In this contribution a recently proposed model reduction method for a class of linear time-invariant (LTI) parameterized models is investigated. The method is based on matching of the frequency response samples using the semidefinite programming methods. The main focus of this contribution is the properties of the obtained approximations. Among those properties is stability of individual LTI syste
Supply chains are difficult to plan because they involve complex relationships that influence supply chain performance. In this paper, discrete-event simulation (DES) is discussed in order to identify if it could be a technique used to improve supply chain planning. Two DES models have been developed and are used in this paper to find out whether DES could be a technique for unraveling the complex
The need for integrated management of urban wastewater systems (UWS) is highly acknowledged in both research and industry. Modelling studies and practical experiences with integrated control of UWS clearly suggest the benefits of a holistic control approach. Given the success of benchmark simulation models (BSMs) in the study of control strategy options for wastewater treatment plants (WWTPs), a s
This paper analyzes Danish reactions to the Muhammad cartoon caricature crisis, emphasizing the three narratives that dominate the discussion following the protests against the publication of the 12 cartoons in the Danish newspaper Jyllandsposten. The narratives were: freedom of speech versus intimidation by Muslims; harrasment of Muslims; and as a sign of failed integration of Muslims into Danish
