Spectral-based optimal output-feedback boundary control of a cracking catalytic reactor PDE model
(
Taylor and Francis Ltd.
, 2024 , Article)
This research paper focuses on the design of a boundary optimal controller with output feedback for a tubular catalytic cracking reactor. The process is represented by a set of non-linear parabolic partial differential ...
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) ...
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 ...
Cryptanalysis of nonlinear confusion component based encryption algorithm
(
Elsevier
, 2021 , Article)
Recently many substitution box based encryption algorithms ensuring privacy have been proposed. Many, chaotic map based S-boxes have been generated posing high nonlinearity and strong cryptographic properties. Encryption ...
Application of artificial intelligence and gamma attenuation techniques for predicting gas-oil-water volume fraction in annular regime of three-phase flow independent of oil pipeline's scale layer
(
MDPI AG
, 2021 , Article)
To the best knowledge of the authors, in former studies in the field of measuring volume fraction of gas, oil, and water components in a three-phase flow using gamma radiation technique, the existence of a scale layer has ...
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 ...
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 ...
Linear hydrogen gas sensors based on bimetallic nanoclusters
(
Elsevier Ltd
, 2016 , Article)
This work reports on the fabrication of hydrogen gas sensors based on bimetallic palladium-copper nanoclusters. The nanoclusters were generated by sputtering and inert-gas condensation inside an ultra-high vacuum (UHV) ...
A point symmetry based method for transforming ODEs with three-dimensional symmetry algebras to their canonical forms
(
Elsevier Inc.
, 2016 , Article)
We provide an algorithmic approach to the construction of point transformations for scalar ordinary differential equations that admit three-dimensional symmetry algebras which lead to their respective canonical forms.
Instability of Langmuir-beam waves: Kappa-distributed electrons
(
American Institute of Physics Inc.
, 2023 , Article)
In space plasmas, electron populations exhibit non-equilibrium velocity distributions with high-energy tails that are reproduced by the Kappa power-laws and contrast with the Maxwellian distributions often used in theoretical ...
