### Measurement Theory

Data is displayed for academic year: 2023./2024.

#### Course Description

Data Measurement. Fields: monitoring, research, development, measurement, control. DMS (Data Measurement System): definition, structure, outer and inner limits, classification according to the information and energy.Experiment. Fundamentals and terms (requirements, limits, repeatability). Carrying out of an experiment and records. Error analysis. Direct measurements and weighted factors. Quantities measured indirectly. Weighted regression functions, uncertainty of parameters. Application of matrix in the error analysis. Uncertainty of the predicted value. Conditional measurements and conditional equations. Calculation of corrections. Examples. Mathematical model of measurand. Parameters of real measurements (final resolution, hysteresis, arithmetic of final precision, non-corrected values). Correlated and non-correlated quantities. Effective level of freedom and level of confidence. Examples.Results of measurement. Rejection of result according to Chauvenet criterion.
