An Investigation On Transversely Prestressed Concrete Bridge Decks, J. A. Ramirez, Jhon Paul Smith

JTRP Technical Reports

This study is concerned with the development of design specifications for the use of transverse post-tensioning in concrete bridge decks. The ultimate goal behind this proposal is to improve the durability of concrete bridge superstructures. Experimental results from previous studies are used to validate the analytical models implemented in the development of the design specifications. It is found that the required distribution of transverse post-tensioning is such that different application levels of prestressing are required in regions containing the interior and exterior (or outermost) diaphragms. It is also concluded that the magnitude of such transverse forces is a function of …

Evolution As Learning Yields Hyperbolic Discounting, James Woods

Economics Faculty Publications and Presentations

Learning is modeled as an infection, which jumps from person to person. The rate of infection mimics individual discount rates and induces savings behavior on its own. It is shown that the apparent discount rate, the combination of the agents’ true discount rate and the infection rate, decreases over time and approaches the agents’ true discount rate. This decrease, known as hyperbolic discounting, is consistent with what is observed in psychology studies, while the limiting case, exponential discounting, is consistent with market level observations. This model closes the gap between individual and market level observations of discounting behavior without explicitly …

Toscanini And The Myth Of Textual Fidelity, Linda B. Fairtile

University Libraries Faculty and Staff Publications

Changes in the public perception of performing artists make for fascinating study. There once was a time when the Three Tenors were considered mere mortals. And there was a time when a conductor, Arturo Toscanini, was considered the living embodiment of the composers whose music he performed. Largely through the efforts of the press and the National Broadcasting Company, Toscanini came to be known as the only musician with the integrity and modesty to perform a composition exactly as it was notated in the musical score. Thanks to the existence of recorded performances, as well as the reminiscences of some …

Balancing The 'E' With Learning And Teaching Skills, Áine O'Brien

Theses

Many lecturers today want to move past passive learning to active learning, to find better ways of engaging students in the learning process. Since most groups of individuals have a variety of learning styles, the lecture material needs to be presented in a variety of ways. With the introduction of web-based learning and e-leaming, lecturers can use a variety of teaching methods with their students.

This study will focus on what is required to balance the ‘E’ with the ‘learning’ skills and ‘teaching’ skills. Too often there is more emphasis placed on the ‘E’ aspect with little consideration given to …

Measuring Software Size For Continuous Process Improvement, Claire O'Sullivan

Theses

This thesis looks at how the size of a software product can be measured. It looks at current software sizing methods (LOC and FPA) and shows that they are not sufficient in today’s rapidly changing environment. The COSMIC-FFP method is introduced and an overview of how it works is given. The hypothesis to be tested in this thesis is whether COSMIC-FFP is an accurate, repeatable sizing method that when applied to any type of software project produces a size measure that can be used to predict the effort required to complete the project.

This thesis investigates the use of the …

Thermal Assessment Of Silicon-Based Composite Materials Used In Photovoltaics, Pavlos K. Bataglannis

Theses

Photovoltaics are devices that convert sunlight directly to electricity. It is well established that the conversion efficiency of mono and poly-crystalline silicon-based photovoltaic modules is inversely related to their temperature. Substantial improvements in operational performance can thus be achieved if the thermal energy accumulating in the material can be effectively dissipated.

Accurate modelling of modules would allow possible methods of thermal dissipation to be evaluated, and as a crucial component of the model, the thermal properties of the constituent materials of PV modules needed to be known. Special consideration needed to be given to the interfaces between dissimilar materials and …

Development Of An Automated Thiopurine Methyltransferase (Tpmt) Genotyping Assay, Mary Corcoran

Theses

Thiopurine methyltransferase (TPMT) is a cytosolic enzyme that catalyses the S- methylation of aromatic and sulphydryl compounds known as the thiopurines. These therapeutic agents are used in the treatment of acute lymphoblastic leukemia, autoimmune disorders, inflammatory bowel disease and organ transplant recipients.

Erythrocyte TPMT activity is polymorphic and patients with intermediate or deficient TPMT are at significant risk for excessive toxicity after receiving ‘standard’ doses of thiopurine medications. The activity of TPMT is inherited as an autosomal co-dominant trait. Several mutations in the TPMT gene have been described that correlate with a low activity phenotype. Three mutations G238C, G460A and …

Sip Message Compression Technique For Efficient Multimedia Services In 3g Wireless Communications, Valerie Kenneally

Theses

The direction of the global cellular industry is primarily determined by two standardisation bodies, the 3rd Generation Partnership Project (3GPP) (in Europe and Asia) and 3GPP2 (in North America). Both of these standardisation bodies are currently specifying a core network to deliver IP based multimedia services over 3G wireless networks. One of the fundamental building blocks of this IP based multimedia core network is the use of SIP (Session Initiation Protocol) as the control protocol. The radio resource, that is the available frequency spectrum, in wireless communication systems remains a limiting factor in terms of the bandwidth available to an …

Multiple Model Control With Intelligent Switching To Ensure Robustness To Process Variations., Peter Cunningham

Theses

One of the most popular approaches for dealing with process that undergo large variations with time, of late, is the multiple model approach. This method has considerable intuitive appeal and has received widespread dissemination in academia. Numerous successful simulations have been reported although few real-time results have been published. The principal contribution of this thesis is the application of the multiple model control scheme in real-time.

A number of practical concepts that enable the use of multiple model control in real-time are discussed. Many of these issues arose when the multiple model control scheme was applied to a laboratory scale …

Modern Control Techniques For Induction Machines In High-Performance Adjustable-Speed Drives, Pat Cronin

Theses

Induction Motors (IM’s) are increasingly being considered for and used in high-performance motor drive (HPMD) systems. Their application has only gained acceptance since the 1970’s with the advent of vector control, microprocessors and improvements in power converter technology. D.C. motors were traditionally the preferred choice in HPMD systems. The main reasons for IM acceptance in HPMD systems are ruggedness, durability, low maintenance, cost, and small size by comparison with D.C. motors.

Alternating current asynchronous motors of the IM type are considered to be the universal workhorses of the manufacturing industry. It has been estimated that they are used in seventy …

Three Legal Frameworks For Regulating Genetic Technology, Wilson R. Huhn

Akron Law Faculty Publications

The Genetic Age promises another exponential increase in human knowledge and potential. ... This article describes three frameworks the law uses to regulate genetic technology: (1) Individual Rights and Duties; (2) Scientific Regulation by Administrative Agencies; and (3) Legislative Preemption. ... This framework involves the lowest level of government oversight over genetic technology. ... At present, the FDA and National Institutes of Health (NIH) administer regulatory control of genetic technology as applied to human beings, but the jurisdiction of these agencies is limited. ... Attorney Judith Cregan has recorded a number of "serious problems" with FDA and NIH regulation of …

Stages Of Legal Reasoning: Formalism, Analogy, And Realism, Wilson R. Huhn

Akron Law Faculty Publications

In the late 19th Century, legal reasoning was dominated by formalistic analysis. Judges and lawyers reasoned deductively from base principles. Legal historians have persuasively described how leading judges and scholars fomented a revolution in legal thought in the 20th Century. Starting about 1910, legal realism--or policy analysis-- entered legal reasoning to the point that today it would be unusual to find a judicial opinion or brief that fails to explore the policy implications of an interpretation of the law. This historical shift from formalism to realism suggests that there are stages of legal reasoning.

In this Article, I argue that …
