Subspace identification methods (SIM) have enjoyed tremenous development in the last 15 years in both theory and practice. IMs offer an attractive alternative to input-output methods due o simple and general parametrization for MIMO systems (there s no linear input-output parametrization that is general enough or all linear MIMO systems, see (Katayama, 2005)). Most SIMs all into the unifying th...

in this paper, an exchange of letters between the philosopher jacques derrida and architect peter eisenman is used as a catalyst to discuss the material qualities of glass and its relationship with the concept of transparency in architecture. in his criticism of an architecture devoid of human qualities, derrida uses glass, defined through walter benjamin’s writings, as a hard and cold material...

A general approach to the dimensional reduction of non-linear nite element models of solid dynamics is presented. For the Newmark implicit time-discretization, the computationally most expensive phase is the repeated solution of the system of linear equations for displacement increments. To deal with this, it is shown how the problem can be formulated in an approximation (Ritz) basis of much sm...
