OPTIMIZING POPULATION MEAN ESTIMATION USING REGRESSION AND FACTOR TYPE ESTIMATORS IN THE PRESENCE OF NON-RESPONSE

Optimizing population mean estimation using regression and factor type estimators in the presence of non-response

This paper addresses the problem of estimating the population mean of the study variable, Y, in the presence of non-response.To address this, we incorporated two additional variables, X and Z, as auxiliary variables.We introduced two classes of estimators that combine regression and Refrigerator Drawer factor type estimators, each applied under dis

Influence of the flow coefficient resistance to the fluctuation of total braking force in hydraulic brakes artillery weapon

In this paper, the fluid flow coefficient is considered according to the model Of hydraulic functioning of Seeds the artillery weapon recoil brake during firing process.The relations for coefficient of hydraulic resistance during primary and additional fluid flow are determined on the basis of the form of the flow through bores.The law of change of
