This paper presents the construction, mathematical modeling and testing of a scaled universal hydraulic Power Take-Off (PTO) device for Wave Energy Converters (WECs). A specific prototype and test bench were designed and built to carry out the tests. The ... see more

Constructed ponds and wetlands are widely used in urban areas for stormwater management, ecological conservation, and pollution treatment. The treatment efficiency of these systems is strongly related to the hydrodynamics and hydraulic residence time. In ... see more

In this work presents the modeling and simulation of a braking energy regeneration system in a hydraulic hybrid vehicle. The vehicle used for testing is a 15000 kg heavy duty truck. The proposed regeneration system configured in parallel was subjected to ... see more
