The intertrial reliability for serve velocity ranges between 3·2% and 3·5%.
94 Moreover, previous research showed significant correlations between ball toss and strength (ie, isokinetic trunk rotation; individual values of velocity at 30% of 1RM bench press), 95 96 as well as serve velocity, 97 suggesting that these tests are fundamental indicators of whole body explosive power regardless of throwing technique.
98 In this regard, the tennis serve velocity test appears to show high external validity in terms of its relationship with tennis functional performance, as it is a basic action relying on multiple body segments to produce power through properly timed rotations and complex coordinated muscular activations.
98 100 101 Serve velocity is measured with a radar gun positioned behind the server.
At 6 feet 9 inches, Isner can serve with velocity, accuracy and tremendous angle.
The subscripts,, and are the handover preparation information corresponding to the load difference between the target and serving cells, the velocity of UE, and the service type, respectively.
The dominant factors of the cost function are the load different between the target and serving cells, the velocity of UE, and the service type.
Based on a priori magnetic map, the system is capable of computing the vehicle range and velocity, serving critical inputs for realizing effective AUV short range homing and docking.
Since the load-based scheme, velocity-based scheme, and service-based scheme considered only a single factor for each scheme, the load difference between the target and serving cells, the velocity of UE, and the service type, respectively, they showed better HFR performance than the fixed hysteresis but worse than the proposed cost-based adaptive hysteresis scheme.
Thus, to reflect the performance difference with the different weight value for the three factors such as the load difference between the target and serving cells, the velocity of the UEs, and the service type, we used the cost-based adaptive hysteresis scheme with the weight of ( = 0.1, = 0.4, = 0.5) confirming the sum of weights was equal to 1.
