% No short abstract should be added in the extended abstract.

\section{Text}

The extended abstract should be written using 11pt font size and be 1.25 spaced. The proper length for the extended abstract is up to 4 pages. No short abstract should be added.

The first paragraph of each section has no indentation. The following paragraphs are indented. In Word, this is better done using the ruler (or by copying the paragraph mark for an indented paragraph, or by just entering carriage return at the end of the previous indented paragraph) than adding multiple spaces.

Divide your extended abstract into clearly defined and numbered sections and subsections (if needed). Subsections should be numbered 1.1 (then 1.1.1, 1.1.2, ...), 1.2, etc. Note that the Reference section must be not included in section numbering. Use this numbering also for internal cross-referencing. All sections and subsection may be given a brief heading, while each heading should appear on its own separate line.

State clearly the objectives and provide an adequate background. Avoid extensive citations and discussion of published literature. Results should be clear and concise. The main conclusions may be presented in a short Conclusions section, which may stand alone or form a subsection of a Discussion or Results and Discussion section.

Number tables (if any) consecutively in accordance with their appearance in the text. Be sparing in the use of tables. In addition, ensure that each illustration-figure (if any) has a numbered caption. Supply captions separately, not attached to the figure. A caption should comprise a brief title. Finally, note that both figures and tables must have a centered alignment.

Please ensure that every reference cited in the text is also present in the reference list (and vice versa). Indicate references by number(s) in square brackets in line with the text. The actual authors can be referred to, but the reference number(s) must always be given. Number the references (numbers in square brackets) in the reference list in the order in which they appear in the text. The literature format and reference style is provided in \cite{ArtInJour}, \cite{Book}, \cite{ChInABook}, \cite{ArtInProc}, \cite{Dissertation}, \cite{WorkPaper} and \cite{PresAtAConf}.
