The subsequent investigation found two main causes. The first was a misunderstanding between Air Traffic Control (ATC) and the flight crew of the aircraft that was taking off. The second was a lack of coordination between the flight crew members to ensure that the runway was cleared for takeoff...
The RSSI of the current active link is still within the allowed range, but the link rate has fallen below the minimum rate threshold or stayed in this low-speed state longer than the minimum rate holding time. When performing an emergency handover, the vehicle-mounted AP chooses the candidate...
Global warming has altered air and ocean currents. This changed global precipitation and temperature patterns. Thus, groundwater depletion increases with global warming78. A shift in intense rainfall events may increase flooding hazards in terrain unfavorable for groundwater recharging78. Researchers tried...

(Gonçalves et al.2017). The major benefit of implicit modeling relies on its speed, which allows faster assessments of new information and uncertainty simulations, accordingly reducing the intrinsic risks of geological modeling (Cowan et al.2003; Wellmann et al.2010; Birch2014; Vollgger et al...
Wind speed and air temperature were collected from either Kahului (WBAN 22516) or Kapalua (WBAN 22552) airport weather stations. For the mass-balance models we used an atmospheric radon activity of 30 dpm/m3 (Kelly, 2012), 226Ra supported 222Rn activity of 79 dpm/m3 (as measured by ...
Autonomous Landing of a Multirotor Micro Air Vehicle on a High Velocity Ground Vehicle In this paper we address these issues by solving the problem of the automated landing of a quadcopter on a ground vehicle moving at relatively high speed. We present our system architecture, including the struc...
(Abramowski2007). In the latter case, a Venturi nozzle is generated between the foil and the ground, so the negative lift is due to the Bernoulli effect. This effect is used by race cars and is caused by the Venturi nozzle between airfoil and ground, where high-speed low-pressure air ...
