Every year, for ten years now, the IPIN competition has aimed at evaluating real-world indoor localisation systems by testing them in a realistic environment, with movement, using EvAAL framework. The provided unique overview of state-of-the-art systems, technologies, and methods positioning navigation purposes. Through fair comparison performance achieved each system, was able to identify most promising approaches pinpoint critical working conditions. In 2020, included 5 diverse off-site...
Human-robot collaboration and cooperation are critical for Autonomous Mobile Robots (AMRs) in order to use them indoor environments, such as offices, hospitals, libraries, schools, factories, warehouses. Since a long transition period might be required fully automate facilities, we have deploy AMRs while improving safety the mixed environments of human mobile robots. In addition, behaviors difficult predict. this paper, present Digital Twin system named DigiMobot support, manage, monitor,...
We investigate the electronic structure of $2H\text{\ensuremath{-}}\mathrm{Nb}{\mathrm{S}}_{2}$ and $h$-BN by angle-resolved photoemission spectroscopy (ARPES) intensity calculations. Although in bulk form, these materials are expected to exhibit band degeneracy ${k}_{z}=\ensuremath{\pi}/c$ plane due screw rotation time-reversal symmetries, we observe gapped dispersion near surface. extract from first-principles calculations near-surface probed ARPES find that calculated spectra region...
Abstract Moiré superlattices consisting of two-dimensional materials have attracted immense attention because emergent phenomena such as flat band-induced Mott insulating states and unconventional superconductivity. However, the effects spin-orbit coupling on these not yet been fully explored. Here, we show that single- double-bilayer antimony honeycomb lattices, referred to antimonene, form moiré a Bi(111) substrate due lattice mismatch. Scanning tunnelling microscopy (STM) measurements...
Moir\'e superlattices consisting of two-dimensional (2D) materials have attracted immense attention because emergent phenomena such as flat band-induced Mott insulating states and unconventional superconductivity.

We use pump-probe, spin- and angle-resolved photoemission spectroscopy (ARPES) with a 10.7 eV laser accessible up to the Brillouin zone edge, reveal entire band structure around Fermi level, including unoccupied side, for elemental bismuth (Bi) spin-polarized surface states. Our data identify Bi as in strong topological insulator phase (${Z}_{2}=1)$ against prediction of most calculations. unveil that states possess saddle points yielding van Hove singularity. The unique feature provides an...
Although activity recognition has been studied considerably for the last two decades, it is still not so easy to handle complicated classes in a specific domain. The 2nd Nurse Care Activity Recognition Challenge Using Lab and Field Data aims explore part of those activities by focusing on nurse caring. Our team, "UCLab", found that main problem challenge imbalance unevenness dataset, each which often happens real-field data. Considering problem, we approached using Random Forest-based method...
We use a pump-probe, spin-, and angle-resolved photoemission spectroscopy (ARPES) with 10.7 eV laser accessible up to the Brillouin zone edge, reveal for first time entire band structure, including unoccupied side, elemental bismuth (Bi) spin-polarized surface states. Our data identify Bi as in strong topological insulator phase ($Z_2$=1) against prediction of most calculations. unveil that states possess saddle points yielding van Hove singularity, providing an excellent platform future...
We investigate the electronic structure of $2H$-$\mathrm{Nb}\mathrm{S}_2$ and $h$-$\mathrm{BN}$ by angle-resolved photoemission spectroscopy (ARPES) intensity calculations. Although in bulk form, these materials are expected to exhibit band degeneracy $k_z=\pi/c$ plane due screw rotation time-reversal symmetries, we observe gapped dispersion near surface. extract from first-principles calculations near-surface probed ARPES find that calculated spectra region reproduce spectra.
