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 ... -
Existence of a tripled coincidence point in ordered Gb-metric spaces and applications to a system of integral equations
( Springer , 2013 , Article)In this paper, tripled coincidence points of mappings satisfying some nonlinear contractive conditions in the framework of partially ordered G b-metric spaces are obtained. Our results extend the results of Aydi et al. ... -
The explicit eigenvalues and eigenfunctions of the generalized neumann kernel in annular domains
( Universiti Putra Malaysia , 2019 , Article)This paper presents the explicit forms of the eigenvalues of the general-ized Neumann kernel in annular domains and the explicit forms of the corresponding eigenfunctions. It follows from these explicit forms that, except ... -
EXPLORATION of the NOVEL CORONA VIRUS TRANSITION GRAPHS with PETRINET MODELING
( World Scientific Publishing , 2021 , Article)Corona virus (CoV) is a group of viruses with non-bifurcated, single-stranded, and positive-sense RNA genomes. Apart from infecting several economically significant vertebrates (such as pigs and chickens), it is reported ... -
Exponentially weighted moving average control charts for monitoring coefficient of variation under ranked set-sampling schemes
( Taylor and Francis , 2021 , Article)Several coefficients of variation (CV) control charts under simple random schemes (SRS) have been proposed to monitor process relative variability. However, little attention has been given to investigating the performance ... -
Extended rectangular b-metric spaces and some fixed point theorems for contractive mappings
( MDPI AG , 2019 , Article)In this paper, we introduce the class of extended rectangular b-metric spaces as a generalization of both rectangular metric and rectangular b-metric spaces. In addition, some fixed point results connected with certain ... -
