Unfortunately, the convergence of traditional trajectory optimizers that are based on numerical optimal control methods depends strongly on an adequate initial guess for the control function (if a direct method is used) or for the starting values of the adjoint vector (if an indirect method is used). Especially when many revolutions around the sun are re- quired, trajectory optimization becomes a very difficult and time-consuming task that involves a lot of experience and expert knowledge in astrodynamics and optimal control theory, because an adequate initial guess is extremely hard to find. Evolutionary neurocontrol (ENC) was proposed as a smart method for low-thrust trajectory optimization that fuses artificial neural networks and evolutionary algorithms to so-called evolutionary neurocontrollers (ENCs) [1]. Inspired by natural archetypes, ENC attacks the trajectoryoptimization problem from the perspective of artificial intelligence and machine learning, a perspective that is quite different from that of optimal control theory. Within the context of ENC, a trajectory is regarded as the result of a spacecraft steering strategy that maps permanently the actual spacecraft state and the actual target state onto the actual spacecraft control vector. This way, the problem of searching the optimal spacecraft trajectory is equivalent to the problem of searching (or "learning") the optimal spacecraft steering strategy. An artificial neural network is used to implement such a spacecraft steering strategy. It can be regarded as a parameterized function (the network function) that is defined by the internal network parameters. Therefore, each distinct set of network parameters defines a different network function and thus a different steering strategy. The problem of searching the optimal steering strategy is now equivalent to the problem of searching the optimal set of network parameters. Evolutionary algorithms that work on a population of (artificial) chromosomes are used to find the optimal network parameters, because the parameters can be easily mapped onto a chromosome. The trajectory optimization problem is solved when the optimal chromosome is found. A comparison of solar sail trajectories that have been published by others [2, 3, 4, 5] with ENC-trajectories has shown that ENCs can be successfully applied for near-globally optimal spacecraft control [1, 6] and that they are able to find trajectories that are closer to the (unknown) global optimum, because they explore the trajectory search space more exhaustively than a human expert can do. The obtained trajectories are fairly accurate with respect to the terminal constraint. If a more accurate trajectory is required, the ENC-solution can be used as an initial guess for a local trajectory optimization method. Using ENC, low-thrust trajectories can be optimized without an initial guess and without expert attendance. Here, new results for nuclear electric spacecraft and for solar sail spacecraft are presented and it will be shown that ENCs find very good trajectories even for very difficult problems.

Especially in expansion nozzles of rocket engines with large area ratio, flow separation can trigger strong side loads that can damage the structure of the nozzle. The investigation presented in this paper seeks to establish measures that may be applied to alter the point of flow separation. In order to achieve this, a supersonic nozzle was placed at the exit plane of the conical nozzle. This resulted in the generation of cross flow surrounding the core jet flow from the conical nozzle. Due to the entrainment of the gas stream from the conical nozzle the pressure in its exit plane was found to be lower than that of the ambient. A Cold gas instead of hot combustion gases was used as the working fluid. A mathematical simulation of the concept was validated by experiment. Measurements confirmed the simulation results that due to the introduction of a second nozzle the pressure in the separated region of the conical nozzle was significantly reduced. It was also established that the boundary layer separation inside the conical nozzle was delayed thus allowing an increased degree of overexpansion. The condition established by the pressure measurements was also demonstrated qualitatively using transparent nozzle configurations.}, language = {en} } @article{Mayer2007, author = {Mayer, Claudia}, title = {Internet statt Zeitung?

Apophis will have a close Earth-encounter in 2029 with potential very close subsequent Earth-encounters (or even an impact) in 2036 or later, depending on whether it passes through one of several less than 1 km-sized gravitational keyholes during its 2029-encounter. A pre-2029 kinetic impact is a very favorable option to nudge the asteroid out of a keyhole. The highest impact velocity and thus deflection can be achieved from a trajectory that is retrograde to Apophis orbit. With a chemical or electric propulsion system, however, many gravity assists and thus a long time is required to achieve this. We show in this paper that the solar sail might be the better propulsion system for such a mission: a solar sail Kinetic Energy Impactor (KEI) spacecraft could impact Apophis from a retrograde trajectory with a very high relative velocity (75-80 km/s) during one of its perihelion passages. The spacecraft consists of a 160 m × 160 m, 168 kg solar sail assembly and a 150 kg impactor. Although conventional spacecraft can also achieve the required minimum deflection of 1 km for this approx. 320 m-sized object from a prograde trajectory, our solar sail KEI concept also allows the deflection of larger objects. For a launch in 2020, we also show that, even after Apophis has flown through one of the gravitational keyholes in 2029, the solar sail KEI concept is still feasible to prevent Apophis from impacting the Earth, but many KEIs would be required for consecutive impacts to increase the total Earth-miss distance to a safe value}, language = {en} } @article{WagnerMolinaYoshinobuetal.2007, author = {Wagner, Torsten and Molina, Roberto and Yoshinobu, Tatsuo and Kloock, Joachim P. and Biselli, Manfred and Canzoneri, Michele and Schnitzler, Thomas and Sch{\"o}ning, Michael Josef}, title = {Handheld multi-channel LAPS device as a transducer platform for possible biological and chemical multi-sensor applications}, series = {Electrochimica Acta. 53 (2007), H. 2}, journal = {Electrochimica Acta. 53 (2007), H. 2}, isbn = {0013-4686}, pages = {305 -- 311}, year = {2007}, language = {en} } @article{WagnerMarisAckermannetal.2007, author = {Wagner, Torsten and Maris, Rob J. and Ackermann, Hans-Josef and Otto, Ralph and Beging, Stefan and Poghossian, Arshak and Sch{\"o}ning, Michael Josef}, title = {Handheld measurement device for field-effect sensor structures: Practical evaluation and limitations}, series = {Sensors and Actuators B: Chemical . 127 (2007), H. 1}, journal = {Sensors and Actuators B: Chemical . 127 (2007), H. 1}, isbn = {0925-4005}, pages = {217 -- 223}, year = {2007}, language = {en} } @book{Benkner2007, author = {Benkner, Thorsten}, title = {Grundlagen des Mobilfunks}, publisher = {Schlembach}, address = {Wilburgstetten}, isbn = {978-3-935340-44-1}, pages = {IX, 374 S.}, year = {2007}, language = {de} } @article{KraftNagl2007, author = {Kraft, Bodo and Nagl, Manfred}, title = {Graphbasierte Werkzeuge zur Unterst{\"u}tzung des konzeptuellen Geb{\"a}udeentwurfs}, series = {Vernetzt-kooperative Planungsprozesse im Konstruktiven Ingenieurbau : Grundlagen, Methoden, Anwendung und Perspektiven zur vernetzten Ingenieurkooperation / Uwe R{\"u}ppel (Hrsg.)}, journal = {Vernetzt-kooperative Planungsprozesse im Konstruktiven Ingenieurbau : Grundlagen, Methoden, Anwendung und Perspektiven zur vernetzten Ingenieurkooperation / Uwe R{\"u}ppel (Hrsg.)}, publisher = {Springer}, address = {Berlin}, isbn = {978-3-540-68102-1}, pages = {155 -- 175}, year = {2007}, language = {de} } @article{Olbertz2007, author = {Olbertz, Klaus}, title = {Gleichstellungsabrede - Gestaltungsm{\"o}glichkeiten und -notwendigkeiten f{\"u}r die betriebliche Praxis}, series = {Betriebs-Berater: BB ; Recht, Wirtschaft, Steuern}, journal = {Betriebs-Berater: BB ; Recht, Wirtschaft, Steuern}, issn = {0340-7918}, pages = {2737}, year = {2007}, language = {de} } @techreport{HellmannsHesse2007, author = {Hellmanns, Mark and Hesse, Joachim}, title = {Ger{\"a}uschminderung und Leichtbau in Leistungsgetrieben durch den Einsatz von Werkstoffverbunden : Abschlussbericht zu Nr. 3.1 : Berichtszeitraum: 1.3.2005 - 31.8.2007}, publisher = {Bundesministerium f{\"u}r Wirtschaft und Arbeit (BMWi)}, address = {Berlin}, pages = {66 S.}, year = {2007}, language = {de} } @article{Feiser2007, author = {Feiser, Johannes}, title = {Geotechnik}, series = {Bautechnische Zahlentafeln / Wendehorst, Reinhard ; Wetzell, Otto W.
