A graph in van Eck and Waltman [JASIST 60(8), 2009, p. 1644], representing the relation between the Association Strength and the Cosine, is partially explained as a sheaf of parabolas, each parabola being the functional relation between these similarity measures on the trajectories . X Y a  , a constant. Based on earlier obtained relations between Cosine and other similarity measures (such as ...

Compute clusters are consuming more power at higher densities than ever before. This results in increased thermal dissipation, the need for powerful cooling systems, and ultimately a reduction in system reliability as temperatures increase. Over the past several years, the research community has reacted to this problem by producing software tools such as HotSpot and Mercury to estimate system t...
