Kwang-Il Goh, Albert-Laszlo Barabasi: Burstiness and Memory in Complex Systems
The dynamics of a wide range of real systems, from email patterns to earthquakes, display a bursty, intermittent nature, characterized by short timeframes of intensive activity followed by long times of no or reduced activity. The understanding of the origin of such bursty patterns is hindered by the lack of tools to compare different systems using a common framework. We introduce two measures to distinguish the mechanisms responsible for the bursty nature of real signals, changes in the interevent times and memory. We find that while the burstiness of natural phenomena is rooted in both the interevent time distribution and memory, for human dynamics memory is weak, and the bursty character is due to changes in the interevent time distribution. Finally, we show that current models lack in their ability to reproduce the activity pattern observed in real systems, opening up new avenues for future work.

Mina två stora favoritfinesser i 2.0:an är:
1) Tar mindre mindre. Eller snarare: man behöver inte starta om programmet så ofta för att det slukar för mycket minne efter ett tag.
2) Den svenska stavningskontrollen.
Om svensk sådan saknas: högerklicka i ett textfält och välj Languages, Add dictionaries och installera det svenska. Vill man ha svenska som standardval så väljs det också via högerklick-menyn.
