THE USE OF CORRELATION ANALYSIS IN ASSESSING THE UNCERTAINTY OF THE INFLUENCE OF EXTERNAL FACTORS ON THE RESULT OF THERMAL CONTROL OF BIOLOGICAL OBJECTS
Main Article Content
Research task. The paper considers the solution of the scientific and practical problem of determining the influence of external factors on the result of non-contact thermal control of biological objects. Object of study. A human was chosen as a biological object. Research progress. Establishing the correlation dependence was carried out in the two most opposite seasons in terms of climate parameters – winter and summer. One person was taken for the study, whose temperature was measured using a FLIR Vue Pro R 640 thermal imager mounted on a Cheerson CX-20 quadcopter at one-hour intervals throughout the day. The data were obtained in the summer period on August 10, 2022. In the winter period, measurements were carried out on January 20, 2022. Research results. Conclusions were made about the absence of a linear correlation between humidity, air temperature and body temperature of BO in the summer period. On the contrary, a high correlation was established between all the indicated parameters in the winter period. Conclusions were made about the need to develop a mathematical model of the factor influence on the thermal control result of the BO in order to obtain analytical ratios for evaluating the quantitative information on each of the temperature control indicators under the factor influence on the conversion function of these indicators. It is noted that such a model will make it possible to rank the indicators of temperature control according to the decrease in their sensitivity to changes in the levels of the temperature control parameter. Usage suggestions. It is proposed to calculate the correcting coefficients to determine the exact value of the body temperature, because it was experimentally established that the values of the body temperature in the winter period differ from the actual values precisely due to the influence of the temperature of the external environment.
