abstract in all river engineering projects, determination of flow resistance is essential. most commonly, the manning roughness coefficient, , is used to describe the flow resistance or relative roughness of main channel or flood plane. over the past decades little or no study has been conducted to investigate the effects of particle shapes on manning roughness coefficient. therefore, it is the...

We consider a macroion confined to a cylindrical cell and neutralized by oppositely charged counterions. Exact results are obtained for the two-dimensional version of this problem, in which ion-ion and ion-macroion interactions are logarithmic. In particular, the threshold for counterion condensation is found to be the same as predicted by mean-field theory. With further increase of the macroio...

Manning [1] presents an extended critique of a paper by Zaenen, Karttunen and Crouch [2] (henceforth ZKC), which was a commentary on the PASCAL Recognizing Textual Entailment (RTE) challenge [3]. The ZKC paper was entitled “Local textual inference: can it be defined or circumscribed?” and argued that the PASCAL data should have been better defined and circumscribed so as to distinguish between ...

An intelligent method based on adaptive neuro-fuzzy inference system (ANFIS) for identifying Manning’s roughness coefficients in modeling of alluvial river is presented. The procedure for selecting values of Manning n is subjective and requires judgment and skill which are developed primarily through experience. During practical applications, researchers often find that a correct choice of the ...

We present solutions of the Schrodinger equation with superposition Manning-Rosen plus inversely Mobius square quadratic Yukawa potentials using parametric Nikiforov Uvarov method along an approximation to centrifugal term. The bound state energy eigenvalues for any angular momentum quantum number l and corresponding un-normalized wave functions are calculated. mixed potential which in some par...

The Manning friction coefficient as a one-dimensional (1D) openchannel flow parameter is determined from a series of two-dimensional (2D) simulations of the flow on steep slopes using a computational hydraulic solver derived from a minimal intervention strategy (MIS2D). Computations are also conducted for the oblique dam-break waves to evaluate the performance of MIS2D. The results are compared...
