\section{Introduction}
In 1912, Conrad Schlumberger (1878-1932), professor at the Ecole des Mines de
Paris (now MINES Paristech), made the first electric field imaging experiment
at his family house in Val Richer, in Normandy. This offered new possibilities
for exploring the Earth. Over the last 100 years, electrical imaging has grown
to be used in many other fields such as medical and process tomography


To celebrate this innovation, a workshop will be held with the goal of
\begin{itemize}
\item
Celebrate the 100th anniversary of the first electrical imaging experiment
\item
    Bring together the disparate electrical imaging communities (geophysical,
medical and industrial process imaging, as well as other specialist
applications)
\end{itemize}

This is a \LaTeX{} template document for the  workshop on ``100 years of electrical imaging", 
to be held in Paris, July 9--10, 2012.

\subsection{Abstract} 

Each paper should contain an abstract of about 100--200 words at
the beginning of the paper.

\subsection{Figures} 
Figure captions should follow each figure.
For a figure such as \ref{Both-Cols-Fig}, use:
\verb+\begin{figure}+ \ldots \verb+\end{figure}+.

  \put(4.05, 1.9){$B$}
  \put(1.7, 2.95){$C$}
  \put(3.1, 2.5){$a$}
  \put(1.3, 1.7){$b$}
  \put(2.5, 1.05){$c$}
  \put( 3.3, 1){$F=\sqrt{s(s-a)(s-b)(s-c)}$}
\end{picture}

\end{figure}



\subsection{Tables} 
Tables should be centered on the page. The table caption should be below the table.

\begin{table}
\centering
%From: http://amath.colorado.edu/documentation/LaTeX/reference/tables/ex1.html
\begin{tabular}{|c|ccc|r|}
        \hline
$k$ &  $x_1^k$    &   $x_2^k$  & $x_3^k$   & remarks  \\
        \hline
0   & -0.3 & 0.6 & 0.7  &  \\
7   & 0.5 & 0          & -0.523  & $\epsilon < \xi $ \\
        \hline
\end{tabular}
\label{this-table}
\caption{Example table here}
\end{table}




\subsection{Equations}
Equations should be placed on separate lines and numbered
\begin{equation}
x(t) = s(f_\omega(t))
\label{eq1}
\end{equation}
According to equation \ref{eq1}, a residue theorem states that
\begin{equation}
\oint_C F(z)dz=2 \pi j \sum_k Res[F(z),p_k],
\label{eq3}
\end{equation}
%
\subsection{References}

List and number all references at the end of the paper. The references can be numbered in alphabetic order or in order of appearance in the document, 
for example \cite{Waspaa1} \cite{Waspaa2}. 
The reference format is the IEEE format, as illustrated
in the References section.

\begin{enumerate}
  \item Point 1
  \item Point 2
