14. Research in Mechanical Engineering

15. Mechanical EngineeringAreas of Research • Acoustics and Dynamics • Automation and Mechatronics • Bioengineering • Computer Aided Design • Fluid Mechanics • Heat Transfer, Combustion and Energy Systems • Manufacturing • Mechanics of Materials • Microelectromechanical Systems (MEMS) • Tribology

16. 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.

17. Mechanical Engineering Research • MATERIALS THAT 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.

18. Mechanical Engineering Research DEVELOPMENT OF A KINEMATIC MODEL FOR A REHABILITATION ROBOT • There is currently no way to quantify how much a person with neuromuscular disorders shake. Shaking is the inability to modulate muscle patterns. • Objective: Develop a quantifiable test for people with neuromuscular disorders. • Patients will wear the robotic jacket and press a joystick in a prescribed way. • The jacket's actuators will then be turned off, one by one, to see how the muscle movements change. • This will isolate which muscles are most affected by the help of the jacket. • Different muscle groups and levels of shakiness vary with each type of ailment. • Ultimately the goal is to diagnose different neuromuscular ailments with this testing.

29. Senior Design – Case Study 4 • Precision Immobilization Technique (PIT) • PIT is the use of physical force from the police vehicle to the target vehicle with the intention to stop the target car • Problems with PIT • Potential collision with bystanders • Potential Roll over of the target car • Design Project Objectives • Prove the PIT maneuver does not cause rollover when performed under the proper conditions • Prove the PIT maneuver is a controllable when executed properly • Compare both experimental and theoretical results • Design and build an apparatus to experimentally measure the force applied from the police car onto the target car • Model the PIT in MSC Adams Software

French Bldg, Suite 104 during FASET days (excluding Sundays)

38. BS/MS Program TOMMY NEWTON BSME 2006, MSME 2008Application EngineerAccuSentry, Inc. The best part about the BS/MS program is that I was able to take a "test drive" before committing.  By the time I officially became a graduate student, I had performed undergraduate research with my advisor (Dr. ShreyesMelkote) for almost a year- and-a-half.  I was even able to spend a semester working on what would become my master's thesis topic. Taking graduate level classes as an undergraduate allowed me to get a feel for what the course work would be like. • Application Requirements: • Apply between 30 – 75 credit hours • Minimum GT GPA of 3.5 to apply • Advantages: • Allows students to take 6 hours of graduate classes their senior year, which count towards both the Bachelor’s (BS) & Master’s (MS) degrees • Students are not required to take GRE for admission to graduate school at Georgia Tech • Students who select the non-thesis MS option can usually finish in ~3 semesters beyond BS degree

39. Undergraduate Research • What is Undergraduate Research? • Undergraduate research is a single or multiple semester project working with a professor his/her research or special project • Research Requirements • Students can be paid or receive class credit towards the BSME • Students are responsible for finding faculty members to sponsor the research • Most research opportunities exist for juniors & seniors • 190 ME undergraduate research assignments were completed last year (Summer 2009, Fall 2009 and Spring 2010)

40. Co-operative & Internship Programs

41. Whether selecting co-op or internships, we strongly recommend every student to have work experience before graduation; two semesters is the optimum.
