In this paper, the noise equivalent power (NEP) of an optical sensor based ongraphene-superconductor junctions in the constant current mode of operation has beencalculated. Furthermore, the necessary investigations to optimize the device noise withrespect to various parameters such as the operating temperature, magnetic field, deviceresistance, voltage and current bias have been presented. By s...

Flooding due to the failure of drainage systems is a serious problem for many urban watershed of Iran. This paper shows how flooding in urban drainage systems can be simulated by one- dimensional hydrodynamic modeling incorporating the interaction between (I) the buried pipe systems (II) the streets with open channel flow. The values of the NS, RMSE, and %BIAS statistics were also calculated to a...
