Matlab Implementation of a Tornado Forward Error Correction Code

Matlab Implementation of a Tornado Forward Error Correction Code

Date: May 2011
Creator: Noriega, Alexandra
Description: This research discusses how the design of a tornado forward error correcting channel code (FEC) sends digital data stream profiles to the receiver. The complete design was based on the Tornado channel code, binary phase shift keying (BPSK) modulation on a Gaussian channel (AWGN). The communication link was simulated by using Matlab, which shows the theoretical systems efficiency. Then the data stream was input as data to be simulated communication systems using Matlab. The purpose of this paper is to introduce the audience to a simulation technique that has been successfully used to determine how well a FEC expected to work when transferring digital data streams. The goal is to use this data to show how FEC optimizes a digital data stream to gain a better digital communications systems. The results conclude by making comparisons of different possible styles for the Tornado FEC code.

The Art-Union and Photography, 1839-1854: The First Fifteen Years of Critical Engagement between Two Cultural Icons of Nineteenth-Century Britain

The Art-Union and Photography, 1839-1854: The First Fifteen Years of Critical Engagement between Two Cultural Icons of Nineteenth-Century Britain

Date: August 2011
Creator: Boetcher, Derek Nicholas
Description: This study analyzes how the Art-Union, a British journal interested only in the fine arts, approached photography between 1839 and 1854. It is informed by Karl Marx’s materialism-informed commodity fetishism, Gerry Beegan’s conception of knowingness, Benedict Anderson’s imagined community, and an art critical discourse that was defined by Roger de Piles and Joshua Reynolds. The individual chapters are each sites in which to examine these multiple theoretical approaches to the journal’s and photography’s association in separate, yet sometimes overlapping, periods. One particular focus of this study concerns the method through which the journal viewed photography—as an artistic or scientific enterprise. A second important focus of this study is the commodification of both the journal and photography in Britain. Also, it determines how the journal’s critical engagement with photography fits into the structure and development of a nineteenth-century British social collectivity focused on art and the photographic enterprise.

Induced “motivation”

Induced “motivation”

Date: August 2011
Creator: Becker, April Melissa
Description: In the avian training community, a procedure has been utilized to maintain food reinforcer efficacy at high body weights. Elements of this procedure include limited holds and closed economies. To test this procedure, a baseline performance of keypecking on an FR 15 schedule at 80% ad lib weight for two pigeons was established. By imposing limited holds and a closed economy, rates of responding were increased compared to baseline, even while the pigeons were over 90% of their ad-lib body weights.

Chronic Insomnia and Healthcare Utilization in Young Adults

Chronic Insomnia and Healthcare Utilization in Young Adults

Date: August 2011
Creator: Bramoweth, Adam Daniel
Description: Chronic insomnia is a highly prevalent disorder in general and young adult populations, and contributes a significant economic burden on society. Previous studies have shown healthcare utilization (HCU) is significantly higher for people with insomnia than people without insomnia. One limitation with previous research is accurate measurement of HCU in people with insomnia is difficult due to a high co-morbidity of medical and mental health problems as well as varying operational definitions of insomnia. Assessing HCU in people with insomnia can be improved by applying research diagnostic criteria (RDC) for insomnia, using a population with low rates of co-morbid medical/mental health problems, and measuring HCU with subjective, objective, and predictive methods. The current study found young adults with chronic insomnia had greater HCU than normal sleepers, specifically on number of medications, and chronic disease score (CDS) estimates of total healthcare costs, outpatient costs, and predicted number of primary care visits. The presence of a medical and/or mental health problem acted as a moderating variable between chronic insomnia and HCU. Simple effects testing found young adults with chronic insomnia and a medical/mental health problem had the greatest HCU followed by normal sleepers with a medical/mental health problem, chronic insomnia, and normal ...

Teleport

Teleport

Date: August 2011
Creator: Bell, C.F. Davis
Description: This collection consists of a critical preface exploring the similarities between serialized comic books, realist fiction and the author’s own writing. The principle discussion concerns continuity, the connecting tissue between ancillary works of fiction, chronology, the function of time in the narrative of related stories, and the function of characters beyond the stories they inhabit. The stories within the collection revolve around an eccentric ensemble of suburban youth whose demoralized and violent actions are heavily influenced by defining moments of their past.

Testing the Impacts of Social Disorganization and Parochial Control on Public Order Crimes in Turkey

Testing the Impacts of Social Disorganization and Parochial Control on Public Order Crimes in Turkey

Date: August 2011
Creator: Bayhan, Kenan
Description: The primary focus of this study is to investigate the effects of social control mechanisms on public order crimes in Turkey. Supporting efforts of parochial control is a rising trend in crime control activities. Statements regarding the relationship between social disorganization variables, parochial control variables, and spatial distribution of crime have long been studied by researchers. Using the same assumptions in this study, I test their applicability to public order crimes in Turkey. The poverty and residential mobility variables had significant positive effect on public order crimes holding other structural and parochial variables constant. The number of public order crimes seems to be higher in provinces where there are more disrupted families. The number of public order crimes seems to be lower in provinces where there are more religious institutions. Overall, the results reveal that social structural variables and parochial control factors affect the institutional bases of provinces and partly affect the occurrence of public order crimes. Based on the study findings, several policy implications and recommendations for future research are suggested.

Lack of Evaluation as Evaluation: Analysis of an African American Woman’s Narrative

Lack of Evaluation as Evaluation: Analysis of an African American Woman’s Narrative

Date: August 2011
Creator: van Drunen, Vanessa
Description: This thesis examines an African American woman’s narrative about the day that her daughter was shot. Like many personal narratives of “frightening experiences,” the speaker in this narrative highlights the peak of her story, making sure her point is salient. In earlier analyses, it has been shown that evaluation tends to cluster around the peak of the narrative. In “The day my daughter got shot” we see that this event-filled narrative is not evaluated as predicted as there is no increased usage of evaluative devices at one single point in the narrative. Instead, it is a change in patterning of a number of linguistic and paralinguistic devices that conspire to bring special attention to the peak of the narrative. By examining multiple devices at once, it is seen that they create a cumulative effect that makes the story interesting and exciting, resulting in a successful narrative.

Orchestral Etudes: Repertoire-Specific Exercises for Double Bass

Orchestral Etudes: Repertoire-Specific Exercises for Double Bass

Date: August 2011
Creator: Unzicker, Jack Andrew
Description: In this project, frequently required double bass orchestral audition excerpts as well as their individual technical difficulties are identified. A survey of professional double bass players and teachers currently and formerly employed by major orchestras, universities, and conservatories have participated to validate the importance of four of the most frequently required orchestral excerpts: Ludwig van Beethoven’s Symphony No. 9, Mvt. 4, and Symphony No. 5, Mvt. 3; Richard Strauss’ Ein Heldenleben; and Wolfgang Amadeus Mozart’s Symphony No. 40, Mvt. 1. The survey respondents identified the primary and secondary technical concerns of each of the four excerpts. I have created technical studies, or etudes, that specifically address these difficulties and help fill a literary gap within the existing pedagogical resources for the double bass.

Relation Between the FITNESSGRAM® Ftness Assessment and Self-Reported Physical Activity Questions

Relation Between the FITNESSGRAM® Ftness Assessment and Self-Reported Physical Activity Questions

Date: August 2011
Creator: Tucker, Jacob
Description: The FITNESSGRAM® is regularly used to assess physical fitness (PF) of adolescents. In addition to the PF assessment, the FITNESSGRAM also includes self-report physical activity (PA) items. The purpose of this study was to examine whether the self-report aerobic, muscular strengthening, and flexibility PA behavior items indicated adolescents’ cardiorespiratory, muscular strength, and flexibility fitness and their body composition. Logistic regression analysis was used to examine the relation between the amount of PA and PF status. Adolescents not meeting the recommended PA amount had significantly higher odds of not achieving a healthy fitness status. Meeting the recommended PA amount was associated with achieving healthy PF status. Thus, adolescents’ amounts of aerobic, muscular strengthening, and flexibility PA were an indication of their corresponding health-related PF standard.

A Stimulus Control Analysis of Imprinting in a Human-Reared Pigeon

A Stimulus Control Analysis of Imprinting in a Human-Reared Pigeon

Date: August 2011
Creator: Varnon, Christopher A.
Description: Events that occur early in the life of birds greatly influence social and sexual preferences throughout the course of life. Traditionally, this is explained by a learning process known as imprinting. Young birds are thought to imprint to early stimuli, causing the development of permanent preferences for those stimuli. In the present study, imprinting is examined with respect to behaviors of an adult human-reared pigeon in several conditions. The subject was either presented with no stimulus, a conspecific stimulus, a novel stimulus, a human stimulus, or the human and novel stimuli simultaneously. Several phases within these conditions were employed to pinpoint the variables that produced the most social and sexual behavior. The results showed that while some conditions produced unclear behavior, other conditions produced very clear indications of sexual preference for humans and fear of conspecifics. The results suggest that the concept of imprinting may not be needed to explain the sexual preference of the subject, and that operant contingencies may play a large role in sexual behavior.
