Towards reasonability properties for access-control policy languages
The growing importance of access control has led to the definition of numerous languages for specifying policies. Since these languages are based on different foundations, langua...

An error bound for model reduction of Lur'e-type systems
— In general, existing model reduction techniques for stable nonlinear systems lack a guarantee on stability of the reduced-order model, as well as an error bound. In this paper,...

Input design using Markov chains for system identification
This paper studies the input design problem for system identification where time domain constraints have to be considered. A finite Markov chain is used to model the input of the s...
