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.

Often equated with hospice or end-of-life care, palliative care is the expansion of traditional disease-model medical treatments to include the goals of enhancing quality of life, facilitating patient autonomy, and addressing physical or emotional suffering. This interdisciplinary model is essential throughout the cancer continuum and offers the best patient outcomes when initiated at the time of diagnosis. While extensive research exists on the purpose and benefits of palliative care, substantial barriers to early and effective implementation remain. This study aims to examine and integrate current research literature on oncology nurses' perceptions of palliative care, including comparison to evidence-based preferred practice. Synthesis of qualitative findings offers transformative reconceptualization aimed to inform nursing education and improve patient care.

Purpose: The purpose of this study is to examine perceptions of medical-surgical nurses of alcohol-abusing patients admitted to an acute care facility Background: Studies report that many nurses have negative feelings about substance-abusing patients (Neville & Roan, 2014). It has been found nurses report a lack of knowledge about substance abuse disorders, as well as a view that substance abusing patients are more emotionally challenging and dangerous, often leading to decreased motivation and lower levels of job satisfaction (van Boekel, Brouwers, van Weeghel & Garrestsen, 2013). However, studies have found that additional education can positively impact nurses' perceptions (Arthur, 2001). Methods/Approach: This study is a descriptive design using a 17-question 2-part survey. The first part of the survey includes seven demographic questions pertaining to the participants' characteristics and experiences. The second part of the survey is adapted from the Short Alcohol and Alcohol Problems Perception Questionnaire (SAAPPQ), a valid and reliable instrument used to assess healthcare providers' attitudes toward working with alcohol-abusing patients. Results: Eighty four medical-surgical nurses participated in the study. Over half reported having four hours or less of continuing education on alcohol abuse disorder. Regression analyses identified positive relationships between factors, particularly continuing education, on perceptions of alcohol-abusing patients. Conclusions/Implications: Results of this study can be used to determine what factors contribute to nurses' perceptions of alcohol-abusing patients in the medical-surgical unit, therefore aiding in identifying and developing effective policies, protocols, and interventions aimed at improving quality of patient care in this specific patient population.

The national average of children aged 19-35 months receiving all recommended vaccines was under 75 percent for the year 2014. In Arizona the average was 65.1 percent, ranking them as 46th in the nation. Language, availability and education are all barriers affecting the rates in Arizona. Appropriate education has the biggest impact on vaccination rates in Arizona. A review of resources available in Arizona was conducted and presented for parents of children in need of the vaccines. A poster designed to educate the population and promote vaccinations was created and distributed to the Maricopa County Department of Public Health and Mayo Clinic Hospital as well.

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 stigma associated with mental illness has been and continues to be a considerable issue of concern in the care of persons with mental illness. Stigma affects not only those with mental illness, but also their families, healthcare personnel, the social community, and policy formation. Common themes of stigma associated with mental illness are fear, social rejection, stereotyping, negative impact, and a lack of knowledge and awareness of mental illness. Despite a more accurate understanding of mental illness, stigma still exists. Interventions to help reverse the stigma associated with mental illness include education, awareness and an environment of inclusion. Toward this end, a PowerPoint presentation will be gifted to Arizona State University College of Nursing to be shown during the psychiatric mental health rotation outlining mental illness and stigma, and what nurses and future nurses can do to combat this stigma.

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.

In the United States, more than 22 million people are estimated to be affected by the chronic illness, asthma (American Lung Association [ALA], 2014). Of those 22 million, approximately 7.1 million are children (ALA, 2014). An important factor in trying to curb the frequency of asthma attacks is education. Particular elements of asthma education include symptom recognition, self-management skills, correct administration, and understanding how medications are used to control asthma. A review of the literature shows that multimedia education holds some promise in increasing asthma-knowledge retention. This creative project involved the creation of an asthma-education video with a concomitant asthma-education comic book. Of the two creations, the asthma-education video was used in a former Doctorate of Nursing Practice (DNP) student’s study to supplement a session at a clinic with an asthma educator. The tools included in the study, the Asthma Medication Use Questionnaire (Moya, 2014) and the Asthma Control TestTM (ACTTM; QualityMetric Incorporated, 2002), were completed by the participants prior to and after the implementation of the session that incorporated the video. The results suggested that the video had an effect on asthma control as measured by the ACTTM (QualityMetric Incorporated, 2002), but not on daily preventative asthma inhaler usage as measured by the Asthma Medication Use Questionnaire (Moya, 2014). The comic book has not been evaluated yet. Both multimedia education tools—the comic book and the video—were created as a requirement for the Barrett thesis.

Mentorship is important to learning because it provides a frame of reference and the guidance necessary to succeed for those who are inexperienced. The purpose of this study was to explore the impact of a one-semester mentorship program for freshman Barrett nursing students. Specifically, it was hypothesized that freshman Barrett nursing students (mentees) would experience higher levels of confidence as they enter their second year. With improved confidence and better preparation in handling stress, freshman Barrett students are more likely to stay in the Barrett program throughout their time at a university in the southwestern United States. The mentorship program included freshman Barrett students pursuing a degree in nursing as the mentees and Term 8 (senior) Barrett Nursing students as the mentors. The mentorship program supported freshman students in reaching out to their mentors for study tips, class advice, homework help, and use them as a general resource throughout the application process. Quantitative data was collected in a pre- and post-survey in order to analyze the confidence scores of mentors and mentees. The survey asked participants questions regarding their level of self-confidence and asked them to rank their responses on a Likert scale with 1 being strongly disagree and 5 being strongly agree. The results showed that confidence levels based on the quantitative data either stayed the same or was improved in every participant. Specifically, there were multiple statistically significant findings based on the paired t-tests that were run. Findings suggest the mentorship program improved the confidence levels in both freshman Barrett students and their Senior mentors.

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.
