M. Łucarz, AGH University of Science and Technology, Faculty of Foundry and Enginering, Kraków, Poland The application of thermogravimetric analysis can be very useful in the method since an extensive range of resins is used in founding. The thermal analysis performed for three different binders indicated the similar destruction mechanism. Along with the temperature increase the mass decrease o...

The main goal of this note is to provide a complete tool for verifying whether polytopes of complex polynomials whose degrees differ at most by one are Hurwitz stable. The results extend some classical theorems, such as the Edge Theorem given by Bartlett, Hollot and Huang (1988), its generalizations proposed by Sideris and Barmish (1989), Fu and Barmish (1989), and the eigenvalue criterion give...

This article presents a summary result of the survey on the need for mechatronics education. The study was conducted as a cooperation project between two teams established at two universities: AGH-UST from Poland and University of Stavanger (UiS) from Norway. Both companies and High School Pupils are surveyed in this project, but only feedbacks from the former are analyzed in this article. As a...

Eukaryotic genomes contain many conserved regions of unknown function. Accurately assessing the protein coding potential of these regions is a key step in annotation. We develop three protein coding measures that directly assess conserved regions in multiple sequence alignments of many species: one based on phase-shifts induced by alignment gaps, another based on the 3rd position mutation asymm...

K. Kaczmarska, B. Grabowska, D. Drożyński, AGH University of Science and Technology, Faculty of Foundry Engineering, Krakow, Poland The results of preliminary tests of selected properties of the moulding sands with the binder in the form of a 5 % water solution of the sodium salt of carboxymethyl starch (with a degree of substitution (DS) of 0,2 and 0,87) are presented in this study. The mouldi...

Mickiewicza 30, PL-30-059 Kraków, Poland Simulations are performed according to the Axelrod model of culture dissemination, with modi ed mechanism of repulsion. Previously, repulsion was considered by Radillo-Diaz et al. as dependent on a prede ned threshold. Here the probabilities of attraction and...
