We present a collision attack on the hash function HAS-160 reduced to 53-steps. The attack has a complexity of about 2 hash computations. The attack is based on the work of Cho et al. presented at ICISC 2006. In this article, we improve their attack complexity by a factor of about 2 using a slightly different strategy for message modification in the first 20 steps of the hash function.

Class C physiologic incident reports during undergraduate pilot training (UPT) revealed that 1.7 episodes of G-induced loss of consciousness (LOC) occurred monthly in 1980-1984. The mean +Gz for the LOC episodes was +3.8 Gz; the minimum, +2.0 Gz. The mean time of total incapacitation was 12.0 s (maximum, 180.0 s) as subjectively estimated by the aircrew. Improper performance of the anti-G strai...

Searching for educational resources on the web would be greatly facilitated by the availability of classificatory metadata, but most web educational resources put up by faculty members provide no such metadata. We explore using text classification and information extraction techniques to automatically gather such metadata. Text classifications orthogonal to topic matter appear possible with hig...
