Multiset concepts in two-universe approximation spaces

Abstract Rough set theory over two universes is a generalization of rough set model to find accurate approximations for uncertain concepts in information systems in which uncertainty arises from existence of interrelations between the three basic sets: verona wig objects, attributes, and decisions.In this work, multisets are approximated in a crisp

Impact of surface waves in a Regional Climate Model

A coupled regional atmosphere-wave model system is developed with the purpose of investigating the impact of climate changes on rectangular barn quilt patterns the wave field, as well as feed-back effects of the wave field on the atmospheric parameters.This study focuses on the effects of introducing a two-way atmosphere-wave coupling on the atmosp
