This paper constructs internationally consistent measures of macroeconomic uncertainty. Our econometric framework extracts uncertainty from revisions in data obtained standardized national accounts. Applying our model to post-WWII real-time data, we estimate for 39 countries. The cross-country dimension allows us study the impact shocks under varying degrees employment protection legislation. e...

Within the framework of uncertainty-based geographic information science, this paper addresses modeling uncertainties in integrating multiple sources of data, modeling uncertainty in overlay analysis, modeling uncertainty in line simplification, uncertainty-based spatial data mining, uncertainty-based spatial queries, theory and methods for controlling the quality of spatial data, modeling unce...

The performance of a multidisciplinary system is inevitably affected by various sources of uncertainties, usually categorized as aleatory (e.g. input variability) or epistemic (e.g. model uncertainty) uncertainty. In the framework of design under uncertainty, all sources of uncertainties should be aggregated to assess the uncertainty of system quantities of interest (QOIs). In a multidisciplina...
