Eclipsing binaries in open clusters . I . V 615 Per and V 618 Per in hPersei ⋆
We derive absolute dimensions for two early-type main sequence detached eclipsing binaries in the young open cluster hPersei (NGC 869). V615Persei has a spectral type of B7V and a period of 13.7 days. V618Persei is A2V and has a period of 6.4 days. New ephemerides are calculated for both systems. The masses of the component stars have been derived using high-resolution spectroscopy and are 4.08...
متن کاملDisk I/O Performance-per-Watt Analysis for Cloud Computing
Assessing disk I/O performance and power consumption associated with a given cloud workload is important especially for workloads that are bounded by disk I/O. Disk performance becomes a bottleneck for achieving higher performance and lower power consumption especially when memory size is not enough to process large blocks of data. This will lead to a negative impact on the Quality-of-Service (...
