Obstacle Annotation By Demonstration, Michael David Clement
Obstacle Annotation By Demonstration, Michael David Clement
Theses and Dissertations
By observing human driving with a “digital head" (combined video camera and accelerometers) and taking a few hand annotations, we can automatically annotate regions in a robot's field of view that should be interpreted as obstacles to be avoided. This is accomplished by detecting the movement for a given frame in a video. Some hand annotations of video frames are necessary and they are used to create Probability Grids. Using the movement data and the Probability Grids, it is possible to annotate large amounts of video data quickly in an automated system.
The Effect Of Birth Order On Infant Injury, Heather L. Van Duker
The Effect Of Birth Order On Infant Injury, Heather L. Van Duker
Theses and Dissertations
Pediatric injury is both common and expensive. Finding ways to prevent pediatric injury is a major public health concern. Many studies have investigated various aspects of pediatric injury, and some suggest that birth order may be an important risk factor for pediatric injury. This study further examined the relationship of birth order with pediatric injury, specifically studying the association of birth order with emergency department-attended infant injury while adjusting for other important family and individual covariates. Data for analysis included Utah birth certificate, death certificate, and hospital emergency department datasets, which were probabilistically linked to obtain complete demographic and injury …

Evaluating The Application Of Modularity To Reduce Market Risk In Technology Push Products, Aaron John Hopkinson
Theses and Dissertations
Technology push product development presents a number of challenges over the more typical market pull product development. Despite these challenges, enough advantages exist to motivate firms to develop technology push products at greater risk. Modularity is a tool that can address some of these challenges. Currently most research and application of modularity have focused on market pull product development efforts. The research in this thesis explores the value of modularity in technology push product development through the development of methods and the analysis of 68 example products including 35 technology push products. A method has been developed for quantifying the …
Hope For The Fatherless?: A Grounded Interpretive Approach, Anna Manja Larcher
Hope For The Fatherless?: A Grounded Interpretive Approach, Anna Manja Larcher
Theses and Dissertations
Psychology's literature regarding fatherlessness is not only grim, mainly pointing out the negative consequences of fatherlessness, but it also does not provide much specific information about fatherless individuals' experiences. A pilot study revealed that fatherless individuals do not always suffer from the loss of their father and that they also have the ability to overcome the negative consequences commonly associated with father loss. The research questions for this study presented themselves naturally after reviewing the literature and after considering the results of my pilot study, namely, “What do fatherless individuals actually experience in being fatherless, and what is the nature …
Observational Studies Of Software Engineering Using Data From Software Repositories, Daniel Pierce Delorey
Observational Studies Of Software Engineering Using Data From Software Repositories, Daniel Pierce Delorey
Theses and Dissertations
Data for empirical studies of software engineering can be difficult to obtain. Extrapolations from small controlled experiments to large development environments are tenuous and observation tends to change the behavior of the subjects. In this thesis we propose the use of data gathered from software repositories in observational studies of software engineering. We present tools we have developed to extract data from CVS repositories and the SourceForge Research Archive. We use these tools to gather data from 9,999 Open Source projects. By analyzing these data we are able to provide insights into the structure of Open Source projects. For example, …
The Role Of Prolactin In Ccl28 Regulation, Jennie Hyde
The Role Of Prolactin In Ccl28 Regulation, Jennie Hyde
Theses and Dissertations
Infants are born with naive immune systems, making them susceptible to a variety of infections. In order to protect the newborn infant it is important that mothers be able to pass protective IgA antibodies to their infants through breast milk. B cells that produce IgA enter the mammary tissue during lactation and secrete IgA into the milk. During pregnancy, the mammary tissue expresses high levels of chemokines, molecules that allow lymphocytes to selectively home to specific tissues. The chemokine CCL28 has been shown to be upregulated during both pregnancy and lactation, and is vital for the ability of IgA-producing B …
Development Of An H-Alpha Index For The Detection Of Pms Candidates In Young Open Clusters, Liberty Rae Evanko
Development Of An H-Alpha Index For The Detection Of Pms Candidates In Young Open Clusters, Liberty Rae Evanko
Theses and Dissertations
One phase of formation of medium- and low-mass stars is the optically visible phase known as the pre-main-sequence or PMS phase. In order to further the understanding of this phase, more of these PMS objects need to be identified and classified. Previous techniques have used photometry to identify possible PMS objects by their characteristic Hα emission. Once identified these objects can be studied spectroscopically yielding complete PMS classification. This study develops a method to locate these emission objects that overcomes two limitations of previous techniques. The first limitation is the need for the creation of reddening maps. It is eliminated …
Stylized Hatching For 3d Animation, Trent Fielding Crow
Stylized Hatching For 3d Animation, Trent Fielding Crow
Theses and Dissertations
Much research has been done in creating non-photorealistic renderings of objects that mimic the look of hand-made drawings by traditional artists. This thesis extends work in this area by presenting an NPR hatching method that can be applied to 3D animated films to help them feel more hand drawn. In contrast to most other NPR methods, this method preserves the 3D lighting and effects of the film that make it interesting to watch. This process includes a procedural algorithm to create a hatching pattern that can be easily integrated into any film's pipeline that uses Renderman. In addition, we create …
One-Dimensional Performance Modeling Of Centrifugal Flow Vaned Diffusers, Jamin J. Bitter
One-Dimensional Performance Modeling Of Centrifugal Flow Vaned Diffusers, Jamin J. Bitter
Theses and Dissertations
The Two Element in Series (TEIS) and Two Zone models stand out as powerful tools that enable deeper understanding of compressor stage designs after they have been tested. The insights gained from these investigations have aided in improving new stage designs. Up to now, it has only been possible to use the TEIS and Two Zone models for analysis of test data due to the inability to predict the four required input parameters for untested machines. Empirical models for the TEIS and Two Zone model input parameters, ETAa5, ETAb5, Chi5, and DELTA5p, for two different types of vaned diffusers, channel …
Graphical And Bayesian Analysis Of Unbalanced Patient Management Data, Emily Stewart Righter
Graphical And Bayesian Analysis Of Unbalanced Patient Management Data, Emily Stewart Righter
Theses and Dissertations
The International Normalizing Ratio (INR) measures the speed at which blood clots. Healthy people have an INR of about one. Some people are at greater risk of blood clots and their physician prescribes a target INR range, generally 2-3. The farther a patient is above or below their prescribed range, the more dangerous their situation. A variety of point-of-care (POC) devices has been developed to monitor patients. The purpose of this research was to develop innovative graphics to help describe a highly unbalanced dataset and to carry out Bayesian analyses to determine which of five devices best manages patients. An …
Hidden Doublings: A Context For Understanding Jean D'Arras's Mélusine Ou La Noble Histoire De Lusignan, Kathryn Rimmasch
Hidden Doublings: A Context For Understanding Jean D'Arras's Mélusine Ou La Noble Histoire De Lusignan, Kathryn Rimmasch
Theses and Dissertations
At the end of the fourteenth century Jean d’Arras rewrote a popular folktale. The tale told how Mélusine, a fairy who was serpent from the navel down every Saturday, married a knight and founded the fortress of Lusignan. In his introduction to the tale Jean d’Arras presents the ideas of four authority figures to convince the reader that fantastical things are possible and that his work should be taken seriously. These authority figures are David, Aristotle, Paul and Gervaise de Tilbury. It is the contention of this thesis that Jean d’Arras presents these figures in his introduction to provide context …
Reducing Power In Fpga Designs Through Glitch Reduction, Nathaniel Hatley Rollins
Reducing Power In Fpga Designs Through Glitch Reduction, Nathaniel Hatley Rollins
Theses and Dissertations
While FPGAs provide flexibility for performing high performance DSP functions, they consume a significant amount of power. Often, a large portion of the dynamic power is wasted on unproductive signal glitches. Reducing glitching reduces dynamic energy consumption. In this study, retiming is used to reduce the unproductive energy wasted in signal glitches. Retiming can reduce energy by up to 92%. Evaluating energy consumption is an important part of energy reduction. In this work, an activity rate-based power estimation tool is introduced to provide FPGA architecture independent energy estimations at the gate level. This tool can accurately estimate power consumption to …

Analysis Using Smoothing Via Penalized Splines As Implemented In Lme() In R, John R. Howell
Theses and Dissertations
Spline smoothers as implemented in common mixed model software provide a familiar framework for estimating semi-parametric and non-parametric models. Following a review of literature on splines and mixed models, details for implementing mixed model splines are presented. The examples use an experiment in the health sciences to demonstrate how to use mixed models to generate the smoothers. The first example takes a simple one-group case, while the second example fits an expanded model using three groups simultaneously. The second example also demonstrates how to fit confidence bands to the three-group model. The examples use mixed model software as implemented in …
High Gain Low Power Operational Amplifier Design And Compensation Techniques, Lisha Li
High Gain Low Power Operational Amplifier Design And Compensation Techniques, Lisha Li
Theses and Dissertations
This dissertation discusses and compares the existing compensation methods for operational amplifiers. It explores a method to stabilize the op amps without sacrificing bandwidth to the same degree that commonly used methods do. A creative design methodology combining intuition, mathematical analysis, and mixed level simulation is explored for the new compensation scheme. The mixed level approach, associating system level simulation for most circuits along with device level simulation for some critical analog circuit paths, is presented to verify the behavior of new design concepts in an effective way. This approach also provides sufficient accuracy to predict the circuit performance realistically. …
Tessellated Surface Machining, Jiewu Lu
Tessellated Surface Machining, Jiewu Lu
Theses and Dissertations
Sculptured surface machining (SSM) is the end milling of sculptured surfaces with multi-axis machine tools. SSM consists of the tessellated model machining (TMM) and the parametric model machining (PMM). The former is gaining more and more attention over the past decade because it offers many advantages over the latter. New methods for various machining stages of TMM are proposed in this dissertation. First, in the 5-axis finish machining stage, a 3-dimension Configuration-space (3D C-space) machining method is presented. Next, in clean-up machining stage, an effective and creative approach is introduced. Finally, a complete TMM system is developed. The TMM system …

Nearly all colleges and universities are using some form of e-learning system, usually an expensive course management system (CMS), to create online course offerings or to enhance regular, classroom-oriented courses. Our university has invested a large amount of resources into purchasing and supporting one of the two most popular CMS vendors, and it has become imperative to understand what the effects from using this technology have been, as well as how we can improve the integration of this and other educational technologies into different instructional contexts. This project, through a combination of surveys, call-log analysis, and interviews, was used to …
Two Sides Of The Same Coin? The Differing Roles Of Assets And Consumer Debt In Marriage, Jeffrey P. Dew
Two Sides Of The Same Coin? The Differing Roles Of Assets And Consumer Debt In Marriage, Jeffrey P. Dew
Faculty Publications
This study examines whether assets and consumer debts relate to change in marital satisfaction and conflict in opposing ways or in independent ways. It also tests whether these relationships are direct or mediated. Using a nationally representative longitudinal sample, the results indicate that assets and consumer debt influence change in marital outcomes in mostly independent rather than complementary ways. Consistent with prior literature, assets work indirectly by decreasing feelings of economic pressure. Consumer debt, however, directly predicts changes in marital conflict, even after controlling for variables in the family stress model. Debts also act indirectly by decreasing depression once economic …

Feature-Based Mini Unmanned Air Vehicle Video Euclidean Stabilization With Local Mosaics, Damon Dyck Gerhardt
Feature-Based Mini Unmanned Air Vehicle Video Euclidean Stabilization With Local Mosaics, Damon Dyck Gerhardt
Theses and Dissertations
Video acquired using a camera mounted on a mini Unmanned Air Vehicle (mUAV) may be very helpful in Wilderness Search and Rescue and many other applications but is commonly plagued with limited spatial and temporal field of views, distractive jittery motions, disorienting rotations, and noisy and distorted images. These problems collectively make it very difficult for human viewers to identify objects of interest as well as infer correct orientations throughout the video. In order to expand the temporal and spatial field of view, stabilize, and better orient users of noisy and distorted mUAV video, a method is proposed of estimating …

Understanding The Experiences Of Instructors As They Adopt A Course Management System, Charles R. Graham, Gregory L. Waddoups, Richard E. West
Faculty Publications
In this study, we used qualitative methods to help us better understand the experiences of instructors as they are persuaded to adopt a course management system and integrate it into their teaching. We discuss several patterns explaining how instructors implemented Blackboard, a CMS, by experimenting with individual features, facing both technical and integration challenges, and attempting to adapt Blackboard features to match their goals and practices. We also give explanations for why instructors either a) embraced the tool and grew more dependent on it, b) reduced their use of the tool to only some features, or c) discontinued the tool …
