Aachener Softwaretag in der Wasserwirtschaft <2, 2009, Aachen> Zusammenfassung [der Autoren] F{\"u}r das st{\"a}dtisch gepr{\"a}gte Einzugsgebiet des Broicher Baches sind ein vereinfachter und ein detaillierter Nachweis nach BWK-M3 durchgef{\"u}hrt worden. Dabei zeigt sich, dass die Methodik des vereinfachten Nachweises nicht geeignet ist, um eine realit{\"a}tsnahe Abbildung der einleitungsgepr{\"a}gten Abfl{\"u}sse des Gew{\"a}ssers zu erhalten. Dies ist insbesondere auf die Vernachl{\"a}ssigung von Wellentranslation und -retention im Gerinne zur{\"u}ckzuf{\"u}hren. Die dadurch entstehende Fehleinsch{\"a}tzung der Abflussverh{\"a}ltnisse versperrt den Blick auf eine situationsgerechte Maßnahmenplanung. Der mit Hilfe eines NA-Modells gef{\"u}hrte detaillierte Nachweis ist zwar in der Erstellung aufw{\"a}ndiger, zeichnet aber ein reales Bild der Abflusserh{\"o}hung durch Einleitungen. Mit Hilfe des Modells k{\"o}nnen die wesentlichen Einfl{\"u}sse schnell lokalisiert und zielf{\"u}hrende Maßnahmenvarianten identifiziert werden. In dem hier vorgestellten Beispiel des Broicher Baches k{\"o}nnen die urspr{\"u}nglich identifizierten acht Maßnahmen auf eine reduziert werden. Das Gesamtvolumen der erforderlichen R{\"u}ckhaltungen wird um die H{\"a}lfte verringert. Der Vergleich beider Nachweismethoden legt nach Ansicht der Autoren nahe, den vereinfachten Nachweis h{\"o}chstens f{\"u}r eine erste Einsch{\"a}tzung des Maßnahmenbedarfs anzuwenden. Die Maßnahmenidentifikation und -dimensionierung sollte grunds{\"a}tzlich mit der detaillierten Nachweismethode durchgef{\"u}hrt werden, die auf einem entsprechenden NA-Modell basiert. Dies gilt insbesondere f{\"u}r Gew{\"a}sserstrecken, deren Abfluss durch mehrere, hintereinander liegende Einleitungsstellen gepr{\"a}gt ist.}, subject = {Fließgew{\"a}sser}, language = {de} } @inproceedings{DachwaldWurm2009, author = {Dachwald, Bernd and Wurm, P.}, title = {Mission analysis for an advanced solar photon thruster}, series = {60th International Astronautical Congress 2009, IAC 2009}, volume = {8}, booktitle = {60th International Astronautical Congress 2009, IAC 2009}, publisher = {Elsevier}, address = {Amsterdam}, isbn = {978-161567908-9}, pages = {6838 -- 6851}, year = {2009}, abstract = {The so-called "compound solar sail", also known as "Solar Photon Thruster" (SPT), is a solar sail design concept, for which the two basic functions of the solar sail, namely light collection and thrust direction, are uncoupled. In this paper, we introduce a novel SPT concept, termed the Advanced Solar Photon Thruster (ASPT). This model does not suffer from the simplified assumptions that have been made for the analysis of compound solar sails in previous studies. We present the equations that describe the force, which acts on the ASPT. After a detailed design analysis, the performance of the ASPT with respect to the conventional flat solar sail (FSS) is investigated for three interplanetary mission scenarios: An Earth-Venus rendezvous, where the solar sail has to spiral towards the Sun, an Earth-Mars rendezvous, where the solar sail has to spiral away from the Sun, and an Earth-NEA rendezvous (to near-Earth asteroid 1996FG3), where a large orbital eccentricity change is required. The investigated solar sails have realistic near-term characteristic accelerations between 0.1 and 0.2mm/s2. Our results show that a SPT is not superior to the flat solar sail unless very idealistic assumptions are made.}, language = {en} } @inproceedings{DachwaldOhndorfSpurmannetal.2009, author = {Dachwald, Bernd and Ohndorf, Andreas and Spurmann, J. and Loeb, H.

In this paper, we describe an optimized mission design for a TANDEM-derived solar electric propulsion (SEP) mission. We have chosen the SEP mission scenario for the interplanetary transfer of the TANDEM spacecraft because all feasible gravity assist sequences for a chemical transfer between 2015 and 2025 result in long flight times of about nine years. Our SEP system is based on the German RIT ion engine. For our optimized mission design, we have extensively explored the SEP parameter space (specific impulse, thrust level, power level) and have calculated an optimal interplanetary trajectory for each setting. In contrast to the original TANDEM mission concept, which intends to use two launch vehicles and an all-chemical transfer, our SEP mission design requires only a single Ariane 5 ECA launch for the same payload mass. Without gravity assist, it yields a faster and more flexible transfer with a fight time of less than seven years, and an increased payload ratio. Our mission design proves thereby the capability of SEP even for missions into the outer solar system.}, language = {en} } @article{Grap2009, author = {Grap, Rolf Dietmar}, title = {Mit Ingenieuren und Betriebswirten gemeinsam zum Industrial Engineer}, series = {Industrial engineering : Fachzeitschrift des REFA-Bundesverbandes. 62 (2009), H. 2}, journal = {Industrial engineering : Fachzeitschrift des REFA-Bundesverbandes. 62 (2009), H. 2}, isbn = {1866-2269}, pages = {10 -- 12}, year = {2009}, language = {de} } @misc{BergBesslerGerlachetal.2009, author = {Berg, Gabriele and Bessler, Cornelius and Gerlach, Jochen and G{\"u}bitz, Georg and Heumann, Sonja and Karl, Wolfgang and Maurer, Karl-Heinz and Remler, Peter and Ribitsch, Doris and Schwab, Helmut and Siegert, Petra and Wieland, Susanne}, title = {Mittel enthaltend Proteasen aus Stenotrophomonas maltophilia [Offenlegungsschrift]}, publisher = {Deutsches Patent- und Markenamt / Europ{\"a}isches Patentamt / USPTO / WIPO}, address = {M{\"u}nchen / Den Hague / Washington / Genf}, pages = {1 -- 47}, year = {2009}, language = {de} } @article{BehbahaniTranWalugaetal.2009, author = {Behbahani, Mehdi and Tran, L. and Waluga, C. and Behr, M. and Oedekoven, B. and Mottaghy, K.}, title = {Model-based Numerical Analysis of Platelet Adhesion, Thrombus Growth and Aggregation for Assist Devices}, series = {The International Journal of Artificial Organs. 32 (2009), H. 7}, journal = {The International Journal of Artificial Organs. 32 (2009), H. 7}, isbn = {0391-3988}, pages = {398 -- 398}, year = {2009}, language = {en} } @article{BehbahaniWalugaStocketal.2009, author = {Behbahani, Mehdi and Waluga, C. and Stock, S. and Mai, A. and Bergmann, B. and Behr, M. and Tran, L. and Vonderstein, K. and Scheidt, H. and Oedekoven, B. and Mottaghy, K.}, title = {Modelling and Numerical Analysis of Platelet Reactions and Surface Thrombus Growth}, year = {2009}, language = {en} }
