Discontinuous coupling and transition from synchronization to an intermittent transient chimera state
(
Sharif University of Technology
, 2021 , Article)
Coexistence of coherent and incoherent clusters, called chimera state, has been observed in different coupling configurations. A majority of studies have considered a static scheme for the network. In this paper, synchronization ...
Measuring skewness: We do not assume much
(
Sharif University of Technology
, 2021 , Article)
Since skewness plays a vital role in different engineering phenomena, its accurate measurement gains significance. Several measures have been taken to quantify the extent of skewness in distributions over the years, but ...
An efficient image encryption scheme based on double affine substitution box and chaotic system
(
Elsevier
, 2021 , Article)
Privacy of information is one of the most important and unavoidable issues in our digitally advance era. A huge amount of information transmitted over different servers and networking protocols. The sphere of digitally ...
SARS-CoV-2 infection hospitalization, severity, criticality, and fatality rates in Qatar
(
Nature Research
, 2021 , Article)
The SARS-CoV-2 pandemic resulted in considerable morbidity and mortality as well as severe economic and societal disruptions. Despite scientific progress, true infection severity, factoring both diagnosed and undiagnosed ...
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 ...
Computation of conformal invariants
(
Elsevier
, 2020 , Article)
We study numerical computation of conformal invariants of domains in the complex plane. In particular, we provide an algorithm for computing the conformal capacity of a condenser. The algorithm applies to a wide variety ...
Application of integral equations to simulating local fields in carbon nanotube reinforced composites
(
Elsevier
, 2020 , Book chapter)
We consider the steady heat conduction problem within a thermal isotropic and homogeneous square ring composite reinforced by nonoverlapping and randomly distributed carbon nanotubes (CNTs). We treat the CNTs as rigid line ...
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 ...
Duality-based optimal compensator for boundary control hyperbolic PDEs system: Application to a tubular cracking reactor
(
Elsevier
, 2020 , Article)
This paper is devoted to the design of an optimal stabilizing compensator for a boundary control distributed parameter system that is described by a set of hyperbolic partial differential equations (PDEs). The standard ...
Optimal control and duality-based observer design for a hyperbolic PDEs system with application to fixed-bed reactor
(
Taylor and Francis Ltd.
, 2021 , Article)
This paper is devoted to the design of an optimal infinite-dimensional Luenberger observer combined with a linear-quadratic state feedback controller for a system of hyperbolic PDEs. The design is based on the duality fact ...
