Improved real-space genetic algorithm for crystal structure and polymorph prediction [PDF]

open access: yesPhysical Review B 77, 134117 2008, 2008
Existing genetic algorithms for crystal structure and polymorph prediction can suffer from stagnation during evolution, with a consequent loss of efficiency and accuracy.

Species separation and modification of neutron diagnostics in inertial-confinement fusion [PDF]

open access: yes, 2014
The different behaviours of deuterium (D) and tritium (T) in the hot spot of marginally-igniting cryogenic DT inertial-confinement fusion (ICF) targets are investigated with an ion Fokker-Planck model.

Stagnation temperature measurement using thin-film platinum resistance sensors [PDF]

open access: green, 2013
The measurement of stagnation temperature in high-speed flows is an important aspect of gas turbine engine testing. The ongoing requirement to improve the accuracy of such measurements has led to the development of probe systems that use a thin-film ...
