Встановлено основні джерела похибок діодних цифрових термометрів із зміню- ваними вимірювальними струмами. На основі теореми Вінера-Хінчіна визначено поріг чутливості термометрів як середньоквадратичне відхилення результатів вимірювання, зумовлене шумами вимірювального кола.

The basic sources of errors of diode digital thermometer set with variable measuring currents. On the basis of theorem of Winer-Khinchin the thermometer sensitivity level is determined as the dispersion square root mean of the measurement results predefined by noises of measuring scheme.

Wartime requires decisive actions from the management of enterprises, such as: acceleration of managerial decision-making, flexibility of management style, improvement of communication processes, ensuring the safety of employees and their mental health, maintaining their productivity, etc. All this requires the development of new, adaptation of existing personnel management tools under force majeure conditions of operation.

This article presents results related to the direct solution of the polynomial regression parameters based on the analytical solving of regression equations. The analytical solution is based on the normalization of the values of independent quantity with equidistance steps. The proposed solution does not need to directly solve a system of polynomial regression equations. The direct expressions to calculate estimators of regression coefficients, their standard deviations, and also standard and expanded deviation of polynomial functions are given.

A new approach for finding analytical expression conversion function transmitter physical value by analyzing its output using developed special installation through which by special regulations define the basic parameters of the reference conversion function corresponding to the investigated curve.
