graphene is suggested in this work. The structural and electronic properties of these nanotubes, named ... -
Enhanced adaptive multivariate EWMA and CUSUM charts for process mean
( Taylor and Francis Ltd. , 2021 , Article)The multivariate charts are mostly used to simultaneously monitor several quality characteristics in manufacturing processes. In this study, we enhance the sensitivities of the recently proposed adaptive multivariate EWMA ... -
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 ... -
Enhancing passive UHF RFID backscatter energy using chirp spread spectrum signals and channel shortening
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)Performance of passive ultrahigh frequency radio-frequency identification (UHF RFID) systems depends on the energy level of the backscattered signal from the RF tag to the RFID reader. In the indoor environment, the ... -
Enhancing the detection ability of control charts in profile monitoring by adding RBF ensemble model
( Springer Science and Business Media Deutschland GmbH , 2022 , Article)While numerous contributions and applications have been extended in profile monitoring, little attention has been paid to employing machine learning techniques in development of control charts. In this paper, a novel control ... -

Enhancing the performance of the EWMA control chart for monitoring the process mean using auxiliary information
( John Wiley and Sons Ltd , 2019 , Article)When using control charts to monitor manufacturing processes, the exponentially weighted moving average (EWMA) control chart is useful for detecting persistent shifts in the process parameter. This paper proposes enhancements ... -
Enhancing the Sensing Performance of Zigzag Graphene Nanoribbon to Detect NO, NO, and NH Gases.
( MDPI , 2020 , Article)In this article, a zigzag graphene nanoribbon (ZGNR)-based sensor was built utilizing the Atomistic ToolKit Virtual NanoLab (ATK-VNL), and used to detect nitric oxide (NO), nitrogen dioxide (NO), and ammonia (NH). The ... -
Entropy analysis and image encryption application based on a new chaotic system crossing a cylinder
( MDPI AG , 2019 , Article)Designing chaotic systems with specific features is a hot topic in nonlinear dynamics. In this study, a novel chaotic system is presented with a unique feature of crossing inside and outside of a cylinder repeatedly. This ... -
Entropy-Like Minimization Methods Based on Modified Proximal Point Algorithm
( University of Toronto Press Inc. , 2014 , Article)In this paper we introduce an extension of the proximal point algorithm proposed by Guler for solving convex minimization problems. This extension is obtained by substituting the usual quadratic proximal term by a class ... -
Epidemiological impact of prioritising SARS-CoV-2 vaccination by antibody status: Mathematical modelling analyses
( BMJ Publishing Group , 2021 , Article)Background Vaccines against SARS-CoV-2 have been developed, but their availability falls far short of global needs. This study aimed to investigate the impact of prioritising available doses on the basis of recipient ... -
