High-accuracy localization systems for non-line-of-sight (NLOS) environments have been a popular focus of research on indoor positioning. In particular, the use ultra-wideband (UWB) technology ranging is emerging as an effective method due to its high accuracy. To improve overall performance UWB systems, combining with inertial navigation system (INS) commonly used positioning approach. However, measurements are affected by outliers under NLOS propagation radio signals. addition, INS tend...
Reliable absolute positioning is indispensable in long-term systems. Although simultaneous localization and mapping based on light detection ranging (LiDAR-SLAM) effective global navigation satellite system (GNSS)-denied environments, it can provide only local results, with error divergence over distance. Ultrawideband (UWB) technology an alternative; however, non-line-of-sight (NLOS) propagation complex indoor environments severely affects the precision of UWB positioning, LiDAR-SLAM...
The flow produced in an enclosed cylinder of height-to-radius ratio two by the counter-rotation top and bottom disks is numerically investigated. When Reynolds number based on radius disk rotation increased, axisymmetric basic state loses stability different complex flows appear successively: steady states with azimuthal wavenumber 1; travelling waves; near-heteroclinic cycles; 2. This scenario understood a dynamical system context as being due to nearly codimension-two bifurcation presence...
