1. INTERFERENCE OF THE NUMBER OF REMOTE CONTROL VALVES IN USE ON THE ENERGY PERFORMANCE OF AN AGRICULTURAL TRACTOR WITH PRODUCTIVITY MANAGEMENT
ABSTRACT The hydraulic remote control system allows the transfer of energy from the engine through a flow of hydraulic oil to engines and implements pulled by agricultural tractors, which can interfere with its energy and operational performance. This study aimed to evaluate the interference of the number of remote control valves in use on the operational an

5. Development and evaluation of a range anxiety - reducing business model for connected full electric vehicles
This thesis develops and evaluates a business model for connected full electric vehicles (FEV) for the European market. Despite a promoting political environment, various barriers have thus far prevented the FEV from becoming a mass-market vehicle. Besides cost, the most noteworthy of these barriers is represented by range anxiety, a product of FEVs’ limit
