Derivation of Passage-time Densities in PEPA Models using ipc: the Imperial PEPA Compiler
We present a technique for defining and extracting passage-time densities from high-level stochastic process algebra models. Our high-level formalism is PEPA, a popular Markovian...

Generalized Processor Sharing with Long-Range Dependent Traffic Input
In this paper, we develop an upper bound on the individual session queue length of long range dependent (LRD) traffic under the generalized processor sharing (GPS) scheduling disc...

PROFS-Performance-Oriented Data Reorganization for Log-Structured File System on Multi-Zone Disks
I/O is a major performance bottleneck in modern computer systems. Modern disks use the Zone-Bit-Recording (ZBR) technology to increase the capacity. A direct consequence of ZBR is...
