In this study, an artificial neural network (ANN) was applied to predict the performanceof two rotating biological contactor (RBC) systems in removal of hydroquinone (a toxic aromaticcompound). The first system was a ...

In this paper, by using depth-averaged equations, three different dispersion models forsimulating flow at channel bends are presented and compared. Two of these models employ powerlaw velocity distributions for longitudinal ...

Hydrodynamics of open channel confluences is very complicated. Simulation of rightangledchannel confluences using a recently-developed 2D high-resolution model is presented inthis paper. Finite-volume discretization of ...

Two-dimensional diffusive and advective-diffusive chloride transport through clay andsilt, respectively, was investigated using laboratory models. The observed chloride concentrationplumes in the soil samples as well as ...

Doroodzan dam is a 57m high earth dam with rip-rap cover constructed on Kor River inBakhtegan Basin. The dam is located at 30° 12' 2'' north latitude and 52°25' 5'' east longitude~70km north of Shiraz, Iran. The dam reservoir ...

This paper investigates the performance of a multiple-deme genetic algorithm (GA)with modified reproduction operators, in optimal design of planar steel frames according to theAISC-LRFD specification. The design objective ...

In this paper, structures transformable to regular forms are studied. Here, two cases areinvestigated. In the first case, the effect of different boundary conditions on these structures areexplored, and in the second case ...
