cobalt oxide (co3o4) nanorods were prepared by a simple co-precipitation method using ethanol solution of cobalt nitrate as precursor and cetyl trimethylammonium bromide (ctab) as surfactant. morphological properties of the nanoparticles were characterized. xrd measurement exhibited the structure of co3o4 nanocrystals for annealed samples. the sem images revealed that the particles changed from...

Co-scheduling processes on different cores in the same server might lead to excessive slowdowns if they use a shared resource, like the memory bus. If possible, processes with a high shared resource use should be allocated to different server nodes to avoid contention, thus avoiding slowdown. This paper introduces the simple scheme of avoiding to coschedule twins, i.e., several instances of the...

In two experiments, we explored the effects of co-occurrence and semantic relationships in the associative priming of faces. In Experiment 1, pairs of computer-generated human faces were presented simultaneously (i.e., they co-occurred) with no associated semantic information attached to them. A significant facilitation effect in the subsequent recognition of these paired faces (priming) was ob...

The power line (PL) is a shared medium, so that PL devices deployed on the same PL network must share the available capacity. Since there are today several incompatible technologies in the market and no available standard, it is expected that these different technologies will continue to be deployed for some time thus giving rise to the necessity of adopting coexistence mechanisms, i.e. mechani...

When creating Semantic Web data, users have to make a critical choice for a vocabulary: only through shared vocabularies can meaning be established. A centralised policy prevents terminology divergence but would restrict users needlessly. As seen in collaborative tagging environments, suggestion mechanisms help terminology convergerce without forcing users. We introduce two domain-independent a...
