Here is an Open Access Problem
NDT.net has permission from the publisher (European Commission Joint Research Centre) to publish this conference series. Unfortunately the EC-JRC does not ask authors for third party permission, so we have to ask
each author for permission individually. That is a lot of bureaucracy and it is not possible to get in contact with all authors. At each conference they have held we have requested the EC-JRC (three committee members USA, EC, Japan) to change this procedure, so far without any success. We still hope that this policy will change to make Open Access practical.
We contacted all authors from which we have their email address for their permission to publish their papers. If you are an author of a paper and you did not receive our email please send email to Rolf Diederichs at firstname.lastname@example.org and give permission for your paper.
We hope you will make your article Open Access available to the public.
