Fabrication and characterization of flexible ruthenium oxide-loaded polyaniline/poly(vinyl alcohol) nanofibers
(
Wiley
, 2020 , Article)
© 2020 Wiley Periodicals, Inc. Polyaniline/poly(vinyl alcohol)/ruthenium oxide (RuO2) composite nanofibers were produced by electrospinning technique. Hydrous ruthenium chloride was used as a precursor at different ...
New efficient exponentially weighted moving average variability charts based on auxiliary information
(
John Wiley and Sons Ltd
, 2020 , Article)
Control chart is a well-known tool for monitoring the performance of an ongoing process. The variability of a process is an important parameter that may deteriorate the process performance if it is not taken care on time. ...
Efficient bivariate EWMA charts for monitoring process dispersion
(
John Wiley and Sons Ltd
, 2020 , Article)
To ensure high quality standards of a process, the application of control charts to monitor process performance has become a regular routine. Multivariate charts are a preferred choice in the presence of more than one ...
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 ...
Efficient linear profile schemes for monitoring bivariate correlated processes with applications in the pharmaceutical industry
(
Elsevier
, 2020 , Article)
The complexity of chemical processes warrants that collection of information about the processes will continue as they proceed through the various stages of industrialization. Process monitoring has emerged as an essential ...
A hyperbolic penalty method to solve structured convex minimization problems
(
Institute of Advanced Science Extension (IASE)
, 2020 , Article)
This paper presents a decomposition algorithm based on the smooth hyperbolic penalty, which leads to a scheme suitable for parallelized computations. The proposed algorithm can be seen as a separable version of the earlier ...
A weighted version of Hermite-Hadamard type inequalities for strongly GA-convex functions
(
Institute of Advanced Science Extension (IASE)
, 2020 , Article)
In this paper, we have established new weighted Hermite-Hadamard type inequalities for strongly GA-convex functions. Those findings are obtained by using geometric symmetry of continuous positive mappings and differentiable ...
Robust index-tracking and enhanced index-tracking in portfolio optimization
(
Ascociacion Internacional de Economia Aplicada
, 2020 , Article)
We study index-tracking and enhanced index-tracking problems in portfolio optimization under interval uncertainty for returns and covariance matrix. The proposed robust counterparts for both models are in the form of second ...
The generalized trust-region sub-problem with additional linear inequality constraints-Two convex quadratic relaxations and strong duality
(
MDPI AG
, 2020 , Article)
In this paper, we study the problem of minimizing a general quadratic function subject to a quadratic inequality constraint with a fixed number of additional linear inequality constraints. Under a regularity condition, we ...
Large-scale global optimization based on hybrid swarm intelligence algorithm
(
IOS Press
, 2020 , Article)
There are numerous large-scale global optimization problems encountered in real-world applications including engineering, manufacturing, economics, networking fields. Over the last two decades different varieties of swarm ...
