Open-Access Crime Maps As Digital Rhetoric And Crime Reporting In Chicago: Using New Aesthetic Overlaps To Change Journalism And Citizen Interaction, Aaron Geiger
Graduate Theses, Dissertations, and Problem Reports (ETD)
When data mining meets the rhetoric of maps and crowdsourcing in the age of digital journalism, we can use the abundance of data to change, modify or reinforce particular reporting behaviors or journalism policies. We also live in an age of overlapping boundaries of technologies, algorithms and human interfaces---it is within these overlaps that we find anomalies, "glitches", and digital errata that can expose different perceptions of the same artifacts and algorithms. The overlapping of the heterogeneous network, as James Bridle calls it, is known as The New Aesthetic. It is not a movement, but "a series of artifacts ... …
On The Matroid Intersection Conjecture, Shadisadat Ghaderi
On The Matroid Intersection Conjecture, Shadisadat Ghaderi
Graduate Theses, Dissertations, and Problem Reports (ETD)
In this dissertation, we investigate the Matroid Intersection Conjecture for pairs of matroids on the same ground set, proposed by Nash-Williams in 1990. Originally, the conjecture was stated for finitary matroids only, but we consider it for general matroids and introduce new approaches to attack the conjecture.;The first approach is to consider the situation when it is possible to make a finite modification to the matroids after which the pair satisfies the conjecture. In such a situation we say that the pair has the Almost Intersection Property. We prove that any pair of matroids with the Almost Intersection Property must …

Stochastic Geometry Analysis Of A Class Of Cooperative Relaying Protocols, Sri Lakshmi Phani Balineni
Stochastic Geometry Analysis Of A Class Of Cooperative Relaying Protocols, Sri Lakshmi Phani Balineni
Graduate Theses, Dissertations, and Problem Reports (ETD)
This thesis examines wireless relay networks that use hybrid-ARQ protocols. Relays networks efficiently combat fading and exploit the spatial diversity present in the channel. Hybrid-ARQ involves retransmitting the signal if it is not decoded correctly. In conventional HARQ, the retransmission comes from the source, but in cooperative HARQ the retransmission could come from a relay that has successfully decoded the message, thus attaining transmit diversity.;A Markov chain model is conceived and used to compute the effective throughput and outage probability in the presence of Rayleigh fading. The analytical results are validated with simulations. The spatial configuration of the network plays …

Graduate Theses, Dissertations, and Problem Reports (ETD)
Red spruce restoration efforts in the central Appalachians are of interest to land managers because of the reduced current extent and the numerous ecosystem services provided by red spruce forests. These land managers require information regarding the best places to focus restoration efforts. Studies attempting to locate optimal locations for red spruce restoration have been conducted to in the central Appalachians, most of which utilize modeling. In particular, podzolization, a soil formation pathway present under conifer vegetation in the central Appalachians has been used to help select areas for red spruce restoration. The effectiveness of using recent podzolization (as evidenced …

Now more than ever American adolescents are suffering from severe anxiety (Lewis, 2017). In the past, over-achieving students were those parents least worried about when it came to experiencing anxiety but now studies show these students are just as likely to experience anxiety as those learners considered to be underachievers. The purpose of this paper is to inform the reader how art therapy approaches embedded into daily lesson plans could be used in alternative learning school settings to help students deal with anxiety. Through my own experiences as a practicing art teacher in both general education art classrooms and alternative …
Three Essays On Trade And Local Labor Markets, Sandeep Sharma
Three Essays On Trade And Local Labor Markets, Sandeep Sharma
Graduate Theses, Dissertations, and Problem Reports (ETD)
This dissertation studies the effect of trade on wage dispersion, crime rates and alcohol consumption at the local labor market level in the the U.S. The first chapter develops a new measure for skill to investigate the effects of offshoring on wages of three types of workers: high-skilled, medium-skilled, and low-skilled. I also look at the effect of offshoring on wages of offshorable occupations. Although the previous literature emphasizes the impact of offshoring on the skill premium, I find that job characteristics such as offshorability is critical in explaining the wage effect. Chapter 2 analyzes the effects of increasing import …

A Characterization Of Laminar And Turbulent Boundary Layers For Use In An Investigation Of Boundary Layer State Effects On Turbine Blade Film Colling Schemes, Christopher Michael Nestor
Graduate Theses, Dissertations, and Problem Reports (ETD)
The boundary layer region of a flow is a primary area of interest when analyzing the effects of various flow phenomena, heat transfer, and skin friction near an immersed object's surface. Characterizing this region yields a proper understanding of mass, momentum, and energy transfer to or from the region near the immersed body surface. Such characterization includes the boundary layer height, displacement, and momentum boundary layer thicknesses among many attributes. These factors offer a description of the flow for a laminar state, but also must include length scales, turbulence intensities, and distribution of turbulent kinetic energy to fully describe a …

A Study In Songs: Comparative Analyses Of 20th Century Settings Of William Blake's "Songs Of Innocence And Of Experience": Selections From Vaughan Williams's "Ten Blake Songs", Britten's "Songs And Proverbs Of William Blake", And Rochberg's "Blake Songs: For Soprano And Chamber Ensemble", Jennifer Berkebile
Graduate Theses, Dissertations, and Problem Reports (ETD)
The eighteenth-century poet, William Blake, is well-known today for his illuminated books, where a unique technique of relief etching allowed him to integrate text and illustration on a single printed copper plate, and his esoteric prophetic volumes. However, Blake's work went largely unrecognized during his lifetime and musical settings of Blake's poetry, in particular, are predominantly a twentieth and twenty-first century occurrence. With their distinctive styling and complicated interpretation, Blake's Songs of Innocence and Experience: Shewing the Two Contrary States of the Human Soul have provided material for many song settings over the course of the twentieth century and make …

Correlating Metastable-Atom Density, Reduced Electric Field, And Electron Energy Distribution In The Initiation, Transient, And Post-Transient Stages Of A Pulsed Argon Discharge, James B. Franek
Graduate Theses, Dissertations, and Problem Reports (ETD)
Argon emission lines, particularly those in the near-infrared region (700-900nm), are used to determine plasma properties in low-temperature, partially ionized plasmas to determine effective electron temperature [Boffard et al., 2012], and argon excited state density [Boffard et al., 2009] using appropriately assumed electron energy distributions. While the effect of radiation trapping influences the interpretation of plasma properties from emission-line ratio analysis, eliminating the need to account for these effects by directly observing the 3px-to-1sy transitions [ Boffard et al., 2012] is preferable in most cases as this simplifies the analysis. In this dissertation, a 1-Torr argon, pulsed positive column in …
Robust Specularity Removal From Hand-Held Videos, Priyaankadevi Guggilapu
Robust Specularity Removal From Hand-Held Videos, Priyaankadevi Guggilapu
Graduate Theses, Dissertations, and Problem Reports (ETD)
Specular reflection exists when one tries to record a photo or video through a transparent glass medium or opaque surfaces such as plastics, ceramics, polyester and human skin, which can be well described as the superposition of a transmitted layer and a reflection layer. These specular reflections often confound the algorithms developed for image analysis, computer vision and pattern recognition. To obtain a pure diffuse reflection component, specularity (highlights) needs to be removed. To handle this problem, a novel and robust algorithm is formulated. The contributions of this work are three-fold.;First, the smoothness of the video along with the temporal …

Investigating Stress Response Across Integrated Biological Systems, Alice A. Han
Graduate Theses, Dissertations, and Problem Reports (ETD)
The impact that a stressor has on a living system, whether it is on a cellular, organ, or even a whole organism level, can affect the overall health of the system. Monitoring the biochemical response resulting from a stressful experience offers insight into the numerous potential outcomes ranging on the spectrum of survival and death. Accessing this information not only provides a heightened understanding of the biochemical adaptions that occur, but also allows for the development of prediction models (to assess prospective influences of the stressor) or potential therapeutic treatments (to alleviate adverse effects) using measurable, quantifiable, and comparable metrics. …

Operability-Based Design Of Energy Systems: Application To Natural Gas Utilization Processes, Juan C. Carrasco-Moraga
Graduate Theses, Dissertations, and Problem Reports (ETD)
Process operability emerged in the last decades as a powerful tool for the design and control of complex chemical processes. The design of such processes is a challenging task as they are represented by nonlinear models with large numbers of differential and algebraic equations that demand high computational effort for their solution. In particular, process operability was proposed as a method for verifying the ability of a process design, defined by the available input set, to reach an achievable output set that considers production targets. However, existing operability methods for nonlinear systems are limited by the problem size that they …

Steady-State Co-Kriging Models, Sahar Hemmati
Steady-State Co-Kriging Models, Sahar Hemmati
Graduate Theses, Dissertations, and Problem Reports (ETD)
In deterministic computer experiments, a computer code can often be run at different levels of complexity/fidelity and a hierarchy of levels of code can be obtained. The higher the fidelity and hence the computational cost, the more accurate output data can be obtained. Methods based on the co-kriging methodology Cressie (2015) for predicting the output of a high-fidelity computer code by combining data generated to varying levels of fidelity have become popular over the last two decades. For instance, Kennedy and O'Hagan (2000) first propose to build a metamodel for multi-level computer codes by using an auto-regressive model structure. Forrester …
Economic Activity And The Association Of Spending Rate And Spending Rate Volatility On Borrowing Cost, Anna W. Hickey
Economic Activity And The Association Of Spending Rate And Spending Rate Volatility On Borrowing Cost, Anna W. Hickey
Graduate Theses, Dissertations, and Problem Reports (ETD)
Achieving minimum borrowing cost for municipal bonds is an ongoing concern. Apostolou, Apostolou, and Dorminey (2014) demonstrated that a fund accounting measure, spending rate magnitude (i.e., the absolute value of general fund revenues minus general fund expenditures) proxied for management's ability to balance revenues and expenditures. Their findings indicated that achieving balance at spending rate equilibrium (i.e., where general fund revenues equal general fund expenditures) was associated with minimum borrowing cost, and that the magnitude of departure from spending rate equilibrium was associated with higher borrowing cost. Little is known regarding the information content of spending rate in the years …

Performance Of The Horizontal Wells In A Naturally Fractured Carbonate Reservoir, Fuad Al-Bayati
Graduate Theses, Dissertations, and Problem Reports (ETD)
About 60 percent of the world's proven oil reserves and 40 percent of gas reserves are trapped in carbonate reservoirs. Recovery rates are relatively low in carbonate reservoirs, and it is extremely challenging to predict due to the heterogeneous nature of these reservoirs. The majority of carbonate reservoirs contain fractures which may vary in size from millimeters to kilometers. A typical example of this type of reservoirs is oil and gas fields in the northern Iraq. These fields are almost all developed by vertical wells. This study will investigate the use of horizontal wells to enhance the productivity in one …
