    Abstract: An algorithm for calculating the defect structure of semiconductor silicon crystals was proposed. The proposed approach makes it possible to calculate the sizes, distribution densities of grown-in microdefects at any point of the crystal. Calculations are performed by using and analyzing the thermal conditions of crystal growth in the temperature r... Show More

    Abstract: A promising alternative of the conventional camshaft in internal combustion engines is one that replaces the camshaft with electromagnetic actuators. This so-called camless system provides great opportunities for the automotive industry. To investigate the advantage of the system against the cam system firstly, we modelled the lift profiles of both... Show More
