Sql/Ds, Ingres And Indexes: A Comparative Study Of The Use Of Indexes In Two Database Systems, Karen L. Bourn

Masters Theses

Many people in data processing desire to know more about the performance of relational databases. Little information about performance exists in the product or public literature. The purpose of this study is to compare one aspect of the performance of relational databases. The aspect explored is the indexing of tables in a relational database. This paper compares the use of indexing in two relational databases, SQL/DS (Ver. 2, Rel. 1) and INGRES (Rel. 5.0/0.6). Queries were created and executed on tables in both databases, first without an index and then with several different indexes.

Masters Theses

This thesis traces the development of a neural net model which will solve the assignment problem. In addition, the neural net model was compared for optimal performance with four other algorithms: two greedy methods and two well-known solutions, Vogel's Approximation Method (VAM) and the Hungarian method. Assignments were made to randomly generated problems using each method and the results were compared.

The findings from this testing indicated that: (a) the assignments selected by the neural net model were closer to optimal than the two greedy methods and VAM, and (b) the assignments selected by the neural net were not optimal. …

Perceptual Effects Of Perturbation And Additive Noise, Richard E. Nero

Masters Theses

This study investigated the perceptual effects of varying glottal waveshape perturbation, duty cycle perturbation, jitter, signal-to-noise ratio perturbation, and shimmer at three levels of perceived magnitude (high, medium, and low). Voice signals were synthesized using a modified version of Klatt's (1980) formant synthesizer. Listeners rated signal dysphonia using an A-B dissimilarity procedure. Multidimensional scaling analysis suggested that signals judged low in magnitude of dysphonia were perceived to be most similar. Medium-level and high-level magnitude signals were judged to be respectively less similar. Signals varying in duty cycle and fundamental frequency perturbation were perceived to be very similar while those signals …

Simulation Of Bromide Transport In A Layered Aquifer Using Two-Dimensional And Three-Dimensional Computer Models, Kathleen Michelle Hewitt

Masters Theses

Simulation of a two-well tracer test at a site near Mobile, Alabama was performed and compared with the experimental breakthrough curve. The models used to simulate the test results were the three-dimensional USGS code HST3D and the two-dimensional USGS code MOC. The results of the three-dimensional model were also compared with the results of the two-dimensional model.

The three-dimensional model HST3D predicted the measured breakthrough curve accurately with the exception of early arrival times of the tracer in the withdrawal well. The two-dimensional model MOC did not accurately predict the bromide concentration in the withdrawal well during the two-well test. …

Analogical Reasoning Of Elderly Adults Using Three Modalities: Words, Pictures, And Figures, Judy L. Rau

Masters Theses

This study examined the analogical processing skills of elderly adults. Forty-seven subjects (ages 65-90) completed analogy tasks presented in three modalities: words, pictures, and geometric figures (90 total). The subjects for this study were elderly adults living independently in a federally subsidized apartment building. The subjects used in this study possessed characteristics similar to the "typical" American adult. Results indicated that performance does not vary significantly with age in the word and picture modalities. Significant (p < .05) negative relationships were found between performance on the geometric figure analogies and increased age and between overall performance and increased age. Significant (p < .05) positive relationships were found between education and performance on each of the three modalities as well as between education and overall performance.

Masters Theses

The accountability of the nation’s schools is an area of great public concern. A useful tool that a school district may use in becoming more accountable to the public is a parent opinion inventory. The inventory may serve as one step in the process of bridging the gap between public expectations of the school district and its actual performance. This study measured the opinions of fifty-seven parents about the performance of the Central City school district. The opinions were determined by a fifty-one item inventory issued to parents in grades kindergarten through grade eight. Recommendations, based upon inventory results, were …

Indirect Photometric Chromatography Of Inorganic And Organic Anions Using Benzoate As An Eluent, Shahab A. Shamsi

Masters Theses

For many years the determination of common inorganic and organic anions was hindered by the lack of adequately sensitive analytical techniques. The determination of these anions was laborious and time consuming (e.g. titration, precipitaion, gravimetric analysis etc.). Because of the development of high-performance liquid chromatography, the anion exchange separation of simple inorganic and organic anions is now possible. Now, there are a broad and ever-increasing array of chromatographic methods supplanting these older chemical methods. However, detection is still a problem, but indirect detection provides a practical route for the detection of non-chromophoric inorganic and organic anions.

This dissertation describes the …

Calculation Of Electron Scattering For 4He In A Continuum Shell Model, Ming Yu

Masters Theses

Calculations for the electroexcitation of the ⁴He, O+ state have been performed within the context of recoil corrected continuum shell model. Approximations previously employed for inelastic scattering with the recoil corrected continuum shell model are eliminated in the work. The O+ state exhausts only 10% of the energy weighted sum rule and previous shell model calculations for the excitation of this state produce about ten times too much strength. This difficulty is alleviated by the use translationally invariant wave functions and the application of continuum boundary conditions for this particle unbound state. The structure of the O+ state is …

Relativistic And Non-Relativistic Nuclear Charge Form Factors, Tao Wang

Masters Theses

This thesis presents an examination that the two nuclear charge form factors, relativistic and non-relativistic, are equivalent approximately in an appreciable range. The relativistic one is contributed by both vector charge density and tensor charge density. And the non-relativistic charge form factor is contributed by the nuclear densities from experimental electron scattering cross section, these densities are fundamental to much of nuclear structure physics.

The Dirac equation is used to calculate the vector charge density and tensor density, because the charge density from the analysis of the experimental data may be compared with proton charge densities obtained from various models …
