(At United Airlines, by contrast, turnaround time is closer to thirty-five minutes, and requires a ground crew of twelve and three agents at the gate).
At Southwest, the time it takes to get a plane that has just landed ready for takeoff — a key index of productivity — is, on average, twenty minutes, and requires a ground crew of four, and two people at the gate.
The method has advantages in that it does not require a ground plane assumption.
While external validation requires a ground truth which is not provided in most applications, particularly in the streaming case, internal clustering validation is efficient and realistic.
Controlling multiple UAVs concurrently not only requires a ground station that controls the UAVs, but also a motion-capture data server that obtains the indoor locations of the UAVs.
Whether it is high-dimensional stream clustering [14, 24], hierarchical stream clustering [15, 23] or sensor data clustering [19, 20, 21], evaluating the clustering output using external evaluation measures (like SubCMM [17, 18]) requires a ground truth that is very difficult to obtain in the above-mentioned scenarios.
So will Decisive Storm persevere militarily until the Houthi coup -- supported by former Yemeni President Ali Abdullah Saleh, his son Ahmed, and the Iranian Revolutionary Guard -- is undone, even if this requires a ground operation and not just air and naval operations?
However, the development and testing of prostate cancer CAD solutions requires a ground truth map of the cancer to enable the generation of receiver operator characteristic (ROC) curves.
Plugs installed in but not limited to basements, garages, outdoors, or indoors and accessible from grade, bathrooms, etc. will require a Ground Fault circuit breaker or plug, UNLESS it is dedicated to a "fixed" appliance such as a washer, refrigerator, etc. Arc Fault and Ground Fault circuits are not compatible with fluorescent light fixtures!
Those generally require a ground-based cellphone connection.
