A Study on the Class of Chain Ratio–type Estimators

 This paper considers the problem of estimating the population mean Ybar of the study variate Y using information on different parameters such as population mean $(bar{X})$, coefficient of variation $(C_x)$, kurtosis  $beta_{2(x)}$, standard deviation $(S_x)$ of the auxiliary variate x and on the correlation coefficient, $rho$, between the study variate $Y$ and the auxiliary variate $...

The Study of Histopathological Effects of Electric Welding Fumes on Bronchiole and Lung of Rats

Purpose: The aim of the present study was to identify the quantitative and qualitative changes of bronchiole and lung alveoli in Rat after exposure to welding fumes. Materials and Methods: A total number of 60 male Sprague Dawley Rats were divided into two groups: imental (40) and control (20). Rats of each group were subdivided into 2, 4, 6 and 8 subgroups. Experimental Rats were exposed to w...

On Line Monitoring for Defects in Electric Arc Stud Welding

ABSTRACT The application of on-line monitoring system for recording main welding parameters during electric arc stud welding process at different electric arc stability changes is described in this paper. In the first part of the paper, the basics of electric arc stud welding process, and equipment for stud welding and process monitoring used in experimental part is described. In the second par...
