About CentOS:

The Community ENTerprise Operating System (CentOS) Linux is a community-supported enterprise distribution derived from sources freely provided to the public by Red Hat. As such, CentOS Linux aims to be functionally compatible with Red Hat Enterprise Linux. The CentOS Project is the organization that builds CentOS. We mainly change packages to remove upstream vendor branding and artwork.

For information on CentOS please visit the CentOS website.


CentOS is an Operating System and it is used to power this website; however, the webserver is owned by the domain owner and not the CentOS Project. If you have issues with the content of this site, contact the owner of the domain, not the CentOS Project.

Unless this server is on the domain, the CentOS Project doesn't have anything to do with the content on this webserver or any e-mails that directed you to this site.

Case Study: Leveraging Organizational Expertise

Abstract: The case study has been undertaken in a research and service organization to examine its expertise within the domain of acquisition of EU fundings for research projects. This domain of knowledge was differentiated into five sub-domains that are important for success or failure of the acquisition of EU funding. This case study was undertaken as a small part of the project “Wachstum mit Wissen” (economic growth through knowledge), sponsored by the German Federal Ministry of Education and Research (BMBF), at the Fraunhofer Institute for Production Systems and Design Technology (Fraunhofer IPK), Berlin, in co-operation with the author at the Department of Information Science, Freie Universität Berlin. Names have been changed at the request of the company; selected visualizations have been simplified for presentation. Read more…
