This paper considers linear regression models when neither the response variable nor the covariates can be directly observed, but are measured with multiplicative distortion measurement errors. To ...

Calibration techniques form the cornerstone of quantitative analytical chemistry, ensuring that measurements are both accurate and reliable across diverse sample matrices. Recent advances have ...

Calibration of a universal testing machine involves validation of the accuracy of the system’s instruments responsible for achieving displacement and force measurements. Technically speaking, ...

Accurate, reliable, and repeatable operation of monitoring and control loops in industrial automation and control systems (IACSs) is vital to maintaining the safety and reliability of a production ...

Oxygen deficiencies, explosive atmospheres, and exposure to toxic gases and vapors injure or kill hundreds of workers every year during confined space entry procedures. The atmospheric conditions that ...

• Force vectors don’t want to remain in line with the object being pushed. • Load-cell specifications usually do not call out accuracy, but rather linearity, repeatability, and hysteresis. • Accuracy ...

ISA recently published the third edition of Calibration Handbook of Measuring Instruments by Alessandro Brunelli. In this Q&A feature, Brunelli highlights the focus, importance, and differentiating ...

"We calibrate once a year whether we need it or not." "We were told to calibrate every 180 days." "Calibration? We send it out to have that done every quarter." "Bump test? Yeah, my buddy Jim holds ...

Fully conformant ISO 17025 calibration services for complex electronic test equipment are now available worldwide from Agilent Technologies. The ISO 17025 standard governs both calibration laboratory ...
