Two 10 and 20nm samples of Cu nano-cluster were grown on quartz substrates with a thickness of by electron beam deposition method. Nanolayers of titanium dioxide with a thickness of 300 nm were deposited on these Cu nano-cluster layers. For comparison، a layer of titanium dioxide with a thickness of 300 nm was also coated on quartz substrate. All coatings were conducted using electron-beam phys...

obtaining a seismic section with high temporal and spatial resolution was always one of the goals of seismic data processors and interpreters. accurate estimation of the thicknesses of thin beds is an important tool in this regard. the basic problem is that the wavelength of the signal must be similar in dimention to that of the bed thinness. if it is much longer than the bed thinness, the dete...

During recent years, the use of fiber-reinforced polymers (FRP) as a desirable alternative for improving the behavior of lateral resisting system are known. There are various factors influencing the quality of such kind of rehabilitation. This study aims to investigate the influence of geometric characteristics and arrangement of FRP layers on rehabilitating of concrete shear walls.  A few rein...

Statement: This study was conducted to determine the properties for thickness map of 11 retinal layers in fovea and 8 surrounding sectors. Retinal boundaries were determined automatically and the thickness results were compared between genders and for variety of ages. Abstract Purpose. This study was conducted to determine the thickness map of eleven retinal layers in normal subjects by spectra...
