For GALILEO-based train-borne positioning systems, the digital map is a very essential and important element since it enables relating the measured sensor data to the geometry and topology of the track. This contribution points out the relevance of the digital map within a map-matching process, which is necessary for all GALILEO-based train positioning systems. It also focuses on the generation of...
Compared to WCDMA, the LTE radio access has a significantly shorter Transmission Time Interval (TTI) in order to reduce end-to-end delays. However, if a User Equipment (UE) at the cell edge is limited by its available transmission power, it may not be able to transmit an entire VoIP packet during one TTI, since the instantaneous source data rate is too high. Thus TTI bundling has been recently introduced...
Methods that faithfully and robustly capture the geometry of complex material interfaces in labeled volume data are important for generating realistic and accurate visualizations and simulations of real-world objects. The generation of such multimaterial models from measured data poses two unique challenges: first, the surfaces must be well-sampled with regular, efficient tessellations that are consistent...
