First, a focus group with room acoustical experts determined relevant aspects of room acoustical impression in the form of a comprehensive list of 50 uni- and bipolar items in different categories. Then, n = 190 subjects rated their acoustical impression of 35 binaurally simulated rooms from 2 listening positions, with symphonic orchestra, solo trumpet, and dramatic speech as audio content. Subsequent explorative and confirmative factor analyses of the questionnaire data resulted in three possible solutions with four, six, and nine factors of room acoustical impression. The factor solutions, as well as the related RAQI items, were tested in terms of reliability, validity, and several types of measurement invariance, and were cross-validated by a follow-up experiment with a subsample of 46\% of the original participants, which provided re-test reliabilities and stability coefficients for all RAQI constructs. The resulting psychometrically evaluated measurement instrument can be used for room quality assessment, acoustical planning, and the further development of room acoustical parameters in order to predict primary acoustical qualities of venues for music and speech.}, language = {en} } @article{SchreiberStruminksi2018, author = {Schreiber, Andreas and Struminksi, Regina}, title = {Visualizing the Provenance of Personal Data Using Comics}, series = {Computers}, volume = {7}, journal = {Computers}, number = {1}, publisher = {MDPI}, issn = {2073-431X}, doi = {10.3390/computers7010012}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-40286}, year = {2018}, language = {en} } @article{SchittkowskiRulandLaudenschlegeretal.2018, author = {Schittkowski, Julian and Ruland, Holger and Laudenschleger, Daniel and Girod, Kai and K{\"a}hler, Kevin and Kaluza, Stefan and Muhler, Martin and Schl{\"o}gl, Robert}, title = {Methanol Synthesis from Steel Mill Exhaust Gases: Challenges for the Industrial Cu/ZnO/Al 2 O 3 Catalyst}, series = {Chemie Ingenieur Technik}, volume = {90}, journal = {Chemie Ingenieur Technik}, number = {10}, publisher = {Wiley}, issn = {1522-2640}, doi = {10.1002/cite.201800017}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-34526}, pages = {1419 -- 1429}, year = {2018}, language = {en} } @article{Spiegel2018, author = {Spiegel, Thomas}, title = {Impact of Renewable Energy Expansion to the Balancing Energy Demand of Differential Balancing Groups}, series = {Journal of Sustainable Development of Energy, Water and Environment Systems}, volume = {6}, journal = {Journal of Sustainable Development of Energy, Water and Environment Systems}, number = {4}, publisher = {SDEWES}, issn = {1848-9257}, doi = {10.13044/j.sdewes.d6.0215}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-29207}, pages = {784 -- 799}, year = {2018}, abstract = {The research addresses the present situation on the German electricity market caused by variable renewable energy sources. 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{PfeiffelmannBenim2018, author = {Pfeiffelmann, Bj{\"o}rn and Benim, Ali Cemal}, title = {Numerical study of the quenching of a laminar premixed hydrogen flame}, series = {MATEC Web of Conferences}, volume = {240}, journal = {MATEC Web of Conferences}, publisher = {edp sciences}, issn = {2261-236X}, doi = {10.1051/matecconf/201824001031}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-27976}, year = {2018}, language = {en} } @article{IqbalPfeiffelmannBenimetal.2018, author = {Iqbal, Sohail and Pfeiffelmann, Bj{\"o}rn and Benim, Ali Cemal and Joos, Franz}, title = {Numerical analysis of lifted hydrogen flame}, series = {MATEC Web of Conferences}, volume = {240}, journal = {MATEC Web of Conferences}, publisher = {edp sciences}, issn = {2261-236X}, doi = {10.1051/matecconf/201824001014}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-27950}, year = {2018}, language = {en} } @article{SaeedrashedBenim2018, author = {Saeedrashed, Younis Saida and Benim, Ali Cemal}, title = {A computational investigation of the hydrodynamics of the Badush dam in northern Iraq}, series = {MATEC Web of Conferences}, volume = {240}, journal = {MATEC Web of Conferences}, publisher = {edp sciences}, issn = {2261-236X}, doi = {10.1051/matecconf/201824004009}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-27997}, year = {2018}, language = {en} } @article{PfeiffelmannBenimJoos2018, author = {Pfeiffelmann, Bj{\"o}rn and Benim, Ali Cemal and Joos, Franz}, title = {Numerical analysis of liquid jet impingement cooling of a thermoelectric generator}, series = {MATEC Web of Conferences}, volume = {240}, journal = {MATEC Web of Conferences}, publisher = {edp sciences}, issn = {2261-236X}, doi = {10.1051/matecconf/201824001032}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-27988}, year = {2018}, language = {en} } @article{NiemannPisla2018, author = {Niemann, J{\"o}rg and Pisla, Adrian}, title = {Sustainable Potentials and Risks Assess in Automation and Robotization Using the Life Cycle Management Index Tool—LY-MIT}, series = {Sustainability}, volume = {10}, journal = {Sustainability}, number = {12}, publisher = {MDPI}, issn = {2071-1050}, doi = {10.3390/su10124638}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-27966}, year = {2018}, language = {en} }
