The presentations were as follows: “Detection of multi-scale secondary flow structures using anisotropic 2D Ricker wavelets in a bent tube model for curved arteries,” “Perturbation-induced secondary flow structures due to fractured stents in arterial curvatures” “A regime map for secondary flow structures under physiological and multi-harmonic inflow through a bent tube model for curved arteries,” and "Three-Dimensional Flow Separation Induced by a Model Vocal Fold Polyp." Prof. Plesniak is a member of the Nominating Committee and also serves on the Division of Fluid Dynamics Executive Committee, which held its annual business meeting during the conference.

Tejas Ruparel (CEE graduate student), Prof. Azim Eskandarian (CEE), and Prof. James Lee (MAE) presented their paper, “Multiple Grid and Multiple Time-scale (MGMT) Simulations in Continuum Mechanics,” at the 2012 ASME International Mechanical Engineering Congress and Exposition, held November 9-15 in Houston, TX. The paper was selected by the ASME Applied Mechanics Division and awarded second place in the Best Student Paper Competition.

Other News:

Prof. Howie Huang’s (ECE) research, "Pay as You Go in the Cloud: One Watt at a Time," won the ACM Undergraduate Student Research Competition at Supercomputing conference (SC'12) last week. In this work, Prof. Huang and Kayo Teramoto propose a pay-as-you-go per-watt-hour pricing model for cloud computing, where pricing becomes a more accurate cost estimate of the service received by the customers, and cloud computing providers’ profit can become more stable. Kayo, currently a sophomore at Yale, did this work in Prof. Huang’s lab last summer. Prof. Huang and Kayo have been invited to the Grand Finals next year.

Prof. Rumana Riffat (CEE and associate dean for academic affairs) received two GW Service Excellence Awards in the Collaborative Initiative category at the university’s November 15 Service Excellence Celebration. One award was for the Sustainability 1001 Team, where faculty from five schools worked together to develop and team-teach SUST 1001, the introductory course in the new sustainability minor. The group was praised for exemplary teamwork, learning, and collaboration. The other award was for the Clinton Global Initiative University at GW, where a large group of faculty, staff, and students worked together successfully to arrange and hold the event at GW.

The GW Institute for Nanotechnology is pleased to announce that Profs. Lijie Grace Zhang (MAE) and Joseph O'Brien (professor of orthopedic surgery) have won its 2012-2013 Interdisciplinary Research Grant for “Development of an innovative nerve graft via nanotechnology for spinal cord injury treatment.”

Guest Vignette:

With the reelection of President Obama, it is certain that the U.S. will be accelerating its recent push towards the development of all types of renewable energy sources. This rapid growth mirrors that of the environmental and energy management (EEM) concentration in EMSE, in conjunction with other academic programs throughout SEAS and GW.

EEM doctoral students such as Steven Burns, Iryna Payosova and Mohammad Al-Jawah are actively engaged in cutting-edge research in the middle of this rapidly expanding area, complementing state-of-the-art courses taught by leading energy expert adjunct faculty such as Dr. Elvin Yuzugullu of the SRA Corporation, Dr. Rachael Jonassen of LMI and Dr. Jim Galvin of the National Renewable Energy Laboratory. Many EMSE graduates who have achieved substantial positions in renewable energy areas, such as Ariel Castillo with the Department of Defense and Laura Verduzco of the Chevron Corporation, have chosen to stay actively engaged with the EEM program, adding an important set of benefits to her current students.

While a complete listing of ancillary EMSE energy activities would be too long to include here, examples include the new joint EMSE/MAE Energy Engineering and Management certificate program, participation in monthly meetings go the "solar salon" group organized by the Energy and Environment Study Institute, involvement in the recent DOD "Next Generation Energy Technology" symposium, association with GW's new undergraduate minor in sustainability, external sponsorship of energy related research, conference presentations, and so on. While the energy challenges of the U.S. are great, the opportunities created by those challenges are also great, and the faculty and students of the EMSE and our colleagues throughout SEAS are fortunate to be in the forefront in this extremely important and challenging area.
