%
% \begin{abstract}
% \noindent
% This paper describes the implementation of the document class
% \Cname{} which has been designed for writing articles in the \Jname.
% It corresponds to \Cname{}~\fileversion, dated \filedate.
% \end{abstract}
%
%
% \section{Introduction}
% The \Jname{} (see its web page at
% \url{https://www.journals.uio.no/index.php/bioimpedance}) has
% defined a typographic style for its publication, to some extent
% based on recommendations from the \emph{US National institute of
% health}\cite{NIH}. The \LaTeX{} document class \Cname{} implements
% this style.
% As an example, this documentation uses the \Cname{} class.
%
% This \LaTeX{} code is published with a \textbf{\LaTeX{} project
% public license}, as described in
% \url{http://www.latex-project.org/lppl/}.
%
%
% \section{Usage}
% To use this document class, you must first put the
% \url{elbioimp.cls} file somewhere that \LaTeX{} can find
% it.\footnote{If you are not very familiar with your \LaTeX{}
% installation or your system administrator, you can put the
% \url{elbioimp.cls} file in the same folder as your \LaTeX{} source
% files.}
% Then you can write your \LaTeX{} document starting with
% \begin{verbatim}
%\documentclass{elbioimp}
% \end{verbatim}
% The document class is based on the standard \emph{article} class and
% is used just like that class, with three exceptions:
% \begin{enumerate}
% \item The authors' affiliations (to companies or academic institutions)
% are given with the \verb:\affiliation: command:
% \begin{verbatim}
%\author{My name\affiliation{My univerisity,
% My city, My country}}
% \end{verbatim}
% If there is more than one author, their names should be separated
% by an \verb:\and: command.
%
% If two authors have the same affiliation, the latter one may use the
% \verb:\sameaffiliation: command, as in
% \begin{verbatim}
%\author{First Author\affiliation{My university,
% My city, My country}\and
% Second Author\sameaffiliation}
% \end{verbatim}
%
% In case there should be three or more authors and some have identical
% affiliations, \verb:\sameaffiliation: may be given a
% numeric option referencing a previous author; for example, if the
% first and the third author belong to the same institution, you may
% write:
% \begin{verbatim}
%\author{A Bee\affiliation{Uni A}\and
% C Dee\affiliation{Uni B}\and
% E Eff\sameaffiliation[1]}
% \end{verbatim}
%
% \item The author may indicate keywords by empoying the
% \verb:\keyword: command.
%
% \item The document class will function poorly unless there is an
% \verb:abstract: environment and a \verb:\maketitle: command.
% \end{enumerate}
%

%
%
% \section{Class headers}
% All \LaTeXe{} class files contain a header with a set of standard
% specifications.
%
% \subsection{Class options}
% This document class has no options.
% \begin{macrocode}
\DeclareOption*{\ClassWarningNoLine
{elbioimp}{Class option \CurrentOption
\space is illegal in this document class}}
\ProcessOptions \relax
% \end{macrocode}
%
% \subsection{Base class}
% This document class is based on the standard \emph{article} class.
%
% \begin{macrocode}
\LoadClass[twocolumn]{article}
% \end{macrocode}
%
% \section{Required packages}
% A couple of standard packages are necessary to implement this class.
%
% \subsection{The \textsf{ifthen} package}
% The \textsf{ifthen} package makes testing easier.
% \begin{macrocode}
\RequirePackage{ifthen}
% \end{macrocode}
%
% \subsection{The \textsf{url} package}
% URLs should be typeset in a \textsf{Sans serif font} rather than a
% \texttt{Teletype font}.
% \begin{macrocode}
\RequirePackage[T1]{url}
\urlstyle{sf}
% \end{macrocode}
%
%
% \section{Document title area}
% The title area has its own particular design.
% It is implemented by redefining the \verb:\maketitle: command.
% \begin{macrocode}
\AtBeginDocument{\renewcommand{\maketitle}{%
\twocolumn[\begin{minipage}{\textwidth}
\renewcommand{\and}{, }
\let \thanks = \affiliation
\let \samethanks = \sameaffiliation
\renewcommand{\footnoterule}{}
\def \@makefntext ##1{\noindent
\small \@thefnmark. \it ##1}
\renewcommand{\thempfootnote}%
{\arabic{mpfootnote}}
\parindent = 0pt
{\huge \@title}\par\vspace{16pt}
{\large \@author}
\end{minipage}\par\vspace{14pt}\noindent
\elb@rule{\textwidth}\vspace{11pt}]}}
\newcommand{\elb@rule}[1]{\rule{#1}{0.6pt}}
% \end{macrocode}
% (The names \verb:\thanks: and \verb:\samethanks: are kept for
% historic reasons.)
%
% \subsection{Affiliations}
% Affiliations are specified using the \verb:\affiliation: and
% \verb:\sameaffiliation: commands.
% \begin{macrocode}
\newcommand{\affiliation}[1]{\footnote{#1}}
\newcommand{\sameaffiliation}[1][0]{%
\addtocounter{mpfootnote}{-1}%
\ifthenelse{#1<1}
{\@makefnmark}
{\@textsuperscript{\normalfont#1}}%
\addtocounter{mpfootnote}{1}}
% \end{macrocode}
%
% \subsection{Keywords}
% An additional command \verb:\keywords: makes it possible to specify
% keywords that apply to the document.
% \begin{macrocode}
\newcommand{\keywords}[1]{\def\elb@keywords{#1}}
% \end{macrocode}
%
% \subsection{Abstract}
% The abstract is typeset in \verb:\small:, and includes the keywords (if
% any).
% \begin{macrocode}
\renewenvironment{abstract}
{\small\noindent
\textbf{\abstractname}\par\vspace{1pt}
\noindent\ignorespaces}
{\par
\@ifundefined{elb@keywords}{}{%
\vspace{\baselineskip}\noindent
\textbf{Keywords:} \elb@keywords\par}
\vspace{\baselineskip}\noindent
\elb@rule{\columnwidth}}
% \end{macrocode}
%
%
% \section{Body text}
%
% \subsection{Text area}
% The text area should be in two columns and fill an A4 paper with
% margins 1.5\,cm (except the top margin, which should be 2.5\,cm).
% The gutter space should be 1\,cm.
% \begin{macrocode}
\RequirePackage[a4paper,
margin=1.5cm,top=2.5cm]{geometry}
\setlength{\columnsep}{1cm}
% \end{macrocode}
% Since the layout uses double columns, I will increase the tolerance
% for line-breaking.
% \begin{macrocode}
\pretolerance = 1000
\tolerance = 2000 \hbadness = \tolerance
% \end{macrocode}
%
%
% \subsection{Headers and footers}
% This document class has neither headers nor footers, presumably
% because the publisher will add them later.
% \begin{macrocode}
\AtBeginDocument{\pagestyle{empty}}
% \end{macrocode}
%
%
% \subsection{Text font}
% The specified journal font is \emph{Times Roman}. The
% \emph{mathptmx} packages is one of several packages that can handle this,
% but this particular package has the advantage that it also uses
% \emph{Times Roman} for the math fonts (as much as possible).
% \begin{macrocode}
\RequirePackage{mathptmx}
% \end{macrocode}
% The \emph{mathptmx} package retains the \textsf{Computer Modern Sans
% Serif} and \texttt{Computer Modern Teletype} fonts, but they blend
% reasonably well with \emph{Times Roman} (at least in my opinion) so
% I will keep them.
%
% \subsection{Text sizes}
% The specified text sizes are shown in Table\vref{tab:sizes}.
% The leading should be 30\%.
% \begin{table}
% \centering
% \begin{tabular}{cr}
% \Huge \strut\verb:\Huge:& 20\,pt\\

% \begin{macrocode}
\normalsize
% \end{macrocode}
% Since the class uses some non-standard sizes (i.e., not in the
% $1{.}2^n$-series) it must signal \LaTeX{} that font
% scaling may be used.\footnote{These days, all decent \LaTeX{} installations
% should provide scalable fonts.}
% \begin{macrocode}
\RequirePackage{type1cm,type1ec}
% \end{macrocode}
% The class must also define some math sizes.
% \begin{macrocode}
\DeclareMathSizes{11}{11}{8}{6}
\DeclareMathSizes{14}{14}{11}{8}
\DeclareMathSizes{16}{16}{12}{10}
\DeclareMathSizes{20}{20}{14}{12}
% \end{macrocode}
%
%
% \section{Sectioning}
% The section headers in this class have a different look from the
% standard \LaTeX{} classes.
% \begin{macrocode}
\renewcommand{\section}{\@startsection
{section}{1}{0pt}%
{-11pt plus -6pt minus -2pt}%
{11pt plus 6pt minus 2pt}%
{\normalfont\normalsize\bf}}
\renewcommand{\subsection}{\@startsection
{subsection}{2}{0pt}%
{-11pt plus -6pt minus -2pt}%
{11pt plus 6pt minus 2pt}%
{\normalfont\normalsize\it}}
\renewcommand{\subsubsection}{\@startsection
{subsubsection}{3}{0pt}%
{-11pt plus -6pt minus -2pt}%
{11pt plus 6pt minus 2pt}%
{\normalfont\normalsize}}
% \end{macrocode}
% The default definitions of \verb:\paragraph: and
% \verb:\subparagraph: are retained.
%
% \subsection{Section numbering}
% No sections should be numbered.
% \begin{macrocode}
\setcounter{secnumdepth}{-2}
% \end{macrocode}
%
%
% \section{Floats}
% Formating of float captions is best handled using the
% \textsf{caption} package. This style wants them
% \begin{itemize}
% \item indentend 0.5\,cm on each side
% \item 8\,pt type size
% \item numbering should use ``Fig.~1'' or ``Tab.~1''.
% \end{itemize}
% \begin{macrocode}
\RequirePackage[margin=0.5cm,font=footnotesize,
aboveskip=5pt]{caption}
\DeclareCaptionLabelFormat{fig}
{\ifthenelse{\equal{#1}%
{Figure}}{Fig}{Tab}.~#2}
\captionsetup{labelformat=fig}
% \end{macrocode}
% We also adjust the spacing around the floats, and we do not want
% half-empty float-columns.
% \begin{macrocode}
\setlength{\floatsep}{6pt plus 3pt}
\setlength{\textfloatsep}{\floatsep}
\renewcommand{\floatpagefraction}{0.8}
% \end{macrocode}
%
%
% \section{Document reference list}
% The reference list should be according to the Vancouver style:
% \begin{macrocode}
\bibliographystyle{vancouver}
% \end{macrocode}
% but the bibliography should be set in 9\,pt type size with 3\,pt vertical
% space.
% \begin{macrocode}
\renewcommand{\@openbib@code}{\small
\setlength{\itemsep}{3pt}%
\setlength{\parsep}{1pt plus 1pt}}
% \end{macrocode}
% In the bibliography, citations will be indicated as ``1.''
% rather than as ``[1]''.
% \begin{macrocode}
\renewcommand\@biblabel[1]{#1.}
% \end{macrocode}
%
% \Finale
