Error analysis for sampling of slurries: volumetric errors

Journal of Analytical Atomic Spectrometry, 1989
The propagation of errors associated with the sampling of heterogeneous solutions consisting of small particles in a liquid media (e.g., slurries) is considered. Errors associated with uncertainties in the sample volume, the number of particles extracted in the sampling volume and the variation in the mass of the individual particles are considered in ...

Sources of conductance volumetric measurement errors

Proceedings of the Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 1992
The purpose of this work was to theoretically analyze the principles of conductance volumetric measurements, and to provide explanations and predictions of error sources. Cardiac volume measurements, based on conductance volumetric techniques have produced inconsistent and conflicting results.

Errors in volumetric respirometry: Description of an improved microrespirometer

Analytical Biochemistry, 1971
Abstract 1. 1. When the capabilities for simplicity of construction and operation of the capillary volumeter are carried to extremes, certain random and constant errors appear which render the instrument unstable and insensitive. Some implications of these errors for respiration data in the literature are discussed. 2. 2.

An Analysis of the Volumetric Error Uncertainty of a Three-Axis Machine Tool by Beta Distribution

International Journal of Machine Tools and Manufacture, 2000
This paper addresses the stochastic nature of the volumetric error of a machine tool in 3-dimensional workspace, and proposes a new model helping the prediction of the tolerances of products caused by uncertainties of a machine tool without going through

Volumetric Error Control in Layered Manufacturing

Volume 4: 19th Design for Manufacturing and the Life Cycle Conference; 8th International Conference on Micro- and Nanosystems, 2014
This paper presents a novel method for adaptive slicing based on volumetric error considerations for Layered Manufacturing (LM). In the general LM process uses constant layer thickness throughout the part height which leads to poor surface finish at inclined surfaces.

Sensitivity of volumetric brain analysis to systematic and random errors

2010 IEEE 23rd International Symposium on Computer-Based Medical Systems (CBMS), 2010
Brain structures are subjected to changes caused by genetic, environmental factors or disease and gender, age related reasons. Different methods have been developed to capture these changes, but their agreement over the same data may significantly vary. These variations are attributed to the methodological differences of the employed methods.

Volumetric error compensation for multi-axis machines

[Proceedings] 1992 IEEE International Conference on Systems, Man, and Cybernetics, 2003
A general error prediction and compensation scheme which implicitly includes the non-rigid body condition is developed for an arbitrary multi-axis machine. The accuracy and precision of tasks performed by multi-axis machines are profoundly affected by their volumetric accuracy. The volumetric accuracy of a machine depends on numerous factors, including
