\maketitle

Please follow these instructions when sending your abstract to ISIPTA '15.
We plan to produce proceedings with a book appearance and not a collection of papers and abstracts written with different formats, so it is very important that you follow these guidelines.

The easiest way to produce an abstract that satisfies these requirements is to use \LaTeX\ with the \texttt{isipta2015.sty} style.
There are instructions on this at the end of \texttt{isipta15.pdf}, the instructions for paper authors.

You can use this document as a guide when you are producing your abstract.
It is typeset according to the instructions it contains; your abstract should have the same appearance as this document.

\paragraph{General Instructions}
All abstracts must be in English.
An abstract must not be longer than one page.
No page number should be present on the the page.
After you have finished your abstract and checked that it complies with these instructions, produce a PDF file and consult the ISIPTA web site
at \texttt{https://www.sipta.org/isipta15} for detailed instructions on how to send us your abstract.

Text must be justified, in two-column format.
All text must be 10-point, single-spaced type, with 12-point vertical spacing, using either Computer Modern or Times Roman fonts.
Do not use colored text.

Use one-half line space between paragraphs, with no indent.
Only use `paragraphs', i.e., bold run-in heads for sectioning, if needed.

Leave a blank line after the abstract (height equivalent to 12 points) and then place the keywords.
Type the word ``Keywords'' in 10-point bold font, followed by a dot, and then followed by three to ten keywords.

The height of the text must be 23.5\,cm; width must be 17\,cm.
Separation between columns must be 0.7\,cm.
Top margin must be 3\,cm and left margin must be 2.5\,cm.

\paragraph{On the Title and the Authors}
If you are not using \LaTeX, please take some time to compose the heading of your abstract.

Place the sentence ``9th International Symposium on Imprecise Probability: Theories and Applications, Pescara, Italy, 2015'' with 8-point
type, centered.
Skip 3 points and then place a black horizontal rule, 0.5\,mm tall.
Skip 0.7\,cm and place the title, centered, with bold 16-point type.
All words in the title should have initial caps (exceptions can be made
to small words).

Authors' names are centered, initials are capitalized.
The lead author's name is  to be listed first (left-most), followed by the co-authors' names.

\paragraph{On References}
List all your references in alphabetical order, at the end of the abstract.
You can use any style for references, as long as you use it consistently.
Preferably, references should be numbered according to their place in the bibliography, not the order they appear in the text.
In the main text, references could appear as \cite{first} and \cite{second}, or perhaps as (TheAuthor 1996) and (Another 1800).
Please see below for examples of possible references to articles and books.

\paragraph{Summary and Conclusions}
Any questions regarding the format of the abstracts or the \LaTeX\ style can be directed by email to the scientific program contact.
