However, these tests often target acoustic parameters other than those typically relevant in music such as pitch, rhythm, amplitude, or timbre. To assess the expertise in perceiving and understanding room acoustical phenomena, a listening test battery was constructed to measure the perceptual sensitivity and cognitive abilities in the identification of rooms with different reverberation times and different spectral envelopes. Performance in these tests was related to data from the Goldsmiths Musical Sophistication Index, self-reported previous experience in music recording and acoustics, and academic knowledge on acoustics. The data from 102 participants show that sensory and cognitive abilities are both correlated significantly with musical training, analytic listening skills, recording experience, and academic knowledge on acoustics, whereas general interest in and engagement with music do not show any significant correlations. The regression models, using only significantly correlated criteria of musicality and professional expertise, explain only small to moderate amounts (11\%-28\%) of the variance in the "room acoustic listening expertise" across the different tasks of the battery. Thus, the results suggest that the traditional criteria for selecting expert listeners in room acoustics are only weak predictors of their actual performances.}, language = {en} } @article{HeizmannBraunHuetteletal.2020, author = {Heizmann, Michael and Braun, Alexander and H{\"u}ttel, Markus and Kl{\"u}ver, Christina and Marquardt, Erik and Overdick, Michael and Ulrich, Markus}, title = {Artificial intelligence with neural networks in optical measurement and inspection systems}, series = {at - Automatisierungstechnik}, volume = {68}, journal = {at - Automatisierungstechnik}, number = {6}, publisher = {De Gruyter}, doi = {10.1515/auto-2020-0006}, pages = {477 -- 487}, year = {2020}, language = {en} } @article{PriesmannMuenchTillmannsetal.2024, author = {Priesmann, Jan and M{\"u}nch, Jonas and Tillmanns, Marius and Ridha, E. and Spiegel, T. and Reich, Marius and Adam, Mario and Nolting, L. and Praktiknjo, Aaron}, title = {Artificial intelligence and design of experiments for resource adequacy assessment in power systems}, series = {Energy Strategy Reviews}, volume = {53}, journal = {Energy Strategy Reviews}, publisher = {Elsevier}, issn = {2211-467X}, doi = {10.1016/j.esr.2024.101368}, year = {2024}, language = {en} } @article{PrataDezitterDaviesetal.2016, author = {Prata, A.

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. For the first time, airborne remote detection of volcanic ash has been successfully demonstrated from a long-range flight test aircraft.}, language = {en} } @article{KuniiHerderMyszkowskietal.1994, author = {Kunii, Tosiyasu L. and Herder, Jens and Myszkowski, Karol and Okunev, Oleg and Okuneva, Galina and Ibusuki, Masumi}, title = {Articulation Simulation for an Intelligent Dental Care System}, series = {Displays}, volume = {15}, journal = {Displays}, number = {3}, pages = {181 -- 188}, year = {1994}, abstract = {CAD/CAM techniques are used increasingly in dentistry for design and fabrication of teeth restorations. An important issue is preserving occlusal contacts of teeth after restoration. Traditional techniques based on the use of casts with mechanical articulators require manual adjustment of occlusal surface, which becomes impractical when hard restoration materials like porcelain are used; they are also time and labor consuming. Most existing computer systems ignore completely such an articulation check, or perform the check at the level of a tooth and its immediate neighbors. We present a new mathematical model and a related user interface for global articulation simulation, developed for the Intelligent Dental Care System project. The aim of the simulation is elimination of the use of mechanical articulators and manual adjustment in the process of designing dental restorations and articulation diagnostic. The mathematical model is based upon differential topological modeling of the jawbs considered as a mechanical system. The user interface exploits metaphors that are familiar to dentists from everyday practice. A new input device designed specifically for use with articulation simulation is proposed.}, language = {en} } @inproceedings{FranzAnsgarStaab2009, author = {Franz, Thomas and Ansgar, Scherp and Staab, Steffen}, title = {Are semantic desktops better?}, series = {Proceedings of the Fifth International Conference on Knowledge Capture, September 1 - 4, 2009, Redondo Beach, California, USA}, booktitle = {Proceedings of the Fifth International Conference on Knowledge Capture, September 1 - 4, 2009, Redondo Beach, California, USA}, editor = {Gil, Yolanda}, publisher = {Association for Computing Machinery}, address = {New York, NY}, isbn = {978-1-60558-658-8}, doi = {10.1145/1597735.1597737}, pages = {1 -- 8}, year = {2009}, language = {en} } @inproceedings{DewitzWicheGeigeretal.2018, author = {Dewitz, Bastian and Wiche, Roman and Geiger, Christian and Steinicke, Frank and Feitsch, Jochen}, title = {AR Sound Sandbox: A Playful Interface for Musical and Artistic Expression}, series = {Intelligent Technologies for Interactive Entertainment. 9th International Conference, INTETAIN 2017, Funchal, Portugal, June 20-22, 2017, Proceedings}, booktitle = {Intelligent Technologies for Interactive Entertainment. 9th International Conference, INTETAIN 2017, Funchal, Portugal, June 20-22, 2017, Proceedings}, editor = {Chisik, Yoram and Holopainen, Jussi and Khaled, Rilla and Luis Silva, Jos{\´e} and Alexandra Silva, Paula}, publisher = {Springer International Publishing}, address = {Cham}, isbn = {978-3-319-73061-5}, doi = {10.1007/978-3-319-73062-2_5}, pages = {59 -- 76}, year = {2018}, language = {en} } @inproceedings{RyskeldievCohenHerder2017, author = {Ryskeldiev, Bektur and Cohen, Michael and Herder, Jens}, title = {Applying rotational tracking and photospherical imagery to immersive mobile telepresence and live video streaming groupware}, series = {Proceeding SA '17 SIGGRAPH Asia 2017 Mobile Graphics \& Interactive Applications, Article No. 5}, booktitle = {Proceeding SA '17 SIGGRAPH Asia 2017 Mobile Graphics \& Interactive Applications, Article No. 5}, publisher = {ACM}, address = {New York}, isbn = {978-1-4503-5410-3}, doi = {10.1145/3132787.3132813}, pages = {2}, year = {2017}, abstract = {Mobile live video streaming is becoming an increasingly popular form of interaction both in social media and remote collaboration scenarios.

Road infrastructure has been designed for human vision, so computer vision, with RGB cameras, is a vital source of semantic information from the environment. Sensors, such as LIDAR and RADAR, are also often utilized for these applications; however, cameras provide a higher spatial resolution and color information. The spatial frequency response (SFR), or sharpness of a camera, utilized in object detection systems must be sufficient to allow a detection algorithm to localize objects in the environment over its lifetime reliably. This study explores the relationship between object detection performance and SFR. Six state-of-the-art object detection models are evaluated with varying levels of lens defocus. A novel raw image dataset is created and utilized, containing pedestrians and cars over a range of distances up to 100-m from the sensor. Object detection performance for each defocused dataset is analyzed over a range of distances to determine the minimum SFR necessary in each case. Results show that the relationship between object detection performance and lens blur is much more complex than previous studies have found due to lens field curvature, chromatic aberration, and astigmatisms. We have found that smaller objects are disproportionately impacted by lens blur, and different object detection models have differing levels of robustness to lens blur}, language = {en} } @article{PfeiffelmannOzmanBenimetal.2022, author = {Pfeiffelmann, Bjorn and Ozman, Cansu and Benim, Ali Cemal and Joos, Franz}, title = {Analysis of the effect of nonuniform surface temperature distribution on the performance of a thermoelectric generator}, series = {Sustainable Energy Technologies and Assessments}, volume = {53}, journal = {Sustainable Energy Technologies and Assessments}, number = {A}, publisher = {Elsevier}, issn = {2213-1388}, doi = {10.1016/j.seta.2022.102375}, year = {2022}, language = {en} } @inproceedings{vonBergSchwoererPrinzetal.2023, author = {von Berg, Markus and Schw{\"o}rer, Paul and Prinz, Lukas and Steffens, Jochen}, title = {Analysis of physical and perceptual properties of room impulse responses: development of an online tool}, series = {Forum Acusticuum 2023: 10th Convention of European Acoustics Association, Turin, Italy, 11th-15th September 2023}, booktitle = {Forum Acusticuum 2023: 10th Convention of European Acoustics Association, Turin, Italy, 11th-15th September 2023}, publisher = {EAA}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-41955}, pages = {8}, year = {2023}, abstract = {Over the past decades, research in room acoustics has established several derivative measures of an impulse response, some of which are incorporated in the ISO 3382 standards. These parameters intend to represent perceptual qualities, but were developed without a consistent modeling of room acoustical perception. More recent research proposed comprehensive inventories of room acoustic perception that are purely based on evaluations by human subjects, such as the Room Acoustical Quality Index (RAQI). In this work RA-QI scores acquired for 70 room impulse responses were predicted from room acoustical parameters. Except for Reverberance, the prediction of RAQI factors performed rather poor. In most cases, the sound source had a greater impact on RAQI scores. All analyses are published in an online tool, where users can upload omnidirectional and binaural impulse responses, and instantly obtain and visualize several physical descriptors, as well as predicted RAQI scores for three different sound sources. So far, acceptable prediction accuracy is achieved for Reverberance, Strength, Irregular Decay, Clarity and Intimacy. Larger data sets of evaluated impulse responses are required to improve the model performance and enable reliable predictions of room acoustical quality.

abstract = {Leading edge serrations are well-known for their aeroacoustic potential in reducing aerofoil-turbulence interaction noise and are also associated with certain aerodynamic advantages. To prepare leading edge serrations for industrial application, two obstacles remain to be addressed. First is a combined analysis of the aeroacoustic and the aerodynamic performance of leading edge serrations to develop optimum designs. Second is the need to examine the transferability of the known effects of leading edge serrations from a single aerofoil to full rotors, which are considered to be the final area of application. This thesis aims to assist in the transfer of a well-investigated aerofoil with serrated leading edges from the rigid to the rotating domain. With this purpose, a single aerofoil type is selected and thoroughly analysed, experimentally and numerically, to generate a reliable data basis for aerodynamic performance and noise reduction capability. Aside from gathering information on the overall performance, the spatial distribution of the noise sources is localised, and the spectral composition of the noise reduction is found to follow a clearly defined scaling law. Aerodynamically, generated vortices are found to be responsible for a complex three-dimensional separation mechanism of the leading edge serrations, causing a delay of stall. The generated data basis is then used to design low-pressure axial fans of minimum complexity by keeping the initially chosen aerofoil type. The experimentally identified noise reduction mechanisms for the serrated axial fans are found to be more diverse than the single aerofoil and highly dependent on the inflow conditions and the operation point of the fan. A highly similar pattern for the spectral scaling of the noise reduction supports the finding that at optimum operation conditions, the previously identified noise reduction mechanisms for the single aerofoils are transferable to the rotating domain. On the other hand, additional aerodynamic mechanisms are found to dominate the noise reduction for the instability region of the fan, also contributing to reduced blade-to-blade interaction effects. Moreover, the blade-tip leakage flow is altered by delaying the development of coherent structures. The next step towards a more general description of the aeroacoustic and aerodynamic dependencies is developing a comprehensive model based on artificial neural networks. This model allows a combined analysis of the aerodynamic and acoustic performance of rotors with serrated leading edges and shows an accurate prediction of the overall performance and the spectral composition of the radiated noise. It also enables the development of multi-objective optima for serration designs and motivates further studies into the generalisability of the observed trends. Furthermore, the developed model represents a feasible tool to create tailored serration designs for maximum efficiency in both aeroacoustics and aerodynamics, contributing to the development of future low-noise fans and rotating machinery.}, language = {en} } @article{WinklerBeckerDoolanetal.2012, author = {Winkler, Michael and Becker, Klaus and Doolan, Con and Kameier, Frank and Paschereit, Christian Oliver}, title = {Aeroacoustic Effects of a Cylinder-Plate Configuration}, series = {AIAA Journal}, volume = {50}, journal = {AIAA Journal}, number = {7}, publisher = {ARC}, doi = {10.2514/1.j051578}, pages = {1614 -- 1620}, year = {2012}, language = {en} } @inproceedings{EchternachtHeubergerBreueretal.2013, author = {Echternacht, David and Heuberger, Daniel and Breuer, Christopher and Linnemann, Christian and Moser, Albert}, title = {Advantageous positions for HVDC terminals in Europe}, series = {2013 IEEE Energytech, 21.05.2013 - 23.05.2013, Cleveland}, booktitle = {2013 IEEE Energytech, 21.05.2013 - 23.05.2013, Cleveland}, publisher = {IEEE}, isbn = {978-1-4673-4444-9}, doi = {10.1109/EnergyTech.2013.6645291}, pages = {1 -- 5}, year = {2013}, language = {en} } @article{BeniddirKangGentaJouveetal.2021, author = {Beniddir, Mehdi A. and Kang, Kyo Bin and Genta-Jouve, Gr{\´e}gory and Huber, Florian and Rogers, Simon and van der Hooft, Justin J.

In this contribution a control concept based on Exact I/O-Linearization is proposed and compared to a conventional cascade control structure. In order to adapt the exact linearization control strategy to various polymerization products and batch conditions, an advanced probabilistic inference algorithm (Sigma-Point Kalman Filter) is applied and investigated. Sigma-Point Kalman Filters have the major improvement of simplified implementation compared to local linearization methods (i.e. Extended Kalman Filter) because no analytical Jacobians are required. Stochastic simulation studies are introduced and show the effectiveness, accuracy and benefit of the control concept. Within several scenarios a satisfying robustness against structural errors in the underlying model equations for the nonlinear control law and the inference algorithm is demonstrated.

Although it is known that cytoskeletal coordination is vital for cell function, the mechanisms by which cross-linking proteins coordinate actin and microtubule activities remain poorly understood. In particular, it is unknown how the distinct mechanical properties of different actin architectures modulate the outcome of actin-microtubule interactions. To address this question, we engineered the protein TipAct, which links growing microtubule ends via end-binding proteins to actin filaments. We show that growing microtubules can be captured and guided by stiff actin bundles, leading to global actin-microtubule alignment. Conversely, growing microtubule ends can transport, stretch and bundle individual actin filaments, thereby globally defining actin filament organization. Our results provide a physical basis to understand actin-microtubule cross-talk, and reveal that a simple cross-linker can enable a mechanical feedback between actin and microtubule organization that is relevant to diverse biological contexts.}, language = {en} } @article{SiccardiAdamatzkyTuszyńskietal.2020, author = {Siccardi, Stefano and Adamatzky, Andrew and Tuszyński, Jack and Huber, Florian and Schnauß, J{\"o}rg}, title = {Actin networks voltage circuits}, series = {Physical Review E}, volume = {101}, journal = {Physical Review E}, number = {5-1}, publisher = {American Physical Society (APS)}, issn = {2470-0053}, doi = {10.1103/PhysRevE.101.052314}, year = {2020}, language = {en} } @article{AdamatzkySchnaussHuber2019, author = {Adamatzky, Andrew and Schnauß, J{\"o}rg and Huber, Florian}, title = {Actin droplet machine}, series = {Royal Society Open Science}, volume = {6}, journal = {Royal Society Open Science}, number = {12}, publisher = {Royal Soc.

A Eulerian-Lagrangian formulation is used to describe the two-phase flow. Turbulence is modelled within a RANS (Reynolds averaged numerical simulation) framework. Four turbulence viscosity- (TV) based models, namely the standard k-ε model, realizable k-ε model, renormalization group theory k-ε model, and the shear stress transport k-ω model are used. In addition, a Reynolds stress transport model (RSM) is employed. The models are assessed by comparing the predicted velocity fields with the measurements of other authors. In terms of overall average values, the agreement of the predictions to the measurements is observed to be within the range 20-40\%. A better performance of the RSM compared to the TV models is observed, with a nearly twice as better overall agreement to the experiments, particularly for the swirl velocity. In the second part of the investigation, the resolution of the discrete particle phase in modelling the turbulent particle dispersion (TPD) and particle size distribution (SD) is investigated. Using the discrete random walk model for the TPD, it is shown that even five random walks are sufficient for an accuracy that is quite high, with a less than 1\% mean deviation from the solution obtained by thirty random walks. The approximation of the measured SD is determined by a continuous Rosin-Rammler distribution function, and inaccuracies that can occur in its subsequent discretization are demonstrated and discussed. An investigation on the resolution of the SD by discrete particle size classes (SC) indicates that 12 SC are required for an accuracy with a less than 1\% mean deviation from the solution with 18 SC.

Afterwards, the security problems and the solution approaches are formally modeled in detail. The formal models serve to prove that the solution approaches are correct solutions to the security problems. Furthermore, the formal models of the solution approaches constitute a formal specification of the software to be developed. Then, the specification is implemented by generic security components and generic security architectures, which constitute architectural patterns.

Ground truth tracking systems require markers to create high quality motion data. But in many applications it is desired to work without markers. In recent years affordable hardware for markerless tracking systems was made available at a consumer level. Efficient depth camera systems based on Time-of-Flight sensors and structured light systems have made it possible to record motion data in real time. However, the gap between the quality of marker-based and markerless systems is high. The error sources of a markerless motion tracking pipeline are discussed and a model-based filter is proposed, which adapts depending on spatial location. The proposed method is then proven to be more robust and accurate than the unfiltered data stream and can be used to visually enhance the presence of an actor within a virtual environment in live broadcast productions.}, language = {en} } @techreport{AnsgarScherpThomasFranzCarstenSaathoffetal.2009, author = {Ansgar Scherp, and Thomas Franz, and Carsten Saathoff, and Steffen Staab,}, title = {A Model of Events based on a Foundational Ontology}, series = {Arbeitsberichte aus dem Bereich Informatik}, journal = {Arbeitsberichte aus dem Bereich Informatik}, publisher = {Universit{\"a}t Koblenz-Landau}, address = {Koblenz}, organization = {Universit{\"a}t Koblenz-Landau}, issn = {1864-0850}, year = {2009}, language = {en} } @techreport{KopsKhabyuk2007, author = {Kops, Manfred and Khabyuk, Olexiy}, title = {A methodology for the graphical exposition of broadcasting systems}, volume = {Arbeitspapiere des Instituts f{\"u}r Rundfunk{\"o}konomie an der Universit{\"a}t zu K{\"o}ln}, number = {231e}, publisher = {Inst. f{\"u}r Rundfunk{\"o}konomie, Univ.

This interdisciplinary community is fairly new, it is still not well integrated and is therefore confronted with differing perspectives, processes, methods, tools, vocabularies, and standards. We present a Common Body of Knowledge (CBK) to overcome the aforementioned problems. We capture use cases from research and practice to derive requirements for the CBK. Our CBK collects, integrates, and structures knowledge from the different disciplines based on an ontology that allows one to semantically enrich content to be able to query the CBK. The CBK heavily relies on user participation, making use of the Semantic MediaWiki as a platform to support collaborative writing. The ontology is complemented by a conceptual framework, consisting of concepts to structure the knowledge and to provide access to it, and a means to build a common terminology. We also present organizational factors covering dissemination and quality assurance.}, language = {en} } @incollection{JonesCastroMahmoudetal.2002, author = {Jones, Kevin and Castro, Breno and Mahmoud, Osama and Pollard, S. and Platzer, Max and Neef, Matthias and Gonet, K. and Hummel, D.}, title = {A collaborative numerical and experimental investigation of flapping-wing propulsion}, series = {40th AIAA Aerospace Sciences Meeting \& Exhibit}, booktitle = {40th AIAA Aerospace Sciences Meeting \& Exhibit}, publisher = {American Institute of Aeronautics and Astronautics}, address = {Reston, Virigina}, doi = {10.2514/6.2002-706}, pages = {36}, year = {2002}, abstract = {An international, collaborative investigation is undertaken to evaluate the relative merits and limitations of various numerical methods and experimental measurement techniques, specifically for the analysis of flapping-wing propulsion. A finite aspect-ratio configuration is extensively investigated, both quantitatively and qualitatively, in a low-speed wind tunnel. Direct force measurements are made, as well as time-accurate and time-averaged laser Doppler velocimetry and unsteady flow visualization. The reduced frequency, mean angle of attack, aspect ratio and Reynolds number are varied in the experiments. The experiment is numerically simulated using flatplate theory, two and three-dimensional panel codes, and two and three-dimensional Euler and Navier- Stokes solvers. The ability of each of the methods to capture important aspects of the flow physics are evaluated through comparisons with each other and the experimental data. Additionally, the comparisons indicate areas where further research is needed. The collaborative effort provides a survey of available capabilities and provides a fixed set of flappingwing data for others to compare against.}, language = {en} }
