Many organizations such as the Federal Highway Administration (FHWA) and American Association of State Highway and Transportation Officials (AASHTO) are considering intersection safety improvement as one of their top priority areas. This study contributes to the area of safety of signalized intersections by identifying the traffic and geometric characteristics that affect the different types of crashes. The first phase of this thesis was to classify the crashes occurring at signalized intersections into rear-end, angle, turn and sideswipe crash types based on the traffic and geometric properties of …


Optimizing The Performance Of As-Manufactured Grazing Incidence X-Ray Telescopes Using Mosaic Detector Arrays, Martina Atanassova Jan 2005

Optimizing The Performance Of As-Manufactured Grazing Incidence X-Ray Telescopes Using Mosaic Detector Arrays, Martina Atanassova

Electronic Theses and Dissertations

The field of X-ray astronomy is only forty (43) years old, and grazing incidence X-ray telescopes have only been conceived and designed for a little over fifty (50) years. The Wolter Type I design is particularly well suited for stellar astronomical telescopes (very small field-of-view). The first orbiting X-ray observatory, HEAO-1 was launched in 1977, a mere twenty-eight (28) years ago. Since that time large nested Wolter Type I X-ray telescopes have been designed, build, and launched by the European Space Agency (ROSAT) and NASA (the Chandra Observatory). Several smaller grazing incidence telescopes have been launched for making solar observations …

Grassland And Woodland Bird Occurrence And Habitat Selection In The Prairie-Forest Transition Zone Of Minnesota, Thomas Robert Cooper

Electronic Theses and Dissertations

Numerous species of woodland and grassland nesting birds have experienced population declines in the midwestern United States. Habitat loss and habitat fragmentation are suspected to be two of the underlying causes for the population declines of woodland and grassland birds. The Minnesota Valley Wetland Management District (WMD) covers 14 counties in southeastern Minnesota in the transition zone between forested and prairie ecoregions. Little information is available relative to which birds are using grassland or woodland habitat within the WMD and how their presence or absence is related to the available habitat conditions. Therefore, my study objectives were to: 1) determine …

Students with emotional/ behavioral disabilities often have low self-efficacy when it comes to explaining their own disabilities, coping with the label of having a disability, and …


The Us Government-Sponsored Graduate-Level Exchange Programs: The Goals Of The Major Stakeholders And The Students' Academic Interests, Ekaterina Kharlamova Jan 2005

The Us Government-Sponsored Graduate-Level Exchange Programs: The Goals Of The Major Stakeholders And The Students' Academic Interests, Ekaterina Kharlamova

Electronic Theses and Dissertations

A steady increase in student mobility levels has become a widely recognized component of general globalization trends in the modern world. Yet, internationalization of education is not merely a product of bigger globalization processes. Educational exchange, in many instances sponsored and administered by national governments, is an effective tool in governmental foreign policies. The shift of focus in governmental policies towards the political rather than educational purposes of educational international exchange could lead for lack of attention paid to the issues of foreign students' academic interests. At the same time, universities, although prompted by the globalization tendencies to internationalize their …


The Role Of Histidine-Rich Proteins In The Biomineralization Of Hemozoin, Lisa Pasierb Jan 2005

The Role Of Histidine-Rich Proteins In The Biomineralization Of Hemozoin, Lisa Pasierb

Electronic Theses and Dissertations

Hemozoin formation, the consequential end product of the proteolysis of hemoglobin by Plasmodium falciparum, is essentially a biomineralization process whereby toxic free heme is aggregated into an inert crystalline solid, also known as malaria pigment or ß-hematin. The histidine-rich protein II (HPR II), isolated from the digestive vacuole of the parasite, has been implicated in the mediation of this biomineral through the protein's ability to bind heme, aggregate the biomineral, and be effectively inhibited by known antimalarials, including chloroquine. The HRP II sequence, which is comprised of 76% of histidine and alanine residues, has a specific amino acid repeat motif …

The Limits Of Philosophy: Plato's Sophist And Statesman, Mark Brouwer Jan 2005

The Limits Of Philosophy: Plato's Sophist And Statesman, Mark Brouwer

Electronic Theses and Dissertations

Plato's Sophist and Statesman articulate the limits or definition of philosophy. My selective interpretation begins with a problem from Sophist 259e-260a and 252e-253e: Is it possible to express correctly (in logos) the necessary conditions of logos? This is an instance of a universal problem: Is it possible for any expertise to define itself and have expert inspired confidence in this definition? I articulate this universal problem with recourse to Kantian meta-philosophy, Chomsky's generative grammar and Schoenberg's theory of harmony. Rudolph Carnap's distinction between questions internal and external to a scientific framework is the means of addressing this universal problem. Questions …

Participants included 16 eighth grade teachers and 184 eighth grade students. Data were collected through the use of a teacher questionnaire and an anonymous student writing assignment. Teacher and student responses were grouped into emerging themes of caring. The methodology used in this study to analyze the results included calculating and comparing the percentage of teacher and …


Bayesian Hierarchical Modeling For Longitudinal Frequency Data, Joseph Patrick Jordan Jan 2005

Bayesian Hierarchical Modeling For Longitudinal Frequency Data, Joseph Patrick Jordan

Electronic Theses and Dissertations

This research is to develop a longitudinal frequency model for data collected regularly for several individuals over an extended time period. This model must recognize explicitly the discrete nature of the data, as well as any dependence that exists among an individual's time consecutive measurements. Motivated by a study investigating alternative treatments for relief of menopausal symptoms, we apply this model to actual study data in an effort to compare treatment effectiveness. We propose a Bayesian hierarchical model to describe not only frequency measurements, but also the parameters that govern an individual profile.

The literature review showed that providing early intervention services for young children ages 3 through 5 with special needs in the public school system has become the movement of both the federal and state educational policies. However, …


Refractive Indices Of Liquid Crystals And Their Applications In Display And Photonic Devices, Jun Li Jan 2005

Refractive Indices Of Liquid Crystals And Their Applications In Display And Photonic Devices, Jun Li

Electronic Theses and Dissertations

Liquid crystals (LCs) are important materials for flat panel display and photonic devices. Most LC devices use electrical field-, magnetic field-, or temperature-induced refractive index change to modulate the incident light. Molecular constituents, wavelength, and temperature are the three primary factors determining the liquid crystal refractive indices: ne and no for the extraordinary and ordinary rays, respectively. In this dissertation, we derive several physical models for describing the wavelength and temperature effects on liquid crystal refractive indices, average refractive index, and birefringence. Based on these models, we develop some high temperature gradient refractive index LC mixtures for photonic applications, such …


Discrete Wave Propagation In Quadratically Nonlinear Media, Robert Iwanow Jan 2005

Discrete Wave Propagation In Quadratically Nonlinear Media, Robert Iwanow

Electronic Theses and Dissertations

Discrete models are used in describing various microscopic phenomena in many branches of science, ranging from biology through chemistry to physics. Arrays of evanescently coupled, equally spaced, identical waveguides are prime examples of optical structures in which discrete dynamics can be easily observed and investigated. As a result of discretization, these structures exhibit unique diffraction properties with no analogy in continuous systems. Recently nonlinear discrete optics has attracted a growing interest, triggered by the observation of discrete solitons in AlGaAs waveguide arrays reported by Eisenberg et al. in 1998. So far, the following experiments involved systems with third order nonlinearities. …


Deriving The Density Of States For Granular Contact Forces, Philip Metzger Jan 2005

Deriving The Density Of States For Granular Contact Forces, Philip Metzger

Electronic Theses and Dissertations

The density of single grain states in static granular packings is derived from first principles for an idealized yet fundamental case. This produces the distribution of contact forces P_f(f) in the packing. Because there has been some controversy in the published literature over the exact form of the distribution, this dissertation begins by reviewing the existing empirical observations to resolve those controversies. A method is then developed to analyze Edwards' granular contact force probability functional from first principles. The derivation assumes Edwards' flat measure -- a density of states (DOS) that is uniform within the metastable regions of phase space. …
