Bayesian framework for proficiency tests using auxiliary information on laboratories

A recent paper proposes a Bayesian framework to analyse interlaboratory comparison data when auxiliary information regarding the quality of the practice of laboratories can be investigated or when reported uncertainties are modelled to account for the fact that they are estimates of the unknown variances.

Numerical simulation of pipe flows with uncertain parameters

Pipe flows are influenced by a variety of different parameters and determination of their influence on the result of finite element method (FEM) simulations is computationally expensive. Polynomial Chaos provides an excellent tool for such an analysis.

BIPM Workshop on Uncertainty

The Guide to the Expression of Uncertainty in Measurement (GUM) is an international document that presents recommendations in order to unify the understanding and evaluation of measurement uncertainty particularly in metrology. The revision of the twenty-year old GUM, currently under way, motivated a workshop having various objectives.

EMRP NEW04 Workshop

From April 22. - 23. 2015 the EMRP NEW04 organises the

Workshop and training course : Novel mathematical and statistical approaches to uncertainty


which will be held at PTB Berlin.
This event is for metrology specialists in industry, calibration laboratories, universities and measurement institutes and will introduce the results of the European Metrology Research Programme project NEW04: Novel mathematical and statistical approaches to uncertainty evaluation. Many of the current challenges faced by metrologists and measurement specialists do not fit easily within the uncertainties evaluation framework set out in the current version of the Guide to the expression of uncertainty in measurement (GUM). New methods and new approaches are needed in order to address and stimulate innovative measurement technologies, improve policy making and regulation. The NEW04 project has been developing practical solutions to these challenges. Join us in Berlin to learn how to implement the new methods in your own work and to help define the direction of future research in measurement uncertainty evaluation.
