The figure must be centered and the layout must be set to "in line with text" and not "square" or "tight" to ensure that the final printout will look the same as what you submitted. Free-floating, as well as pictures obtained by grouping several objects and/or texts together are not acceptable. A table should be used to arrange the positions of multiple figures. Figure caption, if present, should be placed directly below the figure in the form Figure 1. xxxx and center justified. Other additional sections such as references, acknowledgements, and keywords should not be present and they will not be included in the abstract book.
