If the rain decreases, the buoy drops at the same speed -as the cylindrical reservoir empties. The pluviometer recorded precipitation in Barcelona for 95 years and in places such as Hong-Kong). To measure the average intensity of rainfall in a certain interval of time, the Pluviometer of intensities uses the formula: Intensity varies over time. The pluviometer records instantaneous rain intensity (as its name defines): Ramón Jardí i Borrás Ramon Jardí i Borras (Tivissa, November
Klee's measure problem given a collection of "n" "d"-dimensional rectangular ranges, compute the measure of their union. This general problem is Klee's measure problem. When generalized to the "d"-dimensional case, Bentley's algorithm has a running time of formula_3. This turns out "not" to be optimal, because it only decomposes the "d"-dimensional problem into "n" ("d-1")-dimensional problems, and does not further decompose those subproblems. In 1981, Jan van Leeuwen and Derek Wood improved the running time of this algorithm to formula_4 for "d" ≥ 3 by using dynamic quadtrees. In 1988, Mark Overmars and Chee Yap proposed an formula_5 algorithm for "d" ≥ 3.
