A Foveated System For Wilderness Search And Rescue In Manned Aircraft, Carson D. Fenimore

Theses and Dissertations

Wilderness search and rescue can be assisted by video searchers in manned aircraft. The video searcher's primary task is to find clues on the ground. Due to altitude, it may be difficult to resolve details on the ground with a standard video camera. As the video streams at a constant frame rate, the searcher may become distracted by other tasks. While handling these tasks the searcher may miss important clues or spend extra time flying over the search area; either outcome decreases both the effectiveness of the video searcher and the chances of successfully finding missing persons. We develop an …

What Good Is Growth? Reconsidering Dewey On The Ends Of Education, R.W. Hildreth

Education and Culture

One of the most persistent criticisms of John Dewey is his failure to provide definite ends for education. This essay reconstructs Dewey’s educational thought to provide more guidance on the nature of educational ends. Rather than impose external ends and a rigid curriculum, Dewey provides evaluative criteria so that citizens themselves can assess the educational and democratic value of any practice, curricula or institution. The political implications of this position are profound. It pushes away from expert driven models of educational authority and towards empirically grounded deliberative processes to guide educational practice and policy.

Political Goals And Social Ideals: Dewey, Democracy, And The Emergence Of The Turkish Republic, Charles Dorn, Doris A. Santoro

Education and Culture

Most historical scholarship on John Dewey’s 1924 educational mission to Turkey has focused on the degree to which the educator and philosopher’s recommendations were actually implemented. By bringing the disciplinary lenses of history and philosophy to bear on Dewey’s mission, this collaborative study differs from previous work by illuminating the disjuncture between Dewey’s conception of democratic localism as essential to an educational system in a vibrant democracy (a social ideal) and Turkish officials’ view of centralized, formal education as a means to promulgate a homogeneous, modern, secular and democratic identity for their new nation-state (a political goal).

A Network Conditions Estimator For Voice Over Ip Objective Quality Assessment, Carlos Daniel Nocito

Open Access Theses

Objective quality evaluation is a key element for the success of the emerging Voice over IP (VoIP) technologies. Although there are extensive economic incentives for the convergence of voice, data, and video networks, packet networks such as the Internet have inherent incompatibilities with the transport of real time services. Under this paradigm, network planners and administrators are interested in ongoing mechanisms to measure and ensure the quality of these real time services. Objective quality assessment algorithms can be broadly divided into a) intrusive (methods that require a reference signal), and b) non intrusive (methods that do not require a known …

Surface Modeling Topsoil Distribution On A Reclaimed Coal-Mine Site At Blackmesa Mine Complex, Kayenta, Arizona, Janine Ferarese

Geography and the Environment: Graduate Student Capstones

A necessary precursor to ensure proper vegetation growth on reclaimed coal-mine areas is even distribution of topsoil. This capstone discusses development of surface models to describe the accurate determination and visualization of the distribution of topsoil. Prediction surfaces from topsoil-depth point samples were created using the surface interpolation methods, Inverse Distance Weighted and Kriging. The validity and accuracy of each method was assessed to determine the best method to evaluate actual topsoil distribution at a coal mining site. The model can be utilized by non- spatially trained personnel working in the mining arena as an aid in assessing how appropriately …

De Sitter Gravity From Lattice Gauge Theory, Simon Catterall, Daniel Ferrante, Arwen Nicholson

Physics - All Scholarship

We investigate a lattice model for Euclidean quantum gravity based on discretization of the Palatini formulation of General Relativity. Using Monte Carlo simulation we show that while a naive approach fails to lead to a vacuum state consistent with the emergence of classical spacetime, this problem may be evaded if the lattice action is supplemented by an appropriate counter term. In this new model we find regions of the parameter space which admit a ground state which can be interpreted as (Euclidean) de Sitter space.

A Theoretical Study On The Rank’S Dependence With Electric Size Of The Inverse Finite Element Matrix For Large-­‐Scale Electrodynamic Analysis, Haixin Liu, Dan Jiao

Department of Electrical and Computer Engineering Technical Reports

The rank of the inverse finite-element matrix is theoretically studied for 1-D, 2-D, and 3-D electrodynamic problems. We find that the rank of the inverse finite-element matrix is a constant irrespective of electric size for 1-D electrodynamic problems. For 2-D electrodynamic problems, the rank grows very slowly with electric size as square root of the logarithm of the electric size of the problem. For 3-D electrodynamic problems, the rank scales linearly with the electric size. The findings of this work are both theoretically proved and numerically verified. They are applicable to problems with inhomogeneous materials and arbitrarily shaped structures.

A Theoretical Study On The Rank Of The Integral Operators For Large-­‐Scale Electrodynamic Analysis, Wenwen Chai, Dan Jiao

Department of Electrical and Computer Engineering Technical Reports

We theoretically prove that the minimal rank of the interaction between two separated geometry blocks in an integral-equation based analysis of general three-dimensional objects, for a prescribed error bound, scales linearly with the electric size of the block diameter. We thus prove the existence of the error-bounded low-rank representation of both surface and volume based integral operators for electrodynamic analysis, irrespective of electric size and scatterer shape. The theoretical analysis developed in this work permits an analytical study of the minimal rank for a prescribed accuracy, for arbitrarily shaped objects with arbitrary electric sizes. Numerical experiments have verified its validity. …

Does Gender Bias Influence Awards Given By Societies?, Mary Anne Holmes, Pranoti Asher, John Farrington, Rana Fine, Margaret S. Leinen, Phoebe Leboy

Department of Earth and Atmospheric Sciences: Faculty Publications

AGU is a participant in a U.S. National Science Foundation (NSF)–funded project called Advancing Ways of Awarding Recognition in Disciplinary Societies (AWARDS), which seeks to examine whether gender bias affects selection of recipients of society awards. AGU is interested in learning why there is a higher proportion of female recipients of service and education awards over the past 2 decades. Combined with a lower rate of receipt of research awards, these results suggest that implicit (subconscious) bias in favor of male candidates still influences awardee selection.

Information Literacy For Multiple Disciplines: Toward A Campus-Wide Integration Model At Indiana University, Bloomington, Brian Winterman, Carrie Donovan, Rachel Slough

Communications in Information Literacy

Within disciplines are a set of shared values and thought processes that students must master in order to become participants of that discipline. Information literacy as defined by the ACRL is a set of standards and principles that can apply to all disciplines. In order to produce information literate undergraduates in a given discipline, information literacy standards must be integrated with the values and processes of the discipline. In this study, librarians partnered with faculty in gender studies and molecular biology to integrate information literacy with courses in those areas. Student performance and attitudes improved as a result of the …

Orbital Separation Amplification In Fragile Binaries With Evolved Components, K. B. Johnston, Terry D. Oswalt

Publications

The secular stellar mass-loss causes an amplification of the orbital separation in fragile, common proper motion, binary systems with separations of the order of 1000 A.U. In these systems, companions evolve as two independent coeval stars as they experience negligible mutual tidal interactions or mass transfer. We present models for how post-main sequence mass-loss statistically distorts the frequency distribution of separations in fragile binaries. These models demonstrate the expected increase in orbital seapration resulting from stellar mass-loss, as well as a perturbation of associated orbital parameters. Comparisons between our models and observations resulting from the Luyten survey of wide visual …

The Stellar-Activity–Rotation Relationship And The Evolution Of Stellar Dynamos, Nicholas J. Wright, Jeremy J. Drake, Eric E. Mamajek, Gregory W. Henry

Information Systems and Engineering Management Research Publications

We present a sample of 824 solar and late-type stars with X-ray luminosities and rotation periods. This is used to study the relationship between rotation and stellar activity and derive a new estimate of the convective turnover time. From an unbiased subset of this sample the power-law slope of the unsaturated regime, LX/Lbol∝Roβ, is fit as β = −2.70 ± 0.13. This is inconsistent with the canonical β = −2 slope to a confidence of 5σ, and argues for an additional term in the dynamo number equation. From a simple scaling analysis this implies ΔΩ/Ω∝Ω0.7, i.e., the differential rotation of …

Transition From Static To Dynamic Macroscopic Friction In The Framework Of The Frenkel-Kontorova Model, Naum I. Gershenzon, Gust Bambakidis

Physics Faculty Publications

A new generation of experiments on dry macroscopic friction has revealed that the transition from static to dynamic friction is essentially a spatially and temporally non-uniform process, initiated by a rupture-like detachment front. We show the suitability of the Frenkel-Kontorova model for describing this transition. The model predicts the existence of two types of detachment fronts, explaining both the variability and abrupt change of velocity observed in experiments. The quantitative relation obtained between the velocity of the detachment front and the ratio of shear to normal stress is consistent with experiments. The model provides a functional dependence between slip velocity …

The Effect Of Oxidation And Support On Tio2(110)-Supported Pdn (N=1-7) Clusters, S. Vincent Ong

Theses and Dissertations

First principles theoretical studies based on a gradient-corrected density functional approach have been carried out on the atomic and electronic properties and oxidation of Pdn (n=1-7) clusters supported on the TiO2(110) surface. The studies are aimed to address some of the fundamental issues related to the properties of supported Pdn clusters used as catalysts in oxidation reactions. Of those issues are the following: What are the atomic structures of Pdn clusters on the TiO2 surface? Upon oxidation, do O atoms from a dissociated O2 molecule spill over onto the underlying TiO2 sup- port? How strongly does spillover oxygen bind? What …

Synthesis And Characterizations Of Novel Solid Polymer Electrolytes With Carbon Nanotube As A Filler / Suriani Ibrahim, Ibrahim Suriani

Student Works (2010-2019)

Nanocomposite solid polymer electrolyte based on poly (ethylene oxide) (PEO) as a host matrix, doped with lithium hexaflurophosphate (LiPF6) salt, plasticized with ethylene carbonate (EC) and dispersed with amorphous carbon nanotubes (αCNTs) as nanocomposite filler were prepared by solution-casting technique. The polymer electrolytes were characterized by Impedance Spectroscopy (IS) to obtain the composition of additives which gives the highest conductivity value for each system. At room temperature, the highest conductivity was found to be 1.30 × 10-3 Scm-1 with a composition of PEO - 20wt% LiPF6 - 15wt%EC and αCNTs - 5wt%. The ionic conductivities of the nanocomposite polymer electrolytes …

Circular And Near-Circular Polarization States Of Evanescent Monochromatic Light Fields In Total Internal Reflection, R. M. A Azzam

Electrical Engineering Faculty Publications

Conditions for the production of near-circular polarization states of the evanescent field present in the rarer medium in total internal reflection of incident monochromatic p-polarized light at a dielectric-dielectric planar interface are determined. Such conditions are satisfied if high-index (>3.2) transparent prism materials (e.g., GaP and Ge) are used at angles of incidence well above the critical angle but sufficiently below grazing incidence. Furthermore, elliptical polarization of incident light with nonzero p and s components can be tailored to cause circular polarization of the resultant tangential electric field in the plane of the interface or circular polarization of the …
