From At&T To Brand X Declining Checks And Balances In An Increasingly Complex Marketplace, Ross G. Hicks
From At&T To Brand X Declining Checks And Balances In An Increasingly Complex Marketplace, Ross G. Hicks
The University of New Hampshire Law Review
When President Clinton signed the Telecommunications Act of 1996, he used the same pen that President Eisenhower used to sign legislation for the Interstate Highway system into law. It was a fitting analogy. In the same way that the interstate road system was expected to open up interstate commerce, the Internet system was expected to open up electronic commerce. In signing the 1996 legislation into law, President Clinton and Congress were updating the regulatory and legislative framework to adapt it to the new realities and opportunities provided by the Internet. The legislation noted that broadband access to the Internet was …

Thermal Failure Mechanism And Voltammetry Metrology For Cu/Barrier/Low K Integration, Dongmei Meng
Thermal Failure Mechanism And Voltammetry Metrology For Cu/Barrier/Low K Integration, Dongmei Meng
Material Science and Engineering Dissertations - Archive
The present study investigates the thermal stability of Cu/barrier/porous low κ (PLK) integration first, and then a new characterization method based on voltammetry is developed to characterize quality of diffusion barrier and pore structure in low κ materials and its thermal stability. The study of thermal stability reveals that Cu/barrier/PLK interconnect fails by Cu out-diffusion through the defects of diffusion barrier into the PLK structure, which is driven by oxidation and stress gradient within the interconnect structure. The failure appears to be triggered by defects in diffusion barrier, however, such defects are not effectively detected by TEM observation due to …
Preparation And Characterization Of Properties Of Electrodeposited Copper Oxide Films, Longcheng Wang
Preparation And Characterization Of Properties Of Electrodeposited Copper Oxide Films, Longcheng Wang
Material Science and Engineering Dissertations - Archive
Copper oxides, including cuprous oxide and cupric oxide, are prepared by electrochemical deposition. The structural, optical and electrical properties of as-deposited copper oxides are evaluated, based on which cuprous oxide is selected as a promising material for photovoltaic applications. Electrodeposited cuprous oxide is a p-type semiconductor with a direct band gap of 2.06 eV. The mechanism of how pH affects the structural and electrical properties of electro-deposited cuprous oxide films is studied. In the pH range of 7.5 to 12.0, there are three different preferred crystal orientations: (100), (110) and (111). With different orientations, cuprous oxide shows different surface morphology …

Mechanical and Aerospace Engineering Theses - Archive
The project considers the problem of motion synchronization of free flying robotic spacecraft and serviceable floating objects in space. The synchronization maneuvers are based on sample and hold nonlinear translational and attitude control laws. GPS pseudorange signals and a vision based sensor unit are modeled to give position measurements; position and velocity estimates are extracted from the measurements based on Extended Kalman Filter models. A sensor data fusion algorithm in the form of a Federated Extended Kalman Filter is implemented that blends the estimates of the individual filters into a global estimate. Nonlinear simulations where a Pursuer spacecraft attempted to …
Enhancement Of Pool Boiling Heat Transfer Using Thermally-Conductive Microporous Coating Techniques, Joo Han Kim
Enhancement Of Pool Boiling Heat Transfer Using Thermally-Conductive Microporous Coating Techniques, Joo Han Kim
Mechanical and Aerospace Engineering Dissertations - Archive
The present research is an experimental study of the enhancement of boiling heat transfer using microporous coating techniques. The current research is divided into four major phases. During the first phase, the effects of different metal particle sizes in the coating compound for thermally non-conductive microporous coating on pool boiling performance of refrigerants and water are investigated. The test surfaces, solid copper blocks with 1-cm² base, were tested at atmospheric pressure in saturated FC-72, R-123, and water. Results showed that the surface treatment by non-conductive microporous coating significantly enhanced both nucleate boiling and critical heat flux of all three refrigerants. …
Flexible Microfluidic Circuit With Embedded In-Plane Valve, Srikar C. Paruchuri
Flexible Microfluidic Circuit With Embedded In-Plane Valve, Srikar C. Paruchuri
Mechanical and Aerospace Engineering Theses - Archive
Recent developments in Microfluidic systems have demonstrated many potential applications related to biology, chemistry and medical sciences. Fluidic manipulation with precise volume control is a basic function in these systems, and microvalves play an important role in control and delivery of the fluid sample. One of the key issues in such valve design is to make large membrane deflections compared to the channel dimension. This thesis reports a flexible microfluidic chip with embedded in-plane valves for fluid manipulation. Silicone elastomer (Polydimethylsiloxane - PDMS) is one of the most suitable materials to fabricate microvalve membranes, because of its low Young's modulus, …
Tracing And Replay Of Real-Time Concurrent Programs In Vxworks, Daxa Keshavji Patel
Tracing And Replay Of Real-Time Concurrent Programs In Vxworks, Daxa Keshavji Patel
Computer Science and Engineering Theses - Archive
Real-time concurrent programs are difficult to analyze, debug and test because of the existence of race conditions. In particular, cyclic debugging requires the ability to reproduce a failed execution. That is, when a failure is observed during a test run, it is often necessary to reproduce the test run as an effort to locate the bug that has caused the failure. However because of the variations in thread scheduling and signal latency, a real-time concurrent execution may not be reproduced simply by re-executing the program under test. In this thesis, we describe a language-based framework for tracing and replay of …
Performance Analysis Of The Beacon Period Contraction Mechanism In Wimedia Mac For Uwb, Shenjin Sun
Performance Analysis Of The Beacon Period Contraction Mechanism In Wimedia Mac For Uwb, Shenjin Sun
Computer Science and Engineering Theses - Archive
The WiMedia MAC for UWB based WPANs is currently preferred among standards for wireless network since it requires non-infrastructure for ad hoc network, and also supports for Quality of Service (QoS). Without infrastructure, coordination of devices within radio range is achieved by the exchange of beacon frames, which is an overhead in WiMedia MAC, since no data transmission is allowed during Beacon Period (BP). In a dynamic network, devices might leave or join in, so beacon slots will be released or reoccupied with the changing of network. And BP contraction mechanism is aimed at reusing the released beacon slots in …
Computer-Aided Patient Specific Treatment Planning Of Cryosurgery For Breast Cancer, Junkyu Jung
Computer-Aided Patient Specific Treatment Planning Of Cryosurgery For Breast Cancer, Junkyu Jung
Mechanical and Aerospace Engineering Theses - Archive
Cryosurgery, which is to destroy tumors by use of localized freezing, is an emerging treatment modality for breast cancer as the size of detectable tumor becomes smaller due to more frequent use of various diagnostic imaging including MRI, CT and mammogram. Although general surgical guideline has been developed and its effectiveness has been demonstrated, cryosurgical protocol should be adjusted for a given patient to accommodate patient-specific variations including tumor size, location and geometry of patient's breast. In this study, a computerized treatment planning tool was developed to aid surgeons to determine surgical parameters considering patient specific diagnostic information. This tool …
Freezing-Induced Microstructural Changes Of Collagen Scaffolds, Jeffrey David Miller
Freezing-Induced Microstructural Changes Of Collagen Scaffolds, Jeffrey David Miller
Mechanical and Aerospace Engineering Theses - Archive
Understanding the effects of freezing on the functional properties of tissues is critical to cryopreservation of native and artificial tissues, and prognosis after cryotherapies. Although investigations have been performed to correlate macroscopic properties such as mechanical properties with freezing parameters, the effects are typically tissue-type dependent and no physical understanding is available to explain these effects. Since the mechanical and optical properties of a tissue are based on the characteristics of its extracellular matrix (ECM), understanding and quantifying these changes could assist in predicting the response a tissue will have to freezing under different circumstances. In this study, the microstructural …

Immigration And Editorial Page Policy: A Case Study Of The Dallas Morning News, Anthony Ellis Hartzel
Public Affairs Theses - Archive
Newspaper editorial pages play a crucial role in democratic society, serving as forums for informed debate. On major issues such as immigration, many factors are at play when members of an editorial board sit down together to shape the institutional voice of their newspaper. Using the explanatory case study method, the author directly observes editorial board deliberations at the Dallas Morning News, and sheds light on the influences that affect those writers and editors before the paper publishes its formal positions. The thesis finds that many influences exist beyond news judgment. Those influences range from intra-group dynamics and corporate management, …
Micromechanical Analysis Of Yielding For Particulate Filled Composites, Chih-Ta Chen
Micromechanical Analysis Of Yielding For Particulate Filled Composites, Chih-Ta Chen
Material Science and Engineering Theses - Archive
Particulate filled composites are hybrid materials which consist of particulates held together by a matrix. In this thesis, a simulation method to obtain overall failure criterion for particulate filled composites based on the computer software "MATHEMATICA" will be presented. The composite is assumed to fail at the matrix just outside the inclusion. By Self-Consistent Method, the composite can be imaged as an inclusion embedded within effective matrix. The Equivalent Inclusion method is then applied to stimulate the stress field within the inclusion. Stress just outside inclusion can be calculated because interfacial traction force on the boundary of inclusion is continuous. …
Spatial Patterns And Determinants Of Industrial Regional Growth In Mexico, 1993-2003: Implications For Regional Planning And Public Policy, Jesus Antonio Trevino
Spatial Patterns And Determinants Of Industrial Regional Growth In Mexico, 1993-2003: Implications For Regional Planning And Public Policy, Jesus Antonio Trevino
Planning Dissertations - Archive
This research investigates industrial regional growth and its determinants in Mexico from 1993 to 2003. Strategies of local economic development, usually based on industrial promotion, require knowing main determinants of industrial regional growth. The case study shows that there is no variable with a systematically strong effect for all industries which policymakers and planners might directly control. This finding warns us about generic policy designs uncritically based on outcomes from other experiences. Although these results show a complex problem in terms of regional policy, some recommendations for industrial spatial distribution may, however, be derived from this study. For instance, during …
School Responses To High-Stakes Testing, Mishuk Anwar Chowdhury
School Responses To High-Stakes Testing, Mishuk Anwar Chowdhury
Economics Theses - Archive
This paper analyzes school's responses to high stakes testing. Using a grade level panel dataset from Texas Assessment of Knowledge and Skills (TAKS) for reading and math tests for 2003 through 2006, to find schools responses to failure. I find that there is a tendency for schools to shift resources from subjects that they pass to subjects that they fail. I classify schools' responses as either substitution responses or scale responses. A school has a substitution response if, when it fails to meet the state's required passing rate threshold for one subject for one cohort of students, it shifts resources …
Risk, Resilience And Relocation: A Life Course Exploration Of Resettlement Experiences Of Public Housing Residents, Jan H. Johnston
Risk, Resilience And Relocation: A Life Course Exploration Of Resettlement Experiences Of Public Housing Residents, Jan H. Johnston
Public Affairs Dissertations - Archive
Spatial deconcentration of poverty has been the organizing framework of federally subsidized housing policy for well over a decade. During that time low-income families living in traditional public housing across the country have been involuntarily relocated. Household relocation into lower poverty middle class, while the underlying mobility goal, has proven difficult for many families. We continue to look for evidence for how and whether these families are able to adapt as they are scattered across urban settings. The research focus was to operationalize the resident's adaptive behavior pertaining to deconcentration of poverty by trait difference, familial/cultural cues and perceived institutional …

Perceptions Of Crime, Fear Of Crime, And Defensible Space In Fort Worth Neighborhoods, Bonnie R. Grohe
Public Affairs Dissertations - Archive
This research used descriptive, written scenarios to test the perceptions of crime, fear of crime, and defensible space of residents in three Fort Worth, Texas, neighborhood associations. The survey instrument included two different measures of fear of crime: 1) fear of crime in hypothetical scenarios, and 2) fear of crime in resident's own neighborhoods to examine whether residents who were fearful in their own neighborhood also reported high levels of fear in hypothetical neighbor¬hoods. The instrument also tested whether residents perceived certain neighborhoods as defensible and if residents recognized what crime prevention scholars defined as "safe" environments. The multiple regression …

Spectroscopic Characterization Of Biliary Tract Tissues In-Vivo To Assist Laparoscopic Cholecystectomy, Sarita Kommera
Spectroscopic Characterization Of Biliary Tract Tissues In-Vivo To Assist Laparoscopic Cholecystectomy, Sarita Kommera
Bioengineering Theses - Archive
Laparoscopic Cholecystectomy is a surgical method for removal of gallbladder when it is diseased with gall stones. Almost 750,000 people are affected with this disease annually in USA. Gall bladder is removed by placing an incision on the cystic duct. This duct is totally embedded in fat (which is a few mm thick) in most of the cases and it becomes a huge problem decreasing the visual capability of the surgeon to distinctly locate the duct. Near Infrared Spectroscopy (NIRS) can solve the fuzziness as it penetrates in a few mm thick tissues. NIRS is one of the simplest techniques …

Viewing New Product Development Through The Real Options Lens: An Empirical Investigation Of The Market Reaction And The Role Of Contextual Factors, Vivek Shankar Natarajan
Marketing Dissertations - Archive
New product development is an important strategic decision for marketing managers. This study examined new product development related decisions by employing a real options framework. Specifically, new product development decisions are viewed as either an options creation or options exercise process. It evaluated the various types of new product decisions- development of new products, launching of new products, delaying launch of new products and exiting the market by using a real options lens. In doing so, the study sought to answer two research questions: 1. How does the market react to creation and exercise of real option? 2. How do …
Novel Intraocular Drug Delivery System For The Prevention Of Posterior Capsule Opacification, Brett Thomes
Novel Intraocular Drug Delivery System For The Prevention Of Posterior Capsule Opacification, Brett Thomes
Bioengineering Dissertations - Archive
Posterior capsule opacification (PCO) is a major complication associated with the implantation of intraocular lens (IOLs). Evidence suggests that PCO formation is caused by abnormal lens epithelial cell (LEC) migration/proliferation. We hypothesize that pharmacologic agents must target inflammatory cells in addition to LECs to inhibit PCO formation. To successfully target both inflammatory cells and LECs, a novel intraocular drug delivery system (DDS) was developed for implantation in the lens capsular bag. Such a system permits direct delivery of anti-inflammatory and anti-proliferative drugs in the lens capsule for extended periods of time resulting in reduced PCO formation. A lubricious polyurethane coating …
A Comprehensive Study Of The Effects Of Eeg Electrode Arrays On Mri Signal-To-Noise At 3t, Aman Ish Goyal
A Comprehensive Study Of The Effects Of Eeg Electrode Arrays On Mri Signal-To-Noise At 3t, Aman Ish Goyal
Bioengineering Theses - Archive
Simultaneous EEG-fMRI offers much potential for gaining complementary, noninvasive information about brain function. While much effort has been devoted to the compelling problem of removing ballistocardiogram and gradient artifacts from the EEG waveforms, less attention has been paid to the impact that increasing density of electrode arrays has on the MR images. Initial work reporting the effects of EEG caps and electrodes on the MR image has been site specific, using customized EEG equipment that those research groups built in-house. Therefore these results are hard to generalize to other laboratory environments. A monotonic decrease in SNR of the images has …
