Nigeria is a major rice-producing and rice-importing country in Africa, challenged with ensuring rice-food security for its growing population. Successive governments have implemented several strategies to increase local rice production such as import restriction policies agricultural investments. These yielded results but achieving long-term sustainable growth Nigeria’s agri-food system has re...

In this paper the concept of a fuzzy contraction mapping on a fuzzy metric space is introduced and it is proved that every fuzzy contraction mapping on a complete fuzzy metric space has a unique fixed point.

In light of recent research and empirical findings a new view on emotion and affect has surfaced. Within this view ‘feeling’ (core affect) is separated from ‘emotion’ (psychological construction). This model appears to be a good candidate for a computation model of affect and emotion. We argue that fuzzy logic is the perfect tool for its implementation, for the modeling of core affect dynamics,...

in this paper, we shall introduce the fuzzyw-distance, then prove a common fixed point theorem with respectto fuzzy w-distance for two mappings under the condition ofweakly compatible in complete fuzzy metric spaces.
