Limit States Design Of Deep Foundations, Kevin Christopher Foye, Grace Abou Jaoude, Rodrigo Salgado

JTRP Technical Reports

Load and Resistance Factor Design (LRFD) shows promise as a viable alternative to the present working stress design (WSD) approach to foundation design. The key improvements of LRFD over the traditional Working Stress Design (WSD) are the ability to provide a more consistent level of reliability and the possibility of accounting for load and resistance uncertainties separately. In order for foundation design to be consistent with current structural design practice, the use of the same loads, load factors and load combinations would be required. In this study, we review the load factors presented in various LRFD Codes from the US, …

Methodology For The Development Of A Highway Asset Management System For Indiana, Zongzhi Li, Kumares C. Sinha

JTRP Technical Reports

Groundwater Trends In The Kent-Frankland Sub-Region, Arjen Ryder

Natural resources published reports

The South Coast Regional Initiative Planning Team (SCRIPT) has divided the South Coast region of Western Australia into six sub-regions. Kent-Frankland covers the catchments of the Frankland, Gordon and Kent' Rivers. Approximately two-thirds (450,000 ha) has been cleared for agriculture. This publication describes the groundwater trends, risk of shallow watertables, and technical feasibility of salinity management on agricultural land.

Soil-landscape zones are spatial units based on geology and geomorphology. Since most groundwater processes in WA are controlled by the geologic and regolith properties, these zones can be used for allocating hydrological attributes, such as groundwater characteristics and trends. The hydrological …

The Emergence Of A Middle Class Among Turks In Germany: A Move Toward Cultural Pluralism, Eden Blythe Hegwood

Honors Theses

This thesis examines the recent development of a middle class among the current Turkish community in Gemiany. By following the generations of individuals of Turkish descent from the original guest-workers arriving in Germany in the early 1960s on to the third and fourth generations of German Turks, the process of middle class establishment over time becomes apparent. Paralleling the emergence of Turkish middle class, increased acculturation or cultural assimilation has occurred, which is also described herein in terms of generational accomplishment. Finally, this work seeks to determine the relationship between middle class status and integration among this migrant group in …

The (Non)Taxation Of Risk, David A. Weisbach

Coase-Sandor Institute for Law & Economics Research Paper Series

A long line of literature argues that income taxes do not tax the return to risk bearing. The conclusion, if correct, has important implications for the choice between an income tax and a consumption tax and for the design of income taxes. The literature, however, on its face seems unrealistic because it models only very simplified tax systems, assumes perfect rationality by individuals, and requires the government to take complex positions in securities markets to hold in equilibrium. This paper examines the extent to which these problems affect the conclusions we draw from the literature. It argues that the criticisms …

A Physics-Based Analytical Model Of An Algan/Gan High Electron Mobility Transistor, Jonathan Sippel

Theses

Popular semiconductors currently being used for RF applications include GaAs and InP. The operating frequencies for HEMTs built with these semiconductors covers the range from 800 MHz to 100 GHz. Although high-speed operation is attainable using GaAs or InP, product performance is limited when considering high-power applications, where a high breakdown field and thermal conductivity is needed. Proposed about fifteen years ago as a solution to this problem, GaN has emerged as a viable candidate to challenge, and perhaps overtake, GaAs and InP as the dominant semiconductor in RF products, particularly power amplifiers. This is due to its high breakdown …

They are also being considered for high heat flux applications under microgravity environment in space missions. Research laboratories and industries throughout the world are trying to explore and tap the potential uses of these small diameter channels in various products and applications. Before stepping in to any of the product design phase, fundamental issues related to their performance have to be studied and resolved. This thesis work focuses on resolving some of these fundamental issues related to flow boiling in small diameter channels …

Analytical And Numerical Modeling To Address Signal Integrity Issues In Mixed Signal Applications, Jeffrey D. Mcfiggins

Theses

Signal integrity issues are a major concern in highly integrated and compact mixed signal IC's. This work presents a numerical and analytical method for analyzing and assessing signal integrity issues relating to discontinuities, interconnects, and irregularly shaped power planes through the development of two independent methods. To address the coupling issue the finite difference time domain (FDTD) technique has been used, which is an accurate and robust algorithm capable of analyzing an arbitrary geometry in both the frequency and time domains. The analysis of signal integrity issues is carried out using examples such as transmission lines placed in close proximity, …

Feasibility Analysis Of Correlation Based Prefetching Using Digital Signal Processing, David L. Morse

Theses

As the gap between processor performance and memory performance continues to broaden with time, techniques to hide memory latency such as correlation based prefetching become exceedingly important. When a memory reference issued by the processor misses the level one cache, the request propagates down the memory hierarchy until it finally finds the requested datum. With each layer traversed, the latency grows exponentially. Prefetching is a technique used to hide this latency by attempting to predict which memory references will be requested in the near future, and then load them into cache before they are needed. This work investigates the use …

Evaluation Of The Playstation 2 As A Cluster Computing Node, Christopher R. Nigro

Theses

Cluster computing is currently a popular, cost-effective solution to the increasing computational demands of many applications in scientific computing and image processing. A cluster computer is comprised of several networked computers known as nodes. Since the goal of cluster computing is to provide a cost-effective means to processing computationally demanding applications, nodes that can be obtained at a low price with minimal performance tradeoff are always attractive. Presently, the most common cluster computers are comprised of networks of workstations constructed from commodity components. Recent trends have shown that computers being developed and deployed for purposes other than traditional personal computers …

Concurrent Evolution Of Feature Extractors And Modular Artificial Neural Networks, Victor Hannak

Theses

Artificial Neural Networks (ANNs) are commonly used in both academia and industry as a solution to challenges in the pattern recognition domain. However, there are two problems that must be addressed before an ANN can be successfully applied to a given recognition task: ANN customization and data pre-processing. First, ANNs require customization for each specific application. Although the underlying mathematics of ANNs is well understood, customization based on theoretical analysis is impractical because of the complex interrelationship between ANN behavior and the problem domain. On the other hand, an empirical approach to the task of customization can be successful with …

Data Hiding In Images Based On Fractal Modulation And Diversity Combining, Sarat B. Atluri

Theses

The current work provides a new data-embedding infrastructure based on fractal modulation. The embedding problem is tackled from a communications point of view. The data to be embedded becomes the signal to be transmitted through a watermark channel. The channel could be the image itself or some manipulation of the image. The image self noise and noise due to attacks are the two sources of noise in this paradigm. At the receiver, the image self noise has to be suppressed, while noise due to the attacks may sometimes be predicted and inverted. The concepts of fractal modulation and deterministic self-similar …

Forecasting Hospital Bed Availability Using Computer Simulation And Neural Networks, Matthew J. Daniels

Theses

The success of hospitals in treating patients and staying in business relies on their efficient use of resources. In particular, the utilization of hospital beds is a critical concern, since over-crowding will result in delays or transfers of patients, and under-utilization will result in lost opportunity to treat patients and generate profit. To this end, hospital decision makers must have reliable forecasts of patient demand and bed availability. The objective of this thesis was to create a general method to forecast the availability of hospital beds in the short term, up to 2 days into the future. Specifically, this thesis …

Modeling Periodic Blade Stresses Due To Stator-Rotor Interactions Using Computational Fluid Dynamics, Lisa M. Barrett

Theses

High cycle fatigue (HCF) is a common problem in military turbofan engines, resulting in engine component failure, and billions of dollars a year in repair and maintenance. HCF occurs due to engine component aerodynamic interactions, including vortical and potential field effects. In 1987, the IHPTET program was created by the U.S. Department of Defense. One of the goals of this program was to reduce high cycle fatigue in engine components. A method of reducing the amount of HCF occurring in a turbofan engine is referred to as trailing edge blowing (TEB). TEB reduces the vortical, or wake, components of a …

Enhanced Closed Loop Performance Using Non-Dimensional Analysis, Michael H. Wilson

Theses

This paper investigates the benefits of using non-dimension analysis to develop a control law for a flexible electro-mechanical system. The system that is analyzed consists of a DC motor connected to a load inertia through a set of gears. A state space system model is derived using LaGrange's equation and then non-dimensionalized using a linear transformation. The resulting system model reveals the system character more clearly through the resulting dimensionless parameters. The parameters highlight the interaction between system properties and motor constants and demonstrate the benefits of a concurrent mechatronics design process. Open-loop behavior is analyzed and an optimal value …

Husserl's Phenomenological Reduction Revisited: An Attempt Of A Renewed Account, Sebastian Luft

Philosophy Faculty Research and Publications

This essay attempts a renewed, critical exposition of Husserl’s theory of the phenomenological reduction, incorporating manuscript material that has been published since the defining essays of the first generation of Husserl research. The discussion focuses on points that remain especially crucial, i. e. the concept of the natural attitude, the ways into the reduction, and the question of the “meaning of the reduction”. The reading attempted here leads to two, not necessarily related, focal points: a Cartesian and a Life-world tendency. In following these two paths, Husserl was consistent in pursuing two evident leads in his philosophical enterprise; however, he …

Husserl’S Theory Of The Phenomenological Reduction: Between Life-World And Cartesianism, Sebastian Luft

Philosophy Faculty Research and Publications

This essay attempts a renewed, critical exposition of Husserl's theory of the phenomenological reduction, incorporating manuscript material that has been published since the defining essays of the first generation of Husserl research. The discussion focuses on points that remain especially crucial, i.e., the concept of the natural attitude, the ways into the reduction (and their systematics), and finally the question of the "meaning of the reduction." Indeed, in the reading attempted here, this final question leads to two, not necessarily related, focal points: a Cartesian and a Life-world tendency. It is my claim that in following these two paths, Husserl …
