During service, civil turbofans experience environmentally induced deterioration. Predicting this in a digital service twin model is computationally challenging due to the need to model both deterioration mechanisms and environmental conditions. For

Current state-of-the-art engine condition monitoring is based on a minimum of one steady-state data point per flight. Due to the scarcity of available data points, there are difficulties distinguishing between random scatter and an underlying fault i

Aircraft engine condition monitoring is a key technology for increasing safety and reducing maintenance expenses. Current engine condition monitoring approaches use a minimum of one steady-state snapshot per flight. Whilst being appropriate for trend

The severity of a flight mission depends on a wide range of operating conditions caused by aircraft, pilot and engine control system interaction. However, today’s availability of continuously sampled data offers the chance to relate the severity of

The research results of the Lake Project Mecklenburg-Western Pomerania allow an assessment of the trophic situation of the lakes of the north-eastern federal state of Germany. As a result, the trophic state of the majority of the lakes is higher than

The seasonal changes of the abundance and biomass of protozooplankton were investigated by a live-counting technique in the mesoeutrophic Lake Neumuhler See. In addition, the biomass of metazoans and phytoplankton was studied. During the annual cycle
