How to write a paper for SYSID 2003 using LaTeX 2e


LaTeX issues

Use The IFAC style class and the Harvard bibliography style

The easiest way to write a properly formatted paper is to use the ifacmtg.cls LaTeX 2e class, with the default 10pt, double column style. You will also need the harvard.sty and harvard.bst packages for the bibliographical citations.

Use English hyphenation patterns

Make sure you are using hyphenation patterns for English. If you are not sure, include the english option in the documentclass command.

Include figures as Embedded PostScript files

Use embedded PostScript (eps) for your figures (you can use the graphicx or epsfig packages for this purpose). Check the size of your eps files and, if they are too big (this often happens with photographs) try to reduce their size with your favourite image processing software.

Use only valid type 1 fonts

Most LaTeX installations use the Computer Modern Fonts, designed by Donald Knuth. These fonts are usually converted to bitmaps by the dvips utility, which produces good quality prints on most printers, but render poorly on computer screens.

We advise you to use only the standard PostScript fonts with type 1 encoding. An easy way to do this is to insert the following lines in the header section of your LaTeX file (i.e. before \begin{document}):

\usepackage{times,mathptmx}
\usepackage[T1]{fontenc}
\usepackage{textcomp}

The times and mathptmx packages specify the times font family to be used for normal and math text (\textrm in LaTeX terms). You may wish to include also the helvet and courier in order to use helvetica and courier for sans-serif (\textsf) and typewriter (\texttt) text. The same effect can be obtained by processing the LaTeX file with the command

pslatex file

instead of the usual latex file. Notice that pslatex is not available for all platforms.

Generating a PostScript or PDF file from a LaTeX manuscript

The recommended procedure is to first generate a PostScript (.ps) file, and then convert it to PDF with Acrobat Distiller or GhostScript. If you cannot produce a suitable PDF file, we recommend you to submit the PostScript file.

Generating PostScript files

The standard way to produce a PostScript file from a LaTeX manuscript is to use the dvips command:

dvips file[.dvi]

If you have included the times package in your source file, you will get PostScript type 1 fonts in your .ps file, as required.

Converting PostScript files to PDF

You can convert ps files to pdf in either of the following ways:

  1. The best way to generate PDF files is to use the full Adobe Acrobat software package, which includes Acrobat Distiller, a tool for producing PDF files from PostScript files.
    You should configure the Distiller to embed and subset all fonts (set threshold level to 100%). Make sure that your generate code for Acrobat 3 (PDF 1.2)
    Adobe Acrobat is a proprietary product, and it may not be available for your platform. If you cannot produce a PDF file in this way, you are advised to submit your paper in PostScript format.
  2. Ghostscript can convert PS files to PDF. In Windows, choose

    file -> convert

    In GNU/Linux and Unix platforms, use the command:

    ps2pdf -s papersize=a4 file.ps

    Notice that this may not work well on some platforms or with some versions of the PostScript type 1 fonts.

  3. There are various sites on the worldwide web that offer free conversion to pdf.Ps2pdf.com at www.ps2pdf.com converts postscript files to pdf.

Generating PDF from LaTeX

You can generate a .pdf file instead of a .dvi file by processing your LaTeX file with pdftex:

pdflatex file.tex

This method gives excellent quality PDF files. However, EPS figures may not be included (you can convert them to PDF or JPEG), and it may not work well with the ifacmtg class. The same applies to the dvipdfm driver. We advise you to always generate a PostScript file and either submit it directly or convert it to PDF using one of the above methods.

Where to get the tools

You can download the ifacmtg class and the harvard package, as well as an example LaTeX file, from the tool repository on this site, or from any CTAN site.

The times and mathptmx packages are part of the psnfss bundle, which can be downloaded from the same sites (tool repository or CTAN ).
