How to reduce space between lines in a table

Sometimes (horizontal) space is jut too much in a LaTeX table.
In order to decrease it, it is actually possible to give negative values to addlinespce

\begin{tabular}{ll}

   Line1&some text\\

    \addlinespace[-0.3ex]

             Line1&some text\\

\end{tabular}

Making list / glossary of acronyms and abbreviations

The easiest way to write abbreviations is to make use of the acronym package, see
http://latexbestpractice.blogspot.pt/2013/08/writing-acronyms-and-abbreviations-in.html

To define the glossary (list of abbreviations), I define acronyms using
\acro{short}[short-to-appear]{full-definition} command. Then referring the abbreviations with \ac command. Note \acf, is for full description, even if it's not the first occurrence, and \acs for plural form.

\usepackage{acronym}

...

\subsection*{Abbreviations}
\begin{acronym}
    \acro{mse}[MSE]{Mean Squared Error}
    \acro{mmse}[MMSE]{Minimum Mean Squared Error}
    \acro{}[ODE]{Ordinary Differential Equation}
\end{acronym}

...
\ac{ode} ...
\ac{mse} ....
\acf{ode}

How to prevent figures and tables from floating

Many times I received messages like

  LaTeX Warning: `!h' float specifier changed to `!ht'.

resulting my figures / tables appearing on the top of the page, however I wanted to place the figure _exactly_ where at that position.

TThe solution I found here is to use the package float

\usepackage{float}
...
\begin{figure}[H]
...
\end{figure}
