The Reliability, Validity and Normative Scores of the Bene-Anthony Family Relations Test for Use With Arab Children
(
Frontiers Media S.A.
, 2021 , Article)
Background: The Bene-Anthony Family Relations Test (BAFRT) is one of the most widely used measures of family dynamics seen from a child's perspective. However, the most common issue surrounding this test is the lack of ...
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 ...
A image encryption algorithm based on chaotic Lorenz system and novel primitive polynomial S-boxes
(
Springer
, 2021 , Article)
We have proposed a robust, secure and efficient image encryption algorithm based on chaotic maps and algebraic structure. Nowadays, the chaotic cryptosystems gained more attention due to their efficiency, the assurance of ...
Observer design for hyperbolic PDEs system with application to a fixed-bed chemical reactor model
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Conference Paper)
This work is devoted to the development of an optimal infinite-dimensional Luenberger observer for a system of hyperbolic PDEs. For this purpose, the duality fact linking the control design and the observer design is used. ...
Boundary optimal control design for a system of parabolic-hyperbolic PDEs coupled with an ODE
(
Taylor and Francis Ltd.
, 2020 , Article)
This paper deals with the design of a boundary optimal controller for a general model of parabolic-hyperbolic PDEs coupled with an ODE. The augmented infinite-dimensional state-space representation has been used in order ...
Sensitive SO2 gas sensor utilizing Pt-doped graphene nanoribbon: First principles investigation
(
Elsevier Ltd
, 2021 , Article)
The objective of this work is to seek a highly sensitive gas sensor for the detection of sulfur dioxide (SO2) by investigating the impacts of passivation as well as metal doping of armchair-edge graphene nanoribbon (AGNR) ...
Synchronization and chimeras in a network of photosensitive FitzHugh-Nagumo neurons
(
Springer Science and Business Media B.V.
, 2021 , Article)
Recently, a photosensitive model has been proposed that takes into account nonlinear encoding and responses of photosensitive neurons that are subject to optical signals. In the model, a photocell term has been added to ...
Proposing a Nondestructive and Intelligent System for Simultaneous Determining Flow Regime and Void Fraction Percentage of Gas-Liquid Two Phase Flows Using Polychromatic X-Ray Transmission Spectra
(
Springer
, 2021 , Article)
Two phase flows are of particular importance in various research fields. In the current article, a novel system consists of an X-ray tube and one sodium iodide crystal detector with ability of determining type of flow ...
SEIRD model for Qatar COVID-19 outbreak: A case study
(
Intercollegiate Biomathematics Alliance
, 2021 , Article)
The COVID-19 outbreak of 2020 has required many governments to develop mathematical-statistical models of the outbreak for policy and planning purposes. This work provides a tutorial on building a compartmental model using ...
Dynamical analysis of the delayed immune response to cancer
(
Elsevier
, 2021 , Article)
In the antitumor response, cytotoxic CD8 + T cells and the functional organization of CD4 + T cells play an important role. During this research, a mathematical model is built. In this model, the ability of CD4 + T cells, ...
