Methods for computation of spatial data cubes and analytical processing on such spatial data cubes are studied, with several strategies proposed, including approximation and partial materialization of the spatial objects resulted from spatial OLAP operations. Some techniques for selective materialization of ...
Our solution can adopt different data processing methods according to the type of aggregate functions, the efficiency of multiple versions data processing is improved. Furthermore, we proposes an algorithm of incremental computation of CUBE for max(min) function to reduce the access time of fact ...

Our technique exploits hardware-accelerated rendering (OpenGL) in order to perform the expensive visibility computation, which reduces the computation time of one planning step to a couple of minutes. Results are shown for two large indoor scenes-an artificial scene and a real world room-with ...
In order to combine each pair into a 32-bit data item, the cube is rounded to 22 bits, which introduces negligible error into the computation. This results in a lookup table of 96 * 4 = 384 bytes. An alternative approach uses the observation that all starting approximations have the...
Among computer simulation methods, one of them, the Reverse Monte Carlo (RMC) method17,18, produces three-dimensional structure of a molecular system that fits a given experimental data that originate from unknown molecular structure, such as, for example, diffraction and scattering data in the pr...

(e.g., hundreds, thousands, millions); whereas relative measurements are methods for deriving ratio scales from paired comparisons represented by absolute numbers [13].Relativemeasurements are useful in obtaining an overall ratio scale ranking of the alternatives. If the ratio produces repeatable and ...
