We extend the traditional two-machine flow shop by dividing the operations into two categories: supporting tasks and regular jobs.
It has become very essential to manage the restriction due to the boundaries which divide the engine operation conditions into the normal and the abnormal ones such as knocking and misfiring because an optimal operation condition is often close to such a boundary.
Given this situation, the current study sought to divide the mapping operation into two steps.
They divide the protocol operation into two phases: setup phase and steady state phase.
The simulation of vehicle dynamics is based on the essential train dynamics equations in Hay [25], which divide the train operation between each pair of neighboring stations into acceleration, cruising, and braking stages, and then calculates train energy consumption and travel time along a given track alignment with an iterative process [21].
As mentioned in the introduction of this paper, much research work on FD-MIMO systems is currently devoted to reducing system complexity through so-called hybrid architectures, which divide the precoding operation into an analog RF domain part and a digital base band processing part.
Thus, we can divide the pump operation into three main steps, as is shown in Fig. 5. Initially (A), despite the general trend to move backwards due to the positive trends of the backward rates rr1 and rr6, once r3 is taken, the system might complete easily the cycle in the forward direction, because the forward rates r3, r4, r5 and r6 have a positive trend in the most of the time.
Due to the high power consumption of the digital scheme [15, 16] and the possible performance loss of the analog scheme, the hybrid beamforming scheme has been presented in [17, 18] to divide the beamforming operations between the analog and digital domains, where the required number of RF chains is reduced.
The authors divided the matching operation over multiple threads.
