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 ...
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. ...
Optical biosensor based on ultrathin SOI waveguides
(
Optica Publishing Group (formerly OSA)
, 2020 , Conference Paper)
We introduce an optical biosensor utilizing the MMI configuration and based on the ultrathin SOI platform. The biosensor was optimized using finite difference time domain simulations. A sensitivity of 420 nm/RIU was achieved.
Facile one-step synthesis of supportless porous AuPtPd nanocrystals as high performance electrocatalyst for glucose oxidation reaction
(
Elsevier
, 2020 , Article)
Direct glucose fuel cells (DGFCs) received great interest due to non-toxicity, low cost, and renewability. Herein, we demonstrated the synthesis of novel porous AuPtPd nanocrystals (NCs) via plausible one-pot synthesis ...
Highly porous PtPd nanoclusters synthesized via selective chemical etching as efficient catalyst for ethanol electro-oxidation
(
Elsevier
, 2020 , Article)
Direct ethanol fuel cells (DEFCs) have received great interest owing to their high power density and environmental friendness. Nevertheless, the designing of active, durable, and efficient anode for DEFCs is a profound ...
Photoelectrocatalytic hydrogen production on ternary Co-Pi/Ag/TiON nanotube array photocatalysts
(
John Wiley and Sons Ltd
, 2021 , Article)
Ternary Co-Pi-Ag/TiON photocatalysts were designed and fabricated by a facile precipitation and electrochemical strategy. The results showed the superiority of the Co-Pi-Ag/TiON as a promising photoanode for photoelectrochemical ...
