This paper proposes microarchitecture-driven dynamic voltage scaling as a viable solution to power efficient architectures, with little or no performance penalty. The run-time behavior exhibited by common applications, with active periods, alternated with stall periods due to cache misses, is exploited to reduce the dynamic component of power consumption via selective voltage scaling. As it is ...

The effect of the tip gap size on the performance of a multistage axial compressor was studied by means of computational fluid dynamics (CFD). It was found that the performance of the compressor was very sensitive to the size of the tip gap. By increasing the gap size, the stall margin value, the total pressure ratio and the compressor efficiency reduced considerably. The flow field at the tip ...

TALL-1/BAFF/BLyS was recently identified as a member of the tumor necrosis factor (TNF) ligand family. The crystal structure of the functional soluble TALL-1 (sTALL-1) has been determined at 3.0 A. sTALL-1 forms a virus-like assembly with 200 A diameter in the crystals, containing 60 sTALL-1 monomers. The cluster formation is mediated by a "flap" region of the sTALL-1 monomer. The virus-like as...

The unsteady flow characteristics and responses of an NACA 0012 airfoil fitted with a bio-inspired morphing trailing edge flap (TEF) at near-stall angles attack (AoA) undergoing downward deflections are investigated Reynolds number 0.62 × 106 near stall. An geometric parametrization dynamic meshing scheme used to drive the motion. objective is determine susceptibility actuation viability rapid ...
