Erratum

In the paper by Chowdhury and Chakrabarti [1], Figures 8 and 9were inadvertently swapped. The correct Fig. 8 and Fig. 9 are shownbelow. We regret the mistake.

Fig. 8. Example 6: Load profiles after each step of the proposed aperiodic taskalgorithm. (a) Initial task specification. (b) Load profile after greedy sequencing.(c) Load profile after failure recovery. (d) Load profile after slack utilization.
