Exploring Analog and Digital Design Using the Open-Source Electric VLSI Design System

Exploring Analog and Digital Design Using the Open-Source Electric VLSI Design System

Date: May 2016
Creator: Aluru, Gunasekhar
Description: The design of VLSI electronic circuits can be achieved at many different abstraction levels starting from system behavior to the most detailed, physical layout level. As the number of transistors in VLSI circuits is increasing, the complexity of the design is also increasing, and it is now beyond human ability to manage. Hence CAD (Computer Aided design) or EDA (Electronic Design Automation) tools are involved in the design. EDA or CAD tools automate the design, verification and testing of these VLSI circuits. In today’s market, there are many EDA tools available. However, they are very expensive and require high-performance platforms. One of the key challenges today is to select appropriate CAD or EDA tools which are open-source for academic purposes. This thesis provides a detailed examination of an open-source EDA tool called Electric VLSI Design system. An excellent and efficient CAD tool useful for students and teachers to implement ideas by modifying the source code, Electric fulfills these requirements. This thesis' primary objective is to explain the Electric software features and architecture and to provide various digital and analog designs that are implemented by this software for educational purposes. Since the choice of an EDA tool is based on the ...

Exploring Aspects of Korean Traditional Music in Young Jo Lee's Piano Honza Nori

Exploring Aspects of Korean Traditional Music in Young Jo Lee's Piano Honza Nori

Date: August 2013
Creator: Kim, Jin
Description: Since the 1960s, several gifted Korean composers, including perhaps most notably Young Jo Lee (b. 1943), have been internationally acclaimed for their work. In Western countries, however, there has been a scarcity of academic studies examining the artistry of the music of these Korean composers. Nonetheless, as one of today's most recognized composers in Korea, Young Jo Lee has been invited to numerous international concerts, conferences, and festivals where his works have been played and discussed. A salient feature of his compositions is the fusion of Korean traditional music and the elements of Western compositions, such as in, for one distinctive example, his piano composition, Piano Honza Nori. This musical study describes and analyzes how Lee integrates Korean traditional elements with Western musical ideas in Piano Honza Nori. Results of this study will contribute to the limited literature on the analysis of contemporary piano composition that integrates Korean traditional elements.

Exploring Critical Factors in Predicting Post-Adoptive Use of Facebook

Exploring Critical Factors in Predicting Post-Adoptive Use of Facebook

Date: May 2011
Creator: Magro, Michael J.
Description: Social networking applications (SNAs) have experienced a boom in popularity in recent years. Sites like Facebook and MySpace continuously draw new users, and are successful in organizing groups of users around topics of common interest. Among SNAs, Facebook has demonstrably outgrown its rivals growing an estimated 157 percent from 2008 to 2009. Facebook is now estimated to be the fourth largest Internet site in the world, trailing only Google, Microsoft and Yahoo (Schonfeld 2009). This dissertation posits and tests a theoretical model composed of key factors that contribute to post-adoptive use of social networking applications and the relationship of those factors to one another. This study also identifies and clarifies new constructs that were not previously used to measure usage, and further refines the constructs that were previously used so that they better fit social networking applications. The results of this dissertation show that the critical factors of social capital, hedonic enjoyment, perceived usefulness, social influence, satisfaction and attitude have a positive influence on a post-adoptive user's intention to continue using Facebook. The results of this study yielded a structural model for predicting the post-adoptive use of Facebook. This work also developed an instrument for measuring constructs relevant to social ...

Exploring Factors That Lead to Perceived Instructional Immediacy in Online Learning Environments

Exploring Factors That Lead to Perceived Instructional Immediacy in Online Learning Environments

Date: December 2014
Creator: Spiker, Chance W.
Description: Instructional communication research clearly indicates that instructor immediacy contributes significantly to effective instruction. However, the majority of immediacy studies have been conducted in traditional (face-to-face) classroom environments. More recently, instructional communication research has focused on assessing the impact of immediacy in online classroom environments. Again, immediacy appears to significantly contribute to effective instruction. The challenge is that most recent immediacy studies use immediacy measurements developed to test immediacy behaviors in face-to-face settings. Considering the lack of nonverbal communication and limited or absent synchronous or verbal communication in online instructional settings, the behaviors contributing most significantly to perceived immediacy, researchers need to reassess the immediacy construct in online environments. The present research explores and identifies behaviors reported by instructors to establish psychological closeness (i.e., immediacy) in online learning environments and assesses to what extent these behaviors are similar to or different from face-to-face immediacy-producing behaviors.

Exploring Fear and Freud's The Uncanny

Exploring Fear and Freud's The Uncanny

Date: May 2007
Creator: Grizzle, Eric
Description: Fear is one of the oldest and most basic of human emotions. In this thesis, I will explore the topic of fear in relation to literature, both a staple of the horror genre as well as a device in literary works, as well as in my own writings. In addition, I will use Sigmund Freud's theory of the “uncanny” as a possible device to examine the complexities of fear and its effects both on the mind and body through the medium of literature, and, more specifically, where and how these notions are used within my own short stories. By exploring how and why certain fears are generated, we may be able to better examine our own reactions in this regard.

Exploring flow among Division I and intramural athletes.

Exploring flow among Division I and intramural athletes.

Date: May 2004
Creator: Peterson, Ryan J.
Description: This study explores the flow experiences of collegiate athletes. NCAA Division I athletes and intramural athletes (N = 180) completed a series of measures on their flow experiences. Comparisons were made regarding the characteristics of flow, the perceived facilitators of flow, the frequency of flow experiences, and explored the role of perceived ability. Using a person by situation interaction framework, this study singles out perceived ability as a person factor and competitive level as a situational factor to more clearly examine flow experiences. Results indicated distinctions between the two groups. Mainly, the intramural athletes reported experiencing the merging of action and awareness, autotelic experience, transformation of time and having clear goals more frequently than the NCAA Division I athletes. No group differences were found for flow frequency or flow facilitators. Perceived ability was found to have a weak, but significant relationship with specific flow facilitators and characteristics.

Exploring Fundamental Principles in the Study of Derived Relational Responding in Pigeons

Date: August 2013
Creator: Hinnenkamp, Jay Evan
Description: A persistent challenge for behaviorally-based accounts of learning has been providing an account of learning that occurs in the absence of systematically programmed contingencies of reinforcement. Symmetry, one type of emergent behavior, has been repeatedly demonstrated with humans, but has been considerably more difficult to demonstrate with non-humans. In this study, pigeons were exposed to a go/no-go procedure in which hue stimuli were presented full screen on a touchscreen monitor. Pigeons learned 12 baseline relations in less than 30 days. Traditional measures used to evaluate symmetry indicated that, during tests, three of the four birds responded more to the reverse of relations that were reinforced in training than to the reverse of relations that were not reinforced in training. However, additional analyses of these data suggests that these differences were driven by one of two trial types and that symmetry was only observed for one of the two predicted relations. These data systematically replicate and extend work by Urcuioli and colleagues and point to areas where further research is needed.

Exploring General Education Pre-service Teachers’ Levels of Concern Regarding the Implementation of Response to Intervention

Exploring General Education Pre-service Teachers’ Levels of Concern Regarding the Implementation of Response to Intervention

Date: August 2013
Creator: Barrio Renteria, Brenda Leticia
Description: Schools are increasingly challenged to respond to educational initiatives, implement accountability measures, and incorporate standards-driven curriculum changes introduced by laws such as the Individuals with Disabilities Education Improvement Act (IDEIA) of 2004. IDEIA signified a shift in the field of education and intensified practitioners’ concerns about the identification and instruction of students with learning disabilities (LD). The revisions to IDEIA proposed alternative models for the evaluation and identification of students with LD, such as response to intervention (RTI). RTI is an educational framework that supports students at-risk for academic failure by focusing on preventative measures. As teachers’ roles evolve in response to innovations such as RTI, teacher preparation programs must adjust their focus and curriculum accordingly. A parallel mixed-methods design was used to explore 100 general education pre-service teachers’ levels of concern regarding the implementation of RTI based on the concerns based adoption model. The sample for the study integrated general education pre-service teachers enrolled in professional development schools (PDS) at two levels of candidacy, PDS1 and PDS2. Data collected was analyzed utilizing canonical correlation analysis (CCA), multivariate analysis of variance (MANOVA), descriptive statistics, and thematic analysis. Results explain general education pre-service teachers’ levels of knowledge had a negative relationship ...

Creator: Willis II, Roderick C.
Description: In accordance with the Texas Higher Education Coordinating Boards’ Closing the Gaps by 2015, this research study analyzed self-reported perceptions about college-going culture from students (n = 151) who attended four House Bill 400 schools serving Latino and African American communities in the Dallas-Fort Worth Metroplex. This study utilized exploratory factor analysis (EFA) with a maximum likelihood extraction technique to identify hidden perceptions (latent factors) that account for common variance among student perceptions about college-going culture. The study also tested the validity and inter-item reliability of the 15-item College-Going Culture Survey used in data collection. The parallel analysis, EFA, and Cronbach’s ? identified two latent factors of Verified College Potential (? = .70) and College Capital Awareness (? = .71) that, together, explained 40.1% of students’ perceptions. The two factors were non-significantly negatively correlated (r = -.495, p = .354). By utilizing the two latent constructs, a 10-item revised College-Going Culture Survey is recommended to improve the inter-item reliability coefficient from ? = .46 to ? = .77. Descriptive statistics revealed that Latino and African-American students affirmed aspects of the college-going culture at HB 400 schools. However, latent factors suggest the possibility that students who reportedly feel most encouraged to ...

Exploring Inorganic Catalysis with Electronic Structure Simulations

Access: Use of this item is restricted to the UNT Community.
Date: May 2016
Creator: Karbalaei Khani, Sarah
Description: Organometallic catalysis has attracted significant interest from both industry and academia due to its wide applications in organic synthetic transformations. Example of such transformations include the reaction of a zinc carbenoid with olefins to form cyclopropanes. The first project is a computational study using both density functional and correlated wavefunction methods of the reaction between ethylene and model zinc carbenoid, nitrenoid and oxenoid complexes (L-Zn-E-X, E = CH2, NH or O, L = X = I or Cl). It was shown that cyclopropanation of ethylene with IZnCH2I and aziridination of ethylene with IZnNHI proceed via a single-step mechanism with an asynchronous transition state. The reaction barrier for the aziridination with IZnNHI is lower than that of cyclopropanation. Changing the leaving group of IZnNHI from I to Cl, changes the mechanism of the aziridination reaction to a two-step pathway. The calculation results from the epoxidation with IZnOI and ClZnOCl oxenoids suggest a two-step mechanism for both oxenoids. Another important example of organometallic catalysis is the formation of alkyl arenes from arenes and olefins using transition metal catalysis (olefin hydroarylation). We studied with DFT methods the mechanism of a novel Rh catalyst (FlDAB)Rh(TFA)(η2–C2H4) [FlDAB = N,N’ -bis(pentafluorophenyl)-2,3-dimethyl-1,4-diaza-1,3-butadiene; TFA = trifluoroacetate] that converts ...

Exploring job related stress and job satisfaction in a modern law enforcement communications division.

Exploring job related stress and job satisfaction in a modern law enforcement communications division.

Date: May 2005
Creator: Burgess, Lavona
Description: One of the most neglected areas of criminological and social science research is the police communications or dispatch center. While research projects dealing with stress and job satisfaction are found in abundance for other occupations, studies specific to the police dispatcher are uncommon. The role of the dispatcher has changed significantly in the last few decades. Improvements in technology and changes in public expectations of emergency services have forever altered the communications professional. Dispatchers work in an environment reliant on information. There is tremendous pressure to process the information coming into a communications center quickly and correctly. A mistake could prove fatal. Work pressures, burnout, high employee turnover, low pay, and a lack of respect from police coworkers can easily result in negative emotional and psychological consequences for the dispatcher. An effective manager could reduce the feelings of stress and low job satisfaction this environment can facilitate. The current study utilizes survey data from a sample of police dispatchers and their managers in the Dallas/Fort Worth, Texas area. The purpose of the survey is to identify the level of stress and job satisfaction reported by the dispatchers and their managers. The effects of differing types of stress will be investigated. ...

Exploring Lifestyle Orientation, Attitudes Toward Lifestyle Merchandising, and Attitudes Toward Lifestyle Advertising as Predictors of Behavioral Intention to Purchase Lifestyle Home Furnishing Products

Exploring Lifestyle Orientation, Attitudes Toward Lifestyle Merchandising, and Attitudes Toward Lifestyle Advertising as Predictors of Behavioral Intention to Purchase Lifestyle Home Furnishing Products

Date: May 2005
Creator: Wilbanks, Jennifer Kay
Description: A number of lifestyle merchandising and advertising strategies are being used in the home furnishings industry. However, there is limited research regarding the effectiveness of these strategies. The purpose of this study was to explore consumers' attitudes toward the lifestyle concept. Analyses of several consumer behavior variables and descriptors offered noteworthy findings for the home furnishings industry. This study found that although lifestyle orientation is a valuable tool for delineating consumer markets, these segmentations were not significant determinates of consumers' preference for elements of the lifestyle construct. Retailers and manufacturers are not simply creating home furnishing collections that target the needs of specific psychographic segment, but rather creating lifestyles being aspired to obtain. Although respondents scored the attitude variables neutral, the current market environment offers many examples of successfully home furnishing implementations of the lifestyle concept. These success stories coupled with additional findings indicate consumers' positive response to lifestyle merchandising.

Creator: Gautam, Mahesh
Description: With conventional CMOS technologies approaching their scaling limits, researchers are actively investigating alternative technologies for ever increasing computing and mobile demand. A number of different technologies are currently being studied by different research groups. In the last decade, one-dimensional (1D) carbon nanotubes (CNT), graphene, which is a two-dimensional (2D) natural occurring carbon rolled in tubular form, and zero-dimensional (0D) fullerenes have been the subject of intensive research. In 2008, HP Labs announced a ground-breaking fabrication of memristors, the fourth fundamental element postulated by Chua at the University of California, Berkeley in 1971. In the last few years, the memristor has gained a lot of attention from the research community. In-depth studies of the memristor and its analog behavior have convinced the community that it has the potential in future nano-architectures for optimization of high-density memory and neuromorphic computing architectures. The objective of this thesis is to explore memristors for analog and mixed-signal system design using Simscape. This thesis presents a memristor model in the Simscape language. Simscape has been used as it has the potential for modeling large systems. A memristor based programmable oscillator is also presented with simulation results and characterization. In addition, simulation results of different memristor models ...

Exploring Naming Behavior in Personal Digital Image Collections: the Iconology and Language Games of Pinterest

Exploring Naming Behavior in Personal Digital Image Collections: the Iconology and Language Games of Pinterest

Date: December 2014
Creator: Sutcliffe, Tami
Description: As non-institutional digital image collections expand into social media, independent non-professional image curators are emerging, actively constructing alternative naming conventions to suit their needs in a social collecting environment. This project considers how independent user-curators are developing particular sense-making behaviors as they actively contribute names to large, unstructured social image collections. In order to capture and explore this evolving language adaptation, Pinterest names are analyzed using a matrix composed of Panofsky’s three strata of subject matter, Rosch’s levels of categorical abstraction, Shatford Layne’s image attributes and Wittgenstein’s language game constructions. Analyzing Pinterest image names illuminates previously unnoticed behaviors by independent user-curators as they create shared collections. Exploring the various language choices which user-curators select as they apply this new curating vocabulary helps identify underlying user needs not apparent in traditionally curated collections restricted to traditional naming conventions.

Exploring Privacy in Location-based Services Using Cryptographic Protocols

Exploring Privacy in Location-based Services Using Cryptographic Protocols

Date: May 2011
Creator: Vishwanathan, Roopa
Description: Location-based services (LBS) are available on a variety of mobile platforms like cell phones, PDA's, etc. and an increasing number of users subscribe to and use these services. Two of the popular models of information flow in LBS are the client-server model and the peer-to-peer model, in both of which, existing approaches do not always provide privacy for all parties concerned. In this work, I study the feasibility of applying cryptographic protocols to design privacy-preserving solutions for LBS from an experimental and theoretical standpoint. In the client-server model, I construct a two-phase framework for processing nearest neighbor queries using combinations of cryptographic protocols such as oblivious transfer and private information retrieval. In the peer-to-peer model, I present privacy preserving solutions for processing group nearest neighbor queries in the semi-honest and dishonest adversarial models. I apply concepts from secure multi-party computation to realize our constructions and also leverage the capabilities of trusted computing technology, specifically TPM chips. My solution for the dishonest adversarial model is also of independent cryptographic interest. I prove my constructions secure under standard cryptographic assumptions and design experiments for testing the feasibility or practicability of our constructions and benchmark key operations. My experiments show that the proposed ...

Exploring Process-Variation Tolerant Design of Nanoscale Sense Amplifier Circuits

Exploring Process-Variation Tolerant Design of Nanoscale Sense Amplifier Circuits

Date: December 2010
Creator: Okobiah, Oghenekarho
Description: Sense amplifiers are important circuit components of a dynamic random access memory (DRAM), which forms the main memory of digital computers. The ability of the sense amplifier to detect and amplify voltage signals to correctly interpret data in DRAM cells cannot be understated. The sense amplifier plays a significant role in the overall speed of the DRAM. Sense amplifiers require matched transistors for optimal performance. Hence, the effects of mismatch through process variations must be minimized. This thesis presents a research which leads to optimal nanoscale CMOS sense amplifiers by incorporating the effects of process variation early in the design process. The effects of process variation on the performance of a standard voltage sense amplifier, which is used in conventional DRAMs, is studied. Parametric analysis is performed through circuit simulations to investigate which parameters have the most impact on the performance of the sense amplifier. The figures-of-merit (FoMs) used to characterize the circuit are the precharge time, power dissipation, sense delay and sense margin. Statistical analysis is also performed to study the impact of process variations on each FoM. By analyzing the results from the statistical study, a method is presented to select parameter values that minimize the effects of ...

Creator: Bewsey, Kyle
Description: This study explored psychopathic personality traits among a non-criminal, college undergraduate sample. Much research has been done on conceptualizing the construct of psychopathy, but this work has been conducted primarily with incarcerated individuals using a structured interview, The Psychopathy Checklist – Revised (PCL-R; Hare, 1991, 2003). The goal of the current study was to assess psychopathic traits among non-criminal individuals using The Self-Report Psychopathy Scale - Version Four (SRP-IV; Paulhus, Neumann, & Hare, in press), and compare how SRP-IV scores were associated with a well recognized semi-structured interview for psychopathy, The Psychopathy Checklist – Screening Version (PCL: SV; Hart, Cox, & Hare, 1995). The study also examined whether psychopathic personality traits could be predicted using a measure of normal-range personality, based on the five-factor model (FFM; Digman, 1990), and a measure developed by Loevinger (1976) related to ego development. Five-Factor Model Rating Form (FFMRF; Mullins-Sweat, Jamerson, Samuel, Olson, & Widiger, 2006) scores and Total Protocol Ratings (TPR score) on the Washington University Sentence Completion Test (WUSCT; Hy & Loevinger, 1996) were used to predict psychopathy scores. Correlations of SRP-IV scores and PCL: SV scores with FFMRF scores and WUSCT TPR scores were also examined for their uniformity. As predicted, there ...

Description: This study related college students' remembered early relationships with parents to their depression symptoms and to dependent and self-critical subjective feelings. Undergraduates (N = 217, 118 female, 99 male) provided information regarding their current level of depression, overall functioning, subjective feelings of depression (Depressive Experiences Questionnaire), negative thoughts, interpersonal functioning, and recollections of their parents' behavior and attitudes. Depression symptoms were related to dependent and self-critical feelings and to recalled low parental care and high parental control. However, for women, paternal affection and, for men, paternal control, were unrelated to depression symptoms. Other results are inconclusive but, overall, provide evidence for the usefulness of Blatt's theory in assessing depression via dependent and self-critical subjective feelings.

Creator: Angnakoon, Putthachat
Description: The changing landscape of demographics, technology, and diversity in the learning environment is challenging schools around the world to rethink their approaches to the implementation of high-quality teaching practices. Classroom practices are becoming more complex because educators have to ensure that their students are well-equipped with 21st century skills (e.g., Darling-Hammond, 2010; Dede, 2010; Griffin, McGaw, & Care, 2012). Educators, curriculum developers, and school administrators need to be more than experts in pedagogy. They are now required to keep up with current ideas, innovative instructional practices, and the results of a variety of educational reform efforts. Believing that teachers’ beliefs are the most important psychological construct with regard to instructional practices (Pajares, 1992) and that teachers’ beliefs are related to their choice of classroom practices and, ultimately, the students’ performance (Bybee, Taylor, Gardner, Van Scotter, Powell, Westbrook, & Landes, 2006; Staub & Stern, 2002), the author of this study utilizes the international data set of the Teaching and Learning International Study (TALIS) 2013 to examine the associations between teachers’ constructivist beliefs, their self-efficacy beliefs, professional activities, and the school principals’ instructional leadership as related to lower secondary school teachers and principals in South Korea, Finland, and Mexico.

Creator: Lopez, Nicolette P.
Description: Encouraging positive work team growth depends on, in part, the form and availability of organizational resources and support. Support systems have been found to be important for work team health and survival. However, managers are challenged to make resource decisions while working within company budgetary restraints. Previous research has indicated a positive relationship exists between teams provided with appropriate resources and support, and increased team performance. This study extended previous research by exploring if team performance can predict resources and support. Specifically, the means by which managers allocate resources based on team performance was examined. Archival data included 36 work teams and their managers drawn from four geographically dispersed manufacturing companies. Information gathered from a modified version of an original team support system instrument was used to assess the importance and presence of four resource systems. Additionally, a gap score was calculated from these scores to assess the alignment between resource need and resource existence. Data was used to assess the potential relationships between managers' perceptions of team performance and the manner by which resources are allocated. All hypotheses produced non-significant findings. Results of the hypotheses, data patterns, and limitations of the study are discussed, and opportunities for future research ...

Description: The purpose of this research was to conduct case studies to explore and describe Thai university students' awareness and application of cognitive and metacognitive strategies when reading and writing in English-as-a-foreign-language (EFL). Four participants, including two high and two low English language proficiency learners, were selected from 14 students enrolled in a five-week course called English for Social Sciences offered at Kasetsart University in Bangkok, Thailand in 2005. The major sources of data for the analyses included the transcripts of the participants' pair discussions, think-aloud protocols, interviews, and daily journal entries. In addition, field work observations, reading and writing strategy checklists, participants' written work, and the comparison of the pretest and posttest results were also instrumental to the analyses. The interpretive approach of content analysis was employed for these four case studies. Findings were initially derived from the single-case analyses, and then from cross-case analyses. Major findings revealed that strategic knowledge enhanced these English-as-a-foreign- language (EFL) learners' proficiency in English reading and writing. However, applying elaborative strategies for higher-level reading was challenging for most of the participants. Two crucial factors that impeded their development were the learners' uncertain procedural and conditional knowledge of strategy uses and their limited English language ...
