Aerospace Engineering

Academic Guidance, Navigation, and Control Research and the Evolution of the Unmanned Aerial System: Make it Work, Change the World, Repeat


Monday, April 24, 2017; 11:15 am - 12:05 pm
158 Willard Building
Speaker: Dr. Eric Johnson from Georgia Institute of Technology

Abstract: The evolution of Unmanned Aircraft Systems (UAS) over the most recent 20 years has seen an impressive rate of innovation.  The time between a new technology first appearing in academia and being available in a consumer product can be very short compared to the rest of the aerospace industry.  Throughout this period, the navigation, guidance, and control challenges in UAS have been among the most significant barriers to wider use.  That remains true today.  This talk will reflect upon past work at Draper and Georgia Tech, and lessons learned about which technologies have “made it” and perhaps why.  Specific highlights include  one of the first small GPS-navigated helicopters, fault-tolerant control results, and the automatic transition of an airplane to/from tail-sitting hover.  Later work includes sensing and avoiding other aircraft and obstacles, navigation without reliance on Global Positioning Satellite systems (GPS), and multi-aircraft cooperative autonomy.  This will include progress in both theory and related flight test validation.  The talk will conclude with some speculation about the next “wave” of UAS guidance, navigation, and control theory and technology that will be significant – and perhaps where academic research can best contribute. Bio: Eric Johnson is the Lockheed Martin Professor of Avionics Integration, School of Aerospace Engineering, Georgia Tech.  He received a B.S. degree from University of Washington, M.S. degrees from MIT and The George Washington University, and a Ph.D. from Georgia Tech, all in Aerospace Engineering.  He also has five years of industry experience working at Lockheed Martin and Draper.  As Georgia Tech faculty since 2001, he has performed research in unmanned aircraft fault-tolerant control, aided inertial navigation, and autonomy.  This work has included the first air-launch of a hovering aircraft, automatic flight of a helicopter with simulated frozen actuators, and vision-based air-to-air tracking.  His most recent work has included automatic low altitude high speed flight of helicopters, indoor and outdoor vision-aided inertial navigation, and methods for sensing and avoiding other aircraft.  The mission of this work has been to enable unmanned aircraft systems to contribute to society.

Biomedical Engineering

Addressing Delivery Challenges through Controlled Materials Design


Thursday, April 27, 2017; 12:05 PM - 1:20 PM
135 Reber Building
Speaker: Dr. Jianjun Cheng from Illinois at Urbana-Champaign

Controlled materials design and synthesis play a significant role in addressing various drug delivery challenges in vitro and in vivo. In this seminar, I will present our work on the development ionic helical polypeptides capable of mediating efficient membrane penetration, addressing cellular trafficking challenges.  I will also describe our work on silica nanomedicine and size controlled nanomedicine in tumor penetration and identification of optimal size of nanomedicine in cancer therapy. Finally, I will present sugar molecular mediated in vivo cancer targeting.  We successfully developed azido-sugar derivatives that can label triple negative breast cancer and enable successful in vivo targeting.

Chemical Engineering

The Reversible Nature of Sulfur Poisoning in Automotive Catalysis


Thursday, April 27, 2017; 9:30 - 10:30 am
102 Chemistry
Speaker: William S. Epling from University of Virginia

The Reversible Nature of Sulfur Poisoning in Automotive Catalysis

Hosted by: Lisa Haines,  Chemical Engineering  (lhaines@engr.psu.edu)

Mechanical and Nuclear Engineering

Self-Contained Hydraulic "Nastic" Actuators


Monday, April 24, 2017; 4:00 - 5:00 pm
26 Hosler Building
Speaker: Elisabeth Smela from University of Maryland

Artificial muscles typically deliver either large displacements or high forces, but not both.  This talk will introduce hydraulic actuators that take advantage of a micro-scale phenomenon, electro-osmotic fluid pumping.  This approach may make it possible to create a new type of electroactive polymer device that is self-contained and electrically actuated.  Flexible devices can be fabricated by laminating together layers of paper and elastomer and encapsulating a pumping fluid – propylene carbonate – that does not generate gas bubbles.  Biomedical applications such as smart stents with adjustable diameters are being pursued, as well as use in small, soft autonomous robots.

School of Engineering Design, Technology and Professional Programs

HESE, A Vision for Scale


Wednesday, April 26, 2017; 10:45 AM - 11:45 AM
307 Hammond Building
Speaker: John Gershenson from Michigan Technological University

ABSTRACT: Gershenson will present a vision for the HESE program that focuses on scaling the impact of the program across campus to create more opportunities for students and faculty to interact with HESE. The vision is a HESE program that retains the rigorous venture development component at its core, but seeks to reach out to every program on campus to create collaborations and offer more ways for more people to participate in the HESE program on their own terms. BIO: Gershenson is a professor of mechanical engineering at Technological University and has served as co-coordinator Michigan Tech’s Peace Corps Masters International program in Mechanical Engineering and as a Fulbright scholar in Kenya. He has taught human-centered design and social entrepreneurship, and practiced it as CEO of his own start up company in Kenya. His current research is focused on 3D printing for humanitarian relief and rural medical facilities.
