Nowadays most Printers demand PostScript files with scalable fonts instead of bitmapped fonts, as the later are not adequate for most cases. In addition, PDF files generated from PostScript files with embedded bitmapped fonts are poorly rendered on a computer screen. On the other hand, traditionally, PostScript files generated from TEX sources contained bitmapped fonts just because METAFONT gen...

The present study tries to investigate the effect of font size on recognition of the key textual words, to determine if the students can find the answers to some multiple choice and true/false questions easier in a text typed with a larger or smaller font size. Forty male and female students were selected through the placement test in an institute. Their reading comprehension ability with the f...

Small mobile devices are ubiquitous and must be designed with great care. One of the most serious challenges is how information on the small displays is presented optimally. This paper addresses the special problem of the increasing number of aged users. On the one hand, information displayed should be easily readable. This requires a low information density and a sufficiently large font size. ...

Topological indices are numerical parameters of a molecular graph G which characterize its topology. On the other hands, computing the connectivity indices of molecular graphs is an important branch in chemical graph theory. Therefore, we compute First Zagreb index Zg   <span style="font-family: TimesNewRomanPS-Italic...
