Focus stacking in UAV-based inspection
(2019)
Diplomityö
Diplomityö
In UAV-based inspection the most common problems are motion blur and focusing
issues. These problems are often due to low-light environment, which can be compensated to some extent with shorter exposure times by using ...

(2019)
Diplomityö
Diplomityö
This thesis investigates the performance of Synthetic Aperture Antennas formed by static formations of UAV swarms in terms of several selected parameters. Of equal importance is the methodology employed in the study, which ...
Aerial Access and Backhaul in mmWave Systems
(2019)
Diplomityö
Diplomityö
The use of unmanned aerial vehicle (UAV)-based communication in millimeter-wave (mmWave) frequencies to provide on-demand radio access is a promising approach to improve capacity and coverage in beyond-5G (B5G) systems. ...
