The worst case measured was when traction power was cut off at a relatively low speed while accelerating, in order to meet a speed restriction.
By characterizing the worst-case measure for a related stochastic minimax game, it is shown that the worst-case uncertain system can be represented in the form of a parametric perturbation of the nominal system.
In the present non-dominated framework, however, it appears questionable but indeed rather unlikely that such a worst-case measure (bar {P}) exists in (mathcal {R}) for general claims.
Analogously the lower good-deal bound (pi ^{l}_{cdot }left (Xright)) and corresponding hedging strategy can also be computed, but under the worst-case measure (P^{underline {a}}in mathcal {P}_{[underline {a},overline {a}]}) for "minimal" volatility matrix (underline {a}).
In the simpler framework of drift uncertainty only, there exists a worst-case measure (bar {P}in mathcal {R}) such that (pi ^{u}_{cdot }(cdot)=pi ^{u,bar {P}}_{cdot }(cdot)) holds and the good-deal hedging strategy (bar {phi }^{bar {P}}) in the model (bar {P}) is robust w.r.t.
Our controller validation criterion computes an upper bound for the worst case performance, measured in terms of the H∞-norm of a weighted closed loop transfer matrix, achieved by a given controller over all plants in such uncertainty sets.
In the presented simulation results, after ms a quality decrease of dB in average and dB in the worst case is measured, whereas the available user bitrate is reduced by more than % because of the combined effects of allocated bandwidth decrease and BLER increase.
At times the CEOs were called in to deal with resistance to the programme, whereby they would either discuss the situation with the resisters, attempt to instill a sense of purpose, or in the worst case, threaten disciplinary measures for not adhering to SPI practices.
This task is very time expensive so that the major drawback highlighted by the authors is the extremely high latency which, in the worst case, has been measured in about 10 s.
Worst case scenario, more strict measures and punishment for daring to ask for changes.
