In many engineering problems, stability issues are often linked to the theory of dissipative systems which postulates that the energy dissipated inside a dynamical system is less than the energy supplied from an external source. In the literature of nonlinear control, dissipativity concept was initially introduced by Willems in his seminal two-part papers [14, 15] in terms of an inequality invo...

Partial differential-difference equations are the multidimensional generalization of ordinary delay-differential equations. We investigate behaviors of analytic signals governed by equations of this type, i.e., solution modules of linear systems with constant coefficients of such equations, and especially the problems of elimination and duality. The first concerns the question whether the image...

Background Loss of personal dignity in patients with a serious and progressive disease is associated with psychological suffering and loss of the will to live. Preservation of a sense of dignity in the seriously ill should therefore be a primary concern throughout the illness trajectory from diagnosis onward. However, there is currently limited insight into the dynamics of patients' sense of di...

We consider the Gaussian Dirty Tape Channel (DTC) YY = XX + SS + ZZ , where SS is an additive Gaussian interference known causally to the transmitter. The general expression mmmmmmPPUU,ff(∙),XX=ff(UU,SS) II(UU;YY) is presented for the capacity of this channel. For linear assignment to ff(∙) , i.e. XX = UU− ββSS , this expression leads to the compensation strategy proposed previously by Willems ...

Distributed project coordination requires insight in the types of interaction involved in engineering practice. In current practice, well-structured hierarchical management and decentralised project organisation are often combined. Within an organisation, a number of levels can be found within which responsibility for effective interaction is delegated to the engineers themselves. Engineers dec...

indeed has $D=b¥cdot c^{*}$ for $b^{*}=(0,¥ldots,0,1)$ and $c^{*}$ with entries $¥frac{1}{2}(¥beta_{k}-a_{k})$ . (As Jan Willems once pointed out, all the entries are constants; however, the zeros and ones are stiff structure constants, while only the last row has “soft” parameters, to be encompassed by a rank-one control matrix.) Section 1 presents a canonic decomposition of the state space of...

Los planteamientos pedagógicos de Edgar Willems parten una concepción holística la música que persigue no solo formación propiamente musical, sino tanto a nivel afectivo como psicológico los individuos través audición, melodía, el ritmo, las canciones o movimiento. A lo largo sus escritos, centrados esencialmente en iniciación l musicoterapia es un tema recurrente aparece vinculado educativos, ...
