Dosimetric Aspects of Poly(ethylene- g - maleic anhydride)
Abstract: Electron spin resonance (ESR) spectroscopy is considered to be finger print technique to identify chemical structures of irradiated polymers. To prove this, ESR spectra of unirradiated and irradiated maleic anhydride grafted poly ethylene (MANPE)are recorded under different conditions. The ESR spectra show multiplehyperfine lines with latent structure corresponding to macro radicals . Radiation dose dependency on chemical structure of MANPE has been investigated by recording ESR spectra at various radiation …

The Effect of using Grease on the Surface Roughness of Aluminum 1100 Sheet during the Single Point Incremental Forming Process
Abstract: Incremental forming is a sheet metal forming technique in which a uniform sheet is plastically deformed through the progressive action of a rounded tool. The movement of the tool is governed by a CNC machine. By this way the tool locally deforms the sheet through pure stretching deformation. In this research incremental forming experiments were carried out on Aluminum 1100 sheets to form a cone shape. Roughness was studied by …

Understanding of optical power in semiconductor based SOI Structure at the signal 1550 nm
Abstract: A silicon-on-insulator (SOI) structure consists of a single crystalline silicon layer separated from the bulk substrate by a thin insulator layer. The insulator in SOI wafers is usually always a thermal silicon oxide (SiO2) layer, with a silicon wafer as the substrate. The silicon sheet can be very thin (50 nm for fully depleted transistors) or tens of micrometres thick, depending on the application. Similarly, the thickness of buried oxide …
