Earth Sciences

The Sulfur Transport and dEposition Model (STEM) is applied to the analysis of observations obtained during the Intercontinental Chemical Transport Experiment-Phase B (INTEX-B), conducted over the eastern Pacific Ocean during spring 2006. Predicted trace gas and aerosol distributions over the Pacific are presented and discussed in terms of transport and source region contributions. Trace species distributions show a strong west (high) to east (low) gradient, with the bulk of the pollutant transport over the central Pacific occurring between ∼20° N and 50° N in the 2-6 km altitude range. These distributions are evaluated in the eastern Pacific by comparison with …

Numerical Investigation Of Aeroelastic Mode Distribution For Aircraft Wing Model In Subsonic Air Flow, Marianna A. Shubov, Stephen B. Wineberg, Robert Holt

Mathematics & Statistics

In this paper, the numerical results on two problems originated in aircraft wing modeling have been presented. The first problem is concerned with the approximation to the set of the aeroelastic modes, which are the eigenvalues of a certain boundary-value problem. The affirmative answer is given to the following question: can the leading asymptotical terms in the analytical formulas be used as reasonably accurate description of the aeroelastic modes? The positive answer means that these leading terms can be used by engineers for practical calculations. The second problem is concerned with the flutter phenomena in aircraft wings in a subsonic, …

Earth‐Moon‐Mars Radiation Environment Module Framework, Nathan A. Schwadron, L. Townsend, K. Kozarev, M. A. Dayeh, F. Cucinotta, M. Desai, M. Golightly, D. Hassler, R. Hatcher, M. Y. Kim, A. Posner, M. Pourarsalan, Harlan E. Spence, R. K. Squier

Physics & Astronomy

[1] We are preparing to return humans to the Moon and setting the stage for exploration to Mars and beyond. However, it is unclear if long missions outside of low-Earth orbit can be accomplished with acceptable risk. The central objective of a new modeling project, the Earth-Moon-Mars Radiation Exposure Module (EMMREM), is to develop and validate a numerical module for characterizing time-dependent radiation exposure in the Earth-Moon-Mars and interplanetary space environments. EMMREM is being designed for broad use by researchers to predict radiation exposure by integrating over almost any incident particle distribution from interplanetary space. We detail here the overall …

2,3-Bis(Bromomethyl)-1,4-Diphenylbenzene, Jonathan B. Briggs, Mikael D. Jazdzyk, Glen P. Miller

Chemistry

In the title compound, C(20)H(16)Br(2), the terminal phenyl groups are twisted away from the central ring by approximately 55 and -125 degrees (average of four dihedral angles each), respectively. The crystal structure is stabilized by a combination of interMolecular and intraMolecular interactions including interMolecular pi-pi stacking interactions [C atoms of closest contact = 3.423 ( 5) angstrom].

Potential Applications Of Randomised Graph Sampling To Invasive Species Surveillance And Monitoring., Mark J. Ducey, Kathleen M. O'Brien

Natural Resources & the Environment

Abstract

Many invasive plants and animals disperse preferentially through linear networks in the landscape, including road networks, riparian corridors, and power transmission lines. Unless the network of interest is small, or the budget for surveillance is large, it may be necessary to draw inferences from a sample rather than a complete census on the network. Desired features of a surveillance system to detect and quantify invasion include: (1) the ability to make unbiased statements about the spatial extent of invasion, the abundance of the invading organism, and the degree of impact; (2) the ability to quantify the uncertainty associated with …

Algae And Biodiesel: Patenting Energized As Green Goes Commercial, Matthew R. Priess, Stanley P. Kowalski

Law Faculty Scholarship

In the twenty-first century, predominant dependence on fossil fuels as energy resources will not be sustainable. Developing and commercializing green energy innovations will be an essential component of the transition to a more diversified energy economy. Algal biodiesel is one of the most promising green fuels because of its potential as a renewable and sustainable fuel source without displacing food crops. Algal biodiesel research and development are necessary early steps towards a transition to a green energy economy. The strategic use of strong patent portfolios will drive this by attracting investment, incentivizing innovation and accelerating commercialization. Whereas algal biodiesel research …

The Role Of Personal And Contextual Variables In College Students' Academic Achievement, Rachel A. Rogers

Doctoral Dissertations

College matriculation rates are increasing but graduation rates are failing to parallel the increased enrollment. One reason for this discrepancy may be that many college students are unable to regulate their own learning. This dissertation examined the Self-Regulated Learning (SRL; Pintrich, 2004) model in students taking Statistics in Psychology and Research Methods. The inclusion of the constructs of possible selves and identity development in the SRL model was proposed, as was the Achievement Goal Questionnaire (AGQ; Elliot & McGregor, 2001), a measure of the 2x2 Framework of achievement goal orientation. These variables were assessed along with those included in the …

Bimodule Categories And Monoidal 2-Structure, Justin Greenough

Doctoral Dissertations

We define a notion of tensor product of bimodule categories and prove that with this product the 2-category of C -bimodule categories for fixed tensor C is a monoidal 2-category in the sense of Kapranov and Voevodsky ([KV91]). We then provide a monoidal-structure preserving 2-equivalence between the 2-category of C -bimodule categories and Z( C )-module categories (module categories over the center of C ). The (braided) tensor structure of C1⊠D C2 for (braided) fusion categories over braided fusion D is introduced. For a finite group G we show that de-equivariantization is equivalent to the tensor product over Rep( G). …

The Application Of Computational Modeling To Data Visualization, Daniel S. Pineo

Doctoral Dissertations

Researchers have argued that perceptual issues are important in determining what makes an effective visualization, but generally only provide descriptive guidelines for transforming perceptual theory into practical designs. In order to bridge the gap between theory and practice in a more rigorous way, a computational model of the primary visual cortex is used to explore the perception of data visualizations.

A method is presented for automatically evaluating and optimizing data visualizations for an analytical task using a computational model of human vision. The method relies on a neural network simulation of early perceptual processing in the retina and visual cortex. …

Modeling The Self-Assembly Of Functionalized Fullerenes On Solid Surfaces Using Monte Carlo Simulations, Gregory J. Bubnis

Doctoral Dissertations

Since their discovery 25 years ago, carbon fullerenes have been widely studied for their unique physicochemical properties and for applications including organic electronics and photovoltaics. For these applications it is highly desirable for crystalline fullerene thin films to spontaneously self-assemble on surfaces. Accordingly, many studies have functionalized fullerenes with the aim of tailoring their intermolecular interactions and controlling interactions with the solid substrate.

The success of these rational design approaches hinges on the subtle interplay of intermolecular forces and molecule-substrate interactions. Molecular modeling is well-suited to studying these interactions by directly simulating self-assembly. In this work, we consider three different …

Conjecturing In Dynamic Geometry: A Model For Conjecture-Generation Through Maintaining Dragging, Anna Baccaglini-Frank

Doctoral Dissertations

The purpose of this research is to study aspects of the impact of Dynamic Geometry Systems (DGS) in the process of producing conjectures in Euclidean geometry. Previous research has identified and classified a set of dragging schemes spontaneously used by students. Building on these findings, the study focuses on cognitive processes that arise in correspondence to particular dragging modalities in Cabri. Specifically, we have conceived a model describing what seems to occur during a process of conjecture-generation that involves the use of a particular dragging modality, described in the literature as dummy locus dragging. In order to accomplish this goal, …

The Impact Of A Mathematics Research Experience On Teachers' Conceptions Of Student Learning, Todd Abel

Doctoral Dissertations

Many mathematics teacher professional development programs have either incorporated or been organized around a goal of providing "research-like" (Cuoco, 2001) experiences. That is, teachers participate in a project that somehow simulates the mathematics research process. Though some research studies have shown positive outcomes from such programs, researchers have cautioned against assuming universally positive benefits without sufficient evidence (Proulx and Bednarz, 2001). Teacher conceptions of student learning play an important role in lesson development and preparation for classroom work (Penso & Shoham, 2003). Similarities between the processes of mathematics research and student learning (Dreyfus, 1991) beg the question of whether experience …

Microstructural Evolution Of Sputtered Phase Segregated Metal Composite Thin Films, Dana I. Filoti

Doctoral Dissertations

In this thesis, we present the first comparative study of crystallographic texture development in three different types of metal thin film composites: fully miscible (Au-Ag), slightly immiscible (Cu-Ag) and immiscible (Au-SiO 2). Texture development refers to the distribution of orientations of crystallites in polycrystalline thin films, and is an important part of the microstructure that determines thin film properties. A material's crystallographic texture needs to be understood because of its sensitivity to the energetic growth conditions. By controlling the microstructure, a material can be tailored to specific applications. We investigated in comparison the texture and microstructure evolution in metal composite …

Educator Perceptions Of Policies That May Impact Black Male High School Persistence, L Antonio Henley

Doctoral Dissertations

This study purposed to identify educators' perceptions about the academic state of Black males, explore the influence of policies on Black males' high school persistence, and examine differences in educator perceptions with regards to the impact of education policies on African American males. Findings indicate that educators believe that Black males are doing poorly academically and educators are concerned about the academic progress of Black males. Also, educators do not to believe that the majority of policies identified in this research have any significant impact on the high school persistence of Black males. Further, there are significant differences in educators' …

Topics In Access, Storage, And Sensor Networks, Swapnil Bhatia

Doctoral Dissertations

In the first part of this dissertation, Data Over Cable Service Interface Specification (DOCSIS) and IEEE 802.3ah Ethernet Passive Optical Network (ETON), two access networking standards, are studied. We study the impact of two parameters of the DOCSIS protocol and derive the probability of message collision in the 802.3ah device discovery scheme. We survey existing bandwidth allocation schemes for EPONs, derive the average grant size in one such scheme, and study the performance of the shortest-job-first heuristic.

In the second part of this dissertation, we study networks of mobile sensors. We make progress towards an architecture for disconnected collections of …

Computational And Experimental Studies Of Acenes, Starphenes And [60]Fullerene Derivatives, Ryan Paul Kopreski

Doctoral Dissertations

The computational and experimental studies of acenes, starphenes and [60]fullerene derivatives is described. Acenes are promising organic semiconductors. Hybrid density functional theory applying a triple-zeta valence basis set (B3LYP/6-311+G**) has been used to approximate the HOMO - LUMO excitation gap in various substituted pentacenes. This technique may, in part, synthetically guide substitution patterns of pentacenes and larger acenes. Previous predictions of an open-shell singlet diradical ground state for acenes larger than hexacene have been reproduced and sulfur substitution has been found to alter the electronic ground state to a closed-shell configuration. Substituents that may engage in non-bonding interactions are not …

Von Neumann Algebras, Affiliated Operators And Representations Of The Heisenberg Relation, Zhe Liu

Doctoral Dissertations

Von Neumann algebras are self-adjoint, strong-operator closed subalgebras (containing the identity operator) of the algebra of all bounded operators on a Hilbert space. Factors are von Neumann algebras whose centers consist of scalar multiples of the identity operator. In this thesis, we study unbounded operators affiliated with finite von Neumann algebras, in particular, factors of Type II1. Such unbounded operators permit all the formal algebraic manipulations used by the founders of quantum mechanics in their mathematical formulation, and surprisingly, they form an algebra. The operators affiliated with an infinite von Neumann algebra never form such an algebra. The Heisenberg commutation …

Navigating The Cultural Gaps: Whiteness And Diversity In Two Elementary School Classrooms, Rachel Parse Johnson

Doctoral Dissertations

This study asked how two white, in-service elementary school teachers within the context of their classrooms navigated the cultural gaps between themselves and students from whom they differed (e.g. racially, ethnically, socio-economically, and/or linguistically). Three sub-questions examined: 1) what life experiences shaped how the teachers understood difference and diversity within their classrooms; 2) what system(s) of beliefs the teachers learned and constructed through those experiences; and 3) what identities the teachers assumed and/or assigned to themselves and their students. The study employed a sociocultural theoretical framework. Ethnographic data collection strategies included participant observation, semi-structured interviews, and material collection. Discourse analysis …

Spatial Management Of Groundfish Resources In The Gulf Of Maine And Georges Bank, Jamie Marie Cournane

Doctoral Dissertations

In the marine environment, studies suggest that overfishing suppresses sustainability and resilience in fish populations. In the 1990s, the National Marine Fisheries Service (NMFS) implemented five large year-round fishery closures in the Gulf of Maine and Georges Bank. These closures are partially protected marine protected areas (MPAs) restricting commercial fishing with bottom-tending gears. To date, evaluation of their performance has focused on the productivity of individual species.

This research aims to understand if fish biodiversity changed after implementation of the five large fisheries closures. Here, a variety of datasets and statistical approaches are used.

Modern patterns constructed from NMFS bottom-trawl …

Admissible Orders On Quotients Of The Free Associative Algebra, Jeremiah William Johnson

Doctoral Dissertations

An admissible order on a multiplicative basis of a noncommutative algebra A is a term order satisfying additional conditions that allow for the construction of Grobner bases for A -modules. When A is commutative, a finite reduced Grobner basis for an A -module can always be obtained, but when A is not commutative this is not the case; in fact in many cases a Grobner basis theory for A may not even exist.

E. Hinson has used position-dependent weights, encoded in so-called admissible arrays, to partially order words in the free associative algebra in a way which produces a length-dominant …

Mf Algebras And A Bishop -Stone -Weierstrass Theorem Result, Qihui Li

Doctoral Dissertations

This dissertation consists of two parts. In the first part, we obtain many new results about MF algebras. First, we continue the work on D. Voiculescu's topological free entropy dimension deltatop (x1, ..., xn) for an n-tuple x&ar; = (x1, ..., xn) of elements in a unital C*-algebra. We also introduce a new invariant that is a C*-algebra analog of the invariant K3 introduced for von Neumann algebras. Second, we discuss a full amalgamated free product of unital MF (and residually finite-dimensional) algebras with amalgamation over a finite-dimensional C*-subalgebra. Necessary and sufficient conditions are given in this situation. In the …
