We use the finite-elements method to analyze the conceptual design of an in-line thermal evaporation unit to produce a heated gas mixture of air and evaporated H2O2 solution. For the numerical model, the required phase-transition variables of pure H2O2 solution and of the aerosol mixture are acquired from vapor-liquid equilibrium (VLE) diagrams derived from vapor-pressure formulations. This work combines homogeneous single-phase turbulent flow with heat-transfer physics to describe the operation of the evaporation unit. We introduce the apparent heat-capacity concept to approximate the non-isothermal phase-transition process of the H2O2-containing aerosol. Empirical and analytical functions are defined to represent the temperature- and pressure-dependent material properties of the aqueous H2O2 solution, the aerosol and the gas mixture. To validate the numerical model, the simulation results are compared to experimental data on the heating power required to produce the gas mixture. This shows good agreement with the deviations below 10\%. Experimental observations on the formation of deposits due to the evaporation of stabilized H2O2 solution fits the prediction made from simulation results.}, language = {en} } @inproceedings{EngemannBadriWenningetal.2019, author = {Engemann, Heiko and Badri, Sriram and Wenning, Marius and Kallweit, Stephan}, title = {Implementation of an Autonomous Tool Trolley in a Production Line}, series = {Advances in Service and Industrial Robotics.

By comparing two images, one of the undeformed reference state of a specimen and another of the deformed target state, the relative displacement between those two states is determined. DIC is well known and often used for post-processing analysis of in-plane displacements and deformation of specimen. Increasing the analysis speed to enable real-time DIC analysis will be beneficial and extend the field of use of this technique. Here we tested several combinations of the most common DIC methods in combination with different parallelization approaches in MATLAB and evaluated their performance to determine whether real-time analysis is possible with these methods. To reflect improvements in computing technology different hardware settings were also analysed. We found that implementation problems can reduce the efficiency of a theoretically superior algorithm such that it becomes practically slower than a suboptimal algorithm. The Newton-Raphson algorithm in combination with a modified Particle Swarm algorithm in parallel image computation was found to be most effective. This is contrary to theory, suggesting that the inverse-compositional Gauss-Newton algorithm is superior. As expected, the Brute Force Search algorithm is the least effective method. We also found that the correct choice of parallelization tasks is crucial to achieve improvements in computing speed. A poorly chosen parallelisation approach with high parallel overhead leads to inferior performance. Finally, irrespective of the computing mode the correct choice of combinations of integerpixel and sub-pixel search algorithms is decisive for an efficient analysis. Using currently available hardware realtime analysis at high framerates remains an aspiration.}, 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{MatchaLjubasGueldemet2018, author = {Matcha, Heike and Ljubas, Ante and Gueldemet, Harun}, title = {Printing a Coffee Bar: An investigation into mid-scale 3D printing}, series = {Computing for a better tomorrow - Proceedings of the 36th eCAADe Conference - Volume 2, Lodz University of Technology, Lodz, Poland, 19-21 September 2018}, journal = {Computing for a better tomorrow - Proceedings of the 36th eCAADe Conference - Volume 2, Lodz University of Technology, Lodz, Poland, 19-21 September 2018}, editor = {Kepczynska-Walczak, A.}, pages = {59 -- 68}, year = {2018}, abstract = {We present and discuss an exploration of the possibilities and properties of 3D printing with a printing space of 1 cubic meter, and how those can be integrated into architectural education through an experimental design and research course with students of architecture.We expand on issues presented at the eCAADe conference 2017 in Rome [Ref 6] by increasing the complexity and size of our prints, printing not a model to scale, but a full scale funtional prototype of a usable architectural object: A coffee bar.}, language = {en} } @inproceedings{Kern2017, author = {Kern, Alexander}, title = {Optimierung des Blitzschutzes bei Biogasanlagen}, series = {12.

Material and methods. The vitreous contents of the eyes from 2 groups were studied. The 1st group included 15 cadaveric eyes; the 2nd group included 15 eyes with refractory glaucoma in the terminal stage of the disease with decompensated IOP in patients with hypertension pain. The vitreal content samples were taken in the course of antiglaucoma surgery aimed at preserving the eye as an organ and involving employment of drainage in the vitreous cavity. The study of virtual contents was carried out on energy dispersive spectrometer Oxford X-Max 50 integrated into scanning electron microscope Zeiss EVO LS10. Results. Increased concentrations of Kalium and Phosphorus were detected in the vitreous content of cadaveric eyes compared with the vitreal content from the eyes with terminal glaucoma with decompensated IOP taken in vivo (K — 0.172/0.093; P — 0.045/0.025 mmol/L). In the vitreous cavity in the eyes with end-stage glaucoma with decompensated IOP, the concentration of Nitrogen was higher in comparison with human cadaver eyes (2.030/1.424 mmol/L). Conclusion. The increased concentrations of Kalium and Phosphorus in the vitreous content of cadaveric eyes is associated with postmortem autolytic processes and with the release of intracellular content in the destruction of cell membranes. The increased Nitrogen concentration in the vitreal contents of the eyes with terminal stage glaucoma with decompensated IOP may be associated with the presence of osmotically active nitrogen-containing compounds in the eyes with increased IOP.}, language = {ru} } @inproceedings{HoevelerJanser2016, author = {Hoeveler, Bastian and Janser, Frank}, title = {The aerodynamically optimized design of a fan-in-wing duct}, series = {Applied Aerodynamics Research Conference 2016, Bristol, GB, Jul 19-21, 2016}, booktitle = {Applied Aerodynamics Research Conference 2016, Bristol, GB, Jul 19-21, 2016}, isbn = {1-85768-371-4}, pages = {1 -- 10}, year = {2016}, language = {en} } @article{CapriMorsianiSantoroetal.2019, author = {Capri, Miriam and Morsiani, Cristina and Santoro, Aurelia and Moriggi, Manuela and Conte, Maria and Martucci, Morena and Bellavista, Elena and Fabbri, Cristina and Giampieri, Enrico and Albracht, Kirsten and Fl{\"u}ck, Martin and Ruoss, Severin and Brocca, Lorenza and Canepari, Monica and Longa, Emanuela and Giulio, Irene Di and Bottinelli, Roberto and Cerretelli, Paolo and Salvioli, Stefano and Gelfi, Cecilia and Franceschi, Claudio and Narici, Marco and Rittweger, J{\"o}rn}, title = {Recovery from 6-month spaceflight at the International Space Station: muscle-related stress into a proinflammatory setting}, series = {The FASEB journal : official publication of the Federation of American Societies for Experimental Biology}, volume = {33}, journal = {The FASEB journal : official publication of the Federation of American Societies for Experimental Biology}, number = {4}, doi = {10.1096/fj.201801625R}, pages = {5168 -- 5180}, year = {2019}, language = {en} } @inproceedings{GaldiHartungDugelay2019, author = {Galdi, Chiara and Hartung, Frank and Dugelay, Jean-Luc}, title = {Socrates: A database of realistic data for source camera recognition on smartphones}, series = {Proceedings of the 8th International Conference on Pattern Recognition Applications and Methods - Volume 1: ICPRAM}, booktitle = {Proceedings of the 8th International Conference on Pattern Recognition Applications and Methods - Volume 1: ICPRAM}, isbn = {978-989-758-351-3}, doi = {10.5220/0007403706480655}, pages = {648 -- 655}, year = {2019}, language = {en} } @article{QuittmannAbelAlbrachtetal.2019, author = {Quittmann, Oliver J. and Abel, Thomas and Albracht, Kirsten and Str{\"u}der, Heiko K.}, title = {Reliability of muscular activation patterns and their alterations during incremental handcycling in able-bodied participants}, series = {Sports Biomechanics}, journal = {Sports Biomechanics}, number = {Article in press}, publisher = {Taylor \& Francis}, address = {London}, issn = {1752-6116}, doi = {10.1080/14763141.2019.1593496}, year = {2019}, language = {en} } @article{SchmidtForkmannSchultzetal.2019, author = {Schmidt, Katharina and Forkmann, Katarina and Schultz, Heidrun and Gratz, Marcel and Bitz, Andreas and Wiech, Katja and Bingel, Ulrike}, title = {Enhanced Neural Reinstatement for Evoked Facial Pain Compared With Evoked Hand Pain}, series = {The Journal of Pain}, journal = {The Journal of Pain}, number = {In Press, Corrected Proof}, publisher = {Elsevier}, address = {Amsterdam}, issn = {1526-5900}, doi = {10.1016/j.jpain.2019.03.003}, year = {2019}, language = {en} } @inproceedings{BosseDeClercqBarnat2018, author = {Bosse, Elke and De Clercq, Mikael and Barnat, Miriam}, title = {The Role of Diversity for the Transition to Higher Education}, series = {EARLI SIG 4, Giessen}, booktitle = {EARLI SIG 4, Giessen}, pages = {13 Folien}, year = {2018}, language = {en} } @inproceedings{HoffmannNierenGaebetal.2019, author = {Hoffmann, Katharina and Nieren, Monika and G{\"a}b, Martina and Kasper, Anna and Elbers, Gereon}, title = {The potential of near infrared spectroscopy (NIRS) for the environmental biomonitoring of plants}, series = {International conference on Life Sciences and Technology}, volume = {276}, booktitle = {International conference on Life Sciences and Technology}, number = {012009}, issn = {1755-1315}, doi = {10.1088/1755-1315/276/1/012009}, pages = {1 -- 3}, year = {2019}, abstract = {In the current environmental condition, the increase in pollution of the air, water, and soil indirectly will induce plants stress and decrease vegetation growth rate.

The assumption of constant task execution times during allocation planning is even more unlikely in a cloud environment where virtualized resources vary in performance. Revising the initially created resource allocation plan at runtime allows the scheduler to react on deviations between planning and execution. Such an adaptive rescheduling of a many-task application workflow is only feasible, when the planning time can be handled efficiently at runtime. In this paper, we present the static low-complexity resource allocation planning algorithm (LCP) applicable to efficiently schedule many-task scientific application workflows on cloud resources of different capabilities. The benefits of the presented algorithm are benchmarked against alternative approaches. The benchmark results show that LCP is not only able to compete against higher complexity algorithms in terms of planned costs and planned makespan but also outperforms them significantly by magnitudes of 2 to 160 in terms of required planning time. Hence, LCP is superior in terms of practical usability where low planning time is essential such as in our targeted online rescheduling scenario.}, language = {en} } @article{NoureddineKraffLaddetal.2019, author = {Noureddine, Yacine and Kraff, Oliver and Ladd, Mark E. and Wrede, Karsten and Chen, Bixia and Quick, Harald H. and Schaefers, Georg and Bitz, Andreas}, title = {Radiofrequency induced heating around aneurysm clips using a generic birdcage head coil at 7 Tesla under consideration of the minimum distance to decouple multiple aneurysm clips}, series = {Magnetic Resonance in Medicine}, journal = {Magnetic Resonance in Medicine}, number = {Early view}, publisher = {Wiley}, address = {Weinheim}, issn = {1522-2594}, doi = {10.1002/mrm.27835}, pages = {1 -- 17}, year = {2019}, language = {en} } @incollection{Sparla2019, author = {Sparla, Peter}, title = {Vermessung}, series = {{\"U}bungsaufgaben und Berechnungen f{\"u}r den Baubetrieb}, booktitle = {{\"U}bungsaufgaben und Berechnungen f{\"u}r den Baubetrieb}, publisher = {Springer Vieweg}, address = {Wiesbaden}, isbn = {978-3-658-23127-9}, doi = {10.1007/978-3-658-23127-9_2}, pages = {13 -- 61}, year = {2019}, language = {de} } @incollection{Ulke2019, author = {Ulke, Bernd}, title = {Der baurechtliche Vertrag}, series = {{\"U}bungsaufgaben und Berechnungen f{\"u}r den Baubetrieb}, booktitle = {{\"U}bungsaufgaben und Berechnungen f{\"u}r den Baubetrieb}, publisher = {Springer Vieweg}, address = {Wiesbaden}, isbn = {978-3-658-23127-9}, pages = {63 -- 87}, year = {2019}, abstract = {Anhand von kurzen theoretischen Einf{\"u}hrungen werden anhand von Beispielen die wesentlichen Aspekte des baurechtlichen Vertrages erl{\"a}utert.

In this paper we have investigated whether the gas phase coating technique Atomic Layer Deposition (ALD), which can deposit ultra-thin layers on high surface area materials, can be used to attain materials with high adsorption capacity for ⁹⁹Mo. For this purpose, ALD was applied on a silica-core sorbent material to coat it with a thin layer of alumina.

A highly competitive market requires the use of high performance metals and composite materials in combination with reduced manufacturing cost and time as well as a minimization of the time to market for a new product. However, the use of such materials is expensive and requires sophisticated manufacturing processes. An experience based process and tooling design followed by a lengthy trial-and-error optimization is just not contemporary anymore. Instead, a tooling design process aided by simulation is used more often. This paper provides an overview of the capabilities of MPS in the fields of sheet metal forming and prepreg autoclave manufacturing of composite parts summarizing the resulting benefits for tooling design and manufacturing engineering. The simulation technology is explained briefly in order to show several simplification and optimization techniques for developing industrialized simulation approaches.

To achieve a high part quality at low cycle times, the thermal behavior of the autoclave mold can be investigated by means of simulations. Most challenging for such a simulation is the generation of necessary boundary conditions. Heat-up and temperature distribution in an autoclave mold are governed by flow phenomena, tooling material and shape, position within the autoclave, and the chosen autoclave cycle. This paper identifies and summarizes the most important factors influencing mold heat-up and how they can be introduced into a thermal simulation. Thermal measurements are used to quantify the impact of the various parameters. Finally, the gained knowledge is applied to develop a semi-empirical approach for boundary condition estimation that enables a simple and fast thermal simulation of the autoclave curing process with reasonably high accuracy for tooling optimization.}, language = {en} } @inproceedings{HailerWeberArent2019, author = {Hailer, Benjamin and Weber, Tobias and Arent, Jan-Christoph}, title = {Manufacturing Process Simulation for Autoclave-Produced Sandwich Structures}, series = {Proceedings of SAMPE Europe Conference 2019, Nantes, France}, booktitle = {Proceedings of SAMPE Europe Conference 2019, Nantes, France}, pages = {1 -- 8}, year = {2019}, language = {en} } @inproceedings{WeberEnglhardHaileretal.2019, author = {Weber, Tobias and Englhard, Markus and Hailer, Benjamin and Arent, Jan-Christoph}, title = {Manufacturing Process Simulation for the Prediction of Tool-Part-Interaction and Ply Wrinkling}, series = {Proceedings of SAMPE Europe Conference 2019, Nantes, France}, booktitle = {Proceedings of SAMPE Europe Conference 2019, Nantes, France}, pages = {1 -- 10}, year = {2019}, language = {en} }
