The Effect Of Varying Weightload Intensities On Biceps Curl Technique, Jeffrey C. Gailhouse

Masters Theses

This study described biomechanical deviations from proper biceps curl technique specifically in the shoulder, trunk, body and knee angles, that occurred in response to varying intensities of an individual's 1 RM (repetition maximum). Ten college age males participated in the study. Subjects were required to perform one repetition at 60%, 70%, 80%, 90% and 100% of his 1 RM. The only differentiating factor was the order in which the five intensities were performed. Condition order was randomized to minimize bias. Movement was filmed with a high-speed motion picture camera, digitized and then analyzed with computer software.

The findings indicated that …

Optical Haar Wavelet Transforms Using Computer Generated Holography, Peter G. Block

Theses and Dissertations

This research introduces an optical implementation of the continuous wavelet transform to filter images. The wavelet transform is modeled as a correlation process and is implemented with a Vander Lugt correlator. The orthonormal basis set used is composed of two one-dimensional Haar functions and a two-dimensional Haar function. Each wavelet, as well as its first two dyadic scalings, is implemented with computer generated holography. The Interferogram method, which represents a function only in terms of its phase, is used to encode the wavelet functions. The results are imaged onto a CCD array and captured using a framegrabber. The optical results …

Cathodoluminescence Spectroscopy Of Zinc Germanium Phosphide Zngep2, Michael R. Gregg

Theses and Dissertations

Zinc Germanium Phosphide (ZnGeP₂) is a nonlinear semiconductor suitable for use as a laser tuning element over the two to six micron wavelength range. Although this crystal has been studied in the past, its luminescent properties are not yet well understood. In this present study, ZnGeP₂ has been examined using cathodoluminescence spectroscopy (CL). Specifically, the spectral dependence of the CL was obtained as a function of electron beam energy, beam current and temperature. The resulting CL was found to be polarized with a peak structure that was dependent on the polarization. This peak structure observed by CL …

An Approximate Solution For The Linearized Spinup Dynamics Of A Dual-Spin Spacecraft, David L. Kinney

Theses and Dissertations

An approximate solution is obtained for the linearized equations of motion for the spinup dynamics of a dual-spin spacecraft. The approximation is obtained from the WKB (Wentzel, Kramers, and Brillouin) method, which usually generates a divergent series. Comparison between the WKB solution and the numerically integrated solution are used to study the effects of spinup torque magnitude and the number of WKB terms used on the accuracy of the approximation. The WKB method generates accurate approximations for small spinup torques using as few as two terms in the series when no singularities are present in the WKB terms during the …

Behavior Of A Titanium Matrix Composite Under Quasi-Static Tensile And Compressive Loading, Keith L. Bearden

Theses and Dissertations

Quasi-Static tensile and compressive testing was performed on a unidirectional titanium matrix composite. The specific material was SCS-9/β 21S. The initial tensile and compressive modulus for both laminates was the same. The ninety degree laminate had a tensile and compressive modulus of 115.89 GPa. The zero degree laminate had a tensile and compressive modulus of 197.51 GPa. The ninety degree laminate exhibited a three stage stress/strain response in tension. The first stage is completely linearly elastic, however, partial debonding of the fiber from the matrix was observed. This partial debased did not effect the stress/strain response. The second stage is …

Behavior Of A Quasi-Isotropic Ply Metal Matrix Composite Under Thermo-Mechanical And Isothermal Fatigue Loading, Karl A. Hart

Theses and Dissertations

This study investigated the behavior of the SCS6/Ti-15-3 metal matrix composite with a quasi-isotropic layup when tested under static and fatigue conditions. Specimens were subjected to in-phase and out-of-phase thermo- mechanical and isothermal fatigue loading. In-phase and isothermal loading produced a fiber dominated failure while the out-of-phase loading produced a matrix dominated failure. Also, fiber domination in all three profiles was present at higher maximum applied loads and al three profiles demonstrated matrix domination at lower maximum applied loads. Thus, failure is both profile dependent and load equipment. Additional analyses, using laminated plate theory, Halpin-Tsai equations, METCAN, and the Linear …

Development Of An Engine/Airframe Performance Matching Scheme For Jet Engine Retrofit, Alan Lach

This paper introduced the ideas of solution surfaces, constraint/thrust diagrams, quality measures and linear regression analysis for the engine design problem. It considered the application of the jet engine design software ACSYS, MISS, and ONX along with statistical analysis software, SAS. Modeling techniques and linear regression analysis were used to minimize iteration while searching a wide range of design variables. Improvements …

A Comparison Of Computational Fluid Dynamics Computer Programs For Hypersonic Propulsive Nozzle Flowfields, Kennedy B. Wilson Jr.

Theses and Dissertations

This study compared the results of two computer programs, a flux- difference-splitting (FDS) Godunov-based scheme and the SCPAMjet Hypersonic Nozzle (SCHNOZ) paraobolized Navier-Stoke's code using MacCormack's method, applied to a hypersonic nozzle flowfield. Two different nozzle geometries were investigated at three Mach numbers along a typical hypersonic flight trajectory. A direct compariosn between the SCHNOZ and FDS programs was made by numerically solving the steady Euler equations using a frozen flow assumption in the nozzle. The frozen flow SCHNOZ code is currently 6 to 10 times more efficient in terms of computational time than the FDS frozen flow code. The …

Increasing The Corrected Field Of View Of An Adaptive Optical Telescope, Dustin C. Johnston

Theses and Dissertations

Current adaptive optical telescope designs use a single deformable mirror (DM) to compensate for atmospheric distortion. The corrected field of view (FOV) of an adaptive optics system could be increased through the use of multiple DMs optically conjugated to corresponding planes which sample the turbulence region in altitude. Often, the atmospheric turbulence responsible for the degradation of telescope images is concentrated in several layers. Each DM would correct for the component of the total wavefront in the pupil contributed by one or more layers. If the atmosphere does not possess a layered structure, the best fit of the turbulence profile …

A Radiosity Approach To Realistic Image Synthesis, Richard L. Remington

Theses and Dissertations

The Air Force Institute of Technology (AFIT) has not had the capability to generate photorealistic images. This thesis is a research effort to implement such a system at AFIT, and to apply knowledge from the particle transport community to this problem. Investigation into various techniques for generating photorealistic images led to the conclusion that the radiosity method would serve as the foundation for development. This is because of the increased accuracy of the diffuse reflections with the radiosity method and the fact that the images produced with radiosity axe view-independent. Two distinct tools to generate photorealistic images axe described. The …

Efficient Derivation And Approximations Of Cepstral Coefficients For Speech Coding, Kimberly A. Limcangco

Theses and Dissertations

A new formulation is presented for the calculation of cepstral coefficients directly from measured sine wave amplitudes and frequencies of speech waveforms. Approximations to these cepstral coefficients are shown to be suitable for operation in a real-time speech coding environment. These results were encoded in the C programming language and then evaluated through experiments that were conducted on the McAulay-Quatieri Sinusoidal Transform Coder (STC).

Etann Hardware Implementation For Radar Emitter Identification, James B. Calvin Jr.

Theses and Dissertations

This study investigated classification of 30 radar emitters with 16 signal features using Intel's 80170NX chip, the Electronically Trainable Analog Neural Network (ETANN). Software tools were developed to characterize the ETANN sigmoidal transfer function for use in a custom simulator, known as Neural Graphics. Neural Graphics operates on a Silicon Graphics workstation. The Intel Neural Network Training System simulators were used in early experiments, but were found to be inefficient in training on data used in this research. Using a modified Neural Graphics simulator, single chip and multi-chip experiments were performed to provide benchmark results prior to performing chip-in-loop training. …

A Generic Template Extractor (Gentex) In C For Vlsi Design Verification, Kenneth J. Mcclellan Jr.

Theses and Dissertations

The problem of VLSI design verification through circuit extraction was analyzed. The problems of creating a simple template format, the permutability of pins, maintaining connectivity, and performance were focused on. A generic template extractor (GENTEX) was developed in the C programming language for use as a testbed to find solutions to these problems. Six different extraction algorithms were tested with GENTEX and compared based on performance. EDIF translation programs were used to interface with GENTEX on both the input and output sides. One translation program converted an EDIF representation of a schematic into the template format used by GENTEX. The …

Metacognition In The Elementary Classroom: An Exploration, Terri Anne Caffelle

Critical and Creative Thinking Capstones Collection

Metacognition is a practice which enables students to monitor their thought processes in order to think critically. Research indicates that when students are aware of their thinking they become better thinkers. The purpose of this thesis is to encourage teachers to give more attention to metacognition in the classroom. A review of the literature on metacognition is given. Next, classroom lessons are outlined which introduce fourth grade students to metacognition in the context of math problem solving. Finally, an initial assessment is given of how students' metacognitive and problem solving abilities have changed as a results of the curriculum. Before …

Restructuring For Mathematical Power: Techniques For Teaching Thinking In Algebra, Barbara D. Nelson

Critical and Creative Thinking Capstones Collection

Recent critiques of mathematics education have resulted in proposals to restructure learning and teaching for mathematical power. The new vision pictures the classroom as a community of learners where mathematics come alive as a useful tool in our technological society. However, many high school mathematics teachers are struggling to understand and implement the fundamental instructional change inherent in the vision. Written from the perspective of a high school teacher for experienced high school mathematics teachers, this thesis attempts to bridge vision and practice. To clarify the vision, current literature on reform in mathematics education is synthesized into a framework of …

Almost Difference Sets And Reversible Divisible Difference Sets, James A. Davis

Department of Math & Statistics Faculty Publications

Let G be a group of order mn and N a subgroup of G of order n. If D is a k-subset of G, then D is called a (m, n, k, λ₁, λ₂) divisible difference set (DDS) provided that the differences dd^'-1 for d, d' ∈ D, d ≠ d' contain every nonidentity element of N exactly λ₁ times and every element of G - N exactly λ₂ times. Difference sets are used to generate designs, as described by [4] and [9]. D will be …

An Analysis Of Student Math Scores Based Upon Teacher Training In The Instructional Theory Into Practice Model, Martha O'Kray

Dissertations

The main purpose of this study was to determine if teacher participation in Instructional Theory Into Practice (ITIP , Hunter, 1978) training resulted in any difference in student achievement. Student outcomes were measured by scores received on the district's Exit Level Mathematics Test (Roseville Community Schools, 1986).

The study took place in Roseville Community Schools. Six hundred forty-nine students and 32 teachers in Grades 3, 4, and 5 participated.

Fourteen teacher observations were included to confirm the appropriateness and frequency of ITIP strategies in classroom instruction. Observers using the Instructional S kills Observation Instrument (ISOI, Wolfe, 1984) scored non-ITIP-trained teachers …

Postmodern Constitutionalism As Materialism, Francis J. Mootz Iii

Michigan Law Review

Professor J.M. Balkin's recent essay in the Michigan Law Review assesses the implications that postmodernism holds for constitutional law. Although I agree with Balkin about many of the specific issues that he believes must be addressed in a postmodern constitutionalism, I find that his manner of talking about postmodernism is unproductive in an important way. Balkin quite correctly argues that a postmodern constitutionalism should not mimic the fragmented and superficial culture of postmodernity, nor should it devolve simply to normative claims that postmodernity is desirable and should be embraced or adopted within the law. However, Balkin's thesis that a postmodern …

Defining Computer Program Parts Under Learned Hand's Abstractions Test In Software Copyright Infringement Cases, John W.L. Ogilive

Michigan Law Review

This Note proposes a set of computer program part definitions that develop Learned Hand's abstractions test to make it more useful in software infringement cases. The Note takes no position on the proper scope of protection for software under copyright law, but argues that no consensus is possible on which program parts deserve copyright protection until courts recognize that computer programs are composed of components whose definition lies beyond judicial control. Program parts defined in conclusory legal terms will never provide a stable basis for reasoned debate over the conclusions presumed in the definitions.
