In this thesis I rethink the materiality of rhetoric in a minor key. I review poststructural and psychoanalytic endeavors to position rhetoric from within the postmodern and poststructural critique of the subject. I move beyond the logic of influence (dependent on a flawed conception of object) and hermeneutics (the correspondingly flawed methodology). In this endeavor, I primarily enlist Deleuze and Guattari (1987) for a conceptual apparatus that enlivens the "thinness" of rhetoric's (neo)Aristotelian conceptual design (cf. Gaonkar, 1997a, 1997b). I offer Monster (2003) as a case study, analyzing the discursive expression of nondiscursive abstract machines to draw out the reterritorializations of the latter. Recognizing the impossibility of complete reterritorialization I map one artifact that reinvests difference in itself, Dancer in the Dark (2000). Finally, in the epilogue I provide a brief recapitulation of minor politics, and offer a summarization of the utility of rhetoric.

This thesis will examine the iconography of late-thirteenth- through fifteenth-century images of St. Veronica's veil, also known as vernicles. In the late Middle Ages, vernicle iconography changed from iconic representations of Christ's face toward graphic imagery of Christ's suffering during his Passion. These passionate transformations, as I have called them, were affected by the Roman Sudarium relic, popular devotion to Christ's suffering and humanity during his Passion, and the Catholic ritual of Mass. This thesis will consider how the function of vernicle images during Mass was reflected in their iconography throughout Europe between 1250 and 1500.

Designing 802.11 wireless networks includes two major components: selection of access points (APs) in the demand areas and assignment of radio frequencies to each AP. Coverage and capacity are some key issues when placing APs in a demand area. APs need to cover all users. A user is considered covered if the power received from its corresponding AP is greater than a given threshold. Moreover, from a capacity standpoint, APs need to provide certain minimum bandwidth to users located in the coverage area. A major challenge in designing wireless networks is the frequency assignment problem. The 802.11 wireless LANs operate in the unlicensed ISM frequency, and all APs share the same frequency. As a result, as 802.11 APs become widely deployed, they start to interfere with each other and degrade network throughput. In consequence, efficient assignment of channels becomes necessary to avoid and minimize interference. In this work, an optimal AP selection was developed by balancing traffic load. An optimization problem was formulated that minimizes heavy congestion. As a result, APs in wireless LANs will have well distributed traffic loads, which maximize the throughput of the network. The channel assignment algorithm was designed by minimizing channel interference between APs. The …

When I was first introduced to photography, I was mainly drawn to landscape imagery. I enjoyed being a solitary spectator. Over time, inclusions of figurative elements became more and more apparent in my work. I purposefully began to incorporate a figure into my landscapes, ascribing to it a certain nostalgia and a sense of isolation I was experiencing on many levels at that time. Before long, I felt disconnected from these images because of their ambiguity and generalization. I found myself craving more content and personal commitment in my photography. At the end 2003, I started experimenting with a 4" x 5" format camera, which forced me, to some extent, to change my way of photographing and seeing. That is how the beginning of this new body of work was born. I was accustomed to shooting with a 35 mm camera, which allowed me to be spontaneous, quick and immediate. I permanently switched to a large format. I could see myself benefiting from this change. I lost some of the spontaneity that a 35 mm format offers but I gained the beauty of working with larger negatives and the endless possibilities of view camera movements. Thanks to this technical transformation, …

The following paper reveals some aspects of my thoughts about art. The works discussed are featured in my M.F.A. exhibition. All works are mainly based on the ideas of absence, self-reference and utilization in art practice, even though each piece approaches the subject from differing angles. My dissatisfaction with preconceived notions in the contemporary art, rooted in art history, has shifted my focus from concerns of the direct, physical presence of artworks to the indirect or indecisive elements of their context. From this position I have felt free to explore the paradox of self-reference that is involved in performance. In addition, by transferring art works to functional objects, I have found a way to infuse everyday life with my art, and vice-versa. The ambiguity of interpreting artworks with language means that I present this paper with photographic documentation of my artwork. Combined, this will give a clear indication of the thrust of my graduate studies and the current theatrical direction of my art.

Thermodynamical formalism is a relatively recent area of pure mathematics owing a lot to some classical notions of thermodynamics. On this thesis we state and prove some of the main results in the area of thermodynamical formalism. The first chapter is an introduction to ergodic theory. Some of the main theorems are proved and there is also a quite thorough study of the topology that arises in Borel probability measure spaces. In the second chapter we introduce the notions of topological pressure and measure theoretic entropy and we state and prove two very important theorems, Shannon-McMillan-Breiman theorem and the Variational Principle. Distance expanding maps and their connection with the calculation of topological pressure cover the third chapter. The fourth chapter introduces Gibbs states and the very important Perron-Frobenius Operator. The fifth chapter establishes the connection between pressure and geometry. Topological pressure is used in the calculation of Hausdorff dimensions. Finally the sixth chapter introduces the notion of conformal measures.

Adherent Cu films were electrodeposited onto polycrystalline W foils from purged solutions of 0.05 M CuSO4 in H2SO4 supporting electrolyte and 0.025 M CuCO3∙Cu(OH)2 in 0.32 M H3BO3 and corresponding HBF4 supporting electrolyte, both at pH = 1. Films were deposited under constant potential conditions at voltages between -0.6 V and -0.2 V vs Ag/AgCl. All films produced by pulses of 10 s duration were visible to the eye, copper colored, and survived a crude test called "the Scotch tape test", which stick the scotch tape on the sample, then peel off the tape and see if the copper film peels off or not. Characterization by scanning electron microscopy (SEM), energy dispersive X-ray (EDX) and X-ray photon spectroscopy (XPS) confirmed the presence of metallic Cu, with apparent dendritic growth. No sulfur impurity was observable by XPS or EDX. Kinetics measurements indicate that the Cu nucleation process in the sulfuric bath is slower than in the borate bath. In both baths, nucleation kinetics do not correspond to either instantaneous or progressive nucleation. Films deposited from 0.05 M CuSO4/H2SO4 solution at pH > 1 at -0.2 V exhibited poor adhesion and decreased Cu reduction current. In both borate and sulfate baths, small …

Cubic boron nitride (cBN) synthesis has gained lot of interest during the past decade as it offers outstanding physical and chemical properties like high hardness, high wear resistance, and chemical inertness. Despite of their excellent properties, every application of cBN is hindered by high compressive stresses and poor adhesion. The cost of equipment is also high in almost all the techniques used so far. This thesis deals with the synthesis of cubic phase of boron nitride on Si (100) wafers using electron beam evaporator, a low cost equipment that is capable of depositing films with reduced stresses. Using this process, need of ion beam employed in ion beam assisted processes can be eliminated thus reducing the surface damage and enhancing the film adhesion. Four sets of samples have been deposited by varying substrate temperature and the deposition time. scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS), and Fourier transform infrared spectroscopy (FTIR) techniques have been used to determine the structure and composition of the films deposited. X-ray diffraction (XRD) was performed on one of the samples to determine the thickness of the film deposited for the given deposition rate. Several samples showed dendrites being formed as …

Non-profits are increasing in size and scope to meet social needs that are unmet by the government. Declining financial support, government regulations, and increasing competition force non-profits to become more professional and efficient. Non-profits increasingly engage in commercial activities, joint ventures with for-profits, and employ business techniques such as business planning and marketing. An extensive body of research examines issues related to non-profit performance that supplies a framework for business planning. Business planning may help non-profits to sustain competitive advantages and long-term financial stability. This paper examines the challenges of writing a business plan for non-profits concluding with a sample business plan that takes into consideration advantages, risks, and limitations of non-profits.

Informed by the methodology utilized in Peter Williams's Houses of God: Region, Religion, and Architecture in the United States (1997), the thesis examines Mark Lemmon's Gothic Revival design for the Highland Park Presbyterian Church (1941) with special attention to the denomination and social class of the congregation and the architectural style of the church. Beginning with the notion that Lemmon's church is more complex than an expression of the Southern cultural region defined by Williams, the thesis presents the opportunity to examine the church in the context of the unique cultural region of the city of Dallas. Church archival material supports the argument that the congregation deliberately sought to identify with both the forms and ideology of the late nineteenth-century Gothic Revival in the northeastern United States, a result of the influence of Dallas's cultural region.

The thesis studied quantized conductance in nanocontacts formed between two thin gold wires with one of the wires coated by alkainthiol self assembly monolayers (SAM), by using the cross-wire junction. Using the Lorenz force as the driving force, we can bring the two wires in contact in a controlled manner. We observed conductance with steps of 2e2 / h. The conductance plateaus last several seconds. The stability of the junction is attributed to the fact that the coating of SAM improves the stability and capability of the formed contact.

The Internet became a standard way of exchanging business data between B2B and B2C applications and with this came the need for providing various services on the web instead of just static text and images. Web services are a new type of services offered via the web that aid in the creation of globally distributed applications. Web services are enhanced e-business applications that are easier to advertise and easier to discover on the Internet because of their flexibility and uniformity. In a real life scenario it is highly difficult to decide which J2EE application server to go for when deploying a enterprise web service. This thesis analyzes the various ways by which web services can be developed & deployed. Underlying protocols and crucial issues like EAI (enterprise application integration), asynchronous messaging, Registry tModel architecture etc have been considered in this research. This paper presents a report by analyzing what various J2EE application servers provide by doing a case study and by developing applications to test functionality.

Glutathione syntethase (GS) is an enzyme that belongs to the ATP-grasp superfamily and catalyzes the second step in the biosynthesis of glutathione. GS has been purified and sequenced from a variety of biological sources; still, its exact mechanism is not fully understood. Four highly conserved residues were identified in the binding site of human GS. Additionally, the G-loop residues that close the active site during catalysis were found to be conserved. Since these residues are important for catalysis, their function was studied computationally by site-directed mutagenesis. Starting from the reported crystal structure of human GS, different conformations for the wild type and mutants were obtained using molecular dynamics technique. The key interactions between residues and ligands were detected and found to be essential for enzyme activity.

The purpose of this study was to examine the effect of a breastfeeding education program on breastfeeding initiation rates, breastfeeding knowledge, and attitude towards breastfeeding among teenage mothers at an urban school for pregnant and parenting teens. Breastfeeding initiation rose from 35.7% in the control group to 85.2% in the treatment group. The mean score on the Breastfeeding Knowledge Subscale was significantly higher for the treatment group but not the control group. There was not a significant increase in mean scores on the Breastfeeding Attitude Subscale. Participants who initiated breastfeeding scored also had a significant increase in scores from pretest to posttest on the Breastfeeding Knowledge Subscale, while participants who did not initiate breastfeeding did not.

I experimented with Hopfield networks in the context of a voice-based, query-answering system. Hopfield networks are used to store and retrieve patterns. I used this technique to store queries represented as natural language sentences and I evaluated the accuracy of the technique for error correction in a spoken question-answering dialog between a computer and a user. I show that the use of an auto-associative Hopfield network helps make the speech recognition system more fault tolerant. I also looked at the available encoding schemes to convert a natural language sentence into a pattern of zeroes and ones that can be stored in the Hopfield network reliably, and I suggest scalable data representations which allow storing a large number of queries.

The purpose of this paper is to analyze and identify the major factors that determine the success or failure of mega-sports events. The report begins with a discussion of why localities are willing to invest large sums of public monies in infrastructure and services to host these events. This is followed by a review of the methods used to assess the economic, fiscal, and social impacts of hosting large sporting events. It is observed that comprehensive analyses of the impacts of these events are not undertaken. Finally, the major factors that affect the success of these events are discussed along with suggestions for improving studies evaluating success or failure.

This project consists of an original composition, Voci Lontani, and a critical essay about the composition. In this piece, the idea of musical simultaneity is explored. Therefore, the piece focuses on the idea of contrast: between measured rhythms and indeterminate rhythms, between tonality and atonality, and between musics in separate tempos. In order to explore the significance of musical simultaneity, four important compositional concepts-the simultaneous juxtaposition of different musics, polyrhythmic structure, controlled indeterminacy, and quotation-are discussed. Also, several examples of twentieth-century music that use these concepts are analyzed in the essay.

The ability to passivate metallic surfaces under non-UHV conditions is not only of fundamental interests, but also of growing practical importance in catalysis and microelectronics. In this work, the passivation effect of a surface iodine layer on air-exposed Ta for the copper electroless deposition was investigated by X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM). Although the passivation effect was seriously weakened by the prolonged air exposure, iodine passivates the Ta substrate under brief air exposure conditions so that enhanced copper wetting and adhesion are observed on I-passivated Ta relative to the untreated surface.

The human opportunistic pathogen, Pseudomonas aeruginosa PAO1, has been shown to kill the nematode Caenorhabditis elegans. C. elegans has been a valuable model for the study of bacterial pathogenesis, and has reinforced the notion that common virulence and host defense mechanisms exist. Recently, the pyrimidine pathway was shown to regulate virulence levels. Therefore, mutations in the pyrimidine pathway of PAO1 showed decrease virulence in the nematode. When starving the nematode, bacterial resistance was also shown to increase. It was hypothesized that starvation induced the DAF pathway, which regulates the transcription of genes involved with the antibacterial defense mechanism. Further research will be conducted to test this theory by performing RNAi experiments for the genes functioning in the antibacterial defense mechanism.

The growing number of terrorist attacks waged by Islamic fundamentalists has led to an increasing desire to understand the nature of jihad. These attacks have led to a renewed sense of urgency to find answers to such questions as why these attacks occur, and who they are waged against. Towards this end I turn to examine the political philosophy of four Muslim theologians. Specifically I look at the political philosophy of Sayyid Qutb, Shah Walai Allah Dihlawai, Ibn Rushd (Averroes), and Muhammad Sa'id al-Ashmawy. I find that the notion of jihad is very inconclusive. Furthermore, the question of jihad revolves largely around the question of whether or not individuals can be reasoned with, and secondly whether religion should be compelled upon individuals.
