A Comparison of Copulas Based on the Range Distribution and Its Application Open
This paper compares some Archimedean Copulas based on the range distribution and its application. We show that the Clayton Copula is better than the other Copula models considered in this paper. Also, Clayton Copula performed better than t…
Development of a predictive model for thermal conductivity in graphene nanoplatelets-infused damper oil using ANN/RSM Open
This study aims to develop a predictive model for the thermal conductivity of graphene nanoplatelets/SAE10W oil nanofluids using artificial neural networks (ANN) and response surface methodology (RSM). Generally, the property of thermal co…
A Copula Based Investigation of Reliability for the Multivariate Exponential Family of Distributions Open
This paper explores the possibility for using the copulas in the context of evaluating the reliability for the exponential family of distributions.
On the Use of Copula for Quality Control Based on an AR(1) Model Open
Manufacturing for a multitude of continuous processing applications in the era of automation and ‘Industry 4.0’ is focused on rapid throughput while producing products of acceptable quality that meet customer specifications. Monitoring the…
A Diagnostic Test Based on a 9-Component Mixture Gaussian Copula Model Open
Here in this paper, we investigate the performance of a diagnostic test based on a mixture Gaussian Copula which incorporates a Markov Chain. Suppose that in the context of an infectious disease, there are three states; Susceptible (S), In…
A Comparison of Archimedean Copula Models for approximating Bivariate Skew-Normal Distribution Open
This paper compares the performance of some Archimedean Copulas in approximating the bivariate skew-normal distribution. Our study shows Frank Copula is a better Archimedean Copula for approximating the bivariate skew-normal distribution.
Mathematical modeling and simulation of longitudinal road profiles Open
The excitations caused by the road roughness is the main parameter for the vertical vibrations generated in a vehicle. Their influence in the ride comfort of passengers and vehicle stability is high. It is essential to quantify road excita…
Multiphysics Analysis of a Magnetorheological Damper Open
A Magnetorheological damping has evolved as a potential tool in vibration control. The design of magnetorheological damping involves analysis of fluid flow principles and electromagnetic flux analysis. This research paper involves design a…
STEM/Non-STEM Divide Structures Undergraduate Beliefs About Gender and Talent in Academia Open
Research and popular debate on female underrepresentation in academia has focused on STEM fields. But recent work has offered a unifying explanation for gender representation across the STEM/non-STEM divide. This proposed explanation, call…
On the Error Rate Comparison of the Quadratic Discriminant Function, Euclidean Distance Classifier, Fisher’s Linear Discriminant Function and the Vine Copulas Open
The estimation of the error rates is of vital importance in classification problems as this is used as a basis to choose the best discriminant function; that is, the one with a minimum misclassification error. The quadratic discriminant fu…
A Copula Based Test for a Two Component Bivariate Mixture Distribution Open
The paper presents a Copula based approach to test for a two component bivariate mixture distribution. The regular joint density is modeled by using the Copula and then the Locally Most Powerful test (LMP) test is derived by using this Cop…
Multivariate Kurtosis as a Tool for Comparing Copula Models Open
This paper studies the effectiveness of the Multivariate Kurtosis in comparing the Clayton Copula and the Farleigh-Gumbel-Morgenstern Copula in modeling when the actual populations follow either the bivariate exponential distribution or th…
