To answer with a statement of purpose—e.g., to say the sky is blue in order to make people happy—would not cross the scientifi c mind. Yet in biology we often pose " why " questions in which it is purpose, not mechanism, that interests...

15 صفحه اولParallel Forward Deduction Algorithms of General-Purpose Entailment Calculus on Shared-Memory Parallel Computers
An automated forward deduction system for entailment calculus is an indispensable component of many application systems – such as theorem finding, active database, knowledge discovery systems – that require an autonomous reasoning engine. The performance of an automated forward deduction system is crucial to its applicability. In this paper, we present some parallel forward deduction algorithms...

15 صفحه اولA Nonlinear Creep-damage Constitutive Model of Mudstone Based on the Fractional Calculus Theory
During the flood development in an oil field, the creep characteristic of mudstone is one of the important factors causing casing damage. In this study, based on the theory of fractional order differential and taking into account the creep damage evolution rules, a fractional nonlinear creep-damage model is proposed to reflect the instantaneous deformation in loading processes and the accelerat...
