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 ... -
Erratum to: Two-stage complete allocation sampling (Environmetrics, (2017), 28, 3, (e2441), 10.1002/env.2441)
( John Wiley and Sons Ltd , 2017 , Other)This article corrects: Salehi MM, Seber GAF. Two-stage complete allocation sampling. Environmetrics. 2017;28:e2441. https://doi.org/10.1002/env.2441. The main correction is on the introduced unbiased estimator of the ... -
Error analysis associated with uniform Hermite interpolations of bandlimited functions
( Korean Mathematical Society , 2010 , Article)We derive estimates for the truncation, amplitude and jitter type errors associated with Hermite-type interpolations at equidistant nodes of functions in Paley-Wiener spaces. We give pointwise and uniform estimates. Some ... -
Error-feedback regulation of a distributed parameter cracking process by using a spectral approach
( Institute of Electrical and Electronics Engineers Inc. , 2023 , Conference Paper)The paper focuses on controlling a distributed parameter cracking process using state and error feedback regulators. The principal aim is to accomplish tracking of a desired output while effectively managing disturbances ... -
Estimates of global SARS-CoV-2 infection exposure, infection morbidity, and infection mortality rates in 2020
( Elsevier , 2021 , Article)We aimed to estimate, albeit crudely and provisionally, national, regional, and global proportions of respective populations that have been infected with SARS-CoV-2 in the first year after the introduction of this virus ... -
Estimating protection afforded by prior infection in preventing reinfection: Applying the test-negative study design.
( Oxford University Press , 2023 , Article)The COVID-19 pandemic has highlighted the need to use infection testing databases to rapidly estimate effectiveness of prior infection in preventing reinfection ($P{E}_S$) by novel SARS-CoV-2 variants. Mathematical modeling ... -
Estimation of common location parameter of two exponential populations based on records
( Taylor and Francis Inc. , 2018 , Article)Consider the problem of estimating the common location parameter of two exponential populations using record data when the scale parameters are unknown. We derive the maximum likelihood estimator (MLE), the modified maximum ... -
Estimation of health-related quality of life in the presence of missing Values in EQ-5D
( Hindawi Limited , 2021 , Article)One of the notes worthy problems in analysis of clinical and observational studies is missing data and nonresponse from patients. Turning a blind eye to the missing behavior may provide biased results with overestimated ... -
Estimation of Pr(X ≤ Y) using record values in the one and two parameter exponential distributions
( Taylor & Francis , 2008 , Article)Abstract We consider the problem of estimating the stress-strength reliability when the available data is in the form of record values. The one parameter and two parameters exponential distribution are considered. In the ... -
ESTIMATION OF THE LOCATION-SCALE PARAMETERS BASED ON RANKED SET SAMPLING COMBINED WITH ADDITIONAL BINOMIAL INFORMATION
( ISOSS PUBLICATIONS , 2023 , Article)In this paper, we propose a modified version of ranked set sample which allows for the incorporation of more information in the inference procedure at almost no cost. This procedure is studied for the location-scale family ... -
Estimation procedures based on preliminary test in exponential distribution under progressive censoring
( Nova Science Publishers, Inc. , 2016 , Article)This paper considers the preliminary test estimator of the unknown parameter of the exponential distribution based on progressively Type-II censored samples. The mean squared error of the proposed estimator is derived and ... -
Evaluating the Online Learning Experience at Higher Education Institutions
( IGI Global , 2022 , Article)In light of recent COVID-19 pandemic, universities had to cope by resorting to online learning without previous preparation. This paper tries to investigate student satisfaction with online learning. The literature review ... -
Existence and approximation results for SKC mappings in CAT(0) spaces
( Springer International Publishing , 2014 , Article)Recently, Karap?nar and Tas (Comput. Math. Appl. 61:3370-3380, 2011) extended the class of Suzuki-generalized nonexpansive mappings to the class of SKC mappings. In this paper, we investigate SKC mappings to get a criterion ... -
