Data Acquisition For Modeling And Visualization Of Vascular Tree, William Lafayette Mondy
Data Acquisition For Modeling And Visualization Of Vascular Tree, William Lafayette Mondy
USF Tampa Graduate Theses and Dissertations
Data can be acquired from tissue's vascular structure and used for modeling and visualization. To acquire data from a vascular tree, we make its structure available for the gathering of data by separating it from the structures of surrounding tissues, which includes the capillary structure. The capillary structure contains important information, but, because of its size, is the most difficult to acquire data from. In this work, we look at methods for contrasting the vascular structure from surrounding tissues, and focus on the use of corrosion casting for this procedure. We collected image data using micro-computer tomography (micro-CT) and converted …
Devised Architecture: Revitalizing The Mundane, Jason Novisk
Devised Architecture: Revitalizing The Mundane, Jason Novisk
USF Tampa Graduate Theses and Dissertations
In today's society, we view new as good, a universal standpoint that has become so commonly accepted as true, that to question it would be absurd. While many new items are an upgrade over their predecessor, it is important to understand that used items still retain a high amount of value and efficacy. Our landscape is filled with the mundane, industrial elements that surround us, yet due to our familiarity with them they are pushed to the background of our consciousness. However their commonplace should not mask their true potential value. By using what is already there before us, we …

Hierarchical Complexity In Metal-Organic Materials: From Layers To Polyhedra To Supermolecular Building Blocks, John Jackson Perry
Hierarchical Complexity In Metal-Organic Materials: From Layers To Polyhedra To Supermolecular Building Blocks, John Jackson Perry
USF Tampa Graduate Theses and Dissertations
The design and synthesis of novel functional materials with fine-tunable physical and chemical properties has been an aspiration of materials scientists since at least Feynman's famous speech "There's Plenty of Room at the Bottom" which has fittingly been credited with ushering in the nanotechnology era. Crystal engineering, as the solid-state manifestation of supramolecular chemistry, is well positioned to make substantial contributions to this worthwhile endeavor. Within the realm of crystal engineering resides the subdiscipline of metal-organic materials (MOMs) which pertains most simplistically to the coordination bond and includes such objects as coordination polymers, metal-organic frameworks (MOFs), and discrete architectures, each …

Biotopia: An Interdisciplinary Connection Between Ecology, Suburbia, And The City, Jessica Phillips
USF Tampa Graduate Theses and Dissertations
In an era when cities and towns are changing rapidly, public spaces are the key to reviving civic engagement. By re-introducing these public realms as ecological environments, we can re-structure the organic growth of civic tissue, re-define the city street into a park environment, and reveal the ecological landmarks that once beautified the landscape. These ecological landmarks will be used as corridors, nodes of circulation and storm water management to not only creates a regenerative landscape but to create a connection between ecology, suburbia and the city. The public realm in America has two roles: it is the dwelling place …

The Mashup As Resistance? A Critique Of Marxist Framing In The Digital Age, Adam Rugg
The Mashup As Resistance? A Critique Of Marxist Framing In The Digital Age, Adam Rugg
USF Tampa Graduate Theses and Dissertations
This thesis critiques contemporary scholarly approaches to the modern musical mashup that rely on outdated and over-generalized Marxist frameworks. These frameworks stem from an Adornian view of the culture industries that places consumers and producers in distinct and opposing roles. The mashup is therefore seen as little more than a subversive weapon for a resistant consumer class in its fight against the hegemonic structure of the mass media. A case study of the prominent mashup artist Girl Talk is presented to illustrate how the mashup can actually function as a celebratory form and how modern technological advances have destabilized traditional …

Cultural Response To Totalitarianism In Select Movies Produced In Czechoslovakia, Hungary And Poland Between 1956 And 1989, Kazimierz Robak
USF Tampa Graduate Theses and Dissertations
This study examines resistance against totalitarian propaganda in select movies produced in regions subjected to Soviet-imposed totalitarian system. From 1939 to the collapse of the Soviet Union in 1991, Central-Eastern Europe has experienced two of the most devastating and genocidal political systems in the history of the humankind. Nazism was destroyed with the end of WWII, and met widespread condemnation. Sovietism, commonly known as Communism, survived WWII and the Soviet totalitarian empire rose to the position of the world's second superpower. Effective and organized Soviet propaganda generated a new convincing image of Sovietism as a harmless, friendly and progressive system. …

Specifically, we use the strain pattern extracted from non-rigid facial motion as a simplified and adequate way to characterize the underlying material properties of facial soft tissues. Such an approach has several unique features. Strain pattern instead of the image …
A Cavity-Backed Coplanar Waveguide Slot Antenna Array, James W. Mcknight
A Cavity-Backed Coplanar Waveguide Slot Antenna Array, James W. Mcknight
USF Tampa Graduate Theses and Dissertations
In this thesis, a cavity-backed slot antenna array is designed for relatively wide instantaneous bandwidth, high gain and low sidelobes. The array consists of four, rectangular, slot elements, arranged side-by-side in a linear array and developed around 5GHz. Two feed points, at opposing sides of the printed array, each excite two of the slot elements through a series feed. This bidirectional feed presents symmetry to the design and prevents the tendency of beam-drift versus frequency as is common with many series-fed arrays. While being fed in-phase, the array will maintain boresight at broadside over the entire operating bandwidth. Also, the …

Identity Negotiation: The Perspective Of Asian Indian Women, Pangri Mehta
Identity Negotiation: The Perspective Of Asian Indian Women, Pangri Mehta
USF Tampa Graduate Theses and Dissertations
Traditional Indian cultural narratives are pervasive and serve to typify personal identity and experience. These cultural narratives portray Indian women as a wife and mother, nurturing, obedient, forbearing, soft-spoken, and the primary transmitters of the ethnic culture. American culture, on the other hand, encourages independence, individualism and a more elastic view towards gender. As assimilation theory suggests, Asian Indians in the United States are likely to assimilate at least some degree into American society. Accordingly, these narratives make up the cultural identity of Indian women in the United States. The contrasting cultural narratives shape the identities of Indian women residing …

Visualizing Sound: A Musical Composition Of Aural Architecture, James Pendley
Visualizing Sound: A Musical Composition Of Aural Architecture, James Pendley
USF Tampa Graduate Theses and Dissertations
We depend on our collective senses in order to rationalize and negotiate space. Unfortunately, sound and acoustics has become a secondary concern to that of the visual perception in architecture. The initial design intent for many modern performance spaces and music education space, for about the past one-hundred years, has not been driven by sound or acoustics, as a consequence the visual perception has become the major infl uence. Prior to modern acoustical applications, performance spaces have been designed for the essence of sound and the form and function had no divisible lines, but with amplifi cation of sound and …

The following project will consist in the study and examination of the concepts and theories that lie in the domain of political theory. The enquiry into the dimensions and complexities of the socio-political organization and the political substance of individual human agents will be conducted with the intellectual assistance of the postmodernist turn of thought. I will interrogate and develop a specifically Foucauldian reading of international politics and the emerging global world order as well as situate Foucault's insights and theorizing in a cosmopolitan framework, which calls for a progressive re-conceptualization of the dimensions of power and the modalities of …
School Work Environment: Transition From Education To Practice, Shane Ross
School Work Environment: Transition From Education To Practice, Shane Ross
USF Tampa Graduate Theses and Dissertations
Learning how to learn as opposed to obtaining the experience to practice any field of professionalism creates a great disconnect between education and careers. Many educational programs do not have the curriculum or a building to transition students into a work atmosphere. When the design of a building and its program creates an environment that bridges the gap between school and work, the psychology and standard of an average graduate greatly increases. Students learn from being taught and personal experience. There are programs that require an internship or similar practice as a mandatory factor of the degree. Apprenticeships connect the …
