One of the most common measurement errors is using the wrong tool for the job. For example, using a tape measure to estimate small mechanical tolerances or relying on a bathroom scale to track precise ...

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 ...

Global positioning system (GPS) technology has increased the accuracy and efficiency in recording animal locations and has provided data used to parameterize movement models. Although numerous studies ...

All analog measurements — voltage, current, temperature, humidity, etc. — include some amount of error. Your job is to minimize those errors enough to give your ...

This paper presents an EM algorithm for semiparametric likelihood analysis of linear, generalized linear, and nonlinear regression models with measurement errors in ...

Process Engineer Richard Kasica of NIST’s Center for Nanoscale Science and Technology holds a wafer of the type typically produced in the plasma-enhanced chemical vapor deposition chamber. A new study ...

When a warehouse manager suspects poor system performance, the first step is typically to check the real data. Unfortunately, more than 50% of the time, system performance is measured incorrectly.
