The highest radiation efficiencies and energies are attained in chain lasers pumped by chain reactions. Technical and allocative efficiencies are necessary conditions, and when they occur together they are sufficient for achieving economic efficiency25. Guidelines have the potential to reduce treatment variation, which can lead to two different kinds of managerial efficiencies. The implementation of automated systems also provides the capability to do real-time decision analysis and could thereby improve efficiencies and hasten clinical follow-up. The power and energy efficiencies obtained in the experiment are, respectively, 8.7% and 6.8% with 50 ns pulse width. The efficiencies of these two systems have been compared and the under-reporting evaluated in relation to each other [43] ; no gold standard was available. More surprisingly, the blocking efficiencies are virtually identical with each other and with the unsheared case (table 6). The penalty values were obtained from inspection of house solutions with acceptable and near acceptable circulation efficiencies. Thus, the revised schedule models reflected the tasks able to be completed by each of the resources considering their respective newly forecasted performance efficiencies.
