A closed-loop system identi cation toolbox for Matlab is presented, including a user-friendly graphical user interface, that communicates with MathWork's System Identi cation Toolbox (SITB), version 4.0. With the CLOSID toolbox it is possible to identify linear (parametric) models on the basis of experimental data obtained from a plant that is operating under the presence of a controller. The t...

We address the conjecture that at the tachyonic vacuum open strings get transformed into closed strings. We show that it is possible in the context of boundary string field theory to interpolate between the conventional open string theory, characterized by having the D25 brane as the boundary state, and an off-shell (open) string theory where the boundary state is identified with the closed str...

The effect of the solid-state environment for an Mn cation in MnO on the Mn 2pand 3p-shell x-ray photoemission spectra XPS has been investigated using ab initio relativistic wave functions for an embedded MnO6 cluster model of MnO. These wave functions include many-body effects due to the angular momentum coupling and recoupling of the open-shell electrons. They also include the covalent mixing...

The 3 centre-4 electrons (3c-4e) and the donor/acceptor or charge-transfer models for the description of the chemical bond in linear three-body systems, such as I(3) (-) and related electron-rich (22 shell electrons) systems, are comparatively discussed on the grounds of structural data from a search of the Cambridge Structural Database (CSD). Both models account for a total bond order of 1 in ...
