BACKGROUND The Helicopter Emergency Medical Service (HEMS) in Norway is operated day and night, despite challenging geography and weather. In Western Norway, three ambulance helicopters, with a rapid response car as an alternative, cover close to 1 million inhabitants in an area of 45,000 km(2) . Our objective was to assess patterns of emergency medical problems and treatments in HEMS in a geog...

Recently, the provision of reserve from energy storage systems (ESSs) is introduced as a source for ancillary services to address uncertainties renewable power generations. The performance ESSs analysed while they are applied provider regulation reserves. It has been revealed that previous stochastic models neglect impact corrective dispatches, related reserves, on level stored in ESSs, which c...

In this paper, we analyze the ability of different auction structures to induce the efficient dispatch in a one-shot framework where generators know their own and competitors’ costs with certainty. In particular, we are interested in identifying which, if any, rules in an auction structure yield only the efficient dispatch in equilibrium. We find that a critical component to a successful auctio...

Instruction dispatch is responsible for most of the running time of Forth interpreters, especially on modern pipelined processors. Superinstructions are an important optimisation to reduce the number of instruction dispatches. Superinstructions have been used for many years to optimise interpreters, but an open problem is the choice of superinstructions to include in the interpreter. In this pa...

Instrumental Thin-Layer Chromatography (or Planar Chromatography) is a modern separation technique, established worldwide and distinguished by flexibility, reliability and cost efficiency. Together with HPLC and GC it belongs to the microanalytical methods, which play an important role in research and routine laboratories. In many cases instrumental Thin-Layer Chromatography offers a more suita...
