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...

Numerical studies on a paradox for non-cooperative static load balancing in distributed computer systems
Numerical examples of a Braess-like paradox in which adding capacity to a distributed computer system may degrade the performance of all users in the system have been reported. Un...

Downlink MIMO Systems Using Cooperation Among Base Stations in a Slow Fading Channel
To increase the achievable sum rate of downlink MIMO (Multiple Input Multiple Output) systems, the cooperation among Base Stations (BS) is investigated in a slow fading channel. Th...
