The feasibility of automatically controlling water levels and deliveries on the Salt River Project SRP canal system through computer-based algorithms is being investigated. The proposed control system automates and enhances functions already performed by SRP operators, namely feedforward routing of scheduled demand changes, feedback control of downstream water levels, and flow control at check ...

This paper is based on analysis of a common source - common gate low noise transconductance amplifier (CS-CG LNTA). Conventional noise analyses equations are modified by considering to the low output impedance of the sub-micron transistors and also, parasitic gate-source capacitance. The calculated equations are more accurate than calculated equations in other works. Also, analyses show that th...

A lumped-parameter model is considered for openchannel networks that expresses the dynamic relationship, in terms of state space variables, between gate opening sections and stored water volume variations in the different canal reaches with respect to a reference configuration of uniform flow. A proce dure is suggested to approximate a real steady flow condition with an ideal uniform flow confi...

In this work, the design and analysis of new Level Shifter with Gate Driver for Li-Ion battery charger is proposed for high speed and low area in 180nm CMOS technology. The new proposed level shifter is used to raise the voltage level and significantly reduces transfer delay 1.3ns (transfer delay of conventional level shifter) to 0.15ns with the same input signal. Also, the level shifter with g...

In the ICSSDOM simulation-optimization model, simulated annealing algorithm is combined with a hydrodynamic simulation model named ICSS. In this model the ability of weighting of indicators is also considered. In this study, using this model the performance of the S-L-R5 canal in the DEZ irrigation network was evaluated in a period of 10 days. With presenting a proposed method for weighting the...
