Effective preconditioners for large integral-equation problems
(2007)We consider effective preconditioning schemes for the iterative solution of integral-equation methods. For parallel implementations, the sparse approximate inverse or the iterative solution of the near-field system enables ... -
Experimental and theoretical investigations of electronic and atomic structure of si-nanocrystals formed in sapphire by ion implantation
(2008)The semiconductor nanocomposites based on Si nanocrystals in dielectric matrices attract a great amount of attention due to their ability for luminescence in visible and near-IR part of the electromagnetic spectrum. Si ... -
Fast and accurate algorithm for the computation of complex linear canonical transforms
(Optical Society of America, 2010-08-05)A fast and accurate algorithm is developed for the numerical computation of the family of complex linear canonical transforms (CLCTs), which represent the input-output relationship of complex quadratic-phase systems. ... -
In situ synthesis of biomolecule encapsulated gold-cross-linked poly(ethylene glycol) nanocomposite as biosensing platform: A model study
(Elsevier BV, 2010)In situ synthesis of poly(ethylene glycol) (PEG) hydrogels containing gold nanoparticles(AuNPs) and glucose oxidase (GOx) enzyme by photo-induced electron transfer process was reported here and applied in electrochemical ... -
Last PhD supervised by Professor Kouyoumjian: Extended UTD by Dr. Buyukdura
(2011)While he is a Professor Emeritus at Ohio State, Professor Kouyoumjian supervised a thesis work by Merih Buyukdura. They first derived a dyadic Green's function for a PEC wedge using spherical wave functions and employed ... -
Multiplier free co-difference matrix for image and video processing
(2009)In this paper, we propose a new image feature extraction method. We define a matrix called co-difference matrix for a given region. This matrix can be computed without performing any multiplications. The operator that we ... -
PO-MLFMA hybrid technique for the solution of electromagnetic scattering problems involving complex targets
(2007)The multilevel fast multipole algorithm (MLFMA) is a powerful tool for efficient and accurate solutions of electromagnetic scattering problems involving large and complicated structures. On the other hand, it is still ... -
Signal processing problems and algorithms in display side of 3DTV
(2006)Two important signal processing problems in the display side of a holographic 3DTV are the computation of the diffraction field of a 3D object from its abstract representation, and determination of the best display ... -
Synthesis of polybenzoxazine/clay nanocomposites by in situ thermal ring-opening polymerization using intercalated monomer
(2011)A new class of polybenzoxazine/montmorillonite (PBz/MMT) nanocomposites has been prepared by the in situ polymerization of the typical fluid benzoxazine monomer, 3-pentyl-5-ol-3,4-dihydro-1,3-benzoxazine, with intercalated ... -
Target detection in SAR images using codifference and directional filters
(2010)Target detection in SAR images using region covariance (RC) and codifference methods is shown to be accurate despite the high computational cost. The proposed method uses directional filters in order to decrease the search ...
