GarciaPL Notes - Java and Others

I was recently searching for my thesis a information in which way it is possible to get MS (Mobile Station) location in GSM Network. Below i will present an AnyTime Interrogation (ATI) message, which is transmitted by Service Control Point (SCP) to HLR (Home Location Reqister) for requesting MS location information. After that HLR return a query to appropriate MSC to perform VLR look-up.

In this post i will put some very quick tips how create bold, italic and underline text in LaTeX.

Bold

             \textbf{simple text} or \bf{simple text}

             \textit{simple text} or \it{simple text}

Underline

             \underline{simple text} or \emph{simple text}

A quik and small tip in Perl which may sound funny, but it saved my life :D

if ( -d "/folder/path/" ) {
         print "Success! Directory exists!\n";
} else {
         print "Sad news... It is gone!\n";
}
