Distributed multi-agent magnetic field norm SLAM with Gaussian processes

Accurately estimating the positions of multi-agent systems in indoor environments is challenging due to the lack of Global Navigation Satelite System (GNSS) signals. Noisy measurements of position and orientation can cause the integrated position estimate to drift without bound. Previous research has proposed using magnetic field simultaneous...

Mapping the magnetic field using a magnetometer array with noisy input Gaussian process regression

Ferromagnetic materials in indoor environments give rise to disturbances in the ambient magnetic field. Maps of these magnetic disturbances can be used for indoor localisation. A Gaussian process can be used to learn the spatially varying magnitude of the magnetic field using magnetometer measurements and information about the position of the...

Large-scale magnetic field maps using structured kernel interpolation for Gaussian process regression

We present a mapping algorithm to compute large-scale magnetic field maps in indoor environments with approximate Gaussian process (GP) regression. Mapping the spatial variations in the ambient magnetic field can be used for 10-calization algorithms in indoor areas. To compute such a map, GP regression is a suitable tool because it provides...

Three Symmetries for Data-Driven Pedestrian Inertial Navigation

The last years have seen a growing body of literature on data-driven pedestrian inertial navigation. However, despite this, it is still unclear how to efficiently combine classical models and other a priori information with existing machine learning frameworks. In this paper, we first categorize existing approaches to data-driven pedestrian...

Groyne field nourishments: A research into the application of feeder nourishments to supply sediment to the main channel

In the Waal bed degradation occurs, which is mainly induced by a large number of river regulations measures done in the past. Rijkswaterstaat develops possible measures and new techniques to stop riverbed erosion and/or mitigate the negative effects. One of the possible new techniques to reduce riverbed erosion locally is groyne field...

Public Procurement For Innovation: Optimising the preparation phase of the innovation partnership and competitive dialogue procedure for Dutch public authorities procuring for innovation in the Physical domain

The possibilities public procurement offers regarding the stimulation of innovation for the benefit of economic growth and the competitiveness of markets have been increasingly receiving attention over the past two decades. In 2014 a long awaited update of the European directive governing procurement procedures was published. Among these...

JAY: Kitting as optimization tool of aircraft maintenance

Kitting as (LEAN) method in handling and supplying material and tools is not used in the aircraft maintenance process of KLM. That was one of the researchers first findings when starting this study for KLM Royal Dutch airlines. Kitting is the gathering of components and parts needed for the manufacture of a particular assembly or product....
