Sentence examples for aleatory variable from inspiring English sources

An approach to incorporate aleatory uncertainty in Dempster Shafer structures is presented by discretizing the aleatory variable distributions into sets of intervals.

For one site, the empirical distribution of critical headways showed two peaks, that characterized two classes of users and a double normal aleatory variable was chosen to fit the empirical distribution.

The optimization algorithm is able to tackle design variables with uncertainty (e.g., nonlinear stiffness coefficients) as well as aleatory variables such as the initial velocity of the main system.

The proposed algorithm is applied to the design of NACA 4-digit airfoils with four deterministic design variables (the airfoil shape parameters and the angle of attack), one aleatory uncertain variable (the Mach number) and one epistemic variable (β, a geometry parameter) to demonstrate robust optimization under mixed uncertainties.

Fig. 6 Performance of various SCPs in reducing ground-motion aleatory variability.

This uncertainty (especially the within-event aleatory variability) is strongly affected by near-surface site conditions.

As in the aleatory variability analysis described above, the "all proxies" model is considered for comparison.

In engineering, sparse or imprecise data often leads to epistemic uncertainty about the distribution parameters of the aleatory input variables.

Problems are addressed where learning about unobservable inputs of a forward model, e.g. reducing the epistemic uncertainty of fixed yet unknown parameters and/or quantifying the aleatory uncertainty of variable inputs, is based on processing response measurements.

Based on the method of separating epistemic and aleatory uncertainties in a variable, the core idea of the research is firstly to establish a novel deterministic transition model for auxiliary variables, distribution parameters, random variables, failure probability, then to propose the improved importance sampling (IS) to solve the transition model.

In this paper, it is assumed independence between the aleatory and epistemic random variables, as illustrated in Fig. 5.
