Artificial Neural Networks For Asymmetric Selective Harmonic Current Mitigation-Pwm In Active Power Filters To Meet Power Quality Standards, Amirhossein Moeini, Morteza Dabbaghjamanesh, Jonathan W. Kimball, Jie Zhang

Electrical and Computer Engineering Faculty Research & Creative Works

The main objective of an active power filter (APF) is to control the harmonics of nonlinear loads in power systems. In addition, the reactive power (fundamental component of the AC power) at the point of common coupling (PCC) can be compensated by using an APF. This paper investigates a technique for the modulation technique of the active power filters. Using the artificial neural network (ANN) technique, real-time fundamental and harmonic compensations can be achieved for the low-frequency modulation techniques such as asymmetric selective harmonic elimination/mitigation-pulse width modulation (ASHE/ASHM-PWM) and asymmetric selective harmonic current mitigation-PWM (ASHCM-PWM). This means that different phases …

Quantitative Assessment Of Glioblastoma Phenotypes In Vitro Establishes Cell Migration As A Robust Readout Of Crk And Crkl Activity., Taeju Park, Neka Large, Tom Curran

Manuscripts, Articles, Book Chapters and Other Papers

The expression levels of CT10 regulator of kinase (Crk) and Crk-like (CrkL) are elevated in many human cancers, including glioblastoma (GBM), and are believed to contribute to poor prognosis. Although Crk and CrkL have been proposed as therapeutic targets in these tumors, the lack of a reliable, quantitative assay to measure Crk and CrkL activity has hindered development of inhibitors. Here, we knocked down Crk, CrkL, or both using small interfering RNAs (siRNAs) in a human GBM cell line, U-118MG, to determine the respective, quantitative contributions of Crk and CrkL to cellular phenotypes. The combined use of specific and potent …

INTRODUCTION: Alport syndrome is a rare genetic disorder that affects as many as 60,000 persons in the USA and a total of 103,000 persons (10,000) in the European Union [1, 2]. It is the second most common inherited cause of kidney failure and is characterized by progressive loss of kidney function that often leads to end-stage kidney disease. Currently, there are no approved disease-specific agents for therapeutic use. We designed a phase 3 study (CARDINAL; NCT03019185) to evaluate the safety, tolerability, and efficacy of bardoxolone methyl in patients with Alport syndrome.

METHODS: The CARDINAL phase 3 study is an international, …

Mining Haul Road Defect Detection -- Advancement In Automated Road Extent And Response Calibration For Improved Maintenance, Alexander David Douglas

Doctoral Dissertations

Mine haul roads degrade rapidly due to extremely heavy loads on sub optimal construction materials. This research tests two methods of defect detection to determine limitations to current technology: optical detection and vehicle vibration response. Optical defect detection was found to have the least significant limitations for surface defect detection and vehicle vibration response modeling has the least significant limitations for subsurface defects. This research proposes novel methods to eliminate the critical limitations of both technologies.

Unmanned Aerial Vehicles (UAV) equipped with GPS and a high-resolution camera is used to create a 3-D point cloud using a structure-from-motion algorithm. This …

Data And Resource Management In Wireless Networks Via Data Compression, Gps-Free Dissemination, And Learning, Xiaofei Cao

Doctoral Dissertations

“This research proposes several innovative approaches to collect data efficiently from large scale WSNs. First, a Z-compression algorithm has been proposed which exploits the temporal locality of the multi-dimensional sensing data and adapts the Z-order encoding algorithm to map multi-dimensional data to a one-dimensional data stream. The extended version of Z-compression adapts itself to working in low power WSNs running under low power listening (LPL) mode, and comprehensively analyzes its performance compressing both real-world and synthetic datasets. Second, it proposed an efficient geospatial based data collection scheme for IoTs that reduces redundant rebroadcast of up to 95% by only collecting …

Fiber-Optic And Coaxial-Cable Extrinsic Fabry-Perot Interferometers For Sensing Applications, Chen Zhu

Doctoral Dissertations

”The fiber-optic extrinsic Fabry-Perot interferometer (EFPI) is one of the simplest sensing configurations and is widely used in various applications due to its prominent features, such as high sensitivity, immunity to electromagnetic interference, and remote operation capability.

Development Of Intelligent Stimuli-Responsive Biomaterials And Nanodevices, Shuo Yang

Doctoral Dissertations

"Structural DNA nanotechnology utilizes DNA molecules as building blocks to fabricate ordered artificial nanostructures at the molecular level. Among all DNA-based techniques, DNA origami has been considered as one of the most powerful tools for constructing artificial nanostructures with excellent programmability and addressability. Currently, most DNA origami nanostructures are static and do not have the ability to response to environmental stimulation. The development of environmental-responsive DNA origami nanostructures is a critical step towards the realization of intelligent dynamic DNA origami-based nanodevices. This research focuses on the design and fabrication process of both static and dynamic DNA origami nanostructures and their …

Managerial Entrenchment And Payout Policy: A Catering Effect, Daniel Gyimah, Ernest Gyapong

All Works

© 2020 Elsevier Inc. Agency theory suggests that entrenched managers are less likely to pay dividends. However, according to the catering theory, external pressures from investors can force managers to increase dividend payments. Hence, we test whether entrenched managers respond to investor demand for dividends and share repurchases. Using a large sample of 9677 US firms over the period 1990–2016 (i.e. a total of 80,478 firm-year observations), we test and find evidence that managerial entrenchment negatively impacts dividend payments. Our findings suggest that catering effects weaken the negative impact of managerial entrenchment on payout policy and that in firms with …

Common Raven Nesting And Spatial Distancing On Power Lines In Southeast Idaho, Usa, Quinn R. Shurtliff, Jericho C. Whiting

Human–Wildlife Interactions

Common raven (Corvus corax; raven) abundance and distribution have increased in western North America in recent decades, facilitated by anthropogenic subsidies and other environmental changes. Electrical power transmission line structures provide nesting substrates for ravens. When these structures transect landscapes where natural nest substrates are limited, they may facilitate raven predation on eggs and juveniles of sensitive avian and reptile species. Little information is available regarding raven nest density trends on adjacent power lines or how raven territorial behavior influences spatial partitioning of nests, and hence, nest density. This knowledge would be valuable for managers of sensitive prey …

Demography, Morphometrics, And Stomach Contents Of Common Ravens Examined As A Result Of Controlled Take, Corinne M. Gibble, Kriss K. Neuman, Jessie Beck

Human–Wildlife Interactions

Common ravens (Corvus corax; ravens) are known nest predators that have the ability to negatively impact nesting birds, including imperiled species of seabirds and shorebirds. We conducted systematic necropsies of ravens that were lethally controlled in Monterey Bay, California, USA during 2013–2015, in or near western snowy plover (Charadrius nivosus nivosus) nesting areas, in an effort to better understand body condition, overall health, and diet of individual ravens. Raven predation of snowy plover nests has increased over the years in the Monterey Bay study area, and lethal removal of ravens has been employed to reduce predation. …

Efficacy Of Manipulating Reproduction Of Common Ravens To Conserve Sensitive Prey Species: Three Case Studies, Corina A. Sanchez, Brianne E. Brussee, Peter S. Coates, Kerry L. Holcomb, Seth M. Harju, Timothy A. Shields, Mercy Vaughn, Brian G. Prochazka, Steven R. Mathews, Steffen Cornell, Chad V. Olson, David J. Delehanty

Human–Wildlife Interactions

Expansion of human enterprise across western North America has resulted in an increase in availability of anthropogenic resource subsidies for generalist species. This has led to increases in generalists’ population numbers across landscapes that were previously less suitable for their current demographic rates. Of particular concern are growing populations of common ravens (Corvus corax; ravens), because predation by ravens is linked to population declines of sensitive species. Ecosystem managers seek management options for mitigating the adverse effects of raven predation where unsustainable predator–prey conflicts exist. We present 3 case studies examining how manipulating reproductive success of ravens influences …

Explicit Tight Frames For Simulating A New System Of Fractional Nonlinear Partial Differential Equation Model Of Alzheimer Disease, Mutaz Mohammad, Alexander Trounev

All Works

This paper is devoted to develop a new mathematical model for Alzheimer disease based on a system of fractional-order partial differential equations. The system of Alzheimer disease includes neurons, astrocytes, microglias and peripheral macrophages, as well as amyloid β aggregation and hyperphosphorylated tau proteins. We consider the Caputo fractional derivative definition to analyze the formulated system by simulating the effect of drugs that either failed or currently in clinical trials. To simulate the model, we use tight frame (framelet) systems generated using the unitaryand oblique extension principle. According to the simulation results, and based on using such new direction of …

Files Cryptography Based On One-Time Pad Algorithm, Ahmad Mohamad Al-Smadi, Ahmad Al-Smadi, Roba Mahmoud Ali Aloglah, Nisrein Abu-Darwish, Ahed Abugabah

All Works

The Vernam-cipher is known as a one-time pad of algorithm that is an unbreakable algorithm because it uses a typically random key equal to the length of data to be coded, and a component of the text is encrypted with an element of the encryption key. In this paper, we propose a novel technique to overcome the obstacles that hinder the use of the Vernam algorithm. First, the Vernam and advance encryption standard AES algorithms are used to encrypt the data as well as to hide the encryption key; Second, a password is placed on the file because of the …

Use Of Factors In Development Estimates: Improving The Cost Analysis Toolkit, Matthew R. Markman, Jonathan D. Ritschel, Edward D. White

Faculty Publications

Factor Estimating is a technique commonly used by defense acquisition analysts to develop cost estimations. However, previous studies developing factors for the Engineering and Manufacturing Development (EMD) phase of the life cycle are limited. This research expands the current toolkit for cost analysts by developing cost factors in previously unexplored areas. More specifically, over 400 cost reports are utilized to create new standard cost factors that are delineated by five categories: commodity type, contract type, contractor type, development type, and Service. The factors are developed for those elements that are common in a wide array of projects such as program …

Modulation Of The Hyperfine Coupling In A Tbpc2 Single-Molecule Magnet With Electric Fields, David Fehr

Theses and Dissertations

In theory, a quantum computer can do everything a classical computer can do, and more. This is possible because of the principal difference between their respective fundamental units of computation. Classical computers use bits that can take on values of 0 or 1, but quantum computers use quantum bits, called qubits, that can take on values of 0, 1, or any combination of 0 and 1 by exploiting the rules of quantum mechanics. However, this quantum nature is extremely fragile and therefore it is imperative that qubits are protected from their environment. Conversely, qubits cannot be so isolated that their …

Graduate Student Theses, Dissertations, & Professional Papers

The following exploration of National Alcohol Prohibition in the United States employs an interdisciplinary approach to understand the impetus of the large-scale defiance of liquor laws and to identify the physical manifestations of the social process of mass resistance in the archaeological record. Historical documentation, newspaper publications, oral histories, landscape analysis of road development in Montana, and an archaeological survey of a mountain homestead site where manufacturer of illicit alcohol took place are used to contextualize the Prohibition Era from the perspective of the offender. The research goals of this work are varied and include documentation of the archaeological footprint …

Disabling Injustice In The Higher Education Classroom, Daniel W. Eadens, Danielle M. Eadens, Christopher Lanterman

Faculty Scholarship and Creative Works

This chapter explores perspectives in higher education classrooms, specifically the need for social justice in education through inclusive and universal design/ universal design for learning (UD/UDL). The authors contacted colleagues regarding what worked to change paradigms and perspectives around issues of social justice and advocacy in classrooms. Three themes emerged, mirroring those of the literature reviewed: scholarly strategies, structured activities, and amplifying marginalized voices. The authors also discuss how accessible and inclusive approaches disable injustice and ableism in higher education classrooms by recognizing disability as an element of diversity and the need for inclusive approaches on college campuses and beyond. …

Delegation, Administration, And Improvisation, Kevin Arlyck

Georgetown Law Faculty Publications and Other Works

Nondelegation originalism is having its moment. Recent Supreme Court opinions suggest that a majority of justices may be prepared to impose strict constitutional limits on Congress’s power to delegate policymaking authority to the executive branch. In response, scholars have scoured the historical record for evidence affirming or refuting a more stringent version of nondelegation than current Supreme Court doctrine demands. Though the debate ranges widely, sharp disputes have arisen over whether a series of apparently broad Founding-era delegations defeat originalist arguments in favor of a more stringent modern doctrine. Proponents—whom I call “nondelegationists”—argue that these historical delegations can all be …

Complicity And Lesser Evils: A Tale Of Two Lawyers, David Luban

Georgetown Law Faculty Publications and Other Works

Government lawyers and other public officials sometimes face an excruciating moral dilemma: to stay on the job or to quit, when the government is one they find morally abhorrent. Staying may make them complicit in evil policies; it also runs the danger of inuring them to wrongdoing, just as their presence on the job helps inure others. At the same time, staying may be their only opportunity to mitigate those policies – to make evils into lesser evils – and to uphold the rule of law when it is under assault. This Article explores that dilemma in a stark form: …

Federal Courts: Art. Iii(1), Art. I(8), Art. Iv(3)(2), Art. Ii(2)/I(8)(3), And Art. Ii(1) Adjudication, Laura K. Donohue, Jeremy M. Mccabe

Georgetown Law Faculty Publications and Other Works

The distinction among the several types of federal courts in the United States has gone almost unremarked in the academic literature. Instead, attention focuses on Article III “constitutional” courts with occasional discussion of how they differ from what are referred to as “non-constitutional” or “legislative” courts. At best, these labels are misleading: all federal courts have a constitutional locus, and most, but not all, federal courts are brought into being via legislation. The binary approach further ignores the full range of federal courts, which are rooted in different constitutional provisions: Art. III(1), Art. I(8); Art. IV(3); Art. II(2)/I(8)(3); and Art. …

Trade, Economy, And Work: A Shared Agenda For A Stronger Economic Future, Alvaro Santos, Christopher Wilson

The economies of the United States and Mexico have become inextricably linked. For both countries, the other is their top trading partner, with an annual value of $616.38 billion in 2019. Beyond cross-border trade, however, our global competitiveness is linked due to the depth of manufacturing integration. As a result, job creation and export growth are largely regional enterprises. Well over a billion dollars in commerce crosses the border each day, and the GDP of the six Mexican and four U.S. border states is larger than the GDP of all but the three largest countries in the world.

Bivens And The Ancien Régime, Carlos Manuel Vázquez

Georgetown Law Faculty Publications and Other Works

In its most recent decision narrowly construing Bivens v. Six Unknown Named Agents of Federal Bureau of Narcotics, the Supreme Court derided Bivens as the product of an “‘ancien regime,’ ... [in which] the Court assumed it to be a proper judicial function to ‘provide such remedies as are necessary to make effective’ a statute’s purpose.” This Essay considers the relevance for Bivens claims of the Court’s shift to a nouveau régime to address the implication of private rights of action under statutes. It first describes and assesses the Court’s reasons for shifting to the nouveau r …

The Evolution And Jurisprudence Of The Foreign Intelligence Surveillance Court And Foreign Intelligence Surveillance Court Of Review, Laura K. Donohue

Georgetown Law Faculty Publications and Other Works

The past eight years have witnessed an explosion in the number of publicly-available opinions and orders issued by the Foreign Intelligence Surveillance Court and Foreign Intelligence Surveillance Court of Review. From only six opinions in the public domain 1978–2012, by early 2021, eighty-eight opinions had been released. The sharp departure is even more pronounced in relation to orders: from only one order declassified during 1978–2012, since 2013, 288 have been formally released. These documents highlight how the courts’s roles have evolved since 2004 and reveal four key areas that dominate the courts’ jurisprudence: its position as a specialized, Article III …

Hannah Arendt Meets Qanon: Conspiracy, Ideology, And The Collapse Of Common Sense, David Luban

Georgetown Law Faculty Publications and Other Works

A June 2020 survey found one in four Americans agreeing that “powerful people intentionally planned the coronavirus outbreak.” In fall 2020, seven percent said they believe the elaborate and grotesque mythology of QAnon; another eleven percent were unsure whether they believe it. November and December 2020 found tens of millions of Americans believing in election-theft plots that would require superhuman levels of coordination and secrecy among dozens, perhaps hundreds, of otherwise-unconnected and unidentified miscreants.

Conspiracy theories are nothing new, and they raise a question that preoccupied Hannah Arendt in The Origins of Totalitarianism: whatever happened to common sense? Arendt …

The Case For Chevron Deference To Immigration Adjudications, Patrick J. Glen

Georgetown Law Faculty Publications and Other Works

Chevron skepticism is in vogue in legal academia, as Professors Shoba Wadhia and Christopher Walker’s recent entry in the genre demonstrates. They place their project within the broader academic trend of arguing for limitations on the application of deference to various administrative decisions, but their aim is ultimately narrower—to show that “this case against Chevron has * * * its greatest force when it comes to immigration.”

The Professors are incorrect. Immigration adjudication presents one of the strongest cases for deference to administrative adjudication. This case is founded in the text of the statute itself and its myriad general and …

In Search Of Equality For Women: From Suffrage To Civil Rights, Nan D. Hunter

Georgetown Law Faculty Publications and Other Works

This article analyzes women’s rights advocacy and its impact on the meanings of gender equality during the period from the achievement of suffrage in 1920 until the 1964 Civil Rights Act. It teaches that one cannot separate the conceptualization of equality or the jurisprudential philosophy underlying it from the dynamics and characteristics of the social movements that actively give it life. Social movements identify the institutions and practices that will be challenged, decisions that in turn determine which doctrinal issues will provide the raw material for jurisgenerative change. Without understanding a movement’s strategy and opportunities for action, one cannot know …
