.... 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...

... to gather a single concentration measurement. Our goal is to place this single sensor in Ω to maximize the expected information gained about the amplitude of the source. We discretize Ω using 2000 uniform random points, which produces a design space with 2000 possible experimental designs. For this problem...
