Monitoring the Built-up Area Transformation Using Urban Index and Normalized Difference Built-up Index Analysis
Makassar is one of the metropolitan cities located in Indonesia which recently experiences massive an increased construction because of population growth. Mapping the spatial distribution and development of the built-up region is the best method that can use as an indicator to set the urban planning policy. The purpose of this study is to identify changes in land use and density in Makassar Cit...
متن کاملnumerical simulation of orthogonal cutting process and determination of built up layer thickness
the built up layer thickness in secondary deformation zone is one of the important parameters in metal cutting process. the built up layer (bul) is formed in second deformation zone near the tool-chip interface in the back of the chip. this parameter influences the tool life and machined surface quality. this bul should not be confused with the built up edge (bue). the deformation of the bul in...
متن کاملAntigen-antibody Reactions between Layers Adsorbed on Built up Stearate Films
By adsorbing antigens and antibodies on barium stearate multilayers immunological reactions at surfaces have been studied. Pneumococcus polysaccharide specific antibody systems using purified antibodies from both horse and rabbit sera were investigated. The polysaccharides failed to show visible adsorption, but by alternate treatment with antibody and polysaccharide several layers of antibody c...
متن کاملImpedance of nanometer thickness ferromagnetic Co40Fe40B20 films
Nanocrystalline Co40Fe40B20 films, with film thickness tf = 100 nm, were deposited on glass substrates by the magnetron sputtering method at room temperature. During the film deposition period, a dc magnetic field, h = 40 Oe, was applied to introduce an easy axis for each film sample: one with h||L and the other with h||w, where L and w are the length and width of the film. Ferromagnetic resona...
متن کاملThe Effect of thickness parameter and Fluorine Dopant on Photocatalytic performance of TiO2 thin films
In this study, Pure and doped titania sols with Fluorine (F/Ti:0.06) dopant, were prepared by sol-gel method and Ammonium Fluoride(NH4F) as the precursor. They were deposited on glass substrates (soda lime) in a certain(optimum) nanometric thickness by the dip coating method. Coated samples were dried and calcined under the specific rate. Phase composition and optical properties of coatings wer...
