IP Routers use sophisticated forwarding table (FIB) lookup algorithms that minimize lookup time, storage, and update time. This paper presents SMALTA, a practical, near-optimal FIB aggregation scheme that shrinks forwarding table size without modifying routing semantics or the external behavior of routers, and without requiring changes to FIB lookup algorithms and associated hardware and softwa...

The proper use of polymers as conditioners is a critical aspect of dewatering processes. In this study, we investigate their physical properties, i.e. size, density and fractal dimension and correlate them with their dewatering characteristics (bound water content, CST and SRF) on alum sludge with cationic polymer conditioning. Using CST measurement to determine the optimum polymer dose may lea...

Responses of wetland carbon cycling to environmental changes, particularly changes in water table depth, which are the key determinants to control the ecological and biogeochemical functions of wetlands, are highly non-linear and complex due to the dynamic interactions of several physical and biological processes. Several field experiments have found that wetland productivities have a significa...

a field study was conducted to evaluate the possibility of using water table control techniques in the semi arid region of iran with special attention to its salinity management. the wtm consisted of three subirrigation treatments with water table controls set at 0.3, 0.5 and 0.7 m from the soil surface and a free drainage (fd) treatment. the electrical conductivity (ec) of water was 1.5 ds/m. ...

groundwater drought denotes the condition and hazard during a prolonged meteorological drought when groundwater resources decline and become unavailable or inaccessible for human use. the aim of this study is to identify the influencial factors on groundwater drought in hamadan- bahar watershed,iran, to understand the forcing mechanisms. the standardised precipitation index (spi) has been used ...

In this study we investigate the effect of a water table boundary on solute spreading during infiltration in the vadose zone of heterogeneous soils. It has been found recently that the presence of the water table significantly affects unsaturated flow in a heterogeneous vadose zone and causes the flow to be spatially nonstationary. Because a vadose zone is by definition bounded by the water tab...
