\section{The First Section}
\label{sec:first}
This template file is intended to serve as a ``starter file'' for the CIE53 submissions produced under \LaTeX. Contributed papers should be maximum 10 pages long in the current \LaTeX template.
Here introduce the paper. The paragraphs continue from here and are only separated by headings, subheadings, images and formulae. Here follows further instructions for authors.
\subsection{Structure}
Follow this order when typing manuscripts: Title, Authors, Affiliations, Abstract, Keywords, Main text (including figures and tables), Acknowledgements, References, Appendix. Collate acknowledgments in a separate section at the end of the article and do not include them on the title page, as a footnote to the title or otherwise.
Bulleted lists may be included and should look like this:
\begin{itemize}
\item Bullet point one
\item Bullet point two
\end{itemize}
\subsection{Tables}
Every table should have a caption. Headings should be placed above tables. Only horizontal lines should be used within a table, to distinguish the column headings from the body of the table, and immediately above and below the table. Tables must be embedded into the text and not supplied separately. Below is an example which the authors may find useful.
\begin{table}[ht]
\centering
\caption{An example of a table.}
\label{table}
\begin{tabular}{l c c}
\hline
An example of a column heading & Column A ($t$) & Column B ($t$)\\
\hline
And an entry & 1 & 2 \\
And another entry & 3 & 4 \\
And another entry & 5 & 6 \\
\hline
\end{tabular}
\end{table}
\subsection{Construction of references}
References must be listed at the end of the paper.  Indicate references by \cite{Smith:2012qr} and \cite{Smith:2012qr, Smith:2013jd} in the text. 
\subsection{General guidelines for the preparation of your text}
Avoid hyphenation at the end of a line. Symbols denoting vectors and matrices should be indicated in bold type. Scalar variable names should normally be expressed using italics. Weights and measures should be expressed in SI units. All non-standard abbreviations or symbols must be defined when first mentioned, or a glossary provided.
\subsection{Footnotes}
Footnotes should be avoided if possible. Necessary footnotes should be denoted in the text\footnote{Footnote text.}. 
The footnotes should be typed single spaced, and in smaller type size (8 pt), at the foot of the page in which they are mentioned, and separated from the main text by a one line space extending at the foot of the column. The Els-footnote style is available in the MS Word for the text of the footnote.
Please do not change the margins.
\section{Illustrations}
\label{sec:illustrations}
Every figure should have a caption. All photographs, schemas, graphs and diagrams are to be referred to as figures. Line drawings should be good quality scans or true electronic output. Low-quality scans are not acceptable. Lettering and symbols should be clearly defined either in the caption or in a legend provided as part of the figure. Figures should be placed at the top or bottom of a page wherever possible, as close as possible to the first reference to them in the paper. Please ensure that all the figures are of 300 DPI resolutions as this will facilitate good output.
The figure number and caption should be typed below the illustration in 8 pt and centered. For more guidelines and information to help you submit high quality artwork please visit: http://www.elsevier.com/artworkinstructions Artwork has no text along the side of it in the main body of the text. However, if two images fit next to each other, these may be placed next to each other to save space. For example, see Fig. 1.  
\begin{figure}[bt]
\centering\includegraphics[width=0.4\linewidth]{placeholder}
\caption{Figure caption.}
\label{figure}
\end{figure}
\section{Equations}
\begin{equation}
\label{eq:emc}
\rho=\frac{\vec{E}}{J_C(T=const.)\cdot \left( P\cdot\left( \frac{\vec{E}}{E_C} \right)^m + (1-P) \right)}
\end{equation}
\section{Conclusion}
The Conclusions section should contain a brief summary of the content and purpose of the paper, reflecting its novelty and practical significance, proposals for practical implementation of research results and providing the final word on the value of your paper.
\section*{Acknowledgments}
The purpose of the Acknowledgments section is to thank all of the people who helped with the research but did not qualify for authorship. Acknowledge anyone who provided intellectual assistance, technical help, or special equipment or materials. This section can also be used to provide information about funding by including specific grant numbers and titles. 
%% The Appendices part is started with the command \appendix;
%% appendix sections are then done as normal sections
\appendix
\section{An example appendix}
Authors including an appendix section should do so before References section. Multiple appendices should all have headings in the style used above. They will automatically be ordered A, B, C etc.
\subsection{Example of a sub-heading within an appendix}
There is also the option to include a subheading within the Appendix if you wish.
