Experimental benchmarking of next-gen indoor positioning technologies (unmodulated) visible light positioning and ultra-wideband Ghent University
Experimental Benchmarking of Next-Gen Indoor Positioning Technologies (Unmodulated) Visible Light Positioning and Ultra-Wideband Interuniversity Microelectronics Centre Ghent University
Within the context of the Internet of Things (IoT), many applications require high-quality positioning services. As opposed to traditional technologies, the two most recent positioning solutions: 1) ultra-wideband (UWB) and 2) (unmodulated) visible light positioning [(u)VLP] are well suited to economically supply centimeter-to-decimeter level accuracy. This manuscript benchmarks the 2-D positioning performance of an 8-anchor asymmetric ...
Positioning at the Olympic Winter Games: examining the targeting of Olympic winter sports by medal-winning nations Vrije Universiteit Brussel
Purpose: Since the 1990s, the International Olympic Committee has offered nations more medal-winning opportunities at every Winter Games. Meanwhile, many countries are constrained by their limited financial resources to target sports strategically. The purpose of this paper is to examine the targeting approaches to Olympic Winter Sports of National Sports Agencies (NSAs), and to identify the factors they assess in the decision-making process. ...
An experimental analysis of the effect of reflections on the performance of visible light positioning systems in warehouses Ghent University
In this paper, an experimental evaluation of the effect of multipath reflections on two 3D positioning algorithms is experimentally compared. The VLP algorithms use the received signal strength (RSS) for estimating the receiver`s 3D position without prior knowledge of its height. An experimental overall median accuracy of 10.5 cm was achieved in a 4 x 4 x 4.1 m3 test area. The effect of multipath reflections was recreated using a storage shelf ...
Off-line evaluation of indoor positioning systems in different scenarios: the experiences from IPIN 2020 competition Ghent University
Experimental assessment of the accuracy of modulated and unmodulated visible light positioning Ghent University
Experimental performance evaluation of outdoor TDoA and RSS positioning in a public LoRa network Ghent University
This paper experimentally compares the positioning accuracy of TDoA-based and RSS-based localization in a public outdoor LoRa network in the Netherlands. The performance of different Received Signal Strength (RSS)-based approaches (proximity, centroid, map matching,...) is compared with Time-Difference-of-Arrival (TDoA) performance. The number of RSS and TDoA location updates and the positioning accuracy per spreading factor (SF) is assessed, ...
Teacher educators' professionalism in practice: Positioning theory and personal interpretative framework KU Leuven
This study connects to the international call for research on teacher educator professionalism. Combining positioning theory with the personal interpretative framework, we examined the relationship between teacher educators' positioning and their teacher education practices. The interpretative analysis of qualitative data from twelve experienced Flemish teacher educators revealed three teacher educator positionings: a teacher educator of ...
