2014/3/13
With increasing usage of hardware accelerators in modern heterogeneous System-on-Chips (SoCs), the distinction between hardware and software is no longer rigid. The domain of cryptography is no except...
Enumeration of snakes and cycle-alternating permutations
snakes cycle-alternating permutations
font style='font-size:12px;'>
2010/11/9
Springer numbers are an analog of Euler numbers for the group of signed permutations. Arnol'd showed that they count some objects called snakes, that generalize alternating permutations. Hoffman estab...
Snakes and ladders: localized solutions of plane Couette flow
Snakes ladders plane Couette flow
font style='font-size:12px;'>
2010/4/7
We demonstrate the existence of a large number of exact solutions of plane Couette flow, which share the topology of known periodic solutions but are localized in space. Solutions of different size ar...
