  abstract  = {As a non-contact process laser beam melt ablation offers several advantages compared to conventional processing mechanisms. During ablation the surface of the workpiece is molten by the energy of a CO2-laser beam, this melt is then driven out by the impulse of an additional process gas. Although the idea behind laser beam melt ablation is rather simple, the process itself has a major limitation in practical applications: with increasing ablation rate surface quality of the workpiece processed declines rapidly. With different ablation rates different surface structures can be distinguished, which can be characterised by suitable surface parameters. The corresponding regimes of pattern formation are found in linear and non-linear statistical properties of the recorded process emissions as well. While the ablation rate can be represented in terms of the line-energy, this parameter does not provide sufficient information about the full behaviour of the system. The dynamics of the system is dominated by oscillations due to the laser cycle but includes some periodically driven non-linear processes as well. Upon the basis of the measured time series, a corresponding model is developed. The deeper understanding of the process can be used to develop strategies for a process control.},

  abstract  = {»Wenn du reisen willst, mußt du die Geschichte dieses Landes kennen und lieben. Das ist ganz unerl{\"a}ßlich. [...] Wag' es getrost und du wirst es nicht bereuen. Eigent{\"u}mliche Freuden und Gen{\"u}sse werden dich begleiten. Du wirst Entdeckungen machen, denn {\"u}berall wohin du kommst, wirst du, vom Touristenstandpunkt aus, eintreten wie in ›jungfr{\"a}uliches Land‹. Du wirst Klosterruinen begegnen, von deren Existenz h{\"o}chstens die n{\"a}chste Stadt eine leise Kenntnis hatte; du wirst inmitten alter Dorfkirchen, deren zerbr{\"o}ckelter Schindelturm nur auf Elend deutete, große Wandbilder oder in den treppenlosen Gr{\"u}ften reiche Kupfers{\"a}rge mit Kruzifix und vergoldeten Wappenschildern finden; du wirst Schlachtfelder {\"u}berschreiten, Wendenkirchh{\"o}fe, Heidengr{\"a}ber, von denen die Menschen nichts mehr wissen.« Die in diesem Bildband gesammelten »Denkmalentdeckungen« verstehen sich als Einladung zu einer Reise durch das Land Brandenburg. Theodor Fontane hatte f{\"u}r ein solches Unternehmen genau den richtigen Blick, als er in seinen »Wanderungen durch die Mark Brandenburg« 1864 diese S{\"a}tze schrieb. Auch heute noch sollten wir seiner Anregung zu Begegnungen mit der Geschichte und der Kunstgeschichte des Landes folgen, die uns im Dialog der Kulturen und der Zeiten eine Standortbestimmung in der Gegenwart und eine Orientierung f{\"u}r die Zukunft zugleich bietet.},
