The present work aims to employ the photonic crystal fiber (PCF) for designing temperature and electric field sensors with intended manufacturing characteristics including: high sensitivity, repeatability and low cost by infiltrated with Nematic N-(4`-ethoxybenzylidene)-4-n-butylaniline liquid crystal(EBBA) liquid crystal. The novelty in this work is the use of EBBA that characterized by its ability to align by an external electric field.
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.
