.... In addition, the paper shows that the probability of simultaneous presence of critical events is practically insensitive to the distribution of the events durations. These counter-intuitive results provide the powerful opportunity to evaluate the risk of overlapping of random events through the mean duration...

... Random Uncertainty During the past 30 years, the Bayesian network (BN) has become a key method for representation and reasoning under uncertainty in the fields of engineering [ 1 , 2 ], machine learning [ 3 , 4 ], artificial intelligence [ 5 , 6 ], etc. In a BN, random variables are denoted...

To address this issue, this paper proposes an improved EKF that is resilient against sensor failures. This work focuses on the resilient EKF’s...

...Anthony M. Ferrar This paper presents the ways that sample rate, sample time, and number of test replications can affect the random uncertainty in a measurement. Typical steady timewise experiments seek the average values of measured variables. Even in this case, sample rate and sample time can...
