Our work investigates the application of source camera identification on mobile phones. We present a dataset entirely collected by mobile phones. The dataset contains both still images and videos collected by 67 different smartphones. Part of the images consists in photos of uniform backgrounds, especially collected for the computation of the RSPN. Identifying the source camera given a video is particularly challenging due to the strong video compression. The experiments reported in this paper, show the large variation in performance when testing an highly accurate technique on still images and videos.}, language = {en} } @article{BartellaKamalScholletal.2019, author = {Bartella, Alexander K. and Kamal, Mohammad and Scholl, Ingrid and Schiffer, Stefan and Steegmann, Julius and Ketelsen, Dominik and H{\"o}lzle, Frank W. and Lethaus, Bernd}, title = {Virtual reality in preoperative imaging in maxillofacial surgery: implementation of "the next level"?}, series = {British Journal of Oral and Maxillofacial Surgery}, volume = {57}, journal = {British Journal of Oral and Maxillofacial Surgery}, number = {7}, publisher = {Elsevier}, address = {Amsterdam}, issn = {0266-4356}, doi = {10.1016/j.bjoms.2019.02.014}, pages = {644 -- 648}, year = {2019}, language = {en} } @article{ThielemannSchaffner1996, author = {Thielemann, Frank and Schaffner, M.}, title = {Vom Einzelk{\"a}mpfertum zum kooperativen Kundenservice}, series = {Polygraph. 49 (1996), H. 23-24}, journal = {Polygraph. 49 (1996), H. 23-24}, isbn = {0032-3842}, pages = {40 -- 42}, year = {1996}, language = {de} } @book{ThielemannStaudt1996, author = {Thielemann, Frank and Staudt, Erich}, title = {Von der Druckindustrie zum Multimedia-Dienstleister : Kompetenz durch Innovation / Erich Staudt ; Thielemann, Frank}, publisher = {Inst. f{\"u}r Angewandte Innovationsforschung e.V.}, address = {Bochum}, pages = {40 S.:graph.

A wind-tunnel study of a wing-embedded lifting fan has been conducted at the Side Wind Test Facility G{\"o}ttingen of DLR, German Aerospace Center in G{\"o}ttingen using force, pressure, and stereoscopic particle image velocimetry techniques. The study showed that a step on the lower side of the wing in front of the lifting fan duct increases the lift-to-drag ratio of the whole model by up to 25\% for all positive angles of attack. Different sizes and inclinations of the step had limited influence on the surface pressure distribution. The data indicate that these parameters can be optimized to maximize the lift-to-drag ratio. A doubling of the curvature radius of the lifting fan duct inlet lip on the upper side of the wing affected the lift-to-drag ratio by less than 1\%. The lifting fan duct inlet curvature can therefore be optimized to maximize the vertical fan thrust of the rotating lifting fan during hovering without affecting the cruise flight performance with a nonrotating fan.}, language = {en} } @incollection{BensbergCzarneckiGrob2022, author = {Bensberg, Frank and Czarnecki, Christian and Grob, Heinz Lothar}, title = {Wirtschaftlichkeitsbewertung von Smart Services mit vollst{\"a}ndigen Finanzpl{\"a}nen}, series = {Smart Services: Band 1: Konzepte - Methoden - Prozesse}, booktitle = {Smart Services: Band 1: Konzepte - Methoden - Prozesse}, editor = {Bruhn, Manfred and Hadwich, Karsten}, publisher = {Springer Gabler}, address = {Wiesbaden}, isbn = {978-3-658-37344-3 (Online)}, doi = {10.1007/978-3-658-37344-3_6}, pages = {225 -- 251}, year = {2022}, abstract = {Dieser Beitrag stellt einen Bewertungsrahmen f{\"u}r Smart Services vor, der auf dem Konzept vollst{\"a}ndiger Finanzpl{\"a}ne (VOFI) basiert.
