Buck converters are a class of switched-mode power converters often used to step down DC input voltages to a lower DC output voltage. These converters naturally produce a current and voltage ripple at their output due to their switching action. Traditional methods of reducing this ripple have involved adding large discrete inductors and capacitors to filter the ripple, but large discrete components cannot be integrated onto chips. As an alternative to using passive filtering components, this project investigates the use of active ripple cancellation to reduce the peak output ripple. Hysteretic controlled buck converters were chosen for their simplicity of design and fast transient response. The proposed cancellation circuits sense the output ripple of the buck converter and inject an equal ripple exactly out of phase with the sensed ripple. Both current-mode and voltage-mode feedback loops are simulated, and the effectiveness of each cancellation circuit is examined. Results show that integrated active ripple cancellation circuits offer a promising substitute for large discrete filters.

Historically, Supreme Court interpretations of the Constitution of the United States have been significantly important, impacting the lives of every American. This honors thesis seeks to understand the ways in which the Constitution has been interpreted through the lens of political ideology. Using constitutional theory, I explain how the political ideologies of classical liberalism, conservatism, libertarianism, and progressive liberalism have played a role in the interpretations of the First, Second, and Fourth Amendments. I also examine how these ideological interpretations have changed from 1776 to 2017, dividing the history of the United States into four eras: the Founding Era, the Civil War Era, the New Deal Era, and the Modern Era. First, the First Amendment's clauses on religion are examined, where I focus on the separation between church and state as well as the concepts of "establishment" and "free exercise." The First Amendment transitions from classically liberal, to conservative, to progressively liberal and classically liberal, to progressively liberal and libertarian. Next, we look at the Second Amendment's notions of a "militia" and the "right to keep and bear arms." The Second Amendment's interpretations begin classically liberal, then change to classically liberal and progressively liberal, to progressively liberal, to conservative. Finally, the analysis on the Fourth Amendment's "unreasonable searches and seizures" as well as "warrants" lends evidence to ideological interpretations. The Fourth Amendment, like the other two, starts classically liberal for two eras, then becomes libertarian, and finally ends libertarian and conservative. The implications of each of these conclusions are then discussed, with emphasis on public opinion in society during the era in question, the ways in which the ideologies in each era seem to build upon one another, the ideologies of the justices who wrote the opinions, and the ideology of the court.

It seems that we are incessantly scolded about the importance of the American political process and its virtue of practicality in contemporary society. Whether through the accumulation of the so-called facts about the issues that inform the veneration of the contest between candidates, the stern and noble duty of becoming an activist performing dreary tasks, or the religious fervor surrounding the sacred obligation of voting, we are assured and reassured that our system is sound and that we must only confront problems of implementation rather than structural ones. From here, the narrative goes that if we subscribe to the doctrine of exclusively employing the efficient, strictly rational, and the immediately realistic, we will almost assuredly succeed in persuading others toward producing the resolutions required to solve our shared challenges. Admittedly, these ideas serve a role in addressing the issues we face. However, when unaided by sophisticated and nuanced notions and applications of the fantastic, the beautiful, the ideal, the possible, the playful, the useless, in a word, dreaming, we foreclose the possibility of building a future that can qualitatively improve society and more meaningfully elevate our being-with-one-another in the world. Therefore, this work aims to validate the aforementioned claim by engaging in a critical, political, and hermeneutic exploration of what it means to dream against the backdrop of present-day American politics. It will honestly seek to analyze the prevailing notions of contemporary western thought and action to work on the way toward a new, yet latent, way of understanding. This understanding would fundamentally revolutionize the task of civilization as being grounded upon the appropriate channeling of our desires and dissatisfactions toward actualizing the projections of our imagination. Simply put, this project seeks to repudiate the mandate of work as toil and order as oppression to clear the way for envisioning a more suitable alternative.

In Arizona's early history, Females garnered more independence than most other women in the United States because they were forced to build a completely new life in settlements with little to no infrastructure. Now, Arizona has achieved a level of equality that no other state has yet to achieve in regard to gender representation. Yet, we have yet to achieve total equity. This paper looks to analyze responses that female senators from the Arizona State Legislature gave while being interviewed by the author. With questions derived from previous research conducted on women in politics at the state and federal level, this paper will delve into the personal experiences of six female senators. Although their personal narratives differ, their stories seem to reflect a collective tie that unites the female members together, beyond party allegiance. Each of the responses given by the senators had some aspects that showed trends supporting the majority of the hypotheses. Moving forward, in order to achieve 50% equality, two more senators would need to be elected and replace male senators.

This thesis examines the problems that occur when the politics and practices of social services, specifically maternal and prenatal care, are guided by a distorted understanding of immigration. It compares the politics and practice of this care across two international borders: the U.S.-Mexico and that within Hispaniola. In an ideal world, care would be extended to all individuals regardless of citizenship. However, since every welfare state has its limits at the national border, citizenship matters to both federal governments and medical professionals. Government-provided resources play an integral role in the current immigration debate, as these programs are a collective investment in which all individuals contribute in order to sustain it. The United States developed the welfare state in order to provide necessary resources to those who could not afford it. Its creators did not view these services as a handout, rather as a support for the future workforce of the country. However, health care was and still is not provided on this model of economic and social citizenship. Current U.S. healthcare policy dictates that no one can be turned away in an emergency situation because someone cannot pay their medical bill, including undocumented immigrants. But for immigrant mothers carrying children across the border, maternal and prenatal care does not qualify as an emergency and the federal government aid typically does not extend to them them as citizens. When care is extended to undocumented immigrants in the United States at all, it typically is provided to the child through Medicaid, who is by dint of the Fourteenth Amendment considered a citizen after birth. The relation between the Dominican Republic and Haiti offers a more complex situation, as the idea of birthright citizenship has recently been revoked. Following the Haitian Earthquake in 2010, the only healthcare to which many Haitians had access was across the Hispaniola border. Haitian women who give birth to children in the Dominican Republic are often not evaluated by a doctor until they are entering the delivery process, and even then health-care is complicated by or denied because of racial prejudice and unclear legal situation. In September of 2013, the Constitutional Court of the Dominican Republic issues a new ruling which declared that any immigrant born between 1929 and 2010 without documentation of their own or of their ancestors does not have citizenship, rendering many Haitians born in the Dominican Republic essentially stateless. To be born to a non-citizen mother typically means the child will likely be born with little or no prenatal care, and the mother will receive poor or inadequate care. Prenatal care is one of the most inexpensive elements of a care-model that carries huge returns relative to its costs. All governments would benefit from improved access to maternal and prenatal care because its future citizens who receive such care would be born healthier and have fewer expensive chronic illnesses. Fewer chronic illness among a population would have huge returns on the welfare state because fewer people would be utilizing it for expensive medical treatments. Though most medical professionals condemn the extreme act of denying care to pregnant women or infants (documented or not), the Dominican Republic and the United States have a popular politics that embraces this cruelty, despite the fact that both pride themselves on a multi-ethnic population. It is easy for policymakers to incriminate undocumented immigrants and claim that they are responsible for an illegitimate share of the consumption of the country's resources. Therefore, it seems likely that the host country's perceptions of immigrant natality and maternity help construct a negative image of the immigration "problem" in such a way that laws and policies are designed without accurate rationale. This thesis examines how the United States and the Dominican Republic might improve the relationship between the culture of healthcare and the role of the legal system for immigrants and their children. It seeks to understand the reasons, motivations, and consequences for denying immigrants services on the account of their citizenship status. The social, economic, and health consequences of being an undocumented citizen will be examined. Current legal policy and what political roadblocks and cultural prejudices must be overcome in order to implement a successful policy will be reviewed. Finally, the best practices prenatal care as a national investment will be discussed, as will the problem of cross-cultural perception of natality, maternity, and immigration.

This project was centered around designing a processor model (using the C programming language) based on the Coldfire computer architecture that will run on third party software known as Open Virtual Platforms. The end goal is to have a fully functional processor that can run Coldfire instructions and utilize peripheral devices in the same way as the hardware used in the embedded systems lab at ASU. This project would cut down the substantial amount of time students spend commuting to the lab. Having the processor directly at their disposal would also encourage them to spend more time outside of class learning the hardware and familiarizing themselves with development on an embedded micro-controller. The model will be accurate, fast and reliable. These aspects will be achieved through rigorous unit testing and use of the OVP platform which provides instruction accurate simulations at hundreds of MIPS (million instructions per second) for the specified model. The end product was able to accurately simulate a subset of the Coldfire instructions at very high rates.

ABSTRACT The First Ladies: Exploring Achievement and Public Perception Overview The First Lady has become a fixation of the American people and the press. This thesis examines how specifically this interest in the President's wife has evolved over time. Additionally, it explores a variety of factors that could possibly influence public perception \u2014 era, cultural norms, and advances in technology. Research Questions Does the era of the tenure of the First Lady affect public perception and press coverage of her? Do the cultural norms and values of the time of the First Lady's tenure affect public perception and press coverage of her? Do advances in technology affect public perception and press coverage of the First Lady? Goals The goal of this thesis is to examine how the press and the public interact with First Ladies of varying eras and political stances to determine how their image is shaped and disseminated in the news and to the public. Methodology This thesis explored these questions comparing materials from presidential libraries, academic journals, and news articles from sources such as The New York Times and Washington Post.

Although smaller and more local elections could have implications more dramatic to an individual than larger district-, state-, and nation-wide elections do, very few citizens vote in them. Moreover, citizens are limited in procuring further information on candidates, issues, and the overall election when there are fewer sources of such information across various mediums. While existing literature on political communication and voter participation does not yet extend far enough to sufficiently address the most local aspects of media effects on elections, the political science field’s dominating frameworks would suggest that an increase in news media, social media, and ground mobilization tactics would increase civic engagement and voter participation. My research, which focuses on hyperlocal elections, both supports a​nd​refutes certain elements of that suggestion. Based on surveys of potential voters in a university’s student government election and a school board election, interviews with two student government presidential candidates, and an analysis of social media engagement, my research compares three mass media platforms and two elections to characterize the effects of media on hyperlocal elections—that certain tactics have drastically different results on different populations. My research expands the body of media and politics knowledge to include hyperlocal elections, suggesting that civic engagement on the local levels require increased further study.

The world of a hearing impaired person is much different than that of somebody capable of discerning different frequencies and magnitudes of sound waves via their ears. This is especially true when hearing impaired people play video games. In most video games, surround sound is fed through some sort of digital output to headphones or speakers. Based on this information, the gamer can discern where a particular stimulus is coming from and whether or not that is a threat to their wellbeing within the virtual world. People with reliable hearing have a distinct advantage over hearing impaired people in the fact that they can gather information not just from what is in front of them, but from every angle relative to the way they're facing. The purpose of this project was to find a way to even the playing field, so that a person hard of hearing could also receive the sensory feedback that any other person would get while playing video games To do this, visual surround sound was created. This is a system that takes a surround sound input, and illuminates LEDs around the periphery of glasses based on the direction, frequency and amplitude of the audio wave. This provides the user with crucial information on the whereabouts of different elements within the game. In this paper, the research and development of Visual Surround Sound is discussed along with its viability in regards to a deaf person's ability to learn the technology, and decipher the visual cues.

This report was commissioned to provide an analysis and evaluation of consumer perceptions and branding as it relates to the political and social climate in America. To be able to do this, the paper analyzes shifts in the external environment as well as researching case studies and online consumer perception surveys. Overall, this paper aims to examine the distributed survey and attempt to correlate and identify how branding, consumer perceptions, and social and political issues all can work and affect one another. Through the administration of this survey, we were able to formulate a conclusion that points towards the importance of brands actively adhering to changing consumer preferences, ideals, and expectations.
