A potential major disaster at an industrial site could affect several countries, probably far beyond the country where it is located. However, the seismic design and safety assessment of these facilities is practically based on national, often outdated seismic hazard assessment studies, due to many reasons, including the absence of a reliable, commonly developed seismic hazard model for whole Europe. This important gap is no more existing, as the 2020 European Seismic Hazard Model ESHM20 was released in December 2021. In this paper we investigate the expected impact of the adoption of ESHM20 on the seismic demand for industrial facilities, through the comparison of the ESHM20 probabilistic hazard at the sites where industrial facilities are located with the respective national and European regulations. The goal of this preliminary work in the framework of Working Group 13 of the European Association for Earthquake Engineering (EAEE), is to identify potential inadequacies in the design and safety control of existing industrial facilities and to highlight the expected impact of the adoption of the new European Seismic Hazard Model on the design of new industrial facilities and the safety assessment of existing ones.}, language = {en} } @inproceedings{RingbeckAlbrechtFreyetal.2003, author = {Ringbeck, Thorsten and Albrecht, M. and Frey, J. and [u.a.],}, title = {Time-of-Flight 3D-camera for autonomous navigation and industrial automation}, series = {Proceedings : 11th international conference, 13 - 15 May 2003, Exhibition Centre Nuremberg, Germany ; an event of the Association for Sensor Technology, AMA}, booktitle = {Proceedings : 11th international conference, 13 - 15 May 2003, Exhibition Centre Nuremberg, Germany ; an event of the Association for Sensor Technology, AMA}, editor = {Lerch, Reinhard}, edition = {CD-ROM-Ausg.}, publisher = {AMA Service}, address = {Wunstorf/Germany}, year = {2003}, language = {en} } @inproceedings{RingbeckBuxbaum2000, author = {Ringbeck, Thorsten and Buxbaum, Bernd}, title = {A highly integrated monolithic electro-optical PLL in CMOS-technology (PMD-PLL) for communication and ranging systems}, series = {Proceedings / OPTO 2000, 4th International Conference and Exhibition on Optoelectronics, Optical Sensors and Measuring Techniques : May 9 - 11, 2000, Erfurt Fair, Conference Centre}, booktitle = {Proceedings / OPTO 2000, 4th International Conference and Exhibition on Optoelectronics, Optical Sensors and Measuring Techniques : May 9 - 11, 2000, Erfurt Fair, Conference Centre}, publisher = {AMA Service GmbH}, address = {Wunsdorf}, pages = {235 -- 239}, year = {2000}, language = {en} } @inproceedings{RingbeckHagebeuker2007, author = {Ringbeck, Thorsten and Hagebeuker, Bianca}, title = {A 3D time of flight camera of object detection}, series = {Optical 3-D measurement techniques VIII : applications in GIS, mapping, manufacturing, quality control, robotics, navigation, mobile mapping, medical imaging, cultural heritage, VR generation and animation; papers presented to the conference organized at ETH Zurich, Switzerland, July 9 - 12, 2007. - Vol. 1}, booktitle = {Optical 3-D measurement techniques VIII : applications in GIS, mapping, manufacturing, quality control, robotics, navigation, mobile mapping, medical imaging, cultural heritage, VR generation and animation; papers presented to the conference organized at ETH Zurich, Switzerland, July 9 - 12, 2007. - Vol. 1}, editor = {Gr{\"u}n, Armin}, publisher = {ETH}, address = {Z{\"u}rich}, isbn = {3-906467-67-8 (Gesamtwerk)}, pages = {1 -- 16}, year = {2007}, language = {en} } @inproceedings{RingbeckSchwarteBuxbaum1999, author = {Ringbeck, Thorsten and Schwarte, Rudolf and Buxbaum, Bernd}, title = {Introduction of a new opto-electrical phase-locked loop in CMOS technology: the PMD-PLL}, series = {Optical wireless communications II / [SPIE Conference on Optical Wireless Communications II], 22 September 1999, Boston, Massachusetts. - (SPIE proceedings series ; 3850)}, booktitle = {Optical wireless communications II / [SPIE Conference on Optical Wireless Communications II], 22 September 1999, Boston, Massachusetts. - (SPIE proceedings series ; 3850)}, editor = {Korevaar, Eric John}, publisher = {SPIE}, address = {Bellingham, Wash.}, isbn = {0-8194-3443-4}, issn = {0038-7355}, pages = {108 -- 116}, year = {1999}, language = {en} } @inproceedings{RingbeckSchwarteBuxbaumetal.2001, author = {Ringbeck, Thorsten and Schwarte, Rudolf and Buxbaum, Bernd and Hess, Rudolf}, title = {Optical GMSK modem for infrared wireless communication based on a new receiver principle in CMOS technology}, series = {Optoelectronic interconnects VIII : 25 - 26 January 2001, San Jose, USA. - (Proceedings of SPIE ; 4292)}, booktitle = {Optoelectronic interconnects VIII : 25 - 26 January 2001, San Jose, USA. - (Proceedings of SPIE ; 4292)}, editor = {Tang, Suning}, publisher = {SPIE}, address = {Bellingham, Wash.}, isbn = {0-8194-3970-3}, issn = {0038-7355}, pages = {25 -- 34}, year = {2001}, language = {en} } @inproceedings{RingsLudowicyFingeretal.2019, author = {Rings, Ren{\´e} and Ludowicy, Jonas and Finger, Felix and Braun, Carsten and Bil, Cees}, title = {Sensitivity Analysis of General Aviation Aircraft with Parallel Hybrid-Electric Propulsion Systems}, series = {Asia Pacific International Symposium on Aerospace Technology.

In case of seismic excitation, these constructions are highly vulnerable to stability failures. An earthquake-resistant design of rigidly supported tanks for high seismic loading demands, however, uneconomic wall thicknesses. A cost-effective alternative can be provided by base isolation systems. In this paper, a simplified seismic design procedure for base isolated tanks is introduced, by appropriately modifying the standard mechanical model for flexible, rigidly supported tanks. The non-linear behavior of conventional base isolation systems becomes an integral part of a proposed simplified process, which enables the assessment of the reduced hydrodynamic forces acting on the tank walls and the corresponding stress distribution. The impulsive and convective actions of the liquid are taken into account. The validity of this approach is evaluated by employing a non-linear fluid-structure interaction algorithm of finite element method. Special focus is placed on the boundary conditions imposed from the base isolation and the resulting hydrodynamic pressures. Both horizontal and vertical component of ground motion are considered in order to study the principal effects of the base isolation on the pressure distribution of the tank walls. The induced rocking effects associated with elastomeric bearings are discussed.

A significant reduction of the seismically induced loads can be obtained by the application of base isolation systems, which have to be designed carefully with respect to the modified hydrodynamic behaviour of the tank in interaction with the liquid. For this reason a highly sophisticated fluid-structure interaction model has to be applied for a realistic simulation of the overall dynamic system. In the following, such a model is presented and compared with the results of simplified mathematical models for rigidly supported tanks. Finally, it is examined to what extent a simple mechanical model can represent the behaviour of a base isolated tank in case of seismic excitation}, language = {en} } @inproceedings{RothMoehringTippkoetter2016, author = {Roth, J. and M{\"o}hring, S. and Tippk{\"o}tter, Nils}, title = {Characterization and evaluation of lignocellulosic biomass 130 hydrolysates for ABE fermentation}, series = {New frontiers of biotech-processes (Himmelfahrtstagung) : 02-04 May 2016, Rhein-Mosel-Halle, Koblenz/Germany}, booktitle = {New frontiers of biotech-processes (Himmelfahrtstagung) : 02-04 May 2016, Rhein-Mosel-Halle, Koblenz/Germany}, publisher = {DECHEMA}, address = {Frankfurt am Main}, pages = {130}, year = {2016}, language = {en} } @inproceedings{RousseauKern2014, author = {Rousseau, Alain and Kern, Alexander}, title = {How to deal with environmental risk in IEC 62305-2}, series = {2014 International Conference on Lightning Protection (ICLP), Shanghai, China}, booktitle = {2014 International Conference on Lightning Protection (ICLP), Shanghai, China}, organization = {International Conference on Lightning Protection <2014, Shanghai>}, pages = {521 -- 527}, year = {2014}, abstract = {The 2nd edition of the lightning risk management standard (IEC 62305-2) considers structures, which may endanger environment. In these cases, the loss is not limited to the structure itself, which is valid for usual structures. In the past (Edition 1) this danger was simply taken into account by a special hazard factor, multiplying the existing risk for the structure with a number. Now, in the edition 2, we add to the risk for the structure itself a "second risk" due to the losses outside the structure. The losses outside can be treated independently from what occurs inside. This is a major advantage to analyze the risk for sensitive structures, like chemical plants, nuclear plants, or structures containing explosives, etc. In this paper, the existing procedure given by the European version EN 62305-2 Ed.2 is further developed and applied to a few structures.}, language = {en} } @inproceedings{RuettersWeinheimerBragard2018, author = {R{\"u}tters, Ren{\´e} and Weinheimer, Marius and Bragard, Michael}, title = {Teaching Control Theory with a Simplified Helicopter Model and a Classroom Fitting Hardware Test-Bench}, series = {2018 IEEE 59th International Scientific Conference on Power and Electrical Engineering of Riga Technical University (RTUCON)}, booktitle = {2018 IEEE 59th International Scientific Conference on Power and Electrical Engineering of Riga Technical University (RTUCON)}, isbn = {978-1-5386-6903-7}, doi = {10.1109/RTUCON.2018.8659871}, year = {2018}, language = {en} } @inproceedings{SadeghfamSadeghiAhangarElgamaletal.2019, author = {Sadeghfam, Arash and Sadeghi-Ahangar, A. and Elgamal, Abdelrahman and Heuermann, Holger}, title = {Design and Development of a Novel Self-Igniting Microwave Plasma Jet for Industrial Applications}, series = {IEEE MTT-S International Microwave Symposium Digest}, booktitle = {IEEE MTT-S International Microwave Symposium Digest}, isbn = {978-172811309-8}, pages = {63 -- 66}, year = {2019}, language = {en} } @inproceedings{SajatovicRihacekHaindletal.2007, author = {Sajatovic, Miodrag and Rihacek, Christoph and Haindl, Bernhard and Schnell, Michael and Brandes, Sinja and Gligorevic, Snjezana}, title = {Broadband VHF (B-VHF) project achievements and follow-on activities}, series = {Integrated Communications, Navigation and Surveillance Conference : Herndon, VA, 1 - 3 May 2007}, booktitle = {Integrated Communications, Navigation and Surveillance Conference : Herndon, VA, 1 - 3 May 2007}, organization = {Institute of Electrical and Electronics Engineers}, isbn = {1-4244-1216-1}, pages = {1 -- 8}, year = {2007}, language = {en} } @inproceedings{SattlerAttiAlexopoulosetal.2022, author = {Sattler, Johannes Christoph and Atti, Vikrama and Alexopoulos, Spiros and Teixeira Boura, Cristiano Jos{\´e} and Herrmann, Ulf and Dutta, Siddharth and Kioutsioukis, Ioannis}, title = {DNI forecast tool for the smart operation of a parabolic trough collector system with concrete thermal energy storage: Theory, results and outlook}, series = {SolarPACES conference proceedings}, booktitle = {SolarPACES conference proceedings}, number = {VOL. 1}, publisher = {TIB Open Publishing}, address = {Hannover}, issn = {2751-9899 (online)}, doi = {10.52825/solarpaces.v1i.731}, pages = {9 Seiten}, year = {2022}, abstract = {This work presents a basic forecast tool for predicting direct normal irradiance (DNI) in hourly resolution, which the Solar-Institut J{\"u}lich (SIJ) is developing within a research project. The DNI forecast data shall be used for a parabolic trough collector (PTC) system with a concrete thermal energy storage (C-TES) located at the company KEAN Soft Drinks Ltd in Limassol, Cyprus. On a daily basis, 24-hour DNI prediction data in hourly resolution shall be automatically produced using free or very low-cost weather forecast data as input. The purpose of the DNI forecast tool is to automatically transfer the DNI forecast data on a daily basis to a main control unit (MCU). The MCU automatically makes a smart decision on the operation mode of the PTC system such as steam production mode and/or C-TES charging mode. The DNI forecast tool was evaluated using historical data of measured DNI from an on-site weather station, which was compared to the DNI forecast data. The DNI forecast tool was tested using data from 56 days between January and March 2022, which included days with a strong variation in DNI due to cloud passages. For the evaluation of the DNI forecast reliability, three categories were created and the forecast data was sorted accordingly. The result was that the DNI forecast tool has a reliability of 71.4 \% based on the tested days. The result fulfils SIJ's aim to achieve a reliability of around 70 \%, but SIJ aims to still improve the DNI forecast quality.}, language = {en} } @inproceedings{SattlerSchneiderAngeleetal.2022, author = {Sattler, Johannes Christoph and Schneider, Iesse Peer and Angele, Florian and Atti, Vikrama and Teixeira Boura, Cristiano Jos{\´e} and Herrmann, Ulf}, title = {Development of heliostat field calibration methods: Theory and experimental test results}, series = {SolarPACES conference proceedings}, booktitle = {SolarPACES conference proceedings}, number = {Vol. 1}, publisher = {TIB Open Publishing}, address = {Hannover}, issn = {2751-9899 (online)}, doi = {10.52825/solarpaces.v1i.678}, pages = {9 Seiten}, year = {2022}, abstract = {In this work, three patent pending calibration methods for heliostat fields of central receiver systems (CRS) developed by the Solar-Institut J{\"u}lich (SIJ) of the FH Aachen University of Applied Sciences are presented. The calibration methods can either operate in a combined mode or in stand-alone mode. The first calibration method, method A, foresees that a camera matrix is placed into the receiver plane where it is subjected to concentrated solar irradiance during a measurement process. The second calibration method, method B, uses an unmanned aerial vehicle (UAV) such as a quadrocopter to automatically fly into the reflected solar irradiance cross-section of one or more heliostats (two variants of method B were tested). The third calibration method, method C, foresees a stereo central camera or multiple stereo cameras installed e.g. on the solar tower whereby the orientations of the heliostats are calculated from the location detection of spherical red markers attached to the heliostats. The most accurate method is method A which has a mean accuracy of 0.17 mrad. The mean accuracy of method B variant 1 is 1.36 mrad and of variant 2 is 1.73 mrad. Method C has a mean accuracy of 15.07 mrad. For method B there is great potential regarding improving the measurement accuracy. For method C the collected data was not sufficient for determining whether or not there is potential for improving the accuracy.}, language = {en} } @inproceedings{SattlerAlexopoulosCaminosetal.2019, author = {Sattler, Johannes, Christoph and Alexopoulos, Spiros and Caminos, Ricardo Alexander Chico and Mitchell, John C. and Ruiz, Victor C. and Kalogirou, Soteris and Ktistis, Panayiotis K. and Teixeira Boura, Cristiano Jos{\´e} and Herrmann, Ulf}, title = {Dynamic simulation model of a parabolic trough collector system with concrete thermal energy storage for process steam generation}, series = {AIP Conference Proceedings}, volume = {2126}, booktitle = {AIP Conference Proceedings}, issn = {0094243X}, doi = {10.1063/1.5117663}, pages = {150007-1 -- 150007-8}, year = {2019}, language = {en} } @inproceedings{SattlerCaminosUerlingsetal.2020, author = {Sattler, Johannes, Christoph and Caminos, Ricardo Alexander Chico and {\"U}rlings, Nicolas and Dutta, Siddharth and Ruiz, Victor and Kalogirou, Soteris and Ktistis, Panayiotis and Agathokleous, Rafaela and Jung, Christian and Alexopoulos, Spiros and Atti, Vikrama Nagababu and Teixeira Boura, Cristiano Jos{\´e} and Herrmann, Ulf}, title = {Operational experience and behaviour of a parabolic trough collector system with concrete thermal energy storage for process steam generation in Cyprus}, series = {AIP Conference Proceedings}, booktitle = {AIP Conference Proceedings}, number = {2303}, doi = {10.1063/5.0029278}, pages = {140004-1 -- 140004-10}, year = {2020}, language = {en} } @inproceedings{Sauerborn2011, author = {Sauerborn, Markus}, title = {Investigations to the influence of clouds and aerosols to the haze of the sunshape}, series = {SolarPACES 2011 : concentrating solar power and chemical energy systems : 20 - 23 September, 2011, Granada, Spain}, booktitle = {SolarPACES 2011 : concentrating solar power and chemical energy systems : 20 - 23 September, 2011, Granada, Spain}, address = {Granada}, pages = {1 CD-ROM}, year = {2011}, language = {en} } @inproceedings{SauerbornArshadiRohrmoser2012, author = {Sauerborn, Markus and Arshadi, S. and Rohrmoser, R.}, title = {Influence of clouds and aerosols to the haze of the sunshape}, series = {30th ISES Biennial Solar World Congress 2011 : Kassel, Germany, 28 August - 2 September 2011.
