Greetings! It seems the older I get the faster the years
fly by, and this year was no exception. It's been a
privilege to serve as the chair of the IEEE Pittsburgh
Section in 2015, and next month I'll be handing over the
reins to our incoming chair for 2016, Jim Lagree.
Looking back, there was a lot accomplished we can all
take pride in. Thanks to Xin Li and a number of faculty
members at CMU and Drexel, we founded a new
chapter of the Council for Electronic Design
Automation (CEDA). This is our very first council, and
our first chapter to span multiple IEEE sections. Many
thanks to Xin and his colleagues for pulling this
off. We're also very proud of our existing
chapters. Congratulations to Kal Sen, chair of PELS,
which was named the outstanding PELS chapter of the
year. Congratulations also to Dave Vaglia, chair of
PES/IAS, which received a PES high performing
chapter award.
We had so many great technical seminars this year I
can't possibly acknowledge them all. Thanks to Steve
Dobos, we had a memorable trip to the WQED studios
and the transmission tower atop Oakland. Thanks to
Joe Kalasky, we got a behind the scenes glimpse of the
casino operations at Nemacolin and all the associated
technology we were never aware of. And Joe Cioletti
brought together IEEE leaders, the Pittsburgh
technology council and the PA bar association to
discuss changes to intellectual property law. Thanks go
out to all the chapter chairs for organizing so many
worthwhile events in 2015!
Along the way, we recruited some new volunteers and
we even created a new position on our executive
committee -- student section representative -- to foster a
closer relationship with the student chapters. Thanks
go out to our new volunteers: Brandon Contino, Blaine
Headley, Paige Kassalen, Matt Rehder and Jun Yang,
as well as the rest of our dedicated volunteers that keep
our section going.

Beck’s Bytes – Continued
Thanks to Tom Dionise, we also continued our tradition of support for STEM and the local community,
with our IndEEE 500 robotic car race at the Carnegie Science Center during Engineers week. Tom also
served as our lead judge at the 2015 Intel International Science and Engineering Fair (ISEF) which was
hosted in Pittsburgh this year. IEEE sponsors a $10,000 scholarship, and we were privileged to put
together a judging team and select an outstanding recipient: Alex Tacescu. Many thanks to Tom and all
the volunteers who put in many hours to support this event.
We also had the privilege of representing Pittsburgh at a number of meetings throughout the year. I
attended the annual R2 meeting in Columbus along with Joe Kalasky, Bob Brooks and Ralph Sprang,
and I also attended the annual meeting with our sister section in Toronto. Joe Cioletti represented us at
an IEEE congressional fly-in event in Washington DC, Jim Lagree and Bob Brooks represented us at the
annual IEEE USA conference in Milwaukee, and Paige Kassalen participated in the WIE Summit USA
East in Philly.
Last but not least, we had a little fun, and carried on some worthwhile traditions like our annual history
& awards dinner, where we honored our newly elevated IEEE fellows and 50th anniversary recipients,
and also our annual picnic. Many thanks to Kal and Mey Sen, Steve Mozelewski, Dave Vaglia, Matt
Rehder and Lou Hart for organizing these events.
While I have the privilege of reporting these accomplishments, I can't claim credit for them. I'm
indebted to a diverse and dedicated group of volunteers that keep our section going. In particular, I'd
like to thank my fellow section officers, Jim Lagree, Drew Lowery, Navid Binesh and Dan Wilson for
doing a fantastic job this year, along with our bulletin editor Phil Cox and webmaster Gerry
Kumnik. Thanks also go out to Steve Mozelewski for organizing our senior member drive, and our past
chair Lou Hart for leading the nomination committee and always giving me good advice. Last but not
least, I'm indebted to our members at large for your help and support, and for making my term as section
chair an enjoyable and rewarding experience.
Thanks, have a wonderful holiday, and best of luck in 2016!

Organizer: Power Electronics Society (PELS) Chapter and Joint PES/IAS Chapter
Abstract: The power industry’s pressing need for the most economical ways to transfer bulk power
along a desired path may be met by building new transmission lines, which is a costly and longer
process. Alternately, it may be cheaper and quicker to utilize the existing transmission lines more
efficiently. The key is to identify the underutilized transmission lines and harness their dormant capacity
to increase the power flows to the lines’ thermal limits.
Power flow control techniques have been practiced, from using inductors, capacitors, and breakers in the
earlier days of electrical engineering to power electronics-based solutions in recent years. Even though
the costs of the available solutions vary widely, the basic underlying theory of power flow control is still
the same as it always has been. The question is which solution one should employ. The answer depends
on knowing what the true need is.
Since the commissioning of the first commercial power electronics-based Flexible Alternating Current
Transmission Systems (FACTS) controller two decades ago, a great deal has been learned about the true
needs of a utility for its everyday use and they are high reliability, high efficiency, low-cost, component
non-obsolescence, high power density, interoperability and portability while providing the optimal
power flow control capability. This was the motivation to develop a SMART Power Flow Controller
(SPFC) that enhances the controllability in an electric power transmission system by using functional
requirements and cost-effective solutions. Utilities that are looking for ways to enhance the
controllability in their power grid by voltage regulation, phase angle regulation, line impedance
regulation, fault-current limitation, and much more should consider using a SPFC.
The presentation is designed to provide the basic principles of power flow control theory, an overview
of the most commonly used power flow controllers, and future trends. The presentation will be of
particular interest to all utility power engineering professionals. The required background is an
equivalent of an electrical engineering degree with familiarity in power engineering terminology. The
audience will hear from an expert who actually designed and commissioned a number of power
electronics-based FACTS controllers since its inception in the 1990s.
IEEE Pittsburgh Section Bulletin December 2015 Volume 64 No. 12 Page 5 of 12

HackPGH's Autonomous Power Wheels Racing Series Car
The Pittsburgh section of IEEE Robotics and Automation Society presents a technical session about
HackPGH's designing, building, and racing an Autonomous vehicle based on a Power Wheels toy.
Meeting will be held at the HackPGH shop 1937 Watson Street, Pittsburgh, PA 15219 starting at 6:30
PM on 14 December 2015. Pizza/sandwiches will be provided. Please register for this meeting at
meetings.vtools.ieee.org/meeting_view/list_meeting/37175 or send an email to [email protected].
In September 2015, HackPittsburgh entered in the first ever autonomous racing division of the Power
Racing Series (http://www.powerracingseries.org/) at World Maker Faire in New York city. The power
racing series challenges entrants to build ridiculously cheap, ridiculously small race cars based on
children's Power Wheels ride-on cars, then -until now- cram a full sized adult in the drive seat. This
presentation will explain their build-from-scratch, self-driving car and the technology behind it.
The car borrows its drive train from a wheel chair and fuses information from a laser scanner, an inertial
measurement unit (IMU), and wheel encoders to generate a map of the racetrack by means of a
simultaneous localization and mapping algorithm. It then navigates through the established map while
autonomously estimating the relative position within the map. The free, open-source, and community
driven Robot Operating System (ROS) has been used as the underlying software platform and most
software packages that were used for this project are freely available on the internet, making
autonomous robots accessible to anyone.
HackPittsburgh (www.hackpgh.org) is a non-profit community-based workshop that allows members to
come together and share skills and tools to pursue creative projects.

“Return To the WQED Tower“ The IEEE Pittsburgh IAS/PES Joint Chapters completed a very successful “Return To the WQED Tower“ antenna tour this past October 22
nd, 2015. Thank you to all that attended. We had a great turn out of
approximately 24 to 26 attendees. About 6 to 8 were students, 2 professors: 1-Carnegie Mellon, 1-University of
Pittsburgh.
To start off things, a very positive Meet and Eat was held on top of the Peterson Events Center parking garage beforehand. Great views of the Pittsburgh Skyline were had by all. Lots of good interaction (social networking)
between the students and the established IEEE personnel.
As the Meet and Eat was wrapping up, preparation for the antenna part of the tour began. The tour preparation
included handing out the brand new audio receivers with headphones to all the members. One audio transmitter
was handed out to our tour presenter Mr. Paul Byers (Executive Director of WQED Engineering).
The audio equipment was used in conjunction with the tour to promote clear communication between the presenter and participants. Upon touring this facility last July, there was no audio equipment and we ran into a
problem with communication. It was a noisy environment and all participants could not hear all the
communication being presented. This audio equipment was purchased by our section and it performed beautifully!
Our WQED tour presenter “Paul Byers – Executive Director of WQED Engineering” started off the Antenna tour
by having us look up at the antenna (pictured above) as he proceeded to explain the attached equipment lining each side of the antenna all the way to the top!
IEEE Pittsburgh Section Bulletin December 2015 Volume 64 No. 12 Page 10 of 12
The Next part of the tour included taking everyone into and through the two story brick building housing the
transmitter (and some receiver) hardware. Multiple rows of new digital cabinets can be seen below alongside of the old analog cabinets as they hum along broadcasting TV and Radio signals over Pittsburgh...
The WQED Antenna tour ended up as a very successful gathering for our younger members as well as
our older members. Our presenter was extremely knowledgeable and we could not have asked for a
better host!
