Indexing Temporal Data with Virtual Structure
... The structure of our indexing method is based on the observation, that all data and query intervals of interest represented in two dimensional space lie in the isosceles, right-angle triangle with vertices at (0,0), (0, λ ) and (λ , λ ), which lies above the line E = S. We call this triangle the bas ...
