Each contributor will share their results, which will be compared thanks to the set up of a common database<br>of the computational data and results. In addition, a Round Table assessment of the contributions, with international Senior Technical Experts, will be organized at the end of the Workshop.<br></span></p><div><br></div><p style="margin: 0cm; margin-bottom: .0001pt;" data-mce-style="margin: 0cm; margin-bottom: .0001pt;"><span lang="EN-US"></span>Best regards,<span lang="EN-US"><br></span></p><div><br></div><p style="margin: 0cm; margin-bottom: .0001pt;" data-mce-style="margin: 0cm; margin-bottom: .0001pt;"><span lang="EN-US"></span>PADRI 2017 organizers</p><p class="MsoNormal" style="mso-margin-top-alt: auto; mso-margin-bottom-alt: auto;" data-mce-style="mso-margin-top-alt: auto; mso-margin-bottom-alt: auto;"><span lang="EN-GB"> </span></p><p class="MsoNormal"><span lang="EN-GB"><br><br></span><span style="mso-fareast-language: ES;" data-mce-style="mso-fareast-language: ES;"></span></p></div><div><br></div><style><!--<br><div><br></div>@font-face<br> {font-family:"Cambria Math";<br> panose-1:2 4 5 3 5 4 6 3 2 4;}<br><div><br></div>p.MsoNormal, li.MsoNormal, div.MsoNormal<br> {margin:0cm;<br> margin-bottom:.0001pt;<br> font-size:12.0pt;<br> font-family:"Times New Roman","serif";<br> color:black;<br> mso-fareast-language:EN-US;}<br>a:link, span.MsoHyperlink<br> {mso-style-priority:99;<br> color:blue;<br> text-decoration:underline;}<br>a:visited, span.MsoHyperlinkFollowed<br> {mso-style-priority:99;<br> color:purple;<br> text-decoration:underline;}<br>p<br> {mso-style-priority:99;<br> mso-margin-top-alt:auto;<br> margin-right:0cm;<br> mso-margin-bottom-alt:auto;<br> margin-left:0cm;<br> font-size:12.0pt;<br> font-family:"Times New Roman","serif";<br> color:black;}<br>span.EstiloCorreo18<br> {mso-style-type:personal-reply;<br> font-family:"Calibri","sans-serif";<br> color:#1F497D;}<br>.MsoChpDefault<br> {mso-style-type:export-only;<br> font-size:10.0pt;}<br>@page WordSection1<br> {size:612.0pt 792.0pt;<br> margin:70.85pt 3.0cm 70.85pt 3.0cm;}<br>div.WordSection1<br> {page:WordSection1;}<br>--></style></body></html>
