Phytoplankton along the coastal shelf of an oligotrophic hypersaline environment in a semi-enclosed marginal sea: Qatar (Arabian Gulf)
(
Elsevier
, 2013 , Article)
Phytoplankton biomass (chlorophyll a concentration), primary production, abundance, species diversity and species groupings were measured in the coastal waters surrounding Qatar (Arabian Gulf) at 13 stations in February ...
Control of parabolic PDEs with time-varying spatial domain: Czochralski crystal growth process
(
Taylor and Francis Ltd.
, 2013 , Article)
This paper considers the optimal control problem for a class of convection-diffusion-reaction systems modelled by partial differential equations (PDEs) defined on time-varying spatial domains. The class of PDEs is characterised ...
Boundary optimal control of coupled parabolic PDE-ODE systems
(
IFAC Secretariat
, 2014 , Conference Paper)
This paper deals with boundary optimal control problem for coupled parabolic PDEODE systems. The problem is studied using infinite-dimensional state space representation of the coupled PDE-ODE system. Linearization of the ...
Infinite-dimensional LQ optimal control of a dimethyl ether (DME) catalytic distillation column
(
Elsevier
, 2012 , Article)
This contribution addresses the development of a linear quadratic (LQ) regulator in order to control the concentration profiles along a catalytic distillation column, which is modelled by a set of coupled hyperbolic partial ...
Boundary optimal (LQ) control of coupled hyperbolic PDEs and ODEs
(
Elsevier
, 2013 , Article)
This contribution addresses the development of a linear quadratic (LQ) regulator for a set of hyperbolic PDEs coupled with a set of ODEs through the boundary. The approach is based on an infinite-dimensional Hilbert ...
Optimal control of an advection-dominated catalytic fixed-bed reactor with catalyst deactivation
(
Elsevier
, 2013 , Article)
The paper focuses on the linear-quadratic control problem for a time-varying partial differential equation model of a catalytic fixed-bed reactor. The classical Riccati equation approach, for time-varying infinite-dimensional ...
Model predictive control of selective catalytic reduction in diesel-powered vehicles
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
This paper proposes a method to synthesize an optimal controller for the SCR section of the diesel exhaust after-treatment system, which is based on a system model consisting of coupled hyperbolic and parabolic partial ...
Optimal boundary control of coupled parabolic PDE-ODE systems using infinite-dimensional representation
(
Elsevier
, 2015 , Article)
The optimal boundary control problem is studied for coupled parabolic PDE-ODE systems. The linear quadratic method is used and exploits an infinite-dimensional state-space representation of the coupled PDE-ODE system. ...
Single-step feedback linearization with assignable dynamics for hyperbolic PDE
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
The present work proposes an extension of single-step feedback linearization with pole-placement formulation to the class of nonlinear hyperbolic systems. In particular, the mathematical formulation in the context of ...
Microfluidic devices with modified electrochemical detection for biomarkers analysis: A review
(
Nova Science Publishers, Inc.
, 2014 , Book chapter)
Integrated microfluidic systems continue to garner a great deal of attention. This interest can be attributed to the advantages that these microsystems exhibit over conventional separation and detection systems while ...
