Ni-Al-Superlegierungen sind bekannt für ihre guten mechanischen Eigenschaften unter hohen Temperaturen. Die elektrochemische Abscheidung von Ni mit Al-Nanopartikeln in LIGA-Strukturen und folgender Wärmebehandlung bietet die Möglichkeit, Ni-Al Superlegierungen für Hochtemperatur-LIGA-MEMS nutzbar zu machen. Über LIGA abgeschiedene Ni-Al-Mikrozugprüfkörper zeigen in Mikrozug- sowie Mikrokriechversuche eine verbesserte thermische Stabilität gegen plastische Verformung.

Unmanned Aerial Vehicles (UAVs) equipped with video cameras are a flexible support to ensure civil and military safety and security. In this thesis, a video processing chain is presented for moving object detection in aerial video surveillance. A Track-Before-Detect (TBD) algorithm is applied to detect motion that is independent of the camera motion. Novel robust and fast object detection and segmentation approaches improve the baseline TBD and outperform current state-of-the-art methods.

Human visual perception is limited to the visual-optical spectrum. Machine vision is not. Cameras sensitive to the different infrared spectra can enhance the abilities of autonomous systems and visually perceive the environment in a holistic way. Relevant scene content can be made visible especially in situations, where sensors of other modalities face issues like a visual-optical camera that needs a source of illumination. As a consequence, not only human mistakes can be avoided by increasing the level of automation, but also machine-induced errors can be reduced that, for example, could...
