Honors and Awards:

Prof. Ergun Simsek (ECE) has been selected to participate in the National Academy of Engineering’s (NAE) 2013 Frontiers of Engineering Education symposium, to be held October 27-30 in Irvine, CA.  The NAE selected 73 of the nation's most innovative, young engineering educators to participate in the symposium.  Those who were selected were nominated by fellow engineers or deans and chosen from a highly competitive pool of applicants.

Research:

Prof. Philippe Bardet (MAE) has received a three-year grant from the U.S. Department of Energy for the project “Validation Data for Depressurized and Pressurized Conduction Cooldown.”  It is a collaborative project with co-PIs at NASA Langley and Oregon State University.  The full value of the grant is $800,000, and the GW portion is $380,000.  Prof. Bardet and his colleagues will perform detailed velocity field measurements inside a large pressurized gas chamber that mimics advanced gas-cooled nuclear reactors during accident scenarios.  This will require adapting molecular tagging velocimetry to reactor conditions: high-temperature and high-pressure.  Experimental data will be used to validate CFD (computational fluid dynamics) models.

Prof. Jonathan Deason (EMSE) was awarded a three-month, $49,433 grant by the Potomac Electric Power Company to develop a smart energy consumer education curriculum and consumer research program on smart meter usage.  EMSE Visiting Scholar Joseph Cascio is working on the project with Prof. Deason, and EMSE graduate students Priya Swamy, Iryna Payosova, Junchao Gu, Soala Whyte and Benjamin Heras are participating in the project as research assistants.  The project offers potential for a subsequent longer term grant to implement the educational and research program to be developed under the award.  Prof. Deason is the principal investigator on the grant.

Media Mentions:

NewsChannel 8 interviewed Prof. Joseph Barbera (EMSE), the co-director of the Institute for Crisis, Disaster and Risk Management, on September 17 about the response to the Navy Yard shootings the previous day.

 

Publications:

Prof. David Broniatowski’s (EMSE) paper “Does Seating Location Impact Voting Behavior on Food and Drug Administration Advisory Committees?” was published in print in this month's issue of the American Journal of Therapeutics.

Prof. Ken Chong (MAE) recently published two journal papers: 1) K.P. Chong, X. Wang, and S-L Chong, “Translational research in sustainability and mechanics,” International Journal of Sustainable Materials and Structural Systems, Vol. 1, No. 2, pp.105–122; and 2) M.D. Kuruppu, Y.

Other News

The Institute for Biomedical Engineering is pleased to announce a call for proposals for the IBE Interdisciplinary Research Fund. This program awards up to $20,000 each for pilot projects leading to new extramural proposals.  The winner may apply for a renewal of another $20,000 at the conclusion of this award.  The deadline for response is 5:00 pm on Monday, October 7.

The Institute for Biomedical Engineering also announces the 2013-2014 Undergraduate Research Fellowship. This is an opportunity for undergraduates interested in conducting meaningful research in biomedical engineering and computing with a faculty mentor. The deadline to apply is Tuesday, October 15.

Over the summer, EMSE doctoral student Anna Noteboom worked with SEAS Computing Facility Director Raoul Gambian to turn used equipment from GW into opportunities for students at Hampton University.  Together, the two of them ensured that 43 old Sun workstations were stripped of information, reformatted, loaded with open source software, and made available for donation to Hampton University, a very good university located in Hampton, Virginia.  The computers will be used in the computer science curriculum to give additional hands-on learning and research opportunities to students.

Guest Vignette

Prof. Gabe Sibley directs the GW Robotics & Perception Group, which explores probabilistic perception algorithms and estimation theory that enable long-term autonomous operation of mobile robotic systems, particularly in unknown environments.  The group develops real-time localization and mapping systems, and is concerned with the fundamental understanding of sufficient statistics that can be used to represent the state of the world.  The Autonomous Robotics & Perception Group uses embodied robot systems equipped with a variety of sensors—including lasers, cameras, inertial sensors, etc.—to advance and validate algorithms and knowledge representations that are useful for robot navigation, planning and control. 

Prof. Sibley specializes in vision-based and inertial solutions to the “where problem”, which is perhaps best understood by reference to computer graphics: a CG movie like “Shrek” asks how a mathematical model of the world can produce a stream of images.  Prof. Sibley's lab does the exact opposite; it takes a stream of pictures captured by a robot and asks what model must exist to explain them?  This is a computationally intense estimation problem, often with millions of variables.  In real-time, we estimate both the sensor trajectory and the underlying 3D world structure.  (Provided courtesy of Prof. Gabriel Sibley of the Department of Computer Science)
