When the uncertainty corresponding to each source is provided via the probability of a single unconditional event, standard probability and statistics techniques are adequate for dealing with the problem. However, it often arises that uncertainty is not provided in such a format.

rized briefly. It was realized by Bishop (1967) that a constructive proof of an existential statement is an algorithm for computing a witness of this statement. Furthermore, a specification of a functional program can be thought of as an existential proposition which may have parameters. The potenti作者: agenda 時(shí)間: 2025-3-24 02:42
r obtaining good average behavior, for instance in distributed computing. Proving properties of such algorithms requires subtle reasoning both on algorithmic and probabilistic aspects of the programs. Providing tools for the mechanization of reasoning is consequently an important issue. Our paper pr作者: 特別容易碎 時(shí)間: 2025-3-24 08:57
grams they employ coinduction, per perhaps less enthusiastically. Coinduction is often considered as a rather low-level proof method, especially, as it seems to depart rather radically from equational reasoning. In this talk we introduce an alternative proof technique based on unique fixed points.

Effective Precipitation,tural precipitation. Hence, precipitation needs to be measured (Fig. 3.1). Not all precipitation infiltrates into the soil; a part may evaporate; another part may become surface runoff. Of the precipitation that infiltrates, only a part will be stored in the root zone and the remainder will recharge作者: Myosin 時(shí)間: 2025-3-25 07:34 作者: cultivated 時(shí)間: 2025-3-25 15:07

Despite all the good that has come out of this devel- opment, however, there have been misuses because the theory has been used mainly as a tool or a procedure by many applied workers without fully understanding its underlying mathematical workings.
