Comparison Of The Theoretical And Experimental Band Structure Of Poly (Vinylidene Fluoride) Crystal, Chun-Gang Duan, Wai-Ning Mei, John R. Hardy, Stephen Ducharme, Jaewu Choi, Peter A. Dowben

Physics Faculty Publications

The electronic structure and band symmetries of the ferroelectric phase of poly (vinylidene fluoride) (PVDF) are studied by using the first-principles density-functional method. Our calculated results agree well with the angle-resolved photoemission experiments. We find that the PVDF crystal has an energy gap of about 6 eV at the Γ-point. Large dispersion of the valence band is found only along the chain direction, which is consistent with the quasi-one-dimensional nature of PVDF. In particular, the band symmetries of the valence states deduced theoretically are in good agreement with experiment. Finally, further investigations on the electronic structure of poly(trifluoroethylene) (PTrFE) …

Spectral Functions Of The Falicov-Kimball Model With Electronic Ferroelectricity, Wei-Guo Yin, Wai-Ning Mei, Chun-Gang Duan, Hai-Qing Lin, John R. Hardy

Physics Faculty Publications

We calculate the angular resolved photoemission spectrum of the Falicov-Kimball model with electronic ferroelectricity where d- and f-electrons have different hoppings. In mix-valence regimes, the presence of strong scattering processes between d – f excitons and a hole, created by emission of an electron, leads to the formation of pseudospin polarons and novel electronic structures with bandwidth scaling with that of d – f excitons. Especially, in the two-dimensional case, we find that flat regions exist near the bottom of the quasiparticle band in a wide range of the d- and f-level energy difference.

Goal-Converging Behavior Networks And Self-Solving Planning Domains, Bernhard Nebel, Yuliya Lierler

Computer Science Faculty Proceedings & Presentations

Agents operating in the real world have to deal with a constantly changing and only partially predictable environment and are nevertheless expected to choose reasonable actions quickly. One way to address this problem is to use behavior networks as proposed by Maes, which support real-time decision making. Robotic soccer appears to be one domain where behavior networks have been proven to be particularly successful. In this paper, we analyze the reason for the success by identifying conditions that make behavior networks goal converging, i.e., allow them to reach the goals regardless of which particular action selection scheme is used. In …

Cartoons And Pronoun Trouble, Frank Bramlett

English Faculty Publications

In a relatively famous linguistic exchange, Bugs Bunny, Daffy Duck and Elmer Fudd are trying lo determine who is going to be shot. First, the question of whether it's duck season or rabbit season has to be answered. Second, Elmer has to suffer through a barrage of claims and counter-claims in which Bugs and Daffy try to avoid being Elmer's target.

Although I couldn't find a copy of this video, I believe it is Chuck Jones's "Rabbit Seasoning" (1952), and the premise is very similar to 1951's "Rabbit Fire" which I was able to rent on video. At any rate, …

Beyond The Property Tax: Local Government Revenue Diversification, John R. Bartle, Carol Ebdon, Dale Krane

Public Administration Faculty Publications

Local governments in the U.S. rely less on the property tax than they have historically. This long-term trend has been accompanied by important shifts in the composition of local revenues. While the property tax still serves as one primary source of local government revenue, increasingly other sources are used to pay for local government. This paper first examines that trend, the forces behind it, and its regional impact. We then explore trends in three central states- Iowa, Nebraska, and Arkansas -- that have experienced substantial revenue shifts in recent years. A concluding section discusses the options for the future.

Sundials And Their Shady Past, Elliott Ostler, Neal Grandgenett

Teacher Education Faculty Publications

Throughout history, patterned approaches to determining and subdividing time have been considered among the greatest natural mathematical connections ever conceived by mankind. Over the years, this mathematical quest for time has certainly been shrouded in utility (as evidenced by atomic clocks that are accurate to within trillionths of a second by using the mathematically predictable resonance frequencies of elements such as Cesium), but the more romantic and aesthetic virtues of historical time pieces lie in the interplay between pure mathematics and architectural beauty. Although the movement of celestial bodies relative to one another has acted as a basis for the …

Global Diffusion Of The Internet - I: India: Is The Elephant Learning To Dance?, Peter Wolcott, Seymour E. Goodman

Information Systems and Quantitative Analysis Faculty Publications

With his proclamation in 1998 that "IT is India's tomorrow", Prime Minister Vajpayee captured a vision of a 21st century India substantially different from that of the previous century, with its high levels of poverty, bloated bureaucracies, and protectionist policies. He envisioned the new India as a major IT power, fully integrated with the global economy, bringing about substantial domestic and international benefit. The Internet is a key to this vision, both as an enabler of technology-based change, and as an indicator of the vision's fulfillment.

Using an analytic framework developed by the authors and others, this study documents the …

Trace Analysis Of Organic Substances, Alan Giltinan

Theses

One of the major challenges facing the pharmaceutical industry is the control of the amount of trace contaminants during the manufacture of organic substances. Lowering the level of contamination improves the quality of the product and reduces possible side effects.

One of the main techniques used to detect trace contaminants is UV-VIS spectroscopy, where the unique absorption fingerprint of a chemical reveals its presence. UV-VIS absorption is based upon the Beer-Lambert Law. The critical point to note about this law is that the absorption is exponentially dependent on both the concentration of the absorber and the pathlength traversed by the …

Jack Of All Trades Or Master Of One? Specialization, Trade And Money, Gabriele Camera, Robert R. Reed, Christopher Waller

Economics Faculty Articles and Research

We consider a model of decentralized exchange where individuals choose the set of goods they produce. Specialization involves producing a smaller set of goods and doing it more proÞciently. In doing so, agents reduce production costs, but also reduce the ease of trading their output. We derive the equilibrium degree of specialization and examine how it is affected by underlying fundamentals. Due to the existence of a hold-up problem, individuals specialize too little relative to the social optimum. Introducing money leads to more specialization relative to barter and increases welfare.

Hatch-Waxman Reform And Accelerated Market Entry Of Generic Drugs: Is Faster Necessarily Better?, Sarah Kammer

Faculty Publications

Recently there has been a considerable amount of pressure to accelerate consumer access to generic drugs, which are significantly less expensive than their brand-name counterparts. One way to bring generic drugs on to the market sooner is through revision of the existing law relating to pharmaceutical patents. This iBrief describes recent regulatory changes to the Drug Price Competition and Patent Term Restoration Act (the Hatch-Waxman Act), which governs the patenting process for new drug products, as well as current legislative efforts to speed generic access through Hatch-Waxman reform. This iBrief also assesses whether these changes will be beneficial to consumers …

Engineering For Expression Of The Cold Regulated Barley Protein Hvcr21 In E. Coli, Kathleen Graupman

The Journal of Undergraduate Research

HVCR21 is a barley protein known to be cold regulated at the mRNA level. However, its function as well as the affect of low temperature on its translation are unknown. The purpose of this project was to engineer E. coli to express recombinant HVCR21. PGR primers were designed for the 5' and 3' ends of the HVCR21 coding region. The primers were also designed with a 5' SacI restriction site and a 3' Pst I restriction site. After ligation of the PCR product into the pCR4-TOPO vector, bacteria were transformed and plated and the successful transformant verified by PCR. The …

Influence Of Normal Daytime Fat Deposition On Laboratory Measurements Of Torpor Use In Territorial Versus Nonterritorial Hummingbirds, Donald R. Powers, A R. Brown, J A. Van Hook

Faculty Publications - Department of Biological & Molecular Science

Fat deposition and torpor use in hummingbirds exhibiting distinct foraging styles should vary. We predicted that dominant territorial hummingbirds will use torpor less than subordinate nonterritorial species because unrestricted access to energy by territory owners allows for fat storage. Entry into torpor was monitored using open-flow respirometry on hummingbirds allowed to accumulate fat normally during the day. Fat accumulation was measured by solvent fat extraction. Territorial blue-throated hummingbirds (Lampornis clemenciae) had the highest fat accumulation and used torpor only 17% of the time. Fat storage by L. clemenciae averaged 26% of lean dry mass (LDM) in 1995 and 18% in …

Study Of Ionic Conductivity Profiles Of The Air Cathode Of A Pemfc By Ac Impedance Spectroscopy, Qingzhi Guo, Maria Cayetana, Yu-Min Tsou, Emory S. De Castro, Ralph E. White

Faculty Publications

A characterization of the ionic conduction of the active layer of a polymer electrolyte membrane fuel cell (PEMFC) cathode by ac impedance measurement at open-circuit potential conditions was conducted. Porous electrode theory was used to derive a compact equation, ∂2Φ̑2/∂y2+∂lnf(y)/∂y×∂Φ̑2/∂y−R/f(y)(1+jΩ)Φ̑2=0, to solve for the impedance response of a cathode at open-circuit potential conditions. This equation includes a parameter R, the ratio of an ionic resistance (evaluated at the active layer/membrane interface), to the total charge-transfer resistance of the active layer. The influence of an assumed ionic conductivity distribution profile f(y) on the error in the estimation of total double-layer …

Full Cell Mathematical Model Of A Mcfc, N. Subramanian, B. S. Haran, Ralph E. White, Branko N. Popov

Faculty Publications

A theoretical model for the molten carbonate fuel cell was developed based on the three-phase homogeneous approach. Using this model, the contribution of different cell components to losses in cell performance has been studied. In general, at low current densities, the electrolyte matrix contributed to the major fraction of potential losses. Mass transfer effects became important at high current densities and were more prominent at the cathode. Electrolyte conductivity and cathode exchange current density seemed to play a limiting role in determining cell performance. Using the model, the maximum power density from a single cell for different cell thicknesses was …
