A finite aspect-ratio configuration is extensively investigated, both quantitatively and qualitatively, in a low-speed wind tunnel. Direct force measurements are made, as well as time-accurate and time-averaged laser Doppler velocimetry and unsteady flow visualization. The reduced frequency, mean angle of attack, aspect ratio and Reynolds number are varied in the experiments. The experiment is numerically simulated using flatplate theory, two and three-dimensional panel codes, and two and three-dimensional Euler and Navier- Stokes solvers. The ability of each of the methods to capture important aspects of the flow physics are evaluated through comparisons with each other and the experimental data. Additionally, the comparisons indicate areas where further research is needed. The collaborative effort provides a survey of available capabilities and provides a fixed set of flappingwing data for others to compare against.}, language = {en} } @incollection{Mohren2003, author = {Mohren, Henning}, title = {Automatische SSL-Zertifizierung}, series = {Security, E-Learning, E-Services}, booktitle = {Security, E-Learning, E-Services}, editor = {von Knop, Jan and Haverkamp, Wilhelm and Jessen, Eike}, publisher = {Gesellschaft f{\"u}r Informatik e.V.}, address = {Bonn}, isbn = {3-88579-373-3}, pages = {233 -- 242}, year = {2003}, abstract = {Die Akzeptanz und Verbreitung von PKI-L{\"o}sungen (Public Key Infrastructure) nimmt in den letzten Jahren zwar zu, ein Durchbruch ist jedoch bisher nicht gelungen.
