چکیده

We introduce IceFS, a novel file system that separates physical structures of the file system. A new abstraction, the cube, is provided to enable the grouping of files and directories inside a physically isolated container. We show three major benefits of cubes within IceFS: localized reaction to faults, fast recovery, and concurrent filesystem updates. We demonstrate these benefits within a VMware-based virtualized environment and within the Hadoop distributed file system. Results show that our prototype can significantly improve availability and performance, sometimes by an order of magnitude.

Entanglement versus Disentanglement: Quantum Cryptography

In alternative disentanglement based quantum cryptosystem, classical channel cannot be used when the system is protected by no-cloning principle. But for the similar security criterion , it is discussed that classical channel can be used in alternative entanglement based quantum cryptosystem. A prototype of conventional entanglement based cryptosystem is recovered from alternative entanglement ...

Simulation of container operations in the marshaling yard – case study: Aprin station

In this project, an attempt has been made to investigate the loading/unloading operations for container loads on a at the Aprin station with a simulation approach. Simulation is an approximate imitation of the operation of a process or system whose performance is examined over time. In this study, Aprin station was selected as the largest railway station for container transport in Iran. To find...
