slow sand filtration (s.s.f) is a main process in the water treatment technology and generally considered as most appropriate for application in rural and small urban areas in developing countries. however, performance of the s.s.f is very sensitive to high turbidity levels. therefore, pretreatment is necessary for such waters. horizontal - flow roughing filtration (hfrf) and direct horizontal ...

Filtration index of the drilling fluid is an important parameter of well drilling, especially at drilling-in the reservoirs. Standard parameter in the study of drilling fluids is static filtration index. At the same time, it is more feasible to determine dynamic filtration index, if considering actual conditions of the well. Use of polymer carbonate-weighted drilling fluids is advisable at dril...

The majority of popular graph kernels is based on the concept Haussler's R-convolution kernel and defines similarities in terms mutual substructures. In this work, we enrich these similarity measures by considering filtrations: Using meaningful orders set edges, which allow to construct a sequence nested graphs, can consider at multiple granularities. A key our approach track features over cour...
