A Computational Program to Determine Some of Crystal Structure Specifications

  Computational program "Crystal-2" in Visual Basic 6.0 was designed and applied to identify the  specification for three crystal structures includes the lattice parameters (a, b, c), the axial angles (α, β, γ), the Filling Factor(FF) foe CdS, the Average Grain Size (AGS) for CdS, and the Elastic Strain (ε) for CdS and CdTe.This program will give us a complete description on crystal structure for three crystal structures material by inserting a data which include the values of Miller indices (hkl), the diffracted angle (2θ) from ASTM data for cadmium sulfide, beryllium and compare the calcu

Image Restoration Using Adaptive Nonlinear Techniques

Image restoration is the process of finding an approximation to the degradation process and find appropriate inverse process to estimate the original image.An iterative restoration technique(Tikhonov method) was adapted.The adapted filter was designed for restoring RGB satellite images that are blurred with space-invariant point spread function, Gaussian function, and corrupted with additive noise, and salt & pepper noise.Different degradation parameters, i.e.
