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.

A Computer Simulation and Application of PV cell on DC-DC Converter

     Photovoltaic system generates electricity by the direct conversion of the sun's energy and it is a modular system because it is built out of several pieces of elements. The theoretical studies of PV and modeling techniques using equivalent electric circuits carried out and the characteristics of PV cell have been investigated.

Multi-Temporal Analysis of Environmental Changes in Marsh Region by Landsat Images

    Iraqi marshes were considered the largest wetland in the Middle East and characterized by varied environment (such as river, lakes and vegetation covers). During the last decades the Iraqi marshes subjected to many artificial and natural changes. These changes have impacts on its ecosystem (land cover, vegetation and aquatic environment).The aim of this study is detect environmental changes in the Iraqi

Effect of Band Ratios and Indices on Classification Accuracy of Multispectral Satellite Images

      Multispectral satellite images are holding whole information about the area under investigation. Many of digital processing techniques are used to extract most of the possible information from these images, such these techniques are spectral band ratios, Tasseled Cap transformation and Principle Component Analysis (PCA).

Radioactive Detection On the Blood Samples of Cancer Patients Diseases by Using CR-39 Detector and its Effect on Cytogenetic

The aim of this project is to measure the uranium concentrations in blood samples taken from control group and patient group taken from different governorates of Iraq  , and measure the effect of Uranium in human chromosomes and cellular division, therefore this study was designed to investigate the effects of Uranium on the human through cytogenetic studies.The first part contains the determination of Uranium concentration in blood samples using CR – 39 track detector.The nuclear reaction used a source of nuclear fission fragments is (n, f) obtained by the bombardment of U – 235

DESIGN OF ION MIRROR AS AN ABERRATION CORRECTOR USING BOUNDARY VALUES METHOD

      The idea of using  an electron mirror to correct the chromatic and spherical aberration of around lens dates back more than half of century.Extensive studies of electrons mirrors have been performed by the Kelman, Rempfer, Shao, and Rose and co-workers [Barnett and Nixon 1966].

APPLICATIONS OF COUPLED CLUSTER MODEL IN LIGHT NUCLEI

One of the recent discoveres in nuclear Physics is the existance of Halo nuclei .Therefore, halo nuclei are very weakly-bound exotic states of nuclear matter in which the outer one or two valence nucleons (usually neutrons), and a nuclear core with normal nuclear density is surrounded by a region of dulite nuclear matter, referred to as the neutron halo. Such nuclei occur from light to heavy masses and have been the subject of a alarge number of theoretical studies to try and understand them.
