All references must be numbered and cited in numerical order in the text. Authors must reference the original source of a work, not a secondary source. Classified or export-restricted references, private communications, personal Web sites, and Web sites where there is no commitment to archiving may be mentioned parenthetically in the text or in a footnote, but should not be cited in the reference list. A reference that is not reliably available is of no use to readers.
Each numbered reference citation in the text is enclosed in brackets as in the following examples:
It is shown by Smith [4] that …
The effect of … should be taken into account [5].
For example, see [6, 7].
Further documentation can be found in [8-10].
On the rare occasion when a specific page number or page range needs to accompany a citation within the text, include it within the brackets in the following manner:
This procedure was proposed by Gelb [11, p. 250].
The solution can be found in Rogers [12, pp.14-18].
When multiple author names are cited in the text, list up to two authors, as in “Walsh and Jones, ” but use “et al.” with three or more authors, as in ”Walsh et al.”
List of References
To avoid production delays, all references must be complete prior to acceptance of a manuscript. The following list gives examples of commonly lacking information:
- o All authors to a reference (do not use “et al.” in the reference list)
- o Full journal or book titles and publisher names (no abbreviations)
- o Inclusive page numbers for journals and page or chapter numbers for books
- o Journal volume and issue numbers (or months)
- o Locations of report sponsors (e.g., companies and universities)
- o Complete publishing information for proceedings (i.e., the same as for other books)
The DOI (Digital Object Identifier) should be incorporated into every reference for which it is available. A DOI is an identifier of intellectual property entities on digital networks. It provides a system for persistent identification and interoperable exchange of managed information. The use of DOIs as identifiers makes the management of intellectual property in a network environment easy and convenient and allows the construction of automated services and transactions. For more information on DOIs and their value, visit or www.crossref.org.
For all references: Spell out everything except AIAA, NASA, NACA, AGARD, and NATO; months may be abbreviated.
Follow these examples for format; double-space the reference list in your manuscript:
