Ein effizientes Frequenzmanagement ist essentiell, um dem Bedarf an interferenzfreier Funkkommunikation gerecht zu werden. In diesem Zusammenhang wird das Konzept eines automatischen Spektrum-Monitoring-Systems vorgestellt, welches die lokale spektrale Effizienz ermittelt. Hierzu wird in einem neuartigen Ansatz eine multiple Parameterschätzung zur Funksignalidentifikation realisiert. Zudem werden neue Verfahren in der automatischen Kanalsegmentierung und Modulationsartenerkennung eingeführt. An efficient spectrum management is the key for interference-free wireless communication. The automated spectrum monitoring system presented in this thesis detects and identifies improper use of the RF spectrum. The introduced algorithm can measure the local spectral efficiency and allows a better RF spectrum management in the future. Additionally new algorithms for automated channel segmentation and modulation classification are implemented and evaluated in typical RF monitoring scenarios.

This work proposes a Multibody Structure from Motion (MSfM) algorithm for moving object reconstruction that incorporates instance-aware semantic segmentation and multiple view geometry methods. The MSfM pipeline tracks two-dimensional object shapes on pixel level to determine object specific feature correspondences, in order to reconstruct 3D object shapes as well as 3D object motion trajectories.

A weave reinforced composite material with a thermoplastic matrix is investigated by using a multiscale chain to predict the macroscopic material behavior. A large-strain framework for constitutive modeling with focus on material non-linearities, i.e. plasticity and damage is defined. The ability of the geometric and constitutive models to predict the deformation and failure behavior is demonstrated by means of selected examples.
