On Conflict Of Human Rights, Xiaobing Xu, George Wilson

The University of New Hampshire Law Review

[Excerpt] “This article supports Gewirth’s view: that is, the reason why utilitarian values such as national security, public safety, public order, public health, and public morality may outweigh human rights is that they contain human rights elements. Thus, as a rule, whenever human rights clash with nonrights value considerations, we should analyze whether they contain human rights elements. If they do, they may override human rights that conflict with them. If they do not, they cannot.”

Videoconferencing In Immigration Proceedings, Aaron Haas

The University of New Hampshire Law Review

[Excerpt] “When there is mention of a legal trial, a certain picture naturally comes to mind. One sees a judge in his black robe sitting on a raised bench. Lawyers are stationed at tables on either side of the courtroom, prepared to present their arguments to the court. A jury box may sit off to the side, holding a cross-section of citizens culled from the population to perform their ancient duty. The courtroom is made of fine wood and polished marble, and it is adorned with the accouterments of justice—American flags, seals, paintings of honored jurists—which let an observer know …

Stealing What's Free: Exploring Compensation To Body Parts Sources For Their Contribution To Profitable Biomedical Research, Jo-Anne Yau

The University of New Hampshire Law Review

[Excerpt] “At first blush, donating body parts in the name of science appears to be a beautiful solution to the problem of scarce body parts for research advancements. But a closer investigation reveals an ugly fact: the philanthropic donors—referred to as “Sources” in this article—are subjected to physical and financial exploitation.

Sources play a crucial and indispensable role in biotechnology. Without human body parts, most medical discoveries would not have been possible. Handsome profits can be derived from successful discoveries. But currently in the United States, when a Source provides body parts for research purposes, the researcher, research foundation, and …

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

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

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 …

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

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

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

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

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

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

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 …

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. …

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 …

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

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 …

Observer Synthesis For Linear/Nonlinear Dynamical Systems Subject To Measurement Delays, Praveen C. Muralidhar

Electrical Engineering Theses - Archive

In this research, problems associated with communication delays on the stability of formation of a group of unmanned vehicles is examined and solution to this problem is proposed. Ideally, it is required that the information transfer between the vehicles participating in a cooperative task be available immediately. But, in reality, there is always a delay between the instants at which the information is transmitted by one vehicle and the instant at which it is received by the other vehicles in the formation. A state observer is used to estimate the time delayed signal. The observer consists of two dynamic systems …

Design Of A One Day Workshop On Intuition, Alexander Von Reumont

Creativity and Change Leadership Graduate Student Master's Projects

Intuition has been basically an untouched field in the domain of creativity research. I therefore wanted to investigate intuition in this study from scratch. I wanted to find out what laymen, as well as experts in the field of creativity knew about intuition, what their perceptions and expectations were, and what they wanted to know and learn about it in the future. The purpose of this study was twofold. First, to find rational explanations for intuition which support my hypothesis that it is a wildly neglected but natural and highly influential part of our intelligence. Second, to develop a one …

Design Of Novel Experimental Techniques To Investigate The Formation Of Nanoparticle-Based Tribofilms, Corey Thompson

Mechanical Engineering Undergraduate Honors Theses

Nano-engineered lubricant additives such as organically-active nanoparticles of molybdenum disulphide (Hybrid-milled MoS2) are becoming increasingly popular in the fight against harsh friction and wear that occurs during boundary-layer lubrication. A previous paper (Verma, 2007), has reported improvements in both coefficient of friction and wear scar diameter; however, there exists very little data concerning the methods through which this improvement is achieved. Using techniques such as atomic force microscopy (AFM), nanoindentation, scanning electron microscopy (SEM), focused ion beam (FIB), high resolution transmission electron microscopy (HRTEM) as well as tribometery, the chemical and mechanical characteristics of the nanoparticle based tribofilm are characterized. …

Decision Support Systems In Product Development: A Batesian Network Approach For Injection-Molded Products, Jason S. Trahan

Dissertations

Attribute defects cause a majority of the scrap for many manufacturers injection-molding aesthetic parts, yet these defects receive little attention duringproduct development. Methods for preventing attribute defects have been hampered by the inability to quantify complex cause-effect relationships. However, the qualities of a burgeoning branch of knowledge-based systems, called Bayesian networks, have benefited various fields faced with similar circumstances.Bayesian networks have the capability of presenting causal relationships between variables in a graphical structure and quantitatively explaining their effects throughout that structure. These effects can be characterized by probabilities derived from sources, such as equations, historical data, rules-of-thumb or expert knowledge. …
