Many scientific applications including molecular dynamics (MD) require a fast fourier transform (FFT). As the number of processors for high performance computer increases this transform has to be parallelized to larger number of processors to remove it as a bottleneck for the parallelization. This requires the decomposition to be changed from 1D to 2D. Such a 2D decomposed 3D FFT was implemente...

We introduce a universal method to optically induce multiperiodic photonic complex superstructures bearing two-dimensional (2D) refractive index modulations over several centimeters of elongation. These superstructures result from the accomplished superposition of 2D fundamental periodic structures. To find the specific sets of fundamentals, we combine particular spatial frequencies of the resp...

: In this study we fabricated Zinc Oxide thin film by sol-gel dip coating method on glass substrate. X-ray reflectivity (XRR) and its optimization have been used for characterization and extracting physical parameters of the film. Genetic Algorithm (GA) has been applied for this optimization process. Independent information was exploited from Fourier transform of Fresnel reflectivity normalized...

In order to study the effects of extensional viscosities on turbulent drag reduction, experimental studies using two-dimensional turbulence have been made. Anisotropic structures and variations of energy transfer induced by polymers are considered. Polyethyleneoxide and hydroxypropyl cellulose having different flexibility, which is due to different characteristics of extensional viscosity, are ...

We give a Bäcklund transformation connecting a generic 2D dilaton gravity theory to a generally covariant free field theory. This transformation provides an explicit canonical transformation relating both theories.

We calculate the local Fourier transformations for a class of Q l -sheaves. In particular, we verify a conjecture of Laumon and Malgrange ([L] 2.6.3).
