Adding carbon-fibers (CF) has been one strategy to increase the mechanical performance of different thermoplastics. One challenge is to determine the amount of CF needed to increase the mechanical performance without affecting the "printability" of the compounds. In this paper, different amounts (10, 15, and 20 vol.\%) of CF were added to recycled polypropylene (rPP) and polyamide 12 (PA12). A compatibilizer was used for rPP, but not for PA12. Filaments for MEAM were extruded from the different compounds and the viscosity as well as the tensile properties were measured and compared to the processed polymeric matrices. It was observed that the viscosities at the angular frequencies relevant for MEAM (100 to 200 rad/s) were not significantly different for rPP+CF compounds, but it was higher for PA12+CF compounds. As expected, the elongation at break significantly decreased with the addition of CF for all compounds. For the composites with an rPP matrix, the Young's modulus and the ultimate tensile strength (UTS) continuously increased as the CF content increased to 20 vol.\%. For PA12-based materials, the Young's modulus and the UTS increased with CF content, but adding more than 15 vol.\% did not further improve these values. Therefore, it was concluded that for PA12 the maximum amount of CF that should be added was 15 vol.\%. Using scanning electron microscopy, it was observed that the CF were homogeneously dispersed in the rPP matrix, but not so well in the PA12 matrix, with fibers being more concentrated towards the rim of the filament. Finally, filaments of rPP, rPP+20CF, PA12 and PA12+15CF were used to print complex geometries by means of MEAM, and it was observed that CF helped to reduce the warpage compared to the unfilled filaments. A potential application of this phenomenon could be the reduction of the bed temperature to develop a more energy efficient MEAM process for semi-crystalline polymers.}, subject = {Additive Manufacturing}, language = {en} } @inproceedings{RauerWoeberAburaia, author = {Rauer, Johannes and W{\"o}ber, Wilfried and Aburaia, Mohamed}, title = {An Autonomous Mobile Handling Robot Using Object Recognition}, series = {Proceedings of ARW \& OAGM Workshop 2019}, booktitle = {Proceedings of ARW \& OAGM Workshop 2019}, subject = {Mobile Robotics}, language = {en} } @inproceedings{WoeberAburaiaAburaiaetal., author = {W{\"o}ber, Wilfried and Aburaia, Ali and Aburaia, Mohamed and Kubinger, Wilfried and Otrebski, Richard and Engelhardt-Nowitzki, Corinna and Markl, Erich}, title = {Digital Manufacturing \& Robotics im Department Industrial Engineering}, series = {Konferenz der Mechatronik Plattform Autonome mechatronische Systeme}, booktitle = {Konferenz der Mechatronik Plattform Autonome mechatronische Systeme}, pages = {20 -- 21}, abstract = {Digitalisierung und Automatisierung in produzierender Industrie sind Schlagw{\"o}rter heutiger Forschungsbarbeiten am Department Industrial Engineering der Fachhochschule Technikum Wien.

In contrast to this traditional approach, the progress in deep learning has led to numerous applications ranging from specimen identification to object detection. Typically, these models tend to become black boxes, which limits the usage of recent deep learning models for biological applications. However, the progress in explainable artificial intelligence tries to overcome this limitation. This study compares the explanatory power of unsupervised machine learning models to traditional landmark-based approaches for population structure investigation. We apply convolutional autoencoders as well as Gaussian process latent variable models to two Nile tilapia datasets to investigate the latent structure using consensus clustering. The explanatory factors of the machine learning models were extracted and compared to generalized Procrustes analysis. Hypotheses based on the Bayes factor are formulated to test the unambiguity of population diversity unveiled by the machine learning models. The findings show that it is possible to obtain biologically meaningful results relying on unsupervised machine learning. Furthermore we show that the machine learning models unveil latent structures close to the true population clusters. We found that 80\% of the true population clusters relying on the convolutional autoencoder are significantly different to the remaining clusters. Similarly, 60\% of the true population clusters relying on the Gaussian process latent variable model are significantly different. We conclude that the machine learning models outperform generalized Procrustes analysis, where 16\% of the population cluster was found to be significantly different. However, the applied machine learning models still have limited biological explainability. We recommend further in-depth investigations to unveil the explanatory factors in the used model.
