Photonic Band gap in the Triangular Lattice of Bose-Einstein-Condensate Vortices
(2007)
We investigate the photonic bands of an atomic Bose-Einstein condensate with a triangular vortex lattice. Index contrast between the vortex cores and the bulk of the condensate is achieved through the enhancement of the ...
Dynamical Instability of a Two Component Bose-Einstein Condensate in an Optical Lattice
(2006)
We investigate the dynamical instability for a two component Bose-Einstein Condensate (BEC) in an optical lattice. We assume that the two components are in sinusoidal potentials with the same period but different phases. ...
Coulomb crystallites from harmonically confined charged bosons in two dimensions
(Iop Publishing Ltd, 2008)
We exploit rotational-symmetry breaking in the one-body density to examine the formation of structures in systems of N strongly coupled charged bosons with logarithmic repulsions inside isotropic two-dimensional harmonic ...
Importance of biomass energy as alternative to other sources in Turkey
(Elsevier Sci Ltd, 2009)
Energy plays a vital role in socio-economic development and raising standards of human beings. Turkey is a rapidly growing country; both its population and economy are expanding each year so its energy demand increases ...
PERFORMANCE ASSESSMENT OF A COMBINED SOLAR AND WIND SYSTEM
(King Fahd Univ Petroleum Minerals, 2009)
This paper deals with a feasibility study of a solar and wind hybrid system for highway energy requirements. The paper describes the modeling of two emerging electricity systems based on renewable energy: photovoltaic and ...
Vakum ve Modifiye Atmosferde Paketlemenin Balıkların Raf Ömrü Üzerine Etkisi
(2008-07)
Beslenme açısından değerli bir gıda olan balık, tüketilinceye kadar uygun koşullarda tutulmadığı takdirde hızlı bir şekilde bozulabilmekte ve sağlık için tehlikeli hale gelebilmektedir. Balıkların raf ömürleri atmosferik ...
Classifying 8-bit to 8-bit S-boxes based on power mappings from the point of DDT and LAT distributions
(Springer-Verlag Berlin, 2008)
S-boxes are vital elements in the design of symmetric ciphers. To date, the techniques for the construction of S-boxes have included pseudo-random generation, finite field inversion, power mappings and heuristic techniques. ...
The role of confinement and shape on the binding energy of an electron in a quantum dot
(Elsevier Science Bv, 2008)
The impurity ground state binding energy in cubic and cylindrical GaAs/AlAs quantum dots has been calculated using a variational procedure within the effective mass approximation. We exploit the impurity ground state energy ...
The energy spectrum for an electron in quantum well wires with different shapes under the electric and magnetic fields
(Elsevier Science Bv, 2008)
The ground-state energies and wave functions for an electron in quantum well-wires (QWWs) with different shapes under the electric and magnetic fields are directly calculated using the finite difference method. It is shown ...
Electric and magnetic field effects on the binding energy of a hydrogenic impurity in quantum well wires with different shapes
(Academic Press Ltd- Elsevier Science Ltd, 2008)
In this work, we directly calculate the ground state energies for an electron in quantum well wires (QWWs) with different shapes in the presence of applied electric and magnetic fields using the finite difference method. ...
