The stability properties of a fairly general continuous-time adaptive control scheme are analyzed. Sufficient conditions for $L^\infty $-stability in the presence of disturbances are given. The stability results are used to prove convergence of the process outputs in the disturbance-free case, without requiring any a priori stability assumptions.
My research is about the possibility of understanding and interpreting artworks by Joseph Beuys (1921-1986) in a broader sense than is usually done before: I want to start with some actions, follow different action-tools from these, into the vitrines of the art museums. In my performative analysis there are no fixed boundaries between Beuys himself as an actor in his actions, his artworks, that is
A method is presented for assessing disturbances in SISO loops.The method indicates if the SISO loop under consideration will benefit from an addition of feed forward control from a measured disturbance. The method uses minimal process knowledge and is based on measurement from normal operation.
This report includes a description of a newly developed simulation tool for energy mapping of different paper drying processes. The simulation tool includes models for three different types of paper dryers and for a coating station and various units used for heat recovery. The models were developed in the block oriented simulation program Extend. The Extend software is briefly described and the eq
Call the Dependence Thesis the popular view that values are dependent on emotions. This paper argues that the Dependence Thesis is amenable to different readings and critiques one particular reading. According to the Definitional Dependence Thesis, definitions of evaluative concepts necessarily have to appeal to emotions. By contrast, according to the Epistemic Dependence Thesis, which is the targ

To determine whether normal adults of good and poor reading ability exhibit different patterns of sensitivity to spatial frequency, as previously found between dyslexic and nondyslexic control subjects. methods. The visual acuity, spatial frequency sensitivity, and reading ability of 96 normal, nondyslexic adults was assessed. Participants were ranked according to reading ability. The to
