An IMACS Journal

General

Contributions should be written in English, and submitted via the journal's online submission and peer-review system at http://ees.elsevier.com/apnum. Please follow the instructions given on this site. Please note that the publication of papers will be delayed if they are missing any author information (e.g. e-mail addresses) or contain poor quality artwork.

Authors will upload their manuscript and its associated artwork. An electronic (PDF) proof is generated and the reviewing process is carried out using that PDF.LaTeX manuscripts should be prepared using the BibTeX style file elsart-num-sort.bst available at: ftp://ftp.tex.ac.uk/tex-archive/bibliography/bibtex/contrib/elsevier/elsart-num-sort.bst or from the Comprehensive TeX Archive Network (CTAN) sites.

All material received will be reviewed as rapidly as possible.

No page charge is made. Twenty-five offprints of each contribution are available free of charge. Additional offprints can be ordered. Please make sure that the paper is submitted in its final form. Corrections in the proof stage, other than printer's errors, should be avoided: costs arising from such corrections will be charged to the authors.

Upon acceptance of an article, the author(s) will be asked to transfer copyright of the article to the Publisher. This transfer will ensure the widest possible dissemination of information. Manuscripts should be prepared for publication in accordance with instructions given in the "Guide for Authors" (available from the Publisher) details of which are given below.

Footnotes should be avoided if possible and be as brief as possible, they should be numbered consecutively.

An abstract of 10 to 20 typed lines written by the author will precede and introduce each article. Keywords should be listed.
Special care should be given to the preparation of the drawings for figures and diagrams. Except for a reduction in size, they will appear in final printing in exactly the same format as submitted by the author; normally they will not be redrawn by the printer. In order to make a photographic reproduction possible, all drawings should be on separate sheets,with wide margins, drawn large size, and of good quality. Exceptions are diagrams only containing formulae and a small number of straight lines (or arrows): these can be typeset.
References should be listed alphabetically, as in the following examples: books [1], articles in journals [2], papers in a contributed volume [3,4], unpublishedpapers [5].

Illustrative material (original figures or high-quality glossy prints, or photographs showing a sharp contrast) should be included separately. No changes from the accepted version are permissible, without the explicit approval by the Editors. The Publisher reserves the right to decide whether to use the author's file or not. If the file is sent by e-mail, the full name of the journal should be mentioned in the subject field of the message to identify the paper. Authors should include an ASCII table (available from the Publisher) in their files to enable the detection of transmission errors.

For the purpose of further correspondence the manuscript should end with a complete mailing address, including email address, of at least one of the authors. Return to top of document

Electronic submission: Non-LaTeX documents

Only the final accepted manuscript can be submitted on disk, along with a paper-printed version which is identical to the file. Please label the disk with your name, and mention which word processor you have used. The word-processed text should be in single column format. Keep the layout of the text as simple as possible; in particular, do not use the word-processor's options to justify the text or to hyphenate the words.

The electronic text should be prepared in a way very similar to that of conventional manuscripts (see also Guide for Authors). The list of references, tables and figure legends should be compiled separately from the main text. Do not reserve space for the figures and tables in the text; instead, indicate their approximate locations, either directly in the electronic text or on the manuscript.
