model outlines a framework
for considering:
* The attacker's skill level and motivation
* The vulnerable vehicle system components
* The ways in which an attack could be achieved
* The repercussions, including for privacy, safety and financial loss
While every new generation of auto tech brings new security risks,
the vulnerabilities that come along with advanced mobility are both
unprecedented and under-studied, the paper states. The tool is believed
to be the first of its kind focused on automated vehicles. Mcity, led
by U-M, is the nation's largest public-private partnership working to
advance connected and automated mobility.

The 2018 NASA Breakthrough, Innovative and GameChanging (BIG) Idea Challenge supports development
of innovative and high-impact technologies for use in
a broad array of future NASA missions. The challenge
allows students to incorporate their coursework into
real aerospace design concepts and work together in a
team environment. This year's challenge is to develop
solar panels for a future Mars mission, where supplying
reliable electric power for humans on the Martian surface
is a critical technology need. The five finalists in the
challenge are Norwich University, Princeton University,
Texas A&M University, University of Colorado-Boulder
and University of Virginia. The 2018 BIG Idea Forum is
scheduled for March 6, 2018, at NASA's Glenn Research
Center in Cleveland.

The University of Cincinnati is
working with the U.S. military
and General Electric to find ways
to reduce jet noise, both to keep
the peace with airport neighbors
and to protect the health of
ground crews. Ephraim Gutmark,

engine nozzle has a large impact
on the amount of noise generated, and that's a specific area of study.
Some aircraft already use nozzle-shaping techniques, such as serrated
edges. UC is studying injecting small jets of air around the stream
coming from the jet nozzle, which has the same noise-damping effect as
the serrated edges on the nozzle.

CDS TEAMS CAN PAY IT FORWARD WITH
VOLUNTEER WORK IN THE CLASSROOM

Lawrence Technical University CDS members assist with Gravity
Cruisers at Emerson Elementary School. Gravity Cruisers is one of 11
A World in Motion curricula for students in grades K through 8.
Through the first half of this school year, SAE
International's Learn Twice Special Initiative has seen
more than 120 SAE Collegiate Design Series team
members from 18 schools volunteer over 500 hours in
classrooms using SAE's renowned A World In Motion
(AWIM) Challenges. More than 3400 students have
been impacted by the Learn Twice Initiative, and the
participating CDS teams have received over $40,000
in sponsorships or CDS registration reimbursements
for their efforts. "We had an amazing time teaching
Miss Phelan's after school STEAM program. It is an
experience that our team will never forget," said a team
member from Embry Riddle Aeronautical University.
An additional 80 CDS teams have expressed interest
in participating in the initiative this year and are either
volunteering in classrooms now or will participate later
this year. For more information, contact Ken Francis at
kenneith.francis@sae.org.
