Week of October 19 – October 25, 2009
Faculty News
RESEARCH:
Prof. Yongsheng Leng (MAE) recently obtained a new research grant of $100,000 from the American Chemical Society (ACS) Petroleum Research Fund (PRF). The project, “Structure and dynamics of aqueous and aqueous-hydrocarbon fluids between charged surfaces,” will study the fundamental mechanisms of clay swelling that widely exists in the petroleum industry. This grant will provide two years of support for a new Ph.D. student to get training in the field of computational materials science and molecular modeling.
PAPERS:
Prof. Charles Garris (MAE) has co-authored a paper selected for the 2008 Best Paper Award by the Advanced Energy Systems Division Heat Pump Technical Committee. The title of the paper is “Evaluation of Efficiency in Compressible Flow Ejectors” by Bulusu, K., Gould, D. M., Garris, C. A. The paper was presented at the Advanced Energy Systems Symposium, ASME International Mechanical Engineering Conference, October 31st - November 6th in Boston, MA.
CONFERENCES & PRESENTATIONS:
Prof. Pinhas Ben-Tzvi (MAE) presented a proceedings paper, "Experimental Validation of a Hybrid Mobile Robot Mechanism with Interchangeable Locomotion and Manipulation," at the 2009 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS2009), in St. Louis, MO, October 11th -15th.
Prof. Yongsheng Leng (MAE) attended the DoD Air Force Office of Scientific Research (AFOSR) “Surface and Interfacial Science Portfolio” Annual Program Review from October 13th – 15th. He reported the year's (2009) research accomplishments in his research project “Computational Nanotribology of Nanometer Confined Liquid Films.” The project focuses on the liquid structure and thermodynamics of ultrathin films. His postdoctoral research associate, Dr. Yajie Lei, and a new Ph.D. student, Mina Hong, also attended the workshop.
Professor Greg Shaw (EMSE) will deliver a keynote presentation on "Capability, Capacity, and Competence for Catastrophic Event Readiness" at the first International Conference on Policy and Research for Global Disaster Management in Seoul, Korea, on November 12th. The conference is organized by the Korean National Emergency Management Agency.
Other News
SEAS and Prof. Rhys Price Jones would appreciate any help from student, faculty, or staff volunteers in coordinating and running the local regional programming contest for ACM (The Association for Computing Machinery) that GW will host on Saturday, November 7th. All volunteers and team members will be entitled to one-year free memberships in ACM, as well as freely participating in the food and drink provided on the day of the contest. If you are interested in volunteering, please contact Prof. Price Jones at rhyspj@gwu.edu.
The SEAS Computing Facility hosted the DC chapter of the ACM (Association for Computing Machinery) as it held its fall professional development seminar series last Thursday and Saturday. The Washington Chapter of ACM started offering professional development seminars in 1968. Traditionally, these seminars have presented high-quality lectures and hands-on learning on topics of current interest to the local IT community for a relatively low cost.

Guest Vignette
Researchers in the Department of Computer Science are working on a project to defend against replica (clone) and Sybil attacks in mobile ad hoc networks. A node replica attack involves multiple physical (compromised) devices reporting the same identity, while in Sybil attacks the same physical device presents multiple distinct identities. These are insider attackers that could severely affect routing and other network functionalities. The challenges of this research lie in the dynamism caused by node mobility and the existence of collusions among compromised nodes. Traditional cryptographic techniques do not work as all clones and Sybil nodes are aware of the security information a legitimate node may possess. This research has been carried out by graduate research assistant Kai Xing together with his advisor Dr. Xiuzhen Cheng. Their approach is to investigate various invariants and identify paradoxes caused by mobility when clones and Sybil nodes exist in the network. Currently the research team is conducting extensive simulation study to verify the performance of their design. An implementation in a small test bed is also planned in the new future. Another graduate student, Amin Y. Teymorian, has jumped in recently and has started to contribute to the detection of Sybil attacks via logical location verification. He has obtained very promising results for location verification without resorting to any popular localization techniques.
