Investigation of Fresh Water Harvesting from Playa’s Wetlands
Playas are low-lands which is considered to be the locations of accumulation of superficial and ground waters fromhigher elevations and these waters have different types of salts and various salinity level. Therefore, because of lack ofrainfall and fresh-water both for human and animal useage or even for plants, it is needed to apply proper methods toharvest fresh water from these saline-waters...

متن کاملHarvesting energy from the marine sediment--water interface.
Pairs of platinum mesh or graphite fiber-based electrodes, one embedded in marine sediment (anode), the other in proximal seawater (cathode), have been used to harvest low-level power from natural, microbe established, voltage gradients at marine sediment-seawater interfaces in laboratory aquaria. The sustained power harvested thus far has been on the order of 0.01 W/m2 of electrode geometric a...

متن کاملExtracting Roads from Ikonos Images
Remote sensing has been used mostly to produce analyses on different aspects and phenomena concerning territory. The approach is not different from the one employed when analysing maps in the sense that analysis depends on the nature of data, maps and satellite images being two different sources of spatial data. Obviously, analysis based on cartographic data is different from the one based on s...
