A systematic method is proposed to approach complete fault coverage for catastrophic faults in analog circuits. In the proposed method, a fault propagation graph is first created from the circuit netlist. Standard graph theory techniques are then employed to identify a minimal set of observation points (MOP) such that, by monitoring these points, complete fault coverage can be achieved, i.e., all...
The north of Jiaozhou Bay has become the important region for the development strategy of Qingdao in China, because the development space of the old city district gets saturated. The Moshui River will become the main contaminated river of this area. Neural network was used to build the water quality prediction model of the discharge outlet of the river to predict the concentration of COD, ammonia...
This research investigated the distribution of eutrophication degree in Nansi Lake using remote sensing data. Nine sampling points were monitored with Chla, TP and TN three parameters in upper lake of Nansi Lake. TSI of each sampling points was calculated using Carlsonpsilas TSIM. Then the linear model between remote sensing data and TSIM of each field monitoring points in upper lake of Nansi Lake...
This research investigated the distribution of Chlorophyll-a and suspended substance (SS) in Nansi Lake using remote sensing data. The correlation between the Landsat5 TM data and the field measurement for water quality was analyzed using Pearson distribution theory. The remote sensing inversion model of Chlorophyll-a and SS in Nansi Lake as indexes of water quality were also established.
