Electrochemical Generation Of Superoxide In Room-Temperature Ionic Liquids, Inas M. Alnashef, Matthew L. Leonard, Matthew C. Kittle, Michael A. Matthews, John W. Weidner

Faculty Publications

We have demonstrated that superoxide ion can be generated electrochemically in room-temperature ionic-liquid solvents. In the absence of impurities, cyclic voltammetry showed that the super oxide ion is stable in these solvents. Similar superoxide ion chemistry has previously been demonstrated in volatile and environmentally suspect aprotic solvents such as dimethyl formamide and acetonitrile. However, ionic liquids are nonvolatile and should minimize the problems of secondary solvent waste. It is proposed that the resultant superoxide ion can be used to perform low temperature oxidation of wastes. Low-temperature oxidation of waste solvents can provide a much needed alternative to high-temperature waste incinerators, …

Cellular Senescence: Ex Vivo P53-Dependent Asymmetric Cell Kinetics., Lakshmi Rambhatla, Shirley A. Bohn, Patrizia B. Stadler, Jonathan T. Boyd, Ronald A. Coss, James L. Sherley

Department of Radiation Oncology Faculty Papers

Although senescence is a defining property of euploid mammalian cells, its physiologic basis remains obscure. Previously, cell kinetics properties of normal tissue cells have not been considered in models for senescence. We now provide evidence that senescence is in fact the natural consequence of normal in vivo somatic stem cell kinetics extended in culture. This concept of senescence is based on our discovery that cells engineered to conditionally express the well-recognized tumor suppressor protein and senescence factor, p53, exhibit asymmetric cell kinetics. In vivo, asymmetric cell kinetics are essential for maintenance of somatic stem cells; ex vivo, the same cell …

Pedestrian Reaction To Crossing Signal Delay, Deogratias Eustace

Civil and Environmental Engineering and Engineering Mechanics Faculty Publications

Pedestrians with experience at a certain intersection learn the length of signal cycle, the phase change pattern of the signal, and the order in which traffic flow is released. These pedestrians have a higher chance of noncompliance with traffic signals. Most of the noncomplying pedestrians save a small amount of time, less than 18 seconds, by crossing the road shortly before the onset of the WALK signal indication. The study agrees with other studies done in the past that pedestrians ignore the traffic signals. They do so in order to reduce their own time delays.

Water Distribution Modeling, Thomas M. Walski, Donald V. Chase, Dragan A. Savic

Written by industry experts, it provides a practical resource for engineers and modelers that goes well beyond being a how-to guide for typing data into a computer program. It contains straightforward answers to common questions related both to modeling and to distribution systems in general.

This textbook walks the practicing engineer or student through the modeling process from start to finish — …

A Framework For The Implementation Of An Iso 9000 Based Certification Program For Printed Circuit Board Manufacturers, Adam Y. Maamoun

Retrospective Theses and Dissertations

ISO 9000:2000 is the newest version of the ISO 9000 family of standards. Unlike the 1994 version, it does not distinguish between servicing, testing and designing standards. It emphasizes quality improvement rather than quality control and briefly explains how to implement the Plan-Do-Check- Act (PDCA) cycle for improvement and the use of statistical techniques to improve the quality of process and product instead of controlling the quality of the output. The thesis explains why companies need to be certified and how to implement quality improvement programs.

The objective of this thesis is to provide generic certification guidelines for printed circuit …

A Unified Approach To Dynamic Modeling Of High Switching Frequency Pwm Converters, Christopher J. Iannello

Retrospective Theses and Dissertations

This dissertation will present the development of a unified approach for dynamic modeling of the PWM and soft-switching power converters. Dynamic modeling of non-linear power converters is very important for the design and stability of their closed loop control. While the use of equivalent circuits is often preferred due to simulation efficiency issues, no unified and widely applicable method for the formulation of these equivalents exists.

A review of conventional modeling technique via the method of state-space averaging will be carried out. Complete development of the averaged, equivalent circuit models for the nonlinear power switch/diode combination in modem power converters …

Scintillation Behind The Collecting Lens Of A Receiver, Clarissa A. Fleming Russell

Retrospective Theses and Dissertations

One of the negative effects that a laser beam experiences as it propagates through the atmosphere is intensity fluctuations or scintillation. Because scintillation-- as it pertains to laser radar and laser satellite communication systems-- is the main subject of this research, the assumption of an optical element ( such as a Gaussian lens) along the propagation path in front of the detector is valid. The mathematical addition of optical elements to the propagation path is treated using the ABCD ray matrix method. The expression for scintillation is derived, analyzed, and numerically calculated for positions to the left and right of …

Surface Fracturing Of Armatures Within Helical Flux-Compression Generators, Paul Nicholas Worsey, Jason Baird

Mining Engineering Faculty Research & Creative Works

Tubes of aluminum and of copper filled with C-4 high-explosive were tested during this study of high strain rate effects within thin metallic structures performed as an adjunct to helical flux-compression generator research at the University of Missouri-Rolla. Focusing on the stresses within a relatively thin metallic structure when brisant explosives abutting the structure are detonated, this study directly affects the understanding of flux cutoff and high strain-rate resistivity changes in an expanding armature. The detonation wave is compressive, and the shock waves resulting from its transmission into a thin metallic structure cause both compressive and tensile regions, posing an …

Method Of Creating Ultra-Fine Particles Of Materials Using A High-Pressure Mill, Marian Mazurkiewicz

Mining Engineering Faculty Research & Creative Works

A method for creating ultra-fine particles of material using a high-pressure mill is described. The method includes placing a material in a first chamber and subjecting the material to a high-pressure liquid jet to divide it into particles. These particles are then transferred to a second chamber in which they are subjected to cavitation to further divide the particles into relatively smaller particles. These relatively smaller particles are then transferred to a third chamber, in which the particles collide with a collider to still further divide them into ultra-fine particles of the material. The mill of the present invention includes …

Exploring The Potential Usefulness Of Binary Space Partitions In Architectural Representations, Michael Hoon

Theses

There have been recent advances developed within the computer gaming industry that have made real-time first-person perspective spatial experiences feasible on the personal computer. Principally through the use of binary space partition tree structures, developers of threedimensional gaming environments are able to convey to computer users a convincing sense of movement through space. The technology behind these advances may be termed as a particularization of Virtual Reality. This paper will outline research intended to determine the possible usefulness of binary space partitions in the fields of architectural education and practice. The feasibility of this technology was studied by directly observing …

Small Business Owners' Measures Of Success, Elizabeth A. Walker

Theses: Doctorates and Masters

Small business plays a significant part in the economy of all nations because of its revenue contribution and as a generator of employment. In the Australian context, small businesses account for 85% of all businesses, employ 40% of the total workforce and contribute $75 billion annually to Industry Gross Product. All of these numerical indicators highlight the financial importance of small business, which is also how small business success has traditionally been measured. These traditional success measures have been by increases in financial performance criteria, such as return on investment, turnover or profit, or by increases in number of staff.

The Reproductive Biology And Temporal Distribution Of A Great Egret And Nankeen Night Heron Colony At The Perth Zoo, Robyn Phillimore

Theses: Doctorates and Masters

A colony of Great Egrets (Ardea alba) and Nankeen Night Herons (Nycticorax caledonicus) has existed at the Perth Zoo in Metropolitan Perth for over 25 years. The colony is particularly significant for the conservation and management of Great Egrets in Western Australia as it is the only colony located in the Metropolitan area. Baseline information of their breeding biology was needed to facilitate the development of management guidelines for the zoo colony. Foraging behaviour was used to highlight specific adaptations in hunting strategies and diet. However, it was not possible to observe foraging Nankeen Night Herons as they forage at …

Downsizing : An Analysis Of Organisational Strategies And Human Resource Management Outcomes, Cecil A. Clabaugh

Theses: Doctorates and Masters

The objective of this research was to examine the relationship between loss and retention of key employees in downsizing organisations and organisational performance. The purpose of this was to develop an understanding of the organisational performance that results when downsizing organisations are unable to retain their key workers. The secondary objective of the research was to examine the factors that make up a downsizing organisation's employee selection process in order to determine how these factors affect loss and retention of key workers. The research was guided by a theoretical framework developed by Kozlowski et al (1993) and Thornhill and Saunders …

Financial Intermediation And Economic Performance In Zimbabwe, Gift Chirozva

Theses: Doctorates and Masters

Financial literature is replete with theoretical and empirical evidence suggesting financial development has a causal effect on economic growth. Yet there is no consensus on the finance-growth nexus. The direction of causality is still controversial In fact, classical economists argue that financial factors are neutral and hence cannot have real effects. Critics argue the traditional methods of identifying long run economic relationships fail to address the methodological conflict between equilibrium implied by theory and the disequilibria in the data. The rise of new representation techniques such as the General Methods of Moments (GMM) and vector autoregression [VAR] brought with them …

Vlsi Implementation Of A Massively Parallel Wavelet Based Zerotree Coder For The Intelligent Pixel Array, Geoffrey N. Alagoda

Mobile video communications in particular encompasses a number of technical hurdles that generally steer technological advancements towards devices that are low in complexity, low in power usage yet perform the given task efficiently. Devices of this nature have been made available through the use of massively parallel processing arrays such as the Intelligent Pixel Processing Array. The Intelligent Pixel Processing array is a novel concept that integrates a parallel image capture …

Design And Implementation Of A Biologically Realistic Olfactory Cortex In Analog Vlsi, Jose C. Principe, Vitor G. Tavares, John G. Harris, Walter J. Freeman

Electrical and Computer Engineering Faculty Research & Creative Works

This paper reviews the problem of translating signals into symbols preserving maximally the information contained in the signal time structure. In this context, we motivate the use of nonconvergent dynamics for the signal to symbol translator. We then describe a biologically realistic model of the olfactory system proposed by Walter Freeman that has locally stable dynamics but is globally chaotic. We show how we can discretize Freemans model using digital signal processing techniques, providing an alternative to the more conventional Runge-Kutta integration. This analysis leads to a direct mixed signal {analog amplitude/discrete time) implementation of the dynamical building block that …

Robust Adaptive Critic Based Neurocontrollers For Missiles With Model Uncertainties, Zhongwu Huang, S. N. Balakrishnan

Mechanical and Aerospace Engineering Faculty Research & Creative Works

A Lyapunov theory-based controller is proposed in this paper for robustness against model uncertainties in the control of a missile. The controller design consists of two parts; in the first phase, an optimal nonlinear controller is designed with neural networks for tracking. This is based on the adaptive critic method that consists of one neural network called the supervisor or critic and a second network called an action network or a controller. Each network is trained through the output of the other network and equations related to optimal control. When their outputs are mutually consistent, the controller network output is …

The Technologies Of Property Rights: Choice Among Alternative Solutions To Tragedies Of The Commons, Bruce Yandle, Andrew P. Morriss

Faculty Scholarship

Garrett Hardin's classic description of the tragedy of the commons tells us that all environmental problems require a property rights solution. The property solution or rule may call for the definition and enforcement of common, public, or private property rights, but any escape from the tragedy requires some rationing mechanism that allocates a form of property rights to some entity. These solutions fall into one of two broad traditions within economics: the Pigouvian, or regulatory tradition, and the Coasean, or market-based tradition. Any proposal for action in either tradition implies some definition of property rights. The difference lies in the …

Rate-Matching Packet Scheduler For Real-Rate Applications, Kang Li, Jonathan Walpole, Dylan Mcnamee, Calton Pu, David Steere

Computer Science Faculty Publications and Presentations

A packet scheduler is an operating system component that controls the allocation of network interface bandwidth to outgoing network flows. By deciding which packet to send next, packet schedulers not only determine how bandwidth is shared among flows, but also play a key role in determining the rate and timing behavior of individual flows. The recent explosion of rate and timing-sensitive flows, particularly in the context of multimedia applications, has focused new interest on packet schedulers. Next generation packet schedulers must not only ensure separation among flows and meet real-time performance constraints, they must also support dynamic fine-grain reallocation of …

Cleaning Up The Tracks: Superfund Meets Rails-To-Trails, Clifford J. Villa

Faculty Scholarship

For more than one hundred years, railroad cars rumbled and roared along tracks in the Coeur d'Alene River Basin, serving the mining industry in the Panhandle of northern Idaho. As in many parts of the American West, the history of railroads in northern Idaho largely reflects the history of mining in the region. The first gold was discovered in this area in 1883, the same year that the area saw its first line of the Northern Pacific Railroad. In 1885, the Bunker Hill mine was established near the present town of Kellogg. Four years later, the first rail line of …

From Ambivalence To Activism: Australia And The Negotiation Of The 1968 Nuclear Non-Proliferation Treaty, Christopher Hubbard

Theses: Doctorates and Masters

This Dissertation presents a study of Australia's involvement in the negotiation and early interpretation of the 1968 Nuclear Non-Proliferation Treaty (NPT), an instrument which remains the most important global nuclear arms control measure in international law. Using data from recently released Australian government documents, the study analyses the process by which Australia was transformed from an ambivalent nuclear sceptic within the Western alliance, into a steadfast global campaigner against the spread of nuclear weapons. It concludes that Australia's urgent search during 1967 and 1968 for coherence in its policy on nuclear weapons acquisition, largely played out within sections of the …

The New Social Discipline : A Critical Analysis Of Federal Drug-Free Workplace Legislation And Employee Drug Testing, Matthew T. Lammers

Dissertations and Theses @ UNI

In this research I contend that the arguments for drug-free workplaces are framed within a narrative of science that lends authenticity to the recurring themes that drug testing promotes the health, safety, and productivity of the American workforce. The sense of authenticity effectively delimits the discourse of drug testing and presents the complexities of drug abuse in binary oppositions that contribute to normalizing the behavior of all individuals, not just those who abuse drugs. I suggest that the process of normalization reproduces the delimitation of discourse and provides justifications for introducing drug testing into areas of society beyond the walls …
