Here we present first observations, from in-strumentation installed on moorings and a float, of unexpectedly low (< 2 µmol kg −1) oxygen environments in the open waters of the tropical North Atlantic, a region where oxygen concentration does normally not fall much below 40 µmol kg −1. The low-oxygen zones are created at shallow depth, just below the mixed(More)
This paper describes the work that is being done within the EU research project DISASTER to solve interoperability issues in cross-border emergency operations by applying a technical solution that is able to create a common operational picture. To that end a twofold solution is proposed: the development of a common and modular ontology shared by all the(More)
– For high performance speed and position control of electrical drives fast online identification is needed for time-varying inertia or load conditions in combination with adaptive controllers. In this paper Extended Kalman Filters are applied and optimized for deterministic parameter variations by integrating basis function networks into the common(More)
m Automobile exhaust was sampled at 1 liter per minute through a water trap and two bubblers in series. The bubblers contained aqueous acidified 2,4-dinitrophenylhydrazine (2,4-DNP). The carbonyl compounds in the water trap were precipitated with the hydrazine reagent. The hydrazones in the trap and in the bubblers were collected by filtration and(More)
