Tracking for Half an Hour [article]

Ran Tao, Efstratios Gavves, Arnold W.M. Smeulders
2017 arXiv   pre-print
On 10 new half-an-hour videos with city bicycling, sport games etc, the proposed tracker outperforms others by a large margin where the 2010 TLD tracker comes second.  ...  This illustrates the difference between optimization for short-term versus long-term tracking.  ...  Therefore, for "blind-upd", the model gets drifted on half-an-hour videos.  ...

Theoretical efficiency of a gear based azimuthal tracked photovoltaic platform

B. Butuc, G. Moldovean, N. Creanga
2011 The Renewable Energies and Power Quality Journal (RE&PQJ)  
The paper presents the results of a theoretical analysis developed to estimate the energy produced by an azimuthal tracked photovoltaic (PV) system.  ...  The analysis is made in the hypothesis of clear sky for Braşov -Romania geographical coordinates: 45.65°N latitude, 25.58°E longitude.  ...  The tracking efficiencies were comparatively analysed considering that the PV surface position is modified at every half an hour and an hour time intervals.  ...
