This paper sketches an approach to learn interdependencies between multiple time series. At the beginning the time series are segmented and thereby transformed into sequences of labeled intervals. The labels denote qualitative aspects of the signal in the respective intervals. Then, from the sequence of labeled intervals, we discover rules where premise and(More)
A time course study was carried out to assess the appearance and distribution of DON in different organs of forage maize cultivated in the field. DON was produced after the flowering period and increased until harvest to high amounts in the rudimentary ears and leaf sheaths/leaf blades deriving from nodes located below the ear node, whereas nodes and(More)
The deoxynivalenol contents of forage maize in this study ranged between 0.22 and 12.9 mg/kg DM, but seldom exceeded critical concentrations suggested for ruminant diets. Zearalenone was found in considerably lower concentrations than DON and rarely reached critical levels. Therefore risk to the health and performance of ruminants is regarded as low.(More)
Fertilization with biogas residues from the digestion of energy crops is of growing importance. Digestate from silage maize (Zea mays L.) is a new fertilizer with a high potential for ammonia (NH3) and nitrous oxide (N2O) emission. The aim of this study was to determine the effect of different maize fertilization systems [180 kg N ha−1 in form of calcium(More)
Introduction. When dealing with time series, the application of a smoothing filter (to get rid of random fluctuations and better recognise the relevant structure) is usually one of the first steps. In the literature on time series similarity measures, however, the impact of smoothing is not explicitly or systematically considered – despite extensive(More)
Infections of maize with phytopathogenic and toxinogenic Fusarium spp. may occur throughout the cultivation period. This can cause different types of diseases in vegetative and generative organs of the plant. Along with these infections, mycotoxins are often produced and accumulated in affected tissues, which could pose a significant risk on human and(More)
