Aerodynamic forces on high speed multi-hulled marine vehicles [PDF]
, 2008 The need for high-speed high-payload craft has led to a considerable interest in vehicles capable of bridging the gap between conventional ships and aircraft. One such concept uses the forward motion of the craft to create aerodynamic forces on a wing-

High-speed high-security signatures [PDF]
Journal of Cryptographic Engineering, 2011 This paper shows that a $390 mass-market quad-core 2.4GHz Intel Westmere (Xeon E5620) CPU can create 108000 signatures per second and verify 71000 signatures per second on an elliptic curve at a 2128 security level. Public keys are 32 bytes, and signatures are 64 bytes.

Speed in a high-speed society [PDF]
International Journal of Injury Control and Safety Promotion, 2019 Speed control is the most important aspect of promoting road safety world-wide. The question is how are speeds developing? The European Transport Safety Council concludes: There is little progress on reducing speeds in Europe. Similar conclusions can be drawn from the US and Australia. Attitude surveys show that people's answers are not very consistent
