Apollonius Of Perga: Historical Background And Conic Sections, Ashley Allen

Senior Honors Theses

Apollonius of Perga greatly contributed to geometry, specifically in the area of conics. Through the study of the “Golden Age” of Greek mathematics from about 300 to 200 B.C., Apollonius, who lived from about 262 to 190 B.C., is seen as an innovative geometer whose theories were eventually proved factual. By investigating his theorems on how the different kinds of conic sections are formed, the standard equations for each conic will be better understood. The achievements that have been made as a result of conics include flashlights to whispering galleries.

The Impact Of The No Child Left Behind Act On The K-8 Setting, Kara Robertson

Senior Honors Theses

The No Child Left Behind Act (NCLB), which was implemented in 2002, is changing the classroom for teachers and students. The legislation is widely discussed across the nation and people are deciding whether or not this change is suitable for education. The No Child Left Behind Act is affecting the core subjects in the classroom. After evaluating literature on the subject, it is obvious that there are two clear sides to this legislation. There are also actions that can be taken by teachers within the classroom to best utilize NCLB. As a future educator, it is important to evaluate NCLB …

Sparticus: Small Particles In Cirrus Science And Operations Plan, J. Mace, E. Jensen, G. Mcfarquhar, J. Comstock, T. Ackerman, David L. Mitchell, X. Liu, T. Garrett

Publications (E)

From a mass-weighted perspective, cirrus clouds exert an enormous influence on the radiative energy budget of the earth?s climate system. Owing to their location in the cold upper troposphere, cirrus can significantly reduce the outgoing longwave radiation while, at the same time, remaining relatively transmissive to solar energy. Thus, cirrus clouds are the only cloud genre that can exert a direct radiative warming influence on the climate system (Ackerman et al. 1988). It is not surprising, therefore, that general circulation models (GCMs) are especially sensitive to the presence of cirrus in the model atmosphere. Lohmann and Roeckner (1995), for instance, …

State Of The States 2009: Renewable Energy Development And The Role Of Policy, Elizabeth Doris, Joyce Mclaren, Victoria Healey, Stephen Hockett

Publications (E)

As U.S. states increasingly focus on developing renewable energy resources, there is a need to track the progress of development, as well as the policies and support mechanisms being implemented to encourage this development. Beyond tracking, the evaluation of policy measures is necessary to determine their effectiveness, guide future efforts, and efficiently allocate resources. This report addresses each of these needs. It provides a detailed picture of the status of renewable energy development in each of the U.S. states using a variety of metrics and discusses the policies being used to encourage this development. The report then explores the context …

Nonlinearity In Large Amplitude Oscillatory Shear (Laos) Of Different Viscoelastic Materials, Xin Li, Shi-Qing Wang, Xiaorong Wang

College of Polymer Science and Polymer Engineering

The present work investigates nonlinear behavior in large amplitude oscillatory shear (LAOS) of four different polymeric materials using simultaneous conventional rheometric measurements and particle-tracking velocimetric observations. In contrast to most studies in the literature that treat nonlinearity in LAOS in steady state, we emphasize by the present four examples that nonlinearity in LAOS often arise in complex fluids due to time-dependent rearrangement of their microstructures in response to LAOS. Consequently, no correlation is obvious between strain dependence of the steady-state stress response and the time-dependent characteristics of the steady-state response. For instance, a highly viscoelastic material made of nano-sized polybutadiene …

Protecting Quantum Information With Entanglement And Noisy Optical Modes, Mark M. Wilde, Todd A. Brun

Faculty Publications

We incorporate active and passive quantum error-correcting techniques to protect a set of optical information modes of a continuous-variable quantum information system. Our method uses ancilla modes, entangled modes, and gauge modes (modes in a mixed state) to help correct errors on a set of information modes. A linear-optical encoding circuit consisting of offline squeezers, passive optical devices, feedforward control, conditional modulation, and homodyne measurements performs the encoding. The result is that we extend the entanglement-assisted operator stabilizer formalism for discrete variables to continuous-variable quantum information processing. © 2009 Springer Science+Business Media, LLC.

Bounds On Smooth Matrix Coefficients On L2-Spaces, Hongyu He

Faculty Publications

Let G be a semisimple Lie group with a finite number of connected components and a finite center. Let K be a maximal compact subgroup. Let X be a smooth G-space equipped with a G-invariant measure. In this paper, we give upper bounds for K-finite and -smooth matrix coefficients of the regular representation L2(X) under an assumption about supp. Furthermore, we show that this bound holds for unitary representations that are weakly contained in L2(X). Our result generalizes a result of Cowling-Haagerup-Howe (J Reine Angew Math 387:97-110, 1988). As an example, we discuss the matrix coefficients of the O(p, q) …

Geometry Of L₁(Μ) For Vector-Valued Measure, Part Ii, Iwo Labuda

Analysis Seminar

Let μ be a measure from a σ-algebra of subsets of a set �� into a sequentially complete Hausdorff topological vector space ��. Assume that the convex hull of the range of μ is bounded in �� and denote by L₁(μ) the space of scalar-valued functions on �� that are integrable with respect to the vector measure μ. Sometimes a property of �� is inherited by L₁(μ). I will show that the bounded multiplier property passes from �� to L₁(μ). Answering a 1972 question of Erik Thomas, I will show that for a large class of F-spaces ��, the non-containment …

Private Warehouse Investment Strategies In Small Versus Large Manufacturing Firms, John E. Spillan, Michael A. Mcginnis, Jonathan W. Kohn

Journal of Transportation Management

The research reported in this manuscript empirically compares the private warehouse investment strategies of small and large manufacturing firms. Mail surveys were administered to independent samples of small and large United States manufacturing firms. This research is based on a series of identically worded questions administered to both samples. Data was factor analyzed and cluster analyzed to identify three private warehouse investment strategies for small and large firms and two strategies for large firms. Analyses of three independent variables further evaluated differences in private warehouse investment strategies. Finally, the warehouse mix of small and of large firms was compared. This …

Astronomy: Faculty Publications

We present results from a multiwavelength study of 29 sources (false detection probabilities cent) from a survey of the Great Observatories Origins Deep Survey-North (GOODS-N) field at 1.1 mm using the Astronomical Thermal Emission Camera (AzTEC). Comparing with existing 850 μm Submillimetre Common-User Bolometer Array (SCUBA) studies in the field, we examine differences in the source populations selected at the two wavelengths. The AzTEC observations uniformly cover the entire survey field to a 1σ depth of ∼1 mJy. Searching deep 1.4 GHz Very Large Array (VLA) and Spitzer 3-24 μm catalogues, we identify robust counterparts for 21 1.1 mm sources, …

Rationality And Humanity: A View From Feminist Economics, Julie A. Nelson

Economics Faculty Publication Series

DOES RATIONAL CHOICE THEORY (RCT) HAVE SOMETHING IMPORTANT to contribute to the humanities? Usually the arguments for answering “yes” to this question go something like the following: The application of RCT has proved to be a powerful tool in economics and the social sciences, leading to clear and rigorous insights unattainable from less precise methods. Therefore, by also harnessing this power, the disciplines in the humanities could advance toward becoming more elegant, rational, and forceful in their explorations of human behavior. As an economist, I’d like to address this argument on its home ground. Has the use of RCT advanced …

Carbon Capture And Storage: Combining Economic Analysis With Expert Elicitations To Inform Climate Policy, Erin D. Baker, Haewon Chon, Jeffrey M. Keisler

Management Science and Information Systems Faculty Publication Series

The relationship between R&D investments and technical change is inherently uncertain. In this paper we combine economics and decision analysis to incorporate the uncertainty of technical change into climate change policy analysis. We present the results of an expert elicitation on the prospects for technical change in carbon capture and storage. We find a significant amount of disagreement between experts, even over the most mature technology; and this disagreement is most pronounced in regards to cost estimates. We then use the results of the expert elicitations as inputs to the MiniCAM integrated assessment model, to derive probabilistic information about the …

Second Life Complements The Internet For Reference Librarians, Florence Tang

Georgia Library Quarterly

The article describes the Second Life culture as an interactive virtual environment from the perspective of a reference librarian. The cited advantages of using Second Life are synchronous interaction with other people, clearer appearance of chat text messages, incorporation of social norms, and accessibility. Among the noted obstacles to using Second Life are its price, intentional distress of other avatars, empty virtual public places, less hierarchy among participants, chatting via rapid typing, and quick change of landscapes and avatars.

Long-Wavelength Structural Anomalies In Jammed Systems, Leo Silbert, Moises Silbert

Publications

The structural properties of static, jammed packings of monodisperse spheres in the vicinity of the jamming transition are investigated using large-scale computer simulations. At small wave number k, we argue that the anomalous behavior in the static structure factor, S(k)similar to k, is consequential of an excess of low-frequency, collective excitations seen in the vibrational spectrum. This anomalous feature becomes more pronounced closest to the jamming transition, such that S(0)-> 0 at the transition point. We introduce an appropriate dispersion relation that accounts for these phenomena that leads us to relate these structural features to characteristic length scales associated with …

Networking The Parties: A Comparative Study Of Democratic And Republican Convention Delegates In 2008, Seth E. Masket, Michael T. Heaney, Joanne M. Miller, Dara Z. Strolovich

Working Papers

Parties‐as‐networks is an emerging approach to understanding American political parties as decentralized, nonhierarchical, fluid systems with porous boundaries of a wide array of actors. Parties‐asnetworks include interest groups, social movements, political consultants, and advocacy organizations, in additional to the usual suspects of elected officials, party officials, and citizen‐activists. This approach ameliorates several deficits of the traditional, tripartite view of parties in government, in elections, and as organizations. The authors apply the parties‐as‐networks approach using data from surveys of delegates at the 2008 Democratic and Republican national conventions. Analysis of delegates’ memberships in a wide variety of organizations demonstrates that Democrats …

The Response To Nuclear Proliferation, Annelies Z. Kamran

Working Papers

This paper uses the methods of social network analysis to discover the structural patterns of cooperation that arose in response to a global traditional security problem. It does this by mapping compulsory and institutional power relations (Barnett and Duvall 2005) among actors responding to the proliferation of nuclear weapons since the end of the Cold War. For the institutional power measure, I use treaty and international agreement membership; and for the compulsory power measure, I use contractual obligations for nuclear expertise, materials, and technology. By mapping the relationships at the system level of world politics, including individual states as well …

Effects Of Tide Gate Replacement On Water Temperature In A Freshwater Slough In The Columbia River Estuary, Sara Ennis

Environmental Science and Management Professional Master's Project Reports

Dramatic declines in salmon populations in the Pacific Northwest have brought new attention to the importance of estuarine rearing habitats. Levees and tide gates used to convert estuarine wetlands into farmland have reduced available habitat by more than half of historical levels. Recent efforts to restore estuarine habitats include tide gate replacement, though this method has been poorly studied. As a key indicator of salmon habitat suitability, temperature was used to evaluate the effects of tide gate replacement in a tidally influenced freshwater slough in the Lower Columbia River estuary. Three tide gates in the largest slough on Tenasillahe Island …

Crop Yield Gaps: Their Importance, Magnitudes, And Causes, David B. Lobell, Kenneth G. Cassman, Christopher B. Field

Nebraska Center for Energy Sciences Research: Publications

Future trajectories of food prices, food security, and cropland expansion are closely linked to future average crop yields in the major agricultural regions of the world. Because the maximum possible yields achieved in farmers’ fields might level off or even decline in many regions over the next few decades, reducing the gap between average and potential yields is critical. In most major irrigated wheat, rice, and maize systems, yields appear to be at or near 80% of yield potential, with no evidence for yields having exceeded this threshold to date. A fundamental constraint in these systems appears to be uncertainty …

Isomeric Effects With Di-Iodobenzene (C6H4I2) On Adsorption On Graphite, Keisuke Fukutani, Ning Wu, Peter A. Dowben

Peter Dowben Publications

Differences are seen in the adsorption of 1,2-di-iodobenzene, 1,3-di-iodobenzene, and 1,4-di-iodobenzene on graphite, as a function of exposure, using core level photoemission. The isomer 1,3-di-iodobenzene exhibits significant differences from 1,2-di-iodobenzene, and 1,4-di-iodobenzene in apparent sticking coefficients and core level binding energies. 1,3-Di-iodobenzene adsorb on graphite at 110 K in a strongly Stranski–Krastanov or Volmer–Weber (island) growth mode. The implication is that, even for small molecules adsorption, the adsorbate dipole in the plane of surface and the choice of isomer may matter.
