Trudging off early on a Saturday morning to attend an engineering seminar may not be first on your "most favorite" things to do. But, the satisfaction of discovering something new is well worth the effort. Our group was small (22), but enthusiasm was high. Most who attended have attended our past seminars. This seminar was #5. Also, earning the four PDH’s for the morning is a side benefit—it should not be considered the main incentive. All topics covered were interesting and that alone should motivate us to explore these subjects thoroughly.
First to present was Bruce Weiss from Rockwell Automation. The topic—Geometric Dimensioning and Tolerancing. Bruce is an ASME certified Technologist (GDTP)—one of 300 in the world. Bruce is definitely an expert which was evident from his clear illustrations and knowledge of how to use the many symbols. He explained the importance of the system and how part yield and efficiency can be improved.
Dr. Maruthi Devarakonda was next. The topic--Energy Efficient Emission Control to Reduce the Impact of Global Warming. Maruthi covered the effect of emissions on our health and the first regulations legislated by congress in 1963 and amended in 1970, 1977 and 1990. The regulations resulted in a drop of CO concentrations since 1990 of 77%. He then went on to describe the different types of emission control devices as well as catalysts.
Dr. Todd Parrish from Northwestern University spoke on the Fundamentals and Applications of Neuroimaging methods. First he covered early methods of imaging to include X-rays and the CT scans which provided the first digital imaging. He went on to explain how MRI scans and the variation in magnetic fields creates an image. In addition, he showed how a stimulus to a specific region of the brain causes electrical activity and a corresponding change in blood flow. Dr. Parrish has studied the brain of a convicted serial killer in an attempt to explain his behavior (under tight security). A very interesting presentation.
Dr. Subha Kumpaty and two of his graduate students presented the final portion of our seminar. Operating under a grant from the National Science Foundation, the research goals were to determine optimum levels of molybdenum and the scan rates for laser metal deposition. Properties on the resulting samples to include hardness and corrosion resistance were studied. The advantages of utilizing molybdenum as a surface modification to a titanium/aluminum hip implant results in a harder surface and less corrosion in the human body. Thank you to Dr. Kumpaty and students Beth Paoli and Arianna Ziemer for the excellent presentation.
All of our presenters received a copy of Tom Fehring's recently released book, "The Magnificent Machines of Milwaukee", as well as a certificate of appreciation. Thanks to those on our board who were involved in the planning of this event and especially to Dr. Subha Kumpaty who has organized all of our technical seminars.
