The Abel Inversion Of Noisy Data Using Discrete Integral Transforms, Subramania I. Sudharsanan
The Abel Inversion Of Noisy Data Using Discrete Integral Transforms, Subramania I. Sudharsanan
Masters Theses
The determination of a radially symmetric two-dimensional function from its one dimensional projection is known as Abel inversion. This finds applications in several fields of engineering and science including astronomy, image processing, plasma diagnostics and optics. One radial slice of the function, which completely specifies the two-dimensional function, is the inverse Hankel transform of the Fourier Transform of the projection. With the projection data available as a discrete signal, the Abel inversion can be performed using the discrete Fourier transform and the inverse Hankel transform. The existing techniques to compute inverse Hankel transforms are discussed and a modification to one …

Production Test Station Networking And Collection Of Test Results, Dennis Wallace Matheson
Masters Theses
This thesis describes the installation of a network for all of the final test stations at the Industrial Systems Division of Texas Instruments in Johnson City, Tennessee. Once the network was installed, the project focused on the automatic collection of the test parameters for a centrallized database. The database was used to generate statistical data to determine if the manufacturing process were in control. If the process were not in control, then appropriate action was taken to prevent the particular unit from being tested. This provided a accurate and real-time analysis of how the manufacturing process was performing. Also, the …
