Cosmological probes pose an inverse problem where the measurement result is obtained through observations, and objective to infer values of model parameters that characterize underlying physical system—our universe, from these observations theoretical forward-modeling. The only way accurately forward-model behavior on small scales via expensive numerical simulations, which are further "emulated...

The excavation damaged zone (EDZ) can be defined as a rock zone where the rock properties and conditions have been changed due to the processes related to an excavation. This zone affects the behavior of rock mass surrounding the construction that reduces the stability and safety factor and increase probability of failure of the structure. In this paper, a methodology was examined for computing...

Abstract. In this paper, we suggest principles of a novel simulation method for analyses of functions g (X) of a random vector X, suitable for the cases when the evaluation of g (X) is very expensive. The method is based on Latin Hypercube Sampling strategy. The paper explains how the statistical, sensitivity and reliability analysis of g (X) can be divided into a hierarchical sequence of simul...

Computing solutions to intractable planning problems is particularly problematic within real-time domains. One approach to this challenge includes off-line computation, such as precomputing a plan library. However, because complex domains preclude creating a comprehensive library, a system must choose a subset of all possible plans to include in the library. Strategic selections will reduce the...
