NAVIGATION SYSTEM FOR LHD MACHINES
IFAC Proceedings Volumes, 1995 Load, haul and dump (LHD) machines are used in mines to carry ore from loading point to dumping point. This paper presents techniques developed to automatize the work of LHD machines. The work concentrates on navigation of the .machines using dead reckoning, artificial beacons and distance measurement from vehicle to tunnel walls.

ViNav: A Vision-Based Indoor Navigation System for Smartphones
IEEE Transactions on Mobile Computing, 2019 Smartphone-based indoor navigation services are desperately needed in indoor environments. However, the adoption of them has been relatively slow, due to the lack of fine-grained and up-to-date indoor maps, or the potentially high deployment and ...

FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Detection of variance changes and mean value jumps in measurement noise for multipath mitigation in urban navigation [PDF]
, 2008 This paper studies an urban navigation filter for land vehicles. Typical urban-canyon phenomena as multipath and GPS outages seriously degrade positioning performance.

Robust TDOA/FDOA estimation from emitter signals for hybrid localization using UAVs
Defence Technology, 2022 This paper considers the time difference of arrival (TDOA) and frequency difference of arrival (FDOA) estimation problem for joint localization using unmanned aerial vehicles (UAVs), involving range migration (RM) and Doppler ambiguity within observation
