Regeneration Of Nature: An Alternative To Ecological Restoration, Tobin Hindle Jan 2006

Regeneration Of Nature: An Alternative To Ecological Restoration, Tobin Hindle

Electronic Theses and Dissertations 2000 - 2009

The Regeneration of Nature: an alternative to ecological restoration is an exploration of the human response to alterations society has imposed on natural ecosystems. Ecological restoration is the dominant response to these degraded systems that has emerged within Western, empirical thought. Restoration as it is characteristically practiced in the United States attempts to reverse human impact by returning an ecosystem to an earlier state of existence; its so called pre-disturbance condition. However, I argue that ecological restoration does not adequately address degraded ecosystems dominating today's landscape primarily because it excludes humans as an integrated part of ecosystems and it ignores …

Role Of Chemical And Visual Cues By Two Sargassum Shrimps In Locating And Selecting Habitats, Corrine F. Jobe

Electronic Theses and Dissertations 2000 - 2009

The Sargassum community is comprised of a unique and diverse assemblage of organisms. Habitat detection by two of the most common invertebrates, Latreutes fucorum and Leander tenuicornis , was investigated. Results of this study do not support that either L. fucorum or L. tenuicornis respond to chemical cues released by the Sargassum habitat in the absence of other information. Habitat selection of both shrimp species was examined as well. Both L. fucorum and L. tenuicornis selected live Sargassum over artificial Sargassum . Moreover, L. fucorum selected Sargassum natans over Sargassum fluitans when only visual cues were available, whereas large-sized L. …

The signature whistles of related Atlantic spotted dolphins ( Stenella frontalis) in the Bahamas were evaluated for similarity. Judges compared the contour patterns of signature whistles pair-wise between 19 dolphins. Whistle parameters between the signature whistles of individuals were statistically compared. There were no significant differences between the signature whistles of male and female calves when the similarity of their whistles was compared to their mothers. However, there was a tendency with female calves more likely to produce signature whistles similar to their mothers' whistles. Three out of five female calves produced signature whistles that were "very similar" or "similar" …


Stepparents And Genetic Parents Use Different Methods To Murder Their Children, Mary Ann Grady Jan 2006

Stepparents And Genetic Parents Use Different Methods To Murder Their Children, Mary Ann Grady

Electronic Theses and Dissertations 2000 - 2009

Stepparents commit filicide more often than do genetic parents. In 1994, using Canadian and British national databases, Daly and Wilson provided evidence that there are motivational differences that may affect the methods by which stepparents and genetic parents kill their children, and that stepfathers were more likely than genetic fathers to commit filicide by methods of beating and bludgeoning, revealing greater resentment and bitterness toward their charges. Genetic fathers were more likely to kill their children by asphyxiation or shooting, perhaps to ensure a less painful and quicker death. In 2004, Weekes-Shackelford and Shackelford, using a United States national database, …

Software Decomposition For Multicore Architectures, Ankit. Jain Jan 2006

Software Decomposition For Multicore Architectures, Ankit. Jain

Electronic Theses and Dissertations 2000 - 2009

Current multicore processors attempt to optimize consumer experience via task partitioning and concurrent execution of these (sub)tasks on the cores. Conversion of sequential code to parallel and concurrent code is neither easy, nor feasible with current methodologies. We have developed a mapping process that synergistically uses top-down and bottom-up methodologies. This process is amenable to automation. We use bottom-up analysis to determine decomposability and estimate computation and communication metrics. The outcome is a set of proposals for software decomposition. We then build abstract concurrent models that map these decomposed (abstract) software modules onto candidate multicore architectures; this resolves concurrency issues. …

System Level Modeling And Simulation With Mldesigner, Fabiano Kovalski Jan 2006

System Level Modeling And Simulation With Mldesigner, Fabiano Kovalski

Electronic Theses and Dissertations 2000 - 2009

System modeling has the potential to enhance system design productivity by providing a platform for system performance evaluations. This model must be designed at an abstract level, hiding system details. However, it must represent any subsystem or its components at any level of specification details. In order to model such a system, we will need to combine various models-of-computation (MOC). MOC provide a framework to model various algorithms and activities, while accounting for and exploiting concurrency and synchronization aspects. Along with supporting various MOC, a modeling environment should also support a well developed library. In this thesis, we have explored …

Ubiquitous Entropy And Heat Death In Philip K. Dick And Pamela Zoline, Krista. Kasdorf Jan 2006

Ubiquitous Entropy And Heat Death In Philip K. Dick And Pamela Zoline, Krista. Kasdorf

Electronic Theses and Dissertations 2000 - 2009

My scientifically informed readings of Philip K. Dick's Ubik (1969) and Pamela Zoline's "The Heat Death of the Universe" (1967) consider entropy's multifarious meanings from both thermodynamics and information theory. Additionally, rather than relying upon overarching assumptions about the texts' cultural moment, I explore each fiction's presentation of entropy as negative or positive. For Dick, the loss of female mothering accelerates the heat death of late-capitalistic society, with entropy a negative, destructive force. Zoline, however, recognizes the injurious ramifications of entrapping women within the gender role of self-sacrificing wife/mother; her protagonist purposefully accelerates entropy production to destroy such a closed …

Vibration Tailoring Of Inhomogeneous Beams And Circular Plates, Demetris. Pentaras Jan 2006

Vibration Tailoring Of Inhomogeneous Beams And Circular Plates, Demetris. Pentaras

Electronic Theses and Dissertations 2000 - 2009

The vibrational behavior of inhomogeneous beams and circular plates is studied, utilizing the semi-inverse method developed by I. Elishakoff and extensively discussed in his recent monograph (2005). The main thread of his methodology is that the knowledge of the mode shape is postulated. The candidate mode shapes can be adopted from relevant static, dynamic or buckling problems. In this study, the exact mode shapes are sought as polynomial functions, in the context of vibration tailoring, i.e. designing the structure that possesses the pre-specified value. Apparently for the first time in the literature, several closed-form solutions for vibration tailoring have been …


Development Of An Intelligent Fuzzy Obstacle Avoidance System Using Sonar Modeling And Simulation, Philip A. Bouxsein Jan 2006

Development Of An Intelligent Fuzzy Obstacle Avoidance System Using Sonar Modeling And Simulation, Philip A. Bouxsein

Electronic Theses and Dissertations 2000 - 2009

Response time to a threat or incident for coastline security is an area needing improvement. Currently, the U.S. Coast Guard is tasked with monitoring and responding to threats in coastal and port environments using boats or planes, and SCUBA divers. This can significantly hinder the response time to an incident. A solution to this problem is to use autonomous underwater vehicles (AUVs) to continuously monitor a port. The AUV must be able to navigate the environment without colliding into objects for it to operate effectively. Therefore, an obstacle avoidance system (OAS) is essential to the activity of the AUV. This …
