A methodology for the development of a fuzzy expert system (FES) with application to earthquake prediction is presented. The idea is to reproduce the performance of a human expert in earthquake prediction. To do this, at the first step, rules provided by the human expert are used to generate a fuzzy rule base. These rules are then fed into an inference engine to produce a fuzzy inference system...

Each closed oriented 3-manifoldM is naturally associated with a set of integersD(M), the degrees of all self-maps on M . D(M) is determined for each torus bundle and torus semi-bundle M . The structure of torus semi-bundle is studied in detail. The paper is a part of a project to determine D(M) for all 3-manifolds in Thurston’s picture.

Abstract Previous investigation of seismic anisotropy indicates the presence a simple mantle flow regime beneath Turkish-Anatolian Plateau and Arabian Plate. Numerical modeling suggests that this is component large-scale global associated with African superplume, which plays key role in geodynamic framework Arabia-Eurasia continental collision zone. However, extent impact pattern farther east I...
