Artistic (Mis)Representation And Commodity Culture In The Picture Of Dorian Gray And The House Of Mirth, Evan Taylor Jan 2015

Artistic (Mis)Representation And Commodity Culture In The Picture Of Dorian Gray And The House Of Mirth, Evan Taylor

Graduate Theses and Dissertations

"Artistic (Mis)representation and Commodity Culture in The Picture of Dorian Gray and The House of Mirth" attempts to establish a trans-Atlantic connection between authors Oscar Wilde and Edith Wharton by considering the manner in which each author's respective protagonist relates to art, commodities, and the society in which he or she lives. By reading Dorian Gray and Lily Bart through the lens of Jean Baudrillard's Simulacra and Simulation (1981), the companion chapters show the extent to which each character's reality is complicated by his or her illusory relationship with both fine arts and social artistry. The ...

Meta-Analysis Of Single-Case Data: A Monte Carlo Investigation Of A Three Level Model, Corina M. Owens

Graduate Theses and Dissertations

Numerous ways to meta-analyze single-case data have been proposed in the literature, however, consensus on the most appropriate method has not been reached. One method that has been proposed involves multilevel modeling. This study used Monte Carlo methods to examine the appropriateness of Van den Noortgate and Onghena's (2008) raw data multilevel modeling approach to the meta-analysis of single-case data. Specifically, the study examined the fixed effects (i.e., the overall average baseline level and the overall average treatment effect) and the variance components (e.g., the between person within study variance in the average baseline level, the between ...


Asymmetric Passive Dynamic Walker Used To Examine Gait Rehabilitation Methods, John Sushko Jan 2011

Asymmetric Passive Dynamic Walker Used To Examine Gait Rehabilitation Methods, John Sushko

Graduate Theses and Dissertations

Testing gait rehabilitation devices on humans can be a difficult task, due to the effects of the neurological controls of the human body. This thesis advances the use of a passive dynamic walker (PDW) tuned to have asymmetric gait patterns similar to those with

physical impairments to test rehabilitation devices. A passive dynamic walker is a multipendulum system that has a stable gait pattern when walking down a slope without any energy inputs except the forces due to gravity. A PDW model is better suited for testing

rehabilitation devices because it has been shown to resemble human gait and separates ...

A Monte Carlo Approach For Exploring The Generalizability Of Performance Standards, James Thomas Coraggio Jun 2008

A Monte Carlo Approach For Exploring The Generalizability Of Performance Standards, James Thomas Coraggio

Graduate Theses and Dissertations

While each phase of the test development process is crucial to the validity of the examination, one phase tends to stand out among the others: the standard setting process. The standard setting process is a time-consuming and expensive endeavor. While it has received the most attention in the literature among any of the technical issues related to criterion-referenced measurement, little research attention has been given to generalizing the resulting performance standards. This procedure has the potential to improve the standard setting process by limiting the number of items rated and the number of individual rater decisions. The ability to generalize ...


Modeling Crash Severity And Speed Profile At Roadway Work Zones, Zhenyu Wang Jun 2008

Modeling Crash Severity And Speed Profile At Roadway Work Zones, Zhenyu Wang

Graduate Theses and Dissertations

Work zone tends to cause hazardous conditions for drivers and construction workers since work zones generate conflicts between construction activities and the traffic, therefore aggravate the existing traffic conditions and result in severe traffic safety and operational problems. To address the influence of various factors on the crash severity is beneficial to understand the characteristics of work zone crashes. The understanding can be used to select proper countermeasures for reducing the crash severity at work zones and improving work zone safety. In this dissertation, crash severity models were developed to explore the factor impacts on crash severity for two work ...


Modeling Upper Body Kinematics While Using A Transradial Prosthesis, Derek J. Lura Jun 2008

Modeling Upper Body Kinematics While Using A Transradial Prosthesis, Derek J. Lura

Graduate Theses and Dissertations

The prostheses used by the majority of persons with upper limb amputations today offer a limited range of motion. Relative to anatomical joints transradial (below the elbow) prosthesis users lose at least two of the three degrees of freedom provided by the wrist and forearm. Some myoeletric prostheses currently allow for forearm pronation and supination (rotation about an axis parallel to the forearm) and the operation of a powered prosthetic hand. Body-powered prostheses, incorporating hooks and other cable driven terminal devices, have even fewer active degrees of freedom. In order to perform activities of daily living, an amputee must use ...


Gate Level Dynamic Energy Estimation In Asynchronous Circuits Using Petri Nets, Ryan Mabry Jun 2007

Gate Level Dynamic Energy Estimation In Asynchronous Circuits Using Petri Nets, Ryan Mabry

Graduate Theses and Dissertations

This thesis introduces a new methodology for energy estimation in asynchronous circuits. Unlike existing probabilistic methods, this is the first simulative work for energy estimation in all types of asynchronous circuits.

The new simulative methodology is based on Petri net modeling. A real delay model is incorporated to capture both gate delays and interconnect delays. The switching activity at each gate is captured to measure the average dynamic energy consumed per request/acknowledge handshaking pair. The new type of Petri net is called Hierarchical Colored Asynchronous Hardware Petri net (HCAHPN). The HCAHPN is able to capture the temporal and spatial ...

Multi-Criteria Decision Making In Outpatient Scheduling, Jana Iezzi Jun 2006

Multi-Criteria Decision Making In Outpatient Scheduling, Jana Iezzi

Graduate Theses and Dissertations

Hospital ambulatory patients are seen in outpatient departments (OPDs) located in the hospital. 83.3 million visits were made to these departments in 2002. Many sources of patient waiting time exist including: poor coordination of information, inefficient scheduling, inaccurate time estimation and others. Well-designed and executed patient scheduling has the potential to remedy some of these problems. To properly schedule patients, variability in demand must be addressed. Patients may cancel appointments, arrive late and arrive without appointments. We address this problem based on a Multi-attribute Decision Making (MADM) approach. Decision models are developed using the Simple Additive Weighting (SAW) method ...

Opportunistic Maintenance Policy Of A Multi-Unit System Under Transient State, Sulabh Jain Jun 2005

Opportunistic Maintenance Policy Of A Multi-Unit System Under Transient State, Sulabh Jain

Graduate Theses and Dissertations

Most modern systems are equipped with very complex, expensive, and high technology components whose maintenance costs have become an increasingly large portion of the total operating cost of these systems. Thus, the efficacy of the maintenance policy for these and related systems has become a major concern to both manufacturing and design engineers. Different kinds of maintenance strategies have been proposed to solve the problem. While some of these have proven effective, there is yet no definitive approach that has been found that support the maintainability requirements of transient systems or systems that exhibit transient behavior. Transient behavior is the ...

Performance Evaluation Of Multi-Product Kanban-Like Control Systems, Sachin S. Deokar

Graduate Theses and Dissertations

Over the years, much attention has been given to the analysis of the pull type ordering system to reduce in-process inventory and to improve product quality. Kanban Control Systems are widely used to control the release of parts in multi-stage manufacturing systems operating under a pull mechanism. Considerable research has been done to study the individual manufacturing systems for multi stage and single product. However, not much research has been done to compare different pull control policies for multi product manufacturing systems. Most of the research done in multi-product system assumes that a kanban card is dedicated to a part ...


Modeling Demand Uncertainty And Processing Time Variability For Multi-Product Chemical Batch Process, Rishi Darira Jun 2004

Modeling Demand Uncertainty And Processing Time Variability For Multi-Product Chemical Batch Process, Rishi Darira

Graduate Theses and Dissertations

Most of the literature on scheduling of multi-product batch process does not consider the uncertainties in demand and variability in processing times. We develop a simulation based variable production schedule model for a multi-product batch facility assuming zero wait transfer policy and single product campaign. The model incorporates the demand uncertainties and processing time variability. The impact of demand uncertainties is evaluated in terms of total annual cost, which comprises of the backorder and inventory costs per year. The effect of variability in processing time is measured by the annual production time. We also develop a constant production schedule model ...


Graphical Probabilistic Switching Model: Inference And Characterization For Power Dissipation In Vlsi Circuits, Shiva Shankar Ramani Jun 2004

Graphical Probabilistic Switching Model: Inference And Characterization For Power Dissipation In Vlsi Circuits, Shiva Shankar Ramani

Graduate Theses and Dissertations

Power dissipation in a VLSI circuit poses a serious challenge in present and future VLSI design. A switching model for the data dependent behavior of the transistors is essential to model dynamic, load-dependent active power and also leakage power in active mode - the two components of power in a VLSI circuit. A probabilistic Bayesian Network based switching model can explicitly model all spatio-temporal dependency relationships in a combinational circuit, resulting in zero-error estimates. However, the space-time requirements of exact estimation schemes, based on this model, increase with circuit complexity [5, 24]. This work explores a non-simulative, importance sampling based, probabilistic ...


Estimation Of Switching Activity In Sequential Circuits Using Dynamic Bayesian Networks, Karthikeyan Lingasubramanian Jun 2004

Estimation Of Switching Activity In Sequential Circuits Using Dynamic Bayesian Networks, Karthikeyan Lingasubramanian

Graduate Theses and Dissertations

This thesis presents a novel, non-simulative, probabilistic model for switching activity in sequential circuits, capturing both spatio-temporal correlations at internal nodes and higher order temporal correlations due to feedback. Switching activity, one of the key components in dynamic power dissipation, is dependent on input streams and exhibits spatio-temporal correlation amongst the signals. One can handle dependency modeling of switching activity in a combinational circuit by Bayesian Networks [2] that encapsulates the underlying joint probability distribution function exactly. We present the underlying switching model of a sequential circuit as the time coupled logic induced directed acyclic graph (TC-LiDAG), that can be ...

Development Of Assessment Tasks To Measure The Driving Capabilities Of Persons With Disabilities, Ashwin Upadhyay

Graduate Theses and Dissertations

The need to lead an independent and fuller life is as much a right of a person with physical disability as any other human being. Driving capabilities of a person with a disability have been assessed and evaluated using qualitative techniques. However, certain inadequacies that arise using qualitative measures can be avoided if the assessment is based on quantitative techniques. The above requirement necessitates the need to devise a method and a system which is focused on the right development of the techniques used in assessing and measuring different capabilities (such as range of motion and force input) of the ...


Real Delay Graphical Probabilistic Switching Model For Vlsi Circuits, Vivekanandan Srinivasan Jun 2004

Real Delay Graphical Probabilistic Switching Model For Vlsi Circuits, Vivekanandan Srinivasan

Graduate Theses and Dissertations

Power optimization is a crucial issue at all levels of abstractions in VLSI Design. Power estimation has to be performed repeatedly to explore the design space throughout the design process at all levels. Dynamic Power Dissipation due to Switching Activity has been one of the major concerns in Power Estimation. While many Simulation and Statistical Simulation based methods exist to estimate Switching Activity, these methods are input pattern sensitive, hence would require a large input vector set to accurately estimate Power. Probabilistic estimation of switching activity under Zero-Delay conditions, seriously undermines the accuracy of the estimation process, since it fails ...
