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

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 …

Dynamical Perception: Modeling Framework, Model And Experiment, Felix Almonte Jan 2006

Dynamical Perception: Modeling Framework, Model And Experiment, Felix Almonte

Electronic Theses and Dissertations 2000 - 2009

Can a distributed anatomical and functional architecture serve as the basis for sufficiently complex perceptual phenomena? In addressing this question, the conceptual notion of dynamical system and its relation to other paradigms is considered including its definition. The principal goal is to develop a dynamical framework on which to ground the theoretical study of perception and other physical phenomena. As an entry point, the perceptual dynamics of auditory streaming are modeled using a neurally inspired dynamical model of auditory processing. Traditional approaches view streaming as a competition of streams, realized within a tonotopically organized neural network. In contrast, streaming can …

Enduring Relationship With The Dead: The Corpse, The Feminine And Popular Culture, Suzanne M. Kelly Jan 2006

Enduring Relationship With The Dead: The Corpse, The Feminine And Popular Culture, Suzanne M. Kelly

Electronic Theses and Dissertations 2000 - 2009

Feminist theory has long criticized the hierarchical and oppositional thinking responsible for creating the basis of what counts as real knowledge. In questioning how and why the experience of enduring relationship with the dead is not imagined as real, this dissertation will draw from this theoretical tradition. This analysis involves a paradigm shift in thinking about the nature of relationship---one that posits these kinds of experiences as something other than either a psychological remedy to our grief or the requisite belief in the survival of the self. Feminist critiques of dualistic thinking become the cornerstone of Chapter One in order …
