The vision of KU is “To become a world-class university devoted to bringing knowledge and technology to the service of mankind”. Its mission is “To provide quality education for leadership”

The SINTEF Group is the largest independent research organisation in Scandinavia. Every year, SINTEF supports the development of 2000 or so Norwegian and overseas companies via its research and development activity. Its vision is “Technology for a better society”. SINTEF's goal is to contribute to wealth creation and to the sound and sustainable development of society. SINTEF generate new knowledge and solutions for its customers, based on research and development in technology, the natural sciences, medicine and the social sciences.

SINTEF Energy Research is engaged in contract research in the national and international markets. R&D activities are focused on power production as well as energy conversion, transmission, distribution and the use of energy, including industrial processes and products.

The Norwegian Agency for Development Cooperation (Norad) is a directorate under the Norwegian Ministry of Foreign Affairs (MFA).

It aims to be the centre of expertise for evaluation, quality assurance and dissemination of the results of Norwegian development cooperation, jointly with partners in Norway, developing countries and the international community It will ensure that the goals of Norway's development policy are achieved by providing advice and support to the Ministry of Foreign Affairs and Norwegian foreign service missions. It will administer the agency's grant schemes so that development assistance provided through Norwegian and international partners contribute effectively to poverty reduction.

These goals will be achieved on the foundation of Norad's current competencies, through highly qualified staff, a flexible and practical organisation, good administrative support functions and a working environment characterised by transparency, respect, equality, responsibility and quality.
