Efficient GLM-based control charts for Poisson processes
(
John Wiley & Sons, Ltd
, 2022 , Article)
The control charts are essential instruments that can impart crucial insights to quality controllers for maintaining the productivity of manufacturing processes. The conventional charting designs are based on a single study ...
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 ...
On Indefinite Quadratic Optimization over the Intersection of Balls and Linear Constraints
(
Springer
, 2022 , Article)
In this paper, we study the minimization of an indefinite quadratic function over theintersection of balls and linear inequality constraints (QOBL). Using the hyperplanesinduced by the intersection of each pair of balls, ...
Modified Profile Likelihood Estimation in the Lomax Distribution
(
Horizon Research Publishing
, 2022 , Article)
In this paper, we consider improving maximum likelihood inference for the scale parameter of the Lomax distribution. The improvement is based on using modifications to the maximum likelihood estimator based on the ...
Modeling the population-level impact of treatment on COVID-19 disease and SARS-CoV-2 transmission
(
Elsevier
, 2022 , Article)
Different COVID-19 treatment candidates are under development, and some are becoming available including two promising drugs from Merck and Pfizer. This study provides conceptual frameworks for the effects of three types ...
Tunable Hydroxyapatite/Magnetite Nanohybrids with Preserved Magnetic Properties
(
Wiley
, 2022 , Article)
Magnetic nanoparticles (MNPs) have been extensively investigated in a wide range of biomedical applications. Controlled coating of the MNPs is commonly utilized to protect and maintain their magnetic properties and to ...
Investigation on inlet obstruction in transitional flow regime: Heat transfer augmentation and pressure drop analysis
(
Elsevier
, 2022 , Article)
Thermohydraulic characteristics of air as the working medium in a circular heated channel fitted with inlet obstruction (ribbed prism) at the inlet is carried out experimentally for transitional flow regime. The ribbed ...
