During the entire harvesting, every stalk is cut at least one time. For other agricultural processes, such as grain crop harvesting or mulching of brownfields, cutting processes belong also to the main techniques. They have a significant influence on the efficiency and profitability of agricultural machines. Minimizing wear has a high level of importance regarding an environmental friendly and resource efficient agriculture. Wear during agricultural cutting processes is mainly caused due to abrasion and impact stress. Blunt and deformed blades affect the energy efficiency and the cutting quality. The increase of fuel consumption and frequent machine breakdowns with an involvement of high labor and material costs generate considerable economic losses. A consequent, methodical optimization of the wear behavior of the blades can offer a high saving potential of ecological and economic resources. The blade geometry, base material and heat respectively surface treatment substantially determine the wear resistance. Under technological and economic considerations these parameters have to be optimized. Therefore, a test method has been developed at the FMDauto in cooperation with the Ennepetaler Schneid- und M{\"a}htechnik (ESM) GmbH \& Co KG. The test bench enables to test different blades of agricultural machines under standardized and repeatable conditions. This paper presents the test bench and the results of several wear tests. The examinations of the abrasive wear and the impact stress on cutter blades are shown. Algorithms developed at FMDauto are used to analyze the results. It is carried out that further developments of the analyzing methods to describe the sharpness and disruptions of cutter blades are reasonable.}, language = {en} } @misc{OPUS4-6021, title = {1043 - Satzung der Ethikkommission der Hochschule D{\"u}sseldorf f{\"u}r zivile und nicht-invasive Forschung vom 29.01.2026}, address = {D{\"u}sseldorf}, organization = {Hochschule D{\"u}sseldorf}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-60216}, pages = {7}, year = {2026}, abstract = {Aufgrund der \S\S 2 Abs. 4 S. 1, 22 Abs. 1 S. 1 Nr. 3, 4 Abs. 4 S. 3 des Gesetzes {\"u}ber die Hochschulen des Landes Nordrhein-Westfalen (Hochschulgesetz - HG) vom 16.09.2014 (GV.

Using CuO-H2O nanofluid in a bottom-heated channel with circular expansion, we examine the complex interactions between forced convection, magnetic fields, and uoyancy effects. Through systematic numerical analysis, we explore the combined influences of Rayleigh, Reynolds, and Hartmann numbers on thermal performance. Our findings reveal significant heat transfer enhancement (up to 137 \%) under optimal conditions, particularly with vertical magnetic field orientation at Re = 100 and Ha = 30. The results demonstrate how adiabatic blocks modify flow structures, with larger blocks diminishing vortex intensity while elevated Ra generates secondary vortices that interact with primary circulations. Magnetic field effects show notable dependence on orientation, with vertical fields generally promoting better heat transfer than horizontal configurations. To complement the numerical analysis, we develop a predictive model using Artificial Neural Network (ANN) for Nusselt numbers across various operating conditions, achieving over 99 \% accuracy. The integrated computational-ANN approach offers significant advancements in optimizing thermal systems in various areas, ranging from electronics cooling to microfluidic devices.}, language = {en} } @inproceedings{HuesenvonBergSteffens2025, author = {H{\"u}sen, Jonsa and von Berg, Markus and Steffens, Jochen}, title = {Evaluating the Effectiveness of Virtual Listening Tests for Balanced Armature Headphone Drivers}, series = {AES International Conference on Headphone Technology 2025 August 27-29, Espoo, Finland}, booktitle = {AES International Conference on Headphone Technology 2025 August 27-29, Espoo, Finland}, number = {3}, publisher = {Audio Engineering Society}, year = {2025}, language = {en} } @inproceedings{TriebusDruzeticVogelGeiger2025, author = {Triebus, Charlotte and Druzetic-Vogel, Ivana and Geiger, Christian}, title = {Precious Camouflage - Artistic Research for the Creation of a Dance Piece with Humans and AI}, series = {Proceedings of the Conference on Animation and Interactive Art}, booktitle = {Proceedings of the Conference on Animation and Interactive Art}, publisher = {ACM}, address = {New York, NY, USA}, isbn = {979-8-4007-1532-7}, doi = {10.1145/3749893.3749964}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-60099}, pages = {188 -- 198}, year = {2025}, language = {en} } @inproceedings{GeigerAliDilchert2025, author = {Geiger, Christian and Ali, Soren and Dilchert, Philipp}, title = {The BildKlangPoet - a Framework for Designing Mixed Reality Painting Experiences Using Generative AI}, series = {Proceedings of the 22nd International Conference on Culture and Computer Science: Remixing Analog and Digital (KUI '25), September 25, 26, 2025, Berlin, Germany}, booktitle = {Proceedings of the 22nd International Conference on Culture and Computer Science: Remixing Analog and Digital (KUI '25), September 25, 26, 2025, Berlin, Germany}, editor = {Olivero, Lucas Fabian and Stark, Maja and Sch{\"u}rrer, Dagmar and Israel, Johann Habakuk}, publisher = {ACM}, address = {New York, NY, USA}, isbn = {979-8-4007-1478-8/2025/09}, doi = {10.1145/3769526.3769653}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-60086}, pages = {1 -- 4}, year = {2025}, language = {en} } @inproceedings{JahrCorvesBatosetal.2008, author = {Jahr, Andreas and Corves, B. and Batos, Andrej and Wenzel, O.}, title = {Abbildung und Analyse von Schnittprozessen mit Hilfe der Mehrk{\"o}rper- und Str{\"o}mungssimulation - Modellierung eines Mehrk{\"o}rper-Teilungsprozesses und Ermittlung der erforderlichen Antriebsleistung eines H{\"a}ckslers}, series = {Landtechnik regional und international: Land-Technik 2008, Tagung Stuttgart-Hohenheim, 25. und 26.

Cutting tools in agricultureare exposed to a high amount of abrasive wear and impact stress. Increasing the wear resistance of cuttings tools has a highsignificance for the efficiency and profitability of agricultural machinery. Blunt and deformed blades decrease the energy efficiencyand the cutting quality. Blade failures cause machine breakdowns and increase labor and material costs. To enable a consistent andsystematic optimization of the blades, a suitable testing method is necessary. Conventional field tests do not provide comparableand repeatable results. Therefore, a test method developed at the FMDauto in cooperation with the Ennepetaler Schneid- undM¨ahtechnik (ESM) GmbH \& Co. KG is presented. The test bench provides standardized and repeatable conditions with a similarwear pattern which is found during field operations. One of the remaining challenges is a clear wear characterization.

Zum einen ist das eine experimentelle Untersuchung des Verhaltens eines realen schwingungsf{\"a}higen mechanischen Systems. Das Ziel ist das Erstellen eines plausiblen numerischen Prozess- bzw. System-Modells durch Ermittlung der relevanten Systemeinfluss- und Ausgangsgr{\"o}ßen. Zum anderen sind das die Untersuchungen und die Optimierungsmaßnahmen an diesem Modell, um gew{\"u}nschte Systemeigenschaften bzw. Funktionalit{\"a}ten mithilfe eines Optimierungsverfahrens mit anschließender experimenteller Verifikation der Optimierungsergebnisse zu erreichen. Die angestrebten Systemfunktionalit{\"a}ten lassen sich dabei wie folgt formulieren: Die Messeinrichtung des Reglers eines Linearschwingf{\"o}rderers f{\"u}r Sch{\"u}ttgut soll, mit Hilfe des wiegenden Sensors (Kraftsensor) alleine, bei einem kontinuierlichen Materialfluss den Massenstrom, also sowohl die Masse als auch die Geschwindigkeit des auf dem F{\"o}rderorgan der F{\"o}rderanlage bewegenden Gutes, ermitteln. Hierbei wird von einer sensorlosen Erfassung der Geschwindigkeit des F{\"o}rdergutes gesprochen. Die Idee zur sensorlosen Erfassung der Geschwindigkeit eines konstanten Materialflusses am Linearschwingf{\"o}rderer beruht auf der Auswertung des Zeitsignals des im Systemregler integrierten wiegenden Sensors. Das Zeitsignal im sonst konstanten Signal kommt an dem Sensor aufgrund einer Massendiskontinuit{\"a}t (Massenfehler) zustande, die zu diesem Zweck im homogenen Materialfluss auf dem F{\"o}rderorgan (F{\"o}rderrinne) des F{\"o}rderers absichtlich verursacht wird. Die Erzeugung des Massenfehlers wurden {\"u}ber die Variation des Schwingungsverhaltens der F{\"o}rderanlage realisiert. Daf{\"u}r wurden folgende Ph{\"a}nomena in einem mit Vibration belasteten Sch{\"u}ttgut ausgenutzt: Infolge der Ver{\"a}nderung der zugef{\"u}hrten Schwingungsenergie k{\"o}nnen sich sowohl das Profil des Materialstroms als auch die Dichte (Aggregatzustand1) des zu f{\"o}rdernden Materials ver{\"a}ndern. Die Systemantwort auf Variation der Schwingungsenergie in Form des Zeitsignals des wiegenden Sensors wurde mit einem speziellen Auswertungsalgorithmus zur F{\"o}rdergeschwindigkeit ausgewertet. Die Auswertungsergebnisse fließen neben den Werten der Eingangsparameter des Prozesses in das mathematische Modell ein. Im Folgenden wurde das Modell als ein mehrdimensionales Optimierungsproblem betrachtet und unter Anwendung einer geeigneten Optimierungsmethode zielf{\"u}hrend behandelt.

This is important, since the increasing miniaturization and performance demands for electronic devices have led in a growing need for advanced thermal management systems capable of handling rapid transient loads. The novelty of the work lies in examining different heat sink layouts that optimize the heat dissipation capabilities of GR42 PCMs while minimizing size and weight for electronic cooling. The experimental testing was conducted using three configurations, namely no fin, circular fin and hexagonal fin, with three input powers (4 W, 8 W, and 12 W). The experimental results show that the hexagonal-fin heat sink, surface area is 25 \% more than circular fins, exhibited superior thermal performance without significant variation in input power. Notably, the hexagonal-fin heat sink achieved the desired set point temperature of 55 ◦C in 33 \% less time than the circular-fin design and 45 \% less time than the heat sink without fins. Furthermore, the peak temperatures increased up to 21 \% for circular fins. During the charging cycles, the enhancement ratios vary from 72 \% and begin to narrow to 25 \% during discharge cycles. The hexagonal-fin configuration also exhibited superior melting dynamics, completing the phase transition 44 \% faster at higher input power than the circular fins, and established a thermal deviation of nearly 51 \% less than finless heat sinks. These findings underscore the critical role of fin geometry and PCM integration in achieving uniform temperature distribution and improved energy storage efficiency. Overall, the hexagonal-fin heat sink with GR42 PCM shows strong potential as a passive cooling solution for low-power portable electronic devices.}, language = {en} } @misc{Virchow2025, author = {Virchow, Fabian}, title = {Vaughan, Antonia; Braune, John; Tinsely, Meghan \& Mondon, Aurelien (Hrsg.).

The test was based on six acoustic scenes highlighting specific acoustic phenomena and for three complex, "real-world" spatial environments. The results demonstrate that most present simulation algorithms generate obvious model errors once the assumptions of geometrical acoustics are no longer met. As a consequence, they are neither able to provide a reliable pattern of early reflections nor do they provide a reliable prediction of room acoustic parameters outside a medium frequency range. In the perceptual domain, the algorithms under test could generate mostly plausible but not authentic auralizations, i.e., the difference between simulated and measured impulse responses of the same scene was always clearly audible. Most relevant for this perceptual difference are deviations in tone color and source position between measurement and simulation, which to a large extent can be traced back to the simplified use of random incidence absorption and scattering coefficients and shortcomings in the simulation of early reflections due to the missing or insufficient modeling of diffraction.}, language = {en} } @article{AckermannBrinkmannZotteretal.2021, author = {Ackermann, David and Brinkmann, Fabian and Zotter, Franz and Kob, Malte and Weinzierl, Stefan}, title = {Comparative Evaluation of Interpolation Methods for the Directivity of Musical Instruments}, series = {EURASIP Journal on Audio, Speech, and Music Processing}, volume = {2021}, journal = {EURASIP Journal on Audio, Speech, and Music Processing}, number = {1}, publisher = {Springer Nature}, issn = {1687-4722}, doi = {10.1186/s13636-021-00223-6}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-58992}, year = {2021}, abstract = {Measurements of the directivity of acoustic sound sources must be interpolated in almost all cases, either for spatial upsampling to higher resolution representations of the data, for spatial resampling to another sampling grid, or for use in simulations of sound propagation.

Therefore, we evaluated three established approaches for interpolation from a low-resolution sampling grid using high-resolution measurements of a representative sample of musical instruments as a reference. The smallest global error on average occurs for thin plate pseudo-spline interpolation. For interpolation based on spherical harmonics (SH) decomposition, the SH order and the spatial sampling scheme applied have a strong and difficult to predict influence on the quality of the interpolation. The piece-wise linear, spherical triangular interpolation provides almost as good results as the first-order spline approach, albeit with on average 20 times higher computational effort.

From an acoustical point of view, the directivity of musical instruments is relevant both for the loudness and timbre of an instrument at a certain position in the audience, as well as for the spatial characteristics of the generated sound field. Musical instruments, however, are dynamic sound sources always moved by musicians as an element of their performance on stage. This work aims at assessing the acoustical effect and the perceptual relevance of these movements. For this purpose, we have recorded solo musical performances with all standard orchestral instruments with an optical motion tracking system, as well as the corresponding audio signals. The effect of the movements was evaluated by analysing the spectral fluctuation and the time-dependence of room acoustical parameters in a virtual acoustic environment in anechoic and reverberant conditions. In a subsequent listening test, an auralization of the static and dynamic musical performance was presented to listeners by binaural synthesis, showing that the signal-related fluctuations are clearly audible both in anechoic and reverberant situations. We discuss different approaches how to consider these effects for the simulation of natural acoustic sources in virtual acoustic reality.}, language = {en} } @article{AckermannFiedlerBrinkmannetal.2020, author = {Ackermann, David and Fiedler, Felicitas and Brinkmann, Fabian and Schneider, Martin and Weinzierl, Stefan}, title = {On the Acoustic Qualities of Dynamic Pseudo-Binaural Recordings}, series = {Journal of the Audio Engineering Society}, volume = {68}, journal = {Journal of the Audio Engineering Society}, number = {6}, publisher = {Audio-Engineering Society}, issn = {0004-7554}, doi = {10.17743/jaes.2020.0036}, pages = {418 -- 427}, year = {2020}, abstract = {The motion-tracked binaural (MTB) technique allows the dynamic, pseudobinaural rendering of spatial sound scenes recorded by a circular array of microphones on a rigid sphere. The system provides a multichannel live audio transmission from which a head-related signal with approximated interaural time and level differences can be derived and played via headphones, head tracking, and a corresponding rendering software. The latter is mainly calculating imperceptible interpolation between channel pairs during head movements. This contribution evaluates the potential of this format for the creation of virtual acoustic envi- ronments. Based on the technical realization of a 16-channel MTB array with omnidirectional diffuse field-corrected electret condenser microphone capsules, the plausibility of 8 and 16-channel recordings was tested against a physical sound source. Furthermore, the sound quality of the pseudobinaural rendering was assessed based on different items of the Spatial Audio Quality Inventory (SAQI) compared to a true dynamic binaural reference. The results show that the overall plausibility of the MTB signal with optimal interpolation is close to the reference.

While static sound sources, such as loudspeakers, have a relatively consistent acoustic footprint, dynamic sources present a multi-faceted set of challenges. Musical instruments, for example, have dynamic radiation patterns. The directivity of these instruments changes not only with frequency, but also with the specific note being played, and with the performer's gestures. These dynamic effects of directivity influences both the perceived loudness and the timbre at a given location within the audience and shapes the spatial characteristics of the sound field produced. This modulation is crucial when recreating authentic acoustic environments, whether in a virtual environment or in real-world architectural designs.

To provide such a recording, the sound field of an 18-channel loudspeaker orchestra fed by anechoic recordings of a chamber orchestra was captured in two rooms with nine different receivers. In addition, impulse responses were recorded for each sound source and receiver. The anechoic audio signals, the full loudspeaker orchestra recordings and all measured impulse responses are available with open access in the SOFA 2.1 (AES69-2022) format.}, language = {en} } @misc{AspoeckBrinkmannAckermannetal.2019, author = {Asp{\"o}ck, Lukas and Brinkmann, Fabian and Ackermann, David and Weinzierl, Stefan and Vorl{\"a}nder, Michael}, title = {BRAS - A Benchmark for Room Acoustical Simulation}, publisher = {TU Berlin}, address = {Berlin}, doi = {10.14279/depositonce-6726.3}, year = {2019}, language = {en} } @article{AckermannBrinkmannWeinzierl2024, author = {Ackermann, David and Brinkmann, Fabian and Weinzierl, Stefan}, title = {Musical instruments as dynamic sound sources}, series = {Journal of the Acoustical Society of America}, volume = {155}, journal = {Journal of the Acoustical Society of America}, publisher = {Acoustical Society of America}, issn = {1520‑8524}, doi = {10.1121/10.0025463}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-58972}, pages = {2302 -- 2313}, year = {2024}, abstract = {Unlike electro-acoustic sound sources, musical instruments have a time-varying, dynamic directivity, due to the note-dependent radiation behavior of the instrument and due to the expressive movements that musicians perform with their instrument. While previous studies have generally examined the directivity of the static, unmoved instrument for specific notes played, we show the individual and combined contributions of these two factors to a temporal modulation of the radiation behavior, based on motion tracking of typical movement patterns for all instruments of a classical symphony orchestra and on the directivity measured for all partials over the entire pitch range of these instruments. The effect of this modulation, which is manifested by changes in timbre and room acoustic excitation, was determined by spectral variations in the free field and under reverberant conditions, as well as by a modulation of room acoustic parameters. Our results show that these effects are well above the just noticeable differences for all musical instruments and all perceptual variables considered. While the effect of motion dominates for brass instruments, string and woodwind instruments exhibit large note-related differences, which should be taken into account in virtual acoustic realities if an auditory liveliness comparable to physical reality is to be achieved.}, language = {en} } @article{AckermannBoehmWeinzierl2017, author = {Ackermann, David and B{\"o}hm, Christoph and Weinzierl, Stefan}, title = {On the numerical simulation of natural acoustic sound sources [Meeting Abstract]}, series = {The Journal of the Acoustical Society of America}, volume = {141}, journal = {The Journal of the Acoustical Society of America}, number = {5_Supplement}, issn = {0001-4966}, doi = {10.1121/1.4989163}, pages = {3997 -- 3997}, year = {2017}, abstract = {A convincing auralization of acoustical scenes does not only require a proper modeling of the sound propagation between source and receiver, but also an appropriate representation of the acoustical source itself. While the properties of electro-acoustic sources can be well represented by advanced loudspeaker formats with high resolution, the complex, time-variant behavior of natural acoustic sources such as speakers, singers or musical instruments is not in any way considered by current techniques for acoustical simulation and auralization. In the talk, we will present measurement results of the sound power and directivity of natural acoustic sound sources and their dependence on pitch and dynamic level, as well as measurements of typical movements of the source during musical performances. We will demonstrate the physical and perceptual relevance of these effects both in the direct field and in room acoustical environments based on a technical and perceptual evaluation, and discuss new approaches to include these effects in numerical simulations.}, language = {en} }
