This article presents an analysis of intra- and inter-observer errors in pelvic measurements commonly used for sex diagnosis, as well as their impact on the results of discriminant function analyses.

In this study, we investigated bias caused by spatial variability and spatial heterogeneity in outdoor air-pollutant concentrations, instrument imprecision, and choice of daily pollutant metric on ...

For years, a core set of satellite measurements has shaped how scientists, policymakers and modelers understand the Arctic’s ...

Measurement error arises when the observed data deviate from true values due to inaccuracies in measurement processes, potentially leading to biased estimates and ...

Particle analysis is a crucial step in the quality control of bulk materials and is performed in laboratories worldwide. The methods used have usually been established for years and are rarely ...

Test instruments such as oscilloscopes and DMMs (digital multimeters) often let you get the measurement results you need with just the press of a button. But the number on a meter's display or the ...

To acquire the particle size distribution of samples in liquid suspension, the NTA technique uses the properties of Brownian motion and light scattering. When a laser beam is passed through the sample ...
