To overcome these challenges, we first prove that the optimal beamforming structure is the same for both the power minimization problem and the sum rate maximization problem, and then mathematically ...

Mathematics of Operations Research, Vol. 41, No. 2 (May 2016), pp. 442-465 (24 pages) In view of solving nonsmooth and nonconvex problems involving complex constraints (like standard NLP problems), we ...

Moreover, according to the energy maximization strategy, duration of grazing would be independent of size, while according to the time minimization strategy a positive correlation of grazing activity ...

We present a comprehensive framework for the simultaneous hydrogen flow maximization and degradation mitigation using mixed integer programming in proton exchange membrane electrolyzers. Our approach ...
