The map cube operator for spatial multidimensional databases supports spatial aggregation using geometric union and enables information visualization in maps. In this paper, we propose three extension to the map cube operator. First, support for spatial aggregate functions other than geometric union. Second, support for several spatial aggregate functions simultaneously. Third, support for overlaying...
We study the probability density function of the statistical fluctuations of the intensity scattered by an aggregate freely floating in space and constituted by Rayleigh particles under the dipole approximation. Its evolution as a function of the optical properties of the particles (polarizability) and their separation distance is analyzed. Aggregate geometries with two and three particles will be...
