Abstract :

The total cross sections for K-shell ionization of targets, Arsenic and Yttrium (i.e., As & Y), have been calculated due to electron impact at the incident electron energy from ionization threshold to 1 GeV by using the theoretical Khare method modified by Y Kumar et al.3. This method is based on plane wave Born approximation. The calculated cross sections have been compared with the available experimental data and other theoretical cross sections. The present calculated cross sections are in excellent agreement with measured by Merlet C. et al. 15 and Hoffmann et al.22 for As. A good agreement is found between the present calculations and measured Luo Z. et al.21, Ishii K. et al.23 for Y

Abstract :

In this paper, we introduce the concept of (H, 1)(E, 1) product transform and obtained two quite new theorems on (H, 1)(E, 1) product transform of Fourier series and its conjugate series. Our result extends several known result on single summability methods.

Abstract :

This paper deals with the analysis of words from the text of an Indian author. The text of book is analysed and a frequency of noun words is formed. A suitable statistical model, Sichel distribution is fitted to the data and the fitting is found adequate. We have obtained maximum likelihood (ML) estimators and thereafter using flat prior posterior distribution is obtained. Using Metropolis algorithm we draw the posterior samples from which inference are drawn. In the discussion a European text is also compared and we have found that there is richness in Indian literature.
