Mesoporous copper–ceria (Cu–CeO2) materials with large specific surface areas and uniform porosity are prepared by nanocasting, and their textural properties are characterized by N2 physisorption, powder XRD, scanning electron microscopy, transmission electron microscopy, and energy-dispersive X-ray spectroscopy. The oxidation states of copper (Cu+, Cu2+) and cerium (Ce3+, Ce4+) are investigated by XPS. The materials are used as resistive gas sensors for H2 and CO. The sensors show a stronger response to CO than to H2 and low cross-sensitivity to humidity. Copper turns out to be a necessary component; copper-free ceria materials prepared by the same method show only poor sensing performance. By measuring both gases (CO and H2) simultaneously, it is shown that this behavior can be utilized for selective sensing of CO in the presence of H2.","lang":"eng"}],"publication":"ACS Sensors","keyword":["Fluid Flow and Transfer Processes","Process Chemistry and Technology","Instrumentation","Bioengineering"],"language":[{"iso":"eng"}]},{"project":[{"grant_number":"418701707","name":"TRR 285: TRR 285","_id":"130"},{"_id":"133","name":"TRR 285 - C: TRR 285 - Project Area C"},{"name":"TRR 285 – C01: TRR 285 - Subproject C01","_id":"145"}],"_id":"34223","user_id":"7850","article_number":"4962","keyword":["Fluid Flow and Transfer Processes","Computer Science Applications","Process Chemistry and Technology","General Engineering","Instrumentation","General Materials Science"],"language":[{"iso":"eng"}],"type":"journal_article","publication":"Applied Sciences","abstract":[{"lang":"eng","text":"In this study, quasi-unidirectional continuous fiber reinforced thermoplastics (CFRTs) are joined with metal sheets via cold formed cylindrical, elliptical and polygonal pin structures which are directly pressed into the CFRT component after local infrared heating. In comparison to already available studies, the unique novelty is the use of non-rotational symmetric pin structures for the CFRT/metal hybrid joining. Thus, a variation in the fiber orientation in the CFRT component as well as a variation in the non-rotational symmetric pins’ orientation in relation to the sample orientation is conducted. The created samples are consequently mechanically tested via single lap shear experiments in a quasi-static state. Finally, the failure behavior of the single lap shear samples is investigated with the help of microscopic images and detailed photographs. In the single lap shear tests, it could be shown that non-rotational symmetric pin structures lead to an increase in maximum testing forces of up to 74% when compared to cylindrical pins. However, when normalized to the pin foot print related joint strength, only one polygonal pin variation showed increased joint strength in comparison to cylindrical pin structures. The investigation of the failure behavior showed two distinct failure modes. The first failure mode was failure of the CFRT component due to an exceedance of the maximum bearing strength of the pin-hole leading to significant damage in the CFRT component. The second failure mode was pin-deflection due to the applied testing load and a subsequent pin extraction from the CFRT component resulting in significantly less visible damage in the CFRT component. Generally, CFRT failure is more likely with a fiber orientation of 0° in relation to the load direction while pin extraction typically occurs with a fiber orientation of 90°. It is assumed that for future investigations, pin structures with an undercutting shape that creates an interlocking joint could counteract the tendency for pin-extraction and consequently lead to increased maximum joint strengths."}],"status":"public","date_updated":"2022-12-05T21:49:30Z","publisher":"MDPI AG","date_created":"2022-12-05T21:48:01Z","author":[{"full_name":"Popp, Julian","last_name":"Popp","first_name":"Julian"},{"first_name":"David","full_name":"Römisch, David","last_name":"Römisch"},{"last_name":"Merklein","full_name":"Merklein, Marion","first_name":"Marion"},{"first_name":"Dietmar","last_name":"Drummer","full_name":"Drummer, Dietmar"}],"volume":12,"title":"Joining of CFRT/Steel Hybrid Parts via Direct Pressing of Cold Formed Non-Rotational Symmetric Pin Structures","doi":"10.3390/app12104962","publication_status":"published","publication_identifier":{"issn":["2076-3417"]},"issue":"10","year":"2022","citation":{"ama":"Popp J, Römisch D, Merklein M, Drummer D.

As piezoelectric elements transform electrical to mechanical energy and vice versa, equivalent circuit modeling is also described. After that, sample applications are delineated by the matter wherein ultrasound generates unique effects: incredible high pressure level as well in air as in water, micro-bubbles generating temperature peaks for very short time instances in fluids, acoustoplastic effect, enhancement of diffusion and recrystallization in solids, friction manipulation, incremental deformation and micro-cracking of surfaces, or even generation of macroscopic movements in motors.

Adapcrack3D is a simulation program that can accurately predict the propagation of cracks in real structures. However, until now, this three-dimensional program has only considered mechanical loads and static thermal loads. Therefore, the features of Adapcrack3D have been extended by including contact loading in crack growth simulations. The numerical simulation of crack propagation with Adapcrack3D is generally carried out using FE models of structures provided by the user. For simulating models with contact loading situations, Adapcrack3D has been updated to work with FE models containing multiple parts and necessary features such as coupling and surface interactions. Because Adapcrack3D uses the submodel technique for fracture mechanical evaluations, the architecture of the submodel is also modified to simulate models with contact definitions between the crack surfaces. This paper discusses the newly implemented attribute of the program with the help of illustrative examples. The results confirm that the contact simulation in Adapcrack3D is a major step in improving the functionality of the program."}],"date_created":"2022-12-05T21:49:48Z","publisher":"MDPI AG","title":"Further Development of 3D Crack Growth Simulation Program to Include Contact Loading Situations","issue":"15","quality_controlled":"1","year":"2022","department":[{"_id":"143"}],"user_id":"45673","_id":"34224","project":[{"grant_number":"418701707","_id":"130","name":"TRR 285: TRR 285"},{"name":"TRR 285 - B: TRR 285 - Project Area B","_id":"132"},{"_id":"143","name":"TRR 285 – B04: TRR 285 - Subproject B04"}],"article_number":"7557","type":"journal_article","status":"public","volume":12,"author":[{"full_name":"Joy, Tintu David","id":"30821","last_name":"Joy","first_name":"Tintu David"},{"first_name":"Deborah","id":"45673","full_name":"Weiß, Deborah","last_name":"Weiß"},{"last_name":"Schramm","id":"4668","full_name":"Schramm, Britta","first_name":"Britta"},{"last_name":"Kullmer","full_name":"Kullmer, Gunter","id":"291","first_name":"Gunter"}],"date_updated":"2023-04-27T10:13:44Z","doi":"10.3390/app12157557","publication_identifier":{"issn":["2076-3417"]},"publication_status":"published","intvolume":"        12","citation":{"apa":"Joy, T.

Proactive change management of requirement changes yields the potential to handle such changes efficiently. A systematic approach is required for proactive change management to assess and reduce the risk of a requirement change with appropriate effort in industrial application. Within the paper at hand, a novel method for Proactive Management of Requirement Changes (ProMaRC) is presented. It is developed in close collaboration with industry experts and evaluated based on workshops, pilot users’ feedback, three industrial case studies from the automotive industry and five development projects from research. To limit the application effort, an automated approach for dependency analysis based on the machine learning technique BERT and semi-automated assessment of change likelihood and impact using a modified PageRank algorithm is developed. Applying the method, the risks of requirement changes are assessed systematically and reduced by means of proactive change measures. Evaluation shows high performance of dependency analysis and confirms the applicability and usefulness of the method. This contribution opens up the research space of proactive risk management for requirement changes which is currently almost unexploited. It enables more efficient product development.</jats:p>","lang":"eng"}],"publication":"Applied Sciences","keyword":["Fluid Flow and Transfer Processes","Computer Science Applications","Process Chemistry and Technology","General Engineering","Instrumentation","General Materials Science"],"language":[{"iso":"eng"}],"year":"2022","quality_controlled":"1","issue":"4","title":"Proactive Management of Requirement Changes in the Development of Complex Technical Systems","publisher":"MDPI AG","date_created":"2022-03-08T12:37:42Z","status":"public","type":"journal_article","article_number":"1874","_id":"30213","user_id":"5905","department":[{"_id":"152"}],"citation":{"apa":"Gräßler, I., Oleff, C., &#38; Preuß, D.

The literature thus far acknowledges that unobservable internal firm characteristics are at least as important as observable firm- and deal-specific characteristics in regard to explaining M&A success. Thus, this paper directly asks M&A experts around the globe to shed more light on this important issue. We investigate three indices, capturing the degree of M&A 1) process standardization, 2) process duration, and 3) process attention. Next, we analyze the process participation among four organizational layers, i.e., the functional involvement of the a) top management team, b) headquarters, c) business unit management, and d) business unit functions. We predict and find that all three indices are positively associated with M&A success, while process standardization and attention to deal strategy are of particular importance. Turning to the four organizational layers, a textured analysis shows that, for instance, target valuation should be performed by the headquarters functions but not by the top management team or the business unit. Overall, our findings are important to better understand unexplored M&A success drivers and provide directions for future research. Finally, our results might help practitioners adjust their M&A process organization to further improve their M&A success."}],"type":"working_paper"},{"citation":{"bibtex":"@article{Kolb_Savov_2020, title={A Characterization of the Finiteness of Perpetual Integrals of Levy Processes}, volume={26}, DOI={<a href=\"https://doi.org/10.48550/arXiv.1903.03792\">https://doi.org/10.48550/arXiv.1903.03792</a>}, number={2}, journal={Bernoulli}, publisher={Bernoulli Society for Mathematical Statistics and Probability}, author={Kolb, Martin and Savov, Mladen}, year={2020}, pages={1453–1472} }","mla":"Kolb, Martin, and Mladen Savov. “A Characterization of the Finiteness of Perpetual Integrals of Levy Processes.” <i>Bernoulli</i>, vol. 26, no. 2, Bernoulli Society for Mathematical Statistics and Probability, 2020, pp. 1453–72, doi:<a href=\"https://doi.org/10.48550/arXiv.1903.03792\">https://doi.org/10.48550/arXiv.1903.03792</a>.","short":"M.

Whether this phenomenon is purely based on an increase of the processing rate of the attended stimulus or if a decrease in the processing rate of the unattended stimulus also contributes to the effect is, up to now, unanswered. Here we describe a novel approach to this question based on Bundesen’s Theory of Visual Attention, which we use to overcome the limitations of earlier prior-entry assessment with temporal order judgments (TOJs) that only allow relative statements regarding the processing speed of attended and unattended stimuli. Prevalent models of prior entry in TOJs either indirectly predict a pure acceleration or cannot model the difference between acceleration and deceleration.

Although most obvious biases have already been excluded experimentally (e.g. judgment criteria, response compatibility) and prior-entry effects have shown to persist (Shore, Spence, & Klein, 2001), many other biases are conceivable, which makes it difficult to put the debate to an end. Thus, we approach this problem the other way around by asking whether prior-entry effects can be biased voluntarily. Observers were informed about prior entry and instructed to reduce it as far as possible.

In Experiment 1, we showed that a spatial misperception, the flash-lag effect, is accompanied by a similar temporal misperception of first perceiving the flash and only then a change of the moving stimulus, when in fact the two events were exactly simultaneous. In Experiment 2, we demonstrated that when the spatial misperception of a flash-lag effect is absent, the temporal misperception is also absent. In Experiment 3, we extended these findings and showed that if the stimulus conditions require coding first a flash and subsequently a nearby moving stimulus, a spatial flash-lag effect is found, with the position of the moving stimulus being misperceived as shifted in the direction of its motion, whereas this spatial misperception is reversed so that the moving stimulus is misperceived as shifted in a direction opposite to its motion when the c"}],"status":"public","publication":"Attention, Perception, & Psychophysics","type":"journal_article","title":"Spatial mislocalization as a consequence of sequential coding of stimuli.","date_updated":"2022-06-06T16:38:04Z","volume":74,"date_created":"2018-12-10T07:07:08Z","author":[{"first_name":"Heinz-Werner","last_name":"Priess","full_name":"Priess, Heinz-Werner"},{"first_name":"Ingrid","last_name":"Scharlau","orcid":"0000-0003-2364-9489","full_name":"Scharlau, Ingrid","id":"451"},{"last_name":"Becker","full_name":"Becker, Stefanie I.","first_name":"Stefanie I."},{"full_name":"Ansorge, Ulrich","last_name":"Ansorge","first_name":"Ulrich"}],"year":"2012","page":"365 - 378","intvolume":"        74","citation":{"ama":"Priess H-W, Scharlau I, Becker SI, Ansorge U.
