Optimization of a simple LNG process using sequential quadratic programming

The efficiency of using sequential quadratic programming (SQP) for the optimization of a PRICO process for the production of liquefied natural gas (LNG) is demonstrated. Most of the returned objective values have been better, and the execution times much lower, than in most previously published work on similar optimization cases. The optimization runs discussed in this paper require around 5 min of execution time.acceptedVersio

Neutrino Interactions In Oscillation Experiments

We calculate neutrino induced cross-sections relevant for oscillation experiments, including the $\tau$-lepton threshold for quasi-elastic, resonance and deep inelastic scattering. In addition to threshold effects, we include nuclear corrections for heavy targets which are moderate for quasi-elastic and large for single pion production. Nuclear effects for deep inelastic reactions are small. We present cross sections together with their nuclear corrections for various channels which are useful for interpreting the experimental results and for determining parameters of the neutrino sector..Comment: 24 pages, 18 figure

Forms of participation – the development and application of a conceptual model of participation in work environment interventions

In the realm of work environment improvements, the Nordic countries have led the way in demonstrating that employee participation is a key requisite for achieving improvements. Despite this there is a lack of precision on what ‘participatory’ in a participatory work environment intervention means. In this study, we present a conceptual model for participation in work environment interventions and apply it to protocols and manuals from 8 participatory interventions to determine the form of participation used in each intervention. We suggest that the conceptual model can be applied in the design and assessment of participatory work environment interventions
