On April 8, Prof. Pinhas Ben-Tzvi (MAE) hosted a robotics workshop for 32 Loudon County high school students as part of GW's Science, Technology and Engineering Day at the Virginia Science and Technology Campus. The session focused on how the design of robotic systems is dependent on the integration of its mechanical, electrical, control, and computer subsystems. The students were given the chance to work on creating their own robots, and several teams later tested their robots, successfully following lines and avoiding obstacles within a maze. Prof. Ben-Tzvi was assisted in running the session by four of his doctoral students: William Rone, Zhou Ma, Omar Gilani, and Paul Moubarak. Media coverage of the session and the event included PBS News Hour Extra, the Loudon Times Mirror, and Leesburg Today. Photos taken at the event are also available here.

Luther Swift (MS candidate - ECE), a student working Prof. Matthew Kay's lab, was awarded an honorable mention for his research poster presentation at the GWUMC Health Sciences Research Day on March 23. His research topic was: Blebbistatin precipitation in Langendorff perfused heart preparations, Swift L, Asfour H, Sarvazyan N, Kay MW.
Huda Asfour (MS candidate - ECE) wrote a research article that has been accepted for publication in the IEEE Transactions on Biomedical Engineering: Asfour H, Swift LM, Sarvazyan NA, Doroslovacki M, Kay MW. "Signal decomposition of transmembrane voltage-sensitive dye fluorescence using a multiresolution wavelet analysis."
Together with his graduate students, Prof. Andrew Cutler is experimentally studying the mixing and combustion of gaseous fuels with air at supersonic speeds. These environments are difficult to probe with material probes so he is building and developing optical systems to make the measurements.
One technique - Coherent Anti-Stokes Raman Spectroscopy (CARS) - generates a signal laser beam from a small volume of the gas by crossing three pulsed laser beams of differing colors. The signal is then analyzed in a spectrometer to obtain its temperature and gas composition. These data are then used by theoretical modelers to develop codes for predicting these flows.
Prof. Cutler's work is sponsored by NASA and the USAF, which use these models in the design of supersonic combustion ramjets. Currently he does much of his work in labs at NASA Langley; however, in April he will take his instrument to the University of Virginia for tests at their "Aerospace Lab".

Christina Smyre (CS) successfully defended her doctoral dissertation, titled "Applying Standard Network Centrality Measures to Analyze Error Propagation and Measure the Security of a Software System," on April 7. This research uses network analysis measures of weighted directed graphs representing dependencies among software components. This research also introduces a novel technique for calculating flaw propagation scores that indicate a package's likelihood of propagating a flaw to another package. Software developers and testers can use the metrics identified in this study to quantitatively analyze the security of a software system. The research was conducted under the direction of Prof. C. Dianne Martin (CS).
Youngser Park (CS) successfully defended his doctoral dissertation, titled "Anomaly Detection in Time-Series of Graphs and Hypergraphs using Graph Features," on March 23. He presented a new graph statistic for detecting certain anomalies in times-series of graphs and hypergraphs and also introduced new fusion methods that combine multiple graph features adaptively. The results of his study will help to detect anomalous behavior of social interactions (e.g., "excessive chatters" in emails, Facebook, Twitter, etc.) at a certain time period without knowledge of the content of actual communications. The research was conducted under the direction of Prof. Abdou Youssef (CS).
Gloria Washington (CS) successfully defended her doctoral dissertation, titled "Understanding the Impact of User Frustration Intensities on Task Performance Using a Novel Adaptation of the OCC Theory of Emotions," on March 24. She presented a study that included the use of a novel adaptation of the OCC theory of emotions to separate emotions into varying degrees or amounts. She also incorporated the use of human-body based measures such as heart rate, posture, skin temperature, and respiration to determine frustration, along with task performances to measure the individual impact that each frustration intensity has on user productivity. The results of this study showed that individual intensities of frustration exist so that task performance is not degraded. Results from this study can be used by human factors engineers and usability testers to determine how much frustration is needed before task performance measures start to decrease. The research was conducted under the direction of Prof. Rhys Price Jones (CS).
Kerry McKay (CS) successfully defended her doctoral dissertation, titled "Analysis of ARX Round Functions in Secure Hash Functions," on March 25. She presented a new cryptanalytic technique that extends linear cryptanalysis to increase the adversary's advantage in Addition-Rotation-XOR (ARX) functions. She demonstrated the application of her ideas to entries in the SHA-3 competition organized by NIST for the next secure hash function standard. Her results on competition finalist Skein and semifinalist CubeHash were presented at the Second SHA-3 Conference. Her dissertation also explores links to truncated differential attacks and presents diffusion metrics. The results of her work will help cryptologists analyze and design ARX round functions in hash functions, block ciphers, and stream ciphers. This research was performed under the direction of Prof. Poorvi Vora (CS) and was sponsored by NSF grants DUE-0621334 and CCF-0830576.
Lewis Berman (CS) successfully defended his doctoral dissertation, titled "Similarity of Medical Measures in Social Health Networks," on March 25. The research was conducted under the direction of Prof. Shmuel Rotenstreich (CS).
Mira Yun (CS) successfully defended her doctoral dissertation, titled "Performance Enhancement in Heterogeneous Wireless Networks," on March 28. The research was conducted under the direction of Prof. Hyeong-Ah Choi (CS).
