Limitations Of Methods For Determining The Position Of The Center Of Mass Of A Human Subject Performing A Sit-Up, Terrence Chadwick Smith

Dissertations and Theses

The knowledge of the position of the center of mass of a human subject performing a sit-up could help us understand the coordination of the sit-up motion. This thesis investigates the limits in three methods of determining the center of mass of a human subject. The three methods are the anthropometric method, the dynamic method, and the static torque method. The anthropometric method is a standard method that uses measurements of the subject to estimate the mass properties of individual segments of the body. The center of mass of the body is calculated from the mass and positions of the …

Time-Based Clustering And Its Relationship With Mutual Information Theory, Charles R. Tolle

Utah Space Grant Consortium

This paper re-introduces the concepts of TimeBased Clustering (TBC). Also, the ideas of oversampling and embedding time are introduced in connection with mutual information theory. These concepts are then extended through the use of the Time-Based Clustering (TBC) problem. Mutual information curves for the Rössler system are shown to match a slice through the rich cost function space spanned by the Time-Based Clustering (TBC) solution. In closing, some possible repercussions of this find are discussed.

Examination Of The Combustion Morphology Of Ziconium Carbide Using Scanning Electron Microscopy, Brian R. Newbold

Utah Space Grant Consortium

Calculation of viscous particle damping of acoustic combustion instability in solid propellant motors requires an understanding of the combustion behavior of added particles and oxides. A simple hydrogen/oxygen flame was used to ignite carefully sieved zirconium carbide particles which were impacted on slides at different levels below the burner.

Scanning electron microscopy revealed that zirconium carbide has a complex heterogeneous combustion morphology. Initially, particles are partly vitreous and crystalline with a complex surface area. Upon ignition, particles round, but soon wrinkle as zirconium oxide deposits on the surface. Such morphology information is useful to refine viscous damping calculations.

Gps Tracking For Small Sounding Rockets, Darin K. Fowers

Utah Space Grant Consortium

Active areas of research often create the need for improved technology to make observations in a way that has not previously been utilized. Such is the case with middle atmospheric research. This 60 to 120 km region of the atmosphere is too low to be directly probed by satellites and too high to be probed by research airplanes or high altitude balloons. Sounding rockets are the only vehicle that can carry instruments for in situ measurements. Up until now only a few methods have been available to track the location of a sounding rocket - radar skin tracking, radio beacon …

Absolute Solar Transmittance Interferometer, Arthur W. Dybdahl

Utah Space Grant Consortium

The University of Denver's Absolute Solar Transmittance Interferometer (ASTI) has been developed to make high-resolution infrared (TR) radiometric measurements of the incident solar radiance and irradiance at the Earth's surface. It is a research instrument that provides spectral data of high scientific interest in the short-wave infrared (SWIR) band covering 0.97 to 5.13 µm. This band contains about 20 percent of the suns incident energy, having a significant impact on global as well as regional climate. ASTI spectra are used to provide significant radiometric information describing the SWlR transmittance and absorption properties of the atmosphere. The ASTl research program and …

Flow Past Bluff Bodies, Thad S. Morton

Utah Space Grant Consortium

More than a century ago Kirchhoff solved for the velocity distribution within an elliptical patch of uniform vorticity. That solution became the basis for all further studies of elliptical vortices and has been regarded as the only known exact solution for a steady, elliptical patch of uniform vorticity. In the present paper, an exact solution for a new elliptical patch of uniform vorticity is presented. The vortex is constructed of streamlines of constant eccentricity. By specifying a velocity distribution along either of the principle axes of the vortex, continuity between differentially-spaced streamlines provides the velocity distribution throughout the vortex. Some …

Internet Access For Instrumental Control And Data Viewing At Bear Lake Observatory, Kerry M. Nelson

Utah Space Grant Consortium

Two departments at Utah State University have collaborated to operate an observatory near Bear Lake, Utah. The purpose of the observatory is to study various phenomena in the upper atmosphere, and houses such instruments as high-power CCD cameras, a radar system, and others. Until recently, only one instrument has had the capability of being controlled and monitored remotely. Since the other instruments do not have this capability, they must be set up and left running, only to have a person drive up to the observatory to check their operation after a given amount of time. This monitoring system is not …

Microgravity Effects On Water Flow And Distribution In Unsaturated Porous Media, Scott B. Jones, Dani Or

Utah Space Grant Consortium

Several aspects of the physical processes of liquid flow and distribution within partially saturated porous media are altered in the reduced gravity conditions (microgravity) of orbiting spacecraft. The objectives of this study were to simulate and test measured flow and distribution in porous media from a microgravity environment using conventional capillary flow theory. Two past microgravity experiments studying water supply and uptake in porous media took place on a U.S. space shuttle, titled ASC-1, and on the Russian space station Mir, titled Greenhouse-2. Data from microgravity and ground experiments were simulated using similar physical flow models by elimination of the …

Validation Study Of A Novel Neonatal Pneumotach, Scott A. Kofoed

Utah Space Grant Consortium

We have developed a pneumotach for measuring respiratory gas flows in humans and or animals. The pneumotach enables the monitoring of respiratory and metabolic function in human subjects over extended periods of time. A bench study was conducted to validate the new pneumotach system against other predicate devices. The pneumotach under test compared well to the predicate devices used.

Binary Classification Of Wind Fields Through Hypothesis Testing On Scatterometer Measurements, Paul E. Johnson

Utah Space Grant Consortium

Scatterometers are radars specially designed to nearsurface wind over the ocean from space. Traditional scatterometer wind estimation inverts the model function relationship between the wind and backscatter at each resolution element, yielding a set of ambiguities due to the many-to-one mapping of the model function. Field-wise wind estimation dramatically reduces the number of ambiguities by estimating the wind at many resolution elements, simultaneously, using a wind model that constrains the spatial variability of the wind. However, the appropriate choice of the model order needed for a particular wind field is not known a priori. The approximate model order is valuable …

Temporal Change Enhancement In Multispectral Images Remotely Sensed From Satellites, William P. Pfaff

Utah Space Grant Consortium

The application of principal components analysis to multispectral satellite images is a routine way to present the data in false-color composite images. These composite images include a very high percentage of available information and have no correlation between the displayed colors. The transformation of multispectral image data into its principal components is also an effective way to separate image information from noise. This paper describes a procedure for temporal change enhancement which exploits both the decorrelation and noise isolation properties of the principal components transformation. Using simulated temporal change, this procedure was demonstrated to be more effective than the standard …

Development Of A Full-Spectrum Raman Device For Detection Of Environmental Contaminants, David G. Smith

Utah Space Grant Consortium

NASA needs sensors to accurately monitor the water and atmospheric quality in its space habitat. Concerns for health and safety necessitate the development of sensors to measure common atmospheric gas concentrations, as well as trace contaminants (low ppm or ppb), including both combustible and noncombustible gases. The University of Utah is developing an enhanced Raman monitoring system to detect airborne, environmental contaminants. We have collected laboratory data to benchmark current laser Raman technology for gas analysis, which provides a reference for future developments. The objective of this project was to design a prototype gas-phase monitor, incorporating new technology that would …

Perceptions Of Teachers Toward Change In Rural North Dakota High Schools., Roy Michael Tapp

Theses and Dissertations

Rural schools rarely seem to get attention from prestigious sections of the academic community, especially concerning the issues of research, change, and rural teachers. Change in any form must be promptly and positively addressed as to diminish negative influences in the school setting. This study's intentions were twofold: to examine the perceptions that rural North Dakota high school teachers have about the process of change and to assess the extent to which the background factors of teachers contributes to these perceptions.For the purpose of this study, 162 teachers' responses to 14 items in the section of Intentional changes in the …

Qualitative Research Methods: An Essay Review, Les Mclean, Margaret Myers, Carol Smillie, Dale Vaillancourt

Education Policy Analysis Archives (EPAA)

The authors ask us to explore the topic of "qualitative confirmation" in relation to the processes and outcomes of qualitative research practice. The question that directs their inquiry is "how can we make a case that qualitative data or findings warrant the inferences about the topics we are studying?" We review the historical discussion of confirmation theory within the logic of discovery, consider hypothesis generation and methodological decisions as instruments of the research process and then apply the Miller and Fredericks framework of rules to a published report of qualitative research. ...

Vcu Voice (1997-06-09)

VCU Voice, 1988-1998

VCU Today, the University’s first official administrative organ, began as a somewhat irregular monthly publication but moved to a bi-weekly newspaper format in the 1980s. The newspaper changed its name to VCU Voice in 1988 and ten years later it appeared under the title UniverCity News. As it neared the end of its run as a physical newspaper, the publication became simply VCU News. These four publications were essentially the same periodical published under different titles by the Office of University Relations. VCU News appeared online for the first time in 2002.

Calculation Of Electronic Coupling Matrix Elements For Ground And Excited State Electron Transfer Reactions: Comparison Of The Generalized Mulliken–Hush And Block Diagonalization Methods, Robert J. Cave, Marshall D. Newton

All HMC Faculty Publications and Research

Two independent methods are presented for the nonperturbative calculation of the electronic coupling matrix element (Hab) for electron transfer reactions using ab initio electronic structure theory. The first is based on the generalized Mulliken–Hush (GMH) model, a multistate generalization of the Mulliken Hush formalism for the electronic coupling. The second is based on the block diagonalization (BD) approach of Cederbaum, Domcke, and co-workers. Detailed quantitative comparisons of the two methods are carried out based on results for (a) several states of the system Zn2OH2+ and (b) the low-lying states of the benzene–Cl atom complex and its contact ion pair. Generally …
