Partial Matching of Planar Polylines Under Similarity Transformations
Given two planar polylines T and P with n and m edges, respectively, we present an Om2 n2  time, Omn space algorithm to nd portions of the text" T which are similar in sh...

Towards Desynchronization of Multi-hop Topologies
In this paper we study desynchronization, a closelyrelated primitive to graph coloring. A valid graph coloring is an assignment of colors to nodes such that no node’s color is t...

Sizing the horizon: the effects of chart size and layering on the graphical perception of time series visualizations
We investigate techniques for visualizing time series data and evaluate their effect in value comparison tasks. We compare line charts with horizon graphs--a space-efficient time ...
