Michel C. Delfourert sich. Einige Länder verändern die staatliche Regulierung des Sektors, weil sie der Auffassung sind, die alten Regeln und Strukturen werden den neuen Herausforderungen nicht mehr gerecht. Großbritannien ist ein Beispiel dafür. Ein Aspekt dieses Strukturwandels ist die Einheit bzw. die Trennung vo

Exponential Bases in Sobolev Spaces in Control and Observation Problems,e present examples of such systems, specifically those for which we can prove that the related exponential families form a Riesz basis in corresponding appropriately defined Sobolev spaces. This makes it possible to choose ‘natural’ pairs of spaces: the state space / observability space and the cont

Sampling and Interpolation of Functions with Multi-Band Spectra and Controllability Problems,sampling and interpolating set for the space of functions with limited multi-band spectra to a controllability problem for a model dynamical system. As a model we consider the wave equation with piecewise constant density and boundary control supported on the same union of intervals. For the case of

,Intrinsic , (2, 1) Thin Shell Model and Naghdi’s Models without A Priori Assumption on the Stress Tts potential has been illustrated by investigating some linear models of thin shells based on truncated series expansions with respect to the variable normal to the midsurface. In this paper we characterize the solution space of the .(2, 1) model for an arbitrary constitutive law and a midsurface wi
