  • Publication number: 20120109391
    Abstract: In a method for managing energy demand in an infrastructure, a coefficient of performance (COP) of the infrastructure as a function of time is determined. The COP is a measure of efficiency of the infrastructure. In addition, an energy demand on the infrastructure as a function of time is determined and an energy demand schedule for the infrastructure that temporally reallocates the energy demand based upon the determined COP of the infrastructure is determined.

  • Publication number: 20120089941
    Abstract: Visual structures are produced to represent corresponding motifs, where the motifs correspond to repeating patterns in an input data set, where sizes of the visual structures are based on values of a characteristic associated with the motifs, and where a first of the motifs is nested within a second of the motifs to represent a hierarchical relationship of the patterns represented by the first and second motifs. The visual structures of corresponding motifs are presented for display in a visualization screen, where the visualization screen depicts the data in the input data set with the visual structures overlapping parts of depicted data. Interactive input is received specifying modification of a region containing motifs, wherein the specified modification includes interactive distortion of the visual structures in the region to change a size of the visual structures in the region.
