A High-Accuracy TOA-Based Localization Method Without Time Synchronization in a Three-Dimensional Space

IEEE Transactions on Industrial Informatics, 2019
Time-of-arrival (TOA) is a widely used localization technique in robotic localization systems. However, TOA-based methods require strict time synchronization between the source (target) and sensors (receivers), which significantly influences the ...

Toa revisted

1995
In 1980 verscheen de NPAO-publikatie 'Techniek, organisatie, arbeidsmarkt' van de projectgroep TOA van de Katholieke Universiteit Nijmegen. Het was het samenvattende rapport van een uitvoerige literatuurstudie naar nieuwe theorieen en wetenschappelijke stromingen op het gebied van de inrichting en besturing van arbeidsprocessen.

The Toa Micro Cell Counter

Scandinavian Journal of Haematology, 1969
Although the physico‐electronic principle on which detection of cells is based in the Toa counter differs from that used in the Coulter counter, results of erythrocyte counts made with the two counters show a similar degree of precision. The two counters are about equivalent in terms of reproducibility of leucocyte counts.

Performance Metric on the Best Achievable Accuracy for Hybrid TOA/AOA Target Localization

IEEE Communications Letters, 2018
This letter proposes a general closed-form formula of the Cramer–Rao lower bound (CRLB) for hybrid time-of-arrival/angle-of-arrival (TOA/AOA) target localization.

Task Organizer Assistant System (TOAS)

2009 Second International Conference on Developments in eSystems Engineering, 2009
Statistics indicates that 90% of errors are caused by the system not by employees. In any normal working day we are suffering from the lack of clarity regarding the work we have to do; in addition to the responsibility we have to take when an error is done or the credits we deserve to earn when a good work is accomplished.
