Hace 1 día · The van der Waals equation, named for its originator, the Dutch physicist Johannes Diderik van der Waals, is an equation of state that extends the ideal gas law to include the non-zero size of gas molecules and the interactions between them (both of which depend on the specific substance). As a result the equation is able to model the phase change, liquid vapor.
Hace 1 día · Nuclear fusion is a reaction in which two or more atomic nuclei, usually deuterium and tritium (hydrogen isotopes), combine to form one or more different atomic nuclei and subatomic particles (neutrons or protons).The difference in mass between the reactants and products is manifested as either the release or absorption of energy.This difference in mass arises due to the difference in nuclear ...
Hace 29 minutos · and has the following properties. The function is infinitely smooth and monotonic. The range of the function is \((-1,1)\), i.e., the function is bounded.Note that it maps zeros input to zero, while pushing positive (negative) inputs to \(+\) 1 (−1).. Similar to the logistic function, the derivative of tanh quickly decays to zero away from \(\xi =0\) and can thus lead to slow training.
Hace 1 día · Biodiversity is commonly measured in terms of taxonomic richness of a geographic area over a time interval. In order to calculate biodiversity, species evenness, species richness, and species diversity are to be obtained first. Species evenness [209] is the relative number of individuals of each species in a given area.
