Auxiliary-information-based efficient variability control charts for Phase I of SPC
(
John Wiley and Sons Ltd
, 2020 , Article)
The inclusion of correlated auxiliary variables into the monitoring scheme of quality characteristic of interest has gained notable attention in recent statistical process control (SPC) literature. Several authors have ...
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 ...
CO, CO2, and SO2 detection based on functionalized graphene nanoribbons: First principles study
(
Elsevier
, 2020 , Article)
In this study, density functional theory (DFT) has been used to build armchair graphene nanoribbon (AGNR) gas sensor and study its capacity to detect carbon monoxide (CO), carbon dioxide (CO2), and sulfur dioxide (SO2) ...
Production of flexible nanocomposite membranes for x-ray detectors
(
Elsevier
, 2020 , Article)
Flexible membranes of poly(vinyl alcohol) (PVA) polymer and CuO nanoparticles for x-ray detection applications are reported in this work. PVA represents a polymer matrix for nanoparticles, and its flexibility and electrical ...
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 ...
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 ...
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 ...
First principle investigation of H2Se, H2Te and PH3 sensing based on graphene oxide
(
Elsevier
, 2020 , Article)
Detecting toxic gases is of great importance to protect our health and preserve the quality of life. In this work, graphene (G) and graphene oxide with three different modifications (G–O, G–OH, and G–O–OH) have been used ...
Effects of ambient climate and three warming treatments on fruit production in an alpine, subarctic meadow community
(
Wiley
, 2021 , Article)
Premise
Climate change is having major impacts on alpine and arctic regions, and inter‐annual variations in temperature are likely to increase. How increased climate variability will impact plant reproduction is ...
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 ...
