\section{Introduction}

The 5th International Conference on Scientific Computing in
Electrical Engineering SCEE 2004 will be organised from 5 to 9
September, 2004, in Capo D'Orlando, Italy. This conference, which
has been organised twice before as a German conference and form
2000 as an international conference, will again aim at an
international audience. To stress this fact, the conference will
this year be organised in Italy. We aim to reach both
mathematicians and electrical engineers, both from industry and
from the academic world.

This is an example poster for the SCEE-2004 Conference. It is
created on A4 format, but can be printed on A1 format to give a
typical poster. Of course, you are free to modify this basic
outline at will.

\section{Equations}
The Maxwell equations are given below.

\begin{subequations}
\begin{align}
\rot \mathbf{E} &= - \frac{\partial \mathbf{B}}{\partial t}, \label{eq:maxwell1} \\
\rot \mathbf{H} &= \mathbf{J} + \frac{\partial \mathbf{D}}{\partial t}, \label{eq:maxwell2} \\
\div \mathbf{D} &= \rho, \label{eq:maxwell3} \\
\div \mathbf{B} &= 0. \label{eq:maxwell4}
\end{align}
\end{subequations}
Note that we can refer to individual equations, such as
\eqref{eq:maxwell3} or \eqref{eq:maxwell4}. It is also possible to
include tables.

$\mathbf{D}$ & electric flux & $\frac{\mathrm{C}}{\mathrm{m}^2}$(Coulomb per square meter)\\[2mm] \hline
$\mathbf{B}$ & magnetic flux & $\mathrm{T}$ (Tesla) \\[2mm] \hline
$\mathbf{J}$ & electric current & $\frac{\mathrm{A}}{\mathrm{m}^2}$(Ampere per square meter)\\[2mm] \hline
$\rho$ & electric charge & $\frac{\mathrm{C}}{\mathrm{m}^3}$(Coulomb per cubic meter)\\[2mm] \hline
\end{tabular}
\end{center}

\section{Topics}
The SCEE2004 conference will address the following topics:
\begin{itemize}
\item Electromagnetics
\item Circuit simulation
\item Coupled problems
\item Generic Mathematical and Computational Methods
\end{itemize}

\section{More on figures}
It is possible to include PostScript figures in a poster. It is
also possible to include colored figures.\\[2mm]

\section{Conclusions}
We hope it is clear how to create a poster. With the example
poster provided, it is possible to create a poster that includes
text, equations and figures.
