Uniaxial tension and compression tests were performed to obtain experimental data for identification of material parameters of rubber. For this, the Mooney-Rivlin hyperelastic material model was used. Since the possibility to change sample stress states from pure shear to combination of tens...

This paper presents an overview of training strategies for optical character recognition of historical documents. The main issue is the lack of the annotated data and its quality. We summarize several ways of synthetic data preparation. The main goal of this paper is to show&#...

One important part of the design process of composite structures is the investigation of quality of the elementary material. There are a number of characteristics which may have the influence on the quality of the final composite material. Widely used fiber volume fraction has ...

In a recent paper in Electron. J. Combin. 23 (2016) Estélyi and Pisanski raised a question whether there exist vertex-transitive Haar graphs that are not Cayley graphs. In this note we construct an infinite family of trivalent Haar graphs that are vertex-transitive but non-Cayley.&...

Students often ask what theoretical subjects will teach them for their future careers. It is advisable to show real problems during their courses which are solved by experts in practice or doctoral students. One such problem is the sharpening of a hobbing worm milling cutter.&...

In this paper a new algorithm for the generation of periodic microstructures with regular, irregular and random morphology is presented. It is used for the analysis of anisotropy of unidirectional continuous fiber-reinforced composite material. The generator algorithm is based on pseudo-physical&...

The article is a step forward towards improving image segmentation using a popular method called Graph-Cut. We focus on optimizing the algorithm for processing data, in which the target object occupies only a small portion of the total volume. We propose a twostep procedure. A...
