Common Unique Fixed Point Theorem for Random Operators in Hilbert Space

The object of this paper is to obtain a common fixed point theorem for four continuous random operators by considering a sequence of measurable functions satisfying certain contractive condition in separable Hilbert space. Keywords: Separable Hilbert space, random operators, common random fixed point, rational inequality.

LEDESS - Nederland : modelconcept, databestanden en kennistabellen voor standplaats- en vegetatiemodules voor een landschapsecologisch beslissingsondersteunend systeem voor nationale verkenningen

Voor nationale natuur- en milieuverkenningen bestaat de behoefte om de effecten van veranderingen in ruimtelijke rangschikking van grondgebruik, milieubelasting en beheer op ecosystemen geontergreerd te kunnen bepalen. Hiertoe is het LEDESS-concept voor de standplaats- en vegetatiemodule uitgewerkt met behulp van landsdekkende 1 kmr-gridcelbestanden. Het LEDESS-modelconcept integreert kennistabellen en gegevensbestanden in een GIS-omgeving. Aan de orde komen het modelconcept, de samenstelling van defysiotopen- en vegetatiestructuurbestanden en de benodigde kennistabellen. De werking wordt geollustreerd met een scenario voor spontane bosontwikkeling

Analysis of Indoor Rowing Motion using Wearable Inertial Sensors

In this exploratory work the motion of rowers is analyzed while rowing on a rowing machine. This is performed using inertial sensors that measure the orientation at several positions on the body. Using these measurements, this work provides a preliminary analysis of the differences between experienced and novice rowers, or between a good and a bad technique. The analysis shows that the measured postural angles show no clear trend that would set apart experienced and novice rowers or a bad and a good technique. However, there are clear differences in absolute postural angle’s consistency and timing consistency of strokes between novice and experienced rowers. We also applied a machine learning technique to the data to find the similarities between different rowers and an experienced reference rower. The results can be used to compare the quality of the rowing technique with respect to a reference. In this paper, we present our initial results as well as the challenges that need to be further explored
