Prof. Kausik Sarkar (MAE) has been elected a Fellow of The American Physical Society for “Fundamental contributions and creative analysis of flows with droplets—effects of viscoelasticity, emulsion rheology, normal stress differences, wall-induced migration, and modeling of encapsulated contrast microbubbles for ultrasound imaging.” He was awarded the fellowship certificate during the plenary session of the 67th annual meeting of the American Physical Society (APS) Division of Fluid Dynamics, held November 23-25 in San Francisco CA. The criterion for election as a fellow of APS is “exceptional contributions to the physics enterprise; e.g., outstanding physics research, important applications of physics, leadership in or service to physics, or significant contributions to physics education. Fellowship is a distinct honor signifying recognition by one's professional peers.” Each year, no more than one-half of one percent of the then-current membership of the Society is recognized by their peers for election to the status of Fellow in The American Physical Society.

Her tutorial is titled “ Climate Change: Challenges for Machine Learning,” and her co-presenter is Arindam Banerjee, University of Minnesota, Twin Cities. The conference attendance is in the range of 1000-2000, so the tutorial attendance is typically in the hundreds.

Prof. Michael Plesniak (MAE) attended the 67th annual meeting of the American Physical Society (APS) Division of Fluid Dynamics, held November 23-25 in San Francisco CA. He chaired the D5 Biofluids: Red Blood Cells session and co-authored five presentations with his students and collaborators: Prof. Adrienne Hancock (Dept. of Speech and Hearing Sciences), Prof. Chunlei Liang (MAE), Research Prof. Kartik Bulusu (MAE), post-doctoral scholar Adam Apostoli, doctoral students Ian Carr and Christopher Cox, master’s student Elizabeth Hubler, undergraduate student Lucas Pollok, summer intern Daniel Plesniak (Haverford College), and colleagues from Stanford University. The presentations were as follows: 1) “Wavelet analysis of hemispheroid flow separation toward understanding human vocal fold pathologies,” 2) “Self-oscillating Vocal Fold Model Mechanics: Healthy, Diseased, and Aging,” 3) “Towards A Fast High-Order Method for Unsteady Incompressible Navier-Stokes Equations using FR/CPR,” 4) “Velocimetry modalities for secondary flows in a curved artery test section,” and 5) “3D separation over a wall-mounted hemisphere in steady and pulsatile flow.” As chair of the Fluid Dynamics Prize Committee, Prof. Plesniak also attended the Division of Fluid Dynamics Executive Committee, which held its annual business meeting during the conference.

On November 23, Prof. Kausik Sarkar (MAE) presented a talk at the 67th annual meeting of the American Physical Society (APS) Division of Fluid Dynamics. The title of the talk was “Lateral migration and diffusion of a mechanical engineer through emulsion of drops induced by Andy's influence.”

Prof. Rumana Riffat (CEE) took her undergraduate students on a field trip to the Alexandria wastewater treatment and resource recovery plant, Alexandria Renew Enterprises. Prof. Lisa Benton-Short, academic program director of sustainability, also participated in the trip. The students received a tour of the plant and learned about the various advanced treatment processes that were used. The production of Class A biosolids fertilizer, biogas and electricity from sludge was an important learning aspect of the tour.

Prof. Volker Sorger (ECE) recently was featured in a video by the International Photonics and Optics Society (SPIE) titled “Plasmonic chips enable new switching efficiency.” In the video, Prof. Sorger shows how new developments in integrated nanophotonics and plasmonics may address the dramatic growth in the amount of energy needed for data processing.

Guest Vignette

Embedded systems dominate the computational domain. They account for 97% of all processors in the world, and are taking an increasingly conspicuous role in the management of our lives. Computation is truly embedded everywhere, and as the Internet of Things increases in prominence, this trend will only accelerate. Unfortunately, the software infrastructures that have traditionally accommodated such systems are inadequate to address the non-functional requirements of current and future systems. These requirements include enhanced reliability, security, and the effective use of the massive parallelism provided by current processors.

The Composite component-based operating system is research conducted by Prof. Parmer and numerous Ph.D. and undergraduate students at GW that fundamentally redefines the software structure of future embedded systems to address the shortcomings of existing systems. Recently, Ph.D. student Qi Wang and Prof. Parmer published work on a system called FJOS that effectively harnesses massively multi-core processors in real-time systems for more feature-rich control of the physical world.

FJOS provides an OpenMP runtime that coordinates parallelism with five times less overhead than existing systems at 40 cores, despite decades of optimization on those systems. This work recently received the best student paper award at the IEEE Real-Time and Embedded Technology and Applications Symposium (RTAS), the top conference in systems aspects of real-time. Current work takes this further and provides the first system that, for fundamental operating system functionalities, can use each of a massive numbers of cores as effectively as a single core—a significant challenge that is the final goal of all parallel systems. This work empowers software to make the necessary leap in intelligence required for the next generation of embedded systems ranging from the invisible computation that is pervasive in our infrastructure, all the way to robotic cars. Composite is funded by NSF (including the Career Award) and the Office of Naval Research. (Provided courtesy of Prof. Gabe Parmer, Department of Computer Science)
