Multi Agent System Based Fault Location In A Smart Microgrid System, Seetaram Alwala

Graduate Theses, Dissertations, and Problem Reports (ETD)

The electric power grid is inherently a huge network that has been going through a lot of transformation because of its restructuring and increase in the deployment of Distributed Generation. The steep increase in electricity demand and the large financial losses caused by the blackouts has initiated research towards increasing the security and robustness of the electric grid and making it a Smart Grid. Smart Grids might incorporate MicroGrids, which can be defined as low to medium voltage networks that contain aggregation of certain loads and Distribution Generation units that can operate in either grid-connected or islanded mode. One of …

Teacher Professional Standards, Accountability, And Ideology: Alternative Discourses, Katarina Tuinamuana

Australian Journal of Teacher Education

Teacher professional standards and accountability are today writ large on the landscape of both schooling and teacher education practice around the world. This paper explores some of the related debates through a discussion of four discourses on teacher professional standards: namely, discourses of commonsense, professionalism and quality, managerialism/performativity, and strategic manoeuvring. It is argued that each of these discourses legitimises particular understandings of standards and quality, illustrating the competing set of lenses through which they are viewed, as well as the broader ideologies from which they emerge, including neoliberalism and technical rationality. These discourses also represent the interpretive practice that …

Putting Partnership At The Centre Of Teachers' Professional Learning In Rural And Regional Contexts: Evidence From Case Study Projects In Tasmania, Sue Stack, Kim Beswick, Natalie Brown, Helen Bound, John Kenny, Joan Abbott-Chapman

Australian Journal of Teacher Education

This paper presents a professional learning (PL) model that emerged from the authors’ involvement with PL processes in several rural and remote schools in the state of Tasmania. As is the case for rural areas generally, young people in rural areas of Tasmania have lower retention rates to Year 12 and lower participation rates in higher education than their urban peers. Schools in these regions typically have less experienced staff, higher staff turnover and reduced access to professional networks compared with urban schools. Four case studies are presented to illustrate the experiences that lead to the partnership model of PL …

Putting ‘Maori’ In The Mainstream: Student Teachers' Reflections Of A Culturally Relevant Pedogogy, Steven S. Sexton

Australian Journal of Teacher Education

This paper reports on student teachers experiences of an education program that was explicitly designed to be grounded in both Kaupapa Māori and mainstream pedagogy. This program started from the Kaupapa Māori view to be Māori as Māori. This was then supported by mainstream epistemology of New Zealand focused good teaching practice. A Kaupapa Māori approach was taken in this qualitative study that used participant driven spiral discourse. The paper suggests that this combined Kaupapa Māori and mainstream approach allowed these student teachers to find their place in education. Conclusions suggest that a culturally relevant pedagogy modeled as good teaching …

But only three predictors …

Improvement Of Data Integrity Using Different Encryption Algorithms, Serwan Waleed

Iraqi Journal of Computers, Communications, Control and Systems Engineering

Web services send and receive messages over standard Internet protocols such as HTTP. Plaintext messages can be intercepted by an attacker and potentially viewed or even modified for malicious purposes. By using message protection, we can protect sensitive data against threats such as eavesdropping and data tampering. Sensitive data transmitted over the Internet should always be encrypted to avoid potential intruders from eavesdropping on the communication anywhere along the route the data takes between the two machines. In this paper, we provide a feasible solution to enhance the integrity of sensitive data. Our approach is to use variant encryption algorithms …

Low Density Parity Check (Ldpc) Codes For A Proposed Slantlet Transform Ofdm System In A Rayleigh Fading Channels With Perfect And Pilot Channel Estimation For M_Ary Psk Modulation, Ghanim Abd Al-Kareem

Iraqi Journal of Computers, Communications, Control and Systems Engineering

Orthogonal Frequency Division Multiplexing (OFDM) is a very attractive technique for high bit rate data transmission in a multipath fading environment that causes intersymbol interference (ISI). In this paper, two steps are used to improve the error rate performance of OFDM system. First, we proposed the Slantlet Transform (SLT) used instead of Fast Fourier Transform (FFT) to obtain high orthogonality properties between subcarriers and hence reduce (ISI). Second, we proposed the Low Density Parity Check (LDPC) Codes for the proposed SLT-OFDM system to improve the Bit Error Rate (BER) and Packet Error Rate(PER) performance. The goal of the proposed SLT …

Trafficking Of Women In Nepal: An Intersectional Analysis Of Organizational Narratives, Bhavana Mahat

Graduate Theses and Dissertations

In Nepal, sex trafficking is usually associated with poverty, illiteracy and gender discrimination. To better understand the discursive dimensions of sex trafficking, this research examines the organizational narratives of the Nepalese anti-trafficking workers using the analytical framework of intersectionality. This study finds that the anti-trafficking workers' organizational narratives are influenced by both personal and institutional narratives. In their personal narratives, anti-trafficking workers recognize the multiple forms of discrimination shaping the victims' experiences, but the intersectional discriminations are rarely addressed in the anti-trafficking programs or services implemented by the non-profit organizations. After having identified sex-trafficking victims as experiencing discrimination based on …

Design Of An 866 Mhz On-Chip Frequency Synthesizer, Phaniraj Joshi

Graduate Theses and Dissertations

There is a strong need for stable frequency references with large tuning ranges in today's communication systems. While the crystal oscillators assure good frequency stability, it is not possible to achieve a large frequency range by tuning the passive components attached to them. Frequency synthesizers are usually used for this purpose because of their ability to produce a variety of output frequencies. The Phase Locked Loop (PLL) based frequency synthesizer is the most preferred of all types of synthesizers available because of its additional features like programmability, low noise and low cost as well as high accuracy and stability. The …

Single Mothers In College: The Effect Of Selected Variables, Rickey Booker

Graduate Theses and Dissertations

Single parent mothers who are currently in poverty may find it difficult to find routes out of poverty and/or even to enrolling in college. Little empirical research has been conducted on low-income single parent mothers who attempt to enroll, persist and graduate college. The current research has shown that single parents are at a high risk of dropping out of college because of many barriers including poverty related issues. This study examined women who had at least one child or dependent, were in poverty, and were first time beginners in college. The purpose for conducting this study was to identify …

A Nietzschean Account Of Human Flourishing: Affirming The Will To Power Inside The Contours Of Friendship, Christian Joshua Roos

Graduate Theses and Dissertations

In this dissertation, I examine Friedrich Nietzsche's notion of the will to power, his account of friendship and his understanding of human flourishing. Through textual analysis, I offer a new way of interpreting the will to power, as the achieving of self-realization. The process of achieving self-realization is undergirded by the satisfaction of seven existential needs that are rooted in the paradoxical human conflict between instincts and consciousness. The existential needs are the need for a frame of orientation, the need for devotion, the need for unity, the need for rootedness, the need for stimulation, the need for effectiveness and …

Creativity In Triadic Supervision: Using Mandalas To Impact The Working Alliance, Kelly Agnes Dunbar

Graduate Theses and Dissertations

This qualitative study investigated the use of mandalas as a creative approach with the potential to impact the supervisory working alliance within the context of triadic supervision. Participants (n=7) included master's level counselors-in-Training (CITs), all female, and ranging in age from 23 to 44. Data generated by the formal interviews gained support for using mandalas as a creative approach in triadic supervision as they revealed the potential to impact the working alliance and the goals, task, and bond therein. Of further importance was the finding that the bond between paired CITs in triadic supervision sessions was also impacted by the …

Determination Of Poultry Litter's Nitrogen-Fertilizer Value For Winter Wheat Production, Brett Lee Gordon

Graduate Theses and Dissertations

Nitrogen (N) availability in poultry litter (PL) applied in the fall as a nutrient source for winter wheat (Triticum aestivum L.) has not been adequately characterized. Our objective was to determine a potentially available N (PAN) coefficient based on the inorganic-N fertilizer equivalence (FEQ) of fall-applied PL to winter wheat via field and laboratory research. Wheat grown at six site-years received 0, 84 and 168 kg N ha-1 as PL applied preplant and/or at-planting. The FEQ of PL-N was based on growth and yield responses of wheat fertilized with 22 to 191 kg N ha-1 applied in late winter as …

Space Makers Or Space Cadets Exploring Children's Perceptions Of Space And Place In The Context Of A Dublin Primary School, A Loxley, B O'Leary, Sj Minton

School of Psychology

This paper discusses two interconnected themes: (1) the variegated role of space in primary school architecture; and (2), the perception of this space as a lived phenomenon from the perspective of pupils. In this context, space is not seen as being synonymous with the physical properties of a school (although this does exert an influence), but as an 'active ingredient' through which a particular social order is produced and sustained. Echoing the work of Lefebvre's (1991) triadic conceptualisation of space, Markus's (1993) meshing of architecture and power (via Foucault, 1991a, 1991b), certain extensions of ecological/ecosystemic theories of child and adolescent …

An Examination Of Teacher Instruction And Student Engagement Involving Adolescents With And Without Challenging Behavior., Regina Gilkey Hirn

Electronic Theses and Dissertations

The interactions between teachers and students provide a venue for instructional delivery and ultimately student achievement in the school setting. However, not all students experience positive interactions with teachers in the typical classroom setting, especially those students exhibiting behavioral challenges. These students are observed with greater off task behavior and increased classroom disruptions when compared with their peers. This dissertation examined teacher and student behavior observed in a typical high school classroom exemplifying these interactions. Direct observations of students and teachers were conducted to answer several research questions addressing teacher behaviors: classroom instruction, opportunities to respond, and feedback to students …

Using Principal Component Analysis For Early Fault Detection In Louisville Water Distribution System., Kevin M. Kastensmidt

Electronic Theses and Dissertations

This research dealt with the examination of Supervisory Control and Data Acquisition (SCADA) information of a water distribution system through Principal Component Analysis (PCA). PCA is a mathematical method to convert a set of possibly correlated data into a set of fewer variables called principal components. In a SCADA environment, possibly hundreds of data points such as booster pumps, storage tanks, pressure reducing valves, and others constantly provide operational statistics including water pressure, tank capacity, and more. This vast amount of data can be difficult to analyze in its entirety, especially to detect issues in the distribution system. PCA was …

Optimal Charging Scheduling For Battery Electric Vehicles Under Smart Grid., Nur Dayana Abd Rahman

Electronic Theses and Dissertations

A projected high penetration of battery electric vehicles (BEV s) in the market will introduce an additional load in the electricity grid. Furthermore, uncontrolled BEV charging from residential users will exacerbate the existing peak load during evening hours. In this thesis, we propose two optimization models to alleviate the impact of extra demand from electric vehicles on the power grid. The first is a centralized charging scheduling model that coordinates the charging among BEV users under the goal of minimizing the total electricity cost for all users. The second model uses a decentralized agent-based approach to scheduling the BEV charging. …

Examining Teachers' Perceptions Of Psychological Gender And Leadership Behavior Of Principals In Public Elementary Schools., Brittany D. Carpenter

Electronic Theses and Dissertations

Research has shown that various leadership styles have different impacts on leader outcomes such as satisfaction, extra effort, and effectiveness. Specifically, researchers have found that transformational leadership positively impacts follower perceptions of satisfaction, extra effort, and leader effectiveness (Avolio, Bass, & lung, 1995; Philbin, 1997; Yammarino, Spangler, & Bass, 1993). However, research has shown that not all leaders display transformational leadership. In fact, Eagly, Karau, & lohnson (1992) and their colleagues have shown transformational leadership in education to be linked to the extent to which male and female principals carry out their gender roles - referring to role congruity. Currently, …

Aquatic Plant Surveys In The Bureau Of Land Management, Medford District, 2010-2011, Mark D. Sytsma, Rich Miller, Vanessa Morgan

Center for Lakes and Reservoirs Publications and Presentations

The introduction of invasive aquatic plant species (IAPS) can cause significant ecological and economic harm. IAPS can displace native aquatic plant species, impair recreation, and degrade water quality. Early detection of new invasions can improve chances for successful eradication or containment to reduce the risk of IAPS spread. The Oregon Department of Agriculture (ODA) lists the most egregious offenders as “Noxious Weeds” which are defined as plants classified by the Oregon State Weed Board that are injurious to public health, agriculture, recreation, wildlife, or any public or private property (ODA 2011).

Several IAPS classified as noxious have been detected within …

Common Crowd Dynamics: Shaping Behavioral Intention Models, Marcel Bouchard

Theses

As the human population grows, so too does the need to understand human behavior. One particularly important aspect of human behavior is how it changes within conglomerations of people, i.e. crowds. In this thesis, a method for modeling crowd behavior is proposed. This method draws inspiration from the concept of behavioral intention and the related forces of attitudes, influences, and social norms. These topics are first defined and detailed, followed by a survey of related research. Next, the model is presented and adapted to three common crowd dynamics, each stressing a different component of behavioral intention. Observations are made about …
