However, this law only predict the average time for pointing the target with a given difficulty. In this paper, we propose to use a fuzzy regression approach, named imprecise regression, which allows us to predict the general(More)

While there is an agreement on the definition of what a static distributed system is, there is no agreed definition on what a dynamic distributed system is.
