So wurden verschiedene nickelbasierte Katalysatorsysteme synthetisiert, wobei sich der via Impr{\"a}gnierung hergestellte Ni/Al2O3-Katalysator sowohl aufgrund seiner guten Leistung als auch der praktikablen und reproduzierbaren Herstellung als geeignetes Benchmark-System f{\"u}r weitere Untersuchungen - vor allem im kinetischen Bereich - erwies.

The control component consists of a model predictive control applica-tion (MPC) with a flexible objective function and on-line tunable weights, which runs on a In-dustrial PC and uses a reduced order dynamic model of the receiver's thermal and flow dy-namics. The second component consists of a service-life monitoring unit, which estimates the service-life consumption of the absorber tubes depending on the current mode of operation based on thermal stresses and creep fatigue in the high temperature regime. The calculation of stresses is done based on a detailed finite element study, in which a digital twin of the re-ceiver was developed. By parallelising the model solver, the estimation of service-life con-sumption became capable of real-time operation. The system has been implemented at a test facility in J{\"u}lich, Germany, and awaits field experiments.

Methodology/approach - A systematic literature search of articles in ScienceDirect between 2016 and 2023 is carried out. The keywords are sustainability and system engineering incl. synonyms. In a further step, the papers are screened for their relevance to product service systems and the relevance for the purpose. Findings - To address sustainability in complex technical systems, a holistic, model-based approach is required to ensure that sustainability aspects are considered. By using frameworks and methods such as macPro² and SysLM, requirements and indicators for sustainability can be integrated into the development phase, whereas currently only the environmental dimension is usually considered via resource and energy indicators. Research limitations/implications - In order to achieve a complete picture, additional databases must be considered and research results from ongoing projects must be awaited.}, subject = {Systemtechnik}, language = {en} } @inproceedings{OPUS4-2336, title = {SIMULAND 2020: Simulation landtechnischer Prozesse, D{\"u}sseldorf, 19.

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 research records the current manufacturing quality of the mower blades and examines how they behave in comparison. Based on the obtained results, further decisions on the methods, procedures and ways of extending the life of the disc mower blades should be proposed.

Hence, regression models require high accuracy for the present system state and at the same time need to be valid across the whole system operating space. While accuracy for the current system state can be gained by updating the model on the current data, the overall validity must often be retrieved from historical or design data. We propose a method to find an appropriate compromise for these two demands. A pre-trained artificial neural network (ANN) is continually updated on the current sensor data stream using convex optimisation. Thus, a unique and optimal solution is generated in each update step, while robust regression accuracy on the domain that is not covered by the arriving data subset is maintained. This is achieved by introducing a data management system to provide some historical data, constraining the optimisation problem and manipulating the architecture of the ANN.

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.

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} } @article{JahrCorvesBatosetal.2010, author = {Jahr, Andreas and Corves, Burkhard and Batos, Andrej and Schumacher, Mathias}, title = {Simulation landtechnischer Schnitt- und Str{\"o}mungsprozesse}, series = {agricultural engineering.eu}, volume = {65}, journal = {agricultural engineering.eu}, number = {5}, publisher = {Kuratorium f{\"u}r Technik und Bauwesen in der Landwirtschaft e.

Stripper Header is a new technique different to conventional harvester machines and it is still under development and testing. It works on the principle in which grains are first stripped off from the head of the standing crop which helps in much reduced intake freeing up the separation systems to handle a larger volume of grains. But with this, the new problem of the disposal of the long, uncut straw left after stripping of grains arose. So a straw cutter is used after the stripper header stage in this Combine Harvester, where the rotor is equipped with pressed steel blades and rotates towards the crop, i.e., it cuts and lifts the straw over the top. This technique is environment friendly because previously farmers would have to burn the long, uncut straw standing in the fields while in this case mulched straw can be used for min-till systems. This rotor based straw cutting machine is analysed here which helps us in increasing power efficiency and comminution rate and quality of cut straw particles. Here fluid flow simulation has been preferred over particle simulation: - CFX 10.0 tool is not very effective for particle simulation techniques and computation time is increased considerably. - It's very hard to realize particle simulation in CFX 10.0 because we have to define size and properties of each particle and besides this wall conditions would have to be defined differently for every boundary. - Besides this, it's hard to realize cutting effect with straw particles in CFX 10.0 which otherwise would be comminuted in real life conditions. - The results obtained from fluid simulation are validated using experimental results and found to be nearly the same which clearly contradicts any need of performing particle simulation.}, language = {en} } @techreport{JahrBatosHappel2007, author = {Jahr, Andreas and Batos, Andrej and Happel, Holger}, title = {Modellierung eines Strohhalmes in einem Mehrk{\"o}rpersimulationsprogramm}, address = {D{\"u}sseldorf}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-3624}, pages = {13}, year = {2007}, abstract = {Im Rahmen dieser Ausarbeitung wird gezeigt, wie ein Weizenstrohhalm in dem Mehrk{\"o}rpersimulationsprogramm SIMMECHANICS, das ein Zusatztool des Simulations- und Berechnungsprogramms MATLAB(R) bzw.

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} } @article{SulaimanSaberHasanetal.2026, author = {Sulaiman, Mohammed A. and Saber, Hindren Ali and Hasan, Hasan F. and Benim, Ali Cemal}, title = {Latent heat cold storage integrated direct evaporative cooler: A neoteric practical design for energy and water saving potential with thermal comfort improvement}, series = {Journal of Energy Storage}, volume = {143}, journal = {Journal of Energy Storage}, publisher = {Elsevier}, issn = {2352-152X}, doi = {10.1016/j.est.2025.119612}, pages = {20}, year = {2026}, subject = {Latentw{\"a}rmespeicher}, language = {en} } @incollection{SiekmannSteedMangarooPillayetal.2025, author = {Siekmann, Leonard and Steed, Clint Alex and Mangaroo-Pillay, Mia and Niemann, J{\"o}rg and Fussenecker, Claudia}, title = {Identifying the Industry 4.0 Skills Gap: A Comparative Analysis of Vocational Training in South Africa and Germany}, series = {Advancing Learning Factories: Enabling Future-Ready Skills.

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.

So far, health effects of long-term exposure to ambient ultrafine particles are not well understood, owing to a lack of exposure data and epidemiological studies. Methods We conducted a systematic review and meta-analysis on the health effects of long-term exposure to ultrafine particles, including studies published until December 2024. A meta-analysis was conducted for outcomes with at least four available effect estimates. Confidence in the body of evidence was evaluated using the Office of Health Assessment and Translation method. Results We identified 85 studies investigating various mortality, morbidity and subclinical outcomes. In meta-analyses of single-pollutant models, we found positive associations with natural mortality (hazard ratio 1.06, 95\% CI 1.04-1.08) and C-reactive protein (10.14\% increase (95\% CI -0.51-21.99\%) per 10 000 pt·cm-3 increase in long-term exposure to ultrafine particles, with low and inadequate levels of evidence, respectively. The remaining studies revealed overall limited evidence for adverse effects on a wide range of outcomes. Less than half of the studies adjusted for co-pollutants. Conclusion The evidence base on long-term health effects of ultrafine particles has increased substantially in the past decade, while the overall evidence for independent effects of long-term ultrafine particle exposure remains inadequate to low. More studies are needed to draw firm conclusions about the independent adverse effects of long-term ultrafine particles on various health end-points, with a special focus on the influence of co-pollutant adjustment.}, subject = {Schadstoffbelastung}, language = {en} } @misc{OPUS4-6085, title = {1045 - Vierte Satzung zur {\"A}nderung der Pr{\"u}fungsordnung f{\"u}r den Masterstudiengang „Umweltingenieurwesen" an der Hochschule D{\"u}sseldorf vom 18.02.2026}, address = {D{\"u}sseldorf}, organization = {Hochschule D{\"u}sseldorf}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-60857}, pages = {2}, year = {2026}, abstract = {Aufgrund der \S\S 2 Abs. 4, 64 Abs. 1 des Gesetzes {\"u}ber die Hochschulen des Landes Nordrhein-Westfalen (Hochschulgesetz - HG) vom 16.09.2014 (GV.

With an emphasis on their function in thermal control, this review article offers an in-depth review of PCM applications in electronics, buildings and solar energy systems. PCMs are used in electronics to control device temperatures, which lowers the risk of overheating and increases operational efficiency by 10\% to 25\%. Through latent heat storage and release in reaction to temperature changes, PCMs are incorporated into walls, floors, and roofs in building applications to improve thermal comfort and cut energy use by 15\% to 30\%. By storing thermal energy for steady power generation, PCMs increase the dependability and efficiency of solar energy systems by 8\%-20\%. This review examines the basic ideas behind PCMs, assesses various PCM (such as organic, inorganic, and eutectic PCMs), and details about real-world applications in these energy management fields. Important issues are examined, such as material compatibility, cost-effectiveness, and long-term stability. In order to maximize performance in these crucial applications, the conclusion emphasizes the need for improvements in cost-effective PCM formulations for the improved thermal conductivity (0.2-0.7 W m-1·K-1), and adaptive control systems.}, subject = {Energieeffizienz}, language = {en} } @phdthesis{Muench2026, author = {M{\"u}nch, Justin}, title = {Mehrwert von Methoden des Maschinellen Lernens f{\"u}r die simulative Bewertung der Versorgungssicherheit mit Elektrizit{\"a}t}, publisher = {Hochschule D{\"u}sseldorf}, address = {D{\"u}sseldorf}, doi = {10.20385/opus4-5830}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-58306}, school = {Hochschule D{\"u}sseldorf}, pages = {126}, year = {2026}, abstract = {Politik und Wirtschaft sind auf eine fundierte, schnelle und flexible Bewertung der Ver-sorgungssicherheit mit Elektrizit{\"a}t als Grundlage strategischer Entscheidungen angewiesen.
