Erasure coding is a technique for achieving high availability and reliability in storage and communication systems. In this paper, we revisit the analysis of erasure code replication and point out some situations when whole-file replication is preferred. The switchover point (from preferring whole-file replication to erasure code replication) is studied,… (More)
Two types of ammonium uranyl nitrate , were thermally decomposed and reduced in a TG-DTA unit in nitrogen , air, and hydrogen atmospheres. Various intermediate phases produced by the thermal decomposition and reduction process were investigated by an X-ray diffraction analysis and a TG/DTA analysis.
Variable-bit-rate (VBR) encoding is known to provide a more consistent visual quality compared to constant-bit-rate (CBR) encoding. However, the resultant bit-rate variations greatly complicated the allocation of disk and network bandwidth in a video-on-demand system. This paper investigates a new scheduling algorithm with monotonic-decreasing rate… (More)
Jugular foramen neurilemmoma is frequently manifested as a jugular foramen syndrome or extraaxial mass. Neurilemmoma arising from the cranial nerves of the foramen, although rare, may be manifestated as an intracranial or extracranial mass lesion. When the tumor is located only in the intracranium, it is often misdiagnosed as an acoustic neurinoma or a… (More)
