Gpu Accelerated Algorithm For Large Weather Data Labeling, Sandip Sahani

Theses

In this thesis, we propose a GPU based approach to process large weather datasets. This work contributes to big data research with a parallel approach towards GPU architecture. A GPU-based algorithm is presented to perform 3D Connected Component Labeling algorithm in parallel. We successfully remove data-dependencies embedded between data frames to achieve pixel-level parallelism. Due the extremely large size of datasets, data frames cannot fit into GPU memory or CPU main memory and sometimes even on the hard drive. Frames have to be streamed through the memory hierarchy, partitioned and processed as batches, where each batch is large enought to …

Decision Making And Communication Process Assessment Of Nasa Using Three Change Requests From The Space Launch System Program, Karen Campbell Hicks

Theses

This thesis investigated the communication and decision making process as part of the Systems Engineering practices at the NASA/Marshall Center to determine its level of effectiveness. Data was collected across three change requests to assess how decisions were made, how the decisions were communicated, and whether a process mattered in the formulation and dissemination of those decisions. Data results revealed the comprehensive decision making process for the technical change requests to be effective. Evidence revealed that the process was sufficiently tailored to accommodate the need of each individual technical change which promoted effective communication amongst the stakeholders in the formulation …

Scholars Of Distinction And The Development Of Educational History In The United States, Karl M. Lorenz

Education Faculty Publications

The paper describes the accomplishments of a select number of distinguished scholars who advanced the cause of the history of education. The evolution of this field of study and inquiry followed its own unique path in the United States, and that at certain moments its trajectory was influenced by the thoughts and actions of celebrated professionals. Each individual contributed in a distinctive way, by either deepening or broadening the study of educational history in educator preparation programs, or by encouraging disciplined research and research-related activities in the area. In this latter endeavor, scholarship was often enhanced by making resources available …

Comte’S Positivist Doctrine And Reform Of Secondary Science Education In Nineteenth-Century Brazil, Karl M. Lorenz

Education Faculty Publications

This paper discusses the influence of the Positivist Philosophy on the teaching of science in the National Gymnasium, formerly the College Pedro II, in Brazil. With the proclamation of the Republic in 1889 and the subsequent educational reform of Minister Benjamin Constant in 1890, the curriculum of the college, and in particular the teaching of the sciences, was profoundly affected by the positivist ideas of Comte. An analysis of the programs of scientific studies adopted in the Gymnasium from 1890 to 1900 demonstrates that these were organized in accordance with the hierarchy of abstraction of human knowledge proposed by Comtean …

Discovering The Chinese Mining Child: The Archaeology Of Children And Childhood In Multicultural American Mining Communities, Nicole A. Lane

Graduate Student Theses, Dissertations, & Professional Papers

Children made up roughly one-quarter of the population of industrial boomtowns in the

North American West, underscoring the connections of family to places commonly

thought to be bachelor communities. By comparing artifacts and historical contexts from

three mining communities (Butte, Montana; Deadwood, South Dakota; and Sandpoint,

Idaho) established in the late 19th century, this thesis will contribute to archaeologies of

children, childhood, and socialization, examining material remains as a line of evidence

to study the ways in which relationships, gender, race, and class pervaded the lives of

children in these industrial settings. The methods employed here integrate information

from historical …

Microbubble Generation By Piezotransducer For Biological Studies, W. Zhu, M. Alkhazal, M. Cho, S. Xiao

Bioelectrics Publications

Bubbles induced by blast waves or shocks are speculated to be the major cause of damages in biological cells in mild traumatic brain injuries. Microbubble collapse was found to induce noticeable cell detachment from the cell substrate, changes in focal adhesion and biomechanics. To better understand the bubble mechanism, we would like to construct a system, which allows us to clearly differentiate the impact of bubbles from that of shocks. Such a generator needs to be low profile in order to place under a microscope. A piezoelectric transducer system was designed to meet the need. The system uses either a …

Indoor Location Tracking And Orientation Estimation Using A Particle Filter, Ins, And Rssi, Cameron Ramin Nouri

Master's Theses

With the advent of wireless sensor technologies becoming more and more common-place in wearable devices and smartphones, indoor localization is becoming a heavily researched topic. One such application for this topic is in the medical field where wireless sensor devices that are capable of monitoring patient vitals and giving accurate location estimations allow for a less intrusive environment for nursing home patients.

This project explores the usage of using received signal strength indication (RSSI) in conjunction with an inertial navigation system (INS) to provide location estimations without the use of GPS in a Particle Filter with a small development microcontroller …

Exclusion And Equality: How Exclusion From The Political Process Renders Religious Liberty Unequal, Philip A. Hamburger

Faculty Scholarship

Exclusion from the political process is a central question in American law. Thus far, however, it has not been recognized how religious Americans are excluded from the political process and what this means for religious equality.

Put simply, both administrative lawmaking and § 501 (c)(3) of the Internal Revenue Code substantially exclude religious Americans from the political process that produces laws. As a result, apparently equal laws are apt, in reality, to be unequal for religious Americans. Political exclusion threatens religious equality.

The primary practical conclusion concerns administrative law. It will be seen that this sort of "law" is made …

Anticipatory Remedies For Takings, Thomas W. Merrill

Faculty Scholarship

The Supreme Court has rendered two lines of decisions about the remedies available for a violation of the Takings Clause. One line holds that courts have no authority to enter anticipatory decrees in takings cases if the claimant can obtain compensation elsewhere. The other line, which includes three of the Court's most recent takings cases, results in the entry of an anticipatory decree about takings liability. This Essay argues that the second line is the correct one. Courts should be allowed to enter declaratory or other anticipatory judgments about takings liability, as long as they respect the limited nature of …

The Struggle For Administrative Legitimacy, Jeremy K. Kessler

Faculty Scholarship

Nearly forty years ago, Professor James 0. Freedman described the American administrative state as haunted by a "recurrent sense of crisis." "Each generation has tended to define the crisis in its own terms," and "each generation has fashioned solutions responsive to the problems it has perceived." Yet "a strong and persisting challenge to the basic legitimacy of the administrative process" always returns, in a new guise, to trouble the next generation. On this account, the American people remain perennially unconvinced that administrative decisionmaking is "appropriate, proper, and just," entitled to respect and obedience "by virtue of who made the decision" …

The Future Of Direct Finance: The Diverging Paths Of Peer-To-Peer Lending And Kickstarter, Kathryn Judge

Faculty Scholarship

For centuries, the trend has been toward longer and more complex intermediation chains in a wide array of contexts. The growing length and complexity of intermediation chains were both the by-products and drivers of ever-greater globalization and specialization. In recent years, however, there has been a shift in the opposite direction. In a variety of markets, suppliers and consumers increasingly transact directly with one another. Many of these developments have arisen from technological innovations that reduce search costs and other hurdles to transacting, like verifying information and negotiating the terms of a transaction. Airbnb, Etsy, and their kin, for example, …

The Inversion Of Rights And Power, Philip A. Hamburger

Faculty Scholarship

No constitutional test is more important than the compelling-government-interest test. It is the foundation of all analysis of constitutional rights. But can a government interest really defeat a constitutional right?

The courts repeatedly say that claims of constitutional rights must give way to government interests.The courts even sometimes say that a compelling government interest justifies the infringement of a right – as when the Supreme Court asks "whether some compelling state interest ... justifies the substantial infringement of appellant's First Amendment right." In support of such doctrine, it often is said that rights are "not absolute."

This sort of analysis …

A Conversation With Edie Windsor, Edie Windsor, Suzanne B. Goldberg, Madeline M. Gomez, Andrew Chesley

Faculty Scholarship

Suzanne Goldberg [SG]: It is not often that a law school gets to welcome a rock star. But in our world, Edie Windsor is a rock star. She is one of the major civil rights plaintiffs of our lifetime, whose lawsuit challenged – and triumphed over – the federal Defense of Marriage Act. Her victory in that suit has been vital to changing the landscape of marriage equality for all Americans. It is a tremendous honor, Edie, to have you here at Columbia Law School, and we welcome you.

Multidimensional Advocacy As Applied: Marriage Equality And Reproductive Rights, Suzanne B. Goldberg

Faculty Scholarship

Talking about marriage equality and reproductive rights advocacy together presents an interesting, and sometimes puzzling, assortment of challenges and opportunities. Both involve efforts to secure legal protections and social recognition that are fundamentally important to those who need them yet also deeply provocative to their opponents. For both, too, advocacy takes place on a shifting terrain shaped by competing views of sexuality, autonomy, equality, personhood, and more.

Yet the two advocacy efforts have experienced very different receptions over time. Just over two decades ago, the Supreme Court expressly affirmed that women have a constitutional right to seek an abortion and …

Appointments, Innovation, And The Judicial-Political Divide, Gillian E. Metzger

Faculty Scholarship

The federal appointments process is having its proverbial day in the sun. The appointment and removal of federal officers figured centrally in the Supreme Court's two major recent separation-of-powers decisions, Free Enterprise Fund v. Public Company Accounting Oversight Board and National Labor Relations Board v. Noel Canning. The appointments process has featured even more prominently in the political sphere, figuring in a number of congressional-presidential confrontations. Such simultaneous top billing in the judicial and political spheres is hardly coincidental. After all, it was President Obama's use of the Recess Appointments Clause in response to pro forma sessions that triggered …

Intermediary Influence, Kathryn Judge

Faculty Scholarship

Ronald Coase and others writing in his wake typically assume that institutional arrangements evolve to minimize transaction costs. This Article draws attention to a powerful, market-based force that operates contrary to that core assumption: Intermediary influence." The claim builds on three observations: (1) many transaction costs now take the form of fees paid to specialized intermediaries, (2) intermediaries prefer institutional arrangements that yield higher transaction fees, and (3) intermediaries are often well positioned to promote self-serving arrangements. As a result, high-fee institutional arrangements often remain entrenched even in the presence of more-efficient alternatives.

This Article uses numerous case studies from …

Two-Band Fast Hartley Transform, A. N. Skodras, Maurice F. Aburdene, A. K. Nandi

Faculty Journal Articles

Efficient algorithms have been developed over the past 30 years for computing the forward and inverse discrete Hartley transforms (DHTs). These are similar to the fast Fourier transform (FFT) algorithms for computing the discrete Fourier transform (DFT). Most of these methods seek to minimise the complexity of computations and/or the number of operations. A new approach for the computation of the radix-2 fast Hartley transform (FHT) is presented. The proposed algorithm, based on a two-band decomposition of the input data, possesses a very regular structure, avoids the input or out data shuffling, requires slightly less multiplications than the existing approaches, …

A Mechanism For Sensorimotor Translation In Singing: The Multi-Modal Imagery Association (Mmia) Model, Peter Q. Pfordresher, Andrea R. Halpern, Emma B. Greenspon

Faculty Journal Articles

WE PROPOSE A NEW FRAMEWORK TO UNDERSTAND singing accuracy, based on multi-modal imagery associations: the MMIA model. This model is based on recent data suggesting a link between auditory imagery and singing accuracy, evidence for a link between imagery and the functioning of internal models for sensorimotor associations, and the use of imagery in singing pedagogy. By this account, imagery involves automatic associations between different modalities, which in the present context comprise associations between pitch height and the regulation of vocal fold tension. Importantly, these associations are based on probabilistic relationships that may vary with respect to their precision and …

The Quixotic Quest For Fairness: The Sec's Role In The Rise Of High Frequency Trading, Jan Traflet, William R. Gruver

Faculty Journal Articles

This paper examines the complex factors facilitating the rise of high frequency trading (HFT) from a historical perspective. Over the course of several decades, various stock market regulations and reforms, championed by the Securities and Exchange Commission (SEC), created room for HFT to develop and flourish. While advancements in technology initially may appear to be the primary cause of HFT, in fact, HFT could not exist (or at least, not to the extent it does today) if certain rules and older ways of doing business on the exchanges were still in place, and if other regulations did not support its …

Natural Kindness, Matthew H. Slater

Faculty Journal Articles

Philosophers have long been interested in a series of interrelated questions about natural kinds. What are they? What role do they play in science and metaphysics? How do they contribute to our epistemic projects? What categories count as natural kinds? And so on. Owing, perhaps, to different starting points and emphases, we now have at hand a variety of conceptions of natural kinds—some apparently better suited than others to accom- modate a particular sort of inquiry. Even if coherent, this situation isn’t ideal. My goal in this article is to begin to articulate a more general account of ‘natural kind …

Death Penalty Drugs And The International Moral Marketplace, James Gibson, Corinna Barrett Lain

Law Faculty Publications

Across the country, executions have become increasingly problematic as states have found it more and more difficult to procure the drugs they need for lethal injection.At first blush, the drug shortage appears to be the result of pharmaceutical industry norms; companies that make drugs for healing (mostly in Europe) have refused to be merchants of death. But closer inspection reveals that European governments are the true change agents here. For decades, those governments have tried-and failed-to promote abolition of the death penalty through traditional instruments of international law. Turns out that the best way to export their abolitionist norms was …

Halliburton Ii: A Loser's History, Adam C. Pritchard

Articles

The Supreme Court was presented with an opportunity to bring fundamental reform to securities class actions last term in Halliburton Co. v. Erica P John Fund, Inc.. The Court ducked that opportunity, passing the buck to Congress to undo the mess that the Court had created a quarter century prior in Basic Inc. v. Levinson. Congress's history in dealing with securities class actions suggests that reform is unlikely to come from the legislature anytime soon. The Securities and Exchange Commission appears to be satisfied with the status quo as well. With these institutional actors resisting reform, corporations and …

The Challenge And Recusal Of Judges Of The International Court Of Justice, Chiara Giorgetti

Law Faculty Publications

The rules and mechanisms to challenge and recuse a judge of the International Court of Justice ("ICJ") are unique and pertain to the control mechanisms proper to permanent international dispute resolution bodies, characterized by a plurality of representative, elected judges. Indeed, the Statute of the ICJ ("Statute") provides a series of control mechanisms aimed at ensuring the independence and impartiality of its judges. The drafters of the Statute adopted a multi-tiered approach, relying first on self-control of each judge, and then envisaging a subsidiary control role for the President and the Court as a whole. Third-party requests for recusals are …

Marriage Equality Comes To America, Carl W. Tobias

Law Faculty Publications

Marriage equality is sweeping the nation. Four appeals courts recently affirmed district judges’ opinions which invalidated numerous state laws proscribing same-sex marriage. Yet, the Sixth Circuit reversed a number of district jurists, prompting a circuit split that provoked Supreme Court resolution. Because marriage equality’s status is unclear, this piece assesses disposition of the litigation and recommends how to clarify marriage equality.
