in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
This study presents an evaluation of the relative efficiency of sixteen container ports in Sub-Sahara Africa using three DEA models namely CCR, BCC and Super-Efficiency over the year 2012. The CCR and BCC models are used to estimate the technical and scale efficiency while the super-efficiency technique provides a ranking of efficient ports. The efficiency results indicate that on average the i...
