A Solution to View Management to Build a Data Warehouse
Several techniques exist to select and materialize a proper set of data in a suitable structure that manage the queries submitted to the online analytical processing systems. These techniques are called view management techniques, which consist of three research areas: 1) view selection to materialize, 2) query processing and rewriting using the materialized views, and 3) maintaining materializ...
متن کاملFriction Angle Measurements on a Naturally Formed Gravel Streambed: Implications for Critical Boundary Shear Stress
We report the first measurements of friction angles for a naturally formed gravel streambed. For a given test grain size placed on a bed surface, friction angles varied from 10" to over 100'; friction angle distributions can be expressed as a function of test grain size, median bed grain size, and bed sorting parameter. Friction angles decrease with increasing grain size relative to the median ...
متن کاملOn-line digit set conversion in real base
Let be a real number > 1. The digit set conversion between real numbers represented in xed base is shown to be computable by an on-line algorithm, and thus is a continuous function. When is a Pisot number the digit set conversion is computable by an on-line nite automaton.
متن کاملStratified Median Ranked Set Sampling: Optimum and Proportional Allocations
In this paper, for the Stratified Median Ranked Set Sampling (SMRSS), proposed by Ibrahim et al. (2010), we examine the proportional and optimum sample allocations that are two well-known methods for sample allocation in stratified sampling. We show that the variances of the mean estimators of a symmetric population in SMRSS using optimum and proportional allocations to strata are smaller than ...
متن کاملAbrasion-set limits on Himalayan gravel flux.
Rivers sourced in the Himalayan mountain range carry some of the largest sediment loads on the planet, yet coarse gravel in these rivers vanishes within approximately 10-40 kilometres on entering the Ganga Plain (the part of the North Indian River Plain containing the Ganges River). Understanding the fate of gravel is important for forecasting the response of rivers to large influxes of sedimen...
