Faculty News

Research:

Prof. Guru Venkataramani (ECE) and Prof. Gabriel Parmer (CS) were jointly awarded a one-year NSF grant of nearly $140,000 for their research project, titled "Software and Hardware Integration with Feedback and Transparency for Many-Core Computing." The research explores hardware-software cooperative mechanisms to address the challenges of manycore computing. Their graduate students, Jie Chen and Qi Wang, will also participate in this project.

Books & Papers:

Prof. Michael Keidar (MAE) has had the following paper published: A. Shashurin, J. Li, T. Zhuang, M. Keidar and I.I. Beilis, "Application of electrostatic Langmuir probe to atmospheric arc plasmas producing nanostructures," Physics of Plasmas, 18, 073505 (2011).

Prof. Vesna Zderic (ECE) and her doctoral student, Shutao Wang, recently published the following article: Wang S, Frenkel V, Zderic V., "Optimization of Pulsed Focused Ultrasound Exposures for Hyperthermia Applications," in the Journal of the Acoustical Society of America, 2011; 130:599-609.

Conferences & Presentations:

Several SEAS faculty, along with their post-doctoral scholars and students, presented papers at the 11th U.S. National Congress on Computational Mechanics, July 25-29, in Minneapolis, MN:

Profs. James Lee and Ken Chong (both of MAE) organized a mini-symposium, "Mechanics of Materials from Nano to Macro Scale," at the Congress, and Prof. Lee co-authored the following presentations with his colleagues and his students: 1) James Chen, James Lee, and Chunlei Liang, " Micropolar Electromagnetic Fluids;" 2) Jiaoyan Li, James Lee, and Ken Chong, "Mechanics of Composite Material Reinforced by Stochastically-dispersed Particles;"and 3) James Lee, Xianqiao Wang, James Chen, and Jiaoyan Li, "Non-equilibrium Molecular Dynamics Simulation of Thermal-Mechanical-Electromagnetic Coupling Phenomena."

At the AIAA/ASME/SAE/ASEE Joint Propulsion Conference, he and/or his students also presented papers: 1) P. Vail, A. Pancotti, T. Zhuang, A. Shashurin, M. Keidar, "Performance Characterization of micro-cathode arc thruster." 2) T. Zhuang, A. Shashurin, G. Teel, D. Chiu, M. Keidar, "Co-axial Micro-Cathode Arc thruster (CA-mCAT) Performance Characterization." 3) Lubos Brieda, Shaunak Pai, Yitzy Dachman, and Michael Keidar, "Wall Interaction in Hall thrusters with Magnetic Lens Configuration."

Prof. James Lee (MAE) attended the 13th International Conference on Mesomechanics, July 6-8 in Vicenza, Italy, where he co-authored the following presentations: 1) James D. Lee, Xianqiao Wang, James Chen, and Jiaoyan Li, "Interatomic Potential: the Constitutive Equations at Nanoscale"; 2) Keke Tang, Zhaoxia Li, Xianqiao Wang, and James Lee, "Numerical simulation of the defected beam based on a multiple-time-scale algorithm."

Other News

The Cyber Security Policy and Research Institute (CSPRI) has received a nine-month, $75,000 extension to their existing sub-agreement with Prince George's Community College to provide management support services to CyberWatch, a network of more than 60 two- and four-year institutions whose aim is to increase the quantity and quality of the cybersecurity workforce of the nation. The project co-PIs are Profs. Shelly Heller and Costis Toregas (both of CS), and the tasks in this extension include support of a Collegiate Cyber Defense Competition and the exploration of a possible National Cyber League that would provide continuous opportunities for cyber learning using a weekly "football league" model. Another task is to provide general management services for the entire network, as well as liaison services to private industry interested in forging partnerships with academic institutions in cyber security. For more information, contact Prof. Toregas at toregas1@gwu.edu.
