Question

How can I prevent the new line indicated in the picture below?

enter image description here

Here is a MWE:

\documentclass[svgnames,9pt]{beamer}
\usepackage[latin1]{inputenc}
\usetheme{Warsaw}
\setbeamertemplate{headline}{}
\setbeamerfont{footline}{size=\fontsize{6}{8}\selectfont}
\makeatletter
\setbeamertemplate{frametitle}
{%
  \nointerlineskip%
  \vskip-2pt%
  \hbox{\leavevmode
    \advance\beamer@leftmargin by -12bp%
    \advance\beamer@rightmargin by -12bp%
    \beamer@tempdim=\textwidth%
    \advance\beamer@tempdim by \beamer@leftmargin%
    \advance\beamer@tempdim by \beamer@rightmargin%
    \hskip-\Gm@lmargin\hbox{%
      \setbox\beamer@tempbox=\hbox{\begin{minipage}[b]{\paperwidth}%
          \vbox{}\vskip.50ex% NEW: original \vskip-.75ex

          \insertframetitle%
          \ifx\insertframesubtitle\@empty%
            \strut\par%
          \else
            \par{\usebeamerfont*{framesubtitle}{\usebeamercolor[fg]{framesubtitle}\insertframesubtitle}\strut\par\vskip2ex}% NEW: added \vskip2ex
          \fi%
          \nointerlineskip
          \vbox{}%
          \end{minipage}}%
      \beamer@tempdim=\ht\beamer@tempbox%

Sorry, but I don't understand why you don't customize the title page with the apposite title page template. An example: How to customize \titlepage in beamer?. BTW: you might be interested in an italian guide called Introduzione alla personalizzazione di Beamer. — Claudio Fiandrino, Dec 04 '12 at 11:19
@ClaudioFiandrino - I just wanted to use my personal layout, is it such a bad habit doing it this way?.thks for pointing out the tutorial. — Matteo, Dec 04 '12 at 11:22
@ClaudioFiandrino - BTW, I used the \mbox{} command and the line will not be broken, however it is not centred (even though I put the \centering command). How can I solve the problem? — Matteo, Dec 04 '12 at 11:24
Have you tried with Master Thesis in Computer Science~Engineering? — Claudio Fiandrino, Dec 04 '12 at 11:26
@ClaudioFiandrino - yes, but it produced the following effect: Master Thesis in Computer\\Science Engineering. (I put \ where the new line occurs) — Matteo, Dec 04 '12 at 11:30
Personally, I think it is better to create a new theme, even starting by a default one, by logically dividing things into inner, outer, color and font theme. This helps a lot in keeping the code clean. But, in the current case you solve your problem by simply increasing the width of the minipage: for example from 0.5\textwidth up to 0.6\textwidth. — Claudio Fiandrino, Dec 04 '12 at 11:47

Change

\begin{minipage}[b]{0.5\textwidth}
    \centering
    University of Siena\\Master Thesis in Computer Science Engineering
\end{minipage}%

to

\begin{minipage}[b]{0.7\textwidth}
    \centering
    University of Siena\\Master Thesis in Computer Science Engineering
\end{minipage}%

as you do not want to force the title to fit into half the page width.
