Algorithms for efficient vectorization of repeated sparse power system network computations
(IEEE, 1995)Standard sparsity-based algorithms used in power system appllcations need to be restructured for efficient vectorization due to the extremely short vectors processed. Further, intrinsic architectural features of vector ... -
Analysis of strain fields in silicon nanocrystals
(American Institute of Physics, 2009)Strain has a crucial effect on the optical and electronic properties of nanostructures. We calculate the atomistic strain distribution in silicon nanocrystals up to a diameter of 3.2 nm embedded in an amorphous silicon ... -
Detection of fungal damaged popcorn using image property covariance features
(Elsevier, 2012)Covariance-matrix-based features were applied to the detection of popcorn infected by a fungus that causes a symptom called " blue-eye" . This infection of popcorn kernels causes economic losses due to the kernels' poor ... -
Direct evidence for the instability and deactivation of mixed-oxide systems: influence of surface segregation and subsurface diffusion
(2011)In the current contribution, we provide a direct demonstration of the thermally induced surface structural transformations of an alkaline-earth oxide/transition metal oxide interface that is detrimental to the essential ... -
Integrable discrete systems on R and related dispersionless systems
(American Institute of Physics, 2008)A general framework for integrable discrete systems on ℝ, in particular, containing lattice soliton systems and their q-deformed analogs, is presented. The concept of regular grain structures on R, generated by discrete ... -
Maximum likelihood estimation of Gaussian mixture models using particle swarm optimization
(IEEE, 2010-08)We present solutions to two problems that prevent the effective use of population-based algorithms in clustering problems. The first solution presents a new representation for arbitrary covariance matrices that allows ... -
Photopatterning of PMMA films with gold nanoparticles: diffusion of AuCl4-ions
(2010)Photopatterning of poly(methyl methacrylate) (PMMA) films is performed by UV irradiation of the polymer films containing uniformly distributed AuCl 4 - ions. The process reduces the gold ions and leads to production of Au ... -
PO-MLFMA hybrid technique for the solution of electromagnetic scattering problems involving complex targets
(Institution of Engineering and Technology, 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
(IEEE, 2006-10)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 ...
