% note the % following the last \IEEEmembership and also \thanks - 
% these prevent an unwanted space from occurring between the last author name
% and the end of the author line. i.e., if you had this:
% 
% \author{....lastname \thanks{...} \thanks{...} }
%                     ^------------^------------^----Do not want these spaces!
%
% a space would be appended to the last name and could cause every name on that
% line to be shifted left slightly. This is one of those "LaTeX things". For
% instance, "\textbf{A} \textbf{B}" will typeset as "A B" not "AB". To get
% "AB" then you have to do: "\textbf{A}\textbf{B}"
% \thanks is no different in this regard, so shield the last } of each \thanks
% that ends a line with a % and do not let a space in before the next \thanks.
% Spaces after \IEEEmembership other than the last one are OK (and needed) as
% you are supposed to have spaces between the names. For what it is worth,
% this is a minor point as most people would not even notice if the said evil
% space somehow managed to creep in.

% An example of a floating figure using the graphicx package.
% Note that \label must occur AFTER (or within) \caption.
% For figures, \caption should occur after the \includegraphics.
% Note that IEEEtran v1.7 and later has special internal code that
% is designed to preserve the operation of \label within \caption
% even when the captionsoff option is in effect. However, because
% of issues like this, it may be the safest practice to put all your
% \label just after \caption rather than within \caption{}.
%
% Reminder: the "draftcls" or "draftclsnofoot", not "draft", class
% option should be used if it is desired that the figures are to be
% displayed while in draft mode.

% Note that IEEE typically puts floats only at the top, even when this
% results in a large percentage of a column being occupied by floats.


% An example of a double column floating figure using two subfigures.
% (The subfig.sty package must be loaded for this to work.)
% The subfigure \label commands are set within each subfloat command, the
% \label for the overall figure must come after \caption.
% \hfil must be used as a separator to get equal spacing.
% The subfigure.sty package works much the same way, except \subfigure is
% used instead of \subfloat.

%\caption{Simulation results}

%\end{figure*}
%
% Note that often IEEE papers with subfigures do not employ subfigure
% captions (using the optional argument to \subfloat), but instead will
% reference/describe all of them (a), (b), etc., within the main caption.


% An example of a floating table. Note that, for IEEE style tables, the 
% \caption command should come BEFORE the table. Table text will default to
% \footnotesize as IEEE normally uses this smaller font for tables.
% The \label must come after \caption as always.
%
%\begin{table}[!t]
%% increase table row spacing, adjust to taste
%\renewcommand{\arraystretch}{1.3}
% if using array.sty, it might be a good idea to tweak the value of

%\hline
%\end{tabular}
%\end{table}


% Note that IEEE does not put floats in the very first column - or typically
% anywhere on the first page for that matter. Also, in-text middle ("here")
% positioning is not used. Most IEEE journals use top floats exclusively.
% Note that, LaTeX2e, unlike IEEE journals, places footnotes above bottom
% floats. This can be corrected via the \fnbelowfloat command of the
% stfloats package.

The problem is that when I make a preview of this, I get indentation(for two lines) in the paragraph just after the list. I don't want that. How can I remove that? I am new to LaTeX. Please help. Here's the screenshot of generated pdf. Generated PDF

Welcome to TeX.SX! Have you tried to use \noindent ? –  Alexis Pigeon Dec 4 '13 at 17:33
    
Yes. I did. In addition I also tried putting the % after \end{enumerate}, so that the blank space don't count. No use. –  Iceman Dec 4 '13 at 17:40
    
@AdityaTyagi: Without a full minimal working example (MWE) it's hard to tell what's causing the problem. What packages have you loaded? When I compile your code, adding \documentclass{article}\begin{document}...\end{document}, I don't have the problem you showed. –  Kevin C Dec 4 '13 at 17:41

The culprit is the \IEEEPARstart. Despite what the style file says this has not been fixed to allow direct inclusion of environments in the initial paragraph. To work around this you can just make sure there is a \par before your enumerate. Here is the same text first time without \par, second time with:

I guess I was still testing this when you had already answered. I'm leaving my answer because it explains why the \par invoked by enumerate doesn't already cure things. By the way, I had to scroll 6 screens to the right to see the \par you added. A blank line would have been easier to see. –  Dan Dec 4 '13 at 19:36

Thanks a lot. You just saved a guy from switching back to MS Word. –  Iceman Dec 4 '13 at 21:17
    
@Dan Your answer is a nice complement. I have refilled the code lines so you no longer need to scroll to the right. I used \par rather a blank line to indicate it really is a work around. –  Andrew Swann Dec 5 '13 at 9:49

I think this is a bug in IEEEtran.cls in the macro \IEEEPARstart. You can get around it by putting a blank line after \end{enumerate} and putting \noindent at the start of the following paragraph.

The problem comes down to the two parameters \hangindent and \hangafter. These are given values that allow the large T to fit into the two-line indentation in the first paragraph. These values must persist until the end of the paragraph, because only when the full paragraph is collected does TeX break it into lines using these values to get the lengths of the first two lines.

These values are reset to zero at the end of the paragraph, more specifically, at the first invocation of the TeX "end-of-paragraph" primitive. Unfortunately, in this example, that happens inside a group and the reset values are lost. Thus, the paragraph that follows has those same values and you get the same two lines of indentation as were used earlier to place that large T.

Another workaround is to put the following right after \end{enumerate}:

\makeatletter \@@par \makeatother

This invokes the primitive end-of-paragraph but not \par itself, so that the values of \hangindent and \hangafter are restored to 0, but the magic that keeps the next line from indenting remains in effect.
