Object-Tokens in High-Level Grafchart

The paper presents an high-level extension to Grafchart, a Grafcet-based toolbox for supervisory control applications. The extension allows tokens to be objects with attributes. Contrary to most high-level extensions to Petri Nets and Gracet it is not based on inscriptions.

Dinuclear metal complexes modelling active sites of metallohydrolases

To study the active sites of dinuclear metallohydrolases new metal complexes that model these sites both in structure and function have been synthesized using two new phenol based dinucleating ligands, 2-(N-isopropyl-N-((2-pyridyl)methyl)aminomethyl)-6-(N-(carboxylmethyl)-N-((2-pyridyl)methyl)aminomethyl)-4-methylphenol (IPCPMP) and 2,6-Bis[N-(N-(carboxymethyl)-N-(pyridylmethyl)amine)methyl]-4-met

A Toolbox for Computational Analysis of Piecewise Linear Systems

This paper reports the development of a Matlab toolbox for computational analysis of piecewise linear systems. The analysis is based on piecewise quadratic Lyapunov functions, which are computed via convex optimization. In this way, exponential stability and system performance can be assessed. The toolbox also supports efficient simulation of systems with discontinuous dynamics and sliding modes.
