Description
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.

Description
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.

Description
This research looks at a group of students from Tumaini Children's Home in Nyeri, Kenya. The purpose of this paper is to explore why this particular group of students is so academically successful. Quantitative research was taken from the average 2013 test scores of Tumaini students who took the Kenyan Certificate of Primary Education (KCPE) exam in comparison to the scores of students who are not residing in the orphanage. Qualitative research involves interviews from those students who live in Tumaini and interviews from adults who are closely connected to the orphanage. The purpose is to understand why the students are performing so well academically and what support they have created for themselves that allows them to do so.

Description
This thesis paper examines the rise of nationalist parties in the Netherlands from the 1960s to 2015. It examines two major explanations for this growth: increasing numbers of predominantly Islamic immigrants and the increasing powers of the European Union. Concerns with these events have brought neo-nationalist parties to the forefront of the political process. This analysis begins in the 1960s during the depillarization of Dutch society and concludes with Geert Wilders and the Partij voor de Vrijheid.

Description
This interdisciplinary thesis examines the possible relationship between the public speaking experience for women and the gender gap in political ambition. First, a historical analysis of women public speakers ranging from the 1800s to the Suffragettes to female politicians in the 1900s reveals a pattern of female public speakers in politics receiving extreme criticism for their communicative behavior. The thesis then turns to the socialization of young girls, highlighting how gameplay in children translates into gendered communicative behavior in adult women. Next, an examination of the pedagogy of public speaking showcases how the public speaking experience is different for women than it is for men, and how public speaking traditionally is taught in a masculine style. Then, through a review of the literature on the gender gap in political ambition, it is seen that not only are women severely underrepresented in political office in the United States, but women have far less political ambition than men. And a case study of the 2008 presidential primaries and elections, highlighting modern women in politics, demonstrates that the few women who are politically ambitious in the 21st century face criticism that mirrors those faced by political women decades and centuries prior. Finally, the thesis offers possible solutions to changing the experience of women as public speakers and fostering political ambition in women.

Description
The Latino population is the fastest growing minority group in the United States (U.S Census Bureau, 2003). Such a rapidly changing demographic stresses the importance of implementing strategies into the community social framework to accommodate for cultural and language differences. This research paper seeks to answer: what factors influence the sense of community among Latino families in Phoenix? The following questions will help to assess the dynamic relationship between sense of community and literacy 1) what is the perceived importance of literacy among Latino families living in Phoenix? 2) How is language development reflected among the family dynamics within a predominantly collectivist culture? It is hypothesized that both collectivism and literacy are the main influences on sense of community among this population.

The purpose of this research is to identify the factors contributing the resiliency of Syria's President Assad amongst a backdrop of falling authoritarians during the Arab Spring. After determining the Assad's regime's strategies of authoritarian rule both before and after the 2011 uprisings, this paper theorizes what Assad's persistence is most dependent on today by analyzing his discourse throughout the conflict. Assad's framing of the war to the media has significantly legitimized his rule.

Description
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.

Introduction/Purpose: This paper describes the process of the community needs assessment phase of program implementation for the Student Health Outreach for Wellness (SHOW) clinic. Homeless individuals are more likely (than non homeless individuals) to experience serious illness, depression and mental illness. Access to health care has been identified as a barrier to receiving appropriate health care to manage the diseases and conditions clients may have. SHOW's vision is to operate on Saturdays utilizing Health Care for the Homeless (HCH) to offer extended primary health care hours, along with offering health promotion programming to address the biopsychosocial components of their health. Ultimately, this aims to reduce the homeless population's need to visit emergency room departments for non- urgent, primary care visits. Methods: To validate the need for this clinic's operation of programming and health services, a community needs assessment was conducted to collect data about the population's current health status. Forty-three people (n=43) ages 20-76 (M = 44.87) were surveyed by a trained research team using interview questionnaires. Results: The results show a prevalence of self\u2014reported physical and behavioral conditions, and support that this population would benefit from extended hours of care. Mental and behavioral health conditions are the most prevalent conditions (with the highest rates of depression (41.86%) and anxiety disorder (32.56%)), followed by the common cold (23.36%) and back pain (16.28%). The average reported emergency department (ED) visits within the past six months was 1.18 times. Almost everyone surveyed would visit a free medical clinic on the Human Services Campus (HSC) staffed by health staff and health professional students on the weekends (93.18%). Conclusion: Overall, the community needs assessment conducted for SHOW supports the need for weekend access to health care facilities and an interest in health programming for this population.

Description
This paper examines the development of United States drone policy outside of traditional battle zones. It poses the question of why do states use drones as a projection of force? In particular, the paper examines the expansion of the drone program within a system of democratic checks and balances. It looks at the effect that political and legal influences have had on the expansion of the drone program and hypothesizes that the presence of these constraints should increase drone use outside of traditional battle zones. In order to investigate this hypothesis, the paper looks at data on drone strikes from Yemen and Somalia. The data partially supports the hypothesis as there has not been a clear linear increase in the number of drone strikes in each of these countries. Nevertheless, an examination of the surrounding literature regarding political and legal influences within these countries seems to favorably point to the increase of drone operations. Future research, however, needs to be cognizant of the limitations in gathering specific statistics on drone operations as these operations are covert. It's also important to understand how the covert nature of the drone operations impacts issues regarding political oversight and legality. Lastly, it's important to constantly examine the broader implications drone policy has for US policy.
