Decay Estimates for the Wave Equation with Internal Damping,We obtain optimal estimates for the solution of an integral inequality related to many stabilization problems. Then it is applied to improve some recent results concerning the energy decay of the wave equation with internal nonlinear feedback. Unlike the earlier works, our method also applies in the case of bounded feedback functions.

Damage Detection and Characterization in Smart Material Structures,ion of damage in piezoceramic based smart material structures. The feasibility of using self-exitation/self-sensing with piezoceramics in vibration nondestructive testing is demonstrated using a combination of experimental and simulated data computational tests.

Various Relaxations in Optimal Control of Distributed Parameter Systems,meter systems. An infinite number of relaxed problems and corresponding Pontryagin maximum principles are thus obtained, including those described in the literature. A comparison and an abstract unifying viewpoint is thus made possible.

VOB/B 2016 - Textausgabe/Text Editionristics responsible for variations in growth rates for individuals of the same size is investigated. It is shown that the model can be formulated as an abstract Cauchy problem in an appropriate Banach space. We proof wellposedness of the abstract linear problem and also for a nonlinear perturbation
