Fridays with Fuhrmann: Thank you Mr. Dobelbower

Teacher with students in classroomThis is the first week of the Michigan Tech summer – a bit of a euphemism, since the leaves aren’t even out on the trees yet. I can remember a meeting of engineering chairs around this time a few years ago, after a particularly hard winter, when then-Provost Max Seel walked in and said “I have bad news for you. In six weeks the days start getting shorter.”

I am taking advantage of this somewhat quiet time in the calendar to visit family in my home town of Tulsa, Oklahoma. When I make trips like this, I like to carve out time to visit high schools and talk to math and physics classes about electrical and computer engineering and about Michigan Tech. Yesterday I visited Union and Memorial high schools and enjoyed my time with the students there. My cousin Donna Hardway is a math teacher at Union High School and made the arrangements for me (thank you Donna). Memorial High School has a highly successful FIRST Robotics team, and I was very impressed with the facility they have created for that activity.

I thought this would be a good time to pay tribute to all the high school teachers out there, especially the math teachers, that do so much to prepare the students that eventually come to places like Michigan Tech. We could not do our job without them. By and large they are overworked and underpaid, but are dedicated to their students. They work every day to prepare students to make the first transition from being children to being independent adults, and in a lot of cases preparing them for the next step which is college. One or two good teachers can make a huge difference in a kid’s life. Often this means guiding students to find out that they really are good at something, giving them the confidence to go on and follow their dreams, which might include, say, engineering. I just can’t say enough good things about them.

I graduated from Tulsa Edison High School in 1975. I took trigonometry and calculus in my junior and senior years, respectively, from a local teaching legend named Jack Dobelbower, who taught at Edison for 31 years. “Dobe”, as all the students called him, was an imposing figure of a man who had an uncompromising commitment to academic excellence. He assigned homework every night, and every class period began with 10-minute quiz on the previous day’s work. I don’t recall their being any other major exams, just those daily quizzes that forced us all to stay up-to-date. He made it clear that in his position between the students and the school administration, he was totally on the side of the students, even to the point of allowing students who were not feeling well to come to class, take the quiz, then declare themselves absent and go back home. He raised the bar for everyone, and did it with such passion and conviction that most students rose to the challenge. Because of that experience, I have always carried the thought that “a good high school calculus class will beat a college calculus class any day.” (That thought may be flawed – I know we have excellent calculus instructors at Michigan Tech too.) Dobe also had a mysterious personal life, and there were lot of wild rumors that he and his wife lived in a converted school bus in the country out west of town, and adopted lots of foster children. I can’t confirm or deny any of that, although these stories did lend a certain mystique that made him seem larger than life for us students. As I said above, one good teacher can make a huge difference, and that was absolutely the case for Jack Dobelbower and me. In my own teaching I try to live up to the example that he set, and if I can do that I will be happy and proud.

Many of the readers of this column who have gone on to a professional life in electrical and computer engineering will have similar stories. If any of this resonates with you, I encourage you to reach out and thank your high school teachers. Show your appreciation while you still have a chance.

I have to end this week’s column on a bit of a down note. I have learned over the past couple of years that there are a lot short-sighted politicians and demagogues who are slowly and systemically dismantling the whole public school education system in the state of Oklahoma. It hurts the economy, it makes the state look bad, and it’s just plain wrong. I stand firmly behind the teachers in this ongoing battle. I suppose that now that I live in Michigan I shouldn’t care so much, but these are my roots and I came out of an excellent public school that did a lot to shape me into the man I am today. I just hate to see that come undone. If you are reading this and feel that high-quality public education is important for our society, our culture, and our economy, please do what you can to support your local schools and the teachers that mean so much to all of us. Thank you.

Fridays with Fuhrmann: Congratulations graduates!

FWF_image_20160506Well, here we are at the end of yet another academic year at Michigan Tech. Last week saw a flurry of activity leading up to to commencement, so much so that I overlooked writing this very column! (I doubt if anyone missed it, but if you did you will make me feel good.)

A lot of parents and other family members came to town on Friday. I got to meet many of them at a reception for ECE students that we host here in the department, followed by another university-wide reception hosted by President Glenn Mroz and his wife Gail. Most of our students have good jobs lined up, as one might expect with the strong demand for electrical and computer engineers that I have written about before. I was struck this year by the handful of students who did not have definitive plans for the immediate future. I did not get a sense of concern about this at all, it was just that students were so busy doing other things that they had not yet mounted a serious job search. I am not at all worried about the availability of good jobs out there, only about the complacency (for a small minority) that comes with being in a seller’s market.

Saturday was the big day. For me it started at 7:30am with the commissioning of the ROTC candidates. This year Michigan Tech had 11 graduating students assume their first positions as 2nd lieutenants in either the Army or the Air Force. Two of those were ECE students, Carrie Shuler and Michael Bartkowiak. I congratulate them and thank them for their service. The main commencement in the Student Development Center was at 10:30am, and this year with 993 students graduating and walking across the stage it turned into a 3-hour and 10-minute affair. Our commencement speaker, Peace Corps Director Carrie Hessler-Radelet, reminded us to look for the good in all people and to consider the satisfaction of a life of service. Despite all the pomp and circumstance, and the long wait for the last student to get his diploma and get off the stage, it really is a great moment in the life of the university and one that always leaves me energized.

This year, including the Fall 2015 commencement, the ECE Department granted 72 BSEE degrees and 34 BSCpE degrees, for a total of 106 undergraduates degrees. That number is a little low for us, 26 fewer than last year. With 169 new undergraduates predicted to enter next year, we should see a big jump in the total undergraduate enrollment in the fall. On the graduate side, we produced 95 MS degrees and 3 PhD degrees, for a net increase in 4. Our MS numbers are up, but the PhD degrees are down, which is a concern considering our strategic plan to graduate 10 PhD students per year. However, I am told we have 12 PhD students ready to finish up this summer. The department is going to be hopping this summer if that comes to fruition!

As we wrap up the year I like to take a few moments and recognize a few people that do an outstanding job of teaching, research, and service in the ECE Department. I will repeat here some of the acknowledgements I made at the last faculty meeting of the year three days ago. On the teaching side, I like to recognize faculty members that handle very large classes and still get very good to excellent student teaching evaluations; these include Glen Archer, Duane Bucheger, Bruce Mork, Ashok Ambardar, and John Lukowski. I also want to congratulate faculty members with student course evaluations very close to 5 on a 0-5 scale in small and medium-sized classes: Tim Schulz, Ashok Ambardar, and Warren Perger in undergraduate courses and Joshua Pearce, Wayne Weaver, and Tim Havens in graduate courses. Thank you all for a job well done!

One of the key metrics that we use in evaluating the strength of our research programs is the number of PhD students supported by external grants and contracts. Our goal is to have 50% of the PhD students on external support, and while we are not there yet we get a little closer every year. This year we had 23 students supported by 13 different faculty members, both numbers larger than we have seen in quite a while. The faculty members are: Feng, Guney, Havens, Hu, Middlebrook, Mork, Nooshabadi, Roggemann, Semouchkina, Ten, Wang, Weaver, and Zekavat.  Special recognition goes to Prof. Christopher Middlebrook for having the largest research expenditures in the department this year. Nice going Chris!

A special acknowledgement goes to our relatively new Graduate Program Coordinator Joan Becker, for the extraordinary job she has done in meeting the needs of our graduate students. Our program has seen tremendous growth in recent years, and we do not have a faculty or staff position dedicated to academic advising for everyday things like making sure all the degree requirements are being met and the appropriate forms are turned in. This task has fallen to Joan, and she has really gone above and beyond taking care of the steady stream of students outside her door.

Another person I need to recognize is ECE faculty member Ashok Ambardar, one of our absolute top instructors. Prof. Ambardar is old school: he likes to lecture with chalk on a blackboard, assign regular weekly homeworks, and give regular paper-and-pencil exams, just like he has done his entire career. Students love him. Ashok had an amazing Fall 2015 semester, in terms of student enrollments and responses. He taught three courses – one sophomore, one junior, one senior – with enrollments of 76, 73, and 11, and bottom-line student course evaluations of 4.51, 4.37 and 4.82 out of 5. Prof. Ambardar goes about his work quietly and does not seek a lot of attention, but I hope he knows how much we all appreciate everything he does.

Finally, I want to recognize Senior Lecturer Kit Cischke, this year’s Eta Kappa Nu Professor of the Year. Kit is another amazing instructor, someone who shoulders a lot of the teaching responsibility in our computer engineering program. He teaches courses in microcontrollers, hardware/software integration, and computer networks, and is the faculty advisor for the Wireless Communications Enterprise. His many students realize what an impact he has on their lives and here in the ECE Department. Congratulations Kit on being recognized by our students and thank you for everything you do!

I think that’s about it for this year – students have cleared out, and spring has returned to the Keweenaw.  Have a great summer everyone!

Fridays with Fuhrmann: ECE careers for the good of the Earth

FWF_image_20160422Today, April 22, is Earth Day, so it seems appropriate to say a few things about the environmental impact of the work of electrical engineers.

Actually, there is a whole lot to say, much of it surrounding the topic of generation, transmission, and distribution of electrical power. This is not my own area of technical expertise – I am more of a communications and signal processing engineer – so I have to exercise caution in pontificating too much on the topic. I will hasten to point out this is an area of strength for the ECE Department at Michigan Tech, as it has been ever since the department was founded in 1928. We have a lot of good people contributing to the next generation of power and energy technology, and to the education of the next generation of power and energy engineers who are going to make that technology work.

It is safe to say that the development of electrical power has had a huge impact on human civilization over the last 100 years. As a species, we learned how to burn fossil fuel in enormous rotating machines, and through the magic of electromagnetic induction we convert that mechanical energy to electrical energy which can be transmitted over long distances and distributed to homes and businesses everywhere. The development of “universal electrification,” as this is called, was named the #1 technical achievement of the 20th century by the U.S. National Academy of Engineering. It has had an immeasurable positive effect on the standard of living and quality of life for us all. Think about that the next time you turn on a light switch in the middle of the night.

We now understand that this technological advancement comes with a certain environmental cost. One cannot burn fossil fuel without putting some residue back into the atmosphere, and the consensus of the vast majority of professionals who know what they’re talking about is that this is having a detrimental effect on our world (I don’t claim to be one of those people.) As electrical engineers we have to take some responsibility for that problem. Fortunately, if we are part of the problem, we are also part of the solution. A great many smart, dedicated electrical engineers are looking at alternative means for generating and distributing electrical power that do not have the same environmental cost, or so we hope. I can’t begin to go into all the technology and the tradeoffs in alternative and renewable energy generation, and the smart distribution systems that go with them – we have entire courses on that topic – but I encourage all young engineers with a passion for making a big contribution to the planet to consider this as a career possibility.

From my own casual observations, I see a lot of potential in solar power. Everything that we are and everything we consume ultimately comes from the sun anyway. I am particularly fascinated by passive solar technology, whereby arrangements of mirrors are used to concentrate solar energy, creating localized areas of intense heat for turning steam turbines or melting salt. I can’t help but think that there is a lot of real estate in the desert Southwest of the United States where such technology could easily be deployed. [I’ll probably catch a lot of flak from some people for that position – the desert is much more than a lot of sun-baked nothingness, and I get it – but it’s easy to see how one might get that impression when you fly from here to California.] The dropping costs and widespread adoption of solar photovoltaics is a positive sign too – although from an environmental perspective one needs to factor in the cost of acquiring natural resources and manufacturing the panels.

I’m not a big fan of wind power (no pun intended), mostly because I think that the big wind farms popping up all over American farmland are kind of ugly. Other people find them stately and beautiful, so I am willing to be wrong about that. As an alternative means of providing much-needed power that we are most certainly not going to give up, I can see the value. I did read a fascinating article recently in IEEE Spectrum about how wind power is a testament to our dependence on fossil fuel, when one considers everything that goes into the manufacturing, transportation, and deployment of wind turbines: see

Steering away from power and energy for a bit, let me add that there are other ways that electrical engineers can practice their trade and have a positive impact on the environment. Watch out for water as a big growth area in the coming decades. Water is something we all take for granted, until something goes horribly wrong as it did with the recent slow-motion trainwreck in Flint. People are now talking about the “water-energy nexus” in which our dependence on water and energy makes one big interconnected system: we need water to produce electrical energy, and we need electrical energy to produce clean water. I foresee a lot of important work to be done, and also a lot of career opportunities.

I’ll use that last assertion to put in a plug for our new Concentration in Environmental Applications, offered as part of our undergraduate degree in electrical engineering at Michigan Tech. We created this concentration to give students with an interest in air quality, water quality, and/or remote sensing an opportunity to pursue those interests and at the same time apply their engineering talents. There are going to be a lot electrical engineers needed for the electrical machinery, automation, industrial control, communication, and signal processing that go into the systems that monitor and improve our air and water quality. Please take a look if that sounds interesting – the ECE Department will be happy to provide all the information you need.

Happy Earth Day!

(Also – happy last day of classes to all our graduating seniors! Take it easy on Senior Walk, OK?)

Happy Tax Day everyone! Actually the real Tax Day this year isn’t until Monday, and that’s a good thing considering how busy things have been in the ECE Department this week. Here’s a little factoid I just learned this week: April 15 is the birthday of Swiss mathematician, physicist, and astronomer Leonhard Euler (1707). Everyone knows Euler’s Formula, right?

This is the time when all our seniors are wrapping up their Senior Design and Enterprise projects, and we have a lot of visitors in town to see what we are doing and to help us out with the evaluation of the projects.

The ECE External Advisory Committee, or EAC, is here for the Spring 2016 meeting. This is a group of about a dozen industry representatives, most of them Tech alumni, who visit us twice a year to help us in our quest for continuous improvement. A lot of their time in the spring meeting is devoted to judging Senior Design and Enterprise projects, which happened yesterday (Thursday April 14). We had a total of 24 projects this year, and each project team is required to present their results and field questions in a 45-minute session. All of the ECE faculty and the graduate student TAs also participated in the judging. This is a great day in the life of the ECE Department, when we get to see all the hard work of the students over four years brought to fruition. My thanks to everyone, especially the EAC, that helped make the day a success.

We concluded the day with the Senior Awards Banquet at the Memorial Union Ballroom. Here we recognize both individuals and teams for their outstanding contributions to the ECE Department.

The individual student award winners are:

ECE Woman of Promise / Martha Sloan Scholarship: Alexis Dani (pictured above)
ECE Departmental Scholar: Derek Gheller
Carl S. Schjonberg Outstanding Senior: Ian Cummings

Earlier in the week we had a visit from another “unofficial” advisory group – a group of 5 industry leaders and entrepreneurs from Silicon Valley, led by Brocade CEO Dave House. Dave has been a very good friend of the ECE Department for many years, and in fact you may recognize his name from the professorship that I hold. Dave and company were here to advise and encourage the entire university, not just the ECE Department, on matters of innovation, entrepreneurship, and where technology is headed from their point of view. Dave has been very influential on my thinking about the importance of building closer ties among the ECE Department, the Department of Computer Science, and the School of Technology. On Tuesday I was very pleased to be able to report to the group that the performance results in the new Institute of Computing and Cybersystems, measured in new research awards, research expenditures, publications, and student support, was much higher than expected. The ICC is the most significant effort arising from the joint activity of the three units mentioned above, and so it is gratifying to see things coming together as they are.

On top of all that, we had some fantastic news from the ECE faculty this week. Assistant Professors Durdu Guney, Timothy Havens, and Chee-Wooi Ten have all been recommended by the Provost for promotion to the rank of Associate Professor, with tenure. The final vote will be taken at a meeting of the Board of Trustees in two weeks’ time. My congratulations to Durdu, Tim, and Chee-Wooi on reaching this major milestone – we expect many great things from them in the years to come.

All for now. Get those taxes in!

Fridays with Fuhrmann: The image of ECE

FWF_image2_20160408A couple of weeks ago I attended the annual meeting of the Electrical and Computer Engineering Department Heads Association, or ECEDHA, in San Diego. I enjoyed seeing old friends, making new ones, and having good discussions about a number of issues that we have in common and may not realize.

One of those issues is that of the ECE “image”, that is, how the general public, and specifically prospective students and their parents, views the field of electrical and computer engineering. There is a lot of angst and hand-wringing over the fact that we as a profession are not widely known or appreciated for what we have accomplished, and that in fact we are “losing ground” to other disciplines who are moving in on our turf.

This brings up a couple of thoughts for me. The first is, should we be worried about this at all? I think I will put that one off, and today I will offer a couple of observations on how I think we got to this point.

First of course is the “nerd” stereotype associated with electrical engineers, and engineers in general. This is promulgated in popular culture – think e.g. of the comic strip Dilbert, or Wollowitz in “The Big Bang Theory”, or many of the characters in “Revenge of the Nerds.” We all cringe at these stereotypes, although most of us in our heart of hearts will admit there is a kernel of truth in them; some even embrace them fully. Still, it is a constant battle to convince young people that one can be an engineer and still live a happy, healthy, productive, and well-adjusted life. I do what I can when given the opportunity.

A second issue is the “invisibility” part, that is, no one knows who we are and what we do. In this regard I think that as electrical engineers we have become a victim of our own success. We happen to work on systems that depend wholly or in part on the manipulation of electricity – voltage, current, electric fields, and the like – and it just turns out that of all the forces of nature in the universe, electricity is probably the most malleable. We can do things at unbelievable scales of both space and time. We can make electrical devices change their state a billion times a second, and can put a billion different such devices on a chip no bigger than a square centimeter. As a consequence, we can build systems that do unbelievable things, like a smart phone that connects to the Internet and downloads and displays videos from half a world away. The problem is, this technology is so successful that it is adopted quickly and commoditized. It is so useful and popular that people will just assume that it exists (or even claim that they have right to it) and they are unaware where it came from and the effort that it took to bring it to market. One can say this about electrical power to the home, telephone service, radio, TV, audio systems, medical instrumentation, computers – the list goes on and on. All this stuff just showed up in our lives in the space of two to three generations. But if you ask kids who invented the iPhone, guess what they will tell you, almost certainly: scientists.

It may be that part of the reason we as a profession are invisible is that the stuff we work with – electricity – is also invisible. The work of a mechanical engineer is obvious in the motion of an automobile, and the work of a civil engineer is obvious in the structure of a bridge. It’s there for all the world to see. However, people just have to take our word for it when we say we are pushing electrons around for the benefit of humanity. You can see the results of our work – that video downloaded to your phone, say – but everything that made that happen remains a mystery to most.

What to do about this situation? I suppose we have to address the first question I asked, namely, should we worry about it at all? Stay tuned; I’ll pick that up another day.
