A low cost alternative for satellites-tethered ultra-high altitude balloons
(2011)
Geostationary and geosynchronous satellites have a wide area of application in present day technology. The main drawback for the wider usage of such satellites is their high cost of launching into their orbit. As alternatives ...
Peripheral and Structural Effects on the Band Gap of Acceptor-Donor Type Conducting Polymers Containing Pendant Bisfulleroid Groups
(Amer Chemical Soc, 2011)
In this computational study, the band gap energy of an acceptor donor type conducting polymer consisting of terthiophene repeating units with a fused bisfulleroid group was estimated by extrapolating excitation energies ...
Second-order wave diffraction by horizontal rectangular barriers
(2011)
A complete second-order analytical solution for the nonlinear diffraction of waves by 2-D rectangular cylinders fixed at the free surface of finite-depth waters is presented. As a sequel to a previous linear treatment of ...
Condensation of two-dimensional harmonically confined bosons with Bessel-type interactions
(Amer Physical Soc, 2011)
We study the ground-state configurations of few interacting bosons confined in two dimensions by anisotropic harmonic potentials. By means of variational calculations, including correlation effects, we show that the ...
Anderson localization in optical lattices with speckle disorder
(Amer Physical Soc, 2011)
We study the localization properties of noninteracting waves propagating in a speckle-like potential superposed on a one-dimensional lattice. Using a combined decimation-renormalization procedure, we estimate the localization ...
Breast Cancer Classification by Using Support Vector Machines with Reduced Dimension
(Croatian Society Electronics Marine, 2011)
Correct and timely diagnosis of diseases is an essential matter in medical field. Limited human capability and limitations decrease the rate of correct diagnosis. Machine learning algorithms such as support vector machine ...
Modeling of twin-turbine systems with vertical axis tidal current turbine: Part II-torque fluctuation
(Pergamon-Elsevier Science Ltd, 2011)
We recently showed the advantage of using a numerical system to extract energy from tidal currents by developing a new twin-turbine model (Li and Calisal, 2010a). Encouraged by this result, we decided to use this model to ...
Comparison of Additive Protective Layer On the Cylinder Liner Surface Using Diesel Engine and Pin-On-Plate Test Rigs
(Scibulcom Ltd, 2011)
In this research, the layer formation of additives on the surface of cylinder liner (single cylinder Diesel engine liner operated 22 h) was examined by using binocular, optical, scanning electron microscope and energy ...
Effect of Additive Level On the Surface of Diesel Engine Cylinder Liner
(Scibulcom Ltd, 2011)
In this research the surface of the cylinder liner was examined from metallurgical standpoints, using specimens cut from real engine component (single cylinder diesel engine liner operated 22 h), in order to identify the ...
A numerical study on squat of a wigley hull
(2011)
A numerical study is conducted to calculate the squat for a wigley hull. An approach based on slender body theory is used to convert the three dimensional ship problem into a series of two dimensional problems in cross ...
