SOURCE: bare_conf.tex from IEEE

For over three affiliations, or if they all won't fit within the width of the page, use this alternative format:

\begin{document}

\title{Paper Title*\\
{\footnotesize \textsuperscript{*}Note: Sub-titles are not captured in Xplore and
should not be used}
\thanks{Identify applicable funding agency here. If none, delete this.}
}
\author{\IEEEauthorblockN{Ali\IEEEauthorrefmark{1},
Abbass\IEEEauthorrefmark{2},
sayed\IEEEauthorrefmark{3},
