The paper discusses in detail the construction of the Core Less Axial Flux Permanent Magnet generator simulation model. The model has been prepared in such a way that full compatibility with the elements of the SimPowerSystem library of the Matlab/Simulink package is preserved, which allows easy use of the presented simulation model for testing the work of the generator as part of a larger system. The parameters used in the model come from the MES 3D calculations performed in the Ansys/Maxwell software, for a machine prototype with a rated power of 2.8 kW, which was then used to experimentally verify the correct operation of the presented model of machine.
This paper is focused on the manufacturing and properties of light weight aggregates made from local waste materials. The waste materials were car windshield glass contaminated by PVB foil, fly ash, mine slates as well as wastes after toothpaste production. The main aim of the research was to combine car windshield glass and the aluminosilicate coal mine slates as a basis for light weight aggregates manufacturing. Fly ash were added in order to modify rheological properties of the plastic mass. Toothpaste wastes were introduced as a source of carbonates and CO2 evolution during thermal treatment. After milling and mixing all materials they were pressed and sintered at temperature range of 950°C-1100°C in air. The results show that it is possible to receive light weight aggregates only from the Silesian local waste materials. The significant influence of sintering temperature on properties of aggregates was observed.
Self-control is a complex and multifaceted construct that can be regarded as an individual trait that follows its own developmental trajectory. In the presented study we used NAS-50 for the assessment of self-control in adolescents and young adults. Since the questionnaire has not been used before in underage participants we tested its reliability in adolescent and adult samples. We also investigated possible age and gender differences in self-control abilities as well as relations between NAS-50 and behavioral measures of cognitive control and impulsivity. Although the sample was quite small, the reliability of the questionnaire was similar to the results achieved by its authors. According to the predictions in the literature we did not find relations between NAS-50 and behavioral measures of cognitive control and impulsivity. We also did not observe significant age differences in the assessment of self-control abilities. The theoretical relevance of our results is discussed.
