In general, those solutions utilize model-based or data-driven methods to diagnose the current state or predict future states of monitored technical systems. However, both methods have their advantages and drawbacks. Combining both methods can improve uncertainty consideration and accuracy. Different combination approaches of those hybrid methods exist to exploit synergy effects. The choice of an appropriate approach depends on different requirements and the goal behind the selection of a hybrid approach.\r\n\r\n \r\n\r\nIn this work, the hybrid approach for estimating remaining useful lifetime takes potential uncertainties into account. Therefore, a data-driven estimation of new measurements is integrated within a model-based method. To consider uncertainties within the system, a differentiation between different system behavior is realized throughout diverse states of degradation.\r\n\r\nThe developed hybrid prediction approach bases on a particle filtering method combined with a machine learning method, to estimate the remaining useful lifetime of technical systems. Particle filtering as a Monte Carlo simulation technique is suitable to map and propagate uncertainties. Moreover, it is a state-of-the-art model-based method for predicting remaining useful lifetime of technical systems. To integrate uncertainties a multi-model particle filtering approach is employed. In general, resampling as a part of the particle filtering approach has the potential to lead to an accurate prediction. However, in the case where no future measurements are available, it may increase the uncertainty of the prediction. By estimating new measurements, those uncertainties are reduced within the data-driven part of the approach. Hence, both parts of the hybrid approach strive to account for and reduce uncertainties.\r\n\r\n \r\n\r\nRubber-metal-elements are employed as a use-case to evaluate the developed approach. Rubber-metal-elements, which are used to isolate vibrations in various systems, such as railways, trucks and wind turbines, show various uncertainties in their behavior and their degradation. Those uncertainties are caused by diverse inner and outer factors, such as manufacturing influences and operating conditions. By expert knowledge the influences are described, analyzed and if possible reduced. However, the remaining uncertainties are considered within the hybrid prediction method. Relative temperature is the selected measurand to describe the element’s degradation. In lifetime tests, it is measured as the difference between the element’s temperature and the ambient temperature. Thereby, the influence of the ambient temperature on the element’s temperature is taken into account. Those elements show three typical states of degradation that are identified within the temperature measurements. Depending on the particular state of degradation a new measurement is estimated within the hybrid approach to reduce potential uncertainties.\r\n\r\nFinally, the performance of the developed hybrid method is compared to a model-based method for estimating the remaining useful lifetime of the same elements. Suitable performance indices are implemented to underline the differences between the results."}],"user_id":"54290","main_file_link":[{"url":"https://papers.phmsociety.org/index.php/phme/article/view/2843","open_access":"1"}],"year":"2021","type":"conference","citation":{"short":"A.

Thus, this paper investigates the application of classical time-domain features, features from the medical field and novel features from the highly comparative time-series analysis (HCTSA) package, for the health state estimation of rotating machinery operating under varying conditions. Furthermore, several feature selection methods are investigated to identify features as viable health indicators for the diagnostics and prognostics of technical systems.

However, an increase in model accuracy with state-of-the-art methods, such as deep convolutional neural networks, results in less interpretability and transparency. Due to the ease of implementation, interpretation and transparency to both domain experts and non-experts, a rule-based method is proposed in this paper, for prognostics and health management (PHM) and specifically for diagnostics. The proposed method utilizes the most relevant sensor signals acquired via feature extraction and selection techniques and expert knowledge. As a case study, the presented method is evaluated on data from a real-world quality control set-up provided by the European prognostics and health management society (PHME) at the conference’s 2021 data challenge.

Exploiting their potential for further improvement and development requires a fundamental understanding of their electronic structure. So far, the most commonly used experimental techniques for this purpose have been all-optical spectroscopy methods that, however, are generally averaging in momentum space. Additional information can be gained by angle-resolved photoelectron spectroscopy (ARPES), which measures the electronic structure with momentum resolution. Here we report on the use of extremely low-energy ARPES (photon energy ~ 7 eV) to increase depth sensitivity and access buried QW states, located at 3 nm and 6 nm below the surface of cubic-GaN/AlN and GaAs/AlGaAs heterostructures, respectively. We find that the QW states in cubic-GaN/AlN can indeed be observed, but not their energy dispersion, because of the high surface roughness. The GaAs/AlGaAs QW states, on the other hand, are buried too deep to be detected by extremely low-energy ARPES. Since the sample surface is much flatter, the ARPES spectra of the GaAs/AlGaAs show distinct features in momentum space, which can be reconducted to the band structure of the topmost surface layer of the QW structure. Our results provide important information about the samples’ properties required to perform extremely low-energy ARPES experiments on electronic states buried in semiconductor heterostructures.","lang":"eng"}],"article_type":"original","user_id":"14931","publication":"Scientific Reports","author":[{"last_name":"Hajlaoui","full_name":"Hajlaoui, Mahdi","first_name":"Mahdi"},{"last_name":"Ponzoni","first_name":"Stefano","full_name":"Ponzoni, Stefano"},{"full_name":"Deppe, Michael","first_name":"Michael","last_name":"Deppe"},{"last_name":"Henksmeier","first_name":"Tobias","full_name":"Henksmeier, Tobias"},{"orcid":"0000-0003-1121-3565","full_name":"As, Donat Josef","first_name":"Donat Josef","id":"14","last_name":"As"},{"full_name":"Reuter, Dirk","first_name":"Dirk","id":"37763","last_name":"Reuter"},{"first_name":"Thomas","full_name":"Zentgraf, Thomas","orcid":"0000-0002-8662-1101","last_name":"Zentgraf","id":"30525"},{"last_name":"Springholz","first_name":"Gunther","full_name":"Springholz, Gunther"},{"full_name":"Schneider, Claus Michael","first_name":"Claus Michael","last_name":"Schneider"},{"last_name":"Cramm","first_name":"Stefan","full_name":"Cramm, Stefan"},{"full_name":"Cinchetti, Mirko","first_name":"Mirko","last_name":"Cinchetti"}],"quality_controlled":"1","volume":11,"date_created":"2021-10-01T07:29:15Z","status":"public","date_updated":"2023-10-09T09:15:12Z","doi":"10.1038/s41598-021-98569-6","oa":"1","language":[{"iso":"eng"}],"title":"Extremely low-energy ARPES of quantum well states in cubic-GaN/AlN and GaAs/AlGaAs heterostructures","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"}],"publication_status":"published","publication_identifier":{"issn":["2045-2322"]},"project":[{"name":"TRR 142","grant_number":"231447078","_id":"53"},{"name":"TRR 142 - Project Area A","_id":"54"},{"_id":"65","name":"TRR 142 - Subproject A8","grant_number":"231447078"},{"name":"TRR 142 - Project Area B","_id":"55"},{"_id":"67","name":"TRR 142 - Subproject B2"},{"name":"TRR 142 - Subproject A6","grant_number":"231447078","_id":"63"}]},{"main_file_link":[{"url":"https://arxiv.org/pdf/2106.05627.pdf","open_access":"1"}],"type":"conference","year":"2021","citation":{"chicago":"Boeddeker, Christoph, Frederik Rautenberg, and Reinhold Haeb-Umbach. “A Comparison and Combination of Unsupervised Blind Source Separation Techniques.” In ITG Conference on Speech Communication, 2021.","ama":"Boeddeker C, Rautenberg F, Haeb-Umbach R.
