In the Spring Semester of 2013, a
group of students enrolled in the
ENGR 4983 International Engineering
Experience—Australia. Several LETU
students, along with civil engineering
professor Dr. Stephen Ayers, traveled
to Brisbane, Toowoomba, Carnarvon
Gorge, Emerald, Blackwater, Mt. Morgan, Yeppoon, Hervey Bay, Sunshine
Coast, and Sydney, Australia during the
20-day trip.
They first flew into Brisbane, which is
the capital city of Queensland to experience Australian life in a large city.
While there they visited the Brisbane
Airport, Gateway Bridge, a motor
construction project, the Brisbane
traffic control center, a water treatment plant, and various other sites. In
Faculty Abroad
Dr. Ayers’ hometown, of Toowoomba, they toured the University of Southern Queensland, a
startup company that develops fiber
composite products for construction, and a mining equipment manufacturer. From Toowoomba, the
students and Dr. Ayers backpacked
through the Australian Outback
visiting the Carnarvon Gorge National Park, the town of Emerald,
and the BHP-Mitsubishi coal mine in
Blackwater. After the Outback,
they went snorkeling at the Great
Barrier Reef and chartered a private yacht. From here, they
stopped at Hervey Bay and the
Sunshine Coast near Brisbane. After
the coast, they ended their trip by
traveling to Sydney for a tour of the
harbor, Opera House, and Sydney Harbour Bridge.
The locations were chosen to provide
exposure to a wide range of engineering
projects and local culture. The aim was
to combine understanding of how engineering work is done differently in Australia in the context of a different societal setting. It also provided practical
experience with issues Dr. Ayers spent
the semester, prior to the trip, discussing in class. “The trip takes them out of
the box they live in. It’s something different.”, said Ayers, “Its important that
they learn that different is not a value
judgment. Everything is done for a reason, and sometimes you have to understand the reason for the differences.”
LETU Student Competition—4 Winners
LETU students placed at or
near the top in four big competitions last year.
First place winners, Alex Rickards

LeTourneau University students.
The LARC Robotics team of
Jonathan Sculley (team lead),
Evan Jones, Jordan Swavely,
William Warke, Leila Yammine, Peter Heitmann, and
Bryan Swink took first place in
the IEEE Region V Robotics competition against 26 other teams. The
competition involved simulating the
safe extinguishing of an oil rig fire.
Challenges included navigation
through the wooden “waves,” object
detection, and object manipulation.
At the same student conference,
seniors Ben Ito and Alex Rickards
won first place in the Region V
Circuit Design Competition against
18 other teams.
Stephen Wood of Longview, Texas
won second place in the 2013 IEEE
Metro-Con Undergraduate Student
Poster Competition. Stephen was
presenting a poster on the 20112013 High Frequency Antenna
Coupler (HFAC) senior design
project, which was the focus of an
electrical and computer engineering capstone course under the
direction of faculty sponsor Dr.
Joonwan Kim, who also sponsored
Stephen at the poster competition.
The High Frequency Antenna Coupler (HFAC) design project featured in Wood’s poster was a senior design team project in partnership with Rockwell Collins Inc.
Last October, an LETU team took
third place in the nation and 34th
place internationally in the IEEE
Extreme Programming Competition, a 24-hour (7 PM to 7PM) programming contest.

LETU Professor Awarded NSF CAREER GRANT
A LeTourneau University project could make detecting cancer as easy as checking blood
glucose levels. For the past 10
years, Seung Kim, assistant
professor of electrical engineering, has been studying biosensor technology and its possible benefits in the fight against
cancer and other diseases. Kim
is working with senior engineering students to develop a
prototype for an affordable and
portable device that could recognize disease in its early stages. The device could be used anywhere. “It may be able to predict heart
attacks, too,” Kim said. Much like a
blood glucose monitor used by diabetics, early disease detection with the
biosensor would use blood analysis, he
said. Kim used prostate cancer as an
example of what the device could
identify. “A certain PSA (prostatespecific antigen) level could tell a patient his risk for that type of cancer,”
he said. “You can imagine if you have
that kind of device, you could prick
your finger and input that info into the
device. We are focusing on blood because the main information is there,
but it could use other bodily fluids in
the future.”
she and other senior biomedical
engineering majors started working on the 7-by-7-by-4 inch prototype in August and plan to have
it completed by the end of the
semester. “I think it would be
wonderful if we had an open and
available resource to help people
before they get really sick and
there is nothing that can be
done,” she said.
Senior Louis Trevino said the
biggest challenge in developing
the prototype has been preparing
slides to analyze the fluids. “We recently

Biomedical Engineering Society 2013 Conference
From September 26-28th, LeTourneau
University Biomedical Engineering students
and professor attended the annual Biomedical Engineering Society Conference in Seattle, Wash. At the conference, nearly
4,000 engineers, scientists, professors, students, and healthcare providers gathered
to learn and share the latest in biomedical
and bioengineering research and technologies. The conference featured hundreds of
poster sessions, platform presentations,
and industrial/academic exhibitors.
LeTourneau students were among a small
percentage of the undergraduate researchTHE

presenting their studies with posters entitled “Effect of Calcium Chloride in PlateletRich-Plasma on Platelet Aggregation via Biointerfaces” and “Study of Platelet Adhesion
using the Novel Dynamic Layer-by-Layer
Biointerface Construction.” Students gained
valuable experience in scientific presenting,
learned about exciting technologies, and
were afforded networking opportunities.
They also got the opportunity to experience
Seattle. The conference was located in the
heart of the city, and students were able to
explore the caffeine-fueled city. Highlights
included visiting the first Starbucks,
visiting the Space Needle, going to the Public Market,
and eating along the Waterfront. Senior BME student,
Alex Rhyner, said, “There were several interesting
talks, and Seattle was beautiful. I learned a lot from
the conference, and I hope people learned from us
too!”

LETU Guinness World Record
Guinness World Record Holders
LeTourneau University claimed a Guinness
World Record on Friday, April 4, when
LETU engineering students set the record for
the greatest number of 3D printers running
simultaneously.
Only seven of the 109 3D printers that competed in the event did not work, resulting in
the world record number of 102, as confirmed by a panel of independent witnesses.
The students used their 3D printers to make
a gear-shaped coin to commemorate the
world record attempt.

Keck Wheels Grant
LeTourneau University researchers won a $250,000 grant from the W.M. Keck Foundation at the start of 2014 to expand research
related to human mobility and integrate that research into related courses. Assistant professor Norman Reese collaborated with
biology and kinesiology departments to submit the grant proposal in a year-long process. The collaboration is defined as the Interdisciplinary Mobility Lab.
The grant is providing funding for expanding research related to understanding the effort required to propel various wheelchairs
and improving wheelchair test methods. The studies will take place on the LeTourneau campus and various international sites. One
of the major purchases made possible by the grant is an instrumented wheelchair wheel that wirelessly communicates the force the
user exerts on the hand rim and the resulting acceleration of the chair. This device, as well s various load cells, instrumented gait
mats, and oxygen calorimeters, will also be used to demonstrate various principles in classes such as physics, dynamics, engineering
design methods, biology, and kinesiology courses. Along with advancing LeTourneau’s research capabilities, the goal of the grant is
to increase student learning by showing how course concepts can be used for real-life humanitarian applications.

The Department Chair’s Message
MESSAGE FROM THE CHAIR
I always enjoy a thought-provoking
discussion. One of the key discussions
that came out of our faculty workshop
this fall centered on the question:
“Where do we each fit in God’s grand
story?”
The specific wording was linked to one
of our University Goals:
“LeTourneau University educates
students who…integrate Christian
faith and work: understanding their
vocation within the triune God’s
grand story of redemption revealed in
Scripture.”
The “grand narrative” is the history of
the world in four parts—Creation, Fall,
Redemption, and Restoration. As
Christian engineers, we have the privilege of both pointing people to Christ
our Savior and participating with God
in the restoration of a fallen, broken
world. Providing clean water, safe
structures, effective communication,
and devices that restore damaged
limbs are all part of that restoration.
Our goal is to educate the next generation of engineers who will positively
THE
R.G.
ENGINEER
impact their workplace and world
with this mindset.
Some things look a lot different
from when I came 35 years ago.
Students with 3-D printers, Arduinos, and Lego Mindstorms can fabricate amazing designs.
We are hitting several “soft”
skills—teamwork, project planning,
and communication—as well as solid technical skills. Now,18% of our
engineering students are female.
We are a truly global student body,
with multiple students from Korea,
Brazil, African nations, Saudi Arabia,
and Latin America. Our basic mission hasn’t changed.
As I write this in late October we
have just completed another ABET
(accreditation ) visit, and we're
thankful for the experience. Back in
July we submitted a Self-Study
report that ran 100 pages, with an
additional 900 pages of supporting
documentation. Looking back over
all of the course and lab material I
am reminded again of what a great
team we have here and how the
Lord has blessed this program.
