Mechanical Engineering Research

• ENEMY DETECTION
• A new sensor that measures the motion created by
  sound waves under water could allow the U.S. Navy
  to develop compact arrays to detect the presence
  of enemy submarines.
• These compact arrays would detect quiet
  underwater targets, while providing very clear
  directional information.

• The novel underwater sensor uses optical fibers
  to detect the direction from which a sound is
  coming under water.
• This directional component is an important
  improvement over the current technology.

16
Mechanical Engineering Research

• MATERIALS MAY SOON AID ORTHOPEDIC SURGERY
• Motivation To develop devices that may soon
  improve the treatment of human orthopedic
  conditions.
• Details

• The research focuses on shape-memory polymers
  and alloys solid materials that can change shape
  on demand.
• The ability of these materials to mold actively
  to human bone and tissue will make them useful in
  reconstructive surgery.
• Examples of the product applications are for use
  in knee surgery and those with diabetes who
  develop ankle pain.

17
Mechanical Engineering Research

• ACTIVE CONTROL OF AUTOMOTIVE DISC BRAKE SQUEAL
• Objective To investigate the use of dither
  control (intentionally applied noise) for the
  suppression of automotive disk brake squeal for
  GM.
• Overview Theoretical and experimental models
  are being used to develop an improved
  comprehension of the dynamics involved.

• Experimental Setup The experimental set-up
  (using a brake dynamometer) measures braking
  pressure, brake pad temperature, the normal force
  on the brake pads, braking torque, in-plane
  velocity of brake pads and rotor and acoustic
  measures with a microphone.

18
Mechanical Engineering Research

• NON-INVASEIVE TESTING FOR OSTEOPOROSIS
• Objective To further develop a non-invasive
  technique for analyzing and reporting microdamage
  in the trabecular bone the region most affected
  by osteoporosis.
• Motivation The trabecular bone serves as the
  shock absorber for human joints. Also, severe
  osteoporosis can be extremely painful and costly.
  
• Method To assess the acoustic emission from the
  trabecular bone by simultaneously acquire
  acoustic emission and stress/strain data.
• The trabeculuar bone specimens used in the
  experiment were extracted from bovine femurs.

Alumni Profile

• Alison, BSME Summer 2008
• Currently at Grad School at Stanford

Undergraduate Research at GT I worked in a
tissue engineering research lab on working
towards building an artificial blood vessel that
could be implemented into the human body. The
first part was to understand the tissues that
already exist in the body (in particular,
collagen) and how the tissue grows and remodels
under stress change.

  (President)
• Freshman Activities Board
• GT Swimming and Diving
• Search Committee to find new ME School Chair
• ME School Undergraduate Curriculum Committee.
• Won a school spirit scholarship in my junior
  year.
• I would like to stress that I got involved in my
  major more than the school (like school-wide
  spirit organizations) and that that worked out
  best for me.

• Future Goals
• MSME _at_ Stanford with a focus in
  Biomechanics.
• I want to invent a medical device and start a
  company.
• However, I plan to work with a medical device
  company first.

• Advice to Students
• You dont have to know what you want to do with
  the rest of your life when you're 17!
• Look into all your options and start out studying
  something as broad as you can (for example, I
  liked science and math and chose ME).
• If you want/need advice on a career choice, don't
  be afraid to ask someone to talk about what they
  do! You'll be surprised to see how nice people
  are if you are kind in return.
