I need to find "Algorithms for Polynomials Over a Real Algebraic Number Field
Ph.D. thesis, University of Wisconsin, Madison (1974) by Rubald". However I cannot find it online nor in my university library, even though it seems to be quite a popular reference in the field (eg. Collins and McCallum often cite it).

I'm especially interested in the efficient algorithms for the arithmetic operations in the field $\mathbb{Q}(\alpha)$.



Algorithms for Polynomials Over a Real Algebraic Number Field, a reference
The thesis can be found [here](https://ftp.cs.wisc.edu/pub/techreports/1974/TR206.pdf).
