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
Gibbs measure property. Measures with this property are sometimes called Markov random fields. More strongly, the converse is also true: "any" positive probability distribution (nonzero density everywhere) having the Markov property can be represented as a Gibbs measure for an appropriate energy function. This is the Hammersley–Clifford theorem. What follows is a formal definition for the special case of a random field on a lattice. The idea of a Gibbs measure is, however, much more general than this. The definition of a Gibbs random field on a lattice requires some terminology: We interpret as the contribution to the total energy (the Hamiltonian)
