+% Some very useful LaTeX packages include:
+% (uncomment the ones you want to load)
+
+
+% *** MISC UTILITY PACKAGES ***
+%
+%\usepackage{ifpdf}
+% Heiko Oberdiek's ifpdf.sty is very useful if you need conditional
+% compilation based on whether the output is pdf or dvi.
+% usage:
+% \ifpdf
+% % pdf code
+% \else
+% % dvi code
+% \fi
+% The latest version of ifpdf.sty can be obtained from:
+% http://www.ctan.org/pkg/ifpdf
+% Also, note that IEEEtran.cls V1.7 and later provides a builtin
+% \ifCLASSINFOpdf conditional that works the same way.
+% When switching from latex to pdflatex and vice-versa, the compiler may
+% have to be run twice to clear warning/error messages.
+
+
+
+
+
+
+% *** CITATION PACKAGES ***
+%
+%\usepackage{cite}
+% cite.sty was written by Donald Arseneau
+% V1.6 and later of IEEEtran pre-defines the format of the cite.sty package
+% \cite{} output to follow that of the IEEE. Loading the cite package will
+% result in citation numbers being automatically sorted and properly
+% "compressed/ranged". e.g., [1], [9], [2], [7], [5], [6] without using
+% cite.sty will become [1], [2], [5]--[7], [9] using cite.sty. cite.sty's
+% \cite will automatically add leading space, if needed. Use cite.sty's
+% noadjust option (cite.sty V3.8 and later) if you want to turn this off
+% such as if a citation ever needs to be enclosed in parenthesis.
+% cite.sty is already installed on most LaTeX systems. Be sure and use
+% version 5.0 (2009-03-20) and later if using hyperref.sty.
+% The latest version can be obtained at:
+% http://www.ctan.org/pkg/cite
+% The documentation is contained in the cite.sty file itself.

+% ^------------^------------^----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

-This paper is dedicated to the design of chaotic random generators
-and extends previous works proposed by some of the authors.
-We propose a theoretical framework proving both the chaotic properties and
-that the limit distribution is uniform.
-A theoretical bound on the stationary time is given and
-practical experiments show that the generators successfully pass
-the classical statistical tests.
+ Designing a pseudorandom number generator (PRNG) is a
+difficult and complex task. Many recent works have considered chaotic
+functions as the basis of built PRNGs: the quality of the output would
+indeed
+be an obvious consequence of some chaos properties. However, there is
+no direct reasoning that goes from chaotic functions to uniform
+distribution of the output.
+Moreover,
+embedding such kind of functions into a PRNG does not necessarily
+allow to get a chaotic output,
+which could be required for simulating some chaotic behaviors.
+
+In a previous work, some of the authors have proposed the idea of
+walking into a $\mathsf{N}$-cube where a balanced Hamiltonian cycle
+has been removed as the basis of a chaotic PRNG. In this article, all
+the difficult issues observed in the previous work have been
+tackled. The chaotic behavior of the whole PRNG is proven. The
+construction of the balanced Hamiltonian cycle is theoretically and
+practically solved. An upper bound of the expected length of the walk
+to obtain a uniform distribution is calculated. Finally practical
+experiments show that the generators successfully pass the classical
+statistical tests.

+% The very first letter is a 2 line initial drop letter followed
+% by the rest of the first word in caps.
+%
+% form to use if the first word consists of a single letter:
+% \IEEEPARstart{A}{demo} file is ....
+%
+% form to use if you need the single drop letter followed by
+% normal text (unknown if ever used by the IEEE):
+% \IEEEPARstart{A}{}demo file is ....
+%
+% Some journals put the first two words in caps:
+% \IEEEPARstart{T}{his demo} file is ....
+%
+% Here we have the typical use of a "T" for an initial drop letter
+% and "HIS" in caps to complete the first word.
+% \IEEEPARstart{T}{his} demo file is intended to serve as a ``starter file''
+% for IEEE journal papers produced under \LaTeX\ using
+% IEEEtran.cls version 1.8b and later.
+% % You must have at least 2 lines in the paragraph with the drop letter
+% % (should never be an issue)
+% I wish you the best of success.

+% % (The subfig.sty package must be loaded for this to work.)
+% % The subfigure \label commands are set within each subfloat command,
+% % and the \label for the overall figure must come after \caption.
+% % \hfil is used as a separator to get equal spacing.
+% % Watch out that the combined width of all the subfigures on a
+% % line do not exceed the text width or a line break will occur.

+% %
+% % 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.
+% % Be aware that for subfig.sty to generate the (a), (b), etc., subfigure
+% % labels, the optional argument to \subfloat must be present. If a
+% % subcaption is not desired, just leave its contents blank,
+% % e.g., \subfloat[].
+
+
+% % An example of a floating table. Note that, for IEEE style tables, the
+% % \caption command should come BEFORE the table and, given that table
+% % captions serve much like titles, are usually capitalized except for words
+% % such as a, an, and, as, at, but, by, for, in, nor, of, on, or, the, to
+% % and up, which are usually not capitalized unless they are the first or
+% % last word of the caption. Table text will default to \footnotesize as
+% % the IEEE normally uses this smaller font for tables.
+% % The \label must come after \caption as always.
+% %
+% %\begin{table}[!t]

+% % Note that the 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 typically not used, but it
+% % is allowed and encouraged for Computer Society conferences (but
+% % not Computer Society journals). Most IEEE journals/conferences use
+% % top floats exclusively.
+% % Note that, LaTeX2e, unlike IEEE journals/conferences, places
+% % footnotes above bottom floats. This can be corrected via the
