“A.A. Cruz The University of Alabama in Huntsville Physics Department‚ 137 Madison Hall Huntsville‚ Al 35899‚ US April 2009.” Abstract In this study‚ a novel design of a Fabry-Perot band pass filter using as low and high index coating materials silicon dioxide (SiO2) and titanium dioxide (TiO2) is presented. Two high reflectance dielectric materials separated by a half wavelength “cavity” which is made up of SiO2 that allows light surrounding the central wavelength (550 nm) to

Five Stars Tools Case Five Star Tools is a small family owned firm that manufactures diamond coated cutting tools (chisels and saws) used by jewelers. In the past two years‚ the company has experienced growth and is at capacity in the coating and sharpening process. This has created a constraint‚ or bottleneck‚ that has caused the company to miss deadlines from several important customers. This case analysis seeks to provide solutions to the constraint problem. The following is a table showing

jewelers. Production involves three major processes. First‚ steel “blanks” (tools without the diamond coating) are cut to size. Second‚ the blanks are sent to a chemical bath that prepares the tools for the coating process. In the third major process‚ the blanks are coated with diamond chips in a proprietary process that simultaneously coats and sharpens the blade of each tool. Following the coating process‚ each tool is inspected and defects are repaired or scrapped.* In the past two years‚ the

Coating materials are usually made from polymeric material‚ but it can be also be made from non-polymeric materials. There are a wide range of techniques for microencapsulation. The techniques can be categorized into three processes. This includes‚ physical process‚ physico-chemical process and chemical process. Physical process includes‚ pan coating‚spinning disk‚ spray
