This paper proposes a novel heuristic algorithm for maximum loss-of-load probability (LOLP) constrained unit commitment (UC) of significant wind power integrated system. Wind generation fluctuation and generator stochastic outage are considered in the model, and the maximum LOLP constrained UC is to prepare appropriate spinning reserve (SR) to keep the probability of loss of load under a predetermined...
Proposed here is a novel architecture for a fault-tolerant real-time system. We employ a checkpoint rollback strategy with double modular redundancy. Main consideration is given to how to recover from both transient and permanent faults without any built-in fault-detection modules or spare processors. Besides state comparison between duplicated tasks, the system has access to the state of the previous...
An optimal checkpoint strategy for fault-tolerance in real-time systems is addressed in this paper. We consider multiple real-time tasks with arbitrary periods that are scheduled by Rate Monotonic (RM) algorithm. Equidistant checkpointing is maintained for each kind of task, while the width of checkpoint intervals is different with respect to the task. We propose a method to determine the optimal...
Mathematical models dealing with childhood viral infections consider the spread of disease according to the law of mass action. This law states that there are random encounters (or contacts) among susceptible and infectious individuals. Therefore, mathematical descriptions of the transmission of infections are heavily dependent on the assumptions concerning the contact rate. In order to develop...
