Hybrid Fuzzy-Pid Controller For Buck-Boost Converter In Solar Energy-Battery Systems, Karime Farhood Hussein

Masters Theses

In the present work, we propose a hybrid fuzzy PID control system to prevent overshoot and oscillations in DC-DC buck-boost converter for solar-battery system. We design and simulate a PID, a Fuzzy logic controller, and hybrid fuzzy PID control system to stabilize the output voltage of the buck-boost converter. The performance results using dynamic response of all of these controllers in terms of rise time, overshoot, peak time, and voltage oscillation are presented. The simulation results support the validity and advantages of the hybrid method.

Children’s Spanish-language books from bookstores and public libraries were analyzed to determine the presence of features that might facilitate print awareness, phonological awareness, and …

Reading Intervention Strategies For General Education Middle School Students: Providing A Space For Teachers To Share Effective Methods, Amy Michelle Baas

Masters Theses

While studies have been conducted to highlight intervention strategies that will help struggling readers, very few of these empirical studies have used middle school aged students as participants. And among those studies which have, the results were based solely on quantifiable data; the opinions of the classroom teachers who work with these students daily cannot be found in these or any of the empirical studies. The purpose of this thesis is to fill this gap by offering a space for middle school English language arts teachers to share effective intervention strategies that they use in their classrooms to help struggling …

Accommodating Students With Autism Spectrum Disorder In The Writing Center, Rebekah Barton

Masters Theses

This thesis explores how collegiate writing centers could better serve the needs of students with autism. As there is so little research that involves writing centers and college students with autism, scholarship was pulled from traditional writing center pedagogy, research concerning adults with autism, and the information that was available about teaching students with autism in the college composition classroom. A mixed methods approach was used to conduct my own research: my study involved surveys, interviews, visits, and website analysis. It became clear that not only are writing centers not ready to accommodate students with autism, but some writing center …

Online Diagnosis Of Diabetes With Twitter Data, Farheen Ali

Masters Theses

"Innovation in technology enables people to communicate, share information and look for their needs by just sitting in rooms and going through some clicks. While social media has played a very important role in connecting people worldwide, its potential has stretched beyond the innovative idea of connecting people through their social networks. While many thought there was no meeting point for the healthcare sector and social media, it was a surprise when research and innovations have shown that social media could lay a very significant role in the health care sector.

Research has been done in developing models that could …

Written Discourse Performance After Blast Injury, Brittany M. Loomis

Masters Theses

A blast injury (BI) is caused by a wave from a bomb which damages organs, specifically the brain. Once soldiers/veterans have sustained a BI, they will most likely present with a cognitive-communication deficit resulting from the traumatic brain injury. Language related symptoms are most apparent in written language skills due to the high level of cognitive function required for writing. This study investigated written discourse skills following a BI. Written discourse samples were collected from four participants and four controls. A description of the Butcher Picture from the Aphasia Diagnostic Profile was analyzed for productivity, efficiency, and local and global …

The Effects Of Cued Speech On Phonemic Awareness Skills, Jessica M. Phillips

Masters Theses

Research suggests phonemic awareness is enhanced through multimodality training. Cued Speech is a multimodality system that combines hand signs with mouth movements to represent phonemes of the spoken language. This system has been utilized successfully in developing phonological awareness with children with hearing loss. However, no research is available on its effectiveness with children who are not deaf or hard-of-hearing. The efficacy of the use of Cued Speech for the enhancement of phonological skills in typically developing 1st grade students was evaluated in this study. Twenty-six 1^st graders identified as low-achieving readers by their classroom teachers were administered the …

American Sign Language Alphabet Recognition Using Microsoft Kinect, Cao Dong

Masters Theses

"American Sign Language (ASL) fingerspelling recognition using marker-less vision sensors is a challenging task due to the complexity of ASL signs, self-occlusion of the hand, and limited resolution of the sensors. This thesis describes a new method for ASL fingerspelling recognition using a low-cost vision camera, which is Microsoft's Kinect. A segmented hand configuration is first obtained by using a depth contrast feature based per-pixel classification algorithm. Then, a hierarchical mode-finding method is developed and implemented to localize hand joint positions under kinematic constraints. Finally, a Random Decision Forest (RDF) classifier is built to recognize ASL signs according to the …

The Pagan Pudicitia Of Early Christian Roman Women, Iris Rebecca Petty

Masters Theses

Accessing the everyday experiences of late antique non-elite Roman women in the Latin west is limited by sources and issues of authorship. Interdisciplinary scholarship, however, has opened up new avenues in recent years through which these women’s experiences may be studied. When literary-historical questions are asked of these sources’ authors, audiences, motives and intents, the answers provide insight into the roles women and femininity played in early Christianity. By examining an array of late antique Roman representations of good classical women, a unique continuity is seen in the transition from pagan to Christian Rome. The Latin patristic writers capitalized on …

A Comparison Of Two Variations Of A Stimulus-Stimulus Pairing Procedure On Novel And Infrequent Vocalizations Of Children With Autism, Andrew J. Bulla

Masters Theses

Despite the growth in a behavioral technology for the treatment of autism, a small population of individuals with autism fails to develop functional language. One procedure used for inducing vocalizations in non-verbal children is a stimulus-stimulus pairing (SSP) procedure. In an SSP procedure a vocalization is paired with a reinforcer over a period of time to establish the vocalization as a learned reinforcer, and any utterance of the target vocalization is believed to be automatically reinforced thus increasing the frequency of the vocalization. Past research has yielded mixed results with the SSP procedure, and more research is warranted to identify …

Investigating Teachers’ Self-Reported Efficacy In Instructing Culturally And Linguistically Diverse Learners In Alternative Settings, Liane Kay Lancaster

Masters Theses

Teachers in alternative schools have limited to no knowledge of issues influencing students who are culturally and linguistically different. Current educational research lacks an in-depth examination of teachers’ perceptions of their use of culturally relevant practices with this group.

Using an adaptation of Siwatu’s (2007) Culturally Responsive Teaching Self-Efficacy Scale and drawing upon the theories of constructivism and multiculturalism, this study documents the perceptions of teachers’ preparedness in an alternative high school in the Midwest. The investigator collected information that may assist teachers and teacher preparation institutions in delivering instruction that better suits students who are culturally and linguistically diverse. …

The Social And Cultural Meanings Of Names In Late Antique Italy, 313-604, Eric Ware

Masters Theses

This thesis examines many uses of names in Italian culture and society between the years 313 and 604. Through an anthroponymic study of names in Late Antique Italy, I explore the relationships between names and religion, social groups, gender, and language. I analyze the name patterns statistically and through micro-historical studies. This thesis argues that, contrary to studies emphasizing the late antique decline of the Roman trinominal system, Italian names demonstrated continuity with classical onomastic practices. The correlations between saint’s cults and local names and the decline of pagan names suggests that saints’ names replaced pagan ones as apotropaic names …

Idealism And Pragmatism In The Rhetoric Of John Boehner: A Weaverian Analysis Of Congressional Discourse, Cody Hawley

Masters Theses

American political rhetoric is characterized by a synthesis of contradictory idealistic and pragmatic elements, both of which are necessary if there is to be convincing persuasion. The way in which politicians rhetorically approach this dichotomy is significant, however, current studies on the topic are limited to presidential discourse. There is little research on this topic in other settings such the United States House of Representatives. This criticism analyzes John Boehner's congressional rhetoric in the idealistic-pragmatic dichotomy. The critical method utilized is Richard Weaver's four forms of argument-genus, similitude, consequence, and circumstance. Eight speeches of John Boehner, four from his position …

Scientism, Satire, And Sacrificial Ceremony In Dostoevsky's "Notes From Underground" And C.S. Lewis's "That Hideous Strength", Jonathan Smalt

Masters Theses

Though the nineteenth-century Victorian belief that science alone could provide utopia for man weakened in the epistemological uncertainty of the postmodern era, this belief still continues today. In order to understand our current scientific milieu--and the dangers of propagating scientism--we must first trace the rise of scientism in the nineteenth-century. Though removed, Fyodor Dostoevsky, in Notes From Underground (1864), and C.S. Lewis, in That Hideous Strength (1965), are united in their critiques of scientism as a conceptual framework for human residency. For Dostoevsky, the Crystal Palace of London's Great Exhibition (1862) embodied the nineteenth-century goal to found utopia through the …

Contextualizing Subjectivity: Speaking (Back To) Colonialism In Jamaica Kincaid’S Annie John, Lucy, And A Small Place, Sierra Holmes

Masters Theses

The narrators of Jamaica Kincaid’s Annie John, Lucy, and A Small Place all struggle to form a coherent sense of self while living within the colonial ideology that objectifies them and denies them identities as speaking subjects. In this thesis, Julia Kristeva’s theories of language and subject formation are used to explain why and how the narrators’ subjectivity is limited by colonial discourse. Particular attention is given to the way in which the narrators’ relationships with their mothers both threaten and necessitate their emergence into Kristeva’s symbolic order of language, and therefore into the colonial discourse community. The thesis also …
