In the Manning equation the hydraulic radius can be defined as the cross-section dimension of the shape. In pipe flow the bed shear stress is assumed to be uniformly distributed along the wetted perimeter which cannot be true in open channel flow. Hence, three approximation of the true boundary shear-stress distribution are examined and more practical conveyance depth or resistance radius formu...

in this paper, collapse behavior of simple and reinforced thin-walled channel- section beams, subjected to three- point bending, is investigated. many simple channel- section beams of different geometry and some reinforced ones were tested, and their strengths after collapse were obtained thoroughly. since the available theories in this area are complicated and little attention has been paid to...

construction of the intake structures to divert some portion of flow water from a main channel causes some variations of flow conditions at the intake entrance. these variations cause the reinforcement of the eddy flow and sedimentation in the bank of the intake. an effective measure to control the entry sediment is the use of submerged vanes. most of previous studies in this regards have been ...

The top quark, which completes the quark sector of the SM, was discovered in 1995 at the Tevatron by the CDF and DØ Collaborations [1]. Being the heaviest of all quarks with a mass of 178.0 ± 4.3 GeV/c [2], it couples most strongly to the Higgs boson, and its lifetime of ≈ 4 · 10 s means that it is the only quark that decays before it can hadronise, preserving spin information, and providing a ...

In this paper, we have carried out a numerical simulation of FinFETs. The model is based on 1D non-equilibrium Green’s function (NEGF) along the channel and 2-D Schrödinger equation in the confined cross section and provides insights into the performance of FinFETs with ultra small channel cross section. The simulation results of FinFETs show normal I-V characteristics with great potential in s...
