ABSTRACT- Measurement of irrigation water in agricultural areas is necessary, especially, in arid and semi-arid regions. Long-throated flumes have been used to measure irrigation water and are known to be inexpensive devices with high performances. In these structures, head-discharge tables are predicted theoretically with no need to calibrate. In this study, the model of LOTF ...

to estimate the fish composition and catchability coefficient of gillnet, a survey was carried out during april 2011 to march 2012 in the shadegan wetland, khuzestan province, iran. samples were collected from five stations viz., mahshar, rogbe, khorosy, ‍salmane and atish. approximately 4300 fish specimens were measured and depletion method was used for the estimation of catchability coefficie...

We introduce a nonlinear variant of the voter model, the q-voter model, in which q neighbors (with possible repetition) are consulted for a voter to change opinion. If the q neighbors agree, the voter takes their opinion; if they do not have a unanimous opinion, still a voter can flip its state with probability epsilon . We solve the model on a fully connected network (i.e., in mean field) and ...
