For enhanced understanding of damage and failure mechanism under thermal shock loading, in the present work, a combination of experimental testing and numerical simulation methods has been used. The thermal shock behavior of the alumina (99.7\%) disk samples has been investigated by using a plasma test stand: the bottom of the ceramic disks were locally heated in the center by plasma beam; during the heat treatment the temperature distribution at the top of the sample was recorded with a thermographic system. To characterize the thermal shock resistance, a thermomechanical simulation was subsequently carried out. It calculates the temperature and stress distribution within the ceramic disks. The calculated critical thermal tension stresses are reported, which led to the failure of the ceramic disks under thermal shock loading. The effect of the sample thickness on the temperature and stress distribution is presented. Compared with the experimental results the simulated results show excellent agreement. As conclusion, it is possible to determine the thermal shock behavior of ceramic materials by the combination of experimental testing and numerical simulation.}, language = {en} } @inproceedings{HaaseReinholdWolletal., author = {Haase, Florian Vincent and Reinhold, Maximilian and Woll, Ralf and Wolf, Matthias and Seidlitz, Holger}, title = {Reliability capability assessment of cooperative networks using the example of developing demonstrators of structured materials}, series = {Risk, Reliability and Safety: Innovating Theory and Practice, Proceedings of the ESREL 2016, Glasgow (United Kingdom)}, booktitle = {Risk, Reliability and Safety: Innovating Theory and Practice, Proceedings of the ESREL 2016, Glasgow (United Kingdom)}, editor = {Walls, Lesley and Revie, Matthew and Bedford, Tim}, publisher = {CRC Press}, address = {Boca Raton}, isbn = {978-1-138-02997-2}, pages = {1323 -- 1329}, language = {en} } @inproceedings{KloshekKaneneksDuedingetal., author = {Kloshek, Alexander and Kaneneks, Michael and D{\"u}ding, Michael and Wolf, Matthias and Michailov, Vesselin}, title = {Unterpulverschweißen in Steig- und Querposition}, series = {Tagungsband, 24.

This significantly reduced the susceptibility of the ceramic to cracking. A high-speed camera investigation into the wetting and infiltration behavior of a Cu-melt into LaCrO₃ with a porosity of ~63 vol\% was performed. By adjusting the focal distance with a constant laser power of 300 W, the Cu-melt was rapidly infiltrated into the ceramic preform in 10 seconds. This was completed under atmospheric air conditions, without added inert gas. The joining process developed can be used to fabricate ceramic/metal joints with targeted (micro-) structure properties by adjusting the infiltrated melt and the infiltration depth, which would be suitable for many applications, such as multifunctional devices, solid oxide fuel cells or heating elements.}, language = {en} } @techreport{FeindtWoltersBackesetal., author = {Feindt, Peter H. and Wolters, Volkmar and Backes, Gunter and Bahrs, Enno and Brandt, Horst and Engels, Eve-Marie and Engels, Johannes and Graner, Andreas and Hamm, Ulrich and Herdegen, Matthias and Isselstein, Johannes and Schr{\"o}der, Stefan and Tholen, Ernst and Wagner, Sven and W{\"a}tzold, Frank and Wolf, Heino}, title = {Schutz tiergenetischer Ressourcen im Tierseuchenfall - Vorschl{\"a}ge zum Schutz von Tierbest{\"a}nden in Nukleus- bzw.

The main objective of this paper is to present a robust writer verification system by using cursive texts as well as block letter words. To evaluate the system, two datasets have been used. One of them is called Secure Password DB 150, which is composed of 150 users with 18 samples of single character words per user. Another dataset is public and called IAM online handwriting database, and it is composed of 220 users of cursive text samples. Each sample has been defined by a set of features, composed of 67 geometrical, statistical, and temporal features. In order to get more discriminative information, two feature reduction methods have been applied, Fisher Score and Info Gain Attribute Evaluation. Finally, the classification system has been implemented by hold-out cross validation and k-folds cross validation strategies for three different classifiers, K-NN, Na{\"i}ve Bayes and Bayes Net classifiers. Besides, it has been applied for verification and identification approaches. The best results of 95.38\% correct classification are achieved by using the k-nearest neighbor classifier for single character DB. A feature reduction by Info Gain Attribute Evaluation improves the results for Na{\"i}ve Bayes Classifier to 98.34\% for IAM online handwriting DB. It is concluded that the set of features and its reduction are a strong selection for the based-password handwritten writer identification in comparison with the state-of-the-art.}, language = {en} } @techreport{FeindtWoltersBackesetal., author = {Feindt, Peter H. and Wolters, Volkmar and Backes, Gunter and Bahrs, Enno and Brandt, Horst and Engels, Eve-Marie and Engels, Johannes and Graner, Andreas and Hamm, Ulrich and Herdegen, Matthias and Isselstein, Johannes and Schr{\"o}der, Stefan and Tholen, Ernst and Wagner, Sven and W{\"a}tzold, Frank and Wedekind, Helmut and Wolf, Heino}, title = {Wege zu einem effizienten Waldnaturschutz in Deutschland: Stellungnahme Januar 2020}, address = {Berlin}, pages = {69}, language = {de} } @misc{FoersterSchenkZollneretal., author = {F{\"o}rster, Stefan and Schenk, Sebastian and Zollner, Eva Maria and Krahn, Oliver and Chiang, Cheng-Tien and Schumann, Florian O. and Bayat, Alireza and Schindler, Karl-Michael and Trautmann, Martin and Hammer, Ren{\´e} and Meinel, Klaus and Adeagbo, Waheed A. and Hergert, Wolfram and Flege, Jan Ingo and Falta, Jens and Ellguth, Martin and Tusche, Christian and DeBoissieu, Marc and Muntwiler, Matthias and Gerber, Thomas and Widdra, Wolf}, title = {Quasicrystals and their Approximants in 2D Ternary Oxides}, series = {Physia Status Solidi B}, volume = {257}, journal = {Physia Status Solidi B}, number = {7}, issn = {0370-1972}, doi = {10.1002/pssb.201900624}, pages = {11}, abstract = {2D oxide quasicrystals (OQCs) are recently discovered aperiodic, but well-ordered oxide interfaces.
