An Investigation Of The Adequacy Of Air Force Regulations Guiding The Development And Procurement Of Software User Manuals, Amy M. Baines

Theses and Dissertations

As the Air Force increases its emphasis on controlling the cost and quality of software development, it's important to ensure that the documentation to support that software is also quality controlled. This research evaluated the adequacy of current regulations by comparing the process for developing Air Force software manuals with the process for developing similar types of user manuals, both within and outside of the Air Force. A comparison to the regulations guiding the development of Air Force Technical Orders revealed that the requirements for software manuals are unclear, dispersed through numerous regulations, and at times contradictory from one regulation …

Collisional Dynamics Of The B3Π(O+) State Of Bromine Of Monofluoride, David W. Melton

Theses and Dissertations

When Bromine is combined with flourine atoms and discharged oxygen in a flow tube is produced in a highly non thermal distribution peaking at v'=3. The emission was linearly dependent on the concentration. The observed dependence of the BrF(B) emission on Bromine and atomic oxygen is inconsistent with a steady state prediction of a sequential excitation mechanism, where BrF(X) is excited by successive collisions with singlet oxygen. The experimental data are consistent with a three body mechanism involving Br and F atoms. Electronic quenching of BrF(B) by a number of collision partners (Br₂, CO₂, O_{2 …}

The Child Witness: The Effects Of Videotaped Versus Live Testimony On Juror Perceptions Of Guilt., Sharon Kaye Hagen

Theses and Dissertations

A total of 192 jury-qualified subjects participated in this study which compared the effects of a child's videotaped deposition on juror's perceptions of a defendant's guilt to live in-court testimony. A three hour trial, videotaped from a simulated case of child physical use being conducted for the Trial Advocacy Class of the University of North Dakota Law school, was shown to all subjects. A separate deposition of the child's testimony, identical to the live testimony, was also videotaped and shown to half the subjects. Eight juries viewed the videotapes of the trial with the child testifying on the witness stand …

The Use Of Transition Metal Complexes For The Construction Of Unusual Metal-Modified Phosphorus Linkages Between Nucleosides., Theresa Jo Schmaltz

Theses and Dissertations

Oligonucleotides based on methyl phosphonate linkages between nucleoside units have been of particular interest as anti-sense molecules for inhibiting mRNA function. The focus of our research has been on the development of new construction techniques for anti-sense oligonucleotides. Specifically we have been investigating new methods for generating iron and cobalt-modified linkages in oligonucleotides during the course of automated synthesis.We have found that (dicarbonyl)($\eta\sp5$-cyclopentadienyl)($\eta\sp2$-ethylene)iron reacts with 5$\sp\prime$-O-dimethoxytritylnucleoside 3$\sp\prime$-phosphite esters to yield (dicarbonyl)($\eta\sp5$-cyclopentadienyl)iron(ethyl)phosphonates. These phosphonates appear to be stable to the conditions commonly used to construct oligonucleotides by phosphoramidite methodology. This chemistry has been extended to the formation of a dimer on …

The questions were: (1) What categories of thinking were evident in the language and behaviors of young learners? (2) What environmental factors contributed to the development of children's thoughts and ideas?The thinking of nine first graders was described by semantic maps, direct observation, video and audio tapes, and analyzed using the categories of Bloom's Taxonomy and Tough's …

The Interaction Of Parishioner Gender And The Pedestal Effect As Influences Upon The Friendships Of Catholic And Protestant Clergy., Nanette Marie Matthews

Theses and Dissertations

The present investigation employed Wright's self-referent model of relationships in the examination of clerical friendships. It was hypothesized that the pedestal effect would be strongest for Catholic women, followed by Protestant women, Catholic men, and Protestant men, and that this variable would be inversely related to the total relationship index obtained from parishioners, the level of acquaintanceship as indicated by parishioners, and the total relationship index completed by clergy/controls toward their best friends. Hypotheses were offered regarding certain scales from the Acquaintance Description Form-Final (ADF-F). It was expected that utility and security values would tend to be high for clergy, …

Theses and Dissertations

Young chronic mentally ill persons are individuals whose needs for treatment are well documented. Within the context of existing mental health systems, the client is generally faced with the need to be able to seek out services. With sobering regularity, these persons are quite poorly prepared to communicate their needs effectively.The present research proposed that improvements in the assertive communication skills of young chronic mentally ill persons would promote improvements in their interactions with caregivers. This study was undertaken to investigate a videotape strategy for the training of assertiveness.The sample for this study consisted of 42 male and female volunteers …

Experimental Evaluation Of Design Variables For Two-Dimensional Confined Jet Thrust Vector Control Nozzles, Timothy M. Hawkes

Theses and Dissertations

An experimental study of the axial and vectoring performance of two - dimensional (2-D) confined jet thrust vector control (CJTVC) nozzles was performed. The effects of adding secondary injection ports and changing exit height and secondary injection port location were studied on several 2-D CJTVC nozzles. The axial and vectoring performance results for these nozzles were measured over a range of pressure ratios. An analytical method for predicting flow separation was found to be applicable to these nozzles. Guidelines for designing 2-D CJTVC nozzles, that can be vectored using secondary injection, were established.

A Multiple Model Adaptive Estimator Using First And Second-Order Acceleration Models For Use In A Forward-Looking Infrared Tracker, Barbara J. Niblett

Theses and Dissertations

The performance of a multiple model adaptive estimator (MMAE) for an enhanced correlator/forward-looking-infrared tracker for airborne targets is analyzed in order to improve its performance. Performance evaluation is based on elemental filter selection and MMAE estimation error sizes and trends. The elemental filters are based on either first or second-order acceleration models. Improved filter selection is achieved by using acceleration models that separate the frequency content of acceleration power spectral densities into non- overlapping regions with second-order models versus the more traditional overlapping regions with first-order models. A revised tuning method is presented. The maximum a posteriori (MAP) versus the …

Investigation Of Adaptive Controllers For Puma Trajectory Tracking, Daniel J. Sims

Theses and Dissertations

Two robust model-based controllers and two decentralized adaptive controllers are experimentally evaluated. Algorithm evaluation is motivated by the need for controllers with good high speed tracking under varying payload conditions. The test case is a PUMA-560 robotic manipulator operating over the standard test suite. The model-based controllers are made robust by the addition of either an auxiliary input term or an adaptive feedforward compensator based on Lyapunov Theory. The model-based auxiliary input controller (MBAIC) adapts the gain matrices used in computing an additional torque to be combined with model-based feedforward and PD feedback torques. The adaptive model-based controllers adapt the …

An Alternative Algorithm For Discrete-Time Filtering, Frederick H. Zeitz Iii

Theses and Dissertations

The discrete-time Kalman filter is a conditional mean estimator of the states of a linear stochastic process, conditioned on the previous state and current measurements. It assumes that the states and noise inputs can be represented as jointly Gaussian random variables. The influence diagram is a decision analysis tool. Under certain conditions, it can represent continuous, jointly Gaussian random variables. The conditioning order of the random variables may be changed (using Bayes' rule) so that any random variable can be conditioned on any other subset of random variables in the diagram. Under these conditions, an influence diagram can represent the …

The Expanding Rol Of The President As Commander-In-Chief Since World War Ii, David E. Kugler

Theses and Dissertations

While conflict has always existed between the president and the Congress over war-making roles, the president's Commander-in-Chief role has expanded significantly since World War II. This study examines expansion of presidential power in terms of the establishment of the United States as a world economic and political power and the development of nuclear weapons.

Case studies were selected from each of the administrations from Truman through Reagan to illustrate these points. The Truman administration is studied in terms of the war in Korea and the advent of the limited war concept in a nuclear-powered world.

President Eisenhower's massive retaliation strategy …

Alice L. Milligan: The Celtic Twilight's Forgotten Star, Kathryn J. O'Hehir

Theses and Dissertations

During the course of a historical examination of any given time period, persons and events are remembered in some texts and forgotten in others. The historical process of selection and rejection of materials is, in itself, the subject of much study. This study unearths a forgotten turn of the century Irish patriot named Alice L. Milligan, a Protestant nationalist writer from County Tyrone, Northern Ireland.

She is worthy of study in that she breaks traditional sectarian lines still drawn in Ireland today, where the stereotype prevails that only Catholics desire a reunited Ireland, with Protestants desiring inclusion with Great Britain. …

Relationship Of Adolescent Self-Image To The Risk Of Pregnancy, Vicki Wessman Downey

Theses and Dissertations

Adolescent pregnancy remains as one of the most pervasive socio- heaUh problems present in the United States. The health, economic, and social risk concomitant with adolescent pregnancy impacts on the child, mother, father, and society. Adolescent pregnancy, the problem that has not gone away, is an endemic phenomenon requiring long-term systematic intervention. It is imperative that underlying factors which contribute to this problem be identified so that subsequent research and educational programs can impact to reduce the problem.

One of the significant factors in teen pregnancy is low self esteem and self-concept. The purpose of this study was to examine …
