The primary collision pattern is beneficial for the bulk motion of tumbling of the particle clusters, whereas the secondary pattern suppresses it.
This kind of turn is… known to be one of the primary causes of collisions between cars and people who bike resulting in serious injury or fatality.
Number of primary collisions (direct collisions of the robot with an obstacle, i.e., running into obstacles), Number of secondary collisions (collision only some parts of the robot such as the sensor cables, etc)., Number of deadlocks, Duration of the experiment, Trajectory of the robot's movement.
If the secondary user transmits with a power calculated from (2) when the true state of the primary user is active, a collision occurs and all the packets involved in the collision are lost.
To see this, we need to compare the probability of collision of the primary user's packets for these schemes.
This scheduling algorithm aims to minimize the probability of packet loss of the secondary user under an average power constraint at the secondary user and a maximum probability of collision of the primary user packets.
Hence, we believe that the microwave radiation intensified the effective collision rates of the primary particles.
In cognitive radio network, though the secondary user can be allowed to utilize the idle spectrum unoccupied by primary users, the collision probability of the primary users should be less than a threshold [18].
In 2007, Gerry Beck, one of the primary restorers, was in a fatal collision of his P-51A and a P-51D during AirVenture 2007.
The authors study the optimal opportunistic spectrum access problem and formulate it as an optimization problem that the secondary user maximizes spectrum hole utilization under the constraint of collision tolerable level of the primary users.
