Some Attributes of Huskies

Published November 19, 2019

Here is a picture of Echo, after recovering from her poisoning, at the cabin.

At Michigan Tech, our mascot is the Husky. I have a lot of fun with this, because Echo, one of our two family dogs, is a Husky. So I have learned a lot about this breed of dog from our Echo.

I want to call out five basic attributes that I associate with Huskies.

First of all, Huskies are very clever dogs. For example, Echo knows the name of many of her toys. Her favorite toys make noises—right now, the special favorite is a stuffed Woody Woodpecker—who makes the most ridiculous noise. So I can ask Echo, “Where’s, ‘whoo-hoo-hoo-ha-ha,’ and she knows exactly what toy to bring me.

Also, Huskies are very careful dogs—most of the time. Echo is really careful to sniff each treat I offer her, before eating it. Even though she knows it’s the same dog biscuit that she had yesterday, well—she has to sniff it every time. Which is why I was so surprised when one night earlier this year, as I was staying one night at what was soon to become our family cabin (out near Point Abbaye, Michigan), I heard her crunching on something. I went to investigate—and I couldn’t believe it. She was eating rat poison which I didn’t realize was there. It had been left in a hidden corner on the kitchen floor! Luckily, it was the kind of rat poison that has an antidote (massive doses of vitamin K).

And—Huskies are VERY VOCAL and musical dogs. I believe Echo speaks entire sentences. She can clearly communicate when she is hungry, when she wants to go out, if she is bored, if something is wrong, and more. And if we begin to howl (as much as any human can), she gets downright musical, joining in and sometimes harmonizing.

Finally, Huskies are incredibly playful dogs. Echo can play catch with herself. She tosses her toys up in the air, and then pounces on them as they come down. She plays dueling stick with our other dog, they run in tandem, each with their mouths on the stick as they bound down the trail, like a harnessed team of horses with a bit in their mouth. And more. Not really a fetching dog, Echo tends to set up more elaborate play-games.

That brings me to Husky Nation, Michigan Technological University—a place where you can be clever, careful, vocal, musical and playful!

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

Published November 15, 2019

By

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.”

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

Published October 28, 2019

By

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 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

Published October 23, 2019

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.
