The development of robust and accurate models requires meaningful features that reflect the system’s degradation process, enabling an accurate prediction of the system's HI. Traditionally, the identification of those is supported by one of various feature ranking methods. In literature, feature interdependencies and their transferability across various similar systems are not sufficiently considered in feature selection, exacerbating the challenge of HI prediction posed by the scarcity of data and system diversity in real-world applications. This work addresses this gaps by demonstrating how filter-based feature selection, incorporating failure thresholds and cross correlations, enhances feature selection leading to improved HI prediction. The proposed methodology is applied to a novel dataset* obtained from run-to-failure experiments on geared motors conducted as part of this study, which presents the aforementioned challenges. It is revealed that classical feature selection, consisting of feature ranking only, leaves potential untapped, which is utilized by the proposed selection methodology. It is shown that the proposed feature selection methodology leads to the best result with a RMSE of 0.14 in predicting the HI of a constructive different gearbox, while the features, determined by classical feature selection, lead to a RMSE of 0.19 at best.}}, author = {{Löwen, Alexander and Wissbrock, Peter and Bender, Amelie and Sextro, Walter}}, isbn = {{978-1-936263-40-0}}, journal = {{PHM Society European Conference}}, location = {{Prague}}, number = {{1}}, pages = {{955--964}}, publisher = {{PHM Society}}, title = {{{Filter-based feature selection for prognostics incorporating cross correlations and failure thresholds}}}, doi = {{10.36001/phme.2024.v8i1.4075}}, volume = {{8}}, year = {{2024}}, } @inproceedings{55631, abstract = {{This paper investigates the remaining useful lifetime (RUL) estimation of bearings under dynamic, i.e., time-varying, operating conditions (OC).

The results showed a 98.5% reduction in PV energy curtailment and a 57% reduction in the levelized cost of energy (LCOE) from 0.808 USD/kWh to 0.350 USD/kWh when the electric two-wheeler and portable storage loads were introduced.

Annual revenue could be increased by 135% by incorporating the additional loads.

In contrast, a limited number of mini-grids under community management strive to survive. Although the concept of “sense of ownership” is considered crucial for mini-grid sustainability in developing countries, there is limited theoretical exploration of the factors that drive this concept and its effects on community mini-grid management. This paper assesses the relationship between the sense of ownership among electricity users and the effective management of two solar community-based mini-grids with different sustainability experience. Results A sense of ownership plays a role in establishing the decision-making process of mini-grids among village energy committee members toward sustainable or unsustainable management. The mechanisms behind the sense of ownership among community members toward managing mini-grids are largely expedited by the strong leadership of village energy committee members, community participation in decision-making and resource mobilisation, especially in the preparation, design and implementation phases of mini-grids. Conclusions A sense of ownership is found to influence the effective management of community mini-grids in Tanzania. When designing mini-grid project policies and programs that target respective communities as prospective owners, energy practitioners and policy-makers should consider creating an environment that nurtures a sense of ownership. }}, author = {{Ngoti, Irene F.}}, issn = {{2192-0567}}, journal = {{Energy, Sustainability and Society}}, number = {{1}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{The role of sense of ownership in rural community mini-grid management: qualitative case study from Tanzania}}}, doi = {{10.1186/s13705-024-00496-7}}, volume = {{14}}, year = {{2024}}, } @misc{55359, booktitle = {{MedienPädagogik}}, editor = {{Glawe, Katrin and Kamin, Anna-Maria and Herding, Jana and Büker, Petra}}, issn = {{1424-3636}}, number = {{62}}, title = {{{Lehrer:innenbildung unter der Perspektive von Inklusion und Digitalisierung.

Fracture methods considered encompass the intrinsic cohesive zone model (CZM) using zero-thickness cohesive interface elements (CIEs), the standard phase-field fracture (SPFM) approach, the cohesive phase-field fracture (CPFM) approach, and an innovative hybrid model. The hybrid approach combines the CPFM fracture method with the CZM, specifically applying the CZM within the interface zone. The finite element model studied is characterized by three specific phases: inclusions, matrix, and the interface zone. This case study serves as a potential template for meso- or micro-level simulations involving a variety of composite materials. The thorough assessment of these modeling techniques indicates that the CPFM approach stands out as the most effective computational model, provided that the thickness of the interface zone is not significantly smaller than that of the other phases. In materials like concrete, which contain interfaces within their microstructure, the interface thickness is notably small when compared to other phases. This leads to the hybrid model standing as the most authentic finite element model, utilizing CIEs within the interface to simulate interface debonding. A significant finding from this investigation is that within the CPFM method, for a specific interface thickness, convergence with the hybrid model can be observed. This suggests that the CPFM fracture method could serve as a unified fracture approach for multiphase materials when a specific interfacial thickness is used. In addition, this research provides valuable insights that can advance efforts to fine-tune material microstructures. An investigation of the influence of interfacial material properties, voids, and the spatial arrangement of inclusions shows a pronounced effect of these parameters on the fracture toughness of the material.}}, author = {{Najafi Koopas, Rasoul and Rezaei, Shahed and Rauter, Natalie and Ostwald, Richard and Lammering, Rolf}}, issn = {{2076-3417}}, journal = {{Applied Sciences}}, number = {{1}}, publisher = {{MDPI AG}}, title = {{{Comparative Analysis of Phase-Field and Intrinsic Cohesive Zone Models for Fracture Simulations in Multiphase Materials with Interfaces: Investigation of the Influence of the Microstructure on the Fracture Properties}}}, doi = {{10.3390/app15010160}}, volume = {{15}}, year = {{2024}}, } @inproceedings{58648, author = {{Unruh, Roland and Böcker, Joachim and Schafmeister, Frank}}, booktitle = {{Proceedings of the Energy Conversion Congress & Expo (ECCE Europe)}}, location = {{Darmstadt}}, publisher = {{IEEE}}, title = {{{Experimentally Verified 22 kW, 40 kHz LLC Resonant Converter Design with new Control for a 1 MW Cascaded H-Bridge Converter}}}, doi = {{10.1109/ECCEEurope62508.2024.10751954}}, year = {{2024}}, } @article{57305, author = {{Gräßler, Iris and Pottebaum, Jens and Grewe, Benedikt}}, journal = {{VDI Konstruktion}}, pages = {{60--61}}, title = {{{Forschen für die Zukunft der Produktentstehung.
