Video Modeling Via Implicit Motion Representations, Yunfei Zheng

Graduate Theses, Dissertations, and Problem Reports (ETD)

Video modeling refers to the development of analytical representations for explaining the intensity distribution in video signals. Based on the analytical representation, we can develop algorithms for accomplishing particular video-related tasks. Therefore video modeling provides us a foundation to bridge video data and related-tasks. Although there are many video models proposed in the past decades, the rise of new applications calls for more efficient and accurate video modeling approaches.;Most existing video modeling approaches are based on explicit motion representations, where motion information is explicitly expressed by correspondence-based representations (i.e., motion velocity or displacement). Although it is conceptually simple, the limitations …

How acquisition professionals measure and select capability improvements for the nation’s weapon systems is a perpetual challenge, made even more complex with constrained defense budgets. This study identifies a method for determining which upgrades should be purchased (production) for which aircraft in the F- 15C fleet by optimizing a capability proxy measure. Each upgrade’s “necessity” for a given mission area was obtained by conducting a survey of over 250 experienced F-15C pilots. The solution presented in …

Evaluating The Influence Of Airport Governance Structures On Financial Performance, Marcelo Lima

Theses and Dissertations

Medium hub airports in the United States vary in their governance structures. Airports are operated by an airport authority, transportation authority, city, county or state governance. These different types of governance structures establish the guidelines of how an airport will operate. The predicted growth in air travel in the coming years has inauspiciously coincided with expected cuts in federal airport funding programs. Airport profits, operating costs and cost per enplaned passenger were compared among the five governing structures to evaluate financial performances among the airport groups. The comparison was done using a one-way analysis of variance (ANOVA) and Tukey tests. …

Kinematic Demands Of Nucleus Arthroplasty Technology, Elizabeth J. Sander

Theses and Dissertations (ETD)

Recent advancements in biomaterial technologies have fostered growth in alternative surgical procedures to fusion surgery for treatment of early stages of degenerative disc disease. One application of immediate interest is that of nucleus arthroplasty (NA). Novel materials are being developed to better match the nonlinear biomechanical properties of the native tissue. The effects of changing the motion segment unit (MSU) properties via surgery (nucleotomy) or placement of a nucleus arthroplasty material, changes the effort or work required to move the altered spine condition through a prescribed kinematic path relative to the intact spine condition. The closer the loading mechanics of …

Hamas And Israel: Conflicting Strategies Of Group-Based Politics, Sherifa D. Zuhur Dr.

Books, Monographs & Collaborative Studies

Efforts to separate HAMAS from its popular support and network of social and charitable organizations have not been effective in destroying the organization, nor in eradicating the will to resist among a fairly large segment of the Palestinian population. It is important to consider this Islamist movement in the context of a region-wide phenomenon of similar movements with local goals, which can be persuaded to relinquish violence or which could become more violent. Certainly an orientation to HAMAS and its base must be factored into new and more practical and effective approaches to peacemaking in the region. At the same …

Conflict Analysis On Everybody Loves Raymond, Alyssa Fernandez

Mako: NSU Undergraduate Student Journal

Interpersonal conflicts are part of everyday life and can be seen from minor disagreements with friends, families, spouses, and others to major disputes, which may be deciding factors for the future of certain relationships. An interpersonal conflict is a struggle between two people because they have conflicting goals or needs or because of some misunderstanding (Beebe, Beebe, and Redmond, 2005). People experience conflicts or disagreements because their needs, such as the need for power, belonging, and freedom, are not the same; there are not enough resources to meet each individual’s goals; or they become too competitive and the goals are …

The future of microprocessors is unknown. Over the past 40 years, their historical trend has been for adopting smaller and more powerful designs that drive the world that we live in today. The state of the microprocessor business today faces a crossroad, wishing to continue on the historical trend of doubling the number of transistors on a chip every 18 months (Moore’s Law) but also facing the realistic task of needing to power these sophisticated devices. With the low voltages and high currents that are required for these microprocessors to operate, it poses a difficult task for the future designers …

High Speed Wavelength Tuning Of Sgdbr Lasers For Optical Coherence Tomography Applications, Benjamin Maher

Master's Theses

The application of Sample Grated Distributed Bragg Reflector (SGDBR) wavelength tunable lasers for swept-wavelength Optical Coherence Tomography (OCT) is explored. OCT is a method of measuring reflectivity versus distance into samples under test with a focused infrared light source. Swept wavelength OCT requires a laser light source that is capable of sweeping its wavelength quickly over the entire wavelength range of the tunable laser. Fast sweeping of the laser's wavelength enables real-time imaging of a wide surface area of the surface under test. This thesis will show that SGDBR lasers can be designed to meet the fast wavelength ramp speeds …

Cultural Aesthetic Experience: Perceptions Of Learning Developed Through Cultural Immersion, Nicole Renai Harper

This inquiry focused specifically on the narratives of seven expatriates undergoing the process of cultural immersion in Germany, Slovenia and the United States. Using narrative inquiry (Clandinin & Connelly, 2000; He, Phillion & Connelly, 2005), participants were engaged in discussion, observation and interview for the purpose of exploring and analyzing how they make meaning from previous knowledge and their developing encounters with …

An Investigation On Spot-Weld Modeling Complexity For Crash Simulation, Srinivasan Vimalanathan

All Theses

In order to design car body structures which are safe during crash, modern automotive manufacturers perform both full-scale experimental crash tests and computer simulation of vehicle crash events using commercially available Finite Element Analysis (FEA) packages such as ABAQUS or LS-DYNA. Use of crash simulations significantly reduces the number of real time crash experiments needed and reduces the time required for design changes. However, in order to capture accurately crash behavior during high-speed impact, a large amount of detailed FEA modeling features such as number and types of elements, mesh element size, number of components, different types of connectors, material …

Protecting Critical Infrastructure With Games Technology, Adrian Boeing, Martin Masek, Bill Bailey

Australian Information Warfare and Security Conference

It is widely recognised that there is a considerable gap in the protection of the national infrastructure. Trying to identify what is in fact ‘critical’ is proving to be very difficult as threats constantly evolve. An interactive prototyping tool is useful in playing out scenarios and simulating the effect of change, however existing simulators in the critical infrastructure area are typically limited in the visual representation and interactivity. To remedy this we propose the use of games technology. Through its use, critical infrastructure scenarios can be rapidly constructed, tested, and refined. In this paper, we highlight the features of games …

Biogeography-Based Optimization, Daniel J. Simon

Electrical and Computer Engineering Faculty Publications

Biogeography is the study of the geographical distribution of biological organisms. Mathematical equations that govern the distribution of organisms were first discovered and developed during the 1960s. The mindset of the engineer is that we can learn from nature. This motivates the application of biogeography to optimization problems. Just as the mathematics of biological genetics inspired the development of genetic algorithms (GAs), and the mathematics of biological neurons inspired the development of artificial neural networks, this paper considers the mathematics of biogeography as the basis for the development of a new field: biogeography-based optimization (BBO). We discuss natural biogeography and …

Climate Change And Consumption, Michael P. Vandenbergh, Douglas A. Kysar

Vanderbilt Law School Faculty Publications

To achieve the level of greenhouse gas emissions reductions called for by climate change experts, officials and policy analysts may need to develop an unfamiliar category of regulated entity: the consumer. Although industrial, manufacturing, retail, and service sector firms undoubtedly will remain the focus of climate change policy in the near term, individuals and households exert a greenhouse footprint that seems simply too large for policymakers to ignore in the long term. This paper, written as a foreword for the Environmental Law Reporter's symposium issue, "Climate Change and Consumption," emerges from an interdisciplinary conference of the same title held at …
