We analyze an electoral competition model with two offi ce motivated candidates where a) one of the two candidates enjoys a non-policy advantage and b) voters use shortcuts (e.g. interest-group/media endorsements) to infer the policy platforms of the competing candidates. That is, voters have imperfect information about the candidates’policy proposals: they do not observe the exact policy propo...

Systems consisting of magnetic particles embedded in a silica matrix have been used in magnetic recording, their study being thus an actual theme of research. In this work, we report some of the main results of a systematic study conducted to determine properties of the magnetic phases of the system Co2SiO4. The study also deals with the magnetic parameters of the composites Co2O3±SiO2, in an a...

Most numerical applications using arrays require extensive program transformation in order to perform well on current machine architectures with deep memory hierarchies. These transformations ensure that an execution of the application exploits data-locality a n d uses the caches more eeectively. The problem of exploiting data-locality i s w ell understood only for a small class of applications...
