Measurement studies have shown that real world BitTorrent (BT) systems exhibit high seed capacity. Thus, appropriate use of seed capacity can have a significant effect on BT performance. Moreover, seed capacity is also easily exploitable by free-riders, and such free-riding clients exist out in the wild today. In this paper, we propose a simple and scalable approach that makes more intelligent ...

The gaze behaviour of riders during their approach to a jump was investigated using a mobile eye tracking device (ASL Mobile Eye). The timing, frequency and duration of fixations on the jump and the percentage of time when their point of gaze (POG) was located elsewhere were assessed. Fixations were identified when the POG remained on the jump for 100 ms or longer. The jumping skill of experien...
