methodical error

Study of methodological and instrumental components of the error on the accuracy of the reconstruction of temperature field on a wall surface

In the paper the reconstruction of temperature distribution based on resistance measurements of linear sensing elements using tomography method are considered. The methodical and instrumental errors of temperature distribution are investigated and analyzed. In particular the first component depends on number of sensors and degree of used approximation of temperature distribution and the second component depends on the level of random and systematic additive and multiplicative components in measurements.

Methodical errors of measurement of the human body tissues electrical parameters

Sources of methodical measurement errors of immitance parameters of biological tissues are described. Modeling measurement errors of RC-parameters of biological tissues equivalent circuits into the frequency range is analyzed. Recommendations on the choice of test signal frequency for measurement of these elements is provided
