    Mulder, T.A.C.
    This thesis is concerned with the notion of Darwinism and its application outside of its traditional biological realm, to that of economics. The mechanism of natural selection is based on the co-­‐ existence of variational, hereditary and selective processes within a system (Cordes 2006). This context-­‐independent description of natural selection has been coined ‘Universal Darwinism’, the extent and practical relevance of which is not thoroughly understood. This thesis has aimed to co....................

    (2012-06-15) Advanced Flight Control Design and Evaluation: An application of time delayed Incremental Backstepping:
    Koschorke, J.F.R.
    The sensor-based approach of Incremental Backstepping is applied to flight control law design in this research project. It allows the usage of the same control law on different types of aircraft without the need for redesign. Apart from full state availability, the derivation of Incremental Backstepping assumes instantaneous control action. Due to actuator lags and delays, the implementation of control commands cannot necessarily be considered instantaneous. This mitigates the stability guaran....................
