Sommario/riassunto |

The theory of linear damped oscillations was originally developed more than hundred years ago and is still of vital research interest to engineers, mathematicians and physicists alike. This theory plays a central role in explaining the stability of mechanical structures in civil |

engineering, but it also has applications in other fields such as electrical network systems and quantum mechanics. This volume gives an introduction to linear finite dimensional damped systems as they are viewed by an applied mathematician. After a short overview of the physical principles leading to the linear system model, a largely self-contained mathematical theory for this model is presented. This includes the geometry of the underlying indefinite metric space, spectral theory of J-symmetric matrices and the associated quadratic eigenvalue problem. Particular attention is paid to the sensitivity issues which influence numerical computations. Finally, several recent research developments are included, e.g. Lyapunov stability and the perturbation of the time evolution. |

Sommario/riassunto |
|
This collection of articles aims to stimulate the exploration of African initiative and creativity and to go beyond immediate socio-economic and political circumstances by analyzing those initiatives that offer alternatives to the prevailing paradigms. It moves away from African ‘victimhood’ by stressing African ‘agency’ and by demonstrating that societies in Africa have always showed the ability to negotiate whatever constraining ecological, economic and political circumstances they faced. This is further detailed in the context of the literary contest between local and global; of issues of land rights and property; of livelihoods and poverty; of the popular culture; of demystifying African migrations; the changing parameters of territoriality; and the dynamics of the tourist encounter. |
