The uncertainty tree: Reducing the uncertainty of uncertainty analysis

Review of Scientific Instruments, 2002
Uncertainty analysis is an integral aspect of experimental measurements, though accurately assessing the flow of uncertainty in a measurement system—particularly for complicated systems with more than a few variables—can become a challenging, error-prone task, while being less enjoyable than it should be.

Uncertainty analysis of reflectance colorimetry

SPIE Proceedings, 2003
AbstractThe uncertainty associated with the quantitative description of the color of an object is often necessary for determining the acceptability of that object for its intended application. Uncertainties are also required for establishing the traceability of a measurement to a national metrology institute.

ATARR Uncertainty Analysis.

1991
Abstract : The Wright-Patterson Air Force Base Advanced Turbine Aerothermal Research Rig (ATARR) is a short-duration, turbine stage testing facility. The ATARR facility is designed for a nominal 2-second run time. This long run time created the requirement for fast-acting shut-off valves to avoid over-heating the eddy brake system and other potential ...

Alignment Uncertainty and Genomic Analysis

Science, 2008
The statistical methods applied to the analysis of genomic data do not account for uncertainty in the sequence alignment. Indeed, the alignment is treated as an observation, and all of the subsequent inferences depend on the alignment being correct. This may not have been too problematic for many phylogenetic studies, in which the gene is carefully ...

Uncertainty Analysis in River Modelling

2015
Uncertainty analysis is an essential step in river modelling. Knowledge of the uncertainty is crucial for a meaningful interpretation of the model results. In this chapter we describe the whole process of an uncertainty analysis in four steps: identification, prioritization, quantification and propagation.

Spectral analysis for uncertainty quantification

Numerical Linear Algebra with Applications, 2020
AbstractDuring the past few decades, uncertainty quantification (UQ) techniques have been developed and applied to many applications. The majority of these techniques have been applied directly to specifically defined problems, that is, problems described by a mathematical operator and a specific source term, both which may be endowed with uncertainty.

Decision analysis and clinical uncertainty

Current Opinion in Pediatrics, 2003
Decision analysis is a tool to aid decision-making in the face of uncertainty. Typically, clinical decision-making involves the selection of one or more therapeutic alternatives when the outcome of that decision cannot fully be known at the time the decision must be made.

COST UNCERTAINTY ANALYSIS

1968
Abstract : An important aspect of cost research is the measurement of the uncertainty inherent in the projection of system cost. Only recently have approaches utilizing such tools as statistical decision theory and probability theory been formulated. The study described here explores and evaluates three such techniques: (a) The derivation of moments ...
