    1. INTRODUCTION

    In order to communicate with the authors, the editors are asking the authors to

    write a separate file or in the emails their complete titles, positions, mail andelectronic addresses. Generally, the data is the next:

    Firstname FAMILYNAMETitle(s)Position(s)

    Personal email(s),Personal web page(s)

    DepartmentDepartments web page(s)

    Institution

    Institutions web page(s)Street address

    City, CountyPostal Code

    Country

    English is the main language for the Computational Civil Engineering 2007,International Symposium. In order to be easily readable please consider using short

    sentences and paragraphs. Scientific and technical English manuals might be veryuseful for inexperienced authors. The speller and grammar corrector of Wordare

    also important tools.

    Avoid using expressions as: I did, we did, our work, my work etc. Insteaduse impersonal expressions as: it was done, authors work, authors worketc.

    At the same time, avoid addressing directly to the reader (i.e. you) and the use of

    imperative sentences. As a paradox, this example is directly addressing to thereader and it is using imperative sentences.

    Avoid using expressions as lets do, lets see, lets state etc or their

    equivalents.

    Shortenings as dont, cant, wont etc shell notbe used. Use instead donot, cannot, will not etc.

    As a rule, never let more than one space between words.

    Please treat carefully the use of special characters as comma, full stop (point,

    period, dot), colon, semi-colon, i.e.: , . : ;. They require no space before and aspace after. Therefore the next are bad examples:

    red , green , blue

    done . Thehyposesis ; new

    follows : up , down and left

    Special attention must be given to the use of special characters that are coupled as:

    parenthesis, quotation marks, brackets, apostrophes etc. The left part must have a

    space before and no space after and the right part must have no space before and aspace after. Bad examples:

    To be or not to beDo Not Enter It was written Special Studies on that door.( it was understood)

    (and not as shown ) Last but not least Please

    Never let Figures, Tables, Equations and References un-referred. Also be carefulthat referred Figures, Tables, Equations and References really exist in your text.

    Paper format is Academic (170mm x 240mm), with 20 mm left, 20 mm right, 25mm up and 20 mm bottom margins. The .01 Paper title style uses Times NewRoman font, 14 points, line space single, alignment centered.

    Authors names are written with Times New Roman font, 12 points, line spacesingle, alignment centered, 12 points before and 6 points after, i.e. .02 Author(s)style.

    Affiliations are written using Times New Roman font, 9 points, line space single,italic, alignment centered (.03 Affiliation style), one on a line only. Shorten ifnecessary.

    However, additional or other kind of data might be used, depending on country

    and/or institution etc.

    If there is only one author or only one affiliation, do not use the superscript(exponent) for showing the affiliation.

    Table 1. Name of the table

    Col 1 Col 2 Col ..

    Name for Line 1 (if needed)

    Name for Line 1 (if needed)

    .

    Total (if needed)

    Chapters titles are using the .06 Chapter style, Times New Roman font, 13points, line space single, alignment left, 30 points before and 12 points after, allcaps. A left tab is placed at 5 mm and the hanging is also at 5 mm. The numbering

    should be made manually because in Word numbering is difficult to manipulate.

    After the number of paragraph is introduced, press a tab. For more than 9 chaptersa space must be introduced after the number of the chapter.

    Inside chapters use .07 Text style, Times New Roman font, 11 points, line space

    single, alignment justified, 6 points before. Chapters, subchapters and sub-subchapters should be manually numbered because automatic numbering and

    renumbering in Wordis cumbersome.

    2. SECOND CHAPTER

    2.1. Subchapter title

    Subchapter title uses .08a Subchapter style, Times New Roman font, 12 points,line space single, alignment left, 18 points before and 6 points after. A left tab is

    placed at 8 mm and the hanging is also at 8 mm.

    2.2.1. Sub-subchapter

    In the case sub-subchapters are needed use .08b Sub-subchapter style, TimesNew Roman font, 11 points, line space single, alignment left, italic, 12 pointsbefore and 6 points after. A left tab is placed at 11 mm and the hanging is also at 11

    mm.

    2.2. Tables

    Tables should be numbered and centered, written with .09 Table text style,Times New Roman font, 10 points, without vertical lines. Use Table 1 as anexample, where Table Simple 1 in Word was employed.

    Also, use the .10 Table name style (Times New Roman font, 10 points, centered,12 points before) for the name of the table.

    Please let a .18 Half line style line (Times New Roman font, 6 points) free after aTable. Refer to Table 1 into your comment about the table.

    2.3. Equations

    Equations are centered and numbered at the right (.11 Equation style). The nextline is an example.

    gumkuucum (12)

    The Equation line has a centered tab at 65 mm and a right tab at 130 mm. Please

    set theFull size at 11 points in the Equation Editor ofWord. Let the other settings

    unchanged (i.e. Subscript 7 points, Sub-subscript/superscript 5 points, Symbol18, Sub-symbol - 12). In some cases you might use other styles if you think thereis no way to correctly write your text.

    Please refer as Equation (12) in your commentary about the above sampleequation.

    2.4. Figures

    Insert figures centered, using the .12b Figures image style (Times New Romanfont, 11 points, centered, 12 points before). Number and explain it after, using the

    .12a Figure's name style (Times New Roman font, 10 points, centered, 6 pointsbefore, 12 points after).

    Figure 1. Figures comment

    Insert and center your Figure. The above example shows a Figure and itsexplanation (name or comment).

    The use of colors in Figures is encouraged. However, in the case that some wouldlike to have a printed copy of your paper, please imagine some colors or signs thatcan make readable the paper even for grey nuances printing.

    2.5. Headers and footers

    First page is using a different header than the rest of the text. The style dedicated toit, is named .14 First page header.

    This style is wich is 9.5 points Arial font, centered, colordark teal.

    Even headers are dedicated to the author(s) name(s). Only the initial(s) for the firstname and the full family name(s) are written. If there is more than one author, then

    the names should be separated by commas. The word and will not be used. The

    style for even headers is .14 Even header, i.e. Times New Roman font, 9 points,with a right tab at 130 mm. Place the page number left aligned and the name(s)right aligned.

    Odd headers are using .15 Odd header style, Times New Roman font, 9 points,with a right tab at 130 mm. This is the place for writing the Symposiums name.Place the page number right aligned and the Symposiums name right aligned.

    In fact .14 Even header and .15 Odd header styles are identical.

    Footers are not used.

    2.6. References

    For the references title, use the .13a References title style (Times New Romanfont, 12 points, line space single, 18 points before and 6 points after, leftalignment).

    Use the 13b References style for the references (Times New Roman font, 9points, line space single, justified) and numbering. In this example a book onStructural Dynamics, [1], is the first reference.

    2.7. Lists

    This is a small example of using the style .19a Dot list, Times New Roman font,11 points, justified, 5 mm left indented marker, text tab after 8 mm, text indent 8

    mm: figures; tables; equations; headers and footers;

    references; lists.

    Another idea of list is similar but it is using a dash line, .19b Dash list stylewhere the used symbol is a dash:

    - figures,- tables,- equations,- headers and footers,- references,

    - lists.

  • 8/22/2019 Templates for Homework 1

    7/72

    Computational Civil Engineering 2007, International Symposium 7

    The same but using small rectangles, the .19c Rectangle list style: figures tables

    equations headers and footers references lists.

    For a numbered list use .19d Numbered list style. Because automatic numberingand renumbering in Wordis cumbersome this kind of list might be used only once.

    For more than one numbered list use the simple list and number it manually.Example of numbered list:

    1.figures.

    2.tables.3.equations.4.headers and footers.5.references.6.lists.

    A simple list is defined using the style .19e Simple list. This can be manuallynumbered (or other kind of order method). Example:

    figures tablesr) equations

    2. headers and footersix - references

    45 lists.

    Depending on the author feeling about what is suitable for the text, the finalcharacter at the end of each line of a list can be semi-colon, comma, dot (full

    point), or can be missing except for the final line were it must be a dot (full point).

    3. CONCLUSIONS

    This is an example for writing a paper for the Computational Civil Engineering2007, International Symposium in Microsoft Word for Windows. The use of

    Task Bar or the button in Wordfor revealing the styles is very important.

    Scientific, technical and academic writing is required. English is the main language

    of the Journal. However, other international languages are accepted, too.

    Acknowledgements

    In the case there is a need for additional titles as Acknowledgements orAppendix, Appendices, Annex, Annexes, the style for titles must be the

    same as for references title, .13a References title. Inside this type of section, .07Text style is used. The acknowledgments should be placed before the references.
