Uncertainties in s-process nucleosynthesis in massive stars determined by Monte Carlo variations [PDF]
, 2017 The s-process in massive stars produces the weak component of the s-process (nuclei up to A ∼ 90), in amounts that match solar abundances. For heavier isotopes, such as barium, production through neutron capture is significantly enhanced in very metal ...

What makes a good process model? Lessons learned from process mining [PDF]
, 2012 There seems to be a never ending stream of new process modeling notations. Some of these notations are foundational and have been around for decades (e.g., Petri nets).

Dynamic failure analysis of process systems using neural networks [PDF]
, 2017 Complex and non-linear relationships exist among process variables in a process operation. Owing to these complex and non-linear relationships potential accident modelling using an analytical technique is proving to be not very effective.
