\subsubsection*{ABSTRACT [HEADING 1 STYLE]}

[Body Text style] Document abstract goes here. It should include a concise description of the results and findings of the research.

Nam ultrices wisi. Mauris tempor dolor nec tellus. Proin in nulla. In ultrices scelerisque massa. Nam suscipit porttitor lorem. In sit amet lorem et tellus tempus tempor. Suspendisse egestas. Praesent ultricies dolor a ante. Etiam tincidunt, dui eget vestibulum feugiat, magna enim ultricies lectus, sed condimentum purus diam a neque. Aliquam cursus.

\paragraph{KEYWORDS:} \emph{At least 3} keywords are required with all letters in lower case and not bold. Careful consideration should be given to selection of keywords as they will be used to generate the Keywords Index for the proceedings volume. A list of suggested keywords is provided at the end of the IAFSS8\_Author Instructions document. It is recommended that you select at least one of these words. If you already have a keyword that has the same meaning as one of the words on the list, use the word provided on the list.

\subsubsection*{NOMENCLATURE LISTING (IF APPLICABLE) [HEADING 1 STYLE]}

If symbols are used extensively, a nomenclature listing, arranged alphabetically, must be included in the paper immediately following the Keywords listing. All subscript and superscript symbols appear separately in the listing. If units of measure are provided, place them in parentheses next to the applicable term. A table, as provided below, can be used to simplify two column layout of nomenclature list.

\begin{tabular}{ll}
\begin{tabular}{ll}
$a$ & apparatus dimension (m) \\
$c_p$ & heat capacity (kJ/kg/K) \\
$H$ & half-length of the window (m)\\
$h$ & heat transfer coefficient (W/m$^2$/K)\\
$I$ & absorbed radiant heat flux (kW/m$^2$)\\
$k$ & thermal conductivity (W/m/K) \\
$L$ & glass thickness (m) \\
$l$ & decay length (m)\\
$q$ & heat flux (kW/m$^2$)\\

\subsubsection*{OPTIONAL DOCUMENT COMPONENTS}

\vspace{.5\parskip}
\subsubsection*{Abbreviations and acronyms}

Write out abbreviations or acronyms at their first mention in the text followed by the abbreviation or acronym in parenthesis.

\subsubsection*{Symbols}

Symbols in the text of the document should be italic.  Symbols must be defined either in the text or in a Nomenclature Listing table.  Symbol definitions should include the units of the symbol.

\subsubsection*{Equations [Equation Style]}

Equations are numbered consecutively in the text and referred to as Eq. 1, etc. If the equation reference is the first word in a sentence, then spell the word Equation. An Equation style has been provided which includes a right aligned tab stop for the equation number and extra space after the paragraph.

\begin{equation}
\label{eqn_dmdt}
\frac{\d m_1}{\d t} = - \left\{ k_1(T) + k_2(T)\right\}m_1 \,\mbox{,} \quad 
\frac{\d m_2}{\d t} = k_2(T) m_1 \,\mbox{,} \quad
\frac{\d T}{\d t} = H
\end{equation}

\begin{equation}
\label{eqn_m}
m(T_c) = m_1(T_c) + m_2(T_c) = \frac{r+1}{2} \,\mbox{.}
\end{equation}

%\begin{equation}
%\label{eqn_multiline}
%\begin{array}{lcl}
%y &=& mx + b \,\mbox{,}\\
%\displaystyle \frac{\d x}{\d t} &=& u \,\mbox{.}

\subsubsection*{Figures}

\begin{itemize}
\item All figures must have a number and caption [Caption style], i.e., Fig. 1. Fire in unoccupied building. A single space separates the word Fig. and the figure number, as well as the figure number and caption. Number figures consecutively with Arabic numerals. \vspace{-\parskip} 
\item Figure captions should be as concise as possibleÑdetailed information/descriptions about the figures should be given in the text. \vspace{-\parskip} 
\item Figure captions are centered below the figure, in sentence case with a period at the end. \vspace{-\parskip} 
\item In the text, references to figures are numbered consecutively and referred to as Fig. 1, etc. If the figure reference is the first word in the sentence, then spell out the word Figure. \vspace{-\parskip} 
\item Figures are centered. \vspace{-\parskip} 
\item In Word 2000, pictures are inserted Òin line with text.Ó Whenever possible, this option should be applied to pictures to minimize unexpected movement of surrounding text. \vspace{-\parskip}

\subsubsection*{Tables}

\begin{itemize}
\item All tables must have a number and title [Table Title style], i.e., Table 1. Heat fluxes selected for the preheating region. A single space separates the word Table and the table number as well as the table number and title. Number tables consecutively with Arabic numerals. \vspace{-\parskip}
\item Table titles should be as concise as possibleÑdetailed information/descriptions about the tables should be given in the text. \vspace{-\parskip}
