Computer Enhancement Of Real World Photographic Images Using Homomorphic And Linear Filtering, Nitin Sampat

Theses

Digital Image Processing techniques have become increasingly popular in the last few years. Conventional silver halide photography continues to be used by the large amateur market, but not without "imperfect" images. There is almost always a need for enhancement or subsequent improvement after the photograph is made. This study dealt with computer image enhancement of such "imperfect" photographs using homomorphic (non-linear) and linear frequency-domain digital filtering (on a VAX-11/785) and a comparison in effectiveness was determined, using a subjective criteria for image quality. It was found that, in general, linear filtering is to be the preferred method of choice when …

Frequency Characterization Of A Thin Linear Antenna Using Diakoptic Theory, Howard Harold Smith

Theses

A frequency dependent analytical expression for the input impedance of a thin wire antenna is obtained using diakoptic theory. In diakoptic theory the linear antenna is seperated into electrically short segments where each segment is treated as a two-port network. This approach eliminates the need for an integral equation formulation. An impedance matrix is found which characterizes coupling between all segments. By expanding the free space Green's function in a power series in wavenumber k each entry in the resultant impedance matrix is obtained as a function of frequency. Enforcement of the continuity of currents and equality of scalar potentials …

Information Retrieval In The Office For Effective Communication, Herbert Josef Schwoerer

Theses

The office worker of tomorrow, who is very likely to be an 'information-worker', will be heavily involved with communication of any kind. Effective communication, however, can only be guaranteed if the user is in control of information overload.

OIRS, the Office Information Retrieval System, designed and developed as a Master Thesis, is an approach to support the office worker in storing, maintaining, and retrieving textual information. By providing the user with a tool to impose a self-defined and self-maintained structure upon information or references to it, information overload, which is caused by lack of information about information, can be decreased. …

Characterization Of G.C.A. Wafertrac 9000 Using Kodak Micro Positive 820 Resist And Developer Zx-934, Janet Chapin Mcfarland

Theses

A static coating program and a spray/static development program were developed, for use on the Wafertrac 9000 using Kodak Micro Positive 820 resist and developer ZX-934 in order to minimize critical dimension shift and maximize process latitude. By maximizing process latitude, a greater tolerance for process and equipment errors can be achieved. Using the established process, 1.2µm resist lines were produced and critical dimension shift was minimized providing a process with wide process latitude for creating photoresist geometries with dimensions larger than 1.2µm.

Comparison Of Two Mtf Measurement Methods: Sine-Wave Vs Edge Gradient Analysis, John Cadou

Theses

A comparison of the sine-wave and edge gradient MTF measurement methods, on a photographic black and white film, was performed. A statistical test, a CMT acutance test, and a graphical comparison showed that there was no significant difference between the two measurement methods. This was true for the film processed to have large adjacency effects, as well as for the film processed to have no adjacency effects; however, the agreement was slightly better for the latter process. The research also showed that aligning the midpoints of the edge traces, normalizing the individual edge traces, and then averaging several edge traces …

A Recursive Fractal Design Generator For Dimensions Zero To Two Implemented Within A Two Dimensional Core Graphics Package, Elizabeth Lehmann

Theses

This thesis incorporates the technique developed by Benoit Mandelbrot to describe recursive fractals into an interactive graphics package based on the Core Graphics System (Core) produced by an ACM SIGGRAPH Committee (1977, 1979). The graphics package encompasses simple standard geometric shapes as well as the recursive fractals. To draw those fractals requires knowing both the basic shape or generator, and the points of recursion. These two pieces are acquired through the using of two windows which allow the generator and the points of recursion to be built. Once built, the fractal recursion level is chosen interactively on the main drawing. …

Effects Of Standardized Supplementary Activities And Reading Level On Spelling Achievement In First Grade, Lois A. Evans

Theses

Spelling programs in the primary grades often seem to lack internal continuity . Although students may receive appropriate activity lessons early in the school year, by the end of the year they are expected to master weekly lists of high frequency Dolch words in isolation . That is, the students are not given any predeveloped lessons that would allow them to use their spelling words in a meaningful context. It was the present researcher's contention that primary students would show higher levels of spelling achievement when the words were mastered through a standardized program of creative and functional writing exercises …

Application Of Manufacturing Resources Planning To Repetitive Manufacturing Environments, Irma L. Yuen

Theses

Most of the methodology for Manufacturing Systems has been devoted to Job Shops. Frequently the assumption has been made that, because Job Shops are the most complicated their methodology should fit Repetitive Manufacturing as well.

For years the Repetitive producers had been ignored as Production and Inventory Control Techniques were developed, implemented and refined to assist discrete Job Shops environments with Material Planning problems.

The application of modern Production and Inventory Control Techniques especially MRP II in the Repetitive Manufacturing Industries is receiving increasing attention from experts in the Production and Inventory Control field.

During the research for this Thesis …
