I have to insert the cover page of my thesis as a title page, so it will also move from the center of the page to openright, I guess.
The titlepage code is this:
\begin{titlepage}
\begin{center}
{{\Large{\textsc{Alma Mater Studiorum $\cdot$ Universit\`a di
Bologna}}}} \rule[0.1cm]{15.8cm}{0.1mm}
\rule[0.5cm]{15.8cm}{0.6mm}
{\bf FACULTY OF ENGINEERING \\ Master degree in Electrical Engineering\\
\small{Curriculum:\\ Electronic systems for information processing}}
\end{center}
\vspace{15mm}
\begin{center}
{\LARGE{\bf Power consumption analysis }}\\
\vspace{3mm}
{\LARGE{\bf for self diagnosis of }}\\
\vspace{3mm}
{\LARGE{\bf Wireless Sensor Nodes}}\\
\vspace{19mm} {\large{\bf Master thesis in Electronic Calculators M}}
\end{center}
\vspace{40mm}
\par
\noindent
\begin{minipage}[t]{0.50\textwidth}
{{\bf Supervisors:\\ \large{Prof. Salmon Cinotti Tullio \\ Dr. Aly Aamer Syed}}}
\end{minipage}
\hfill
\begin{minipage}[t]{0.47\textwidth}\raggedleft
{{\bf Author:\\
\large{Bacchiani Claudio}}}
\end{minipage}
\vspace{20mm}
\begin{center}
{\large{\bf Session 1\\ Year 2011-2012}}
\end{center}
\end{titlepage}
When this is used as cover it works well, but if I \include it in the thesis it comes out oddly centered:

The preamble of the document, packages excluded, looks like this:
\documentclass[12pt, a4paper, titlepage, twoside, openright]{book}
\usepackage{graphicx} %Figures management
\linespread{1.2}
Can I get it centered without having to include it as a pdf page?
Even better, can I reuse the code for the cover and the title page, and just changing settings externally?
