Advanced Engineering Materials, Volume 27, Issue 2, January 2025.Uncertainty quantification (UQ) of aerospace microstructures: state‐of‐the‐art studies on UQ of microstructures in aerospace materials are examined. The forward problem of uncertainty propagation in process–structure and structure–property relationships is investigated. Additionally, the inverse UQ problem, referred to as “design under uncertainty,” is

An Efficient Approach to Reliability-based Topology Optimization for Continua under Material Uncertainty [PDF]
, 2016 This contribution presents a computationally efficient method for reliability-based topology optimization for continuum domains under material properties uncertainty. Material Young’s modulus is assumed to be lognormally distributed and correlated within

Likelihood smoothing using gravitational wave surrogate models [PDF]
, 2014 Likelihood surfaces in the parameter space of gravitational wave signals can contain many secondary maxima, which can prevent search algorithms from finding the global peak and correctly mapping the distribution.

Measuring Aggregate Human Capital [PDF]
In this paper we construct a set of human capital indexes for the states of the United States for each Census year starting in 1940. In order to do so, we propose a new methodology for the construction of index numbers in panel data sets.
