The Neolithic was marked by a transition from small and relatively egalitarian groups, to much larger groups with increased stratification. But the dynamics of this remain poorly understood. It is hard to see how despotism can arise without coercion... Read More about An evolutionary model explaining the Neolithic transition from egalitarianism to leadership and despotism..

PCA-ANFIS based prediction for water Injection effectiveness cycle in oil fields. (2014)
Journal Article

By proposing a numerical based method on PCA-ANFIS(Adaptive Neuro-Fuzzy Inference System), this paper is focusing on solving the problem of uncertain cycle of water injection in the oilfield. As the dimension of original data is reduced by PCA, ANFIS... Read More about PCA-ANFIS based prediction for water Injection effectiveness cycle in oil fields..
