Table 4: Spatio-temporal queries posed on Precipitation

in An Evaluation of Multi-resolution Storage for Sensor Networks
by Deepak Ganesan, Ben Greenstein, Denis Perelyubskiy, Deborah Estrin, John Heidemann 2003
"... In PAGE 8: ... Drill-down Queries. Our implementation considers four types of queries (shown in Table4 ) that involve different extents of spatio- temporal processing that evaluate both advantages and limitations of wavelet compression. The GlobalYearlyEdge and LocalYear- lyMean queries explore features for which wavelet processing is typically well suited.... In PAGE 9: ... Our goal in this section is to demonstrate the search features of the system and prove our claim that multi-resolution storage can be useful for a broad variety of queries. To evaluate performance, each of the queries shown in Table4 was posed over the dataset. For yearly queries (GlobalYearlyEdge and and GlobalYearlyMax), there were 45 instances each, since there are 45 years of data.... In PAGE 10: ... Figure 6.2 shows the variation of query quality for queries defined in Table4 for different levels of drill-down. Performance for LocalYearlyMean, GlobalYearlyMax and Local- DailyMax queries are very similar, as shown in Figure 6.... In PAGE 10: ... Evaluating Training using Limited Information In our evaluation, we use a training period of two epochs of data (10% of total deployment time) to predict the query accuracy for the entire dataset. Summaries are constructed over the training set, and all queries in Table4 are posed over these summaries. Ideally, the error obtained from the training set would mirror error seen by the omniscient scheme.... In PAGE 11: ... The first column in Table 7 shows the difference between the per- formance of training and the optimal schemes. These results are ag- gregate results over a range of storage sizes (0 - 100KB) and query types (shown in Table4 ). Training performs exceedingly well, and in fact is on average less than 1% worse than the optimal solution.... ..."

"... In PAGE 18: ...equences. Figure 17 shows six examples of the motion energy images generated by different people. The similarity scores of these to the corresponding expression templates are shown below each figure. Table4 shows the results of this recognition test for five different expressions by different subjects. The scores show that all the five expressions were correctly identified.... ..."

The most striking feature to be observed in Table2 is its similarity to the domain, particle, and particle interaction table for rule A. Indeed the number of domains, the number of particles, and the number and types of particle interactions are identical in the two tables.... ..."
