In the separate universe approach, an inhomogeneous is rephrased as a set of glued numerous homogeneous local patches. This essence gradient expansion and δN formalism, which have been widely used in solving long wavelength evolution universe. this paper, we show that approach can be generically used, theory under consideration preserves spatial diffeomorphism invariance. Focusing on these two ...

the benefits of using mineral admixtures as a partial replacement of portland cement (pc) are well established in the literature. economic and environmental advantages by reducing co2 emissions are well known. this paper examines the influence of intergrinding and separate grinding on the amount of energy consumption, blaine fineness and particle size distribution (psd) of blended cements, name...

today, dc motors is still being used globally due to their easy speed controllability. in this article, an adaptive neuro-fuzzy inference system (anfis) controller is designed for dc motors. the main purpose of performing such task is to reduce the dc motor starting current and deleting the ripple current during starting time in considering control parameters such as: rise time, settling time, ...
