Decreasing Time To Market For A Medical Device: New Methods For The Product Development Process, Kelly Marie Davis

Doctoral Dissertations

"Through an example, led at a leading medical device company, this dissertation will demonstrate that by applying certain lean principals and tools to the development of a medical device, shortened development times can be obtained. The two papers presented in the dissertation will fill a gap in current literature. Literature presents lean techniques and applications used in many different industries. But, due to the uniqueness of the medical device industry, these general techniques are not ideal. New methods will be used and validated at a medical device company, Covidien. Instead of trying to implement many general lean principals to their …

Design And Experimental Study Of Turbo Equalization For Multiple Antenna Systems, Amirhossein Rafati

Doctoral Dissertations

"Multiple-input multiple-output (MIMO) wireless communication systems have attracted a lot of interest in the past decade due to their capability in delivering high spectral efficiency as well as their robust performance against fading. In MIMO inter-symbol interference (lSI) channels, a severe interference problem occurs due to the lSI and co-channel interference. Thus, the error propagation problem becomes more serious, and its mitigation has to be considered when designing the receiver. In this regard, a turbo equalizer which exchanges soft information between the equalizer and the decoder has been shown to be an effective method to combat the lSI caused by …

Impact Of Plug-In Hybrid Electric Vehicles On The Power Grid In A Smart Environment, Zahra Darabi

Doctoral Dissertations

This dissertation focuses on the interactions between plug-in hybrid electric vehicles (PHEVs) and the power grid. This study has used the data available through the national household travel survey (NHTS) to obtain realistic information such as the arrival time of vehicles, miles driven, and vehicles types. After data manipulation, the aggregated PHEV charging load profiles (PCLP) have been developed. The results show that the peak of PCLP overlaps with the domestic load peak. In order to alleviate this issue, several charging policies have been developed and their impacts on PCLP have been investigated. As a next contribution, the data obtained …

Identification And Visualization Of Electromagnetic Coupling Paths & Nonlinear Capacitors For Esd Protection, Hongyu Li

Doctoral Dissertations

"The first topic of this dissertation focuses on developing methods to identify and visualize electromagnetic coupling paths. The basis of the approach is to utilize an analogy between electromagnetic energy flow and fluid flow. This allows one to apply the theories and algorithms of fluid dynamics to electromagnetics and thereby to visualize the electromagnetic energy flow. This in turn can be utilized to identify the electromagnetic coupling path.

The second topic of this dissertation investigates the nonlinearity of capacitors and suggests improved trade-off between electrostatic discharge (ESD) protection and data bandwidth by using the antiferroelectric (AFE) capacitors as ESD protection. …

Handel's Maser-Solution Theory Of Ball Lightning: The Creation Of Stable Three-Dimensional Cavitons By An Atmospheric Maser With An Open Resonator, Glenn Andrew Carlson

Doctoral Dissertations

"This dissertation develops details of Handel's Maser-Soliton Theory of ball lightning. The atmosphere between a thundercloud and the Earth's surface is modeled as an idealized stable open resonator with water vapor as the active medium and the thundercloud and Earth's surface as reflecting surfaces. The stable resonator generates a maser beam that narrows to the beam waist at the Earth's surface, which is assumed to be planar. Two candidate rotational transitions are identified within the v₁v₂v₃ = 010 vibrational band of water having wavelengths of 13.9 cm and 1.12 cm, and relevant spectroscopic parameters are retrieved from the HITRAN 2008 …

Meaning, Purpose, And Cause In The Law Of Deception, Gregory Klass

Georgetown Law Faculty Publications and Other Works

Laws designed to affect the flow of information take many forms: rules against misrepresentation, disclosure requirements, secrecy requirements, rules governing the formatting or packaging of information, and interpretive rules designed to give people new reasons to share information. Together these and similar rules constitute the law of deception: laws that aim to prevent or cure deception. One encounters similar problems of design, function and justification throughout the law of deception. Yet very little has been written about the category as a whole. This article begins to sketch a general theory. It identifies three regulatory approaches. Interpretive laws, such as common …

The Limits Of Government Regulation Of Science, John D. Kraemer, Lawrence O. Gostin

Georgetown Law Faculty Publications and Other Works

The recent controversy over the National Science Advisory Board for Biosecurity’s (NSABB) request that Science and Nature redact key parts of two papers on transmissible avian (H5N1) influenza reveal a troubled relationship between science and security. While NSABB’s request does not violate the First Amendment, efforts to censor the scientific press by force of law would usually be an unconstitutional prior restraint of the press absent a compelling state interest. The constitutional validity of conditions on grant funding to require pre-publication review of unclassified research is unclear but also arguably unconstitutional.

The clearest case where government may restrict publication is …

The First Amendment’S Borders: The Place Of Holder V. Humanitarian Law Project In First Amendment Doctrine, David Cole

Georgetown Law Faculty Publications and Other Works

In Holder v. Humanitarian Law Project, the Supreme Court’s first decision pitting First Amendment rights against national security interests since the terrorist attacks of September 11, 2001, the Court appears to have radically departed from some of the First Amendment’s most basic principles, including the maxims that speech may not be penalized because of its viewpoint, that even speech advocating crime deserves protection until it constitutes incitement, and that political association is constitutionally protected absent specific intent to further a group’s illegal ends. These principles lie at the core of our political and democratic freedoms, yet Humanitarian Law Project …

Military Lawyers And The Two Cultures Problem, David Luban

Georgetown Law Faculty Publications and Other Works

Military and humanitarian lawyers approach the laws of war—labeled “law of armed conflict” by the former and “international humanitarian law” by the latter—in very different ways. For military lawyers, the starting point is military necessity, and the reigning assumption is that legal regulation of war must accommodate military necessity. For humanitarian lawyers, the starting point is human dignity and human rights. This article argues that from these radically different axioms legal consequences systematically follow regarding treaty interpretation, the sources and reach of customary international law, the nature of international law, deference and discretion to military commanders, and the connection between …

The Eye Alone Is The Judge: Images And Design Patents, Rebecca Tushnet

Georgetown Law Faculty Publications and Other Works

Design patents are an area of intellectual property law focused entirely on the visual, unlike copyright, patent, trademark, trade secret, or the various sui generis protections that have occasionally been enacted for specific types of innovation. Judges and lawyers in general are highly uncomfortable with images, yet design patents force direct legal engagement with images. This short piece offers an outsider’s view of what design patent law has to say about the use of images as legal tools, why tests for design patent infringement are likely to stay unsatisfactory, and what lessons other fields of intellectual property, specifically copyright, might …

Juvenile Justice After Graham V. Florida: Keeping Due Process, Autonomy, And Paternalism In Balance, Kristin N. Henning

Georgetown Law Faculty Publications and Other Works

Legal disputes involving children invariably evoke a complex matrix of issues such as child and adolescent capacity, individual rights and autonomy, parental authority, and in the criminal justice context-diminished culpability for a minor's actions. While it is difficult to identify a clear and cohesive jurisprudence regarding the balance between children's autonomy and children's vulnerability across Supreme Court cases, a series of cases over the last decade, including Roper v. Simmons, Graham v. Florida, and J.D.B. v. North Carolina, offer a more consistent view of children as vulnerable, malleable, and in need of protection, at least in the …

A Decision Theory Of Statutory Interpretation: Legislative History By The Rules, Victoria Nourse

Georgetown Law Faculty Publications and Other Works

We have a law of civil procedure, criminal procedure, and administrative procedure, but we have no law of legislative procedure. This failure has serious consequences in the field of statutory interpretation. Using simple rules garnered from Congress itself, this Article argues that those rules are capable of transforming the field of statutory interpretation. Addressing canonical cases in the field, from Holy Trinity to Bock Laundry, from Weber to Public Citizen, this article shows how cases studied by vast numbers of law students are made substantially more manageable, and in some cases quite simple, through knowledge of congressional procedure. …

Lessons From Social Psychology For Complex Operations, Rosa Brooks

Georgetown Law Faculty Publications and Other Works

This short essay looks at several social forces that powerfully affect human behavior, often trumping individual “character,” personality, knowledge, and even deeply held moral beliefs. Specifically, this essay looks briefly at issues of obedience, conformity, and group polarization, discussing the ways in which they can affect and distort individual behavior. Ultimately, this essay suggests, understanding these dynamics can have important implications for how we think about counterinsurgency and stability operations.

National Security In The Information Age, Rosa Brooks

Georgetown Law Faculty Publications and Other Works

The information environment has been changing right along with the broader security environment. Today, the information environment connects almost everyone, almost everywhere, almost instantaneously. The media environment has become global, and there’s no longer such thing as “the news cycle” —everything is 24/7. Barriers between US and global publics have virtual disappeared: Everything and anything can “go viral” instantly, and it’s no longer possible to say one thing to a US audience and another thing to a foreign audience and assume no one will ever set the statements side by side. The Pakistani military has a very clear idea of …

Democracy Promotion: Done Right, A Progressive Cause, Rosa Brooks

Georgetown Law Faculty Publications and Other Works

By the beginning of the Obama Administration, democracy promotion had become a rather tarnished idea, and understandably so. Like Islam or Christianity, much blood has been shed beneath its banner. It may be true that democracies don’t go to war with one another, but they certainly go to war, and their wars kill people just as dead as the wars undertaken by illiberal regimes. Anyone on the political left can tell the story: During the Cold War, the United States fought endless proxy wars and engaged in a great deal of overt and covert mischief, all in the name of …

Development Of Kinectᵀᴿ Applications For Assembly Simulation And Ergonomic Analysis, Chinmay Prakash Daphalapurkar

Masters Theses

"Marker-less motion capture technology has been harnessed for several years to track human movements for developing various applications. Recently, with the launch of Microsoft Kinect, researchers have been keenly interested in developing applications using this device. Since Kinect is very inexpensive (only $110 at the time of writing this thesis), it is a low-cost and a promising substitute for the comparatively expensive marker-based motion capture systems. Though it is principally designed for home entertainment, numerous applications can be developed with the capabilities of Kinect. The skeleton data of a human being tracked by a single Kinect device is enough to …

Coaxial Cable Bragg Grating, Jie Huang

Masters Theses

"In order to ensure the continued safe and reliable operation of various civil structures, such as dams, bridges, and buildings, in situ strain monitoring is of great importance, especially for structures that may experience large strains. A new coaxial cable Bragg grating (CCBG) is developed as a strain sensor and the sensor's capacity for large range strain measurement is demonstrated for the first time. The sensor device is comprised of regularly spaced periodic discontinuities along a coaxial cable. The discontinuities are fabricated using a computer numerical controlled (CNC) machine to drill holes in the cable. Each discontinuity generates a weak …

Experimental Feasibility Study Of A Passive Radio Frequency Identification-Based Distributed Beamforming Framework And Radio Frequency Tag Design For Achieving Dynamic Beamforming, Pratim Shah

Masters Theses

"Passive UHF RFID tags works on the principle of backscattering mechanism. In realistic environment, there are multiple objects and tags that create complex, multipath propagation scenarios with numerous null-points, reduced read range and read rate.

In general, the RF frontend of tags could be controlled such that the negative effects of multipath propagation are reduced or even inverted thus implementing a virtual beamforming. The theoretical framework of beamforming in RFID system, using additional tags as virtual antenna arrays, has been discussed before. The presented study evaluates the feasibility of such beamforming in passive RFID systems. Moreover, it synthesizes an appropriate …

Integration Of Multiple Vision Systems And Toolbox Development, Rohit Vijay Bapat

Masters Theses

"Depending on the required coverage, multiple cameras with different fields of view, positions and orientations can be employed to form a motion tracking system. Correctly and efficiently designing and setting up a multi-camera vision system presents a technical challenge. This thesis describes the development and application of a toolbox that can help the user to design a multi-camera vision system. Using the parameters of cameras, including their positions and orientations, the toolbox can calculate the volume covered by the system and generate its visualization for a given tracking area. The cameras can be repositioned and reoriented using toolbox to generate …

Unified Knowledge Model For Stability Analysis In Cyber Physical Systems, Tamal Paul

Masters Theses

"The amalgamation and coordination between computational processes and physical components represent the very basis of cyber-physical systems. A diverse range of CPS challenges had been addressed through numerous workshops and conferences over the past decade. Finding a common semantic among these diverse components which promotes system synthesis, verification and monitoring is a significant challenge in the cyber-physical research domain. Computational correctness, network timing and frequency response are system aspects that conspire to impede design, verification and monitoring. The objective of cyber-physical research is to unify these diverse aspects by developing common semantics that span each aspect of a CPS. The …

Vehicle Path Verification Using Wireless Sensor Networks, Gerry W. Howser

Masters Theses

"Path Verification is a problem where a verifier would like to determine how closely a vehicle actually traversed a path that it claims to have traversed. This problem has critical significances in terms of vehicle mobility. Mobile nodes can be patrols officers or cab drivers, while respective verifiers can be police dispatchers or cab operators. In this paper, we design a sensor network assisted technique for vehicle path verification. In our design, a number of static wireless sensors placed in road segments will serve as witnesses and certify vehicles as they move. Post movement, these witness certificates will be utilized …

The Master Mason: How Professor Baldus Built A Bridge From Learning To Law And The Legacy Of Equal Justice He Leaves Behind, James E. Baker

Georgetown Law Faculty Publications and Other Works

These are Chief Judge Baker’s remarks eulogizing the late Professor David Baldus. Chief Judge Baker observes that Professor Baldus was an extraordinary educator-lawyer who mastered the fields of social science and statistics. He adds that Professor Baldus was diligent in his research and strived to make the law accessible. Chief Judge Baker discusses how Professor Baldus’s research on the death penalty and proportionality review successfully bridged the law and learning, without ever losing sight of compassion.

Reliability Evaluation Of Distribution Systems Containing Renewable Distributed Generations, Abdulaziz Abddullah Alkuhayli

Masters Theses

Reliability evaluation of distribution networks, including islanded microgrid cases, is presented. The Monte Carlo simulation algorithm is applied to a test network. The network includes three types of distributed energy resources solar photovoltaic (PV), wind turbine (WT) and gas turbine (GT). These distributed generators contribute to supply part of the load during grid-connected mode, but supply the entire load during islanded microgrid operation. PV and WT stochastic models have been used to simulate the randomness of these resources. This study shows that the implementation of distributed generations can improve the reliability of the distribution networks.

A mixed-methods study was utilized by the researcher to gather quantitative data through the use of an online survey and to gather qualitative data through subsequent focus-group interviews to address the proposal’s three research questions: (a) What are the differences (if any) between the perceptions of novice elementary, middle, and high school principals regarding the five instructional leadership practices identified by Kouzes and Posner (2003; i.e., challenging the …

Mining Diversity On Social Media Networks, Lu Liu, Feida Zhu, Meng Jiang, Jiawei Han, Lifeng Sun, Shiqiang Yang

Research Collection School Of Computing and Information Systems

The fast development of multimedia technology and increasing availability of network bandwidth has given rise to an abundance of network data as a result of all the ever-booming social media and social websites in recent years, e.g., Flickr, Youtube, MySpace, Facebook, etc. Social network analysis has therefore become a critical problem attracting enthusiasm from both academia and industry. However, an important measure that captures a participant’s diversity in the network has been largely neglected in previous studies. Namely, diversity characterizes how diverse a given node connects with its peers. In this paper, we give a comprehensive study of this concept. …

Determining The Feasibility Of Universal Access To Bus Transportation For Illinois Wesleyan University Students, Liz Kuehn '13

Outstanding Senior Seminar Papers

In a car-based society, transportation has both environmental and economic implications. However, public transportation, and programs like Universal Access that promote public transportation by providing ‘fare free’ access to specific groups in the community, can offer low cost, sustainable alternatives to car-based transportation. The basic concept behind Universal Access is that a community group contracts with the local public transit system to provide unlimited access to public transportation for individuals within the group at a negotiated cost to the group (Toor et. al 2004). The purpose of this study is to determine the feasibility of creating a Universal Access program …
