In this study, we develop a saturation-dependent treatment of dispersion in porous media using concepts from critical path analysis, cluster statistics of percolation, and fractal scaling of percolation clusters. We calculate spatial solute distributions as a function of time and calculate arrival time distributions as a function of system size. Our previous results correctly predict the range ...

in this present study the dissolved air flotation (daf) system was investigated for the treatment of kermanshah oil refinery wastewater. the effect of three parameters on flotation efficiency including of flow rate (outflow from the flotation tank), saturation pressure and coagulant dosage on chemical oxygen demand (cod) removal was examined experimentally. all the experiments were done under a...

This article addresses the cooperative fault-tolerant control problem for networks of stochastic nonlinear systems with actuator faults and input saturation. The fuzzy neural (FNNs) are employed to estimate unknown functions disturbance terms. To analyze nondifferential saturation nonlinearity, a smooth function signal is constructed function. A novel adaptive protocol proposed by using backste...

ÐThe performance analysis of dynamic routing algorithms in interconnection networks of parallel computers has thus far predominantly been done by simulation studies. A limitation of simulation studies is that they usually only hold for specific combinations of network, routing algorithm, and traffic pattern. In this paper, we derive saturation point results for the class of homogeneous traffic ...

A method is presented for the steady-state analysis of universal motors operating under direct or alternating voltage sources, and in the presence of saturation of the iron in the magnetic circuit. The saturation is modelled through a completely general functional dependence of the air-gap flux on the current, thus resulting in a unified treatment for various saturation models. It is shown that...

DIS data from HERA show a striking regularity as σγ p is a function of the ratio τ = Q/Qs(x) only. The scaling function shows a break at τ ≈ 1, which has been taken as an indication for saturation. However, besides saturation also the transition between dominance of k⊥-ordered (DGLAP) and k⊥-non-ordered (BFKL) evolution contributes to a break around this value of τ , as well as the suppression ...

This paper investigates the local stabilization problem of delayed fractional-order neural networks (FNNs) under influence actuator saturation. First, sector condition and dead-zone nonlinear function are specially introduced to characterize features saturation phenomenon. Then, based on Lyapunov method estimation technique Mittag–Leffler function, an LMIs-based criterion is derived guarantee s...
