Research profiles are captured using the following six indicators:

• Professors,
• Non-professorial scientific staff,
• Basic funding,
• Third-party / grant funding,
• Web of Science publications,
• Web of Science citations.

These six indicators are presented for the technical universities (TU) and for the non-technical universities (NTU). Each university is compared within its respective group (TU, NTU). The focus is on two specialization indices (RESP and RSI). They are calculated based on the activity index (AI) (here using the example of professors):

$$ AI_{ij} := \frac{\text{professors at university } i \text{ in field } j / \text{ professors in field } j}{\text{professors at university } i / \text{ all professors}} $$

\begin{align} \text{Relative Specialization } (RESP) :=&\; 100\, \frac{AI^2 - 1}{AI^2 +1}\\ & \\ \text{Relative Specialization Index } (RSI) :=&\; 100\, \frac{AI - 1}{AI +1} \end{align}
