the performance of water flooding can be investigated by using either detail numerical modeling or simulation, or simply through the analytical buckley-leverett (bl) model. the buckley-leverett analytical technique can be applied to one-dimensional homogeneous systems. in this paper, the impact of heterogeneity on water flooding performance and fractional flow curve is investigated. first, a ba...

since the surface water is one of the main potable water resources, the usage of chlorine as a disinfectant has increased. consequently the production rate of disinfection by-products (dbps) such as trihalomethane (thm) compounds has grown dramatically. in this paper the thms concentration changes in the sangar water treatment plant (swtp) and rasht water distribution system (rwds) is presented...

We investigate a Larson-type model of a ternary mixture of nonionic amphiphiles, water and oil confined between walls or forming a membrane by performing Monte Carlo simulations on a cubic lattice. We compute the concentration profiles of water foil and the distribution of the amphiphiles with varying temperatures and distance from a solid wall. For temperatures below the critical temperature f...

Human knee joint menisci graded according to degenerative alterations were submitted to chemical analysis. Normal menisci contained 72% water, 0.12% DNA, 22% collagen, and 0.8% total glycosaminoglycans with the following glycosaminoglycan distribution pattern: 40% chondroitin 6-sulphate, 10-20% chondroitin 4-sulphate, 20-30% dermatan sulphate, and 15% keratan sulphate. The water content increas...

This paper presents a multi-model predictor called Qualitative Multi-Model Predictor Plus (QMMP+) for demand forecast in water distribution networks. QMMP+ is based on the decomposition of the quantitative and qualitative information of the time-series. The quantitative component (i.e., the daily consumption prediction) is forecasted and the pattern mode estimated using a Nearest Neighbor (NN) ...

Methods of modifying the water distribution pattern of an impact-drive sprinkler are described. A method of pattern modification called intermittent diffusion is introduced. A deflector attached to the drive arm intermittently diffuses the jet of a standard circular-orifice nozzle, producing desirable pattern shapes while maintaining a large pattern radius. Uniformity of application for both wi...
