The Aesthetics Of Magnetic Resonance Imaging (Mri): From The Scientific Laboratory To An Artwork, Silvia Casini Jan 2010

The Aesthetics Of Magnetic Resonance Imaging (Mri): From The Scientific Laboratory To An Artwork, Silvia Casini

Contemporary Aesthetics (Journal Archive)

This article investigates the aesthetic potential of Magnetic Resonance Imaging (MRI), a medical imaging technique, both inside the laboratory and in the arts. By combining Rancière’s understanding of aesthetics with Merleau-Ponty’s notion of embodied perception, it argues that an image-generating technique conceived in the scientific field can successfully migrate into the realm of fine art, opening up new aesthetic and perceptual possibilities. Although aesthetic qualities are already present in the laboratory, they remain hidden by the necessity of reading the image-data obtained according to the interpretative framework of the medical discourse. Two paths are covered: the first goes from the …

Characterization And Correction Of Dark Current In Compact Consumer Cameras, Justin Charles Dunlap, Erik Bodegom, Ralf Widenhorn Jan 2010

Characterization And Correction Of Dark Current In Compact Consumer Cameras, Justin Charles Dunlap, Erik Bodegom, Ralf Widenhorn

Physics Faculty Publications and Presentations

A study of dark current in digital imagers within consumer grade digital cameras is presented. Dark current is shown to vary with temperature, exposure time, and ISO setting. Further, dark current is shown to increase in successive images during a series of images. Consumer cameras are often designed to be as compact as possible and therefore the digital imagers within the camera frame are prone to heat generated by nearby elements within the camera body. It is the scope of this work to characterize the dark current in such cameras and to show that the dark current, in part due …

Study Of The Numerical Modeling Of The Temperature Dependence Of The Dark Current In Charge Coupled Devices, Ralf Widenhorn, Ionel Tunaru, Erik Bodegom, Dan A. Iordache Jan 2010

Study Of The Numerical Modeling Of The Temperature Dependence Of The Dark Current In Charge Coupled Devices, Ralf Widenhorn, Ionel Tunaru, Erik Bodegom, Dan A. Iordache

Physics Faculty Publications and Presentations

As it is well known, the classical works of the Dark Current Spectroscopy method allow - using some not too accurate theoretical relations, but huge numbers of dark current values for thousands of pixels - the evaluation of a reduced number of basic impurities parameters. Unlike these works, this paper tries to obtain--by means of some better approximations of the Shockley-Read-Hall (SRH) model--more information about the studied impurities, as well as the study of the compatibility of the used theoretical model SRH relative to the experimental data. In this manner, both the compatibility SRH model with the studied experimental data …

A New Technique For Firn Grain-Size Measurement Using Sem Image Analysis, N.E. Spaulding, D.A. Meese, I. Baker, P.A. Mayewski Jan 2010

A New Technique For Firn Grain-Size Measurement Using Sem Image Analysis, N.E. Spaulding, D.A. Meese, I. Baker, P.A. Mayewski

Dartmouth Scholarship

Firn microstructure is accurately characterized using images obtained from scanning electron microscopy (SEM). Visibly etched grain boundaries within images are used to create a skeleton outline of the microstructure. A pixel-counting utility is applied to the outline to determine grain area. Firn grain sizes calculated using the technique described here are compared to those calculated using the techniques of Gow (1969) and Gay and Weiss (1999) on samples of the same material, and are found to be substantially smaller. The differences in grain size between the techniques are attributed to sampling deficiencies (e.g. the inclusion of pore filler in the …

Climate Change And Freshwater Resources In Oregon, Heejun Chang, Julie Jones Jan 2010

Climate Change And Freshwater Resources In Oregon, Heejun Chang, Julie Jones

Institute for Sustainable Solutions Publications and Presentations

Climate change will affect various sectors of water resources in Oregon in the 21st century. The observed trends in streamflow show significant declines in September flow and, although not significant, increases in March flow in many transient rain-snow basins. These streamflow trends are associated with rising temperature and coincident declines in snowpack in spring in the latter half of the 20th century. While there are no distinct trends in high precipitation events, such events are associated with climate variability such as ENSO and PDO. Effects of ENSO and PDO are more pronounced at the beginning and end of the wet …

Serum Antibodies To Human Papillomavirus Type 6, 11, 16 And 18 And Their Role In The Natural History Of Hpv Infection In Men, Beibei Lu

USF Tampa Graduate Theses and Dissertations

Our understanding of humoral immune response to human papillomavirus (HPV) infection has been mainly derived from studies in women. Very little is known about humoral immune response to HPV in men. There is also a growing interest in understanding the burden of HPV exposure in the subgroups of the male population, including men who have sex with women (MSW), men who have sex with men (MSM) and men who have sex with both men and women (MSMW). This dissertation was undertaken to understand and characterize humoral immune response, measured by detectable serum antibody IgG, to HPV 6, 11, 16 and …

School Choice At The Crossroads Of Race, Class, And Accountability: An Analysis Of The Effects Of Voluntary School Choice On Elementary Schools In A Large District In The Southeastern United States, Teresa Craig Evans Jan 2010

School Choice At The Crossroads Of Race, Class, And Accountability: An Analysis Of The Effects Of Voluntary School Choice On Elementary Schools In A Large District In The Southeastern United States, Teresa Craig Evans

USF Tampa Graduate Theses and Dissertations

In recent years, the responsibility for the desegregation of American public schools has transitioned from federal court mandates to school board programs and policies. There is widespread belief that this has resulted in the resegregation of schools across the country. One popular policy that is purported to provide the opportunity for voluntary integration, along with accountability for academic quality, is school choice. The purpose of this study was to consider the implications of such a policy in one large school district. There is an extensive body of research exploring who participates in school choice, how they make their choices, and …

Symbolic Structures As Systems: On The Near Isomorphism Of Two Religious Symbols, Martin Zwick Jan 2010

Symbolic Structures As Systems: On The Near Isomorphism Of Two Religious Symbols, Martin Zwick

Complex Systems Faculty Publications and Presentations

Many symbolic structures used in religious and philosophical traditions are composed of “elements” and relations between elements. Similarities between such structures can be described using the systems theoretic idea of “isomorphism.” This paper demonstrates the existence of a near isomorphism between two symbolic structures: the Diagram of the Supreme Pole of Song Neo-Confucianism and the Kabbalistic Tree of medieval Jewish mysticism. The similarities of these two symbols in form and meaning are remarkable in the light of the many differences that exist between Chinese and Judaic thought. Intercultural influence might account for these similarities, but there is no historical evidence …

Allowing The Accidental; The Interplay Between Intentionality And Realism In Photographic Art, Katrina Mitcheson Jan 2010

Allowing The Accidental; The Interplay Between Intentionality And Realism In Photographic Art, Katrina Mitcheson

Contemporary Aesthetics (Journal Archive)

We experience photographs both as intentional and as prone to the accidental. The photograph is both capable of being an artwork with its own, constructed world and of drawing our attention to the reality of the objects used in creating it. In this article I employ the insights contained in the concepts of Barthes’ studium and punctum in order to explore how the artist’s intentions and the realism of photography interact aesthetically. I advance the idea that a unique aesthetics of photography can be rooted in the tension between the intentional, culturally coded message of a photograph and the emanation …

The Curatorial Muse, Michael J. Kowalski Jan 2010

The Curatorial Muse, Michael J. Kowalski

Contemporary Aesthetics (Journal Archive)

An appreciation of the tension between the predicate, "to curate," and the subject, "the curator," is essential to understanding the convergence of creation, criticism, and administration in the graphic arts of our time. Curators were ideally positioned to step to the fore when the idea-versus-object dichotomy began to collapse in the work of Duchamp. The roots of activist curating can be found in Western Classical culture. The prevalence of conceptual art at the end of the twentieth century, combined with the explicit denigration of physical craft by artists, created a void into which activist curators moved. The curator's role as …

A Functional Model Of The Aesthetic Response, Daniel Conrad Jan 2010

A Functional Model Of The Aesthetic Response, Daniel Conrad

Contemporary Aesthetics (Journal Archive)

In a process of somatic evolution, the brain semi-randomly generates initially-unstable neural circuits that are selectively stabilized if they succeed in making sense out of raw sensory input. The human aesthetic response serves the function of stabilizing the circuits that successfully mediate perception and interpretation, making those faculties more agile, conferring selective advantage. It is triggered by structures in art and nature that provoke the making of sense. Art is deliberate human action aimed at triggering the aesthetic response in others; thus, if successful, it serves the same function of making perception and interpretation more agile. These few principles initiate …

Extraction Of Small Boat Harmonic Signatures From Passive Sonar, George Lloyd Ogden Jan 2010

Extraction Of Small Boat Harmonic Signatures From Passive Sonar, George Lloyd Ogden

Dissertations and Theses

This thesis investigates the detection and classification of small boats using a passive sonar system. Noise radiated from a small boats consists of broadband noise and harmonically related tones that correspond to parameters in the boats engine and propeller. A novel signal processing method for detection and discrimination of noise radiated from small boats has been developed. There are two main components to the algorithm. The first component detects the presence of small boats by the harmonic tonals radiated from the boat propeller and engine. The second component was designed to extract the a signature from passive sonar data. The …

1, 2-Bis (Phenylsulfonyl)-1h-Indole As An Acceptor Of Organocuprate Nucleophiles, David C. Qian, Philip E. Alford, Tara L. S. Kishbaugh, Sean T. Jones, Gordon W. Gribble Jan 2010

1, 2-Bis (Phenylsulfonyl)-1h-Indole As An Acceptor Of Organocuprate Nucleophiles, David C. Qian, Philip E. Alford, Tara L. S. Kishbaugh, Sean T. Jones, Gordon W. Gribble

Dartmouth Scholarship

1,2-Bis(phenylsulfonyl)-1H-indole is a novel example of an electron-deficient indole that undergoes nucleophilic attack at C-3. Though a variety of other organometallic nucleophiles fail to engender nucleophilic substitution, organocuprates produce 3-substituted 2-(phenylsulfonyl)-1H-indoles. These reactions contribute to the growing number of examples of nucleophilic addition to the indole core.

Sticky Points In Modeling Household Energy Consumption, Loren Lutzenhiser, Mithra Moezzi, David Hungerford, Rafael Friedmann Jan 2010

Sticky Points In Modeling Household Energy Consumption, Loren Lutzenhiser, Mithra Moezzi, David Hungerford, Rafael Friedmann

Center for Urban Studies Publications and Reports

A variety of approaches have been proposed to explaining individual household energy consumption, its variation, and its potential reduction. Some focus on technology, some on costs, and some on a combination of behaviors, attitudes, intentions, and norms. All try to make sense of a problem that, from a modeling perspective, involves hundreds of potentially important factors, yet is supported by highly inadequate or at best selective data. While there is value in "doing the best one can" with the resources at hand, building a defensible science requires a cold hard look at the quality of theory, research and data. This …

Governance, Technology, And The Search For Modernity In Kenya, Warigia M. Bowman Jan 2010

Governance, Technology, And The Search For Modernity In Kenya, Warigia M. Bowman

Articles, Chapters in Books and Other Contributions to Scholarly Works

An ICT policy that produces broad access quickly is better than one that does not. Accordingly, success in ICT policymaking can be measured by three empirical measures: speed of passage, scope of implementation, and distribution, as well as one normative measure, process. "Process" represents an important normative dimension of ICT policymaking. Process measures the extent to which the ICT policymaking involves the citizenry, as represented by individuals, civil society groups, local private sector groups, and ideally, urban and rural residents ("wananchi "). Kenya is a case of slow speed of passage, low scope of implementation, low distribution, but high process. …
