A comprehensive overview of the principles and applications of femtosecond lasers, especially applied to medicine and to production technology. The advantages and problems of ultrashort laser pulses are discussed in more detail in the context of applications in the micro-machining of technical materials such as drilling, surface structuring and cutting, in medical use like dental, ophthalmologic, neurological and otolaryngological applications, in metrology, and in the generation of x-rays. Safety aspects are also considered.
The main goal of this thesis was to extend and apply time resolved x-ray scattering experiments at in-house, synchrotron and free electron laser sources to soft matter sample systems, in particular aligned lipid multilayers on solid support. A special emphasis was placed on a characterization of the non-equilibrium fast time response of the multilamellar stack to shortly pulsed optical excitation as well as the acousto-electric field accompanying a surface acoustic wave (SAW). In addition to fundamental questions associated with non-equilibrium dynamics of soft matter films such as driven membrane undulations, this thesis addresses technological challenges of time resolved x-ray diffraction, in particular concerning the timing scheme that has been implemented at the synchrotron storage ring Petra III, DESY, Hamburg. Importantly, a conceptually new pulse resolved x-ray detection scheme, well exceeding the performance of present detector concepts, has been developed and is described in detail.
Highlights und Innovationen aus der Fertigungstechnik mit Lasern führten vom 28. bis 30. September 2005 zum vierten Mal Laserexperten und Anwender in Stuttgart zusammen. Namhafte Vertreter aus Industrie und Wissenschaft haben beispielhafte Entwicklungen und neue Trends im industriellen Einsatz der Lasertechnik in unterschiedlichen Branchen wie dem Automobilbau, Maschinenbau und der Elektrotechnik aufgezeigt. Der fachliche Schwerpunkt lag in diesem Jahr auf dem Gebiet der Absicherung von Fertigungsverfahren.
Dass regenerativ betriebene Inselsysteme mit Speichern unter bestimmten Voraussetzungen wirtschaftlich sind, zeigt die hier vorgestellte Methode zur Auslegung von regenerativ betriebenen Versorgungssystemen als Inselnetz unter Verwendung von Energiespeichern auf der Basis von statistischen Modellen. Das Versorgungssystem wurde mithilfe von Kostenmodellen und mittels Optimierungssoftware ausgelegt. Die Validierung wurde anhand von Messungen aus zwei realen Versorgungsgebieten vorgenommen. - The proposed method for the configuration of renewably powered energy supply systems as isolated grids backed by energy storage technology and based on statistical models shows the economic viability of such a system. The energy supply system was configured by implementing cost models using an optimization software. Validation was achieved through comparison with measurements taken from two different existing energy supply areas.

INTERACT 2009 was the 12th of a series of INTERACT international c- ferences supported by the IFIP Technical Committee 13 on Human–Computer Interaction. This year,INTERACT washeld in Uppsala (Sweden), organizedby the Swedish Interdisciplinary Interest Group for Human–Computer Interaction (STIMDI) in cooperation with the Department of Information Technology at Uppsala University. Like its predecessors, INTERACT 2009 highlighted, both to the academic and to the industrial world, the importance of the human–computer interaction (HCI) area and its most recent breakthroughs on current applications. Both - perienced HCI researchers and professionals, as well as newcomers to the HCI ?eld, int...
