Real-Time Detection Of Grip Length Deviation For Fastening Operations: A Mahalanobis-Taguchi System (Mts) Based Approach, Deepak Mohan

Masters Theses

"Hand-held fastening tools are extensively used in manufacturing, especially in aerospace industry. Typically, the process is monitored by the operator and joints are visually inspected after the process is completed. When complex products, such as an aircraft, are considered, fastening process and its inspection can be very time consuming. In addition, no inspection data is typically collected during the process unless a major problem is encountered. Real-time monitoring and verification of the fastening process of joint quality are two important advancements to reduce the manufacturing lead time while ensuring safety and quality"--Abstract, page iv.

Fast Sphere Decoder For Mimo Systems, Praveen G. Krishnan

Masters Theses

"This work focuses on variants of the conventional sphere decoding technique for Multi Input Multi Output (MIMO) systems. Space Time Block Codes (STBC) have emerged as a popular way of transmitting data over multiple antennas achieving the right balance between diversity and spatial multiplexing. The Maximum Likelihood (ML) technique is a conventional way of decoding the transmitted information from the received data, but at the cost of increased complexity. The sphere decoder algorithm is a sub-optimal decoding technique that is computationally efficient achieving a ;symbol error rate that is dependent on the initial radius of the sphere. In this thesis, …

Characterization Of Noise On Pdn And Electromagnetic Shielding, Sandeep K. R. Chandra

Masters Theses

"Modern FPGA and microprocessor have complex logic inside them, which draw current from the Power Distribution Network (PDN). This current drawn from the PDN creates disturbance on the PDN, which then propagates to other IC in different places on the Printed Circuit Board (PCB), and appears as a noise voltage. Ability to predict noise voltage at any point on the PCB gives a greater ability to carefully design the board and the PDN. In order to accurately predict the noise, it is important to accurately predict the current drawn and the transfer impedance from the source to the victim point. …

Domain And Forum: Public Space, Public Freedom, Rebecca Tushnet

Georgetown Law Faculty Publications and Other Works

The particular problems of content and viewpoint discrimination rarely surface in copyright, though some people have argued that fair use implicates them. Nonetheless, one important lesson for copyright from public forum doctrine is that First Amendment law can take some - though not many - speech-related options off the table. In this brief comment, I argue that analogies between copyright law and public forum doctrine highlight important shared commitments to free and robust public discourse, but also substantial practical barriers to judicial enforcement of those commitments.

What’S International Law Got To Do With It? Transnational Law And The Intelligence Mission, James E. Baker

Georgetown Law Faculty Publications and Other Works

The United States faces an immediate and continuous threat of terrorist attack using weapons of mass destruction, including nuclear weapons. The intelligence function and national security law, including international law--or more accurately transnational law--are central to addressing this threat. Indeed, international law is more relevant today in addressing this threat than it was before September 11. Part II of this article describes a continuum of contemporary threats to U.S. national security, with a focus on nonstate terrorism. Part III addresses the role of intelligence and national security law, and in particular law addressed to process, in combating these threats. Part …

The Federal “Claim” In The District Courts: Osborn, Verlinden, And Protective Jurisdiction, Carlos Manuel Vázquez

Georgetown Law Faculty Publications and Other Works

In the title of his influential article, “The Federal ‘Question’ in the District Courts,” Professor Paul Mishkin reminded us that the phrase “federal question” is a misnomer as a description of the “arising under” jurisdiction of the district courts. The purpose of the “arising under” jurisdiction of the district courts is not solely, or even primarily, to resolve disputed questions of federal law, but to provide a hospitable forum for the vindication of federal rights. Such rights can be frustrated by an inhospitable forum not just through the misinterpretation of federal law, but through misinterpretation of state law or through …

Towards Efficient Computation Of Quality Bounded Solutions In Pomdps: Expected Value Approximation And Dynamic Disjunctive Beliefs, Pradeep Reddy Varakantham, Rajiv Maheswaran, Tapana Gupta, Milind Tambe

Research Collection School Of Computing and Information Systems

While POMDPs (partially observable markov decision problems) are a popular computational model with wide-ranging applications, the computational cost for optimal policy generation is prohibitive. Researchers are investigating ever-more efficient algorithms, yet many applications demand such algorithms bound any loss in policy quality when chasing efficiency. To address this challenge, we present two new techniques. The first approximates in the value space to obtain solutions efficiently for a pre-specified error bound. Unlike existing techniques, our technique guarantees the resulting policy will meet this bound. Furthermore, it does not require costly computations to determine the quality loss of the policy. Our second …

Exploring The Causality Between The Pollution Haven Hypothesis And The Environmental Kuznets Curve, Brian W. Jbara '07

Honors Projects

In recent years, increased economic development, globalization, and liberalization of international trade have been linked by economists and environmental scholars as possible causes for specific trends in pollution. One of the most studied and controversial hypotheses is the Environmental Kuznets Curve Hypothesis (EKC), which states that a country's pollution concentrations rise with development and industrialization up to a certain point, after which they fall again as the country uses its increased affluence to reduce pollution concentrations again. If true, plotting pollution concentrations against income per capita will yield an inverted V-the EKC. Another controversy is the manner in which the …

Analyzing The Relationship Between Change In Money Supply And Stock Market Prices, Biniv Maskay '07

Honors Projects

This paper examines the relationship between change in the money supply and the level of stock prices. This paper also dichotomizes change in the money supply into anticipated and unanticipated change and analyzes each of their relationships with stock market prices. Competing theories exist on how change in the money supply affects stock prices. The real activity theorists argue that change in the money supply and stock prices are positively related, where as the Keynesian economists argue otherwise. This study finds a positive relationship between change in the money supply and stock prices, agreeing with the real activity theorists. Economists …

The Best Defense: Why Elected Courts Should Lead Recusal Reform, Deborah Goldberg, James Sample, David E. Pozen

Hofstra Law Faculty Scholarship

In recent years, we have seen an escalation of attacks on the independence of the judiciary. Government officials and citizens who have been upset by the substance of judicial decisions are increasingly seeking to rein in the courts by limiting their jurisdiction over controversial matters, soliciting pre-election commitments from judicial candidates, and drafting ballot initiatives with sanctions for judges who make unpopular rulings. Many of these efforts betray ignorance at best, or defiance at worst, of traditional principles of separation of powers and constitutional protections against tyranny of the majority.

The attacks are fueled in part by the growing influence …

Regulation Of Foxo Stability And Activity By Mdm2 E3 Ligase, Wei Fu

USF Tampa Graduate Theses and Dissertations

Members of the forkhead class O (FOXO) transcription factors are tumor suppressors and key molecules that control aging and lifespan. The stability of mammalian FOXO proteins is controlled by proteasome-mediated degradation but general ubiquitin E3 ligases for FOXO factors remain to be defined. The current studies demonstrate that MDM2 bound to FOXO1 and FOXO3A and promoted their ubiquitination and subsequent degradation, a process apparently dependent on FOXO phopshorylation at PKB sites and on the E3 ligase activity of MDM2. The binding occurred between endogenous proteins and was involved the forkhead box of FOXO1 and the region of MDM2 that controls …

Philosophy Of New Jazz: Reconstructing Adorno, Dustin Bradley Garlitz

USF Tampa Graduate Theses and Dissertations

Theodor W. Adorno, the towering twentieth century German intellectual figure and distinctive musical thinker, was legendary for being over-critical of jazz music. Through a consideration at his admiration for avant-garde chamber and symphonic music, I plan to develop a position that, surprisingly, points towards a theory of unacknowledged acceptance of jazz. The style of jazz that will be the newly constructed musical idiom of admiration for Adorno will be of the heterodox variety. My method of reconstruction will be to interrogate the inconsistencies in Adorno's critical musical writings, and negate such negations with factual evidence of affirmation found in the …

Do You See What I Mean? Measuring Consensus Of Agreement And Understanding Of A National Weather Service Informational Graphic, Lorna M. Geggis

USF Tampa Graduate Theses and Dissertations

Media use of hurricane graphics to apprise populations vulnerable to severe weather provides a persuasive demonstration of the importance and complexity of visual communication. Surprisingly little research, however, has explored how audiences interpret weather graphics. This study examined whether the general public and the National Weather Service share a common understanding of selected weather related terms and meaning of a NWS informational graphic. Using a coorientation model, general public responses to a questionnaire were compared to definitions prescribed by the NWS. Additionally, the public were asked questions to measure trust of the NWS as a credible and reliable source of …

A Paradox Of Diversity: Billions Invested, But Women Still Leave, Rebekah S. Heppner

USF Tampa Graduate Theses and Dissertations

In 2005, women made up 46.4 percent of the United States labor force but only 1.6 percent of Fortune 500 CEOs (Catalyst 2006). Although gains have been made since the passage of the Civil Rights Act in 1964, there is clearly something stopping women from equal representation at the top. Since the late 1980s, businesses have spent billions of dollars on initiatives designed to assist them in dealing with the anticipated increase in the "diversity" of their workplaces (Lubove 1997; Stodghill II 1996; Johnston and Packer 1987). Is there potential for diversity initiatives to help women conquer the "glass ceiling?" …

Mathematical Techniques For The Estimation Of The Diffusion Coefficient And Elimination Constant Of Agents In Subcutaneous Tissue, Lawrence T. Hersh

USF Tampa Graduate Theses and Dissertations

The purpose of this work was to develop methods to estimate the diffusion coefficient and elimination constant for dexamethasone in subcutaneous tissue. Solutions to the diffusion equation were found for different conditions relevant to implantation and injection. These solutions were then used as models for measured autoradiography data where the unknown model parameters were the diffusion coefficient and the elimination constant. The diffusion coefficient and elimination constant were then estimated by curve fitting the measured data to these models. Having these estimates would be of practical importance since inflammation surrounding implantable glucose sensors may be controlled through local release of …

The Effects Of Organizational Structure On Faculty Job Performance, Job Satisfaction, And Counterproductive Work Behavior, Stacey R. Kessler

USF Tampa Graduate Theses and Dissertations

Organizational researchers focus on group level variables such as organizational climate and organizational structure. The purpose of the current meso-level study is to examine the effects of the structure of an academic department on faculty members' job performance, job satisfaction, and prevalence of counterproductive work behavior (CWB), or harmful behaviors while at work. The sample consisted of 1135 full time faculty members working in 229 academic departments throughout the United States and Canada. Results of the study suggested that faculty members working in a more organically structured department report higher levels of job satisfaction. Additionally, productive faculty members working in …

The “Dark Side” Of Ocb: Examining The Relationship Between Citizenship Behavior And Work-To-Family Conflict, Rebecca H. Klein

USF Tampa Graduate Theses and Dissertations

Research on organizational citizenship behaviors (OCB) has focused on the positive aspects of the construct, neglecting the possibility that individuals who engage in OCB may suffer negative consequences. Thus, the present study expands the literature by examining the possibility that OCB is also related to negative individual-level factors, such as work-to-family conflict (WIF). In a replication and extension of Bolino and Turnley's (2005) research, the present study offers an in-depth analysis of the relationship between OCB and WIF, examining two potential mediators (work time and role overload) and two potential moderators (gender and perceptions of OCB as discretionary). Two hundred …

Meaning Makers Make It: Ambivalence About Ambiguity In Academic Discourse, David Haldane Lee

USF Tampa Graduate Theses and Dissertations

This thesis is a broad survey of the uses of ambiguity in academic discourse. I note the uses of ambiguity in literary criticism, linking ambiguity with epistemic relativism. Then I pose the question, is the notion of "reframing" in psychotherapy analogous to the concept of "spin" in propaganda, advertising and public relations? In a consideration of theories that posit the social construction of reality, I examine articles by Judith Butler and Ian Hacking, noting the ambiguous reception of performativity and nominalism, respectively, within academia. In 1996 a physicist named Alan Sokal published an article which argued that reality is a …

Transient Fluorescence Spectroscopy And Laser Induced Fluorescence Lifetimes Of Terbium Doped Dipicolinic Acid, Anali Makoui

USF Tampa Graduate Theses and Dissertations

Using In Situ Click Chemistry To Modulate Protein-Protein Interactions: Bcl-XL As A Case, Lisa M. Malmgren

USF Tampa Graduate Theses and Dissertations

Protein-protein interactions are central to most biological processes. Although in the field of drug discovery there is a great interest in targeting protein-protein interactions, the discovery and development of small-molecules, which effect these interactions has been challenging. The purpose of this project is to determine if in situ click chemistry is a practical approach towards testing whether Bcl-XL is capable of assembling it's own inhibitory compounds. Abbott laboratories developed compound ABT-737, which binds with high affinity (Ki < 1 nM) to the binding sites of Bcl-XL.³⁶. Based on ABT-737, two acetylene anchor molecules AM3 and AM4 have been synthesized. These anchor molecules are distinguished by the reactivity …

USF Tampa Graduate Theses and Dissertations

The state of the art in artificial micro self assembly concepts are reviewed. The history of assembly is presented with a comparison to macro assembly, which has been widely studied, and micro self assembly. Criteria were developed and tested to show that macro assembly is more complex in ways that micro self assembly is not. Self assembly requirements for successful and complex self assembly, which evolved from the macro and micro comparison, are also established and tested. A method to assemble complex structures in the micro scale is proposed and demonstrated at the meso scale. The basic concepts of self …

Effects Of Corrosion On Steel Reinforcement, David Ostrofsky

USF Tampa Graduate Theses and Dissertations

Corroded steel in concrete is a structural issue that plaques concrete structures in coastal regions. Traditionally corroded steel strength is calculated from a distributed area loss due to corrosion over the entire surface of the steel and reducing the capacity accordingly. In reality, corrosion attacks localized regions creating pits and reducing the cross section in a small region which amplifies the effects of corrosion. Stress concentrations at the corrosion pitting damage may further reduce the tensile capacity of the steel. A study of corrosion damage and strength associated with pitting damage can assist in understanding the ultimate tensile capacity of …
