Factoring Integers Defined By Second And Third Order Recurrence Relations, Kirk Ocke

Theses

Factoring the first two-hundred and fifty Fibonacci numbers using just trial division would take an unreasonable amount of time. Instead the problem must be attacked using modern factorization algorithms. We look not only at the Fibonacci numbers, but also at factoring integers defined by other second and third order recurrence relations. Specifically we include the Fibonacci, Tribonacci and Lucas numbers. We have verified the known factorizations of first 382 Fibonacci numbers and the first 185 Lucas numbers, we also completely factored the first 311 Tribonacci numbers.

Applying A Genetic Algorithm To Improve The Lower Bounds Of Multi-Color Ramsey Numbers, Shardul Rao

Theses

Ramsey Theory studies conditions when a combinatorial object contains necessarily some smaller given objects. The role of Ramsey Numbers is to quantify some of the general existential theorems in Ramsey Theory. The objective of this thesis is to try to improve the lower bounds of Ramsey Numbers, in particular the bounds for multi-color graph Ramsey Numbers. Let Gi,G2,---,Gm be graphs on some n. R(G\,G2, ,Gm) denotes the m-color Ramsey number for graphs, avoiding G, in color i for 1 < i < m. Thus, to show R(G\, G2, . , Gm) > N, we need to find an edge coloring for a Kn graph using m colors (for N as large as possible) …

Teamwork In Genetic Programming, Michael Lalena

Theses

This thesis attempts to solve food collection problems using genetic programming. The genetic program will evolve programs that mimic the way ants can collect food and bring it back to a nest. There are two special factors in this genetic program that make the ants work together in order to solve the problem, as opposed to each ant acting on its own. First, there will be a stream in the environment that the ants must cross to get to the food. Although all ants have the same program, some must move into the water and die, building a bridge for …

Comparison Of An Incline Impact Table To Horizontal Impact Table As Used In Representing Pallet Marshaling, Amanda Hoffnung

Theses

This study compared horizontal impact tables to incline impact tables . The hypothesis is that both tables could achieve the same resultant impact. This study proved that this is possible. However, the initial speed at which the table is set, and the type of programmers used on each table effected the resultant impact. A number of trial runs with setting adjustments were necessary before a three mile-per-hour resultant impact was achieved. Once this setting was achieved to create the proper impact, both tables were within a 5% error when thirty consecutive impacts were produced on each table. Reproducibility was achieved …

A Study Of Package Drops In Global Distribution Environment, Donald Appleton

Theses

The focus of this study was to compile and interpret drop heights and drop frequencies data for small parcel packages moving through the Eastman Kodak Company global distribution network. The need for this study arose from the inclusion of drop height probability curves into Kodak's shipping tests for packaged product weighing less than 100 lb. Kodak packaging engineers suspected the drop heights included in the probability curves were too high in drop height and too many in frequency when compared to the actual distribution environment. The data for this study resulted from dozens of test shipments using dummy-load packages throughout …

Moisture Gain Of Biscuits In Hermetically-Sealed Packages Versus Non-Hermetically-Sealed Packages, Amran Alabakan

Theses

The objective of this study was to examine the affect of hermetic sealing on extending the shelf life of a biscuit product. Hermetically sealed packages were compared with non-hermetically-sealed packages received from the biscuit manufacturer. The package materials were the same so the only variable was the hermetic integrity of the package. A pressure test was conducted to determine the hermetic integrity of the package samples. The maximum moisture content that the biscuits gained before they were considered spoiled was then determined. Moisture gain of biscuit products kept in a 100% RH environment was monitored by recording the changes in …

Lived Body Architecture : An Argument For Lived Bodies In Architecture And An Exploration Of Women's Lived Bodies In Society, Sherri A. Scribner

Theses

This thesis is about architecture's current disregard for the lived body and about the lived bodily experiences of women in Western society. Although these seem to be two different themes, they are connected. Architecture disregards the lived body, but it can never escape it. Architects design buildings from their own lived experiences of the world and architectural theorists most often write about architecture from their experience of being in the buildings they discuss. But because architecture has been built and discussed predominantly by men, Western theories of architecture reflect mainly a male interpretation. I begin by analyzing the paradigms of …

Aluminum Nitride Films By Reactive Sputtering, Alvin Randolph

Theses

Aluminum nitride thin films (-1000 A) have been deposited on silicon substrate by re active sputtering using Al target in 1 : 1 Ar:N2 environment. The atomic force microscopy examination revealed continuous microcrystalline film structure. The Auger electron spectroscopic analysis shows the presence of oxygen in the films. The annealing at 850 C in nitrogen is found to cause recrystallinization and, by FTIR analysis, further oxidation of the films. The films can be characterized as lossy dielectrics with relative permittivity ~ 10, higher than the bulk value of 8.9. Annealing the films is found to reduce anion vacancies and improve …

A Study Utilizing Halftone Based Digital Proofing Systems In The Flexographic Printing Process, William Hanna

Theses

Contract proofing for printing has been traditionally done by press proofing. This is costly and wasteful, not just in terms of equipment and labor but also in terms of expendables. The advent of off-press proofing was greeted with some degree of uncertainty by the printing industry. With press proofing, the proof was literally a preview of what would happen on a press. The press proof, although often printed on a different press, generally used the same type of inks, plates and substrate that would characterize the final print. With offpress proofing, printers were comparing apples to oranges; instead of comparing …
