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.

Beginning in 2011, California’s most recent drought has brought four years of some of the warmest and driest seasons on record. Mendota, California in the San Joaquin Valley is a microcosm of the struggles many agriculture communities face when water resources are scarce. Known as the “cantaloupe capital of the world,” agriculture represents over half of Mendota’s economy, making unemployment one of the many challenges they face. However, community members are working to move forward and preserve the place they call home.
Medota has a population of about eleven thousand people with over 96 percent of them being Hispanic. The stories of elected officials, field workers, farmers, police, school leaders and local business owners give testament to a mounting fear for future water allocation. But their voices also give way to a shared belief—the community’s resilience will persevere through California’s drought. Mendota is presented through a multi-media piece that uses photos, videos and descriptive articles to showcase both their hardship and hope.

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.

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.

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.

Description
According to the United States Department of Agriculture, "food insecure homes" are households that are at times unable to acquire enough food to met the needs of their members. During the year 2010, this designation applied to roughly 14.5% of American households. In Arizona, the situation is even direr, with nearly 1 in 5 children falling into the range of food insecurity. These alarming statistics appear even graver in the light of the staggering amount of food that is wasted in America. In an attempt to combat both the problems of food insecurity and food waste, organizations have begun to focus their energy on "rescuing and repurposing food." In other words, these organization take prepared and perishable food from one location where it would go to waste, and redistribute it to places that it will be consumed, such as soup kitchens and shelters. The purpose of this thesis is to fully explore the successful workings of Waste Not, Inc. in Phoenix, AZ, and City Harvest in New York City, NY, and then make necessary critiques and draw implications for future food rescue programs.

Description
This thesis details our experience assisting BASE Equity Partners, a private equity firm based in New York City, on three prospective agricultural dealership deals over the course of this past academic year. The firm is currently structured as a Fundless Sponsor. This distinct structural trait is common for a type of private equity firm known among practitioners as pledge funds. This creates an interesting element for our experience as there is very limited academic research on these types of firms, which, since the Great Recession, have become popular players in middle-market private equity deals. We, first, provide some historical context on pledge funds and identify their primary differences with traditional private equity. The remainder of the paper documents our experience working on the agricultural dealership deals. We have organized this portion after the manner in which we received assignments. We go into detail on the specific projects with which we were tasked, our interactions with the partners and the major takeaways we had from this learning experience. This thesis paper will enrich the academic knowledge regarding pledge funds—and private equity generally—by documenting a real experience of what it is like performing analyst-level tasks at a real firm. Additionally, we were privy to information that is highly confidential, and though we have protected the confidentiality of the companies through pseudonyms and redaction of confidential material, all of the financial data shown, models provided and qualitative discussion is real.

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.

Parents in STEM careers are more apt to guide their kids towards STEM careers (Sherburne-Michigan, 2017). There are STEM programs and classes for students who are interested in related fields, but the conundrum is that students need to be interested in order to choose to participate. The goal of this creative project was to introduce engineering concepts in a high school class to reveal and investigate the ways in which engineering concepts can be successfully introduced to a larger student populace to increase interest in engineering programs, courses, and degrees. A lesson plan and corresponding materials - including circuit kits and a simulated ball launching station with graphical display - were made to accomplish this goal. Throughout the lesson students were asked to (1) use given materials to accomplish a goal, (2) predict outcomes based on conceptual understanding and mathematical calculations, (3) test predictions, (4) record data, and (5) analyze data to generate results. The students first created a simple circuit to understand the circuit components and learn general electrical engineering concepts. A simple light dimmer circuit let students demonstrate understanding of electrical concepts (e.g., voltage, current resistance) before using the circuit to a simulated motor in order to launch a ball. The students were then asked to predict the time and height of a ball launched with various settings of their control circuit. The students were able to test their theories with the simulated launcher test set up shown in Figure 25 and collect data to create a parabolic height versus time graph. Based on the measured graph, the students were able to record their results and compare calculated values to real-world measured values. The results of the study suggest ways to introduce students to engineering while developing hands-on concept modeling of projectile motion and circuit design in math classrooms. Additionally, this lesson identifies a rich topic for teachers and STEM education researchers to explore lesson plans with interdisciplinary connections to engineering. This report will include the inspiration for the product, related work, iterative design process, and the final design. This information will be followed by user feedback, a project reflection, and lessons learned. The report will conclude with a summary and a discussion of future work.
