The Influence Of Ammonia And Carbon Dioxide On The Sorption Of A Basic Organic Pollutant To A Mineral Surface, Maneerat Ongwandee, Glenn Morrison, S. S. Bettinger

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Indoor surfaces have a sorptive capacity for organic pollutants which may be significantly influenced by other gases and the pH of the surface. in this research, we examine the influence of a common indoor gaseous acid, CO₂, and base, NH₃, on the adsorption of a volatile organic base, trimethylamine (TMA), to a mineral surface, zirconium silicate beads. Varying ammonia and CO₂ within concentration ranges of indoor relevance substantially influences the sorptive capacity of this mineral surface. Increasing the CO₂ mixing ratio to 1000 p.p.m. enhances surface capacity of TMA by 40-50%; increasing the NH3 …

Modal Perturbation Method For The Dynamic Characteristics Of Timoshenko Beams, Meng-Lin Lou, Quihua Duan, Genda Chen

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Timoshenko beams have been widely used in structural and mechanical systems. under dynamic loading, the analytical solution of a Timoshenko beam is often difficult to obtain due to the complexity involved in the equation of motion. In this paper, a modal perturbation method is introduced to approximately determine the dynamic characteristics of a Timoshenko beam. In this approach, the differential equation of motion describing the dynamic behavior of the Timoshenko beam can be transformed into a set of nonlinear algebraic equations. Therefore, the solution process can be simplified significantly for the Timoshenko beam with arbitrary boundaries. Several examples are given …

Decentralized Discrete-Time Neural Network Controller For A Class Of Nonlinear Systems With Unknown Interconnections, Jagannathan Sarangapani

Electrical and Computer Engineering Faculty Research & Creative Works

A novel decentralized neural network (NN) controller in discrete-time is designed for a class of uncertain nonlinear discrete-time systems with unknown interconnections. Neural networks are used to approximate both the uncertain dynamics of the nonlinear systems and the unknown interconnections. Only local signals are needed for the decentralized controller design and the stability of the overall system can be guaranteed using the Lyapunov analysis. Further, controller redesign for the original subsystems is not required when additional subsystems are appended. Simulation results demonstrate the effectiveness of the proposed controller. The NN does not require an offline learning phase and the weights …

Derivation Of A Closed-Form Approximate Expression For The Self-Capacitance Of A Printed Circuit Board Trace, Todd H. Hubing, Hwan-Woo Shim

Electrical and Computer Engineering Faculty Research & Creative Works

The electric fields that couple traces on printed circuit boards to attached cables can generate common-mode currents that result in significant radiated emissions. Previous work has shown that these radiated emissions can be estimated based on the self-capacitances of the microstrip structures on a board . In general, the determination of these self-capacitances must be done numerically using three-dimensional static modeling software. In this paper, an approximate closed-form expression for the self-capacitance of microstrip traces is derived. This expression can be used to estimate the voltage-driven common-mode emissions from boards with various microstrip trace geometries. The expression also provides insight …

Two Separate Continually Online-Trained Neurocontrollers For A Unified Power Flow Controller, Ganesh K. Venayagamoorthy, Radha P. Kalyani

Electrical and Computer Engineering Faculty Research & Creative Works

The crucial factor affecting the modern power systems today is load flow control. The Unified Power Flow Controller (UPFC) provides an effective means for controlling the power flow and improving the transient stability in a power network. The UPFC has fast complex dynamics and its conventional control is based on a linearized model of the power system. This paper presents the design of neurocontrollers to provide better damping during transient and dynamic control. Two separate neurocontrollers are used for controlling the UPFC, one neurocontroller for the shunt inverter and the other for the series inverter. Simulation studies carried out in …

Combining High Conductivity With Complete Optical Transparency: A Band Structure Approach, Julia E. Medvedeva, Arthur J. Freeman

Physics Faculty Research & Creative Works

A comparison of the structural, optical and electronic properties of the recently discovered transparent conducting oxide (TCO), nanoporous Ca12Al14O33, with those of the conventional TCOs (such as Sc-doped CdO) indicates that this material belongs conceptually to a new class of transparent conductors. For this class of materials, we formulate criteria for the successful combination of high electrical conductivity with complete transparency in the visible range and emphasize the significant correlation between their structural characteristics and electronic and optical properties. Our analysis suggests that this set of requirements can be met for a group of novel materials called electrides which may …

Dissertations and Theses @ UNI

This descriptive philosophical study examines 355+ question seeds of thought and discourse on consciousness, communication, education, and technology, much in the contexts of philosophical structures of human beings from 4,000,000 B.C. hominid man to the future of humankind and genetic enhancement. Curriculum and consciousness discussion of American John Dewey (1859–1952), Polish-born Jean Gebser (1905–1975), and Austrian-born Rudolf Steiner (1865–1920) is interwoven, finding commonalities of these philosophers and that of Daniel J. K. Bardy. Language being developed only 50,000 years ago is the defining point for Homo sapiens as the tool of linguistic communication, mutated forward much like the protrusion development …

Teacher Perceptions Of Cross-Cultural Adaptability And Instructional Practices In International Locations, Debra S. Lee

Dissertations and Theses @ UNI

The purpose of the study was to investigate differences in cross-cultural effectiveness between classroom teachers in international settings and classroom teachers in Iowa, and to examine, within a multicultural education framework, instructional practices of international teachers.

It is well documented that in American schools today, classrooms are becoming more diverse in regard to socio-economic status, ethnicity, race, intellectual ability, language, and religious heritage. School children today represent an incredibly diverse population. Conversely, the teacher population continues to be primarily female, White and from a monocultural background. This creates a mismatch between student and teacher backgrounds, perspectives, and cultural understanding, which …

The Chinese Approach To Electronic Transactions Legislation, Zhang Chu, Lingfei Lei

Computer Law Review and Technology Journal

Ecclesiastes reminds us that there is nothing new under the sun, and this may be equally true when it comes to electronic transactions. In the electronic world, agreements are still embodied in contracts, contracts are still entered into when two parties reach an enforceable agreement on terms, and objective evidence still determines whether an agreement has been reached. Fraud and piracy are no less illegal because they happen online. In other words, laws governing the physical world are also relevant in the virtual world. Nevertheless, despite all the similarities, there may still be some differences in form, and there are …

Site-Specific Art Parks On Moral Ground: Distilling Old Whine In New Battles Over The Visual Artists Rights Act, Carrie Jones

Computer Law Review and Technology Journal

Having passed by unanimous vote at the Second Continental Congress, the new Constitution duly declared that "Congress shall have the power [t]o promote the Progress of Science and the useful Arts, by securing for limited Times to Authors rt]he exclusive Right to their respective Writings and Discoveries." Pursuant to that power, Congress enacted the Nation's first copyright law in 1790, intending to promote the artistic progress through a grant of exclusive monopoly for a limited time to the authors of new works. Since then, the United States has successfully urged invention and creation through the full commitment to a comprehensive …

Predictive Congestion Control Mac Protocol For Wireless Sensor Networks, Maciej Jan Zawodniok, Jagannathan Sarangapani

Electrical and Computer Engineering Faculty Research & Creative Works

Available congestion control schemes, for example transport control protocol (TCP), when applied to wireless networks results in a large number of packet drops, unfairness with a significant amount of wasted energy due to retransmissions. To fully utilize the hop by hop feedback information, a suite of novel, decentralized, predictive congestion control schemes are proposed for wireless sensor networks in concert with distributed power control (DPC). Besides providing energy efficient solution, embedded channel estimator in DPC predicts the channel quality. By using the channel quality and node queue utilizations, the onset of network congestion is predicted and congestion control is initiated. …

Genetic algorithms (GAs) are well-known global search techniques anchored on the mechanisms of natural selection and genetics. Because of the time intensive nature of the conventional GA, the micro-GA is proposed as a more time efficient alternative. The feasibility and effectiveness of the …

Spin-System Radio-Frequency Superradiation: A Phenomenological Study And Comparison With Numeric Simulations, Carrie L. Davis, Victor K. Henner, Aleksandr V. Chernatynskiy, Ilia V. Kaganov

Physics Faculty Research & Creative Works

We discuss the coherent behavior of a polarized, nuclear or electron, spin system for which the magnetic dipole radiation emitted in the radio-frequency region, has approximately quadratic dependence on the number of spins. An effective method of describing these phenomena is provided by computer simulation of a microscopic model of the spin system. Important aspects of this numeric simulation are described, together with a comparison with the theoretical predictions. The behavior of the transverse component of the magnetic moment, M⁺ (t), in super-radiant conditions is studied. In addition, the role of dipole-dipole interactions in super-radiation phenomena is investigated in …

The Relationship Between Hypergender Ideology And Rape Empathy Among Male And Female College Students, Erin E. Okun, Suzaime L. Osman

Modern Psychological Studies

The primary purpose of the present study was to examine the relationship between hypergender ideology and rape empathy. A sample of 157 college students completed a questionnaire packet containing demographic variables, the Hypergender Ideology Scale (HOS) and the Rape Empathy Scale (RES). It was predicted that those indicating stronger adherence to extreme stereotypic gender roles would report more empathy for the perpetrator rather than the victim of rape. It was also predicted that men would show stronger adherence to stereotypic gender roles and less victim empathy than women. Results show significant support for all predictions. Discussion involves implications that the …

Unskilled-Unaware And The Role Of Defensive High Self-Esteem, Kim Wilson, Christine Smith

Modern Psychological Studies

The purpose of this study is to examine the relationship between defensive high self-esteem and inability to recognize one's own incompetence. It is hypothesized that individuals displaying defensive high self-esteem will be most likely to show a high correlation between lack of skill and lack of awareness. Participants were assessed for defensive high self-esteem using the Marlowe-Crowne Social Desirability Scale and the Rosenberg Self-Esteem Scale. The unskilled-unaware construct was identified through comparison of prediction versus actual performance on a curriculum-scheduled exam. The null was rejected at p = .01, indicating the likelihood that defensive self-esteem can or does play a …

Farming At Wylie : A Technical Biography 1933- 1963, Bruce Rhind

Theses : Honours

The genesis of this project was my father Graeme Rhind's collection of photographs of farming in Western Australia, dating back to 1929 when his parents first began farming in the wheatbelt near Wyalkatchem. I was interested in the way these photographs illustrated changing farming practices during the following three decades, and how they provided both documentary evidence and stimulated recall of memory. I was also concerned by the loss of knowledge of old photographic collections. The photographs are insufficient by themselves because each image requires specialised knowledge which the viewer may not possess, and that knowledge is lost with the …

A Study Of Feelings Of Alienation Among Relief Teachers Servicing Western Australian Government Metropolitan Primary Schools, Ralph G. Lunay

Theses: Doctorates and Masters

It is perhaps fair to say that the relief (substitute) teacher should be viewed as an extremely important educational resource, Reviewed literature spanning the better part of twenty years indicates that in parts of Australia, the United Kingdom and the United States, many students spend as much as one full year (or more) of their K-12 education having curriculum delivered to them by these individuals. Unfortunately, the literature also indicates that many relief teachers are still viewed by many as less than "real" teachers in terms of perceived competence, skill and capability. In addition to this, the existence of a …

Actor And Partner Effects Among Marital Dyads In Retirement Adjustment And Well-Being, Julie Guenette Howard

Dissertations and Theses

Our understanding of and interest in how retirement impacts the lives of individuals have grown over the past 20 years. Studies to date have ranged from small, convenience samples composed primarily of men to large, national longitudinal samples of men and women from different professional and socioeconomic backgrounds. There is consensus in the literature that older adults generally function better with a partner; however, gaps remain. We know little about the impact of retirement beyond the individual, although research in other areas on couples has produced evidence of crossover and contagion effects relative to depression and other outcomes, including absenteeism, …

Post Reformation Ecclesiology And Missiology--From The Radicals To Wesley: Moving Out Of The Shadow Of Luther And Calvin, Woodrow W. Whidden

Faculty Publications

Whidden’s essay compares the key theological/ecclesiological factors of the Magisterial Reformation tradition with the Radical and Wesleyan ethos and their respective visions of discipleship, theology, ethics, and mission. He then argues that movements which are Arminian in their soteriology; functional, not institutional, in their ecclesiology; and emphasize discipleship (including strict discipline), sanctification, and Gospel ethics are more likely to have a missional bent.
