The current in this thesis research deals with the plasma sputtering which was used to deposit single and triple layers ceramics on (cpTi) and ( Ti-6Al-4V) alloy. Also ,in this work the in vitro electrochemical tests  , formation of HAp by biomimetic process on the coated layers by the immersion in Simulated Body Fluid(SBF) at PH equal to 7.4 and room temperature was done . The single layer TiO 2and HAp , multi-layer consist of TiO2 and Al were deposited on cpTi and Ti-6Al-4Valloy, followed by the deposition of  third layer of HAp.

One of the main purposes of remote sensing satellite images is to interpret the observed data and classify features. Satellite image classification plays a major role in the extraction and interpretation of valuable information from massive satellite images.The primary purpose of this research is to classify multi-spectral Thematic Mapper satellite images using supervised classification. Unsupervised (RGB color model) and supervised classification (maximum likelihood method) is adopted to achieve the classification purpose.

           This work investigates the joining between graphite and stainless steel grade (410), by using active filler metal paste. Brazing technique was chosen because it is efficient, verstile, fast and economical.High purity of metal powder of  silver, copper  and titanium in different concentrations were mixed carefully to prepare a filler paste.
