Investigations of He <sup>+</sup> implantation and subsequent annealing effects in InP
(
Elsevier
, 2006 , Article)
The influence of 70 keV He + ion implantation and subsequent annealing of Cz-indium phosphide (InP) samples has been investigated using a slow positron beam-based Doppler broadening spectrometer. Three samples with ion ...
Self-implantation of Cz-Si: Clustering and annealing of defects
(
Elsevier
, 2006 , Article)
Observations of vacancy clusters formed in Czochralski (Cz) Si after high energy ion implantation are reported. Vacancy clusters were created by 2 MeV Si ion implantation of 1 × 10 15 ions/cm 2 and after annealing between ...
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 ...
Penalty ADM Algorithm for Cardinality Constrained Mean-Absolute Deviation Portfolio Optimization
(
International Academic Press
, 2022 , Article)
In this paper, we study the cardinality constrained mean-absolute deviation portfolio optimization problem with risk-neutral interest rate and short-selling. We enhance the model by adding extra constraints to avoid investing ...
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. ...
A penalty decomposition algorithm for the extended mean-variance-CVaR portfolio optimization problem
(
World Scientific
, 2023 , Article)
In this paper, we study mean-variance-Conditional Value-At-Risk (CVaR) portfolio optimization problem with short selling, cardinality constraint and transaction costs. To tackle its mixed-integer quadratic optimization ...
Structural influence of chromium substituted magnetite ferrofluids on the optical and antibacterial characteristics
(
Elsevier Ltd
, 2023 , Article)
A series of chromium substituted magnetite (CrxFe1?xFe2O4) ferrofluids with various concentrations ranging from x = 0-0.8 is reported in this work. Simple, cost effective and gentle co-precipitation method is followed for ...
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. ...
Genomic and Bioinformatics Approaches for Analysis of Genes Associated With Cancer Risks Following Exposure to Tobacco Smoking
(
Frontiers Media S.A.
, 2018 , Article Review)
Cancer is a significant health problem in the Middle East and global population. It is well established that there is a direct link between tobacco smoking and cancer, which will continue to pose a significant threat to ...
Effect of gamma irradiation on the microstructure and morphology of polyethylene oxide and polyvinyl alcohol blends
(
Trans Tech Publications
, 2010 , Conference Paper)
Thin films of a blend of 90, 75, 50 (wt/wt%) percentage of polyethylene oxide and polyvinyl alcohol were synthesized and irradiated with 5, 25, 50, 100 and 200 kGy. The presence of PVA leads to diffusion controlled mechanism ...
