How to change fonts from Times Roman to Helvetica in Latex:

Some can ask to change the font size and font type in latex. For an example, one can demand to produce the name of the title, sections, subsections and subsubsections  etc in 9pt Helvetica Bold, then do the following to fulfill the demand.

\usepackage[scaled=0.92]{helvet}

or

\usepackage{helvet}

Both the above statements are same except that the first one will scale the size of font by some amount. Now, where the change of font is desired, add the following command:

\fontfamily{Name_OF_Font_Family}\selectfont

I have changed the font type from Times Roman to Helvetica of the title of an article. I used the following way to do so.

\title{\fontfamily{phv}\selectfont{\huge{\bfseries{Parallelization of DC-Analyzer}}}}
