Error-feedback regulation of a distributed parameter cracking process by using a spectral approach
(
Institute of Electrical and Electronics Engineers Inc.
, 2023 , Conference Paper)
The paper focuses on controlling a distributed parameter cracking process using state and error feedback regulators. The principal aim is to accomplish tracking of a desired output while effectively managing disturbances ...
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) ...
Using Grades in Core Curriculum Chain Courses as Predictors of Academic Performance in Subsequent Courses: A Study at Qatar University
(
SAGE Publications Inc.
, 2023 , Article)
The study aimed to investigate students' final grades in a linked course or chain course to determine any effect on students' academic performance in their next linked course. Courses with high D, F, and W grades were ...
On the boundedness of rough oscillatory singular integrals on Triebel-Lizorkin spaces
(
springer link
, 2011 , Article)
We obtain appropriate sharp bounds on Triebel-Lizorkin spaces for rough oscillatory integrals with polynomial phase. By using these bounds and using an extrapolation argument we obtain some new and previously known results ...
Optimization of tank engine crank shaft material properties
(
Taylor and Francis Ltd.
, 2023 , Article)
Metals and coating materials, with best material properties are highly desired in the field of engineering to control the stresses and strains, that play important role in design strategies. The crankshaft, an important ...
Positron annihilation lifetime study of helium ions implanted polyethylene blends
(
Trans Tech Publications Ltd
, 2004 , Conference Paper)
The structural defects of linear low density polyethylene (LLDPE) and high density polyethylene (HOPE) blends implanted with helium ions were investigated using position annihilation lifetime (PAL) technique. The positron ...
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 ...
Microstructure of heat-treated steel probed by positron annihilation
(2001 , Conference Paper)
Positron annihilation lifetime technique has been applied to study the microstructure change in steel after heat treatment. For this purpose, the specimens are heat treated in various manners; normalizing, annealing, ...
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.
