Manhole cover is an important device of urban drainage infrastructures. The hydraulic characteristics turbine-type manhole covers were studied through numerical simulations and physical experiments. flow field water surface investigated. process divided into two parts: free regime submerged regime. Numerical experimental results are in good agreement. It indicated that the depth constant later ...

This work presents a comparison study between the state-space and polynomial methods for the design of the robust governor for load frequency control of steam turbine power systems. The robust governor is synthesized using the two approaches and the comparison is extended to include time and frequency domains performance, controller order, and uncertainty representation, weighting filters, opti...

In the management of water distribution networks, large energy savings can be yielded by exploiting the head drop due to the network pressure control strategy, i.e., for leak reductions. Hydropower in small streams is already exploited, but technical solutions combining efficiency and economic convenience are still required. In water distribution networks, an additional design problem comes out...
