Energy harvesting from vehicular traffic over speed bumps: A review [PDF]

open access: yes, 2018
Energy used by vehicles to slow down in areas of limited speed is wasted. A traffic energy-harvesting device (TEHD) is capable of harvesting vehicle energy when passing over a speed bump. This paper presents a classification of the different technologies

Energy-efficient control of pump units based on neural-network parameter observer [PDF]

open access: yes, 2020
An observer based on an artificial neural network was designed. The observer determines the pumping unit performance depending on the operating point. Determination is based on the measured technological coordinates of the system and the pressure of the ...

Characterization of Hydraulic Power in Free-Stream Installations

open access: yesInternational Journal of Rotating Machinery, 2017
The performance of open-channel hydropower devices can be optimized by maximizing the product of their load, hydraulic, and generator efficiencies. The maximum hydraulic power theoretically available must be defined according to the operational scenario ...

A Model for Selecting the Most Cost-Effective Pressure Control Device for More Sustainable Water Supply Networks [PDF]

open access: yes, 2019
Pressure Reducing Valves (PRV) have been widely used as a device to control pressure at nodes in water distribution networks and thus reduce leakages. However, an energy dissipation takes place during PRV operation.
