Awards & Recognition:

Dr. James Chen (MAE lecturer) has been elected an Honorary Fellow of the Australian Institute of High Energetic Materials.

For his continuous support of the American Society of Civil Engineers-National Capital Section (ASCE-NCS) and the student ASCE chapter at SEAS, Prof. Majid Manzari (CEE) will receive the Meritorious Service Award from the ASCE-NCS at their April 19 banquet.


Prof. Chunlei Liang (MAE) was invited by the High Altitude Observatory of the National Center for Atmospheric Research (NCAR) to work in Boulder, CO, for a month this summer.  He will conduct research to model the sun on NCAR's massively parallel computers.


Prof. Pedro Silva (MAE) published the paper "Seismic Performance of a Concrete Bridge Bent Consisting of Three Steel Shell Columns" in Earthquake Spectra Online (EQS), the professional journal of the Earthquake Engineering Research Institute.

Conferences & Presentations:

Prof. Tianshu Li (CEE) attended the American Physical Society's March Meeting 2011 in Dallas, TX, March 21 - 25. At the meeting, he presented his recent theoretical modeling work, titled "Embedded Si Nanocrystals: Tailoring Interfaces to Manipulate Electronic States," in the session Optical Properties of Semiconductor and Metal Nanostructures.

Prof. Julie Ryan (EMSE) co-authored a paper presented by Eneken Tikk (lead author) at the Georgetown Cyber Project Conference on March 29. The paper results from a multi-year collaborative effort among its four concept authors to explore the legal issues associated with cybersecurity and cyberwarfare: Eneken Tikk (2011) "10 Rules of Behavior for Cyber Security: Concept by Prof. Dan Ryan (National Defense University), Prof. Julie Ryan (George Washington University), Maeve Dion (Stockholm University), Eneken Tikk (NATO Cooperative Cyber Defence Centre of Excellence)."

Guest Vignette

Today a file system with billions of files, millions of directories, and petabytes of storage is no longer a rarity. As file systems grow, users are increasingly eager to perform complex queries, such as "How many files have been updated in the past ten days?", and "Which are the five largest files that belong to John?". The first is an example of an aggregate query, which provides a high-level summary of all or part of the file system; the second is a top-k query, which locates the k files and/or directories that have the highest score according to a scoring function. Applications that require just-in-time analytics over large file systems, such as data management, archiving, enterprise surveillance, etc., often require fast processing of these queries.

To address this need, Profs. Howie Huang (ECE) and Nan Zhang (CS) have designed and developed "Glance," a just-in-time query processing system that can produce accurate query answers within a short amount of time. Glance achieves this through quick analysis based on a small number of samples (files or folders), which can be collected from a very large file system. It works seamlessly with the tree structure of the system and can be applied instantly over any new file system. This research was published in February at the USENIX conference on File and Storage Technologies (FAST 2011).

Glance opens the door to a new paradigm for just-in-time storage forensics that could potentially help prevent future WikiLeaks-like occurrences. For example, border patrol agents may need to count the number of encrypted files in a traveler's hard drive in order to determine whether he could be transporting sensitive documents. The agent must make a determination quickly, as he can only detain each traveler for an extremely limited amount of time. Once fully developed, Glance will be able to help facilitate these types of storage forensics tasks.  (Provided courtesy of Prof. Howie Huang of the Department of Electrical and Computer Engineering)

Dissertation Defenses

Razaq Ferhadi (CEE) successfully defended his doctoral dissertation, titled "Evaluation of Options to Extend Span Range of Precast Prestressed Concrete Bridge Girders During Preliminary Design," on March 11.  He presented a parametric study and investigated the impact of using the available options and trends (individually and simultaneously) on extending the span range of bridge girders and the corresponding cost of the superstructure. The results of his study will help design engineers decide which options to consider based on the project criteria. The research was conducted under the direction of Prof. Sameh Badie (CEE).
