Bearing Health Detector
Get PDFBearings, a common component in rotating machinery, are essential components of modern rotating machines; thus, monitoring their health is crucial when reducing downtime and boosting production efficiency. The Bearing Health Detector (BHD), a hand-held device, captures and processes the sound of a machine under test in real time and estimates the level of wear and tear by comparing the sound to previous tests. The BHD encompasses audiences involved with roller bearings in rotating machinery and is designed to provide the diagnosis of wear through the universal detection of good, satisfactory, and very poor with the following color scheme: green, yellow, and red. The device offers a near real-time response rate within proximity of the machinery with a high accuracy of 90% in bearing health estimation. Furthermore, simple labeled button features signify when to start collecting data. This device will lower the long-term cost of owning machinery with bearings because device operation does not require a professional technical background and gives an insight into when to replace bearings, rather than seeking professional consultation
Analytical Methods for Determining Connectivity Leakage in Collaboration With Meissner Filtration Products
Get PDFThe scope of our project involved choosing existing testing procedures and determining a viable sample size to determine an accurate leakage rate of single-use system connections (SUS). Another goal was to assess the effects of gamma irradiation on the material integrity of the hose barb to tubing connections.
Our key customer requirements included: being able to determine an overall leakage rate and making a repeatable testing process. The importance of these requirements was determined through our house of quality and Pugh charts. To achieve the requirements, we tested the leakage in low-pressure and high-pressure scenarios with a large enough sample size to meet the requirements of the central limit theorem (n=30), in order to get an accurate estimate. For a repeatable testing process, there was nothing to be changed with the hydrostatic burst test since it already included calibrated machinery and a strict SOP the operator must follow. On the flip side, Meissner’s SOP for the low-pressure gas test was vague and unclear on instructions to “manipulate” the testing sample. We decided to define “manipulation” of the sample to strictly apply the 90-degree bend, 90-degree twist, pulling in a straight line, and holding the middle and end of the tube (opposite sides of the connection). Additionally, we implemented the alternation between operators to minimize or eliminate operator bias. For specifications we looked into decreasing the observation time for testing for the low-pressure gas test. The modifications were finalized to delegating at least 2 personnel to operate the testing which reduces testing time, and the SOP was modified to shorten the waiting time from 2 minutes down to 1.5 minutes.
The result of our project was an improved SOP that made testing quicker and less susceptible to operator bias. Our testing performed with the modified SOP showed that there was no significant sign of operator bias. The data we gathered provided us with leakage rates for several hose barb connection configurations that we then compared to understand whether gamma-irradiation affects leakage. Our data indicates that gamma-irradiation negatively impacts the hose barb connection’s performance in terms of leakage and maximum allowable pressure
Teaching Reproductive Politics and Intersectional Empathy through Ethnographic Case Studies
Get PDFIn this critical commentary, I present feminist pedagogies developed over ten years of teaching “Cultural Politics of Reproduction” that scaffold students away from approaching reproductive experiences and politics through this register of polarization. This approach centers collaborative inquiry and critical reflection and uses ethnographic case studies to cultivate empathy. Such stance encourages students toward not only understanding that another person might make a decision that they fundamentally disagree with, but also the broader contexts shaping these decisions. Drawing on feminist scholarship focused on a range of cultural contexts, students learn to destabilize existing expectations and contrast how seemingly familiar politics take shape in unfamiliar communities. By identifying how racism, misogyny, and national politics etc. interact to shape the everyday politics of reproduction and examine how people make complicated decisions amidst stratified access, they become attuned to intersectionality in practice
Teaching Abortion as a Historical Construct: The Case of Early Twentieth-Century Brazil and Beyond
Get PDFUsing open-access primary sources available online, this activity teaches abortion as an unstable category through a specific case study, early twentieth-century Brazil. The one-week module, although specific to one geographic region and chronological period, can serve as a lesson plan for undergraduate history courses, for disciplines that use genealogy methods, and for interdisciplinary courses. The lesson plan helps undergraduates think critically about what we think we know about abortion, and how our current understandings are not fixed but rather contingent on the society in which we live and on who is practicing abortion. Changing understandings of what constitutes an abortion – from medical, legal, and moral standpoints – further influence who can access the procedure and who is penalized for doing so. Thus, the lesson employs an intersectional approach toward the history of abortion by emphasizing how changing knowledge affects the embodied histories of women in different ways
