Focusing on a relatively neglected, but in times of globalization even more important aspect, the infuence of cultural characteristics on innovativeness, we apply diferent econometric models to test for links between cultural tightness and looseness on the one hand, and national innovativeness on the other hand. We fnd that cultural tightness—in the sense of homogenous and intolerant societies—has a negative link to national innovativeness, while cultural looseness—in the sense of tolerant and diverse societies—displays a positive link to national innovativeness.}, subject = {Innovation}, language = {en} } @article{KrebsMuellerBraun2021, author = {Krebs, Christian and M{\"u}ller, Patrick and Braun, Alexander}, title = {Impact of Windshield Optical Aberrations on Visual Range Camera Based Classification Tasks Performed by CNNs}, series = {London Imaging Meeting}, volume = {2021}, journal = {London Imaging Meeting}, number = {1}, publisher = {Ingenta connect}, isbn = {0-89208-346-6}, issn = {2694-118X}, doi = {10.2352/issn.2694-118X.2021.LIM-83}, pages = {83 -- 87}, year = {2021}, language = {de} } @article{MuellerBrummelBraun2021, author = {M{\"u}ller, Patrick and Brummel, Mattis and Braun, Alexander}, title = {Spatial recall index for machine learning algorithms}, series = {London Imaging Meeting}, volume = {2021}, journal = {London Imaging Meeting}, number = {1}, publisher = {Society for Imaging Science and Technology}, isbn = {0-89208-346-6}, doi = {10.2352/issn.2694-118X.2021.LIM-58}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-35657}, pages = {58 -- 62}, year = {2021}, abstract = {We present a novel metric Spatial Recall Index to assess the performance of machine-learning (ML) algorithms for automotive applications, focusing on where in the image which performance occurs. Typical metrics like intersection-over-union (IoU), precisionrecallcurves or average precision (AP) quantify the performance over a whole database of images, neglecting spatial performance variations. But as the optics of camera systems are spatially variable over the field of view, the performance of ML-based algorithms is also a function of space, which we show in simulation: A realistic objective lens based on a Cooke-triplet that exhibits typical optical aberrations like astigmatism and chromatic aberration, all variable over field, is modeled. The model is then applied to a subset of the BDD100k dataset with spatially-varying kernels. We then quantify local changes in the performance of the pre-trained Mask R-CNN algorithm. Our examples demonstrate the spatial dependence of the performance of ML-based algorithms from the optical quality over field, highlighting the need to take the spatial dimension into account when training ML-based algorithms, especially when looking forward to autonomous driving applications.}, language = {en} } @article{BenimPfeiffelmann2020, author = {Benim, Ali Cemal and Pfeiffelmann, Bj{\"o}rn}, title = {Comparison of Combustion Models for Lifted Hydrogen Flames within RANS Framework}, series = {Energies}, volume = {13}, journal = {Energies}, number = {1}, publisher = {MDPI}, issn = {1996-1073}, doi = {10.3390/en13010152}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-27727}, pages = {152}, year = {2020}, language = {en} } @article{FominPetelinJahr2020, author = {Fomin, Alexey and Petelin, Daniil and Jahr, Andreas}, title = {Synthesis and Analysis of a Novel Linkage Mechanism with the Helical Motion of the End-Effector}, series = {Robotics}, volume = {9}, journal = {Robotics}, number = {3}, publisher = {MDPI}, issn = {2218-6581}, doi = {10.3390/robotics9030053}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-27736}, pages = {1 -- 15}, year = {2020}, language = {en} } @article{ShahzadGulistanAlietal.2020, author = {Shahzad, Azeem and Gulistan, Uzma and Ali, Ramzan and Iqbal, Azhar and Benim, Ali Cemal and Kamran, Muhammad and Khan, Salah Ud-Din and Khan, Shahab Ud-Din and Farooq, Aamir}, title = {Numerical Study of Axisymmetric Flow and Heat Transfer in a Liquid Film over an Unsteady Radially Stretching Surface}, series = {Mathematical Problems in Engineering}, volume = {2020}, journal = {Mathematical Problems in Engineering}, publisher = {Hindawi}, doi = {10.1155/2020/6737243}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-27755}, pages = {1 -- 9}, year = {2020}, language = {en} } @article{GirodLohmannSchlueteretal.2020, author = {Girod, Kai and Lohmann, Heiko and Schl{\"u}ter, Stefan and Kaluza, Stefan}, title = {Methanol Synthesis with Steel-Mill Gases: Simulation and Practical Testing of Selected Gas Utilization Scenarios}, series = {Processes}, volume = {8}, journal = {Processes}, number = {12}, publisher = {MDPI}, doi = {10.3390/pr8121673}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-26928}, year = {2020}, language = {en} } @article{GlembinAdamDeidertetal.2012, author = {Glembin, Jens and Adam, Mario and Deidert, J{\"o}rn and Jagnow, Kati and Rockendorf, Gunter and Wirth, Hans Peter}, title = {Simulation and Evaluation of Different Boiler Implementations and Configurations in Solar Thermal Combi Systems}, series = {Energy Procedia}, volume = {30}, journal = {Energy Procedia}, publisher = {Elsevier}, doi = {10.1016/j.egypro.2012.11.070}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-27350}, pages = {601 -- 610}, year = {2012}, language = {en} } @article{SchrammAdam2014, author = {Schramm, Sebastian and Adam, Mario}, title = {Storage in Solar Process Heat Applications}, series = {Energy Procedia}, volume = {48}, journal = {Energy Procedia}, publisher = {Elsevier}, issn = {1876-6102}, doi = {10.1016/j.egypro.2014.02.136}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-27244}, pages = {1202 -- 1209}, year = {2014}, language = {en} } @article{MoellmannHungerDusendetal.2019, author = {M{\"o}llmann, Anne and Hunger, Antje and Dusend, Christina and van den Hout, Marcel and Buhlmann, Ulrike}, title = {Gazing at facial features increases dissociation and decreases attractiveness ratings in non-clinical females - A potential explanation for a common ritual in body dysmorphic disorder}, series = {PloS one}, volume = {14}, journal = {PloS one}, number = {7}, publisher = {PLoS}, organization = {PLoS}, doi = {10.1371/journal.pone.0219791}, year = {2019}, abstract = {Rituals, such as gazing at faces, are common in body dysmorphic disorder (BDD) and appear in cognitive-behavioral models as a maintaining factor.

Currently, there are no means available to detect ash in flight as the particles are too fine (radii < 30 μm) for on-board radar detection and, even in good visibility, ash clouds are difficult or impossible to detect by eye. The economic cost and societal impact of the April/May 2010 Icelandic eruption of Eyjafjallaj{\"o}kull generated renewed interest in finding ways to identify airborne volcanic ash in order to keep airspace open and avoid aircraft groundings. We have designed and built a bi-spectral, fast-sampling, uncooled infrared camera device (AVOID) to examine its ability to detect volcanic ash from commercial jet aircraft at distances of more than 50 km ahead. Here we report results of an experiment conducted over the Atlantic Ocean, off the coast of France, confirming the ability of the device to detect and quantify volcanic ash in an artificial ash cloud created by dispersal of volcanic ash from a second aircraft. A third aircraft was used to measure the ash in situ using optical particle counters. The cloud was composed of very fine ash (mean radii ~10 μm) collected from Iceland immediately after the Eyjafjallaj{\"o}kull eruption and had a vertical thickness of ~200 m, a width of ~2 km and length of between 2 and 12 km. Concentrations of ~200 μg m(-3) were identified by AVOID at distances from ~20 km to ~70 km.

The increasing number of households with photovoltaic and battery storage systems and their impacts require special attention. These systems change the traditional electricity customer from the sole electricity consumer to an electricity producer and consumer in one person. These so-called prosumers differ in their actual electricity demand from the initially estimated electricity demand with standard load profile. This discrepancy results in deviations within a differential balancing group. Thereby, the main finding of this research is a significant higher balancing energy demand with the expansion of photovoltaic and battery storage systems. Hence, the standard load profile is particularly not suitable for differential balancing groups with a high penetration of solar systems and still less suitable for groups with solar and battery storage systems}, language = {en} } @article{BonkLauxRoedderetal.2017, author = {Bonk, Christian Dirk and Laux, Christoph and R{\"o}dder, Maximilian and Neef, Matthias}, title = {Design of a 1 KW Organic Rankine Cycle for Teaching and Research Issues}, series = {Energy Procedia}, volume = {129}, journal = {Energy Procedia}, publisher = {Elsevier}, doi = {10.1016/j.egypro.2017.09.117}, pages = {931 -- 938}, year = {2017}, abstract = {This paper deals with the design of a micro-scale ORC plant for teaching and research including the development of an automated control concept. The aim is to provide a safe and environmentally acceptable micro-scale heat engine, which can be developed, implemented and used in university labs for the education of students as well as for small research projects. The test rig allows the support of several learning outcomes on a multi-disciplinary level particularly for the implementation and simulation of small power systems. Special attention was given to the organic working fluid characteristics and its selection process. In addition to the above-mentioned performance goals, favourable safety properties and low global warming potential were decisive in the selection of the novel organic fluid called 3M™ Novec™ 649. The performance and the fluid behaviour of Novec 649 in a micro-scale power cycle are of major interest and the research goal for the test rig presented in this paper. Due to the expected power output of 1 kW, a scroll expander was chosen as the generator drive for the micro plant. In order to design the major parts of the ORC, the thermodynamic simulation software EBSILON®Professional was used. The supply temperature was set to 140 °C. As a result of the simulation, feasible expander inlet pressures spread from 5.5 bar to 8.5 bar. This leads to thermal efficiencies of the ORC in the order of 5 \%. Adding a recuperator to the cycle system decreases the operating pressure range but in the end, the thermal efficiency can be increased by 1.5 \%-points up to 6.2 \%. Finally, an automated control concept is introduced, where the pump is controlled via the fill level measurement system.}, language = {en} }
