Fridays with Fuhrmann: Michigan Tech’s Winter Wonderland

Published February 5, 2016

This week Michigan Tech is celebrating its annual Winter Carnival. The students have Thursday and Friday off from classes, and there are a lot of winter-related activities going on. The most visible sign of Winter Carnival for most of us is the collection of interesting and creative snow sculptures that have popped up all over campus. These attract a lot of visitors and media attention, and are a lot of fun.

Up to now I have used this column to write about electrical and computer engineering, and engineering education, but I thought this week it would be appropriate to take a break and write about something else that Michigan Tech is famous for: snow.

Michigan Tech is, according to AccuWeather.com and some other polls, the snowiest campus in the United States, with over 200 inches of the white stuff per year on average. Snow is definitely part of who we are, part of our heritage and culture. In a typical winter the snow starts up around Thanksgiving, gets pretty serious in December and January, then stretches into February and March, sometimes even into April. The city and the university are all geared up to handle the snow; they keep the roads plowed and haul the snow away to snow dumps out of town when necessary. All the residents of Houghton – most, anyway – have a plan to handle the snow in their driveways, sidewalks and lawns. We take it all in stride. To be honest, most of us are “snow snobs” laughing with derision at poor souls further south when a couple of inches brings a city to its knees.

200 inches of snow sounds like a lot – and I guess it is – but for the most part it is pretty benign. One can see major winter storms on the national news that dump one or two feet of snow all at once on some unfortunate region, and even though that can happen here too it’s actually pretty rare. The reason we get so much snow is in the first place is something called “lake effect”, in which cold Arctic air blows down out of Canada from the north and west, across Lake Superior, picking up moisture from the warmer water, forming snow in the air and then dumping it on the Upper Peninsula when it hits land. Lake effect snow doesn’t need inclement weather to happen; I have seen snow falling and the sun shining all at the same time. Of course, we can also get what is called “system snow”, meaning the same kind of winter storm systems that can happen anywhere in the upper Midwest. Our biggest events occur when both happen at the same time, something they call “lake effect enhanced snow.” My main point here is that you don’t need major blizzards to create 200 inches of snow in a year. You just need a little bit at a time, over an extended period of around 4 months, and as long as the temperatures remain cold it just piles up.

So what is all this snow good for? In a word, plenty. Houghton residents and Michigan Tech students know that the best way to deal with the snow is to get out and enjoy it. One of my favorite activities is skiing, both downhill and cross-country. (I’m not particularly good at it, but I don’t let that stop me). For downhill skiing, Michigan Tech has its own Mont Ripley, just across the Portage from Houghton. It’s not a huge hill, only 450 feet vertical, but what it lacks in size it makes up for in convenience. I have a season pass and can go on a moment’s notice. Don’t let the small size fool you, either: it has plenty of challenging runs. For the more adventurous skier, an hour away near Copper Harbor, is the cult favorite Mount Bohemia. This place is for expert skiers only (the trail map says “No Beginners Allowed” in bold letters) with 900 feet vertical and almost entirely black diamond runs, and none of it groomed. It includes 400 acres of glade skiing too with some of that rated as double and triple black diamond. With a bare minimum of amenities at the bottom, Bohemia is paradise for ski nuts. If cross-country skiing is your thing, there are four different trails systems right in the local area, including an extensive set of trails owned and operated by Michigan Tech. This is a world-class facility in every sense; Michigan Tech has played host to Olympic trials and just last month hosted the U.S. national cross-country championships. The conditions are usually great, the trails are well maintained, and the scenery is beautiful. My only complaint, as a “classic” or “glide” skier, is having to put up with those healthier-than-thou “skate” skiers as they go zipping past me in their garish spandex outfits!

There is plenty to do besides skiing of course. Snowshoeing is a favorite activity for many. For those who prefer their winter sports indoors, hockey is very popular and in fact there are a number of ECE faculty members who play in a local recreational league. The ECE Department puts on a student-faculty hockey game every December. They even got me out on the ice my first year in the department (just once.) For those who like motorized sports, snowmobiling is big around here too. You might think there would be tension between the “natural” outdoors types and the snowmobilers, but in my observation the two camps have reached a sort of peaceful coexistence. The snowmobiles have their own set of trails which are quite extensive, covering hundreds of miles of old railroad beds across the U.P. (one would NEVER mix skiing and snowmobiling on the same trail system.) It can be a little noisy sometimes, but you get used to it quickly, and most people recognize the economic benefit to the region. People come from all over to ride our snowmobile trails, and the years we do the best are the ones when we have snow when others don’t, like in Wisconsin, Illinois, and downstate Michigan. There is snowmobile parking on the Michigan Tech campus, and once you get past the novelty it seems perfectly ordinary.

So there you have it – Michigan Tech, in addition to all of its contributions in science, technology, engineering, and math, is a winter wonderland. This is a unique place to live, work, and play. Students and alumni reading this know exactly what I’m talking about. Everybody else, you are welcome to visit – we’d love to show it to you.

Fridays with Fuhrmann: Removing the barriers for women in electrical and computer engineering

Published January 29, 2016

By Lisa Hitch

This week we learned that Michigan Tech, along with the University of Michigan and Michigan State University, has been selected for a grant from the National Center for Women and Information Technology (NCWIT) Pacesetters program, sponsored by the National Science Foundation (NSF), Google and Qualcomm. The aim is to develop aggressive goals and plans to increase the participation of women in computing and information technology. Michigan Tech is pleased to be recognized for its efforts to bring more women into the field. I congratulate Linda Ott from the Department of Computer Science on her leadership in bringing the grant proposal process to a successful conclusion.

This is a good opportunity for me to offer a few informal thoughts about the issue of women in electrical and computer engineering and what we can do, and need to be doing better, to bring more women into the field. This has been a conundrum for the ECE Department for a long time. We are not alone in that struggle; it is a nationwide issue. The female undergraduate enrollment in the ECE Department has hovered below 10% for many years, although there has been a very slow rise and this past fall we were at 10.8%, a minor victory of sorts I suppose. Many of us in electrical engineering are left wondering why this has to be the case. We can jump up and down and stand on our heads and say what a great field this is, and talk about all the career opportunities in EE (and I believe that with all my heart) but still that message doesn’t seem to be getting across, or at least isn’t making an impact. I will be the first to admit that I say all those things as a 58-year-old male who has had a reasonably successful and rewarding career, and that it is hard for me to see things from the perspective of a young woman about to graduate from high school.

You hear a lot of things about where the disconnect might be. It could be our culture, especially our youth culture, in which girls form opinions about themselves in middle school and high school about ability in math and science, which have little basis in truth but which they carry for the rest of their lives. It could be the professional environmental in high-tech areas like Silicon Valley, notorious for its “brogramming” culture in certain parts of the start-up world. It could be the lack of role models, in colleges and universities where electrical engineering and computer science is taught, and in industrial settings that come after. It could be that women look into the working world and just don’t see a path forward in an environment that is so dominated by men. All of these arguments have merit, and we need to be vigilant and aggressive in removing the barriers that are implied in each of them.

One often hears the argument that women are not attracted to electrical engineering because it is not a field that is “helping” or “nurturing”. I am going to go out on a limb here and say that this is complete hogwash and I reject it completely. First of all, saying that all women want to be caregivers is just buying into the stereotypes that have kept them out of the field in the first place. Second, and more importantly, the idea that electrical engineering is not a “helping” field is flat-out ridiculous. I would argue that electrical engineers have done more to help humankind in the 20th century than any other professional group you can name. What is more “helping” than bringing electrical power to every home and office in the United States? What is more “helping” than creating a communication network that allows people to connect via voice, text, or video, halfway around the world, at the touch of a button? What is more “helping” than designing the technology and the systems that provide for our common defense, protecting the nation and keeping us all safe in our homes? What is more “helping” than creating the technology that brings us the aesthetic joy and pleasure of music, video, and cinema? If someone wants to make an argument in support of the medical profession, I suppose we could sit down and have a good debate, but the first thing I would point out, as I did in this column three weeks ago, is that EEs were major players in that arena too!

Now that I got that off my chest, I’ll conclude by mentioning some of the things we are doing in the ECE Department at Michigan Tech to attract more women into our ranks. The ECE Department participates in Michigan Tech’s ADVANCE initiative, an NSF-supported program designed to the hiring and retention of women faculty, thereby creating a professional environment that our students can view as a model for the industrial world. We have wonderful and creative outreach programs for middle and high school age girls, in our summer camps and during the academic year; this is led enthusiastically by our Associate Chair Glen Archer, with help from a great group of students in the Blue Marble Security Enterprise. Dr. Archer was also the ECE point of contact for the successful NCWIT proposal. We have created an ECE Women’s Center in the EERC, a space on the 7th floor where our female students can meet for academic and social interactions. We have instituted two new concentrations within the BSEE degree, in Biomedical Applications and in Environmental Applications, that have a secondary but explicit aim of attracting more women to the field. I can’t say that we have found the magic bullet yet that is going to boost our female enrollment to 20% or 30% or more, but we are giving it our best shot.

This is an issue for which there are probably as many opinions as people who think about it. On this, and any other issue for that matter, I am always open to hearing from others and having a discussion. If you have read this far and want to take it further, please feel free to get in touch.

Fridays with Fuhrmann – Teamwork without Borders

Published January 22, 2016

By Lisa Hitch

I am writing today from beautiful Boulder, Colorado, where I have been attending a research progress review on a project I have been working on, along with other Michigan Tech faculty and students. The project is sponsored by Google. Michigan Tech is fortunate to be a research partner with Google on something they call a Multi-University Research Agreement, or MURA. I can’t tell you the technical details of what we are doing, yet, but later this year everything will be made public.

Having observed how this project is managed over the past year, I am struck by how much the workplace, the team organizations, and the expectations of engineers have changed over the years. This has been a great experience for me, not only because the work is interesting but because it gives me a glimpse of what our graduates can expect as they enter the workforce.

One of the most remarkable things I have noticed is how collaboration tools have made the world a smaller place, and have made geographical differences practically irrelevant. The team working on this project, about 30 people all together, comprises full-time Google employees, independent contractors, engineering companies, and university teams like ours from Michigan Tech. The group is spread out from Hawaii, to California, to Michigan, and to Europe. Subsets of the team meet regularly via Google Hangout, which is a pretty easy-to-use teleconferencing tool, and it is like being in the same room (there is the one remaining issue of time zones, but most people don’t have a big problem with it.) Even when most of the group gets together in the same city, like this week, there are still those who call in and contribute.

The success or failure of this project (and I’m pretty sure it’s going to be successful) depends on the ability of all the participants to work together as a team. This week we had discussions about how things went in 2015, and the overall consensus was that the teamwork was pretty good. It reminds me of why it is so important for us at Michigan Tech to teach our students about teamwork in our capstone projects, whether in Senior Design or Enterprise. They are going to be working on teams when they leave the university, and knowing how to collaborate, how to get along, how to get work done on time, how to communicate, how to make expectations clear for others – these are all things that are going to be critical skills for career success. The other side of teamwork that we stress at Michigan Tech is the development of individual skills. Everyone on this Google project has a seat at the table because they are really good at what they do, and I don’t imagine that’s going to be any different anywhere else.

Finally, I will mention that the nature of engineering careers is changing rapidly. Certainly there will be those that work full-time for a large corporation, and maybe they stay with that corporation a long time. On the other hand, there are those that work for corporations, but change jobs often. Others work as independent contractors, coming and going from teams as their skills are needed. I am fascinated by these engineers, at least the ones I have seen in this group: they are extraordinarily talented in their particular area of expertise, and because of all the collaboration tools available today they can live wherever they want. In all of these cases I am just talking about engineers selling their time and expertise; I haven’t begun to talk about entrepreneurship, which is another avenue that engineers are increasingly exploring. The bottom line is, if an engineer is good at what he or she does, their career arc and their lifestyle is limited only by the imagination.

At Michigan Tech we do our best to prepare students for this new engineering environment of the 21st century. I am always open to feedback about how well we are doing.

Being able to travel to meetings like this has its perks. On Friday, when this is posted, I’ll be taking a vacation day and skiing at Loveland Pass, in the Rocky Mountains not too far Denver. Finally, I have a chance to see if all my time spent on Mont Ripley has done me any good!

Fridays with Fuhrmann – ECE Undergraduate Programs

Published January 15, 2016

By Lisa Hitch

Winter break is over and the spring semester is underway at Michigan Tech – “spring” being a euphemism in Houghton for snow up to our eyeballs. I thought it might be a good time to write a few words about our undergraduate educational programs.

In the ECE Department we are all about teamwork and team projects. Our Senior Design program is a well-oiled machine with about 10 projects going each year, real industrial projects with real industrial financial support. Our Enterprise program, an alternative path to completion of the capstone design requirement, is unique to Michigan Tech; it gives students the opportunity to form their own virtual companies and work on projects that have longevity across semesters and across multiple personnel. Of course, we are not alone in this approach. All ECE Departments across the country recognize the importance the team-based design projects, as do the employers that hire new graduates every year. It is also a critical piece of everyone’s ABET accreditation.

What distinguishes Michigan Tech from many other institutions is our philosophy in the early part of the curriculum. We believe very strongly that the best path to becoming a valuable team member is to develop individual skills. I don’t think this is particularly controversial, and is unquestioned in other fields of human endeavor. Think of an orchestra, for example – every player has to know the technical aspects of playing his or her instrument, and enough music theory to understand what is going on. Or, think of a baseball team, where everyone has honed their skills in throwing, catching, and batting, and they know all the rules of the game. In both analogies, people bring their individual and diverse skills to the table, which makes the whole greater than the sum of the parts.

So it is in electrical and computer engineering. This is a wonderful and exciting field, with teams of people in major corporations and in small start-up companies changing the world every day through their ingenuity and innovation. The engineers who are going to make the biggest contributions are the ones who put in the effort early on to get really good at what they are doing. This needs to happen when students are young enough, and their brains are malleable enough, to learn new material with some degree of permanence – like playing the violin or learning to water ski. Author and social observer Malcolm Gladwell has pointed out that it takes about 10,000 hours to become an expert at something, and the 10,000 hours is about what you get by working 40 hours a week, 50 weeks a year, for 5 years – in other words, a college education. In the ECE Department we emphasize individual skills in both the mathematical and scientific fundamentals of electricity and electronics, and in the laboratory.

Our required sophomore electronics laboratory is a prime example. Each lab bench has exactly one chair in front of it. When I was interviewing for this position and getting a tour of the facilities, it was one of the first things I noticed, without anyone telling me. I was blown away by the elegance and simplicity of this approach to laboratory education. Each student is required to learn how to use the equipment and how to carry out the experiments, on their own, human against the machine. Not everyone is happy with this approach at first – not everyone is happy with two-a-day football drills either – but in the end I would be very surprised if any of our graduating seniors ever told me it was a bad idea.

We take a similar approach on the mathematical side of things. I teach a one-credit course to freshman called Essential Mathematics for Electrical Engineering. The scope is quite limited but I cover a few things that I think are critical in electrical engineering that don’t show up as much in other engineering disciplines – sinusoids, exponentials, complex numbers, complex exponentials, phasors, that sort of thing. Basically I want them to know Euler’s formula and what it means. (In fact, every semester I tell students that if they see me around town and can produce Euler’s formula from memory I will buy them whatever beverage they are old enough to drink. This has actually happened.) The course is pass-fail, and to complete the course the students have to pass an old-fashioned paper-and-pencil exam with no books, no notes, no nothing. The pass threshold is 70%, which is pretty draconian, but I give them up to three chances to pass it, kind of like a driver’s test. Again, this is consistent with our philosophy that there are few things that all EEs simply need to know cold, and there’s no getting around it.

Our goal is to set every student on a path where they can realize their greatest potential, whatever that looks like to them. We think that by instilling individual skills in younger students, and then putting students together as they mature so they can learn how contribute those skills in a team environment, is the best way to do that. So far it seems to be working.

From Tech Today by Systems Control

An Upper Peninsula company with ties to Michigan Tech has announced a major expansion. Systems Control has begun a 70,000 sqare foot addition that will bring the total footprint of the company’s headquarters and manufacturing facility in Iron Mt. to more than 315,000 square feet. This expansion comes on the heels of a 127,000 square foot expansion that was completed in 2012.

Systems Control is owned by Michigan Tech alumnus Dave Brule, Sr., ’72, who also served for several years as a member of the Michigan Tech Board of Trustees, culminating in a term as chairman in 2004.

In announcing his most recent investment in the Upper Peninsula economy, Brule stated, “Given our markets, we could have expanded our manufacturing capabilities anywhere in the country. I prefer to leverage the strong work ethic and technical expertise of residents in the Upper Peninsula. Quality and innovation are hallmarks of our success. Engineers and workers in the U.P. embody these traits.”

The additional space will be devoted primarily to the manufacture of equipment enclosures used in the electrical transmission, energy storage and oil and gas distribution industries.

Accompanying the investment in plant and equipment, Systems Control has embarked on a substantial program to develop and grow the human resource side of the business. In order to achieve its strategic goals, the company plans to add 70 to 150 people per year for the foreseeable future, possibly doubling its workforce by 2020. Immediate needs include electrical engineers, manufacturing engineers, project managers, CAD designers and many tradesmen.

In May, Systems Control established an engineering office in Houghton located in Michigan Tech’s Lakeshore Center, home of the MTEC SmartZone, on the Houghton waterfront. To learn more, visit the Systems Control website.
