Using Optimistic Atomic Broadcast in Transaction Processing Systems

André Schiper, Fernando Pedone

Atomic broadcast primitives are often proposed as a mechanism to allow fault-tolerant cooperation between sites in a distributed system. Unfortunately, the delay incurred before a message can be delivered makes it difficult to implement high performance, s ...

Poloidal polarimeter system for current density measurements in ITER

The polarimeter system for ITER features 10 viewing chords covering almost the full poloidal cross section of the plasma in a fan-like arrangement. The 10 laser beams all enter the plasma via 150 mm diam penetrations through the diagnostic plug at the low- ...

Design study of a large-gap superconducting spectrometer dipole

The conceptual design of the large gap Spectrometer Dipole for the LHC-b experiment is presented here. The required acceptance implies a gap height of 3.6 m and a width of 4.3 m. Although the magnetic induction of the 1.92 m long magnet is only 1.1 T, it t ...

Decision aid function for restoration of transmission power systems: conceptual design and real time considerations

Tatjana Kostic

This paper deals with the conceptual design of a decision aid function for restoration (DAFFOR) of transmission networks after major black-outs, and in particular with real time considerations. Some important characteristics of the proposed DAFFOR are: (a) ...
