Port-based network modeling of (lumped-parameter) physical systems leads directly to their representation as port-Hamiltonian systems which are an important class of passive state-space systems. At the same time modeling of physical systems often leads to high-dimensional dy namical models. State-space dimensions are enormously high as well if distributed-parameter models are spatially discreti...

Benveniste’s experiments have been the subject of an international scientific controversy (known as the case of the “memory of water”). We recently proposed to describe these results in a modeling in which the outcome of an experiment is considered personal property (named cognitive state) of the observer and not an objective property of the observed system. As a consequence, the correlations b...

underlying mathematics is rather complicated. As a consequence, modern system identification methods are often not used even if their use is otherwise justified. The complicated structure of validity conditions and the many alternatives and possibilities keep many of us away. Moreover, because the use of advanced system identification methods often requires a lot of programming work, the attent...

An Interorganizational Business Process (IOBP) is an organized group of related activities carried out by multiple organizations to accomplish a common business goal. A consequence of this is that business process modeling and design used inside an organization have to be enhanced and extended to cope with interorganizational business relationships. Modeling business processes that span multipl...

Meta-modeling is a well-known approach for capturing modeling methods and techniques. A meta-model can serve as a basis for quantitative evaluation of methods and techniques. By means of a number of formal metrics based on the meta-model, a quantitative evaluation of methods and techniques becomes possible. Existing meta-modeling languages and measurement schemes do not allow the explicit model...

Research on quality issues of business process models has recently begun to explore the process of creating process models. With growing complexity, the creation of business process models requires the presence of several, potentially spatially distributed stakeholders. As a consequence, the question arises how this affects the process of process modeling. This paper describes a thesis working ...

Over the last decades, renewable energy sources have increased considerably their generation share in power systems. As a consequence, terms of frequency deviations, both grid reliability and stability raised interest. By considering absence consensual set models for control analysis, different units (conventional renewables) system itself, this paper provides extensive significant information ...
