Numerical Simulation of Magnetic Dipole Flow Over a Stretching Sheet in the Presence of Non-Uniform Heat Source/Sink
(
Frontiers Media
, 2021 , Article)
The main objective of current communication is to present a mathematical model and numerical simulation for momentum and heat transference characteristics of Maxwell nanofluid flow over a stretching sheet. Further, magnetic ...
An Efficient Robust Nonparametric Triple EWMA Wilcoxon Signed-Rank Control Chart for Process Location
(
Hindawi
, 2021 , Article)
The nonparametric (NP) control charts are famous for detecting a shift in the process parameters (location and/or dispersion) when the underlying process characteristic does not follow the distributional assumptions. ...
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 ...
Multivariate control charts for monitoring process mean vector of individual observations under regularized covariance estimation
(2021 , Article)
Multivariate control charts are generally used in industries for monitoring and diagnosing processes characterized by several process variables. The applications of charts assume that the in-control process parameters are ...
Simulation of natural convective heat transfer and entropy generation of nanoparticles around two spheres in horizontal arrangement
(
Elsevier
, 2021 , Article)
Herein, laminar convective heat transfer from two horizontally arranged spheres has been evaluated by using numerical models inside water-based fluids incorporated with alumina (Al2O3), copper oxide (CuO), and copper (Cu) ...
System of variational inequalities with interconnected obstacles
(
Taylor and Francis
, 2020 , Article)
Our objective with this paper is to discuss multi-switching problems, arising as variational inequalities, that models decision under uncertainty. We prove general existence theory through monotone scheme and discuss ...
A symmetric oscillator with multi-stability and chaotic dynamics: bifurcations, circuit implementation, and impulsive control
(
Springer
, 2021 , Article)
Finding chaotic oscillators with unique properties is a hot topic. In this paper, a symmetric oscillator with multi-stability is proposed. This oscillator has bounded dynamics for any initial conditions. It is also shown ...
Symmetric oscillator: Special features, realization, and combination synchronization
(
MDPI
, 2021 , Article)
Researchers have recently paid significant attention to special chaotic systems. In this work, we introduce an oscillator with different special features. In addition, the oscillator is symmetrical. The features and ...
Oyster oscillator: a novel mega-stable nonlinear chaotic system
(
Springer
, 2021 , Article)
Designing novel mega-stable chaotic oscillators has been a hot topic of research lately. In the current paper, a two-dimensional mega-stable oscillator is presented. The oscillator has a vast amount of coexisting limit ...
SARS-CoV-2 antibody-positivity protects against reinfection for at least seven months with 95% efficacy
(
Elsevier
, 2021 , Article)
Background Reinfection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been documented, raising public health concerns. SARS-CoV-2 reinfections were assessed in a cohort of antibody-positive persons ...
