... Based on the comparisons were made from the above table 1, our proposed hashsort method is occurred with 2 collisions and the existing linear probing method is occurred with 5 collisions. Hence it is proven, our ... See full document

... The proposed hybrid power system has two power sources: an FC and a battery system as an auxiliary source. The battery system is connected directly in parallel to the DC bus; its function is to enhance the peak power ... See full document
