Fun for Two

0 Fun for two

We performed populations synthesis calculations of single stars and binaries and show that binary evolution is extremely important for Galactic astronomy. We review several binary evolution models and conclude that they give quite different results. These differences can be understood from the assumptions related to how mass is transfered in the binary systems. Most important are 1) the fractio...

We design and implement three selfish-peer exploits and evaluate their effectiveness on public and private torrents. In practice, BitTorrent appears quite robust against this kind of exploit: selfish peers can sometimes obtain more bandwidth,...

Recently, two things have again droven the attention to this old horse. First, after more than a decade of work, DNS Security extensions (DNSSEC) have finally reached a level of maturity that deployment is in the...

We can illustrate each component of this definition with the example of home winemaking, in which the biological raw material is sugar and the biological catalyst is yeast. As the fermentation occurs, alcoho...
