Abstract: This paper suggests a system-theoretical way of modeling simple centrifugal pump systems from a control engineering point of view based on using lumped parameters. First, a basic nonlinear ...

Abstract: A Simulink/DriveSize based model for the hybrid speed and throttle control of a centrifugal pumping plant equipped with a variable speed drive is proposed in this paper. The model provides ...

A controversial plan to release 45,000 gallons of radioactive water into the Hudson River has been approved in court. A federal judge ruled in favor of New Jersey-based Holtec International, which ...
