Prediction and Comparative Analysis of Thermal Conductivity of Jatropha Oil-based Hybrid Nanofluid by Multivariable Regression and ANN
Abstract: In the present study, a multivariable regression (MR) and artificial neural network (ANN) method was used to predict the thermal conductivity of Jatropha oil-based ZnO-Ag hybrid nanofluid. Firstly, the ZnO-Ag hybrid nanoparticles were synthesized and mixed in the jatropha oil to prepare various nanofluids at different volume concentrations (F) ranging from 0.05 to 0.20%. The stability and thermal conductivity of the prepared nanofluids were investigated. Wide ranges of temperature and …

Robust Regression Models for Identifying Outliers in Medical Data
Abstract: Before applying any multivariate statistical analysis, it is important to determine whether outliers are present in the dataset. In regression analysis, the presence of outliers in the dataset can strongly mislead the classical least squares estimator and lead to unreliable results. In this paper, we prove the minimum covariance determinant estimator, which is commonly applied in a robust statistic to estimate location parameters and multivariate scales. These ideas can be …

Prevalence of Frailty and Its Association with Information and Communication Technologies Use among Older Adults
Abstract: Frailty phenotype (FP) refers to a clinical syndrome characterized by a lack of effective response to stressors due to a decline in physiological reserve. The presence of FP is associated with negative outcomes in elders, like disability. Information and communication technology (ICT) is defined as a unit of technology that an individual can use to produce, store, and communicate information, e.g., mobile phones (MP) and internet browsing. The aim of …
