A Dynamic Hierarchical Web-Based Portal, Matthew James Spaulding

USF Tampa Graduate Theses and Dissertations

A dynamic hierarchical web-based portal was created to house a suite of web-based supply chain management applications. The portal was designed in a hierarchical manner to match the structure of large companies. Administrators of the the portal have the ability to form the portal in such a way to mimic the existing structure of their company. Access rights to the applications in the portal may be granted or denied per division and the users of the portal are placed in these divisions based on their duty in the company. In addition, users are granted roles which dictate their ability to …

Heterogeneous Modeling Of Medical Image Data Using B-Spline Functions, Olya Grove

USF Tampa Graduate Theses and Dissertations

Ongoing developments in the field of medical imaging modalities have pushed the frontiers of modern medicine and biomedical engineering, prompting the need for new applications to improve diagnosis, treatment and prevention of diseases.

Biomedical data visualization and modeling rely predominately on manual processing and utilization of voxel and facet based homogeneous models. Biological structures are naturally heterogeneous and in order to accurately design and biomimic biological structures, properties such as chemical composition, size and shape of biological constituents need to be incorporated in the computational biological models.

Our proposed approach involves generating a density point cloud based on the intensity …

Optimization Of Proximity Judgment, Brian Day

USF Tampa Graduate Theses and Dissertations

As humans, we have evolved to see in three dimensions. Our ancestors developed two eyes that only look forward, which allows the visual area that can perceive depth to be most of the field of view. A variety of sensors have been developed which can determine depth in the environment. They range from producing individual points of depth to the depth of everything in the environment. These sensors have become cheap and can now reliably produce accurate depth. Research is needed to determine how to present the proximity information to the people using the sensors. Touch, sound, and vision have …

An Event-Based Approach To Describing And Understanding Museum Narratives, Paul Mulholland, Annika Wolff, Trevor Collins, Zdenek Zdrahal

Publications

Current museum metadata tends to be focused around the properties of the heritage object such as the artist, style and date of creation. This form of metadata can index a museum’s collection but cannot express the relations between heritage objects and related concepts found in contemporary museum exhibitions. A modern museum exhibition, rather than providing a taxonomic classification of heritage objects, uses them in the construction of curatorial narratives to be interpreted by an audience. In this paper we outline how curatorial narratives can be represented semantically using our Curate Ontology. The Curate Ontology, informed by a detailed analysis of …

Selection And Implementation Of Technologies For The Re-Engineering Of An Existing Software System, Stan William Naspinski

USF Tampa Graduate Theses and Dissertations

A major hurdle for any company to cross is the act of re-engineering software if they wish to stay relevant. With the speed that software and technology advances, it would be ignorant for any product to stagnate. With that comes the inherent difficulties of choosing which of the older technologies to keep (if any) and which newer technologies to employ in the re-engineered solution. Once that is covered, the actual implementation presents its own set of challenges to both the decision makers and developers in the process.

This thesis describes a case study, in particular the efforts put forth to …

Live Video Streaming From Android-Enabled Devices To Web Browsers, Justin M. Bailey

USF Tampa Graduate Theses and Dissertations

The wide-spread adoption of camera-embedded mobile devices along with the ubiquitous connection via WiFi or cellular networks enables people to visually report live events. Current solutions limit the configurability of such services by allowing video streaming only to fixed servers. In addition, the business models of the companies that provide such (free) services insert visual ads in the streamed videos, leading to unnecessary resource consumption.

This thesis proposes an architecture of a real-time video streaming service from an Android mobile device to a server of the user's choice. The real-time video can then be viewed from a web browser. The …

A Novel Correlation Networks Approach For The Identification Of Gene Targets, Kathryn Dempsey Cooper, Stephen Bonasera, Dhundy Raj Bastola, Hesham Ali

Interdisciplinary Informatics Faculty Proceedings & Presentations

Correlation networks are emerging as a powerful tool for modeling temporal mechanisms within the cell. Particularly useful in examining coexpression within microarray data, studies have determined that correlation networks follow a power law degree distribution and thus manifest properties such as the existence of “hub” nodes and semicliques that potentially correspond to critical cellular structures. Difficulty lies in filtering coincidental relationships from causative structures in these large, noise-heavy networks. As such, computational expenses and algorithm availability limit accurate comparison, making it difficult to identify changes between networks. In this vein, we present our work identifying temporal relationships from microarray data …

Grouper: A Packet Classification Algorithm Allowing Time-Space Tradeoffs, Joshua Adam Kuhn

USF Tampa Graduate Theses and Dissertations

This thesis presents an algorithm for classifying packets according to arbitrary (including noncontiguous) bitmask rules. As its principal novelty, the algorithm is parameterized by the amount of memory available and can customize its data structures to optimize classification time without exceeding the given memory bound. The algorithm thus automatically trades time for space efficiency as needed. The two extremes of this time-space tradeoff (linear search through the rules versus a single table that maps every possible packet to its class number) are special cases of the general algorithm we present. Additional features of the algorithm include its simplicity, its open-source …

Making Memory: Techne, Technology, And The Refashioning Of Contemporary Memory, Kimberly Lacey

Wayne State University Dissertations

My dissertation answers two questions: Does the tension between interactive technologies and rhetoric re-shape the nature and relevance of the canon of memory? Do interactive technologies affect the ways we remember and persuade? I argue that my interpretation of techne suggests possibilities for the creation and production of new types of memory in combination with digital media. To interrogate this connection, I suggest three interpretations of the Greek concept, techne: as a process that is inherently productive; as a force that renegotiates contemporary sources of social power; and as a skill that balances expert knowledge with instrumentality. I explore …

Development Of An Expert System To Aid In The Selection Of Sustainability Design Engineering Methods, Pedro Renato Acosta

Open Access Theses & Dissertations

The objective of this thesis is to present the development of an expert system to aid designers in the selection of design methods, in particular for sustainability methods. When practicing engineers need help in their design process, they look for design methods and tools; this is a challenge especially for inexperienced engineers in the sustainability area. Engineers, due to time constrains, will only utilize one or few methods during their professional life. The origin of this situation can be traced to engineering education, where it is typical that an instructor prefers one or few methods in particular, and even when …

The Role Of Contextual Associations In The Selection Of Objects, Noah Patrick Sulman

USF Tampa Graduate Theses and Dissertations

This paper describes a sequence of experiments addressing basic questions about the control of visual attention and the relationship between attention and object recognition. This work reviews compelling findings addressing attentional control on the basis of high-level perceptual properties. In five experiments observers were presented with a rapid sequence of object photographs and instructed to either detect or selectively encode a verbally cued object category. When these object categories (e.g. "baseball") were preceded by contextual images associated with a given object category (e.g. "baseball diamond"), observers were less likely to accurately report information about the target item. This effect obtained …

Modularizing Crosscutting Concerns In Software, Nalin Saigal

USF Tampa Graduate Theses and Dissertations

Code modularization provides benefits throughout the software life cycle; however, the presence of crosscutting concerns (CCCs) in software hinders its complete modularization. Traditional modularization techniques work well under the assumption that code being modularized is functionally orthogonal to the rest of the code; as a result, software engineers try to separate code segments that are orthogonal in their functionality into distinct modules. However, in practice, software does not decompose neatly into modules with distinct, orthogonal functionality. In this thesis, we investigate the modularization of CCCs in software using two different techniques.

Firstly, we discuss IVCon, a GUI-based tool that provides …

Robotic Hand Evaluation Based On Task Specific Kinematic Requirements, Carlos Rafael Neninger

USF Tampa Graduate Theses and Dissertations

With the rise autonomous and robotic systems in field applications, the need for dexterous, highly adaptable end effectors has become a major research topic. Control mechanisms of robotics hands with a high number independent actuators is recognized as a complex, high dimensional problem, with exponentially complex algorithms. However, recent studies have shown that human hand motion possesses very high joint correlation which translates into a set of predefined postures, or synergies. The hand produces a motion using a complementing contribution of multiple joints, called synergies. The similarities place variables onto a common dimensional space, effectively reducing the number of independent …

An Analysis Of Remote Biometric Authentication With Windows, Brandy Marie Eyers

USF Tampa Graduate Theses and Dissertations

One thing that everyone seems to be worried about when it comes to his or her computer is security. If your computer is not secure then private information could be stolen. Many people now use passwords to protect themselves though they are discovering that using multi-factor authentication is much more secure. It allows you to use multiple different proofs of who you are. Biometrics is one of the ways to prove identity. Using it, you could log into a system with just a fingerprint, which is something that is very difficult to steal. We present a suite of software tools …

Combining Natural Language Processing And Statistical Text Mining: A Study Of Specialized Versus Common Languages, Jay Jarman

USF Tampa Graduate Theses and Dissertations

This dissertation focuses on developing and evaluating hybrid approaches for analyzing free-form text in the medical domain. This research draws on natural language processing (NLP) techniques that are used to parse and extract concepts based on a controlled vocabulary. Once important concepts are extracted, additional machine learning algorithms, such as association rule mining and decision tree induction, are used to discover classification rules for specific targets. This multi-stage pipeline approach is contrasted with traditional statistical text mining (STM) methods based on term counts and term-by-document frequencies. The aim is to create effective text analytic processes by adapting and combining individual …

Usf's Coverage Of Women's Athletics: A Census Of The Usf Athletics Home Web Page, Laura Ann Lebeau

USF Tampa Graduate Theses and Dissertations

This study examines the coverage of women’s athletics at USF provided through photographic representations on the university’s Athletics Internet home web page during the 2009–2010 academic year. Findings from this census of five areas that comprise the USF Athletics Internet home web page revealed that, consistent with recent research on coverage of female athletes and women’s athletics on university web pages, women, compared to men, were underrepresented in the majority of the five areas of the home page analyzed. The difference in the number of overall total photographs of women and men was not that large—48% and 52%, respectively, not …

Automated Quantification Of Biological Microstructures Using Unbiased Stereology, Om Pavithra Bonam

USF Tampa Graduate Theses and Dissertations

Research in many fields of life and biomedical sciences depends on the microscopic image analysis of biological images. Quantitative analysis of these images is often time-consuming, tedious, and may be prone to subjective bias from the observer and inter /intra observer variations. Systems for automatic analysis developed in the past decade determine various parameters associated with biological tissue, such as the number of cells, object volume and length of fibers to avoid problems with manual collection of microscopic data. Specifically, automatic analysis of biological microstructures using unbiased stereology, a set of approaches designed to avoid all known sources of systematic …

Using A Focus Measure To Automate The Location Of Biological Tissue Surfaces In Brightfield Microscopy, Daniel Toby Elozory

USF Tampa Graduate Theses and Dissertations

The study of microstructures in brightfield microscopy using unbiased stereology plays a large and growing role in bioscience research. Stereology enables objective quantitative analysis of biological structures within a tissue sample. A first step in the stereology process is to calculate the thickness of a tissue sample by locating the top and bottom surfaces of the sample. The aim of this project is to fully automate this location process by using the relative optical focus measure as an indicator of tissue surface boundary.

The current method for identification of focus bounding planes requires a trained user to manually select the …

New Media Photographic Representations Of Women`S Collegiate Volleyball: Game Faces, Action Shots, And Equipment, Alicia Pack

USF Tampa Graduate Theses and Dissertations

Researchers consistently find that mainstream media often represent women athletes in stereotypical ways including trivialization, sexualization, infantilization, passivity, and utilization of camera down-angles. However, research on new media's visual representation of women athletes is still in its infancy. This study adds to the growing literature on new media's representation of women athletes and concurs with previous findings suggesting that new media might be an outlet that can counter old media gender stereotypes. This thesis used mixed methods of qualitative content analysis and photovoice in order to better understand how Big East volleyball players are represented in photographs on websites: Instances …

Realizing Virtuality: Tracing The Contours Of Digital Culture, Nicholas Andrew Riggs

USF Tampa Graduate Theses and Dissertations

People connect digitally through social media, fusing their relationships with meaning in a non-space of relational potential--a translucent and fluctuating enclave where the self becomes elastic. This thesis explores how I have formed bonds in virtual space through ritual interaction. Looking at the ways I learned to use technology through the progression of a close personal relationship, I suggest that social media use is a performance of identity--a virtuality that exposes how people negotiate the digital enclosure of contemporary society. My story is one of digital nativity and reclaiming love through virtual performance. I show how these performances have had …

Architecture And Compiler Support For Leakage Reduction Using Power Gating In Microprocessors, Soumyaroop Roy

USF Tampa Graduate Theses and Dissertations

Power gating is a technique commonly used for runtime leakage reduction in digital CMOS circuits. In microprocessors, power gating can be implemented by using sleep transistors to selectively deactivate circuit modules when they are idle during program execution. In this dissertation, a framework for power gating arithmetic functional units in embedded microprocessors with architecture and compiler support is proposed. During compile time, program regions are identified where one or more functional units are idle and sleep instructions are inserted into the code so that those units can be put to sleep during program execution. Subsequently, when their need is detected …

Composing Music In Constrained Search Environments, Jeffrey Keene

Electronic Theses and Dissertations

Composing music with computers in constrained search environments adds complexities and problems not present in the traditional problem domain of generative music. The traditional and well researched mechanisms of Markov chains, genetic algorithms and data driven rule based systems do not directly map to a problem domain in which pitch choice and rhythm choice are likely to be highly limited.

We therefore explore several possible solutions to generating rhythms in extremely constrained environments with the goal of generating music that adheres to user specified constraints and is aesthetically pleasing.
