In this thesis we show how the concept of Pyragas control can be adapted to equivariant dynamical systems near Hopf bifurcation. We introduce a control term which uses the spatio-temporal symmetry of the unstable periodic orbit. We give explicit necessary and sufficient conditions for the stabilization of the periodic orbit near equivariant Hopf bifurcation. For the remaining eigenvalues, we ca...

Design of products permits to yield goods and services to produce satisfaction on customers, which is measured as value. However, it is at this stage in which most of the environmental impact, from a lifecycle perspective, is added to the product. Eco-design aims at increasing value of products while reducing the burdens on the environment by means conscious design towards efficient use of reso...

The validation of software quality metrics lacks statistical significance. One reason for this is that the data collection requires quite some effort. As a help to solve this problem, we develop tools for metrics analysis of a large number of software projects. Moreover, a validation of software quality metrics should focus on relevant metrics, i.e., correlated metrics need not to be validated ...
