Conferences & Presentations:
On July 1, Prof. Philippe Bardet (MAE) presented the talk “Systematic timing errors in laser based transit time velocimetry” at the PIV 2013 conference, held July 1-3 at Delft University (The Netherlands).  A paper by the same title, co-authored with Matthieu Andre (MAE doctoral candidate) and Douglas Neal (LaVision, Inc), will be published in the conference proceedings.  On July 5, Prof. Bardet visited INSEAN (the Italian Ship Model Basin) in Rome, Italy, where he presented the talk “Air entrainment and gas transfer in capillary waves.”

Prof. Erica Gralla (EMSE) gave a talk at the 2013 Behavioral Operations Management Conference, held June 27-29 in Ann Arbor, MI. The talk, titled “Understanding and quantifying experts' goals in humanitarian aid delivery,” is joint work with Jarrod Goentzel and Charles Fine at MIT.

Prof. Michael Plesniak (MAE) attended the 43rd AIAA Fluid Dynamics Conference and Exhibit, held June 24-27, in San Diego, CA.  He chaired two sessions: APA-15/FD-14: Bio-Inspired Aerodynamics I, and APA-33/FD-33: Bio-Inspired Aerodynamics II.  Prof. Plesniak participated in the meeting of the Fluid Dynamics Technical Committee, where he chairs the Annual Highlights Article subcommittee, is a member of the Experimental & Theoretical Fluid Dynamics subcommittee, and serves as the liaison to the Public Policy Committee.

Prof. Kausik Sarkar (MAE) gave the invited talk “Effects of viscoelasticity on drop dynamics and emulsion rheology” at the 10th Frontiers in Applied and Computational Mathematics (FCAM) Conference, held in Newark, NJ on May 31.

On July 10, Prof. Timothy Wood (CS) published a paper titled “HybridMR: A Hierarchical MapReduce Scheduler for Hybrid Data Centers” at the IEEE International Conference on Distributed Computing Systems, held in Philadelphia, PA.  The paper was written in collaboration with Bikash Sharma and Chita Das from Penn State University.  The conference had a 13% paper acceptance rate.

Other News:

The GW Institute for Nanotechnology is pleased to announce the winner of the 2013-2014 Interdisciplinary Research Grant, Prof. Volker Sorger (ECE).  Prof. Sorger's proposed research will investigate the first optical transistor based on graphene.  Toward this goal, his team will collaborate with Prof. Michael Keidar (MAE), who is an expert in graphene research.  The value of the grant is approximately $10,000.

Prof. Pinhas Ben-Tzvi (MAE) has been notified by InTech Publisher that his book chapter, “A Mechatronic Perspective on Robotic Arms and End-Effectors,” in the book Intelligent Mechatronics has been downloaded over 5,000 times, as of June 24, 2013. According to the publisher, the top downloads of the book chapter were from the United States, India, China, Germany, and Japan.  Intelligent Mechatronics is published by InTech Open Access Publisher, Feb 2011, pp. 3–20 (ISBN-13: 978-953-307-300-2).  Prof. Ben-Tzvi's book chapter was co-authored with his former doctoral student, Paul Moubarak.

The paper “Cold atmospheric plasma in cancer therapy,” co-authored by Prof. Michael Keidar (MAE), Alex Shashurin (MAE), Olga Volotskova (MAE), Mary Ann Stepp, Priya Srinivasan, Anthony Sandler, and Barry Trink, is currently at the top of the most read papers in Physics of Plasmas.

Student News

The work of Matthieu Andre (MAE doctoral candidate) and Prof. Philippe Bardet (MAE) was cited in the new LaVision, Inc. brochure on time-resolved particle image velocimetry.  LaVision is the leading supplier of instruments for fluid mechanics measurements.

On June 24, MAE doctoral student Andrew DeJong presented his paper, “Massively parallel 3D spectral difference solver for simulating vortex-induced vibrations of circular cylinders,” at the 43rd AIAA Fluid Dynamics Conference and Exhibit, held in San Diego, CA.

At the invitation of NASA astronaut Charles Camarda (SEAS, MS '80), MAE doctoral candidate Christopher Blower attended the Innovative Conceptual Engineering Design (ICED) 2013 Innovation Boot Camp, which was hosted at Penn State University during the week of June 17.  The workshop is held annually and has a two-fold purpose: 1) to focus on one "epic"  engineering challenge that NASA wants to solve (the topic changes each year); and 2) to encourage STEM education in the U.S.  Participants spend the week learning about the challenge from an array of subject matter experts and then working in teams to generate ideas to address the challenge, as well as ways to teach the topic to high school STEM students.  The participants included 22 university students and 30 high school STEM teachers.  Christopher attended as a participant and as an expert matter presenter; he was one of only two presenters chosen from the university student participants. This year's challenge was to look at the application of current technology to asteroid mining.

Mahsa Ghafarianzadeh (CS doctoral student) presented the paper “Climate Prediction via Matrix Completion” as a poster and a short oral “lightning presentation” in the Late-Breaking Papers Track at the Twenty-Seventh Conference on Artificial Intelligence (AAAI), held July 14-18, in Bellevue, WA.  The paper is co-authored by Mahsa and Prof. Claire Monteleoni (CS).  AAAI is one of the top two international conferences on artificial intelligence.  Mahsa is advised by Prof. Gabe Sibley.

The paper “Convergence analysis of stochastic gradient descent on strongly convex objective functions,” co-authored by Cheng Tang (CS doctoral candidate) and Prof. Claire Monteleoni (CS), appeared at the International Workshop on Advances in Regularization, Optimization, Kernel Methods and Support Vector Machines (ROKS), 2013, held July 8-10, in Leuven, Belgium.
