TL;DR: The dependence of the accuracy and precision of calculated NMR structures on the errors of the distance constraints using sequential simulated annealing was tested and found that the accuracy of the family of structures depends mainly on the quality of the data, but is no better than about 1 A even if the errors in distance constraints are smaller than +/- 1 A.

TL;DR: In this paper, an iterative computation program (XESS) is developed to take into account the additional variance and unequal statistical weights, and the significance and detectability of excess variance is illustrated with data from studies of photonuclear reactions and activation analysis.

TL;DR: Although double precision is usually enough, arbitrary precision increases accuracy and the reproducibility of floating-point computations as mentioned in this paper, and arbitrary precision can be used to increase accuracy and reproduceability of floating point computations.

TL;DR: In this paper, an uncertainty analysis performed in conjunction with the calibration of a subsonic venturi for use in a turbine test facility produced some unanticipated results that may have a significant impact in a variety of test situations Precision uncertainty estimates using the preferred propagation techniques in the applicable American National Standards Institute/American Society of Mechanical Engineers standards were an order of magnitude larger than precision uncertainty estimates calculated directly from a sample of results (discharge coefficient) obtained at the same experimental set point.
Abstract: An uncertainty analysis performed in conjunction with the calibration of a subsonic venturi for use in a turbine test facility produced some unanticipated results that may have a significant impact in a variety of test situations Precision uncertainty estimates using the preferred propagation techniques in the applicable American National Standards Institute/American Society of Mechanical Engineers standards were an order of magnitude larger than precision uncertainty estimates calculated directly from a sample of results (discharge coefficient) obtained at the same experimental set point The differences were attributable to the effect of correlated precision errors, which previously have been considered negligible An analysis explaining this phenomenon is presented The article is not meant to document the venturi calibration, but rather to give a real example of results where correlated precision terms are important The significance of the correlated precision terms could apply to many test situations
