This creative project investigates a method for translating a run-length encoded data file of letterforms into bit mapped images. Each letterform is broken (cracked) into primitive strokes. Each primitive stroke is represented by equally spaced runlength spline points within a 72 unit counting system. The strokes are ordered from left to right, allowing a direct scan-line conversion using an on-off character fill. Most commercial letterforms are stored in an outline format. Outline letterfomrs must be converted to vector edges, and then quick sorted into two dimensional arrays of edges for scan-line conversion (no overlapping outlines are allowed). The author's method stores primitives in a left to right ordered format that eliminates the sorting routine.In order to display the letterforms as a body of text, an interpreted description language was developed. The language command structure is embedded in the text file and interpreted at run time. The language controlls the sizing and placement of letterforms at five levels. The page attributes controlls the placement of page margins, column margins, windows, headers, footers, etc. The Paragraph attributes controlles first word indents, paragraph indents, widow lines, etc. The line attributes controlles the text line length, inter word and character spacing, line leading, additional line indents, type of line justification and hyphenation, etc. No attributes were established at the word level. The character attributes controlles the type size, type style, degree of slant (poor man's italic), expansion or contraction, etc.Ball State UniversityMuncie, IN 47306

The purpose of this study was to optimize and investigate crown ether analysis by using a mass spectrometer equipped with a direct insertion solids probe. The typical aliphatic and aromatic crowm ethers, 18-crown-6 and dibenzo-18-crown-6 were chosen for the study. The crown ether samples were prepared by miximg with the reagents (some inorganic and organic salts and glycine) or being supported on the support materials (diatomite and glass supports) in a 1:10 ratio by weight as the samples for testing. The pure crown ethers and their mixtures were tested by the programmed temperature direct insertion probe mass spectrometer. The effects of the reagents and support materials on the peak maximum temperature (Tm) and the spectra of the crown ethers were studied. The results Tm of the crown ethers to increase significantly, and glycine and ammonium salts interfered the spectra of the crown ethers. The effect of sample size and "concentration" on Tm of the crowns also was investigated. The bigger sample size caused the Tm to be higher. No significant effect of the "concentration" on Tm was observed. It was concluded that tha smaller sample size provided better spectra with less interfererences and that some thermally stable reagents or support materials could be used to facilitate the sampling of crown ethers. More detailed study of the effects of iodides on Tm was recommended. In addition, more detailed investigation of the approach of using a CI source without reagent gases is needed. Switching to the CI configuration appears to be a simple and effective method for providing complementary information about the molecules.Ball State UniversityMuncie, IN 47306

This thesis describes the development of computer programs and the theory for the calculations of stopping power and nuclear reaction kinematics. The nuclear reaction kinematics program computes position and nonrelativistic energy data as well as center-of-mass solid angle transformations and information on detector resolution for nuclear reactions and elastic scattering experiments involving two-body final states. The stopping power program calculates stopping power (an index of the charged particle energy absorption properties of a material) of elemental absorbers for protons, deuterons, tritons, He3, and alpha particles from minimal input data. The calculated stopping powers are accurate to within one per cent over the nonrelativistic energy range of 2 to 12 Mev.Ball State UniversityMuncie, IN 47306
