Girls Scouts Learn How to “Think Like an Engineer” at Michigan Tech

Girl Scouts gathered at Michigan Tech this week, to learn about electrical engineering from members of Michigan Tech’s student chapter of the Society of Women Engineers.

Saturday afternoon, nearly 90 Girl Scouts learned what it means to be an engineer. It came through trying and failing. Then trying again and failing. Then eventually, trying and succeeding. “Seeing that look on their face when they finally get something to work, that’s the most rewarding part of it — to see them say, ‘Yes, I did this. I can do it even though it was hard to do,’” said Zoe Wahr, outreach director for Michigan Tech’s Society of Women Engineers (SWE) chapter, which organized the event.  Read more about the event in the Daily Mining Gazette.

The Girl Scouts, from kindergartners through 10th grade, arrived at Michigan Tech from across the Upper Peninsula and Wisconsin. The event, called “Think like an engineer” encouraged attendees to think about careers in science, engineering, technology and math. Read more at TV6 Upper Michigan Source.

The scouts first enjoyed brunch at Michigan Tech’s Wadsworth Residence Hall before breaking out into activity groups by age. Kindergarten (Daisies); 2-3 grade (Brownies); 4-5 grade (Juniors); and 6-10 grade (Cadettes and Seniors). The younger groups made paper circuits,  “squishy” circuits made out of dough, and mini wiggling “bots.” Older students visited Blue Marble Security Enterprise headquarters in the EERC building, where they learned to solder holiday-themed LED circuit boards.

At the end of the activities, all of the students gathered for a Q&A panel of SWE members. The scouts also developed a”Take-Action Plan” based on all they learned in their workshops.

“We’re excited to be a partner and to share the fields of electrical and computer engineering with these bright young people,” said Liz Fujita, ECE academic advisor and outreach specialist, who helped coordinate the event.

“The vast majority were from out of the area – only 14 girls are from Houghton County,” said SWE faculty advisor Gretchen Hein, a senior lecturer in the Department of Engineering Fundamentals. “The furthest away is Green Bay, Wisconsin.”


Integrity Matters.

Five on a Treasure Island, by English author Enid Blyton, the first book in The Famous Five series.

Integrity matters. 

I learned about integrity from my parents, and from my teachers. I do remember a young-age incident, around first or second grade. My older sister and I broke into a locked room in our rented house (Olinbury House in Sussex, England) which held a treasure of books that we wanted to read. We knew we should not enter that room. However, we could see through the keyhole more books, in the very same enchanting series we loved. This was around 1968. Books still ruled the day—and we were already spending 100 percent of our allowance on books to read. So that was the temptation, more books. 

In the scullery, we noticed a set of keys that we tried against this locked room. In the bathtub, while reading this book, as my mother could not tear me away from it, somehow the truth came out.  Later that evening, I was punished a multiple factor more than I would have been, because of not being truthful about where I had “found” the book. My poor older sister was punished even more than me, “as she should have known better.” She was 9, and I was 7. 

I strongly remember another incident, in sixth grade. We were a set of students at different levels, all “learning” math (without actual instruction). I had fallen behind, and so I faked my homework, copying the answers from the back of the book. Mercifully, I was caught by the teacher, checking my work. I found this incident profoundly disturbing, and I remember feeling ashamed of myself. It was then, about age 11, that I fully realized it was my own decision what sort of integrity I would possess, across my life. In that moment, I believe, my character was set.

Fast forward. Throughout this past year, I’ve been in frequent correspondence with one of our engineering alumni. He lives in California and regularly sends me clippings from the LA Times concerning the admissions scandals at USC. While I do understand parents being concerned about their child’s education, I do not understand how a parent would compromise not only their own, but also their child’s integrity, out of a desire to have them be admitted to a university on a basis other than their own merit.

At Michigan Tech—of course, as you know—no one can earn a degree except through their own work. With this comes character. Along with character comes  confidence, courage, and conviction in the knowledge that with enough time and resourcesyou can do pretty much anything.

The picture below is from our Department of Mechanical Engineering’s senior dinner, where soon-to-be-graduates make an obligation to themselves to uphold the standards of the engineering profession, known as The Order of The Engineer.

Order of the Engineer ceremony, Department of Mechanical Engineering-Engineering Mechanics at Michigan Technological University.

That evening, in my first year as Dean of Engineering at Michigan Tech, I participated as well:

“As an Engineer, I, Janet Callahan, pledge to practice integrity and fair dealing, tolerance and respect; and to uphold devotion to the standards and the dignity of my profession, conscious always that my skill carries with it the obligation to serve humanity by making the best use of the Earth’s precious wealth. As an Engineer, I shall participate in none but honest enterprises. When needed, my skill and knowledge shall be given without reservation for the public good. In the performance of duty and in fidelity to my profession, I shall give my utmost.”

Now, if you’re interested in taking this oath (if you haven’t already) and you want to know more, please let me know—Callahan@mtu.edu.

Michigan Tech ECE welcomes Fulbright Scholar Koami Hayibo

Koami Hayibo, MS, a visiting Fulbright Scholar at Michigan Tech, from Energy Generation Academy in Lomé, Togo.

The Department of Electrical and Computer Engineering at Michigan Technological University welcomes Fulbright Scholar Koami Hayibo, from Togo, West Africa, population approximately 7.6 million.

While at Michigan Tech, Hayibo will study electrical engineering with a specialization in power systems. “I plan to focus on the production of energy through renewable energy sources,” he says.  “Togo is a small country in Africa and is only able to produce about 30% of its consumption of electricity. I became interested in this area because I suffered from this lack of electricity when I was in high school. I had to study for my high school degree using old-fashioned kerosene lamps and candles and that’s still the case for a lot of children living in the countryside. That’s why I am doing my best to help bring electricity to remote areas. And I hope my time at Michigan Tech will give me with skills to address this issue in a more effective way.”

Hayibo specializes in solar energy. He earned a Master’s in Engineering and a Master’s in Science both at Université de Ouagadougou in Burkina Faso. He came to Michigan Tech from Energy Generation Academy, based in Lomé, Maritime, Togo, where Hayibo serves as Technical Manager. Energy Generation is a pan-African organization that supports young Africans in addressing their generation’s most pressing challenges (in energy, agriculture, health) through entrepreneurship and technology. Its main guidelines are to provide basic electrification to every household in Africa, while empowering youth and offering them alternative employment perspectives, and also to provide a complete tracking of the innovative projects produced by African youth and ensuring  their success.

Michigan Tech has a record number of Fulbright Scholars on our campus this year, with a total of 17 students – 14 master’s and three PhD students, studying in 10 different programs.

The students are from Afghanistan, Egypt, Indonesia, Kazakhstan, Laos, Lesotho, Mauritius, Morocco, Pakistan, Russia, Serbia & Montenegro, Togo, and Ukraine. Such diversity in backgrounds and academic interests brings a richness to Tech and makes our Graduate School like no other.

The mission of the Fulbright Program is to increase international understanding and respond to critical global issues. It is funded and overseen by the State Department, with 155 countries participating in the Program. Fulbrighters exemplify the power of international academic exchange to transform lives, bridge geographic and cultural boundaries and promote a more peaceful and prosperous world.


Seismic Reflections: Siting the Gordie Howe Bridge

The Gordie Howe International Bridge connecting Windsor, Ontario, and Detroit, Michigan is currently under construction and expected to be complete in 2024 at a cost of $5.7 billion.  The bridge is named in recognition of the legendary hockey player, a Canadian who led the Detroit Red Wings to four Stanley Cup victories.

The construction of any large infrastructure project requires a strong foundation, especially one with the longest main span of any cable-stayed bridge in North America—namely, the Gordie Howe International Bridge over the Detroit River. More than a decade before ground was broken, careful siting of the bridge began to take place. By 2006 the list of possible crossings had been narrowed down to just two options.

Historical records from the early 1900s indicated that solution mining for salt had taken place on both sides of the river close to where the bridge was to be built. On the Michigan side, collapsed salt cavities caused sink holes located on nearby Grosse Isle. It was imperative that any salt cavities in the bridge construction area be found and avoided.

Seismologists Roger Turpening and Carol Asiala at Michigan Technological University

Seismologists Roger Turpening and Carol Asiala at Michigan Technological University were tasked by American and Canadian bridge contractors to select the best seismic method for searching for any cavities in the two proposed crossings—referred to at the time as “Crossing B” and “Crossing C”—and to interpret all resulting seismic images.

“Given the task to image a small target deep in the Earth, a seismologist will quickly ask two important questions: How small is ‘small?’ and How deep is ‘deep’? That’s because these two parameters conflict in seismic imaging,“ Turpening says.

“Seismic waves—vibrations of the Earth—are attenuated severely as they propagate through the Earth,” he explains. “Imaging small targets requires the use of high-frequency, seismic energy. When seismic sources and receivers are confined to the Earth’s surface, which is the usual case, waves must propagate downward through the Earth, reflect off of the target, and return to the surface. Soil, sand, and gravel in the surface layer overwhelmingly cause the greatest harm to image resolution, and the ray paths must pass through this zone twice.”

Turpening was one of the early developers of a technique called vertical seismic profiling, or VSP. “Seismic receivers are placed inside a vertical hole near the target. With the seismic source placed on the surface some distance from the hole, it’s possible to explore a region around the hole with ray paths that need to pass through the surface layer only once,” he says. “If the target is very important, we can drill a second hole and place the seismic source in it. Now we have even higher resolution because all of the ray paths are in the rock formations with low attenuation.”

The downside? “We can only make images of the region between the two holes. But if the target is extremely important in a limited area, we can use many boreholes and many images in the search. Given enough boreholes, a block of earth can be imaged with cross-well seismic reflection techniques.

A cross-well, seismic reflection image between test boreholes. The cavity is sharply seen because the shale stringers in the B-Salt (at the bottom of the image) are abruptly terminated. The cavity is approximately 375 ft. wide.

To site the Gordon Howie bridge, Turpening and Asiala chose a frequency band of 100Hz to 2 KHz—much higher than could be used with surface sources and surface receivers—for surveys on both sides of the river. This yielded high resolution seismic images, crucial for detecting cavities—and indeed they found one—on the Canadian side.

“The high-resolution imaging made it easy for us to spot missing shale stringers in the B-Salt layer in that image,” says Turpening. “This made the final selection of the bridge location simple. We found the cavity between boreholes X11-3 and X11-4, thus forcing the Canadians to chose Crossing B.  Obviously, the Michigan group had to, also, choose Crossing B.”

On the US side of the river geologist Jimmie Diehl, Michigan Tech professor emeritus, provided corroborating borehole gravity data.


Yooper Lights: Blue Marble Security Enterprise mentors 7th graders on an eCYBERMISSION

The Yooper Lights eCybermission team, L to R: Olivia Shank, Rebecca Lyons, Chloe Daniels, and Jenna Beaudoin

Students attending Lake Linden-Hubbell schools who live within one mile of their school are not eligible to take the school bus. Many walk to school, often in the dark, early morning hours. The same is true for students in another nearby school district, Calumet-Laurium-Keweenaw.

A small group of 7th grade students from Lake Linden-Hubbell High School in Michigan’s Upper Peninsula—Jenna Beaudoin, Chloe Daniels, Rebecca Lyons, and Olivia Shank—decided to do something to help improve safety for students who walk to school. Each was highly motivated, for personal reasons.

“I have three younger siblings who walk to school, and they aren’t always aware of their surroundings,” said Daniels.

“My uncle was biking one night and didn’t have a helmet or a reflector and he got hit by a car. He had brain trauma and now has trouble remembering certain things,” said Beaudoin.

“I want to be able to walk safely by myself or with my dogs in the early morning or in the evening when it gets dark,” said Shank.

“We live in a really snowy area, and kids can get hit,” said Lyons.

Helping kids and others walk safely in the dark is their mission, but it was more than that—it is their eCYBERMISSION, a national science competition sponsored by the Army Educational Outreach Program. Nationwide, students in grades 6-9 work in small teams for over a year to develop a process or product that will benefit their community. Locally, the Lake Linden Middle School eCYBERMISSION team is advised by Michigan Tech Engineering Fundamentals instructor Gretchen Hein, and chemical engineering senior Ryan Knoll.

Because none of them knew anything about circuits, the team contacted Glen Archer, interim chair of the Department of Electrical and Computer Engineering at Michigan Tech. Archer introduced the seventh graders to electrical engineering student John Robinault, outreach manager of Blue Marble Security.

Born out of the Michigan Tech Enterprise program, Blue Marble Security is a virtual company comprised undergraduate students focused on securing the future through thoughtful use of technology.

Twice a week, Beaudoin, Daniels, Lyons and Shank met with Robinault and computer science major Tyler Arthur in the Blue Marble Security lab, located in the EERC building on campus.

The girls modeled the casing of their LED reflector using Siemens NX software, created their circuit using National Instruments Multisim™ software, and modeled their circuitboard using Eagle PCB design software. They had never used the software or soldered. The Blue Marble students demonstrated how to model and solder, but the girls did the work.

Arthur was a brand new member of Blue Marble Security Enterprise when he began working with the girls. “It gave me an opportunity to teach some of the material that I was already familiar with, while also learning new things along the way,” he said. “We worked together to get familiar with CAD modeling, for instance.

In the process, Arthur learned a lot about working with younger students, something he hadn’t ever done. “The fact that the team members are all good friends made for an interesting group dynamic, because was easy for them to distract each other while working on the project.” Even so, the girls persevered. Throughout the fall, the team completed their research and designed their reflector. They took their preliminary design to their 7th grade science classes for feedback. Based on that, they updated the design, completed the circuit board and went back to the school for more feedback, this time visiting both 7th and 10th grade science classes, asking the students to compare their LED reflector to a plain reflector. After receiving more valuable feedback, the team modified their design.

At that point, they began testing their LED reflector—calling it the “Yooper Light”, and themselves, the Yooper Lights.

Outdoor testing was completed on a straight, flat road near their school, over a distance of 170 feet. Pedestrians (students grades 7-9), and drivers (students grades 10-12, plus college students and adults) were asked to report when they could see a person walking and wearing either the plain reflector or the Yooper light LED reflector.

Yooper Lights team tested their LED reflectors at night, with help from volunteers.

Due to weather conditions, only the college students and adults tested outside. The remaining tests were completed inside the school, in a dark hallway lit only by security lights. The Yooper Lights found that everyone could both see the LED reflector and the person wearing it over the entire testing distance.

They decided to conduct another, independent test to see just how far their LED reflector was visible. The maximum visibility was found to be 91.3 meters—over twice the previous testing distance.

Yooper Lights submitted their report to eCYBERMISSION, learning in March that they had made it to the virtual regional competition. Once again, Michigan Tech helped them out. The girls presented to judges at the Jackson Center for Teaching and Learning with help from Associate Director Jeff Toorangian.

In late April, Yooper Lights became the first place 7th grade team in Michigan—and a finalist in the North Central Region. In a word: Success! They were going to compete in Washington, DC at the national competition.

During the weeklong event in DC last June, the Yooper Lights team bonded with their eCYBERMISSION mentor, Michigan Tech alumna Sasha Teymorian, now a chemist in the US Army Research Laboratory. Teymorian graduated with her doctorate in Chemistry from Michigan Tech in 2015. Together they enjoyed a bevvy of cool activities, including one called “Houston, We Have a Problem,” that tasked the girls with engineering a solution to the Apollo 13 mission. They worked with radio-controlled cars and conducted ballistics on balloons, and even designed autonomous vehicles at the National Inventors Hall of Fame.

While in DC, Beaudoin, Daniels, Lyons and Shank also visited their Congressional representatives. They first met with Representative Jack Bergman, and then with Robert Curis, a staff member in Senator Debbie Stabenow’s office, sharing just how they used engineering to develop their LED light.

Finally, the Yooper lights presented their project to a team of eCybermission judges. “Although the team did not win the national competition, they gained a great deal from the experience,” said advisor Gretchen Hein.

What’s next for the team? Something they’re calling “Yooper Power”. Collaborating again with students from the Blue Marble Security Enterprise, as well as Michigan Tech student chapter of the Society of Women Engineers (SWE), the girls, now in 8th grade, will develop outreach activity kits for fifth and sixth graders. Their new mission: introduce more young students to the field of electrical and computer engineering.

Yooper Lights team member Olivia Shank models the casing of the LED reflector using Siemens NX software.
Chloe Daniels and Rebecca Lyons learn how to solder, with help from electrical engineering major John Robinault, a member of the Blue Marble Security Enterprise at Michigan Tech.
The team created two sizes and colors of 3D printed cases to test with their LED reflectors.
The Yooper Lights team used the Design Thinking process to develop their Yooper Lights. Design Thinking training is offered on campus through the Pavlis Honors College.
With more help from volunteers, the Yooper Lights team also tested their LED reflectors in a long, dimly lit hallway at Lake Linden-Hubbell High School.

 


Engineering Students Comment on Volunteer Work

Students make a difference by pulling weeds.Instead of sleeping in on a rainy Saturday, more than 500 Michigan Technological University students planted flowers, helped out at the Lake Superior Performance Rally and joined in on other projects as part of Tech’s 13th annual Make a Difference Day.

“I love having a day where I can give back with all of my fellow students,” said Amanda Moya, a fifth-year mechanical engineering student.

“I like to take advantage of the opportunity to give back and make a difference in the world,” said Blue Key member Jacob Allen, a third-year electrical engineering major.

Dr. Edmond O. Schweitzer III: An Inventor Who Helps Keep the Lights On—in 164 Countries Around the World

Michigan Technological University, at night.

Michigan Tech welcomes to campus today inventor Edmond O. Schweitzer III, recognized as a pioneer in digital protection. 

“Why shouldn’t we invent, and wake up every day wanting to go to work to find a better way to do something for other people?” says global innovator and inventor Dr. Edmond O Schweitzer, III, Chair, President and CEO of Schweitzer Electronics.

Dr. Schweitzer was recently inducted into the National Inventors Hall of Fame for inventing the first-ever digital protective relay. Digital protective relays detect electrical faults that cause power outages.

The first protective relays relied on coils and were electromagnetic. Schweitzer’s microprocessor-based digital protective relay is multifunctional, protecting power systems, recording data and detecting faults in lines more effectively. “His first revolutionary ‘relays’ came on the market in the 1980s,” said Bruce Mork, electrical engineering professor at Michigan Tech. “The design has led to reduced costs, flexible operation options and increased reliability. The product lines have been enhanced with many patents and with the utilization of today’s smart grid technologies.”

Schweitzer Electronics Laboratories, Inc. (SEL) based in Pullman, Washington is a longtime partner of Michigan Tech—supporting the Power System Protection Lab at Michigan Tech since 1993, and hiring at least 40 Michigan Tech ECE graduates over the years, plus a dozen more students thus far in 2019.

Inventing runs in Schweitzer’s family, and while on campus he will present a lecture on Creativity and Innovation at 4:15 pm in EERC 103. Wednesday’s lecture is open to the public. All are welcome to attend. Schweitzer will also join a roundtable of power companies to discuss Cybersecurity.

Todd Brassard, VP Operations of Calumet Electronics, arranged Dr. Schweitzer’s visit to Michigan Tech. Calumet Electronics Corporation is a key supplier-partner of printed circuit boards (PCBs) to SEL. The company, based in Calumet, Michigan, is an American manufacturer, supplying PCBs for applications demanding zero failures, zero downtime, and requires a lifetime of performance. Celebrating 50 years, Calumet is a critical supplier to mission critical industries including power grid management, , medical device, aerospace, industrial controls, and defense. Calumet is one of the few PCB manufactures who have made a commitment to American manufacturing.

At Michigan Tech, “SEL has supported us for years, incrementally donating lab equipment since 1993 when I started the protection course and lab here on campus,” adds Mork. “I became aware of their new technology and product lines while working as a substation design engineer in Kansas City in the mid-1980s. As a PhD student at North Dakota State University, I facilitated getting it into the labs there, and again at Michigan Tech after I arrived in 1992. I first met Ed when he presented a paper at the American Power Conference in 1993—it’s a paper I still use today when introducing microprocessor-based protection to my students.”

 


Stimulate Your Thought Processes: Meet Dr. Edmund O. Schweitzer, III at Michigan Tech This Week

“Why shouldn’t we invent, and wake up every day wanting to go to work to find a better way to do something for other people?” says global innovator and inventor Dr. Edmond O Schweitzer, III, Chair, President and CEO of Schweitzer Electronics.

Global Innovator Dr. Edmund O. Schweitzer, III, who comes from a family of inventors, will be on campus at Michigan Tech to deliver a lecture, “Creativity and Innovation,” this Wednesday, October 2 at 4:15PM in EERC 103. All are welcome. 

Dr. Schweitzer is recognized as a pioneer in digital protection and holds the grade of Fellow in the IEEE, a title bestowed on less than one percent of IEEE members. He received the IEEE 2012 Medal in Power Engineering, the highest award given by IEEE, for his leadership in revolutionizing the performance of electrical power systems with computer-based protection and control equipment.
Earlier this year, Schweitzer was inducted into the National Inventors Hall of Fame for his invention of the first microprocessor-based digital protective relay.  According to the NIHF, “Digital protective relays detect electrical faults that cause power outages. The first protective relays relied on coils and were electromagnetic. Schweitzer’s first microprocessor-based digital protective relay, the SEL 21, was multifunctional, protecting power systems, recording data and detecting faults in lines more effectively. His design has led to reduced costs, flexible operation options and increased reliability.”
He is the founder of Schweitzer Engineering Laboratories, Inc. (SEL) based in Pullman, Wash. The company invents, designs, and builds digital products and systems that protect power grids worldwide. SEL’s products also protect homes, hospitals and businesses in 163 countries around the world.
Dr. Schweitzer’s visit to campus is sponsored by Calumet Electronics Corporation, key supplier-partner to SEL of printed circuit boards. Their goal for the visit is to share ideas, advance innovative thinking, and build new bridges.
“SEL has supported the Power System Protection Lab here in the Department of Electrical and Computer Engineering at Michigan Tech since 1993,” said Professor Bruce Mork. “SEL employs at least 40 Michigan Tech ECE graduates, as well.”

Dean Kamen Visit Featured in Daily Mining Gazette

During his day-long visit to Michigan Tech last week to recruit engineering and computing students, inventor and innovator Dean Kamen also met younger students on FIRST Robotics teams from 18 middle and high schools across Michigan’s Upper Peninsula. Photo by Matt Monte, monte.net.

HOUGHTON — Dean Kamen is looking for his next engineers. Having already hired Michigan Technological University students, he knew where to look.

“I love their kids,” he said. “They’re smart, they’re focused, they’re mature, they’re earnest. And we want more.”

Kamen, president of DEKA Research and Development, visited Tech Thursday. He spoke to engineering students and met Upper Peninsula students participating in the FIRST Robotics program, which he co-founded.

“They’ve been great to us at FIRST, they’ve supported FIRST teams for a long time,” said Kamen, whose 440 patents include the Segway. “Now we can return the favor and start hiring some of their graduates and it’ll be a win-win. We want the kids, they want careers.”
