Pipelining Of Double Precision Floating Point Division And Square Root Operations On Field-Programmable Gate Arrays, Anuja Thakkar
Pipelining Of Double Precision Floating Point Division And Square Root Operations On Field-Programmable Gate Arrays, Anuja Thakkar
Electronic Theses and Dissertations
Many space applications, such as vision-based systems, synthetic aperture radar, and radar altimetry rely increasingly on high data rate DSP algorithms. These algorithms use double precision floating point arithmetic operations. While most DSP applications can be executed on DSP processors, the DSP numerical requirements of these new space applications surpass by far the numerical capabilities of many current DSP processors. Since the tradition in DSP processing has been to use fixed point number representation, only recently have DSP processors begun to incorporate floating point arithmetic units, even though most of these units handle only single precision floating point addition/subtraction, multiplication, …
Sensitivity Analysis Of Aashto's 2002 Flexible And Rigid Pavement Design Methods, Sanjay Shahji
Sensitivity Analysis Of Aashto's 2002 Flexible And Rigid Pavement Design Methods, Sanjay Shahji
Electronic Theses and Dissertations
Over the years pavement design has been based on empirical equations developed from the American Association of State Highway Transportation Officials (AASHTO) road tests. The various editions of the AASHTO pavement design guide have served well for several decades; nevertheless many serious limitations existed for their continued use as the nation's primary pavement design procedure. For example, the traffic loads and truck sizes have increased over the years, the AASHTO design equations were derived based on the climatic conditions present at the Road Tests site, and the issue of aging materials was not addressed in the design. To overcome these …
Modeling Of Atmospheric Refraction Effects On Traffic Noise Propagation, Ahmed El-Aassar
Modeling Of Atmospheric Refraction Effects On Traffic Noise Propagation, Ahmed El-Aassar
Electronic Theses and Dissertations
Traffic noise has been shown to have negative effects on exposed persons in the communities along highways. Noise from transportation systems is considered a nuisance in the U.S. and the government agencies require a determination of noise impacts for federally funded projects. There are several models available for assessing noise levels impacts. These models vary from simple charts to computer design models. Some computer models, i.e. Standard Method In Noise Analysis (STAMINA), the Traffic Noise Model (TNM) and the UCF Community Noise Model (CNM), have been used to predict geometric spreading, atmospheric absorption, diffraction, and ground impedance. However, they have …
Polarimetry Of Random Fields, Jeremy Ellis
Polarimetry Of Random Fields, Jeremy Ellis
Electronic Theses and Dissertations
On temporal, spatial and spectral scales which are small enough, all fields are fully polarized. In the optical regime, however, instantaneous fields can rarely be examined, and, instead, only average quantities are accessible. The study of polarimetry is concerned with both the description of electromagnetic fields and the characterization of media a field has interacted with. The polarimetric information is conventionally presented in terms of second order field correlations which are averaged over the ensemble of field realizations. Motivated by the deficiencies of classical polarimetry in dealing with specific practical situations, this dissertation expands the traditional polarimetric approaches to include …
Molecular Structure-Nonlinear Optical Property Relationships For A Series Of Polymethine And Squaraine Molecules, Jie Fu
Electronic Theses and Dissertations
This dissertation reports on the investigation of the relationships between molecular structure and two-photon absorption (2PA) properties for a series of polymethine and squaraine molecules. Current and emerging applications exploiting the quadratic dependence upon laser intensity, such as two-photon fluorescence imaging, three-dimensional microfabrication, optical data storage and optical limiting, have motivated researchers to find novel materials exhibiting strong 2PA. Organic materials are promising candidates because their linear and nonlinear optical properties can be optimized for applications by changing their structures through molecular engineering. Polymethine and squaraine dyes are particularly interesting because they are fluorescent and showing large 2PA. We used …
Listening To Student Voices: Fifth Graders' Perceptions Of Their Mathematics Learning Within The Context Of A Mathematics Reform, Elizabeth Hoffman
Listening To Student Voices: Fifth Graders' Perceptions Of Their Mathematics Learning Within The Context Of A Mathematics Reform, Elizabeth Hoffman
Electronic Theses and Dissertations
This qualitative study explored fifth graders' perceptions of their mathematics learning within the context of a reform effort. Students' voices are the focus of this study due to the paucity of literature on student learning from the students' perspective (Erickson & Shultz, 1992), particularly the elementary student (Gentilucci, 2004). The participants of this study, who in the past have been given a variety of labels including "disadvantaged" or "at-risk," clearly articulated, even in nonstandard English, their perceptions of their mathematics learning. They passionately explained what helped them learn mathematics as well as what impeded their mathematics learning and were often …

Information for this study was represented by online documents that were retrieved from DOE websites across the United States. Findings suggested that …
Health Attitudes, Knowledge And Literacy Of Primary Caregivers With Elementary School Children, Susan Stuib
Health Attitudes, Knowledge And Literacy Of Primary Caregivers With Elementary School Children, Susan Stuib
Electronic Theses and Dissertations
Previous research has indicated that physical activity and healthy eating in elementary school children are the exception rather than the norm. Increased attention to the rising rates of childhood obesity, coupled with the recognition that changes in the school environment are critical to reducing this trend, has intensified the need to adopt better practices in school nutrition, physical activity and physical education. Apart from being physically active, children need to learn fundamental motor skills and develop health related physical fitness (cardiovascular endurance, muscular strength and endurance, flexibility, and body composition). Primary caregivers play an important part in developing and teaching …

Landsat Scene Normalization Using Modis 250 Meter Tree Cover Map, Bernard Adusei
Landsat Scene Normalization Using Modis 250 Meter Tree Cover Map, Bernard Adusei
Electronic Theses and Dissertations
High spatial resolution Landsat Thematic Mapper (TM) and Enhanced Thematic Mapper Plus (ETM +) bands 4, 5, and 7 coupled with pre-existing Moderate Resolution Imaging Spectroradiometer (MODIS) 250m resolution maps as reference information were employed in an attempt to catalog anthropogenic impacts on the Congo Ba in's humid tropical forest. The utility of Landsat multi-spectral data depends both on the extent to which surface properties can be estimated from the radiometric measurements and on the ability to observe the surface through the atmosphere. Cloud cover is a major impediment to optical remote sensing of humid tropical regions. Accordingly, applications may …
Sauger Population Ecology In Three Missouri River Mainstem Reservoirs, Brian D. S. Graeb
Sauger Population Ecology In Three Missouri River Mainstem Reservoirs, Brian D. S. Graeb
Electronic Theses and Dissertations
Sauger Sander canadensis populations have experienced widespread declines across much of their range. Factors suspected to contribute to these declines include hybridization, exploitation, loss of spawning areas, and general habitat alterations associated with regulated rivers. Several sauger populations within the Missouri River basin are also experiencing similar declines, particularly in the headwaters of Montana, and the lower basin states of Nebraska and Missouri. However, sauger populations in many of the reservoirs in South Dakota (between Montana and the lower basin) have relatively stable populations. Given the paucity of information on factors influencing sauger population ecology in general, and Missouri River …

Factors Regulating Walleye Early Survival And Cohort Strength In Eastern South Dakota Glacial Lakes, Richard D. Zweifel
Factors Regulating Walleye Early Survival And Cohort Strength In Eastern South Dakota Glacial Lakes, Richard D. Zweifel
Electronic Theses and Dissertations
Walleye Sander vitreus is an important ecological component of glacial lake aquatic communities in eastern South Dakota, and the most popular sport fish in the region. Walleye populations in this region exhibit consistently poor or annually-variable reproductive success and are regularly stocked in an effort to maintain consistent recreational fisheries. However, current stocking programs are based on reproductive success from previous years rather than on expected reproductive success in the year which stocking occurs. Determination of walleye cohort strength at the larval life stage would provide a stocking prioritization system that would utilize the natural reproduction of in situ walleye …
