Dual Anti-de Sitter Superalgebras from Partial Supersymmetry Breaking
The partial breaking of supersymmetry in anti\char21{}de Sitter space can be accomplished using two of four dual representations for the massive $\mathrm{OSp}(1,4)$ spin-3/2 multiplet. The procedure gives rise to a set of dual $N=2$ supergravities and supersymmetry algebras.
DUAL SUPERSYMMETRY ALGEBRAS FROM PARTIAL SUPERSYMMETRY BREAKING
Abstract The partial breaking of supersymmetry in flat space can be accomplished using any one of three dual representations for the massive N=1 spin-3/2 multiplet. Each of the representations can be “unHiggsed”, which gives rise to a set of dual N=2 supergravities and supersymmetry algebras.
Substation automation based on IEC 61850 with new process-close technologies
New technologies in primary equipment like nonconventional instrument transformers require new interfaces to the substation automation system. The future standard IEC 61850 perfectly supports this requirement. With the introduction of the new technologies and the use of IEC 61850, a more decentralized architecture of the substation automation system will be possible. This provides several benefits but a careful system design is required to maintain the overall reliability of the system.
