Image Processing Techniques And Implementations In Software For Use With A Ccd Camera, Clarence Franklin Jr.
Image Processing Techniques And Implementations In Software For Use With A Ccd Camera, Clarence Franklin Jr.
Opportunities for Undergraduate Research Experience Program (OURE)
The concept of image processing is used whenever there is a reference to digital images. By random and natural errors introduced into the image during collection and transmission, the images are distorted. Image processing techniques are used to eliminate these error before viewing of the images. For this experiment, the images provided by the ST-6 CCD Camera System will be used in the development and implementation of image processing techniques into a software package.

Designing A New Programming Methodology For Optimizing Array Accesses In Complex Scientific Problems, Larry Coffin
Opportunities for Undergraduate Research Experience Program (OURE)
Many problems of interest to scientists and engineers, such as fluid flow and stress analysis, require the solution of complex PDEs. Often the solution requires discretizing the physical domain into a mesh or grid then stepping from a given initial state towards some final state using small incremental time steps. Grid sizes can reach several thousand to hundreds of thousands of elements and the number of time steps required to solve the problem can vary from several thousand to tens of thousands or more. Traditional programming techniques are unable to take advantage of the non-random grid access patterns and generally …
Relaxation Technique For The Fitting Of Numerical Data, Michael J. Lehmann
Relaxation Technique For The Fitting Of Numerical Data, Michael J. Lehmann
Opportunities for Undergraduate Research Experience Program (OURE)
Data, in particular that generated through successive computer approximations, may not always follow the smooth curve it is suppose to. Approximations in input data, round off error, and estimations made in the mathematical formulas, are just some of the things that could cause this problem. In any respect, this data must somehow be smoothed or fitted for publication. One way of fitting such data sets is the relaxation method. This method does not rely on the data conforming to a specific mathematical shape, as opposed to other programs that require the data to be fitable by some mathematically generated curve. …

Ccd Photometry At The Umr Observatory, Christopher P. Smith
Opportunities for Undergraduate Research Experience Program (OURE)
During the summer of 1993 a number of advances at the University of Missouri-Rolla’s observatory have taken place. These advances range from cleaning the mirrors and polar aligning the 16-inch Cassegrain telescope to the acquisition of needed supporting material. A program for observing variable stars, implementing the newly acquired CCD1R image reduction program, searching galaxies for supernova, and the possibility of adding low resolution stellar spectroscopy to our research capabilities will be discussed. This manual will discuss how to implement the new CCDIR program.
The Synthesis And Characterization Of Poly (1,1'-Divinyl-2,2’-Biimidazole), Timothy S. Evenson
The Synthesis And Characterization Of Poly (1,1'-Divinyl-2,2’-Biimidazole), Timothy S. Evenson
Opportunities for Undergraduate Research Experience Program (OURE)
The monomer 1,1 ,-divinyl-2,2’-biimidazole was prepared using a previously published procedure (1). The new divinyl biimidazole polymer was then synthesized from this monomer. The polymer was characterized by infrared and ultraviolet-visible spectroscopy. Nuclear magnetic resonance confirms the structure of the polymer. Also, gel permeation chromatography was used to determine molecular weight, while differential scanning calorimetry was used to determine the glass transition temperature and crystalline melting point of the polymer.
Sporomorphs And Palynological Interpretations Of Lower Oligocene Strata From The Eastern Gulf Coast, U.S.A., Lisa M. Reeves
Sporomorphs And Palynological Interpretations Of Lower Oligocene Strata From The Eastern Gulf Coast, U.S.A., Lisa M. Reeves
Opportunities for Undergraduate Research Experience Program (OURE)
The Vicksburg Group in the eastern Gulf Coast of the United States belongs to one of the most complete and continuous Paleogene strata in the world. Previous studies in this region have neglected the rich palynomorph assemblages of the Lower Oligocene units of the Vicksburg Group. Four samples from Wayne County Mississippi were analyzed for palynological information on the Vicksburg Group. The initial objective of the study was to understand the principles of palynology and the basis for sporomorph identification. A minimum of 300 specimens were counted per slide to determine the distribution of sporomorphs in the sediments. Two hundred …

Solar Spectroscopy Using 50 Meters Of Fiber Optic Cable And Ccd Camera, Christopher P. Smith
Opportunities for Undergraduate Research Experience Program (OURE)
Measurements of the variation of the Can K line profile using very modest equipment is discussed. The equipment used included a Spex 0.75 meter spectrometer, a Santa Barbara Instrument Group 16 bit ST-6 Charge Coupled Device (CCD) camera, fiber optic cable, and a 10-inch Cassegrain telescope. Observations were made in both regions of little or no solar activity as well as in regions of high solar activity (sunspots). A roughly 8% increase in Ca II K emission was observed over a sunspot. The combination of the unique observing apparatus and the intensity resolution of the CCD camera was essential for …
Macrocyclic Antibiotics As A New Class Of Chiral Selectors For Liquid Chromatography, Christine Bagwill
Macrocyclic Antibiotics As A New Class Of Chiral Selectors For Liquid Chromatography, Christine Bagwill
Opportunities for Undergraduate Research Experience Program (OURE)
In the field of chromatographic separations, the need for new chiral stationary phases is always in demand. Many stationary phases already exist, some of the more popular being cyclodextrin or protein based phases. During this research, a new class of chiral selectors were discovered and evaluated for chiral recognition. Vancomycin, thiostrepton, and rifamycin B all belong to the macrocyclic antibiotic family. Not only can this new class of chiral selectors be used to resolve compounds that cannot be separated on any other column, but it is also more stable and has much greater capacity than protein based columns.
Modified Recycled Glass As An Additive In Coatings Applications, Garth D. Brown
Modified Recycled Glass As An Additive In Coatings Applications, Garth D. Brown
Opportunities for Undergraduate Research Experience Program (OURE)
The feasibility of using chemically modified, finely pulverized recycled glass as an additive in coatings was investigated. The ground glass was added as partial replacement for the conventional pigment titanium dioxide (TiO2). The loss of TiO2 pigment was compensated with an optical brightening agent (OB agents). OB agents can help contribute to a coating’s hiding capacity by absorbing light in the UV range, releasing light of a lower energy in the visible spectrum. Glass supplemented coatings were formulated and common paint tests were performed. The glass changed the optical and physical properties of the coating formulations. The …

Synthesis Evaluation Of New High Performance Polymer Systems Involving Tetrachlorohydroquinone, Jason A. Giles
Opportunities for Undergraduate Research Experience Program (OURE)
New high performance transparent polymers are in demand in the aerospace and automotive industries to replace current glass and composite systems. Tetrachlorohydroquinone (TCHQ) was used as the base monomer for various copolymer formulations. Different acid chloride monomers lead to polyester formation with TCHQ. Polycarbonates were formed with triphosgene and diethyl carbonate. This base monomer added rigidity, transparency, and high temperature resistance, however, resulting polymers were brittle and difficult to process. Polymers were characterized by IR and DSC.

Development Of A Recycled Glass Corrosion Inhibitor For Surface Coatings And Concrete Applications, Theresa Pierce
Opportunities for Undergraduate Research Experience Program (OURE)
This research was performed to study the possibility of attaching a metal corrosion inhibitor to recycled glass powder. Such a material would be useful as a corrosion inhibitor component for metal substrate coatings. The major experiments performed were first to produce a metal corrosion inhibitor (Irgacor 153)/silane coupling agent (3-(chloropropyl)trimethoxysilane) adduct and secondly to attach this corrosion inhibitor/silane adduct onto the surface of glass. To test feasibility, qualitative corrosion tests were performed using steel wool as the corroding metal and a number of product samples.
