Fluid motion is classified as either laminar or turbulent. Flows that are smooth and ordered (laminar) may become complex and disordered (turbulent) as the flow speed increases, a process called transition to turbulence. Turbulent flow around cars, airplanes, and ships increases drag, which, in turn, forces vehicles to use more fuel and reduces the efficiency of wind-turbine blades. Assistant Professor Mihailo Jovanovic (Electrical and Computer Engineering) and his research group are developing theories and techniques for sensor-less flow control to prevent the transition to turbulence. An article about this work appears in the Spring 2011 MSI Research Bulletin. The image above shows how laminar flow around an aircraft wing or wind-turbine blade becomes complex and disordered as it moves away from the leading edge (e-fluids photo at bottom left by Miguel Visbal).
MSI researchers will present posters of their work at the 2011 MSI Research Exhibition on Monday, April 25, 1-3:30 p.m., on the fourth floor of Walter Library. The posters will be judged by a panel of MSI Principal Investigators and prizes will be awarded. Light refreshments will be served. We are very grateful to our sponsor, MathWorks, for their support of this event. More information can be found on the 2011 Research Exhibition webpage. The picture above, taken at the 2010 Research Exhibition, shows Ken Chen, a graduate student in the group of Professor Alexander Heger (Physics and Astronomy) talking about his award-winning poster with Professor Tom Jones (Astronomy, former MSI Interim Director). An article about Mr. Chen's research will appear in the Spring 2011 issue of the MSI Research Bulletin.
Galaxy is a framework developed at Penn State and adopted for use at the University of Minnesota as part of its core life sciences cyberinfrastructure. The Galaxy informatics tool provides the University's researchers with the necessary integrated environment to access data, run analytical workflows or pipelines, and share information. The initial focus of the installation is urgent needs in genomics research, and more specifically Next Generation Sequencing data analysis and data management. On February 16, 2011, the Galaxy informatics tool was opened for general access by University researchers. Dr. James Taylor from Emory University, a member of the original Galaxy team, gave two workshop presentations on Galaxy and its applications in genomics research. Dr. Anne-Francoise Lamblin, MSI's Research Informatics Support Systems Program Director (above), introduced the sessions. More information can be found at the Galaxy website.
The first stars of the early days of the universe hold the key to understanding the formation of the first heavy elements and first galaxies. These stars, which were very massive, died as Pair Instability Supernovae (PSNs). During the 2010 MSI Research Exhibition, graduate student Ke-Jung (Ken) Chen, a member of Professor Alexander Heger's research group in the School of Physics and Astronomy, presented a poster concerning research into the energetics, hydrodynamic instabilities, and nucleosynthesis of PSNs. The poster was selected as one of the finalists by the Exhibition judges and an article about this work will appear in the Spring 2011 MSI Research Bulletin. The image is from a simulation of a PSN model. The 2011 MSI Research Exhibition will be held on April 25.
MSI's newest supercomputer system, Koronis, will soon be ready for use by MSI researchers. Koronis is based on an SGI UV 1000 supercomputer and was funded by an NIH grant. MSI researchers who have grants from NIH are eligible to use the system. MSI's Acceptance Testing is ongoing. Complete information about Koronis and how to get access to the system will be posted on our website as it becomes available.
