Background: Continuous expansion of potable water pollution sources is one of the main concerns of water suppliers, therefore measures such as water safety plan (WSP), have been taken into account to control these sources of pollution. The aim of this study was to identify probable risks and threatening hazards to drinking water quality in Lighvan village along with assessment of bank filtratio...

accumulation of trace metals in sediment can cause severe ecological impacts. the present study determines the elemental concentrations and chemical partitioning of heavy metals in surface sediment of shadegan wetland. shadegan wetland is one of the most important wetlands in southwest of iran and it is in ramsar-listed wetlands. for this purpose, 7 sampling stations were selected for sediment ...

Classifying novel terrain or objects from sparse, complex data may require the resolution of conflicting information from sensors working at different times, locations, and scales, and from sources with different goals and situations. Information fusion methods can help resolve inconsistencies, as when evidence variously suggests that an object’s class is car, truck, or airplane. The methods de...
