A computer-implemented method of predicting energy use for a route including inputting map data of roads included in K trips in a geographical area, predictors of rate of energy use along the roads, and energy consumption data of the K trips. The method includes dividing each of the roads in the map data for all the trips into segments of length measure λ; grouping the segments from the trips into a number N of clusters, using an algorithm to build a model predicting the weights Wbased on solving a system of equations, one per trip, assigning the predicted weight applied to the cluster in which the segment was grouped and storing a segment ID with the corresponding cluster ID or predicted rate of energy use Yto allow prediction of energy use for a route in the geographical area incorporating one or more of the segments.

A fresenel zoned microstructured optical fiber is described. The fiber is constructed of concentric zones, each zone being defined by discontinuities in the refractive index. The refractive index within each zone may either be constant or may vary, for example each zone being a section of a parabola or hyperbola. The fiber may be used as a lens, for example for coupling light between fibers with different core sizes.
