Prandtl-Meyer Reflection for Supersonic Flow past a Solid Ramp
Myoungjean Bae, Gui-Qiang Chen, Mikhail Feldman
We present our recent results on the Prandtl-Meyer reflection for supersonic potential flow past a solid ramp. When a steady supersonic flow passes a solid ramp, there are two poss…
High-Performance Concurrency Control Mechanisms for Main-Memory Databases
Per-Åke Larson, Spyros Blanas, Cristian Diaconu +3
A database system optimized for in-memory storage can support much higher transaction rates than current systems. However, standard concurrency control methods used today do not sc…
Towards Cost-Effective Storage Provisioning for DBMSs
Ning Zhang, Junichi Tatemura, Jignesh M. Patel +1
Data center operators face a bewildering set of choices when considering how to provision resources on machines with complex I/O subsystems. Modern I/O subsystems often have a rich…
PDS 144: The First Confirmed Herbig Ae - Herbig Ae Wide Binary
J. B. Hornbeck, C. A. Grady, M. D. Perrin +13
PDS 144 is a pair of Herbig Ae stars that are separated by 5.35" on the sky. It has previously been shown to have an A2Ve Herbig Ae star viewed at 83\circ inclination as its northe…
Jet energy measurement with the ATLAS detector in proton-proton collisions at sqrt(s) = 7 TeV
ATLAS Collaboration
The jet energy scale (JES) and its systematic uncertainty are determined for jets measured with the ATLAS detector at the LHC in proton-proton collision data at a centre-of-mass en…
Central Regions of Barred Galaxies: Two-Dimensional Non-self-gravitating Hydrodynamic Simulations
Woong-Tae Kim, Woo-Young Seo, James M. Stone +2
The inner regions of barred galaxies contain substructures such as off-axis shocks, nuclear rings, and nuclear spirals. These substructure may affect star formation, and control th…
