My Candidatus Scientiarum (Cand.Scient.) thesis, delivered in June 1993 at Bergen University: "Tensor Fields, from specification to implementation" (sorry, Norwegian only). Tensor Fields are used in almost all parts of scientific computing, like weather forecasting, fluid flow (e.g. reservoir simulations) and wave propagation. Newer scientific fields (like Machine Learning, Computer Vision and Artificial Intelligence) also make extensive use of Tensor fields.
