Fridays with Fuhrmann: Thank You Dave!

FWF-image-20170310Greetings to all from the road. I have been out of town for a little over a week, on a trip that combined a little bit of work and a little bit of vacation. Actually a lot of vacation. Last weekend and in the early part of this week I was in Steamboat Springs, Colorado, seeing if my skills in downhill skiing, developed over many evenings and weekends at Mont Ripley, would carry over to a larger – much larger – resort in the Rockies. I am happy to say that they did; I had a wonderful time! From what I can tell the average skill level at Mont Ripley is higher than what it was at Steamboat. That’s because a lot of the people who go to a faraway mountain resort are duffers like me who go there for vacation, and are not regular expert skiers. I felt right at home. I can also report that, after nine years in the U.P., my tolerance for cold seems to be higher than that of the average flatlander who goes to Colorado. That’s a good thing, because from what I understand I’ll be coming home to some of the coldest weather of the winter.

The work-related part of my trip took me out to the San Francisco Bay Area, which I often visit during spring break. It was there that I had the chance to visit Dave House, the namesake of the professorship I now hold and my mentor for the time I have been at Michigan Tech. I had both a private meeting with Dave, and I attended a Michigan Tech alumni event that Dave hosted at the tasting room for the small winery that is part of his beautiful home and property in Saratoga. The setting for the latter event has a stunning view of all of Silicon Valley, and was a perfect setting for the gathering of about 50-60 people. Dave and his wife Devyani were gracious hosts, keeping the conversations lively and providing some of the best food and wine in California. Everyone had a lovely evening.

Reflecting on this short trip this morning, I thought it would be a good time to acknowledge Dave for everything he has meant to Michigan Tech and to me personally. Dave is a 1965 graduate of the Michigan Tech EE Department. He began his career working on radar systems for Raytheon in the Boston area, where he completed an MS degree at Northeastern University. He later switched over to computer engineering, and moved to California to begin a long career at Intel where he moved up the ranks from hardware engineer, to engineering manager, and eventually to Vice-President reporting to the late Andy Grove. He was responsible for the “Intel Inside” campaign which made a household name of the otherwise invisible processing hardware that drives untold numbers of personal computers and laptops. After a couple of other high-visibility positions in Silicon Valley, Dave is now the Chairman of the Board of Directors at Brocade, a market leader in optical networking equipment.

What sets Dave apart from so many other successful innovators in Silicon Valley is his unwavering commitment to giving back to the institutions where he got his start, both Michigan Tech and Northeastern. He has been extraordinarily generous in terms of both his financial gifts, and more valuable still his gift of time and effort to move the institution forward. The professorship that I hold is one of four that he has endowed at Michigan Tech. Two of the others are held by the Dean of the College of Engineering and the Chair of the Department of Computer Science, respectively, and the fourth is split between Associate
Professors Wayne Weaver and Bo Chen. The professorships come with more than money; they come with regular advice and mentoring in management, leadership, and innovation for which Dave is an acknowledged master. When I first arrived at Michigan Tech, Dave and I spent the better part of a day together, going through what we jokingly refer to as “House
Training.” His efforts on behalf of Michigan Tech are not just for my benefit; he has worked hard with many other leaders at the university at all levels. His financial gifts go well beyond the professorships mentioned above; he is responsible for the founding of the Michigan Tech Research Institute in Ann Arbor, and he is providing support for visiting faculty in the newly formed Institute of Computing and Cybersystems. He was the Chairman of the Michigan Tech’s Generations of Discovery capital campaign that ran from 2006 to 2013 and raised over $215M for the university.

One of Dave’s goals over the past years has been to bring the spirit of innovation and entrepreneurship one finds in Silicon Valley back to Houghton. These efforts including bringing teams of other executives and entrepreneurs from California to campus for meetings, panel discussions, and other events meant to raise awareness of where we need to be going, and to get feedback on who we are doing. Dave has been instrumental in instilling in many of us the importance of setting goals that are both meaningful and measurable. Many of his visits include “progress reports” where we get very specific about how we are doing relative to the metrics we are using to define success. The idea of such a goal-oriented approach to academics was new to me when I first arrived at this position, but now I find it perfectly natural and I can’t imagine doing business any other way.

Dave and I don’t always agree on everything, and sometimes he gives me a hard time when he thinks our progress is not what it ought to be, by our own standards. That’s the way it should be. There is always a good give and take, and he always lets you know where he stands.

Dave and I share a common vision: the best Michigan Tech that all of us working together can possibly create. I know I speak for many of us at Michigan Tech when I say: thank you Dave for everything you do!

p.s. while I am in the mood for thank-yous, let me add three others: 1) Tim Schulz, former ECE Department Chair and former Dean of the College of Engineering, who is responsible in large part for re-engaging Dave with Michigan Tech many years ago; 2) Gwen Caldwell, Dave’s very capable personal assistant whom I met for the first time last night and who has never been anything but perfectly friendly and professional, and finally 3) Adam Johnson, our unflappable and ultra-hip Michigan Tech “tour wrangler” for all the House-related activities on campus and in California.


Fridays with Fuhrmann: Spring Break

FWF-image-20170303-pic2Today is the Friday of Week 8 in the spring academic calendar, and last regular class day before spring break at Michigan Tech. Things are pretty quiet around campus, as many students and faculty members head out for a variety of activities elsewhere. At least, I assume that is the case: I am not on campus to observe, as I am on the road myself for a trip that is a little bit work and mostly vacation.

This day is a special one for me. It was on the Friday before spring break in 2008, nine years ago, that I first set foot on the Michigan Tech campus. Then-dean Tim Schulz picked me up at the airport late Thursday night, after his weekly hockey game, and dropped me off at the hotel; on Friday I spent the day on campus learning all about the ECE Department, and gave a technical seminar on my work on adaptive sensing. It didn’t take long for me to realize that this was where I wanted to be. Tim figured out how to push all my buttons. In addition to everything we did on campus, he arranged social events with people who would eventually become good friends, showing what a strong sense of community we have in our little town. He took me cross-country skiing on the Tech Trails, and we even went out to McLain State Park and walked around on Lake Superior ice! It must have been a colder winter than what we are having this year. Tim was a master recruiter and I have tried my best to follow his example in our faculty searches over the past nine years.

The halfway point in the semester (which was actually last week, not this one) means the conclusion of the course I teach, EE 1110 Essential Mathematics for Electrical Engineering. I sometimes struggle with balancing the competing responsibilities of teaching, research, and department administration, but on the teaching side I have found a good compromise by teaching this 1-credit course in a half-semester format. I stay in town in January and February, which is perfectly fine with me, and the second half of the semester is available for travel and other larger administrative tasks. This semester we had 144 students enrolled in EE1110, which makes it the largest course I have ever taught. With such a large class, I don’t get much of a chance to get to know many of the students personally, but I do enjoy taking a group of students with a diverse set of talents and abilities and doing what I can to get them ready for our regular EE curriculum. You’ll have to ask them if I was successful or not.

I am a big believer in the notion that, as a public institution, Michigan Tech has a responsibility to provide something of value to all our students, who come from all walks of life and all different levels of preparation and training. We don’t have the luxury of being ultra-selective, but I couldn’t be prouder of the job we are doing to prepare students for careers in engineering, whether they are class valedictorian or come from the middle of the pack in their high schools. I have designed EE1110 with this in mind. Students have three chances at the final exam. Some breeze through it on the first try, others study a bit more and are successful the second time. Some students need all three chances, and I don’t have a problem with that – I’m in favor of whatever they need to do to demonstrate mastery of the material before moving on.

With EE1110 behind me for this semester, I plan on spending time in March and April crafting our strategic goals and our strategic plan for achieving those goals. We do this on a three-year cycle, and this time I would like to have our plan in place before the start of the next academic year. The entire faculty will need to agree on the plan, so there will be a fair amount of discussion and wordsmithing before the final document is approved. I am optimistic this can be accomplished before the faculty go in all different directions in May. The biggest challenge will be doing this at the same time we are preparing for our ABET visit, which is coming up next fall. Never a dull moment!

The little bit of work alluded to in the first paragraph happens toward the end of next week, when I will be in California. The vacation part starts today. Happy spring break everyone!

McGrath Receives Project GO Scholarship

McGrath-NatalieNatalie McGrath will be spending her summer in Narva, Estonia this year to further her studies in Russian language and culture.

Natalie was recently awarded a Project Global Officer (Project GO) scholarship through the University of Pittsburgh’s Center for Russian and East European Studies. Project GO is a collaborative initiative with the Department of Defense aimed at improving the language skills, regional expertise, and intercultural communication skills of future military officers within all of the U.S. Armed Forces.

In just eight weeks, students cover the equivalent of one academic year of training in a designated critical language, as well as weekend excursions and cultural activities. Scholarship awardees receive full tuition for the 8-credit University of Pittsburgh language course, coverage of travel, lodging, and textbook costs, and a living stipend for meals.

Natalie is a second year computer engineering major in the Department of Electrical and Computer Engineering and a member of the Army Reserve Officer Training Corps (ROTC) at Michigan Technological University. She received a domestic Project GO scholarship in the summer of 2015 and studied first-year Russian at Indiana University in Bloomington.


Fridays with Fuhrmann: Engineers, Go Fourth

FWF-image-20170224This week is Engineers Week, a national celebration of all things engineering, and as you might imagine there are a number of activities going on around campus that raise awareness of the field (like we need that here) and generally give us the opportunity to feel good about who we are and what we do. Although the ECE Department does not take a lead role in organizing the week’s activities, various corners of the department such as the Blue Marble Security Enterprise are participating. This past Wednesday was also the date of the spring Career Fair, when companies and organizations come to campus to recruit our students for co-ops, internships, and full-time jobs. The spring fair is always smaller than the one in the fall, but with 219 recruiting organizations on campus it is still respectable by anyone’s standards. As usual, a lot of companies are looking to hire electrical engineers and computer engineers, a theme I have touched on many times before. This weekend the fun will continue with a student-organized and student-led hackathon called Winter Wonderhack. We expect a fair number of Michigan Tech students, some students for other universities in the region, and maybe a few high school students too, on campus showing off their chops in creativity and invention.

This seems like a good week to talk about where technology is going, and the role that an organization like the ECE Department can play. I recently read the book “The Fourth Industrial Revolution” by Klaus Schwab, and thought I would offer a few thoughts about it.

Schwab is the founder and executive chairman of the World Economic Forum, the annual meeting of world leaders in government and industry held in Davos, Switzerland. This meeting draws a lot of heavy hitters – including, sometimes, the President of the United States – and as a result it gets a fair amount of press. The theme of the 2016 WEF meeting was “Mastering the Fourth Industrial Revolution” and Schwab’s new book provides a succinct companion volume to that meeting. The concept of the Fourth Industrial Revolution has been around for a while, and I have even used it for several years in some of my own presentations to prospective high school students and first-year students at Tech. The promotion of the idea through the WEF brings it to a higher level of visibility in industry, government, and in the public imagination.

The basic idea is that human society has been through a series of transformative periods in our history, brought about by technological innovations, that each time have fundamentally altered the way we live and work. The First Industrial Revolution (the one often taught in high school as THE Industrial Revolution) occurred in the period from 1760 to 1840, and is characterized as the change from human and animal labor to mechanized work, exemplified by the steam engine. The Second Industrial Revolution occurred around the turn of the 20th century, with the rise of mass production and assembly lines, made possible by the widespread use of electrical power. It was during this time that “action at a distance” became commonplace – one could burn a lump of coal at one place and turn on a light somewhere else. Or, one could tap a key in a telegraph office and information would instantaneously appear 50 miles away. Or, with the aid of refrigeration, food could be grown on a farm and days or weeks later consumed in the city. The Third Industrial Revolution, in the 1960s and 1970s is associated with the rise of computers, and the use of computers to automate many manufacturing and information processing tasks.

The Fourth Industrial Revolution is, at its core, all about connectivity. While computer technology developed rapidly in the latter part of the 20th century, the tasks being performed were tasks that we were already doing. In contrast, the connected nature of all the computers and sensors in the 21st century is fundamentally altering our daily lives – not only how we do things, but what we want to do in the first place. The Internet is largest and most visible of this movement, but in truth the Internet is only just the beginning of this revolution. Now we are moving into the era of the “Internet of Things” (IoT) or the “Internet of Everything” where all the objects and devices in our lives, whether for personal use or for business, manufacturing, or process control, will be connected through one vast network of sensing, communication, and control. “Cyber-physical systems” is a term used to describe the convergence of digital and physical technology that is happening alongside the IoT.

One of the aspects of the current industrial revolution, which sets it apart from the previous three, is the speed at which technology is developed and subsequently adopted. The Internet has gone from an academic curiosity to the primary engine of communication and commerce in the space of 20 years. Amazon was founded in 1994, Google in 1998. The first iPhone was introduced in 2007, and now there are an estimated 2 billion smartphones worldwide. AirBnB and Uber were unknown 5 years ago, and are now household names. Right now autonomous vehicles are the subject of vigorous research and development, but according to many enthusiastic (and optimistic) advocates they could be on the roads by 2021. Imagine the day when autonomous vehicles are as common, and as accepted as normal, as the smartphone is today!

Klaus devotes much of the book to the impact of the Fourth Industrial Revolution, as well he should. I imagine this is in keeping with the many discussions taking place at the World Economic Forum, as leaders grapple with all the implications of this revolution in their respective constituencies. I don’t have the space here to discuss all those implications at length, but I can say a few things about the impact on my own constituency: electrical and computer engineers at Michigan Tech. A good place to start is with the list of 23 “shifts”, as Klaus calls them in the appendix of the book, itself an outgrowth of a 2015 WEF survey report. These are the major technology trends associated with the Fourth Industrial Revolution, and each associated with a “tipping point”, the point at which a technology moves from being a novelty to a necessity. They are:

1. Implantable Technologies
2. Our Digital Presence
3. Vision as the New Interface
4. Wearable Internet
5. Ubiquitous Computing
6. A Supercomputer in Your Pocket
7. Storage for All
8. The Internet of and for Things
9. The Connected Home
10. Smart Cities
11. Big Data for Decisions
12. Driverless Cars
13. Artificial Intelligence and Decision Making
14. AI and White-Collar Jobs
15. Robotics and Services
16. Bitcoin and the Blockchain
17. The Sharing Economy
18. Governments and the Blockchain
19. 3D Printing and Manufacturing
20. 3D Printing and Human Health
21. 3D Printing and Consumer Products
22. Designer Beings
23. Neurotechnologies

When I look at that list, and I cannot help but think – wow, there is a lot of work here for electrical and computer engineers. It is not exclusively ECE related technology, of course, but we will have our fingerprints all over it, probably more than any other discipline with the possible exception of computer science. This is precisely why I bring up the Fourth Industrial Revolution when speaking to young students with interests in STEM: this is what is coming, and the world needs you to make it happen.

I also notice in this list that, while on the surface it looks cheerful and optimistic, there are also a lot of technologies that could be subverted by those who seek to do harm to others. For this reason, cybersecurity will be a hugely important component of the Fourth Industrial Revolution. While he does not discuss security in the appendix, Schwab does cover it elsewhere, touching on the changing nature of conflict, cyber warfare, autonomous warfare, the militarization of space, and related topics.

The challenge for us in engineering education is to make sure that we are preparing students to enter this world. I see two complementary aspects to this. First, we must be certain that we continue to stress the fundamentals – after all, the laws of physics do not change (as I saw in an electronic product slogan tagline once, they are just more rigorously enforced.) Time spent learning the timeless truths of mathematics is never wasted. At the same time, we must be aware of these disruptive technologies and be certain that our students’ mastery of fundamentals is not diverted to the mastery of obsolete technology. We must also be certain that students have the skills, in the right proportion of depth and breadth, to be valuable not only for their expertise in a very narrow slice of technology but also for their broader understanding of the context for their expertise. For this reason, I am a believer in the “T-shaped” knowledge base that Robert Lucky alludes to in his column in the January 2017 issue of IEEE Spectrum – a deep specialty combined with broad understanding. Looking over Klaus’ list of 23, I would argue that, for our students, the horizontal arm of the T would encompass at least three major disciplines: electrical engineering, mechanical engineering, and computer science. The vertical arm would be the particular specialty, which could dive deep into some sub-specialty within one of those three disciplines. I am convinced that someone with that combination would find a world of opportunity laid at their feet.

Klaus’ book is relatively short but it raises a lot of important points that can serve as the basis for many fruitful discussions. These are exactly the kinds of discussions that I hope that we will have here at Michigan Tech as we imagine our own future. After all, our informal slogan is “Create the Future” and that applies to the institution just as much as it does to our students. Institutions such as ours are the engine behind the Fourth Industrial Revolution and where it is headed is largely up to us. Will we be in the driver’s seat?

ECE’s Microfabrication Facility launches new website

MFF_homepage Michigan Tech’s Microfabrication Facility, housed under the Department of Electrical and Computer, has launched its new website mtu.edu/microfabrication.

The Microfabrication Facility (MFF) consists of thin film, plasma etching, photolithography, and temperature processing equipment. MFF capabilities are broad and applicable to areas of biomedical engineering, chemistry, chemical engineering, electrical engineering, physics, materials science, and mechanical engineering. Deposition, sputtering, etching, and photolithography capabilities together with microcharacterization measurement systems enable precision device engineering.

The new site enables users to schedule reservations and check the live status of the MFF equipment, along with other user friendly features. MFFmenu

The MFF was also recently selected as a member of the Northern Nano Lab Alliance (NNLA), a regional network of university fabrication facilities. The mission of the NNLA is to help each member improve their support of academic research in applied nanotechnology.

MFF managing director Chito Kendrick, PhD, says “Being a member of the NNLA allows for a partnership with some of the local regional universities that have similar nano/micro fabrication facilities, and will indirectly expose Michigan Tech to the National Nanotechnology Coordinated Infrastructure (NNCI), which has replaced the National Nanotechnology Infrastructure Network (NNIN). This opens up availability to systems that are currently not provided by the MFF. The partnership will also benefit the MFF staff with access to technical support and loaning equipment from the other groups; also we are exploring ways to reduce the operational costs of these facilities.”


Fridays with Fuhrmann: Our Extraordinary Assistant Professors

FWF-image-3-20170217The life blood of any academic department is the faculty, and one of the keys to maintaining an intellectually healthy and vigorous faculty is the regular infusion of new talent and all the fresh ideas that come with it. I am happy to say that over the time that I have been here, the ECE Department has been fortunate to be able to bring in a number of new young faculty members, and doubly fortunate that they have been successful in so many different ways. Today I want to give a special shout-out to that side of our department.

By way of background, for those not completely familiar with the U.S. system, at most universities there are three ranks of tenured and tenure-track faculty: Assistant Professor, Associate Professor, and Professor. Anyone with the word “Professor” in their title is expected to be recognized as a scholar in his or her respective field, and to be able to translate that scholarship into effective classroom teaching. The usual duties of someone in these ranks is said to include teaching, research, and service, and the allocation of time and efforts among these three legs of the academic stool can vary quite a bit. Assistant Professors are near the beginning of their academic careers; they usually hold the PhD degree and may have some prior experience such as a post-doctoral fellowship. They are said to be “tenure-track” meaning that they will be seeking tenure after some period of time, typically six years. Associate Professors are more mid-career, continuing on the successful path that was begun earlier, and perhaps exploring new ideas, research areas, and collaborations. Tenure, the guarantee of lifetime employment to successful faculty members, is usually granted at the time of promotion from Assistant Professor to Associate Professor. Professors are the well-established faculty members who have built a strong track record in research and teaching, and are recognized nationally and internationally for their scholarly contributions. Professors often take on leadership positions within in the department or the university as well.

In the ECE Department right now we have four faculty members at the rank of Assistant Professor. At this time last year we actually had seven, but three of those – Durdu Guney, Tim Havens, and Chee-Wooi Ten – we promoted from Assistant Professor to Associate Professor last spring. I was delighted that all three were able to run the tenure and promotion gauntlet and emerge successfully at the other end. I had thought that three in one year must be a record, until Martha Sloan informed me that she was in a group of six such faculty members many years ago! We are happy for this group, and they are continuing to make us proud just as I knew they would.

Our four current Assistant Professors, in no particular order, are Jeremy Bos, Lucia Gauchia, Zhaohui Wang, and Sumit Paudyal. It has been a great year for this group, and over the past month or so we have gotten some wonderful news which has prompted this week’s column. Collectively they have been awarded three early-career awards: two National Science Foundation (NSF) CAREER awards, and one U.S. Air Force Young Investigator Program (YIP) award. These awards give young faculty members the time and resources to build a strong foundation in research. Their success reflects a lot of hard work, definitely a lot of perseverance, and a little bit of good luck too. Fortune favors the prepared mind.

Dr. Jeremy Bos is a 2013 PhD graduate of our own program, working (then) under the supervision of Dr. Michael Roggemann in atmospheric and statistical optics. He continued in this line of research for two years under an Air Force post-doctoral fellowship on the island of Maui, before returning to Michigan Tech in 2015 to take up his current position. He is the recipient of a three-year Air Force YIP award, titled “Imaging Theory and Mitigation in Extreme Turbulence-Induced Anisoplanatism.” His research will help the Air Force to see objects over long distances through turbulent media, such as the atmosphere, which causes light paths to bend in unpredictable ways and wreaks havoc with conventional optics and image reconstruction. Jeremy also has a separate and practically unrelated technical interest area, namely robotics, control, and automation, which stems for his time as a engineer at GM prior to coming to graduate school. He is playing a critical role in helping the ECE Department develop a strategy for expanding our robotics programs, all the way from graduate research, to undergraduate teaching, to pre-college outreach. It’s like having two faculty members in one!

Dr. Lucia Gauchia came to Michigan Tech in 2013, originally from Spain and most recently (at the time) a visiting position at McMaster University, in Hamilton, Ontario. Her area of interest is in energy storage systems, which covers the different ways that we can store energy that has been generated electrically so that it can be used at a later time. Utilities and consumers need energy storage to balance the generation of electrical power with the demands of electrical loads – often the two are out of sync. Because energy conversion is of interest to both electrical engineers and mechanical engineers, Lucia holds a joint appointment in the ECE Department and the Department of Mechanical Engineering-Engineering Mechanics at Michigan Tech. She holds an endowed position, the Richard and Elizabeth Henes Assistant Professor of Energy Storage Systems. Her cross-listed graduate course in energy storage systems is increasingly popular each year, and she gets very high student course evaluations for it. Lucia is the recipient of an NSF CAREER award, titled “An Ecologically Inspired Approach to Battery Lifetime Analysis and Testing.” She plans to borrow ideas from lifecycle analysis and population dynamics to understand better the performance and potential failure modes of batteries and battery packs, an increasingly important component of utility power systems, automobiles, and a myriad of other applications of electrical power.

Dr. Zhaohui Wang also came to Michigan Tech in 2013, having just completed her PhD with a very successful group at the University of Connecticut. Her work is in underwater acoustic communication networks. She had originally came in on a “computer engineering” search, but she has proven herself to be an able contributor in signals and systems as well. She teaches courses in wireless sensor networks, detection and estimation theory, and for the first time this semester our required undergraduate course in communication theory. Because of her interest in underwater acoustics, she is a member of the Great Lakes Research Center (GLRC) and has a large and expanding laboratory there. Zhaohui is the recipient of an NSF CAREER award, titled “Online Learning-Based Underwater Acoustic Communication and Networking” which will support much of her research for the next five years. She plans to develop methods for communication among multiple underwater surveillance platforms that take advantage of real-time modeling of underwater acoustic communication channels, which are dynamic and can be very complicated. This is an ambitious project combining elements of communication theory, signal processing, and physics. I can’t resist mentioning that Zhaohui was featured on the cover of our 2015 annual report (my favorite cover ever) walking across the ice on Keweenaw Bay in the dead of winter, where she and her graduate students were drilling holes in the ice and carrying out under-ice acoustic communication experiments.

Dr. Sumit Paudyal is the senior member of this group of young faculty. He came to us in 2012 with a PhD from the University of Waterloo, in Ontario. His work is on the electrical power side of the ECE Department, by far the most popular area among our current MS students. His research and teaching area is in optimization and control of power systems. He is the lead Michigan Tech investigator on a project sponsored by ARPA-E (Advanced Research Projects Agency – Energy) in collaboration with the University of Vermont, titled “Packetized Energy Management: Coordinating Transmission and Distribution.” The aim is to improve the ways that power grids take advantage of multiple intermittent energy sources, such as solar panels and wind turbines, borrowing some ideas from packet-switched communication (the essential idea behind the Internet.) Sumit is an outstanding teacher, with large graduate classes and very high student course evaluations; in fact, he has been recognized by the university through induction into the Michigan Tech Academy of Teaching Excellence. I recently did a little back-of the-envelope calculation, and discovered to my delight that, considering tuition revenue, course evaluations, and research expenditures, Sumit has made himself the third most valuable member of the ECE Department!

I get to work with a lot of wonderful people every day – our faculty, our staff, and our students. These four are among the best. We are proud to call them our own here in the ECE Department, and I look forward to many years of a mutual rewarding relationship.

Glen Archer Selected For Dean’s Teaching Showcase

archerThis week the Deans’ Teaching Showcase returns to the College of Engineering. Dean Wayne Pennington has chosen Glen Archer, principal lecturer and associate chair in the Department of Electrical and Computer Engineering.

Dan Fuhrmann (ECE chair), recommended Archer because of his long history of teaching EE3010, a service course primarily populated by other engineering majors.

Besides being very large (enrollment was 193 last fall), students tend to find the material difficult and perceive it as not directly related to their major. Despite these challenges, Archer earned an “Excellent Teacher” rating of 4.36 on a 5 point scale.

Fuhrmann wrote, “In addition to this traditional teaching assignment, Glen also teaches students in a wide variety of less formal venues. Glen serves as a mentor to two Enterprise groups. He has been a long-time advisor of Blue Marble Security. Recently, as an overload, he enthusiastically embraced adding the Robotics Systems Enterprise and has already grown membership in that enterprise from five to 30 students.

“Glen also leads departmental efforts to assemble course offerings and the binder process for the department. He also assigns and mentors the graduate teaching assistants in ECE, and has been known to have them to Thanksgiving dinner at his home in some years.

“But when asked about his favorite parts of teaching, it’s his mentorship of his Enterprise students, especially as they lead a substantial outreach program in ECE. Through Summer Youth Programs, Upward Bound and other programs, Archer’s team hosts hundreds of pre-college students annually. Glen says he ‘couldn’t be prouder’ of the work these teams are doing. He also cites a recent win and third place finish in international competitions for the Blue Marble Security team.

“Finally, Glen measures his success by ‘hearing from students that what they learned in EE3010 was useful in their senior design projects. That’s what helps me get up in the morning.'”

Fuhrmann says “I think that Glen is terrific, and I don’t know what I’d do without him.”

But given Archer’s student focus, perhaps the best endorsement in his unique teaching capacity comes from a Reddit.com review by an anonymous student. “I’m not an EE so I had him for circuits for non believers, and man is he funny. He is also super helpful. He sets up online help groups, encourages participation, suggests going to his hours, and suggests going to the help center. He’s a really good professor and teaches the material well.”

Archer will be recognized at an end-of-term luncheon with 11 other showcase members, and is now eligible for one of three new teaching awards to be given by the William G. Jackson Center for Teaching and Learning this summer recognizing introductory or large-class teaching, innovative or outside the classroom teaching methods, or work in curriculum and assessment.


High Resolution ToA Estimation via Optimal Waveform Design

ToA PaperThis paper introduces a novel method to improve the Time of Arrival (ToA) estimation resolution for a fixed available bandwidth in the presence of unknown multipath frequency selective (MPFS) channels. Significant desire on utilized bandwidth reduction in wireless technologies endorses exploiting this technique to increase ranging resolution and/or time synchronization while low bandwidth signal are exploited. Exploiting this method would have extensive impact on variety of technologies which enjoys ToA as ranging technique such as radar, wireless communications and etc.

Fridays with Fuhrmann: A Movie Pick

(Photo: Hollywood Reporter)

A few weeks ago my family and I went to see “Hidden Figures.” This movie traces the story of three African-American women in their struggle for opportunity and recognition as mathematicians and engineers in the early days of NASA’s Mercury space program. The story takes place in a time when NASA employed a large number of “computers” which in those days meant, literally, “people who compute.” Taraji P. Henson plays Katherine (Goble) Johnson, a mathematician who calculated spacecraft flight trajectories and ultimately played a critical role in the success of the John Glenn’s pioneering flight, orbiting the Earth – all while battling an organization that refused to give credit for her contributions, and having to walk a half mile in heels to the “colored” bathroom. Janelle Monae plays Mary Jackson, an aspiring engineer who identifies a problem with the capsule’s heat shield, and who eventually goes on to a career as an aeronautical engineer and engineering manager at NASA. Octavia Spencer plays Dorothy Vaughan, the unofficial supervisor for a group of female African-American “computers” who fought for recognition as a real supervisor and, after learning FORTRAN and becoming familiar with the new IBM computers that were installed to replace their human counterparts, eventually became supervisor of the Programming Department. I found the movie engaging and entertaining, and recommend it highly.

Even before seeing this, from the trailers it brought to mind two other movies about people struggling to make their contributions in the face of overt discrimination. One was “42”, the story of Jackie Robinson of the Brooklyn Dodgers, the first African-American in Major League Baseball. I was mildly disappointed in this movie. Of course the historical story line is compelling, and the movie was well-acted and well-directed, but there were no surprises. The story arc was a straight line from beginning to end and most of the action was pretty predictable, especially to those with a cursory knowledge of baseball. The screenplay practically wrote itself.

I was even more disappointed in “The Imitation Game”, about Alan Turing, the brilliant mathematician and essentially the founder of modern computer science, who played a central role in the decrypting Nazi intelligence codes for the British in World War II. After the war Turing was outed for being gay, prosecuted for “gross indecency”, and eventually committed suicide in 1954 at age 41. Again, the movie was very well made and was a commercial success. However, it had quite a number of historical inaccuracies which distort his relationships both during and after the war. At least, that is what I have read – this is one of those cases where everything I know I learned on the Internet. What I have read, however, is consistent with the way I felt after seeing the movie. Somehow it did not ring true, that the filmmakers were trying too hard to portray historical events in the context of modern sensibilities. (My mother, who is something of a Civil War history buff, felt the exact same way about Steven Spielberg’s “Lincoln.”)

So, going into “Hidden Figures” I was prepared for an entertaining but not particularly deep piece of fluff. I couldn’t have been more wrong. I was completely pulled in to the story of these three women, and the juxtaposition of something that I cannot identify with (the struggles of African-American women) with something that I can (engineering and mathematics). Granted, there are parts of the history that are slightly altered for dramatic effect, but that is to be expected in any docudrama. I have not read any major complaints about historical inaccuracy. Katherine Johnson did go on to be awarded the Presidential Medal of Freedom in 2015, was married 50 years to the soldier who courted her during the Mercury program (also depicted in the movie) and has a building named after her at Langley Research Center. Mary Jackson became NASA’s first black female engineer. Their story reflects the stories of countless other women and African-Americans who are pioneers in the STEM fields, blazing a trail for the modern generation of students and STEM professionals. I left the theater inspired and proud to be an engineer.

In addition to the central story line of the movie, there were two other messages that I absolutely loved. One is that an engineering education is something worth fighting for. For me the most moving scene in the movie was when Mary Jackson went before a judge and made her case, successfully, for why she should be allowed to take University of Virginia night-school engineering classes alongside the male students at all-white Hampton High School. Of course, these days no one should have to fight to be allowed to study engineering. The doors of Michigan Tech, like those of all engineering schools in the United States, are open to those who have prepared themselves and are willing to work hard. We can be proud of that, but we also have to recognize it would not be true without the efforts of many like those depicted in this movie.

The other message that I appreciated was one that had nothing to do with the social context, but was about engineering in general and the importance of getting things right the first time. When the flight engineers are determining the exact point in John Glenn’s flight when he goes from an elliptical orbit to the parabolic trajectory that will bring him back to the Earth – the “go/no-go” point – Katherine is pulled in to make sure that the calculations are absolutely correct. It brought to mind Ed Harris’ famous admonition in “Apollo 13” – failure is not an option! Any errors in the calculation would have meant a failure of the mission and the loss of an American hero. I was really happy to see that little message in there, and I hope all the budding engineers and mathematicians in the audience were paying attention.

Bottom line – wonderful movie; any STEM students (meaning 85% of Michigan Tech) would get a kick out of it. Two thumbs up!
