Because of the enhanced TIR mechanism, a more reflective and narrower bandwidth polymeric linear variable filter can be realized by optimizing the writing beam intensity.
By optimizing the assisting ion beam current, IBAD-MgO thin films had pure (002) orientation, excellent biaxial texture and very smooth surface with a root mean square surface roughness of less than 1 nm.
In this section, the problem of interest is to maximize the system throughput by optimizing the precoding and power allocation subject to individual power constraints P k = [p1, p2,... p K ] on beam k.
It maximizes the throughput of the macrocell by optimizing the trade-off between multiplexing gain and multiuser interference, and it also suppresses the cross-tier interference with a reduced number of beams.
By optimizing the focus of the wavefront sensing beacon, the spot quality can be improved significantly. Figure 3(c) shows that for the same entry beam diameter (2 mm), by changing the beacon focus by ~-10 diopters so that the outer retina is in focus, a relatively symmetric single spot pattern can be obtained.
In beam-based additive manufacturing, although a great deal of effort has been made to minimize the residual stresses, it is still elusive how to do so by simply optimizing the manufacturing parameters, such as beam size, beam power, and scan speed.
Our objective is to maximize the average sum rate while keeping fairness between the users by optimizing both the cluster and beam allocation[3, 22], A n = [ A 1 n, A 2 n, …, A Q n ].
Continuous gantry motion, dose-rate variation and MLC motion were approximated by optimizing individual beams at 2° gantry angle increments.
The beam angles of IMRT were initially optimized by the beam angle optimization algorithm (Varian Eclipse 10.0); a set of initial optimization objectives were loaded into the treatment planning system.
The beam angles of Hybrid-IMRT were initially optimized by the beam angle optimization (BAO) algorithm (Varian Eclipse 10.0).
