The quality of coherent images computed from digital holography or heterodyne array data is sensitive to phase errors of the reference and/or object beams. A number of algorithms exist for correcting phase errors in or very near the hologram plane. In the case of phase errors introduced a nonnegligible distance away from hologram plane, the resulting imagery exhibits anisoplanatism. A feature o...
In recent years, it has become increasingly important to incorporate explicit dynamics in economic analysis. These two tools that mathematicians have developed, differential equations and optimal control theory, are probably the most basic for economists to analyze dynamic problems. In this paper I will consider the linear differential equations on the plane (phase diagram) and elements of nonl...
We have used GSAS package for Reitveld analysis of XRD data from H-Tc superconductor powder YBa2-xKxCu3O7-y (0<1) samples. The procedure of Potassium doping, x, results in some residual impurities in the sample and so few extra peaks in the XRD patterns would appeared. On the other hand, substituting K by Ba causes, to some extent, oxygen depletion and also the lowering of the Ba (K) plane po...
In this article, we have employed GSAS software to do Reitveld profile refinement on XRD patterns from H-Tc superconductor powder YBa2-xKxCu3O7-y (0<x,y<1) samples. Increasing the Potassium doping content of the sample, x, causes some changes in the XRD patterns such as creating new peaks and also deteriorating of goodness of the refinement, χ2. On the other hand, substituting of K instead of B...
The magnetic properties of 1 nm thick in-plane anisotropic Co ultrathin film on ZnO(0001) were investigated through successive 500 eV nitrogen-ion sputtering. Magneto-optical Faraday effects were used to observe the evolution of the ion-irradiated sample in longitudinal and perpendicular magnetic fields. The ferromagnetic phase of the initial in-plane anisotropic fcc β-Co phase transformation t...
a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
Introduction: Lower back pain is an orthopedic disease that affects up to 80% of people throughout their lifetime. It seems that the pattern of muscular activity is related to the components of earthquake photography and should be considered when evaluating back pain and its treatment. The aim of this study was to compare the three-dimensional lower limb joints stiffness during loading response...
